## B2B Edition payment method support documentation

The B2B Edition Payments API overview now documents which payment methods B2B Edition supports and why some payment providers don't sync reliably.

* **Sync mechanism explained**: B2B Edition syncs its available payment methods from BigCommerce's Get All Payment Methods endpoint, which only returns gateways with checkout module representation.
* **Supported and unsupported gateway tables**: added reference tables listing which gateways have checkout module representation (and are therefore supported by B2B Edition) and which are BigPay-only integrations that aren't returned by the sync endpoint.
* **Troubleshooting guidance**: added guidance for when a configured payment method doesn't appear in, or disappears from, Company payment settings.
