Sage Accounting (formerly Sage One/Sage Business Cloud Accounting) is cloud-based accounting for small businesses—typically 1-50 employees. Sage 200 is mid-market ERP software with advanced features for larger businesses including multi-company, advanced stock control, and project accounting. Field Ascend integrates with both.
The integration syncs invoices (one-click posting), customers (bi-directional), payment status (automatic), VAT rates (mapped), nominal codes (configurable), and credit notes. Invoice numbering can be forced from Field Ascend or auto-generated by Sage.
Yes. The integration fully supports UK VAT rates including standard, reduced, zero-rated, and exempt. Since invoices post directly to Sage, they're automatically Making Tax Digital (MTD) compliant—Sage handles all HMRC submissions.
Currently, Field Ascend integrates with Sage Accounting (cloud) and Sage 200 via their APIs. Sage 50 (desktop) doesn't offer the same API access required for real-time sync. If you're using Sage 50, consider migrating to Sage Accounting or Sage 200.
If you disconnect, existing posted invoices remain in Sage. No data is deleted. You can reconnect at any time and resume syncing. Invoice IDs are preserved, so Field Ascend still knows which invoices were previously posted.
