Send invoice by text: consent, wording and link safety

To send invoice by text the right way, get the client’s permission to message that number, name yourself, the invoice number, the amount and the due date in a short message, link to the full invoice, and include an opt-out. Keep the full invoice as your record.

This is general information, not legal or tax advice.

Why people send invoices by text

Most invoices still travel by email. That works for office clients, and it fails for the plumber’s customer who never opens a work inbox, or the landscaping client who reads messages on a phone between meetings. A text arrives where the client already is. It is short, it is hard to miss, and a payment link inside it turns “I’ll pay that later” into a thirty-second job.

Speed is the real reason. An invoice sent while the work is fresh gets paid sooner than one sent a week later, and a text removes the extra steps: no attachment to open, no PDF viewer, no logging in. For small jobs under a few hundred dollars, that convenience is often the difference between paid this week and paid next month.

Texting also has costs. It is more personal, so a careless message feels pushy. It is easier to ignore a rule you did not know existed. And the message is not the invoice. The rest of this guide covers how to do it properly.

Get consent before you send the first text

Text messages are regulated more tightly than email in the United States, mainly under the Telephone Consumer Protection Act (TCPA) and the rules the Federal Communications Commission (FCC) writes to carry it out. You do not need to read the statute to work safely. You need a simple habit: ask first, record the answer, and honor a “no.”

What counts as a good consent record

A good record answers four questions: who agreed, to what, at which number, and when. Any of these work:

• A signed estimate or contract with a line such as “I agree to receive invoices and payment links by text at the number below.”
• An email reply from the client saying “yes, text me the invoice at this number.”
• A form on your website with a clear checkbox that is not pre-ticked.
• A message thread where you asked and they answered yes.

Save a screenshot or a copy next to the client’s file. If a dispute ever comes up, a dated record is far more useful than your memory.

Transactional versus marketing texts

Regulators treat a text that is part of a transaction the client asked for differently from a promotional text. An invoice for work the client ordered is closer to the first. A message that says “10% off your next visit, book now” is marketing, and marketing texts sent with automated tools generally require a stricter, written form of consent. The line between the two depends on the facts, and a single message that mixes an invoice with a promotion can be treated as marketing. Keep invoice texts about the invoice.

If you send texts using software or a platform that sends them automatically, assume the stricter side of the rules applies and get written consent. If you are unsure which category you are in, ask a lawyer who handles telecom or consumer protection law. This guide cannot make that call for you.

Opt-out rules you should follow

Every recipient must be able to say stop, and you must listen.

In its 2024 final rule on consent revocation, the FCC said people can revoke consent to robocalls and robotexts in any reasonable way that clearly shows they no longer want them. Replying with words such as stop, quit, end, revoke, opt out, cancel or unsubscribe counts as a reasonable method. The rule also says a reply in other words must be honored if a reasonable person would understand it as a request to stop. The FCC’s 2024 order also set a maximum of 10 business days to honor a request. Parts of that order, including the revocation provisions, had their effective dates delayed, so check the FCC’s current status before you rely on a specific deadline. Do not treat the delay as permission to keep texting someone who has asked you to stop.

Practical rules that hold up either way:

• Put “Reply STOP to opt out” in the first text to a new number, and in any message that goes out repeatedly.
• Treat any plain-language “stop” as a stop, even if it is not your keyword.
• Stop right away, not after ten days, and log the date and number.
• If you send from a number that cannot receive replies, say so in the message and give another way to opt out, such as an email address.
• After an opt-out, send invoices by email or mail. Do not text to ask them to reconsider.

An opt-out from invoice texts does not cancel the debt. The invoice is still due. You just need another channel to collect.

Message wording that works

A good invoice text is short, specific and sounds like a person. It tells the client who you are, what the message is about and what to do next. Here are three templates you can adapt.

First invoice to a client who agreed to texts

Hi Dana, this is Marco from Marco Plumbing. Thanks for today. Invoice INV-0142 for $445.00 is due Nov 7. View and pay: [link]. Reply STOP to opt out.

Short reminder, a few days before the due date

Hi Dana, a friendly reminder that INV-0142 ($445.00) is due Nov 7. Pay or view it here: [link]. Questions? Call me at [number].

Follow-up after the due date

Hi Dana, INV-0142 for $445.00 was due Nov 7 and is still open. If you have already paid, thank you, and tell me so I can update my records. Otherwise you can pay here: [link].

Notice what each message does:

• It names the sender, so the client knows it is not spam.
• It includes the invoice number and amount, so the client can match it to the job.
• It gives one link and one call to action.
• It avoids threats, shaming and urgency tricks. Those turn a paid invoice into an argument.

Link safety: how to make a payment link trustworthy

Clients get scam texts every week, many of them pretending to be a bill. A real invoice has to look different from those, and you can help.

• Use a link to a page you control or a payment provider the client can recognize. Avoid link shorteners that hide the destination.
• Name yourself and the job in the text. “Invoice INV-0142 from Marco Plumbing” is easy to check. “You have a pending payment” is not.
• Tell clients how you will and will not ask. A line in your estimate such as “We send invoices by text from this number and will never ask for card details by reply” is cheap protection.
• Never ask for card numbers, bank logins or one-time codes in a reply. Payments belong on a secure page, not in a chat.
• Send from one consistent number. A client who has saved your number will trust a text from it.
• Make the page show the same details as the text. If the text says $445.00 and the page shows $445.00 under your business name, the client can confirm they match.
• Expire or limit links where you can, so an old link forwarded by accident does not stay live forever.

If a client says the text looks suspicious, thank them. Offer to email the invoice or read the invoice number over the phone.

When text beats email, and when it does not

Neither channel wins every time.

Situation	Better channel	Why
Small job, client on their phone	Text	Faster to open and pay
Client’s accountant needs the PDF	Email	Easy to forward and file
Large invoice or long project	Email, with a text nudge	Paper trail plus attention
Client has opted out of texts	Email or mail	Respect the opt-out
Overdue invoice	Both, in order	Text first, email for the record
Client who replies to nothing	Phone call	A voice often works when text fails

Email has its own rules, including the FTC’s CAN-SPAM requirements for commercial messages. It is still good practice to send invoice emails from a real address and make them easy to reply to. Whichever channel you use, send the same invoice with the same number so your records match. If you need a refresher on the basics, read how to send an invoice.

A checklist before you text an invoice

Common mistakes

• Texting a number you found, not one the client gave you. The number may belong to someone else.
• Mixing a promotion into an invoice text. Keep the message about the bill.
• Sending a link with no context. A bare link looks like a scam.
• Texting at odd hours. A message at 11 pm feels like pressure. Send during normal hours.
• Ignoring a stop request because the invoice is overdue. The debt remains. Your right to keep texting does not.
• Treating the text as the record. Keep the invoice itself, including the tax lines, for your books.

Where PayToMe fits

Text-to-pay is in development. The plan is to let you send an invoice by text with a secure pay link, and to keep consent and opt-out handling in one place, with nothing sent until you confirm. You can read the plan on the text-to-pay invoices page. Today PayToMe is in public beta: you can send invoices by email with a public pay link, and the free invoice generator creates the invoice itself, so you can pair either with the habits above. Sign in to PayToMe.
