Where does Fairhaven Supply Co keep its books?
The merchant picks their ledger and authorizes once. This is the whole onboarding page — Meridian Pay builds it against one API and it works for every ledger below, in every market, with no per-ERP connector to maintain.
+ 28 more that support this flow — QuickBooks Desktop, Zoho Books, FreshBooks, Odoo, Exact Online, Moneybird and more. 34 accounting connectors expose everything this demo reads; Apideck connects to 48+ accounting & ERP systems through one API.

}In Live mode this launches the real @apideck/vault-js widget. In Mock mode it opens a stand-in with the same UX.
Scope the picker to the ledgers you support with ?connectors=xero,quickbooks,sage-business-cloud-accounting — useful when your first release covers three and you do not want to imply the rest.
