Frequently asked questions
How do I charge for a mid-cycle upgrade?
Issue a debit note referencing the subscription invoice for the prorated difference of the higher plan or added seats, with tax. It adds the upgrade to the account cleanly.
Is this the opposite of a subscription credit note?
Yes — a credit note handles downgrades and unused time; a debit note handles upgrades and added seats. Together they keep a changing subscription correct.

What is the difference between a debit note and a credit note?
A debit note increases the amount owed on an invoice already issued — for an undercharge, additional charges or interest. A credit note does the opposite: it reduces or cancels what is owed. Buyers also raise debit notes to notify a supplier of a return or a claim.
