Bonus: How is your MRR calculated from your Pennylane data?

Case #1: you use posting dates on your Pennylane invoices

In that case, those dates will be the ones used to account for MRR.

Case #2: you use the "Subscriptions" module

In that case, the invoice issue date will be considered the start date of the subscription period. The subscription frequency allows us to determine the end date of the period.

Case #3: set periodicity on plans

You can set a plan's periodicity from the "Data" > "Plans" section

In any case, you can modify an invoice line to convert it from "One-off" to "Recurring"
