Your system isn’t listed?
You’re still covered.

Compleat connects to virtually any finance or ERP system, so you can take control of spend before it happens, no matter what you’re using today.

Not listed? No problem, Compleat can still connect. That means full control over spend, with purchasing and accounts payable working seamlessly.

How we connect to your system


There’s more than one way to integrate with Compleat, and we’ll choose the approach that best fits your setup.

Option 1: Hybrid Cloud Connector

Secure connection for on-premise or hosted systems

If your accounting system is hosted locally or in a private environment, our Hybrid Cloud Connector creates a secure bridge between your system and Compleat.

It allows data to flow safely between platforms without exposing your system to unnecessary risk.

  • Works with on-premise and privately hosted systems
  • Keeps your data secure behind your firewall
  • Enables real-time or scheduled data exchange
  • No disruption to your existing setup
Option 2: Universal Connector

Flexible file-based integration

For systems that don’t support direct API connections, our Universal Connector offers a simple and reliable alternative.

It works by importing and exporting data using structured files — meaning you can still automate purchasing and invoice processing without needing a complex setup.

  • No API required
  • Works with almost any system
  • Simple file import/export process
  • Quick to set up and configure
Option 3: API Integration

Build a fully tailored integration

For businesses that want a more customised approach, our API gives you full control over how Compleat connects to your finance system.

This is ideal if you have internal developers or a partner who can create a bespoke integration.

  • Full flexibility and control
  • Real-time data synchronisation
  • Designed for scalability
  • Works with modern cloud systems
No workarounds. No compromises.
