The Challenge: Reconciling High Volume Across Complex Partner Chains
Sunday processes millions of restaurant transactions weekly across the United States, France, and the United Kingdom. With diners paying via QR codes, integrated POS terminals, and digital wallets, payments route through multiple acquiring banks, PSPs, and settlement partners along the value chain.
Each payment partner operates on distinct settlement cycles, deducts interchange and processing fees at differing schedules, and provides varied reporting formats. Reconciliations and reporting across multiple formats was complicated and manual.
Key Value Delivered
- Automated reconciliation across multiple payment schemes and partner settlement cycles.
- Cash in transit visibility for accurate restaurant payouts.
- Freed engineering and product teams to focus 100% on revenue-driving features.

Automated multi-partner reconciliation: transaction-level matching across acquiring banks, QR payments, POS terminals, and partner settlement cycles.
