How to chase overdue invoices without losing the customer

Why owners don't chase (and why customers don't pay)

Most late invoices aren't disputes. The customer liked the work. They just got busy, lost the email, or figured they'd "get to it Friday." Meanwhile the owner doesn't follow up because it feels awkward — you just spent two days in this person's home or under their car, and now you're supposed to ask them for money like it's a favour?

Reframe it: a reminder isn't a confrontation. It's admin. Done early and lightly, it reads as professionalism, not desperation. Done late and angry, it damages the relationship and still might not get you paid. The trick is a fixed ladder you follow every time, so no single reminder carries emotional weight.

The polite ladder: day 1, day 3, day 7

"Day" here counts from when the invoice goes overdue — if your terms are due-on-receipt, day 1 is the day after the job. Copy these word for word and swap in your details.

Day 1 — the nudge (assume they forgot)

Text: "Hi [name], [your name] from [shop]. Just a heads-up that invoice #[number] for $[amount] went out [yesterday/Tuesday] — here's the link to pay by card if that's easiest: [link]. Thanks again for the work!"

Tone target: you're doing them a favour by resending the link. No mention of "overdue" or "late." Most invoices die right here — roughly half of late payers respond to the first nudge within a day or two.

Day 3 — the check-in (assume something's unclear)

Text: "Hi [name], checking in on invoice #[number] ($[amount]) — did the link come through okay? Happy to resend it or take a card over the phone if that's easier."

This one does two jobs. It removes every practical excuse (lost link, wrong email, prefers phone) and it invites them to tell you if there's actually a problem. If they reply "can we talk about the bill," that's good news — a conversation beats silence every time.

Day 7 — the direct one (assume it's a choice now)

Text: "Hi [name], invoice #[number] for $[amount] is now a week past due. If there's an issue on your end, tell me and we'll sort it out. Otherwise I need it settled by [day, date] — here's the link again: [link]."

Still polite, but three things changed: the word "due" appears, a deadline appears, and the tone is from a business, not a buddy. Most customers pay here because the social contract is now explicit.

After day 7: escalate the channel, not the temperature

If day 7 passes with silence, switch from text to a phone call — scripts in a text thread are easy to ignore, a voice isn't. Keep it short: "Not chasing you to be a pain, I just need to know if we're sorting this or if there's a problem." If that fails, your options are a formal letter, a collections service (they take a cut, typically 20–35%), or small claims court (Ontario's limit is $35,000, and the filing is designed for self-representation). For most shop invoices under a few thousand, the call plus a firm written deadline resolves it before any of that.

Rules that keep you out of trouble

• Always include the payment link in every message. Every extra step between the reminder and the payment is a leak.
• Never apologize for asking. "Sorry to bug you" teaches the customer that your invoice is optional.
• Same ladder for everyone. Friends, regulars, new customers. Consistency is what makes it feel like admin instead of accusation.
• Prevention beats chasing. Card-on-file for repeat customers, deposits on big jobs, and invoices sent the same day the work finishes all shrink the pile before the ladder is even needed.

The version where you never send these texts

The ladder above works. It also requires you to remember which invoice is on which day, for every customer, forever — which is exactly the kind of task that dies the week you get busy. This is one of the first things shops automate: the invoice goes out with a pay link, the day 1/3/7 reminders fire on schedule with your wording, replies land with you, and the ladder stops the moment the payment clears. The customer experiences a polite, professional business. You experience money showing up without a single awkward conversation. It's included in Apex plans from $149/mo — or start with the free Starter app, which at minimum puts a pay link and HST math on every invoice so the chase starts from a better place.
