Why teams connect Kustomer and SAP Business One
Close the gap between front office and back office: Kustomer and SAP Business One share customers and status in real time, in both directions.
Kustomer holds the customer relationship; SAP Business One runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.
Stacksync syncs Tags, Notes, Customers, Conversations in Kustomer with Deliveries, Journal Entries, Warehouses, Price Lists in SAP Business One field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
- Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- Two-way sync of business partners between SAP Business One and a CRM so sales edits and finance records converge on one customer master.
- Create sales orders in Business One from e-commerce platforms and sync delivery and invoice status back to the storefront.
Where SAP Business One is the finance system of record: money status on the account
Invoice and payment state from SAP Business One shows on the account in Kustomer, so reps see balances before promising the next order.
One customer master
Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.
Where SAP Business One manages people and org data: keep Kustomer aligned
Owners, territories, and org structure informed by SAP Business One stay current in Kustomer.
