Square Catering Invoice After a Deposit: Edit the Items, Not the Deposit

Quick answer: yes, as long as the invoice is only partly paid. Square's help article on invoice deposits says you can edit an invoice from Square Dashboard at any time, "even after a partial payment has been made." To change the guest count, change the quantity on the line item. Then check one number before the revision goes out: the new invoice total minus what the client has actually paid should equal the balance Square shows.

Don't use Edit > Deposit for this. Square describes that option as the way to change the deposit amount or its due date. It changes what you're asking the client to pay up front. It doesn't change the food on the invoice, and it doesn't change money you've already collected.

Stop if the invoice isn't in that partly paid state, or if the new total would come in below what the client has already paid. Square's pages don't say what an edit does with the extra money in that case, so this guide doesn't guess.

What Square documents, and what it doesn't

• Documented: editing an invoice in Square Dashboard after a partial payment, in Square's article on managing invoice deposits and payment schedules. The same article names Edit > Deposit for the deposit amount or due date, and says inventory item counts don't drop until the invoice is paid in full. It's written for account owners and team members with the invoices permission.
• Worded differently elsewhere: Square's general create-and-send article lists making "edits to an unpaid invoice" among the things you can do with a sent invoice. The deposit article is the one that covers partial payments directly, so this guide follows it. Neither article walks through the line-item edit screen step by step.
• Not covered by the pages checked: what an edit does when the new total falls below the amount paid; how it changes a milestone schedule, or a percentage deposit that's already been paid; whether it changes an automatic card charge; and how editing behaves while a payment is still processing or disputed.
• Not tested: nothing on this page was tried in a live Square account or with a real payment. All three Square help pages show a last update of April 23, 2026 and were checked on November 1, 2026.

The forum example doesn't add up, and that's the lesson

The question has come up in the Square Community more than once. In a June 2023 post, a wedding caterer who takes a 25% deposit and requires a final headcount within two weeks gave this example: 100 guests at $25 is $2,500, the deposit is $625, and $1,875 is left. The final count is 80 guests at $25, or $2,000. They put the new balance at $1,375 "because client paid $650."

Those can't both be right. $2,000 − $625 = $1,375. $2,000 − $650 = $1,350. That's exactly why the check below uses the amount actually recorded as paid, not the deposit percentage and not anyone's memory of it.

The only reply came from another seller who said adding items had simply updated the balance due, and guessed that removing items would work the same way. That's one seller's report from 2023, not a Square rule. An archived thread from December 2018, with a follow-up in February 2020, asks the same thing in both directions: a client who cut the order, and a guest count that went up. A Square community manager replied there that a deposit doesn't stop you editing the items or the total, but an invoice paid in full can't be edited. That reply is years old. Use Square's current help article as the rule, and treat the forum posts as evidence that the question is real.

Check the invoice's state before you touch it

Open the invoice in Square Dashboard and read its status and the payments recorded on it. Find your row before you edit anything.

Write down four numbers first

1. Each line's quantity and price, for example 100 guests × $25.
2. The invoice total Square shows, including any tax, discount or service charge already on it. Square's create-and-send article lists discounts, taxes and service charges among the things you can add to an invoice, so compare against Square's total, not your hand math.
3. The amount actually paid, from the payments recorded on the invoice. Not the deposit percentage, and not the amount you requested. If you turned on partial payments, Square says the client can pay an amount of their choice, so the deposit you asked for and the money you got can differ.
4. The balance due Square shows now.

Before you change anything, total minus paid should equal the balance. If it doesn't, stop. Something is already on the invoice that you don't understand yet, and editing will only bury it.

Make the edit in Square Dashboard

1. Sign in to Square Dashboard and go to Orders & payments > Invoices. Square's articles give Invoices & Payments or Payments as other names for that first menu.
2. Open the invoice. Square's create-and-send article says you can pick an action from the (•••) menu next to an invoice, or open it and click More. The deposit article refers to an Edit menu.
3. Choose the edit that opens the invoice's line items. Square's articles don't name that menu entry, so look for the one that shows the items. Deposit is the wrong one. If Deposit is the only edit offered, stop.
4. Change the quantity on the line, from 100 to 80 in the example. Leave the price alone unless the price actually changed. Change the quantity rather than adding a discount or a credit line, so the invoice still shows what you're serving.
5. Before you save or send, run the check: the amount paid is unchanged, and the new total minus the amount paid equals the balance Square shows.
6. If it all matches, save and send the revision the way you normally would. Square's deposit steps end with Send for a deposit change, but they don't say whether an item edit notifies the client on its own, so tell the client in writing what changed and what's now due.
7. Open the invoice again after saving. Check the paid amount, the quantities and the balance one more time.

Inventory: Square says item counts don't come down until the invoice is paid in full, and paying the deposit doesn't change them. Lowering a quantity before payoff isn't undoing a stock deduction. If you adjusted inventory by hand for this event, fix that yourself.

Worked example: a fictional wedding, 100 guests down to 80

Everything here is made up. It checks the arithmetic, not what Square will display on your account. One line item, a 25% deposit paid in full by card, nothing pending, no milestones, no automatic charge, and no tax, service charge, tip or fees.

The check: $2,000.00 − $625.00 = $1,375.00. If that's the balance Square shows and the paid amount still reads $625.00, the revision is right.

If the screen shows one of these instead, don't save or send:

• $2,000.00 due: the $625.00 isn't being credited. That's the outcome the 2023 caterer was worried about, with the client asked for the whole new amount.
• $1,875.00 due: the total didn't change. The edit didn't take.
• $1,500.00 due: suggests the math is running on 25% of the new total ($500.00) instead of the $625.00 actually paid.
• $1,350.00 due: that's the forum's $650 figure. The paid amount doesn't match your records.

Any of those means stop and take your before-and-after numbers to Square support.

If the count goes up

Same fictional event, final count 110: 110 × $25.00 = $2,750.00. Minus the $625.00 paid, the balance should be $2,125.00. If the invoice has milestone payments, the remaining payments shown should add up to $2,125.00.

If the client paid a different amount than you requested

Say partial payments were on and the client paid $700.00 instead of $625.00. Use what was paid: $2,000.00 − $700.00 = $1,300.00 due at 80 guests.

If the new total falls below what's been paid

Now say the event shrinks to 20 guests: 20 × $25.00 = $500.00, with $625.00 already paid. That's $125.00 more than the new total. Square's pages don't say what an edit does here. Its deposit article describes refunding a partial payment on an invoice that isn't fully paid only by canceling the invoice first, after which the partial payments show in sales reports as a custom amount. That's a different operation from a headcount change, with its own reporting effect.

So don't edit, cancel or refund just to make this case fit. Check what your event agreement says about the deposit and the final count first. The private-event minimum spend guide covers putting a final guest-count date and deposit terms in writing. Then ask Square support how to handle the invoice before you change it.

What not to do

• Don't use Edit > Deposit to make the balance come out right. It changes the deposit request, not the items or the money collected.
• Don't cancel and re-invoice, or duplicate the invoice and charge again. Duplicate is an ordinary menu action, but the only use Square's troubleshooting article gives it is resending an invoice Square itself canceled after too many failed payment attempts. Nothing in the deposit article points to it for a headcount change.
• Don't ring the balance as a separate sale while the invoice stays open. That's how the 2018 seller ended up trying to clear a balance off an invoice that still held a $400 deposit.
• Don't change the recorded paid amount, or record a payment that didn't happen, to make the numbers match. If the numbers don't match, that's the signal to stop.

Copy this headcount-change check

One per invoice. Use an event reference, not guest names or card details. Any line that comes out "no" where it says STOP means don't save, send, cancel, duplicate, refund or recharge. Take the numbers to Square support.
