Custom CRM and ERP Software Development

Off-the-shelf CRM and ERP suites are a sensible starting point for many companies. The trouble begins when your workflow does not match the package: staff work around the software or slip back into spreadsheets, licence costs climb with every new user, and each customisation turns into a project of its own. Custom CRM and ERP software contains only the modules you need and mirrors the way your team already works. For internal tools, booking systems or field apps that go beyond CRM and ERP, our custom software development service is usually the better starting point.

Every project starts with an analysis phase. Together we map who enters which data in sales, warehouse, purchasing, production and finance, which approvals each step needs and which reports management relies on. The result is a written scope document covering modules, user roles, integrations and the data migration plan. The written quote and the delivery date in the contract are based on that scope.

The system is built as a modular web application. Customer records and the sales pipeline, quotes and orders, invoicing, stock movements, purchasing, production orders and management reports all share one database. Role-based access control means each user sees only what they need, and critical actions are logged in an audit trail. The interface works on desktop, tablet and phone, so field and warehouse teams use the same live data.

We connect the system to your accounting software, e-invoicing provider, online shop, carriers and bank feeds through the official APIs or file exchange formats each provider offers. Data from Excel files and legacy tools is cleaned, de-duplicated, mapped to the new structure and verified in a test environment before it goes live. Personal data is processed in line with the GDPR, a data processing agreement is available and hosting within the EU is an option. How we plan these connections is described in more detail on our API and system integration page.

Throughout the project you receive weekly progress reports and test working versions as they are ready. At delivery we hand over the source code, the database, the admin panel and all accounts, so there are no per-user licence fees and no lock-in to a single vendor. After launch we provide maintenance, updates and new module development, with scope and duration agreed in the contract. Communication runs in English, German or Polish by video call and email, for companies in Germany, the Netherlands and across Europe alike.
