About the project

  • Industry

Our client – a thriving company producing household articles – was struggling with common retail goods producers’ problems – manual work with data.

Our client, a large retail chain, was facing challenges with their existing sales system. They had multiple sales stations in each store, but no effective way to centralize and manage data from these stations. They were using the SAP system for their back-end operations, but there was no efficient method for real-time data synchronization between the POS and the SAP system. The client needed a well-executed POS integration with SAP.


Our client has seen a huge waste of time manually entering each receipt, invoice or return into the SAP system. Uploading all financial data did not only take a lot of their employees’ time but also was prone to mistakes. Manual work with data was inefficient and time-consuming.

The company was seeking a way to speed up the process, and to make it faultless. They needed an IT expert who was both familiar with the SAP environment and a custom solution that would work perfectly together.

Scope & Highlights

Intergation of ERP & POS

Automatic upload of financial data

Our Solution

Our team integrated the client’s ERP systems with the POS system. As a result, at the end of the day, all financial data is automatically sent from POS to ERP system – without any help from employees.

We proposed an advanced POS system that could operate on dedicated machines at the client’s stores. This system could function as a single unit or as teams of units, offering flexibility based on the client’s needs.

The POS system was designed to work offline in case of a disruption in connection with the central server, ensuring that sales processes wouldn’t be disrupted. This was crucial for maintaining smooth operations and customer satisfaction.

One of the key features of our solution was the effective data synchronization between the local store database and the headquarters. This allowed for seamless transmission of information directly to the SAP system. All operations carried out in the SAP system, such as issuing invoices, were instantly sent to SAP. Meanwhile, data regarding products, VAT rates, price lists, complaints, and promotions were pulled from SAP and handled by the POS machines.

The POS system was divided into sales and managerial parts. The sales part handled cash register processes, while the managerial part allowed the store manager to manage complaints, check statuses, download price lists from SAP, review products, and more.

Each POS unit was equipped with peripheral devices, such as a fiscal printer, barcode reader, and payment card reader, providing full functionality at the point of sale.

We wrote the solution in .NET using Windows Presentation Foundation (WPF) and for data storage SQL Server Database with NHibernate. ORM was the best choice as a piece connecting the code with the database.


At the end of the project, the systems were seamlessly integrated. Thanks to our work, work in the client’s company has become faster and smoother.

The implementation of our POS system streamlined the client’s retail operations. It allowed for real-time data synchronization with SAP, reduced manual data entry, and provided accurate and up-to-date information. This led to improved operational efficiency and customer satisfaction.

As our POS system was industry-agnostic, it offered the client the flexibility to adapt to different sectors of retail trade. This further enhanced the scalability and usefulness of our solution.

This project underscored the potential of integrating advanced POS systems with back-end operations managed by systems like SAP, leading to improved efficiency and decision-making in retail operations.

Employees do not waste countless hours on manually uploading receipts and invoices to the ERP system. That means huge savings for the company.

Data is uploaded fast and faultless.

All sales and financial data in the ERP system are up-to-date, making the management of the company’s resource policy and sales plans well-informed and much easier.

Technologies we used

.NET, SQL Server Database with NHibernate. ORM (Object–relational mapping) was the best choice for connecting the code with the database.
