Mercury Banking Integration connects them. Bank activity flows into ERPNext for reconciliation, invoices can be paid through Mercury, and payroll and vendor payments go out from ERPNext without a second login. It's built for finance teams that want the ERP to stay the source of truth. ## Features **Bank sync.** Mercury accounts become ERPNext Bank Accounts, with hourly transaction import, backfill, and webhook or polling updates. **Accounts receivable.** Payment Requests become Mercury invoices with a pay link and overdue reminders. **Payouts.** Pay salary slips and suppliers by ACH, either sent directly or held for approval by a second Mercury user. **GL coding.** Map your chart of accounts to Mercury GL codes and book journal entries automatically, with a daily sweep for transactions coded late. **Attachments.** Receipts and files on Mercury transactions are imported to ERPNext. **Audit log.** Every inbound event and outbound call is recorded as an Integration Request. ## Getting started Start with a sandbox token in Mercury Settings, then sync accounts and backfill transactions. The [README](https://github.com/Avunu/mercury_banking_integration#setup) explains each step, the token scopes you need, and known constraints such as USD-only receivables.
