ERP implementations your team actually uses
The software for sales, inventory and accounting is the heart of the company. We implement InsERT nexo and GT, migrate data from legacy systems, connect the ERP with your online shop and Poland's KSeF e-invoicing system, and train your team.
- InsERT partner: Subiekt, Rachmistrz, Rewizor, Gratyfikant and Gestor
- Migration from GT to nexo and from other systems
- KSeF, shop and bank integrations and management reporting
Why the implementation decides the result
The same software can save your team hours every week or become a constant source of frustration. The difference is the implementation: correctly migrated master data, well configured documents, warehouses and permissions, and staff who know how to do their daily tasks.
We start by talking about your processes, not software features. Only once we know how an order turns into an invoice and a payment do we configure the system and plan integrations. For foreign companies with a Polish subsidiary we also explain local requirements such as KSeF and JPK in English.

Frequently asked questions: ERP and InsERT implementation
How long does an InsERT nexo implementation take?
For a small trading company one to three weeks. With several warehouses, a shop integration and data migration usually four to eight weeks. Most of the time goes into cleaning data and training, not installation.
Can data be migrated from InsERT GT to nexo?
Yes, InsERT provides tools to migrate master data and documents. In practice data must be cleaned up first, you decide which historical documents to move, and the result is checked. We do this on a copy before anything changes in production.
Does InsERT nexo support KSeF?
Yes, InsERT nexo programs support issuing and receiving invoices in Poland's National e-Invoicing System (KSeF). We help configure permissions, tokens and the document workflow.
Can you connect InsERT with an online shop?
Yes. We connect InsERT with shops and marketplaces using ready integrators or via API, synchronising products, prices, stock, orders and sales documents.
Do you work with ERP systems other than InsERT?
We integrate and automate other systems that expose an API or database. When you are choosing a new ERP we help you compare offers independently and estimate the total cost of implementation.
