# Connect your ERP (no code)

> Use BrandGate's ready-made connections instead of the API.

Most brands do not need the API. BrandGate connects to accounting and ERP systems for you, from **Settings → ERP**.

**1. Open Settings → ERP**

You need to be a company admin. Pick your system from the list.

**2. Sign in and approve**

BrandGate sends you to your ERP to approve the connection (for example Fortnox). Some systems use an API key instead; the screen tells you which.

**3. Choose what to sync**

Turn on what you want: orders and invoices into the ERP, and stock from the ERP into BrandGate. Each option explains what it does before you switch it on.

## Who sends the invoice?

Under **Invoice delivery** you choose whether BrandGate or the connected ERP e-mails the invoice. The choice is saved on each invoice when it is created, so changing it later never re-sends or changes old invoices. Credit notes always follow the invoice they credit.

## One owner of stock

Only one system can own stock. If your ERP sets stock inside BrandGate, the [API stock update](/guides/erp-sync#3-stock-from-the-erp) is refused with `409 inventory_managed_by_erp`, which protects you from two systems overwriting each other.

## Which systems?

BrandGate supports several ERP and accounting systems, and availability grows over time. The current list is on the [Integrations](/integrations/overview) page. If yours is missing, you have two options:

* Ask us at [brandgate.dev/contact](https://www.brandgate.dev/contact).
* Build it with the API: follow [Sync an ERP](/guides/erp-sync).

> Building for many brands, as an ERP vendor? Use [OAuth](/oauth) so each customer connects your product themselves.
