How to choose your billing day and billing mode

In the sidebar, go to Settings, then the Money tab, then the "How you bill clients" sub-tab. Your billing settings are in the Billing cycle card.

Select Billing mode: choose "In arrears. Bill after the work" to bill for work completed up to your last billing date, or "In advance. Bill for the period ahead" to bill for work up to your next billing date, plus anything still unbilled.

Select Monthly or Weekly as your Primary billing cycle. This is the default used for all clients unless you set an individual client on their own cycle.

If you chose Monthly, pick a Billing day of the month between 1 and 28.

If you chose Weekly, pick a Billing day of the week, work done on or before this day counts as due.

On monthly billing you'll see a "Bill to the end of the month" toggle. It's off by default, so the period runs from billing day to billing day.

Turn it on and the period snaps to whole calendar months instead. With a billing day of the 28th in arrears, the bill raised on 28 September covers 1–30 September. In advance, that same bill covers the whole of October.

Expand Advanced settings to set the day PawLoop would use if an individual client is switched to the other cycle from their own profile.

Click Save billing settings. You'll see a confirmation once it's saved.
