Sometimes you need to collect payments on exact calendar dates—Black Friday, the first day of each school term, etc. PayWhirl’s Specific Day(s) frequency lets you build those schedules without workarounds.
How to set up a “Specific Day(s)” plan
Create or edit your plan in PayWhirl.
In Charge on, choose Specific Day(s).
Click dates on the calendar to add one or many billing days.
Each selected date becomes one installment.
Mix and match freely for irregular schedules.
Save the plan.
You can add as many billing dates as you'd like to plans with a specific date(s). This flexibility allows you to create plans with custom billing schedules and completely custom billing dates.
What subscribers will see:
Future dates only – Past dates are skipped automatically; customers pay only upcoming installments.
Locked installment count – When a shopper joins, the number of payments left equals the number of future dates at that moment.
Automatic cancellation – After the last listed date is charged, the subscription ends unless you chain it to another plan.
NOTE: Adding new calendar dates later does not change the remaining installments for existing subscribers.
Planning to add dates over time?
Chain the plan to a secondary plan using “After last installment, move to…” so the customer is re-enrolled with the newly added dates.
Example:
Plan lists Jan 1, Apr 1, Jul 1, Oct 1.
A shopper joins on Feb 10 → 3 installments remain.
If you later add Dec 1, that shopper still has only three payments, and the plan will cancel after Oct 1—unless you chained the plan to another plan.
Quick recap
Use cases: seasonal memberships, school fees, pre-orders shipped on fixed dates, holiday clubs.
Setup steps: choose Specific Day(s) → pick dates → save.
Past dates skipped; future dates billed.
Installments lock at signup. Chain the plan to itself to keep billing if you’ll add more dates later.
