What billing intervals are supported?

Daily, weekly, monthly and yearly.

How do variants affect price?

Each variant can add an extra amount to the product price. The unit price on a line defaults to the sum.

Do price changes alter existing invoices?

No. Invoices keep the prices they were generated with.

Can Pip build a catalog for me?

Yes. Describe your business and Pip proposes a small starter catalog, then creates it after you approve.
