Automatic Payment Reminders: How to Set Up a Schedule

Automatic payment reminders are scheduled emails your invoicing software sends about an unpaid invoice, timed relative to its due date. Most late invoices are not refusals. They are invoices that missed a client's payment run, sat in the wrong inbox, or are waiting on a question nobody asked. A reminder that arrives before the payment run, with the amount and a payment link, fixes most of those without you writing a single chase email.

This guide covers the schedule itself, what goes in each message, how the main invoicing tools let you configure reminders, a dated worked example, and the cases where automation should step aside.

What schedule should automatic reminders follow?

Use one reminder before the due date and two or three after it, then switch to a person. That is the shape almost every invoicing tool's settings are built around, and it maps to how clients actually pay: accounts payable teams run payments weekly or twice a month, so a reminder only helps if it lands before the next run.

Two adjustments matter more than the exact day counts:

• Large or enterprise clients: move the heads-up earlier (7 to 10 days before the due date). Their approval chain is longer, and a reminder two days out arrives after the payment file is built.
• Small clients who pay by card: a heads-up 2 or 3 days out is enough, and a due-date email with a payment link often does more than any later reminder.

Cap the automated sequence. Four automated emails on one invoice is plenty; after that, more of the same template reads as noise and a short personal message gets a better response. If you need wording, the payment reminder email templates and payment reminder etiquette guides cover tone in detail.

What should every automated reminder include?

Every reminder should be answerable without opening anything else. The client, or their accounts payable clerk, should be able to pay from the email alone.

• Invoice number in the subject line. "Reminder: Invoice INV-0042, $2,400 due December 2" beats "Following up". AP teams search their inbox by invoice number.
• The remaining balance, not the original total. If the client paid part of it, a reminder for the full amount causes a dispute.
• The original due date and days overdue. Facts, not adjectives.
• One way to pay. A payment link, or your bank details, but one clear call to action.
• The invoice itself. Attach the PDF again or link to where the client can view it.
• An exit for problems. "If anything on this invoice is wrong, reply and we will fix it." That one line surfaces disputed invoices early, when they are cheap to resolve.
• Your payment terms, briefly. If your invoice payment terms include late fees or interest, the final automated reminder is where you restate them.

Leave out threats, all-caps subject lines and new conditions. A late fee that was never in your contract or on the invoice cannot appear for the first time in reminder number three.

How do invoicing tools handle automatic reminders?

Most invoicing and accounting tools include a reminder setting; they differ in how many reminders you get, how flexible the timing is, and whether the settings apply per client or across the whole account. This table summarizes each vendor's own help documentation as of October 2026.

Two differences are worth checking before you rely on a tool:

1. Per-client versus account-wide. FreshBooks lets you set reminders per client. Account-wide settings (InvoiceQuickly's, for example) are simpler but mean a client on special terms gets the same cadence as everyone else, so you would handle that client manually.
2. What happens after a partial or offline payment. A reminder is only as accurate as the payment records. If a client paid by bank transfer and you have not recorded it, the software will keep chasing a paid invoice.

Worked example: one invoice through a reminder schedule

Worked example with stated inputs: a $2,400 invoice (INV-0042) issued Monday, November 2, 2026, on net 30 terms, so it is due Wednesday, December 2, 2026. The business uses a common textbook cadence of 3 days before, then 3, 7, 14 and 30 days after the due date.

Two of the five "standard" dates fall on a weekend and one on a public holiday. Reminder offsets are set in days relative to the due date, so where they land depends on the weekday the invoice falls due. With this 3/3/7/14/30 cadence, a Monday due date always puts every reminder on a weekday (Friday, Thursday, Monday, Monday, Wednesday); here, a due date of Monday, November 30 would have done it. Setting your payment terms so invoices fall due early in the week is often easier than adjusting each reminder.

The same example shows why the sequence should stop on its own. If the client pays $1,200 on December 7 and you record it, the December 9 and December 16 reminders should show a $1,200 balance. If you forget to record it, they still say $2,400, and your next email is about a dispute you created.

When should automatic reminders stop?

Stop or pause the sequence whenever a human conversation has started. Automation is for invoices nobody is talking about.

• The client disputes the invoice. Pause, resolve, then reissue or correct it. An automated "friendly reminder" in the middle of a dispute reads as if nobody read their email.
• The client pays, in full or in part. Record the payment the same day so reminders show the right balance or stop.
• The client asks for a payment plan or an extension. Agree the new date in writing and, if your tool allows, change the due date rather than letting the old schedule run.
• You reach the end of the automated sequence. After the final automated email, pick up the phone or write a short personal note. Escalation options after that are covered in the late payment guide.

Whatever triggers the stop, note it next to the invoice with the date, so your invoice audit trail shows which reminders went out and why the sequence ended.

Can you add late fees or interest to reminders?

Only if they were agreed in advance, and only within the law where you and your client operate. In the US, late-fee rules vary by state; see late fee laws by state for the overview and check your state's statute. The late fee calculator works out simple interest on an overdue amount in your browser.

In the UK, the Late Payment of Commercial Debts (Interest) Act 1998 gives businesses a statutory right to claim interest and fixed recovery costs from other businesses. GOV.UK states that statutory interest is 8% plus the Bank of England base rate for business-to-business transactions, unless the contract sets a different rate, and that a payment is late 30 days after the customer receives the invoice if no date was agreed. Section 5A of the Act sets fixed recovery sums of £40 for debts under £1,000, £70 from £1,000 to under £10,000, and £100 for £10,000 or more.

Worked example (UK, B2B, illustrative base rate): £2,400 paid 30 days late, assuming a 4% base rate for the calculation. Statutory interest is 12% a year: £2,400 × 12% = £288 a year, about £0.79 a day, so roughly £23.67 for 30 days. Add the £70 fixed sum for a debt between £1,000 and £10,000. Check the Bank of England base rate that applies to your debt, using the GOV.UK guidance, before you claim.

Mention the right to claim in your terms from day one and in the final automated reminder, not in the first friendly one.

How do you measure whether reminders are working?

Track three numbers for a few months before and after you change the schedule:

1. Average days from due date to payment, per client. If one client always pays 12 days late regardless of reminders, their payment run is the constraint; move their heads-up earlier or change their terms.
2. Share of invoices paid after reminder 1 or 2. If almost nothing is paid until a personal call, your automated emails are being filtered or ignored. Check the subject line and the sender address.
3. Disputes raised by reminders. If reminders keep surfacing wrong amounts or wrong contacts, fix the invoicing step, not the reminder.

If you send most invoices in one month-end batch, every reminder in the sequence also fires in a batch. Spreading issue dates across the month spreads the follow-up work too.

Days sales outstanding is the business-wide version of the first number. If an early-payment discount is on the table, model it first with the discount calculator.

How InvoiceQuickly handles reminders

InvoiceQuickly's automatic reminders are part of the Pro plan ($9/month); the Free plan does not send emails or reminders. On Pro you turn reminders on in your account settings and choose:

• how many days before the due date the "due soon" reminder goes out,
• how long after the due date overdue reminders start,
• how many days apart overdue reminders repeat, and
• the maximum number of reminders per invoice (the "due soon" email counts toward it).

Reminders are scheduled before and after the due date and stop once an invoice is marked paid or cancelled. Each one shows the remaining balance after any recorded payments, and links to the client's private portal and to the invoice's Stripe or PayPal payment link if you have added one. The settings apply to every invoice in the account; there is no per-client cadence, so clients on special terms need a manual note. If you only need wording, the free payment reminder templates give you three copy-ready emails (gentle, firm and final) with no account.

When automatic reminders are the wrong tool

• Large clients with formal AP portals. If invoices must be uploaded to a supplier portal or matched to a purchase order, a reminder email to your contact rarely moves the payment. Ask the AP team for the payment-run calendar and the PO status instead.
• Clients you speak to every week. For a close retainer client, a templated reminder can feel colder than a one-line message from you. Turn reminders off for that relationship, or handle it manually if your tool is account-wide.
• Invoices you already know are disputed. Automation cannot negotiate.
• Very low volume. If you send three invoices a month and know each client, a calendar note may be all you need.

Frequently asked questions

How many payment reminders should you send?

Three to five in total: one before the due date and two to four after it, spaced about a week apart, followed by a personal call or email. Built-in limits are in the same range: QuickBooks Online and FreshBooks offer three automatic reminders and Xero up to five.

Should you send a reminder before the invoice is due?

Yes, for most business clients. A heads-up 3 to 7 days before the due date gets the invoice into the client's next payment run, which is when most "late" invoices are actually missed. Keep it short and informational, with the amount and a payment link.

How do I politely ask for an overdue payment?

State the facts and make paying easy: the invoice number, the remaining balance, the original due date and a payment link, plus an offer to fix anything that is wrong. Assume an oversight in the first overdue reminder and save firmer wording, including any late-fee terms, for later ones.

Is there a way to automate invoices and reminders together?

Yes. Most invoicing tools combine recurring invoices with reminder schedules, so a monthly invoice is generated and then followed up automatically if it is not paid. See the recurring invoices guide for how recurring billing works and what to check before turning on automatic sending.

Do automatic reminders stop when the client pays?

They stop when the software knows the invoice is paid. Online payments through a connected processor usually update the invoice automatically; bank transfers, cash and checks have to be recorded by you. Record payments the same day to avoid chasing a client who has already paid.

Can I add a late fee in an automated reminder?

Only if the late fee was in your contract or on the original invoice, and it complies with the law where you operate. A reminder can restate an agreed fee, but it cannot introduce a new one. In UK business-to-business sales, GOV.UK says you can claim statutory interest and fixed recovery costs on late payments unless your contract sets a different rate.

Are automatic reminders annoying to clients?

Not when they are factual, spaced out and stop once the invoice is paid or disputed. Clients get annoyed by reminders for invoices they already paid, reminders with the wrong amount, and daily emails. Accurate payment records and a capped sequence prevent all three.
