Here are your options for accepting a deposit in CBP:
Option A) Create a checkout page and product just for collecting deposits.
To create this you can following along with the video labelled
"How to create a BE Program Checkout Pg"ย in the CBP training modules.
Instead of labelling everything for your BE program you could instead label it with respect to it being for a deposit. Different wording and pricing will be used but the same overall process would apply.
Option B) Send an invoice within CBP
Watch Ryan's the video on the left.
Either way will work! You can do whatever is easiest for you ๐
