Email invoice reminders get buried. BillMate, a UK multi-business invoicing platform, added Team-Connect SMS so a payment reminder lands where customers actually read it, on their phone. Here is how the setup works in practice.
BillMate is an invoicing and quoting platform for UK sole traders and small businesses. Users raise invoices and quotes across multiple businesses from one account, take card payments online, and reconcile against their bank feed. Like every invoicing tool, its users share one universal frustration: getting customers to actually pay on time.
The gap was never raising the invoice. It was the follow-up. A reminder emailed to a customer sits in a crowded inbox next to newsletters and receipts, often unopened for days. The invoice is not disputed, it is simply not seen. That delay is what pushes a 30-day invoice out to 45 or 60.
Late payment is a cash-flow problem before it is anything else. A small business waiting on a handful of overdue invoices can find itself unable to pay its own suppliers, not because the money is not owed, but because the reminder never reached the top of the pile. Email open rates make this worse: a chase email competes with everything else in the inbox and is easy to postpone.
BillMate wanted a reminder channel with a much higher chance of being seen quickly, without asking users to pick up the phone and have awkward conversations chasing money.
BillMate connected Team-Connect so that payment reminders can be sent by text message alongside email. The mechanism is deliberately simple, because reminders about money need to feel factual and calm, never like marketing.
On the day an invoice falls due, the customer gets a short text with the business name, the amount, and a link to pay. It arrives as a helpful prompt, not a demand.
If the invoice is still unpaid a few days later, a second, firmer reminder goes out, again with the amount and the payment link, so paying is one tap away.
Every reminder carries a direct link to settle the invoice, removing the friction of the customer having to find the original email or log in anywhere.
Once an invoice is marked paid, the reminder sequence stops automatically, so no one is ever chased for money they have already sent.
Text messages are opened far more reliably, and far sooner, than email. For a payment reminder that matters enormously: the whole job is to get the invoice back in front of the customer at the moment they can act on it. A reminder that is read within minutes of arriving is a reminder that gets paid, and because the payment link is right there in the message, seeing it and settling it happen in the same action.
Just as important, SMS keeps the tone light. A short, factual text reads as an administrative nudge rather than a confrontation, which means BillMate users can chase payment consistently without straining the customer relationship.
Payment reminders to a customer about an invoice they owe are transactional service messages, not marketing, so they sit outside most PECR marketing-consent rules. Every BillMate reminder identifies the business sending it, states the amount and reference clearly, and gives the customer an easy way to reply or query. That is the line between a legitimate reminder and a nuisance, and it is built into how the messages are written.

You do not need to be an invoicing platform to send payment reminders by text. Any UK business that raises invoices can use the same approach with Team-Connect: automated, factual reminders with a pay-by-link, that stop as soon as the invoice is settled.
Yes. Because text messages are opened far more reliably than email, a short payment-reminder SMS puts the invoice in front of the customer where they will actually see it. It works best as a polite nudge on or just after the due date, with a clear amount and a link to pay.
Invoice and payment reminders to an existing customer about money they owe are transactional service messages, not marketing, so they sit outside most PECR marketing-consent rules. You still need a lawful basis to hold the number and should always identify your business and keep the message factual.
Keep it short and specific: your business name, the invoice number or amount, the due date, and a way to pay or query it. Avoid pressure or marketing language, and give the customer an easy route to reply or call.
