# Apideck Open Finance — the ledger half of the picture, any ERP

> How an open-finance / open-banking provider pairs the bank feed it already streams with a customer's invoices and bills — read through one Apideck unified Accounting integration — to verify income, reconcile transactions, forecast cash flow, and hand off flagged gaps to underwriting.

Live at https://openfinance.apideck.dev

Every demo runs on synthetic mock data by default and needs no credentials. Companies, figures, decisions and documents in them are fictional — nothing is real customer, account or financial data, and nothing is financial, lending, tax or investment advice.

## What the demo walks through

1. Connect the customer's ledger through Apideck Vault (the bank feed is already connected)
2. Verify: see both feeds side by side, match transactions to invoices/bills, verify income, write matched items back as paid
3. Forecast: read the bank balance, pull AR/AP aging, blend a 13-week cash forecast, hand off a flagged gap to the Lending demo

## Connector coverage

Measured from the Apideck Connector API, snapshot 2026-08-21. Counts are per unified API and never added together: a connector belongs to exactly one unified API, so a demo spanning two of them is two customer connections.

### Accounting

Required resources — every group, any one member of a group: invoices; bills.

## Notes

- The bank feed (transactions, balances) is deliberately not an Apideck call — it represents data the open-finance provider already has. Only the ledger reads (invoices, bills) and the write-back (payments) go through Apideck.
- Two flows, switchable at the top: Verify (income verification + reconciliation) and Forecast (cash flow visibility, ending in a handoff to https://lending.apideck.dev for SME underwriting).
