Not asking for an extensive ERP system, but a light one to invoice an issue a Quotation/Estimates. I am aware of all the other modules like:
erp
invoice
simple_invoice
or some other integrations with 3rd parties.
Those modules are either too huge, or just redundant. I need it to work within Ubercart so that it will just use the same libraries, functions, templates and all without re-creating another wheel.
What I'm trying to achieve is the capabilities for the site owner to issue Estimates and Invoices to customers that don't buy it through the Ubercart shopping cart.
So the scenario should be like this:
Site owner issue a Quotation/Estimates to a customer. This, will generate a printed version and a web based with a link/button for user to make payment (Ubercart checkout page with all payment options). Once paid, an invoice receipt will be created with the Quotation number (if any).
*I stated 'if any', for invoices that has no Quotations
Any ideas?
