SMS payment reminder templates that get invoices paid (and the rules per country)

Below is a full escalating sequence you can copy, plus a per-market quick-table so you know the rule that applies before you hit send.

SMS payment reminder examples (a copy-paste sequence)

Replace the fields in braces with your own details. Keep the message tight so it lands as a single SMS segment. The character count under each one assumes short, real-world values in the merge fields.

Hi {FirstName}, quick heads-up that invoice {InvoiceNo} for {Amount} is due {DueDate}. Pay in a tap here: {PayLink}. Thanks, {BusinessName}.

Hi {FirstName}, invoice {InvoiceNo} for {Amount} is due today. You can settle it here: {PayLink}. Any questions, just reply. {BusinessName}

Hi {FirstName}, invoice {InvoiceNo} ({Amount}) is now a few days past due. If it is already on its way, thank you. If not: {PayLink}. {BusinessName}

Hi {FirstName}, we have not received payment for invoice {InvoiceNo} ({Amount}). Can you confirm a date, or pay now here: {PayLink}? Thanks, {BusinessName}

Hi {FirstName}, invoice {InvoiceNo} is 10 days overdue and a late fee of {FeeAmount} now applies, per our terms. Balance is {Amount}: {PayLink}. {BusinessName}

Hi {FirstName}, invoice {InvoiceNo} ({Amount}) is now 14 days overdue. Please arrange payment within 7 days to keep the account clear: {PayLink}. {BusinessName}

Hi {FirstName}, if paying {Amount} in one go is tricky right now, we can set up installments. Reply YES and we will send a plan, or pay here: {PayLink}. {BusinessName}

Hi {FirstName}, invoice {InvoiceNo} ({Amount}) is 21 days overdue. Without payment or a plan by {ActionDate}, the account moves to our next recovery step. Pay: {PayLink}

Hi {FirstName}, this is a final reminder on invoice {InvoiceNo} ({Amount}), now 30 days overdue. Please pay by {ActionDate} to avoid escalation: {PayLink}. {BusinessName}

Thanks {FirstName}, payment for invoice {InvoiceNo} is in and the account is clear. We appreciate it. {BusinessName}

How to word a payment reminder text

Five things belong in almost every reminder:

• Who you are. A number from an unknown sender gets ignored. Put your business name in the message so the recipient knows this is real.
• The specifics. Invoice number, amount owed, and due date. Vague texts get vague responses.
• A payment link. The whole point of SMS is that it is on the phone already. A tappable link removes the gap between reading and paying.
• The next step. Early on that is "reply if anything is unclear." Later it is a date and what happens after it. State it plainly and never threaten.
• An opt-out. Depending on your market and message type, you may need to include a way to stop the texts. More on that below.

The ladder above moves from a friendly nudge to a factual notice, and the next section shows how to keep each rung polite. For the email versions of the same sequence, see our email templates for invoice payment reminders.

What is a polite way to ask for payment by text?

Four habits keep the ask polite at every rung of the ladder. Messages 2, 3, 4 and 9 above use them.

• Ask, then give the way to say yes. Message 4 asks "Can you confirm a date, or pay now here: {PayLink}?", a request with a route attached.
• Assume it slipped through. Message 3 says "If it is already on its way, thank you", which lets the customer pay without awkwardness.
• Name the date. A specific day to pay by is clearer and kinder than "as soon as possible". Message 9 asks for payment "by {ActionDate}".
• Leave room to answer. Message 2 ends "Any questions, just reply" so a customer with a question can tell you.

When to send SMS versus email

SMS gets read because it is intrusive. Open rates are high precisely because a text pushes its way onto the lock screen in a way an email does not. That intrusiveness is a tool, and like any tool it is easy to misuse.

Send a stranger a firm text about money before you have emailed them, and you look aggressive. Send it after two emails they ignored, and it reads as a reasonable escalation. So the rule we give our own customers is simple: email carries the early, routine reminders; SMS enters when email has been ignored, when the amount is material, or when the due date has clearly passed.

Two more limits. SMS has no room for nuance, so it is the wrong channel for a real dispute over a line item or a delivery. Move that to a call or email. And SMS costs money per message where email usually does not, so spending it on customers who always pay on time is waste. That is why we route by customer group rather than blasting everyone. You can read how the two channels combine on our email and SMS reminders page.

What happens when a customer replies to a payment text?

Several templates above invite a reply, such as "Any questions, just reply" in message 2 and "Reply YES" in message 7. Read each reply that day. If it gives a payment date, note it on the invoice. If it disputes the invoice, hand it to a person, as in handling a disputed invoice. For the full list of reply types, see what to do when a customer replies to a payment reminder.

Reminders can also go out on WhatsApp, and customers can reply there. Their reply lands in Paidnice too. See WhatsApp payment reminders, or the WhatsApp payment reminder message templates.

Which SMS reminder approach fits your business?

Who you text decides when SMS earns its place in the sequence.

SMS reminder compliance by country

This is general information, not legal advice. The rules below apply differently depending on whether a message counts as marketing or as a transactional reminder to an existing customer, and they change over time. Confirm your position with the named regulator or a qualified adviser.

Character limits and cost

Standard GSM encoding gives you 160 characters per segment. Add an emoji or certain special characters and the limit drops to 70 because the whole message switches to a wider encoding. Long links eat into the count too, so use a short pay link where you can. The templates above are built to sit inside one segment once your merge fields are filled with real values.

On cost: with Paidnice, SMS reminders are priced from US$0.10 each (rates vary by currency and destination). Paidnice SMS has no country allow-list: it attempts any number that parses as a valid mobile and routes by country code, with dedicated sending routes for the United States (a toll-free number), the United Kingdom, Australia and New Zealand, and a US long code everywhere else. Each message is capped at 320 characters. A late payer earns the full ladder; a customer who always pays on time gets left on email.

How to automate the sequence

Doing this manually does not scale. You would have to watch every due date, remember which customer is on which rung, and stop the moment a payment lands so nobody gets a "final notice" for an invoice they already settled. That last one is the mistake that costs you a customer.

Paidnice sits on top of Xero and QuickBooks and runs the whole sequence for you: it reads your invoice due dates, sends each reminder on schedule by email, SMS or WhatsApp, applies your late fees and interest at the rung you choose, and stops automatically when Paidnice sees the invoice marked paid. You set the wording and the timing once. It routes VIP customers to a gentle nudge and repeat late payers to the full ladder, so the firm messages only reach the accounts that have earned them. Customers see half as many late invoices in the first 30 days, and 8 in 10 invoices are paid within the first 60 days of using Paidnice.
