Beyond the first API call

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

Understand every data model

Map each system’s invoices, accounts and tax fields into data your product can use.

Secure every connection

Build and maintain login flows, customer permissions and secure token handling for each system.

Validate real accounting data

Test missing fields, unusual transactions and system differences against real customer scenarios.

Keep it running

Own API changes, failed connections, troubleshooting and ongoing updates.

Repeat for each system

Each additional accounting system brings another integration to build, test and maintain.

One central API connects multiple accounting systems.
  • All Your Data, Unified

    Use a common schema across supported systems, with less system-specific logic in your product.

  • Secure Customer Onboarding

    Let customers authorise access through a guided flow hosted by Zwapgrid.

  • Built for Growth

    Add supported systems and reach new markets through your existing API integration.

  • Test Environments & Realistic Data

    We help you set up test environments and realistic accounting data, so you can validate your integration and go live faster across supported markets.

How it Works?

01

Invite Your Customer

Invite your customer to securely connect to share their accounting data.

02

Customer Chooses Their Accounting System

Your customer will go through the Onboarding Flow, where they choose the system they want to share data from.

03

Customer Consents to Sharing Data

Your customer will sign in into their accounting system, allowing our API to securely share the data with you

04

Access the Data

That’s it - you will now be able to get real-time accounting data straight from your customer's accounting system, through our API!

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
