Case Study: How We Built an AI-Powered Stock Renewal Agent in 4 Weeks

Every growing company has its key to success. In the retail industry, that key is often smart inventory management. Our client, a major e-commerce enterprise, wanted to automate its stock renewal scheduling. Until then, they handled it manually—a slow and inaccurate process that led to frequent stockouts, overstocking, and supply chain delays.

Solution Suggested

After the usual discovery phase, where we interviewed decision-makers and gathered user preferences, our team mapped out a plan for an Intelligent Stock Renewal Agent. Hesitant at first, our client quickly got on board once we described this AI agent’s capabilities:

• Demand forecasting with near-perfect accuracy in predicting stock needs.
• Automated stock replenishment that dynamically places restocking orders based on sales trends.
• Overstock prevention that adjusts supply levels in real time to reduce storage costs.
• Supply chain optimization with AI-triggered orders to cut stockout times.

After we described our development approach, the deal was firmly sealed. We use pre-trained AI models and fine-tune them for your industry needs, cutting the project timeline from months to weeks, 40% faster than the industry average.

Development Process

• We used LSTM and XGBoost models for demand forecasting, achieving 90% prediction accuracy. Thanks to automated hyperparameter tuning and transfer learning, we avoided weeks of manual model adjustments.
• Our team designed an event-driven AI system that automatically adjusted reorder levels.
• We hooked AI directly into supplier APIs, so restocking orders went out instantly based on live sales data and market trends, cutting stockout times by 60%.
• Software engineers built reinforcement learning algorithms that updated reorder thresholds. Everything ran on a containerized microservices setup (Docker, Kubernetes) for fast scaling and low-latency AI processing. 
• Our designers wrapped these high-tech features in an intuitive and easy-to-navigate user interface so employees could quickly learn the new tool.

Using all these pre-built AI components, we delivered the solution at a cost 3X lower than traditional AI projects and in 4 weeks.

Final Results

Three months after the launch, providing ongoing support, we evaluated the impact of the solution:

• Order fulfillment is 60% faster – AI-driven restocking reduces delivery delays.
• Supply chain costs dropped by 30% – Fewer emergency shipments saved money.
• 80% less time spent on manual stock management – Employees focused less on repetitive tasks.

Preparation Steps Before Creating Your AI Agent

The first rule of any smart software investment: make sure your solution solves real business problems. Be it a complex enterprise system or a simple AI assistant, it should deliver measurable results – otherwise, it’s not fulfilling its purpose. Here are three tips from our experts to help you design a practical and useful product.

Define the AI Agent’s Purpose

Don’t rush into development – take a few steps back to understand the purpose of what you’re building. Ask yourself:

• What problem should this agent solve? Do we need it to automate decisions, process data, or improve customer service? 
• Who will use it – internal teams, customers, or external partners? 
• What outcomes should we expect? Lower costs, fewer manual processes, long-term growth support?

AI agents should be a business enabler, not just a software engineering project. Set key metrics to measure its impact – it can be shorter response times, the number of specific tasks handled per period, or revenue and cost savings.

More specifically, if you decide to build AI agents for sales, track how well they’ll increase conversion rates (e.g., by 20% through automated lead qualification). Clear expectations and benchmarking will help you build a product that delivers real value.

Choose Core Features and Capabilities

Modern AI tools can understand, decide, learn, act, and generate human language that sounds perfectly real. But there’s a difference between a high-performing AI agent and a basic one. An effective agent should be capable of these 5 things:

• Context Awareness: Process and interpret user queries through natural language processing (NLP) for chatbots or computer vision for image-based tasks.
• Decision-Making: Solve problems using reinforcement learning, rule-based logic, or probabilistic decision trees.
• Continuous Learning: Learn and get better over time with automated retraining and user feedback loops.
• Seamless Integration: Connect with existing systems like APIs, databases, and third-party tools such as ERP, CRM, or IoT devices.
• Security and Compliance: Make decisions transparently and stay compliant with GDPR, SOC 2, and ISO 27001 for trust and safety.

Once you’ve got these core features, the rest depends on your industry. In healthcare, you need AI to help with diagnostics and process medical data. In retail, it can analyze customer interactions or predict demand spikes. You may start with a Minimum Viable AI Agent. It’s a lean version that you can release, test, gather feedback on, and then refine into a more advanced and relevant product.”

Industry-Specific AI Features and Capabilities 

Find a Trustworthy AI Agent Development Partner

To build an agent, you need significant expertise, the right infrastructure, and continuous support—things that in-house teams often can’t offer. Working with an IT vendor, you can skip the trial and error, saving time and resources. Here’s how to choose an AI development partner:

• Proven Experience: Real cases matter more than experimental projects. Genuine industry experience shows what a company can actually deliver.
• Speed & Cost Efficiency: Look if your partner offers pre-built models, automation frameworks, and effective deployment strategies – they all help get results faster. 
• End-to-End Expertise: A reliable partner has solid technical knowledge and can consult you on data pipelines, API integrations, and security compliance.
• Regulatory Compliance: If your AI makes business decisions, it needs to comply with GDPR, CCPA, SOC 2, and ISO 27001. Ensure your partner follows these standards. 
• Post-Deployment Support: The provider must offer ongoing monitoring, retraining, and optimization to keep your agent in great condition.

How to Create an AI Agent in 5 Steps

AI agent development is a huge task, but without a plan, it can get more complicated. We’ve built multiple AI agents and are still adding projects to our portfolio. That’s why we believe in a practical approach.  

We use pre-built AI components, transfer learning, and automated pipelines. It might sound complex, but it’ll all make sense when we walk you through our process.

Step 1: Choosing the Right AI Model for Your Needs

One common mistake businesses make is choosing an AI model without researching. But if the model doesn’t fit your problem, you might have to redo the entire system later. Let’s go over your options based on actual business needs.

• Predictive AI (Forecasting, Trend Analysis) → LSTMs, XGBoost for demand forecasting, and inventory planning.
• Decision-Making AI (Autonomous AI Agents) → Reinforcement Learning (PPO, DQN) for self-optimizing workflows.
• Conversational AI (Customer Service, HR, Sales) → LLMs + RAG for context-aware chatbots.

In the case mentioned earlier, the client asked for both forecasting and decision-making features, so we stopped at several options: LSTMs for time-series forecasting and XGBoost for event-driven stock adjustments.

We release products in just 4 weeks using existing AI models, not trying to score extra points for reinventing the wheel. Plus, combining multiple models improves forecasting accuracy, although it takes more effort and consideration.”

– commented our COO, Nazar Kvartalnyi.

Step 2: Building Scalable Data Pipelines and Infrastructure

The model’s performance depends on the quality of training data. Using Kafka and Spark, we built a pipeline that handles sales logs, warehouse inventories, and supplier updates. 

We also automated data preprocessing (the computer program cleans and structures the data before it enters the models) and added self-correcting mechanisms to flag inconsistencies and fix them. 

If not for this setup, our agent wouldn’t keep up with demand spikes. But with it, the system can monitor, predict, and adjust stock levels in real time—the kind of flexibility businesses need for agents to work in the real world.

Step 3: Designing AI Decision-Making Logic

Your model may look good on paper, but if AI’s logic is off, it will make unexplainable decisions. And that’s what we wanted to avoid. Here are the principles your model should follow to deliver predictable and unbiased outputs:  

• AI must assess its accuracy before taking action. If confidence is low, AI agents require human supervision.
• Agents have to adjust thresholds dynamically, not relying on fixed values.  
• Users should understand how AI reaches conclusions.  

For our client, we built a flexible logic that adapts to environments—market trends, seasonal shifts, and available warehouse space.

“You cannot trust a system if you don’t understand its decisions. Businesses need clear and auditable reasoning. Smart logic adapts each time it processes new information.”

– explains our AI engineer. 

Step 4: Deployment, Scaling, and Optimization

When we figured out the logic, it was time to launch. Many projects run into trouble at this stage, realizing their working prototype can’t scale. Here’s how we avoided that:  

• Used containerized microservices with Docker and Kubernetes to scale across 100+ locations at once.  
• Set up automated updates with proper MLOps pipelines so the system could learn, adjust, and stay on track.  
• Monitored everything with Prometheus and Grafana to catch any drift or unusual behavior.  

Step 5: Ensuring AI Security, Compliance, and Governance

Even if your AI agent performs miracles, you can still get into legal trouble for not following security standards. That’s why our team treats governance as an integral part of the build, not an afterthought.

• Every agent we build follows strict privacy standards like GDPR, CCPA, SOC 2, and ISO 27001.
• We conduct regular fairness checks to spot hidden bias, especially in areas like hiring or finance.
• We apply XAI (Explainable AI) techniques to keep decisions clear and understandable.

In another project, we built an AI agent with internal bias detection for a financial firm. Every report showed why a specific decision was made so the client could stay compliant with strict FinTech regulations.

How to Build an AI Agent from Scratch and Avoid Mistakes

Building an AI agent feels exciting until you hit your first challenge. But don’t worry, every problem has its solution. In this passage, we’ll talk about challenges in AI development and share tips from our senior AI engineer on how to overcome them.

Poor Data Quality and Limited Availability

Let’s start with the data. AI needs clean, structured data to make decisions. Some businesses neglect this rule and feed their models messy, raw data—no customer histories, outdated sales reports, or files in ten different formats—spending money on a training process that leads nowhere.

“In the context of AI development, your data is your key asset. The more data, the better. And it should be clean, organized, and validated before being sent to AI systems. You won’t sort through thousands of spreadsheets, so we always use automated data pipelines to make this process faster and easier.”

Long Development Timelines and High Costs

Technology is great, but what concerns any business owner is the time and money needed to build an AI agent. And that’s where you can hit another wall—overspending and waiting longer than expected for your product.  

Lots of teams make things harder by designing a solution from scratch. Add in hours of manual tuning and a lack of proper MLOps setup, and what should’ve taken a few months turns into a year-long project. We’ve learned to do things differently. 

“Today, AI projects don’t really take months. There are many models you can adjust to fit your needs, and they’ll work as well as a custom one. The more important thing is agility- find a way to deploy faster because the market is moving quickly.”

AI Fails to Integrate with Existing Business Systems

Another reason why projects fail: they don’t play well with the tools a business already uses. Here are 3 reasons why that happens:

• Siloed AI systems are not integrated with other business tools.
• No APIs stop AI from getting real-time business data.
• Employees are not using AI workflows because the tool doesn’t meet their needs.

“AI only helps when it fits into daily work. If employees jump between platforms or move data by hand, they won’t use it. The best AI setups connect to ERP, CRM, and supply chain systems, making work easier, not harder.”

AI Makes Unexplainable or Biased Decisions

Let’s say your AI system approves a risky loan or suggests a price hike, but it can’t explain why. That’s the black-box problem: AI models can pick up biases from the data we feed them, making unfair decisions. This is a huge issue, especially with rules like the EU AI Act and GDPR getting stricter about responsible AI use.

“If leaders can’t explain AI’s decisions, the tool won’t last. We focus on transparency, so we use SHAP or LIME methods to break down those calculations and conduct fairness audits to find any biases.”
