Question regarding card id when customer pays by emailed invoice

This AI generated answer was surprisingly helpful.

A follow-up question:

Does the billing anchor date change when a customer manually pays by invoice? Or does square prorate the charge?

For instance, let’s stay a subscription payment fails, and an invoice is generated. If it takes a customer 1 week to pay, does this just pay in full and activate the subscription as normal?

The same for a paused subscription with an indefinite end date:

Example: A customer’s monthly subscription is on a 1st of the month billing cycle. If the customer pauses a monthly subscription on January 5, and on April 12 attempts to reactivate, does this re-anchor the payment cycle to the 12th? Or does the customer maintain the billing cycle of the 1st, pay for a full month on the 12th, and then again on the 1st?

Also, in this example, would Square disregard the missed February/March payment, and activate it with a single month’s charge in April moving forward?

Thanks.
