# Connect QuickBooks

Connect QuickBooks Online so customers, invoices, credit notes and payments are sent to it automatically.

Connect QuickBooks Online once, and Sustainable ERP sends your issued invoices, credit notes and payments to it. Payments you record in QuickBooks come back too.

You need to be an administrator.

1. Open **Settings → Integrations**.
2. On the **QuickBooks Online** card, select **Connect**.
3. Sign in to QuickBooks, choose your company and allow access.

You're brought back to **Integrations**, which shows QuickBooks as **Connected**.

Only documents issued from the day you connect are sent. Older invoices stay as they are.

## Next: map your VAT and accounts

Nothing is sent until you tell Sustainable ERP which VAT codes and accounts to use. See [Map VAT rates and accounts](/settings/accounting-mapping/).

## What happens next

- Each invoice is sent when you issue it, with its customer added to QuickBooks first if needed.
- Credit notes are sent against the invoice they correct.
- Payments you record are sent to your bank account in QuickBooks. If you reverse a payment, it's removed there too.
- Once a day, payments recorded in QuickBooks come back and mark invoices as paid. To check now, select **Check payments now**.

## Reconnect or disconnect

If QuickBooks stops accepting the connection, the card shows **Reconnect needed** and administrators get an alert. Select **Reconnect** and sign in again. Anything waiting is sent once you do.

To stop sending, select **Disconnect**. Nothing already in QuickBooks is deleted.

Xero and Sage show as **Coming later**.
