Your vendor listing can be managed from here.
To create a vendor, navigate to WP Admin Dashboard → WP ERP → Accounting → Vendor. Click on the “Add New” button.
You will get a form to create a vendor. Fill the form out and click on the “Add Vendor” button to complete the process.
That's how you can create vendors in the Accounting module of WP ERP. However, you can also pay vendors and check credits by selecting a vendor from here.
