In highly regulated industries with complex supply chains, such as Oil & Gas, artificial intelligence in Oil & Gas is already being used to automate administrative processes that grow in volume and complexity faster than the teams managing them. Managing invoices, purchase orders (POs), and budgets is a clear example: mission-critical work that is often manual, repetitive, and error-prone.

This was the starting point for a project at an Oil & Gas company that manages purchasing and contracting with thousands of active suppliers. The process relied on emails, cross-checks, and manual data entry into internal systems, consuming significant operational hours and causing frequent delays.

The challenge: invoices with no traceability

The workflow began when invoices arrived by email. In many cases, suppliers did not include the purchase order number (PO), a key data point needed to match the invoice to the correct budget line. This forced the administrative team to review each document, find the right PO, or request a corrected invoice, creating rework and delays.

On top of that, several required checks were also performed manually:

• Amount validation against the PO
• Confirmation that goods were received
• Approval by the requesting area for services

The outcome was predictable: data entry errors, delayed payments, and friction with suppliers.

Artificial intelligence in Oil & Gas: automating the invoice and PO workflow

The solution introduced an AI agent as the first layer of administrative processing. All invoices are sent to a dedicated inbox, where the agent automatically reads them and extracts the relevant information.

The first control happens immediately: the system detects whether the invoice includes the PO number. If it cannot find it, the agent automatically replies to the supplier requesting a reissued invoice with the correct PO number, without human intervention.

When the invoice contains the PO number, the agent connects to the purchasing system, matches the invoice to the corresponding PO, and links it to the assigned budget line. If the amount matches what was agreed in the PO, the invoice is routed to the responsible owner for approval with full context.

Automated validations based on purchase type

The system distinguishes between physical goods and services:

Physical goods: billed quantities are automatically checked against delivery receipts. Receipts are photographed upon delivery and read by AI to validate consistency against what remains open on the linked PO.

Services: the invoice is routed to the requester for approval or rejection, with complete contextual information.

Once approved, the invoice is automatically posted to the ERP, eliminating manual entry.

Results: efficiency, control, and transparency

The automation reduced time spent on repetitive administrative tasks by up to 80%. The team stopped spending hours on manual checks and email back-and-forth, and shifted focus to budget control and exception handling.

Traceability also improved significantly: each invoice is linked from the start to a PO, a budget line, and an approval owner, reducing errors, delays, and supplier disputes.

From manual operations to intelligent management

This case shows how artificial intelligence in Oil & Gas can be applied in a practical way to critical administrative processes. By automating controls and orchestrating approval flows, AI does not replace human oversight, it strengthens it, freeing up time and reducing operational risk in environments where traceability is essential.

At TAM, we work with finance, procurement, and operations teams to automate high-volume administrative processes using AI agents, reducing errors and accelerating approval and payment cycles.

Here are five common mistakes companies make when hiring a development firm, and how to avoid them from the start.

Misaligned Expectations

Many issues arise because clients and vendors have different interpretations of terms like “simple app” or “minimum viable product.”

How to avoid it:

Clearly define the scope, goals, and key features. Ask the company to confirm these in writing to ensure you’re aligned.

Not Checking Relevant Experience

Some companies may present well but lack real-world experience with the type of solution you need.

How to avoid it:

Request specific examples of similar projects. Ask how they handled technical or business challenges. Check if they’ve worked with companies your size or in your industry.

Choosing Based on Price Alone

Cost matters—but it shouldn’t be the only factor. A low quote may reflect lack of experience, poor planning, or incomplete deliverables.

How to avoid it:

Compare proposals at the same level of detail. Evaluate what’s included: design, QA, documentation, support, etc.

Vague or Undefined Deliverables

It’s common to assume you’ll receive a finished product, but often it’s unclear what exactly is being delivered or how.

How to avoid it:

Define concrete deliverables for each stage. Ask for access to functional versions, technical documentation, and user manuals as needed.

Working with a Vendor, Not a Partner

A strong development company doesn’t just follow instructions—they co-create with you, offer suggestions, and bring valuable insights to the table.

How to avoid it:

Look for a team that understands your business, asks the right questions, and is committed to outcomes—not just hours billed.

1. Shortage of Financial Resources

One of the biggest challenges for any startup is securing enough capital to operate and grow. A lack of funding can severely limit operations, talent recruitment, and marketing campaigns.

To prevent this from becoming a headache, it’s advisable to explore various funding sources, from angel investors and venture capital to crowdfunding and government loans. It’s also crucial to maintain a tight budget and prioritize expenses that generate a return on investment.

2. Finding the Right Team

Startups need teams that not only share the founder’s vision but also possess the necessary skills to scale the business in rapidly changing contexts. A team is required that not only shares the founder’s vision but is also adaptable and resilient. The ability to work under pressure, creatively solve problems, and adapt to new situations are essential qualities in an environment that can often seem chaotic and uncontrolled.

For this reason, when hiring, evaluate not just technical skills and experience, but also the candidates’ ability to handle uncertainty and change. Consider including hypothetical scenarios in your interviews to see how candidates tackle complex problems and whether they can think on their feet when faced with unexpected challenges. This ensures that your team is not only competent but also capable of leading the company forward in times of turbulence.

3. Scaling Prematurely

Many startups make the mistake of scaling too quickly, which can lead to excessive spending and an infrastructure inadequate for handling growth. This can result in an operation that is unsustainable in the long term.

The key is to ensure that market demand justifies growth and that internal processes are optimized to support a larger expansion. Scaling should be gradual and well-planned.

4. Product Development Without Customer Focus

It’s common for entrepreneurs to fall in love with their solution without sufficiently validating whether it truly solves a significant problem for their customers.

To reduce biases, implement an iterative approach to product development. Use prototypes and MVPs (minimum viable products) to gather customer feedback before proceeding with more costly and extensive developments. Market validation is crucial. Working on a design and discovery process that brings your business idea down to earth will prevent you from making many mistakes.

5. Ignoring the Competition

Underestimating the competition is a very common mistake in the world of startups. It’s essential to understand who your direct and indirect competitors are and what they offer to know the context in which your project will participate.

Ideally, perform a competitive analysis regularly. Identify your competitive advantages and look for ways to clearly differentiate yourself in the market. Stay alert to industry trends and adapt your strategy as necessary.

As you can see, founding and running a startup can be very challenging, but with preparation and strategy, obstacles can become stepping stones to success. At The App Master, we are dedicated to supporting entrepreneurs on their journey, providing technological solutions that facilitate and enhance their innovative projects. Remember, every problem is an opportunity to learn and grow.

While AI opens up incredible possibilities, it also demands new skills. Here, we explore the five most important ones to stay relevant in this evolving landscape.

Prompt Engineering and Agent Creation

This is undoubtedly the cornerstone skill for 2025. AI-driven agents are not just tools—they’re virtual “robots” that can be trained to handle repetitive and complex tasks. The magic begins with prompt engineering: clear and specific instructions that guide how the AI responds.

Adaptation to Critical Thinking and Creative Problem Solving

AI is powerful, but it’s not infallible. Developers must be critical thinkers, capable of identifying errors, gaps, and potential improvements in AI-generated solutions. This detail-oriented approach also involves questioning how and where AI should be implemented ethically and effectively.

Basic Knowledge of Machine Learning

Not everyone needs to be a machine learning expert, but understanding foundational concepts—like data models, neural networks, and algorithm training—is crucial. This knowledge not only enhances collaboration with AI specialists but also enables informed decisions when integrating existing technologies into projects.

Skill in Working with APIs and AI Tools

From generative models like GPT to data visualization platforms, AI tools come equipped with APIs that make integration into applications seamless. Knowing how to connect these tools and tailor them to the needs of end-users is a critical competitive edge.

Communication and Storytelling Ability

This might come as a surprise, but it’s essential, especially for entrepreneurs. AI doesn’t just solve problems—it also needs to be understood by clients, teams, and stakeholders. The ability to explain complex solutions in simple terms can make the difference between a successful idea and one lost in confusion.

If you’re an entrepreneur, coding might not be your focus, but understanding these skills will help you identify opportunities and collaborate effectively with the right developers. Think of practical examples: How can a virtual agent improve customer service? How could prompts be used to generate marketing content or automated financial reports?

In 2025, developers and entrepreneurs who fully embrace these skills will not only stay ahead of the curve but also gain a competitive advantage.

For those managing apps, it’s important to understand that while acquisition campaigns can drive initial growth, true profitability lies in keeping users active over time. Here are some strategies to optimize user retention and maximize your investment at the same time.

1. Provide a Flawless User Experience (UX)

Ensure the user experience is as intuitive and smooth as possible. Complicated apps that are unresponsive or frustrating drive users away quickly, increasing the need to spend more on acquiring new users.

It’s essential to focus on several key aspects. Load speed and performance help prevent users from abandoning due to frustration. An intuitive design facilitates navigation, while visual consistency builds trust and understanding. Ease of use should be prioritized from the start to minimize the learning curve. Additionally, reducing friction in key processes like registration or purchasing is crucial. Accessibility ensures all users can easily interact, and immediate feedback confirms actions were successful. Finally, optimizing for mobile devices ensures the app works well on various screen sizes and operating systems.

Key tip: Invest in continuous user testing to improve the app’s interface and performance—an investment that will be more cost-effective in the long run than constantly acquiring new users.

2. Segment and Personalize Push Notifications

Push notifications are a powerful tool, but they need to be used strategically. Users who receive relevant, personalized messages are more likely to engage with the app. On the other hand, sending generic or intrusive notifications can alienate users and increase acquisition costs, as you’ll need to replace them.

Key tip: Use behavioral data to send segmented and personalized notifications that add value to the user, encourage engagement, and prevent the loss of valuable users.

3. Foster Loyalty Through Gamification

A highly effective way to keep users engaged and prevent them from abandoning or uninstalling your app is through gamification. Offering rewards, challenges, or badges creates a sense of achievement that motivates users to continue interacting with the app.

Key tip: Implement gamification elements that motivate users without overwhelming the experience, fostering loyalty and reducing dependency on acquisition campaigns.

4. Facilitate Content Personalization

When users feel that an app is tailored to their specific needs, they tend to use it more frequently. Offering personalized recommendations, adapting the interface to user preferences, or suggesting relevant content can keep users engaged and reduce the costs of acquisition by lessening the need for constant user attraction.

Key tip: Analyze user behavior to provide personalized experiences that enhance satisfaction and encourage loyalty.

5. Build Long-Term Relationships Through Effective Communication

The key to retaining users is establishing a strong and lasting relationship with them. Providing efficient customer support, being available to address concerns, and regularly seeking feedback will help users feel valued. Users who feel their needs are heard are more likely to stick around, reducing the need for re-engagement campaigns.

Key tip: Respond quickly to feedback and adjust the app based on user suggestions to enhance their experience and maintain loyalty.

6. Make Continuous and Relevant Updates

Constant updates not only improve app performance but also keep users interested. Showing that your app is continuously evolving demonstrates commitment and gives users reasons to keep using it, reducing churn.

Key tip: Plan frequent updates with significant improvements and communicate their value to users, encouraging their loyalty and saving on advertising costs to acquire new users.

7. Create a Community Around Your App

An active community can be one of the most powerful tools for keeping users engaged. Creating spaces where users can share experiences and offer recommendations builds a sense of belonging that strengthens their relationship with the app. Engaged users are more likely to keep using the app and less likely to leave, reducing costs associated with acquiring new customers.

Key tip: Facilitate community building on social media or within the app itself, where users can interact with each other and with your team, fostering loyalty.

While it may be tempting to focus on user acquisition, retention strategies offer a much higher return on investment in the long run. Keeping your current users engaged and active is more cost-effective than constantly attracting new ones, and it helps build a solid foundation for your app’s sustained growth. Remember, retention not only saves costs but also increases user satisfaction and loyalty, driving your app’s success.

Implementing these strategies will not only improve user retention but also help you optimize your resources and maximize the value of each user.

1. Optimize Energy Consumption

Mobile apps can significantly impact device battery consumption, and reducing that use not only improves user experience but also helps reduce environmental impact. Poorly optimized apps that consume a lot of energy force users to charge their devices more frequently, increasing long-term energy use. To minimize this impact, companies should focus on reducing background processes, optimizing code to be more efficient and lightweight, and improving network usage by cutting down on unnecessary server requests, thus minimizing energy consumption related to data transmission.

2. Reduce Data Footprint

Sending and receiving data consumes energy both on devices and in data centers. Startups committed to sustainability should focus on minimizing unnecessary data transfers to reduce strain on network infrastructure. This can be achieved by compressing files and multimedia resources such as images and videos, caching data locally on the device, and using lazy loading techniques to load only essential content when the user needs it.

3. Efficient and Modular Development

Good software architecture can directly impact app efficiency. Modularity and scalability should be considered from the start, creating lightweight apps that work efficiently on a wide range of devices. To achieve this, it’s essential to divide the app into independently loadable modules, ensure it runs well on low-end devices to extend hardware lifespan, and manage the app lifecycle efficiently to reduce memory and energy usage.

4. Minimalist and Eco-Friendly Design

UI/UX design also plays a crucial role in sustainable development. A simple, lightweight visual interface not only improves user experience but also requires fewer processing and storage resources. By adopting a minimalist design, startups can optimize memory and energy usage by avoiding unnecessary graphics, implementing a dark mode to reduce consumption on OLED and AMOLED screens, and simplifying navigation to reduce the number of interactions and, consequently, the required processing.

5. Adopt Sustainable Servers

Mobile apps often rely on cloud servers for data management, and using efficient data centers is essential to reducing the environmental impact of digital infrastructure. Startups can contribute to sustainability by opting for cloud providers that use renewable energy and efficiently managing cloud usage through techniques like autoscaling, which adjusts server capacity based on real demand, avoiding unnecessary resource usage.

6. User Education and Awareness

Finally, mobile apps can play a role in educating and raising user awareness about sustainability. Companies can include features in their apps to inform users about how to reduce environmental impact by using the app efficiently. This could be achieved by implementing eco-friendly notifications that alert users when they are consuming too much energy or data, and providing settings options that allow users to enable power-saving modes or disable unnecessary features.

Developing sustainable mobile apps is an opportunity for your startup or project to align with the growing demand for responsible tech solutions. Through strategies that optimize energy use, reduce data footprint, and adopt sustainable technologies, it’s possible to create apps that are not only efficient but also environmentally friendly.

For financial managers, managing a budget that is flexible enough to adapt to these changes is essential to ensuring the stability and growth of the company. In this article, we’ll cover key tactics to create and manage agile budgets that enable SMEs to adapt to unforeseen situations and seize new opportunities in the market.

1. Implement Continuous Financial Planning

Instead of conducting annual budget reviews, adopt a continuous financial planning methodology. This means regularly reviewing and adjusting the budget according to market changes or the company’s internal situation. This approach allows for quick adjustments without having to wait for the end of the fiscal cycle.

For instance, you can conduct quarterly or monthly budget reviews to reflect recent changes in revenue, expenses, or market trends. Using software tools that facilitate real-time updates of financial data is key.

2. Create Scenarios and Projections

One of the best ways to be prepared for the unexpected is to anticipate it. By creating multiple financial scenarios based on different market variables (such as an economic recession, an increase in demand, or changes in raw material prices), you can prepare suitable responses for each situation.

It can be helpful to develop at least three different scenarios (optimistic, neutral, and pessimistic) to foresee their impact on the company’s finances. Use these projections to adjust the budget according to each possible scenario.

3. Use Zero-Based Budgeting

Traditional budgets are often based on the previous year’s spending, but in a changing market, starting from scratch can be more effective. Zero-Based Budgeting (ZBB) requires justifying each expense from the ground up, giving companies the flexibility to cut unnecessary costs and reallocate resources efficiently.

To do this, evaluate each expense from its foundation and consider whether it remains necessary in the current context. This approach helps identify areas where costs can be reduced or resources can be strategically invested in new projects.

4. Prioritize Liquidity and Build a Contingency Fund

One of the most important lessons SMEs can learn in times of uncertainty is the importance of maintaining liquidity. Having funds available for emergencies or to seize unexpected opportunities is crucial. Investing in a contingency fund is also a smart tactic to handle unforeseen situations without destabilizing the business.

5. Automate and Monitor Budget Control

Automating certain aspects of financial control, such as real-time expense monitoring and report generation, enables financial managers to make faster decisions based on accurate data. An automated financial system also makes it easier to implement instant adjustments when market changes occur.

6. Collaborate with Other Areas of the Company

An agile budget doesn’t depend solely on the finance department—it must be a collaborative effort with other key areas like sales, marketing, and operations. Maintaining smooth communication between departments will allow budget adjustments to be made alongside business strategies, aligning financial resources with shifting priorities and needs.

It’s essential to organize monthly or quarterly meetings with leaders from other departments to review financial performance and assess the need for adjustments. This ensures that budget changes reflect the real impact on day-to-day operations and business goals.

For SMEs, managing a flexible budget and adapting to a constantly changing market is key to maintaining competitiveness. By implementing tactics such as continuous financial planning, scenario creation, zero-based budgeting, and prioritizing liquidity, SMEs can face the unexpected with greater agility and efficiency. The key lies in combining a solid financial strategy with technology and cross-department collaboration, allowing the company to navigate uncertainty without compromising growth.

A proactive approach to budget management will enable SMEs not only to survive in times of change but also to thrive and capitalize on opportunities that arise along the way.

Companies tend to overly depend on these teams for critical projects, which can create bottlenecks and scalability issues if work is not distributed effectively.

Due to their effectiveness, these teams are often overloaded, which increases the risk of burnout and turnover, affecting the long-term stability of the team.

They may develop rivalries or work individualistically, complicating team cohesion and generating tensions that impact productivity.

Retaining high-performance professionals can be challenging and costly, as they are often sought after by other companies, requiring significant investment in retention.

Leaders face challenges managing highly autonomous individuals with strong opinions, which can make conflict resolution and the implementation of changes or improvements more difficult.

The challenge for a leader is to find a balance between allowing the team to maintain its independence while ensuring they do not stray from the company’s overall goals. Managing expectations and outcomes, ensuring innovation does not compromise operational stability, is a task that requires careful planning and a clear definition of priorities.

Professional and Personal Challenges

Leaders of high-performance tech teams face challenges on both professional and personal levels. Professionally, they must balance the pressure to deliver ambitious results with the need to maintain the team’s quality and efficiency. This becomes even more intense in startups or companies with limited resources, where leaders must be creative with talent and resource management. Retaining talent in such a competitive environment is another key challenge. On a personal level, leaders often experience burnout due to constant pressure and difficulty disconnecting from work. Balancing personal and professional life is challenging, especially when the final responsibility for decision-making rests on their shoulders, often leading to a sense of loneliness and isolation in their role.

Conflict Management and Motivation

Managing conflicts is essential to maintain team effectiveness. Disagreements, especially in technical areas, are common, and the key for a leader is to foster a culture of open communication and resolve conflicts constructively. Acting as an impartial mediator and promoting collaboration rather than competition among team members helps minimize tensions. At the same time, it is crucial to keep the team motivated and continually developing. This can be achieved by offering ongoing training opportunities and recognizing both individual and collective achievements. Assigning challenging projects that allow team members to expand their skills and take on new responsibilities also contributes to a motivating and dynamic work environment.

Another fundamental aspect of leading these teams is the ability to delegate and empower team members. Trying to control every aspect of the work is not only inefficient but can also slow the team’s progress. Trusting team members to make decisions and take responsibility for their areas fosters their professional growth and allows the leader to focus on broader strategic aspects. Ultimately, leading high-performance technology teams requires balanced management of innovation, conflict resolution, and the continuous development of team members, while always considering the professional and personal challenges that these leaders face daily.
