I'm just sharing some thoughts here. There is a processing fee per transaction, which would result in paying more fees for a weekly client compared to a monthly client. However, the difference may not be significant.

Currently my contracts are set up to use Zelle for clients that prefer to pay weekly, have them schedule automated payments for 3 months (13 weeks) at a time, and send a screenshot of the recurring payment as proof of their agreement to our contract terms. For the few that choose to pay weekly, this eliminates credit card processing fees. However, it does require monitoring their account to ensure that their weekly payments are actually being sent.

I didn't think about changing the due dates in CRC as a workaround.
