We need the option for clients booking multiple treatments in one online checkout to pay one deposit for the booking, not a separate deposit for each individual service. Current issue: If a client books multiple treatments together, the system applies a deposit to each service line. For example, if a client books three laser hair removal treatments in one booking, they are charged three separate deposits. This creates friction at checkout and can discourage clients from booking multiple treatments at once. From the client’s perspective, it feels like one appointment/one transaction, so the deposit logic should be able to reflect that.
