Hello everyone,
In case anyone is interested, we have a WHMCS module which you can make the electronic invoice issue in Ecuador. This module is integrated to our electronic invoicing system which is responsible for signing and issuing.
In the WHMCS, in pre-invoices a "Billing" button will appear in such a way that when clicking, the respective invoice or electronic credit note is generated and sent.
Customers can download their electronic invoices from our web application of our Electronic Billing system.
In addition, we have an additional module so that your customers from WHMCS (client area) can view (in listing) and download the RIDE (PDF) and XML files from the electronic vouchers.
Any concerns you have about it or want more information please let me know.
Thank you
