BridgeSync: automating SAP-AFAS integration for a national toll operator

Challenge

Satellic, the operator of Belgium's national truck-tolling system, ran finance on AFAS while a parent-group SAP instance held supplier and accounting data. Every day, the finance team exported flat files from SAP, cleaned them in Excel, and re-imported into AFAS. Errors averaged 6-8 per week. Reconciliation lag at month-end was 4-5 working days. Internal audit had flagged the manual handoff as a material control risk for two consecutive years.

Approach

We mapped every data exchange between the two systems — 11 distinct flows ranging from supplier master data to journal entries. Built BridgeSync as a Node.js middleware layer with idempotent connectors on both sides, structured logging, and a reconciliation queue for any record that failed validation. Deployed in stages, one flow at a time, with parallel-run validation for two weeks per flow before cutover.

Outcomes

• Zero manual data transfers between SAP and AFAS
• Month-end close reduced from 9 days to 4 days
• Audit finding closed in the following compliance review
• Finance team reallocated 2 FTE from data plumbing to analysis
