How to Collect Unpaid Invoices Faster: A Contractor's Get-Paid Playbook. Maximus, the AI operations manager for home services.

This is the leak that stings the most, because you already earned the money. The tech showed up. The job got done. And the cash is sitting in someone else's account because nobody chased the invoice. Ellen Rohr says it plainly: cash flow is not profit. A profitable shop can still run out of money when receivables age past 30, 60, and 90 days.

The good news is this is the easiest leak to plug, because you are not selling anything new. You are finishing the job you already did. Here is the playbook we use.

Why do home services invoices go unpaid?

Most home services invoices go unpaid for one of three reasons: the customer was never asked to pay at completion, no reminder ever went out, or the invoice was confusing. It is rarely that the customer cannot pay. It is that nobody made paying easy and nobody followed up.

The pattern is almost always a process gap, not a deadbeat customer. The job wraps, the tech leaves, the invoice goes out days later, and then it sits because the office is buried. The longer it sits, the harder it gets to collect. That is the whole problem in one sentence.

How long should you wait before chasing an invoice?

You should not wait at all. The best time to collect is at the moment the work is done, on-site, before the tech leaves. After that, every day you wait makes the money harder to get. An invoice chased on day 3 collects far more reliably than one chased on day 45.

The math is brutal and simple. Collection rates drop the longer an invoice ages. So the goal is not better debt collection. It is collecting before the invoice ever becomes "old."

How to collect unpaid invoices faster, step by step

The fastest way to collect is to make paying effortless and to follow up on a fixed schedule instead of when you remember. Here is the cadence that works for home services.

WhenAction
At job completionCollect on-site. Tech sends a payment link from the field.
Same dayEmail the invoice with a one-click pay link, not a PDF they have to mail a check for.
Day 3Friendly text: "Hi [name], just confirming you got the invoice for [job]. Here's the link to pay: [link]."
Day 7Second reminder, still warm.
Day 14Direct reminder with the due date and the amount, by text and email.
Day 30Phone call. Polite, firm, specific.
Day 45+Escalate per your policy.

Three rules make this work. Make it one click to pay. Keep the early reminders warm, not threatening. And never let a reminder depend on someone remembering to send it. The shops that get paid fast are not tougher. They are more consistent.

How much is aging AR costing you?

Aging accounts receivable costs you the use of your own money and the slice you will never collect at all. Every dollar stuck in a 60-day invoice is a dollar you cannot use to make payroll, buy a truck, or take on the next job. And a percentage of aged invoices simply never get paid.

Run your own number: pull your receivables over 30 days and add them up. That is cash you earned and cannot touch. For most shops it is more than they expect, and it is the cheapest money to recover because the work is already behind you.

The number to watch is your average days-to-collect. Post it where you can see it. What gets measured gets paid faster.

How to get paid without chasing at all

The best version of this is to never chase an invoice yourself. Maximus sends the invoice the moment the job is done, includes a one-click payment link, runs the reminder cadence automatically by text and email, and flags the ones that need a real phone call. He runs $497 a month, or 8 percent of the revenue he recovers, whichever is higher.

He is the part of the office that never forgets to follow up and never feels awkward asking for money. He sits on top of the tools you already run, syncs with your invoicing, and reports every morning on what got collected and what is still out. Hiring a person to do this is one option (see what an office manager costs); putting it on autopilot is another.

He chases the money. You stay on the truck.

Frequently asked questions

How do I get a customer to pay an overdue invoice? Make paying one click, follow up on a fixed schedule (day 3, 7, 14, then a call at 30), and keep the early reminders friendly. Most overdue invoices get paid once paying is easy and someone consistently follows up.

When should I send the first invoice reminder? Within a few days of the invoice, not weeks later. Collection rates drop the longer an invoice ages, so early, warm reminders collect far more than late, stern ones.

Should I charge a late fee on unpaid invoices? A late fee can help if it's stated up front on the invoice and your terms. But for most home services shops, faster and more consistent follow-up recovers more than penalties do.

How can I collect invoices without chasing customers myself? An AI operations manager like Maximus sends the invoice, includes a pay link, and runs the reminder cadence automatically for $497 a month or 8 percent of recovered revenue, flagging only the ones that need a human call.

What's a healthy days-to-collect for a contractor? The faster the better. Collecting at completion is ideal. If much of your AR is aging past 30 days, that's a process gap worth fixing before it becomes uncollectable.

When should I send an unpaid invoice to a collections agency? Only after your own reminders, a phone call, and a final notice have failed, usually once an invoice is 90 or more days past due. Agencies take a large cut, so it is a last resort. Most invoices get paid first if you follow up early and consistently.

What are my legal options if a customer won't pay? Options include a formal demand letter, small claims court for smaller amounts, or a lien where your trade allows it. These are last resorts, and this is not legal advice, so check your state's rules. Most unpaid invoices never get that far if you chase them early.
