Hello @alemoda,
Assuming that you followed the steps as described in https://woocommerce.com/document/bacs/ and the bank transfer is still not showing, you might be facing a plugin or theme conflict. Read more about plugin and theme conflicts in our Self-Service Guide.
How to test for conflicts
The best way to determine if the issue is being caused by a theme and/or plugin is to:
1. Temporarily switch your theme to Storefront or Twenty Twenty theme.
2. Try to reproduce the problem.
If the problem is resolved, it’s a theme conflict. If not, continue to the next steps.
3. Temporarily deactivate all plugins except WooCommerce. You can do this manually or use a plugin to help (see below for tools).
4. Try to reproduce the problem again. If the problem is resolved, it’s a plugin conflict. To figure out which plugin is causing the problem, continue to the next step.
5. Reactivate your other plugins one by one, testing after each, until you find the one causing conflict.
For more detailed instructions, check out How to test for plugin and theme conflicts.
Please let us know how that goes.
Tools to help with troubleshooting
Meks Quick Plugin Disabler will remember what plugins you had active when you switch it back on.
You can clone your site to a staging environment and perform tests without modifying your live site or impacting customers. Many hosts provide staging facilities, so it’s worth checking in with them. It’s also possible to do it using the free WP Staging plugin.
