Hi there @Bliss_Marsh!
Sounds like you’re thinking in the right direction :slightly_smiling_face: You will definitely need to create a separate record for each individual charge if you want it to be listed separately on an invoice.
Check out my example Invoices and Line Items Base:
This base demonstrates how to build an invoice with separate line items of varying quantities/costs. For your use case, you could equate the [Items] table to the [Services] you provide. I’d also assume you’d want to add a table for [Pets], and it would probably be linked to both the [Line Items] and [Customers] table (this is assuming that a [Customer] can have multiple [Pets], and an [Invoice] may have multiple [Pets] per [Customer]).
Hope this helps to get you going!
