Credit notes versus refunds for subscriptions, in plain English

A customer emails to say their invoice is wrong. Maybe they were billed for a seat they removed. Maybe a plan change landed on the wrong day. You know the invoice needs fixing, but should you hand money back, or cancel part of the invoice on paper?

Those are two different actions. They do different things in your books, and mixing them up is a common reason bank feeds and invoice lists stop matching.

What a credit note is, and what a refund is

A credit note is a document that reduces what a customer owes you. It corrects the invoice. No money moves when you raise it.

A refund is money going back to the customer. It corrects the cash side. It happens after they have paid.

The two often go together, but they answer different questions:

• Credit note: "Was this invoice right?"
• Refund: "Do we owe this person their money back?"

When to use a credit note

Use a credit note when the invoice itself was wrong, or part of it should not have been charged. Typical cases:

• The invoice is unpaid and the amount is too high. Reduce it so the customer pays the right figure.
• The customer paid, but you would rather keep the money as credit against their next invoice. The credit note, applied to later billing, does that.
• A line was billed twice, or billed for a service not delivered.

The benefit is a clean paper trail. The original invoice stays on record, the credit note points back to it, and anyone reading the books later can see what changed and why.

When to use a refund

Use a refund when the customer has paid and you owe them the money back in their hands. For example, they cancelled and your terms say they are entitled to it, or they were charged in error and want it returned to their card.

A refund on its own does not fix the invoice. If the invoice was too high, you still need the credit note so the invoice and the cash agree. Think of it as two steps: correct the invoice, then return the money if it was already paid.

A simple way to decide

1. Has the customer paid? If not, you only need a credit note (or a replacement invoice, if your accountant prefers that).
2. Was the invoice wrong? If yes, you need a credit note whether or not they paid.
3. Does the customer want money back, or will they use it against the next invoice? Money back means a refund. Keeping it on account means the credit stays as credit.

Write down which of the three applies before you touch anything. It takes a minute and saves a messy correction later.

A short worked example

Say a customer on a monthly plan is invoiced $200 but should have been invoiced $150. The $50 difference is the error.

• If unpaid: credit note for $50. They pay $150.
• If paid and they want the $50 back: credit note for $50 against the invoice, then a $50 refund to the card they used.
• If paid and they are happy to leave it: credit note for $50, and the $50 sits as credit for the next invoice.

The numbers are made up, but the sequence holds for most corrections.

Tax: keep it general and check with your accountant

If you charge GST, a credit note normally needs to reflect the tax on the amount being reduced, so your tax reporting stays in line with what you actually billed. The exact wording and timing rules matter, and they depend on your situation. Ask your accountant how they want adjustments recorded, and what your credit notes must show, before you start issuing them in volume.

What NicelyBilled sends to Xero

If you use the Xero integration, billing events are passed across so your books follow along. These are the pieces relevant to corrections:

• Finalised invoices go to Xero as approved invoices.
• Money received, including payments, top-ups and card payments, goes across as a customer prepayment (credit), allocated to the invoice it settles. Anything left over stays as available credit on that contact.
• When an unpaid invoice is carried into a later one, NicelyBilled sends a credit note applied to the original invoice, so nothing is billed twice.

That last point is the one place the help describes credit notes. The help does not describe other ways of creating credit notes or issuing refunds from NicelyBilled, so I won't claim any. If you need a one-off correction beyond the carried-forward case, check how you want to record it with your accountant and in Xero itself.

Check the sync state of each invoice

Sync runs in the background, within a few minutes, so a change will not appear in Xero instantly. On an account's Invoices tab, each invoice shows its Xero state: Synced, Syncing or Failed. Failed ones have a retry.

If an invoice shows Sync account first, the customer does not yet exist in Xero as a contact. Use Sync to Xero on the account, and the invoices follow.

Importing older history

Anything from before you connected Xero was never sent. Backfill replays it in a fixed order: contact, then invoices, then credit notes, then payments. It is safe to run repeatedly and skips void invoices and payments. On one account, use Sync to Xero (full history). For everything, use Sync all accounts to Xero on the Integrations page.

The backfill numbers show what was queued, not what has landed. Watch the per-invoice and account indicators to see when records arrive in Xero.

A short correction checklist

1. Open the account and find the invoice on the Invoices tab.
2. Work out whether the customer has paid.
3. Decide: credit note only, credit note plus refund, or credit left on account.
4. Confirm the tax treatment with your accountant if GST is involved.
5. Check the Xero state shows Synced, and that the contact balance in Xero looks right.
6. Tell the customer what you changed, in a sentence or two, with the new amount.

Keep the explanation short and specific. "We billed 4 seats and you had 3, so we reduced the invoice by $50" is better than a paragraph of apology.
