Accounting, billing & payments

Merge Accounting

Read and write accounting data in QuickBooks, Xero, NetSuite, Sage Intacct and other ledgers through Merge's unified Accounting API for one linked account.

Sync customers, suppliers, invoices, bills and journals with any ledger a customer has linked in Merge, without a separate connector per accounting system.

Validation status

Implemented · fixture tested.

Implementation is checked against provider-shaped fixtures for every action, authentication failures, rate limits, pagination and duplicate safety. Provider sandbox and authorised account validation are recorded separately when credential-backed runs are completed.

Authentication

Merge production or test access key plus the linked account token

Plans and access

A Merge account with the Accounting category enabled. Production access keys need a paid plan; test linked accounts are free. Each connection serves one linked account (one end-customer ledger). Writes and fields available depend on the integration and the scopes enabled for the linked account.

Test environment

Merge provides a test access key and test linked accounts (for example the Merge sandbox ledger) at no charge.

Rate limits

Per linked account: 100 requests per minute on Launch, 400 on Professional and 600 on Enterprise plans.

Pagination

Cursor pagination with page_size up to 100; the next cursor is returned in `next`.

Provider events

Merge webhooks for common model changes (for example Invoice.added, Invoice.changed) and sync notifications. Nexra event triggers are not yet available; flows run on demand or on a schedule.

Before you build a flow

Reads come from Merge's synced copy; data freshness follows the linked account's sync frequency (see sync_status.list).
Bills are Merge invoices with type ACCOUNTS_PAYABLE; bills.list and bills.create set that type.
Payments, credit notes, vendor credits, expenses and general ledger transactions are read only; Nexra never records or applies payments or credits.
Writes are synchronous (run_async is not used); bulk endpoints, async passthrough, passthrough requests, attachments upload and field mappings are not automated.
Nexra never deletes linked accounts, regenerates account tokens or changes linked-account scopes.
Remote fields, remote data and integration_params are not mapped; use Merge field mappings for custom fields.
Merge has no idempotency key; uncertain creates are not repeated automatically.

Developer reference

Create the Merge credentials described above with the narrowest permissions your flows need.
In Nexra, open Connect, then Connections, then New connection, choose Merge Accounting, enter its settings and credentials, and tick only the write actions you need. Connection guide
Test the connection, then use its actions as flow sources and destinations. Flow guide
