SECTION 1

Which tool for which situation

SituationUse
You owe the customer something, to come off whatever they buy next: a return, an overpayment, a goodwill gestureCustomer credit (this chapter). It waits on the customer's account until used.
One invoice was simply too high, and you want it reduced nowIssue credit on that invoice: on the Invoices list, open the invoice's More menu and choose Issue credit ("Reduce what is owed on this invoice"). An invoice made by a property lease is the exception: its Issue credit page opens with a banner, "Created by lease ... Credit it from the lease: on its Financials tab, Give a credit applies a credit or concession to this charge (or holds it for the next scheduled charge).", an Open in lease button and no Save. Credit it with Give a credit on the lease (Chapter 13.5).
The invoice is wrong in every way: wrong customer, never deliveredVoid the invoice (Chapter 2.1).
An invoice line has a typo, and the invoice is unpaidEdit the invoice and save the change.
Pro tip: credit, don't fiddle

When a customer has already received an invoice, do not quietly change its price. Give or issue a credit. The customer's copy and your books then tell the same story, and the reason is on record.

SECTION 2

What happens in the books

Giving the credit records a cost and a debt: the business has given something away, and now owes the customer that much.

EventDebitCredit
Credit given, $90.00Expenses: Customer Credits 90.00Liabilities: Customer Credits 90.00
Credit used on invoice 1237Liabilities: Customer Credits 90.00Accounts Receivable 90.00

After both, the liability is back to zero, the customer owes $90.00 less, and the $90.00 sits as an expense on the Profit and Loss.2

PROCEDURE A

Give the credit

Go to Sales → Customer Credit and click + Customer credit.

Give a customer credit form: credit for Pine Ridge Summer Camp, date 10/31/2026, reference Weather 10/29, amount 90.00 in words, what it is for, the Their credit table showing 90.00 left to use after, and the Save buttons; beside it, where it can be used: invoice 1237, 955.00
Figure 1. The credit memo. Numbers match the steps. A the customer's open invoices where the credit could be used.
  1. 1

    Choose the customer 1

    The side panel shows what credit they already have and the invoices it could go on A.

  2. 2

    Set the date 2 and an optional reference 3

    A return slip number, the customer's claim number, or a few words such as "Weather 10/29".

  3. 3

    Type the amount 4

    The box accepts a sum: typing 2*45 gives 90.00. The amount is written out in words beside it.

  4. 4

    Say what it is for 5

    This shows on the credits list and with the entry in the books. Write it for an auditor a year from now.

  5. 5

    Check Their credit 6 and save 8

    The line shows what the customer will have to use afterwards: $90.00. Save and give another 7 clears the form for the next one.

Customer credits page after saving: 90.00 left for customers to use, 90.00 given in the last 365 days, and the credit to Pine Ridge Summer Camp listed as Credit given
Figure 2. Saved. The first card, Left for customers to use, now shows $90.00.
Pro tip: attach the reason

Drop the return slip, or the e-mail that agreed the credit, on Attachments. Credits reduce income, so they are among the first things an auditor or a business buyer will ask to see.

PROCEDURE B

Use it on an invoice

  1. 1

    Open the invoice

    Open one of the customer's unpaid invoices, here invoice 1237.

  2. 2

    Find Use credit in the totals 1

    It appears only when the customer has credit, and says how much: "($90.00 available)".

  3. 3

    Type the amount to use 2

    All of it, or part. Balance due 3 drops at once: $955.00 less $90.00 is $865.00.

  4. 4

    Click Save changes

    If you send the invoice again, the customer sees the credit taken off.

Invoice 1237 totals: total 1,455.00, received minus 500.00, Use credit (90.00 available) minus 90.00, balance due 865.00

SECTION 3

The Customer credits page

Three cards: Left for customers to use (the liability today), Given in the last 365 days, and Used on invoices in 365 days. The list shows each credit given and each use of one as its own row; the tabs Credits given and Used on invoices separate them. Credits that did not start on this page are listed too, with the same Open and More: a credit or concession given from a lease (its reference line reads Concession CN-... (rent reduction), and the lease made its entry, Chapter 13.5) and an opening prepaid balance brought in by an import (Opening prepaid balance as of ...). All of them add to Left for customers to use.

Credits list after use: the credit given, 90.00, and its use on invoice 1237, minus 90.00; given 90.00, used 90.00
Figure 4. The credit given (+90.00) and its use on invoice 1237 (−90.00). "Nothing left to use" under the customer's name.
Caution: credits that are never used

A credit left on the books for years is still a debt. Review Left for customers to use at year-end. Customers you will not sell to again should be contacted about a refund; unclaimed balances may be subject to your state's unclaimed property rules.3

Notes

  1. Notes give background, exceptions and the reasons behind a rule. ↑
  2. BizBooks360 keeps each use as a negative credit of the customer, which is why the list shows the use as its own row of −90.00. ↑
  3. Rules on unclaimed customer balances differ by state. Ask your accountant before writing an old credit off. ↑
