Why teams connect Rillet and SAP S/4HANA
Keep Rillet and SAP S/4HANA agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.
A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.
Stacksync syncs Custom Field, Account, Customer, Vendor in Rillet with Products / Materials, Billing Documents (Invoices), Deliveries, Journal Entries in SAP S/4HANA in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.
Common use cases
- Sync AR and collection status back to customer success tools ahead of renewals.
- Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.
- Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
- Replicate material master and pricing data to e-commerce and quoting tools.
Migration without a hard cutover
When one system is replacing the other, run both in parallel with records matching until the switch is complete.
One customer and vendor master
Where both systems keep records of the same organizations, corrections made in either propagate to the other.
Subsidiary to headquarters
Where Rillet serves a business unit and SAP S/4HANA is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.
