Will this member-PayPal-Manual system work?

[bobrandklev]

We have a new client with 150 current members and this is their first website.

So we send a printed invoice one last time (this is how they do it annually now) and suggest they go to the website to pay by PayPal and register as a new user or they can mail in a check.

As some of them mail in their check we manually add them to the system/membership level and a username password is sent out to them?

If we manually add them will there be a notice sent to them in 11 months or so saying it's time to renew and again encourage them to pay online?

Over time the checks by mail will stop.

So in summary adding users manually will send their login details automatically?
The users added manually will be sent a reminder to renew in 11 months?
