Partial payment: meaning, invoice example, journal entry and receipt
A partial payment is a payment that covers only part of the amount due on an invoice or account; the rest stays open as the customer's balance due. For a small business it is everyday life — a customer pays half now and half at month-end, sends a deposit before work starts, or pays what they can on an overdue account. The money is easy to take; the trouble starts later, when nobody remembers which invoice it was for. Below: how to show a partial payment on an invoice, the journal entries for both sides, deposits vs partial payments, how to apply one payment to several invoices with a worked ledger, a partial payment receipt and acknowledgement letter you can copy, a simple payment plan agreement, and the "paid in full" check you should not cash without thinking — plus how to record it all on the customer's account in Account Ledger by Ofisx.
Short answer
- Partial payment meaning: a payment that is less than the full amount due; the unpaid part remains owed as the balance due.
- On the invoice: show Invoice total, Amount paid (with date and method) and Balance due — never overwrite the original total.
- Seller's journal entry: Dr Cash / Cr Accounts Receivable for the amount received. Buyer: Dr Accounts Payable / Cr Cash.
- Deposit vs partial payment: a deposit is paid before the invoice or delivery (a liability until earned); a partial payment is paid against an invoice already issued.
- Several open invoices: apply the payment to the invoice the customer names; if they name none, the usual practice is oldest invoice first — and tell the customer how you applied it.
- Careful: a check marked "payment in full" for less than a disputed balance can settle the whole debt in many states if you cash it — talk to a lawyer before depositing it.
When partial payments happen
| Situation | Example | How to record it |
|---|---|---|
| Agreed split payment | 50% on delivery, 50% within 30 days | Invoice the full amount; record each payment against it |
| Deposit before work or delivery | 30% deposit on a $5,000 custom order | Customer deposit (liability) until the invoice is issued, then applied to it |
| Progress (milestone) billing | Contractor bills per stage of a job | Separate invoice per stage, or one invoice with payments by stage |
| Customer short on cash | Pays $1,200 of a $3,200 invoice | Partial payment; agree the date for the rest in writing |
| Short payment for a reason | Customer pays $300 less because of damaged goods | Record the payment; settle the difference with a credit memo or chase it |
| Payment plan on an overdue account | Monthly payments on a past-due balance | Each payment reduces the balance; for larger sums use a promissory note |
Partial payment invoice example
Northside Building Supply invoiced Brookside Contractors $3,200.00 on November 5, 2026, Net 30. Brookside paid $2,000.00 on November 25. The updated invoice (or the next statement) shows:
| Line | Amount |
|---|---|
| Invoice INV-1101 — November 5, 2026 — due December 5, 2026 | |
| Invoice total | $3,200.00 |
| Less: payment received November 25, 2026 — ACH ref. 88412 | −$2,000.00 |
| Balance due by December 5, 2026 | $1,200.00 |
Keep the original invoice number and total; add the payment as its own line with date and reference. Most invoicing tools mark such an invoice "Partially paid". The due date does not move unless you agree a new one — a partial payment is not an extension.
Partial payment journal entry
| Event | Debit | Credit |
|---|---|---|
| Seller: invoice issued (Nov 5) | Accounts Receivable — Brookside $3,200.00 | Sales Revenue $3,200.00 |
| Seller: partial payment received (Nov 25) | Cash $2,000.00 | Accounts Receivable — Brookside $2,000.00 |
| Buyer: partial payment made (Nov 25) | Accounts Payable — Northside $2,000.00 | Cash $2,000.00 |
| Seller: deposit received before invoicing | Cash $1,500.00 | Customer Deposits (liability) $1,500.00 |
| Seller: invoice issued, deposit applied | Accounts Receivable $3,500.00; Customer Deposits $1,500.00 | Sales Revenue $5,000.00 |
A partial payment does not create new revenue — the sale was already recorded when you invoiced. It only turns part of the receivable into cash. A deposit is different: until you deliver, it is money you owe back, so it sits in a liability account. Your accountant may use other account names; the direction of the entries is what matters.
How to apply a partial payment to several invoices
Brookside has two open invoices and pays twice. With no instructions from the customer, Northside applies each payment to the oldest invoice first:
| Date | Description | Charges | Payments | Balance | Applied to |
|---|---|---|---|---|---|
| Nov 5, 2026 | Invoice INV-1101 (due Dec 5) | $3,200.00 | $3,200.00 | ||
| Nov 19, 2026 | Invoice INV-1126 (due Dec 19) | $1,500.00 | $4,700.00 | ||
| Nov 25, 2026 | Payment — ACH 88412 | $2,000.00 | $2,700.00 | INV-1101 ($1,200.00 left) | |
| Dec 10, 2026 | Payment — check 2207 | $1,800.00 | $900.00 | INV-1101 $1,200.00 (closed) + INV-1126 $600.00 ($900.00 left) |
Brookside owes $900.00, all on INV-1126, due December 19. Note that INV-1101 was paid 5 days late — that shows up in an aging report only if you apply payments to invoices, not just to the total. If the customer writes an invoice number on the check or remittance, follow it. A running-balance client ledger plus a monthly statement of account lets the customer see the same picture.
Partial payment receipt and acknowledgement letter
Give a receipt for every partial payment. It should say what was received, what it was applied to and what is still owed:
- Receipt no. and date: R-0533 — December 10, 2026
- Received from: Brookside Contractors LLC
- Amount and method: $1,800.00 — check no. 2207
- Applied to: INV-1101 $1,200.00 (now paid in full); INV-1126 $600.00
- Balance remaining: $900.00 on INV-1126, due December 19, 2026
- Statement: "This is a partial payment. Acceptance does not waive the remaining balance."
- Received by: name and signature
Acknowledgement letter you can adapt: "Dear Ms. Patel, thank you for your payment of $1,800.00 by check no. 2207 received on December 10, 2026. We applied $1,200.00 to invoice INV-1101, which is now paid in full, and $600.00 to invoice INV-1126. The remaining balance of $900.00 on INV-1126 is due on December 19, 2026. Accepting this partial payment does not waive the remaining balance. Please contact us if your records differ. — Northside Building Supply, Accounts Receivable."
Partial payment agreement (payment plan) template
When a customer asks to pay an overdue balance in parts, put these points in a short signed letter or email both sides confirm:
- The total balance agreed (after any credits), with the invoice numbers it covers.
- The amount and date of each payment — e.g. $500.00 on the 1st of January, February and March 2027 and $300.00 on April 1, 2027.
- Whether a late fee or interest applies, and that new orders are on cash terms (or within a set limit) until the plan is finished.
- What happens if a payment is missed: the whole remaining balance becomes due.
- That the agreement does not waive any part of the balance.
- Signatures (or written confirmation) of both parties.
- For larger amounts, or when you want an enforceable schedule with interest, use a promissory note instead.
The "paid in full" check trap (accord and satisfaction)
If a customer genuinely disputes what they owe and sends a check for less, clearly marked "payment in full" or with a letter saying so, cashing that check can in many states settle the entire debt — a rule known as accord and satisfaction (for checks, UCC § 3-311 as adopted by each state). Writing "under protest" on the check does not always protect you.
What to do: if the amount is not in dispute, the rule usually does not apply; if it is, or if you are unsure, do not deposit the check before talking to a lawyer, and answer the customer in writing. Some states have extra rules — for example, allowing the creditor to undo the settlement by repaying the amount within a set time.

The options in detail
Account Ledger by Ofisx
Account Ledger keeps a ledger for each customer and supplier — sales and purchases on credit with a due date, payments, partial payments and returns — and shows each running balance. From the customer's card you can send the balance by WhatsApp or share the ledger as a PDF statement.
It does not issue invoices or receipts, take card payments or post journal entries — write the receipt number in the payment's note so the statement and the receipt match.
Intuit QuickBooks
QuickBooks applies partial payments to specific invoices and marks them partially paid inside full accounting.
Zoho Books
Zoho Books records partial payments against invoices and keeps advances as retainers.
Wave
Wave combines invoicing and bookkeeping for very small businesses.
Spreadsheet
A sheet works while partial payments are rare; the classic mistake is typing the new balance over the old one and losing the payment history.
Partial payment rules that prevent disputes
- Never overwrite the invoice total — Add the payment as a separate line; the history is your evidence.
- Say which invoice it pays — Follow the customer's instruction; otherwise oldest first, and tell them.
- Give a receipt every time — With the amount applied and the balance left.
- A partial payment is not an extension — Agree a new date for the rest in writing, or the original due date stands.
- Keep deposits separate — Money taken before delivery is owed back until you deliver.
- Read the check before cashing it — "Payment in full" on a disputed amount needs a lawyer's view first.
Limits — what Account Ledger does not do
- Account Ledger does not create invoices or receipts, take card or ACH payments, post journal entries or calculate sales tax.
- It does not send automatic email reminder sequences; you send the WhatsApp reminder from the customer's card.
- In the US the app is on the App Store for iPhone; the Android version is on Google Play in Turkey only for now.
- It is a paid subscription after the free trial; the App Store shows current plans and prices.
Frequently asked questions
What is a partial payment?
A partial payment is a payment that covers only part of the amount due on an invoice or account. The unpaid part remains owed as the balance due until it is paid, credited or written off.
How do you show a partial payment on an invoice?
Keep the original invoice total and add a line for the payment with its date and reference, then show the balance due. For example: Invoice total $3,200.00, less payment received November 25, 2026 $2,000.00, balance due $1,200.00 by December 5, 2026.
What is the journal entry for a partial payment?
The seller debits Cash and credits Accounts Receivable for the amount received; the buyer debits Accounts Payable and credits Cash. No new revenue is recorded, because the sale was recorded when the invoice was issued.
What is the difference between a deposit and a partial payment?
A deposit is paid before the invoice or delivery and is a liability (customer deposits) for the seller until the goods or services are delivered. A partial payment is paid against an invoice that has already been issued and reduces accounts receivable.
How do you apply a partial payment to multiple invoices?
Apply it to the invoices the customer specifies. If they do not specify, the common practice is to apply it to the oldest open invoice first and tell the customer how it was applied on the receipt or the next statement.
Does accepting a partial payment waive the rest of the debt?
Normally no — the remaining balance is still owed, and stating that on the receipt helps. The exception is a check clearly marked "payment in full" for a genuinely disputed debt: cashing it can settle the whole debt in many states (accord and satisfaction), so get legal advice before depositing such a check.
What should a partial payment receipt include?
Receipt number and date, who paid, the amount and method, which invoice or invoices it was applied to, the balance still owed with its due date, a line saying the payment is partial and does not waive the balance, and the name or signature of the person who received it.
What is the best way to track partial payments from customers?
Record every payment as its own line on the customer's account with the invoice it applies to, so the running balance and history stay correct, and send a statement each month. Accounting apps such as QuickBooks and Zoho Books apply payments to invoices; Account Ledger by Ofisx keeps each customer's running balance with partial payments, due-date alerts and PDF statements on iPhone, with a free trial and then a subscription.
