Overview
Custom accounting software development makes sense when off-the-shelf programs cannot handle your invoicing, pricing or B2B terms. In Tallinn, we build unique accounting programs and integrate online shops with accounting software, so orders, invoices and payments flow automatically and manual data entry is kept to a minimum.
If your business logic is unusual – complex pricing agreements, several legal entities, project-based billing or industry specifics – we build a program that follows exactly those rules. It can be connected to your orders, quotes and work-time data.
We connect your online shop to accounting software, for example Merit Aktiva or Directo, so orders, customers, invoices and payments arrive there automatically. We do the same for B2B sales, where prices, credit limits and payment terms differ per client.
B2B and e-commerce
We have integrated online shops with accounting software and built B2B platforms. We would gladly publish data, mockups and the business logic we built, but we are bound by NDAs. On request, we can share phone contacts of clients who used our services and were satisfied.
We have built order-processing, work-time and quote platforms for sport, logistics, online and offline shops, ship servicing, sale of ship equipment, retail and B2B sale of electrical equipment. Accounting integration is often a key part of these platforms.
We would gladly show data, mockups and the business logic we built, but we are bound by NDAs. On request, we can share phone contacts of satisfied clients so you can ask them directly how the cooperation went.
Estonian companies often use, for example, Merit Aktiva or Directo. Integration options depend on the program's interface (API), so before development we check which data can be exchanged automatically.
Usually not. In many cases it is enough to connect your shop or business platform to the program you already use. We recommend a unique accounting program only when a standard one cannot reasonably cover your rules and workflow.
Yes. We have built platforms for B2B sale of electrical equipment, among others. Client-specific prices, payment terms and invoicing can be set up so that they reach your accounting correctly and automatically.
We have integrated stores and platforms with Merit Aktiva, Directo and other accounting software common in Estonia. For a new program we study its API and propose a solution.
