Accounting for customer payments through personal checking

[Brian]

I use a free online service that allows customers to pay with their debit
card, but this service is linked to my personal checking account. As I get
money in my personal checking through this service, I will periodically
initiate a transfer to my business checking, but it is not an immediate
transfer. How do I account for this in my business books, without making it
look like I'm just contributing endless amounts of my own money to the
business (i.e. through an Owner Contributions equity account)?

Thanks!
