Tell us what you needBuilt for developers
You build the product. We handle consent, authentication, token refresh, data harmonization and connector maintenance.
Test installations and realistic accounting data, with help validating your integration across supported markets.
AI helps you build faster. Running accounting integrations means owning secure access, data quality and ongoing maintenance. We take care of that layer.
Building it yourself
Your team owns the full lifecycle
Map each system’s invoices, accounts and tax fields into data your product can use.
Build and maintain login flows, customer permissions and secure token handling for each system.
Test missing fields, unusual transactions and system differences against real customer scenarios.
Own API changes, failed connections, troubleshooting and ongoing updates.
Each additional accounting system brings another integration to build, test and maintain.

We’re honored to partner with forward-thinking companies and deeply value their insights, feedback, and continued support.
We’ve looked at and assessed a range of integration solutions on the market, and Zwapgrid stood out. Their approach allows us to better understand our customers’ financial situation in real time, while automating a number of tedious and costly tasks behind the scenes.
Thanks to Zwapgrid, we get access to all the data in more countries. Another problem they solntegrating with Zwapgrid was seamless. Their API and documentation made it simple, and it meant our developers could stay focused on building great visualizations for our customers, not integrations.
It also gave us the ability to scale internationally without worrying about local ERP differences.
We have set ambitious goals to deliver an efficient experience to our business customers while reducing the internal stress and risks associated with the assessment and administration of factoring. Standardising how we receive invoice data is an investment that will help us now and in the future. Zwapgrid API.1’s combination of delivering file and API data in a unified way stand out as both unique, powerful and efficient
