Payments module idea

Could we implement a payment receipt module for a company’s long-term subscribers or how can I handle this with Manager?

Can you give me more context on what your business exactly does?

I have a web design business and customers have to pay monthly for maintenance. Do I have to issue an invoice each time or what I should I do?

Yeah, right now you will just need to use Clone function to keep cloning invoices manually. This will not be needed eventually once recurring invoices are implemented.
