While memberships cannot be placed on hold directly, you have the option to suspend billing for a subscription. Here's a step-by-step guide on how to do it:
Navigate to the client's account in the system.
Click the "Invoices" tab.
Click the "See preview" button
In the invoice preview, locate the month you want to pause by adjusting the date range at the top.
Locate the line of the Subscription, click the 3 dots button next to the price, and click Delete
Note: Deleting the desired line will stop the system from generating the invoice for the selected month, effectively "pausing" the subscription for that month. However, if you preview an invoice for a period after the paused month, the system won't reflect the pause until the invoice date for the paused month has passed.
For example, if you pause the subscription for August while in June, the September preview will still add values for the previous months (including August) since they "haven't been paid". Once the August invoice date passes, the September preview will update to include only September's values.
