How to Collect Unpaid Invoices From Customers

Here's how to collect unpaid invoices from customers in a service business. Get paid on site whenever you can. Take deposits on big jobs. Put your payment terms in writing before the work starts. Then follow a set reminder schedule (day 1, 7, 14 and 30) with a card link in every message. Offer a payment plan to people who want to pay but can't do it all at once. Escalate to a collection agency or small claims only after that. And keep one collections list, oldest balance first, so nothing slips. Below is each step, with sample texts you can copy.

How to collect unpaid invoices from customers: start before the job

The easiest invoice to collect is the one that never goes unpaid. Most open balances in field service come from three gaps: the tech left without collecting, the customer didn't know what they owed, or nobody followed up.

Get paid on site

The best time to get paid is when the customer is standing in the kitchen looking at the fixed sink. Give your techs a way to take a card in the field and make it part of the close-out: job done, photos in, payment taken, then drive.

If a tech can't collect (the customer isn't home, or a property manager pays), the invoice should go out the same day, not at the end of the week.

Take deposits on big jobs

For installs, replacements and anything with special-order parts, take a deposit before you order. A common setup is a deposit up front and the balance at completion. The customer has skin in the game, and you're not stuck holding parts you paid for.

Put your terms in writing

Before the work starts, the customer should see in writing:

• What the job costs, or what the estimate covers
• When payment is due (on completion, or within a set number of days)
• How they can pay
• Any late fee, if you charge one and your state allows it

Put this on the estimate and the invoice. When a balance goes late, you'll point back to it.

The reminder schedule: day 1, 7, 14 and 30

People don't pay for two reasons: they forgot, or they don't want to. Reminders fix the first group and sort out the second. Keep every message short, friendly and specific, and include a link to pay by card.

Day 1: the invoice

Hi Maria, thanks for having us out today. Here's your invoice for the water heater repair: $425. You can pay by card here: [link]. Questions? Just reply.

Day 7: the friendly nudge

Hi Maria, quick reminder that invoice #2093 for $425 is still open. Pay by card here: [link]. Thanks!

Day 14: the direct ask

Hi Maria, invoice #2093 for $425 from 9/15 is now two weeks past due. Can you pay by Friday? Card link: [link]. If something's wrong with the bill, call me at [number] and we'll sort it out.

Day 30: the final notice, by email

Subject: Final notice, invoice #2093

Hi Maria,

Invoice #2093 for $425 (water heater repair on 9/15) is now 30 days past due. We've sent reminders on 9/22 and 9/29.

Please pay in full by 10/22 using this link: [link]. If you can't pay all of it at once, call me and we can set up a payment plan.

If we don't hear from you by then, we'll move this to our next step for collecting past-due balances.

Thanks, [Name], [Company], [Phone]

At day 30, also pick up the phone. A call gets answers a text won't.

Make paying easy

Every extra step between "I should pay that" and "paid" costs you money.

• Card links in every reminder. One tap to pay beats "mail a check."
• Several ways to pay. Card, bank transfer (ACH) and check if you take them.
• Know your card fees. As of October 2026, Jobber lists 2.9% plus 30 cents for online card payments and 1% for ACH. Housecall Pro lists 2.99% for online invoice payments and 1% for ACH. Check your own processor's rates and build them into your prices.

Offer a payment plan

Some customers want to pay and can't do it all at once. A payment plan beats a collection agency for both of you.

• Get it in writing: total owed, payment amount, due dates
• Keep the payments short, like 2 to 4 payments
• Take the first payment when you agree to the plan
• If a payment is missed, the reminders start again

When to use a collection agency or small claims

If a customer stops answering after day 30, you have a few options. Rules for each vary by state, so check your local rules or talk to a lawyer before acting. This isn't legal advice.

Collection agency. An agency chases the debt for you, and most take a share of what they collect. Agencies that collect from consumers have to follow federal and state collection laws. This makes sense for balances big enough to be worth sharing and too small to sue over.

Small claims court. You file, the customer gets notice, and a judge decides. The dollar limit, filing fees and process all depend on your state and county. Bring the estimate, the signed work order, photos, the invoice and your reminder history.

Liens. Many states let contractors file a lien on the property for unpaid work, but the notice rules and deadlines are strict and differ by state. Check local rules early, since some deadlines start from the day you finish the job.

Whatever you choose, keep your messages factual. No threats, no calls at odd hours, no telling the neighbors.

Track a collections list, oldest first

You can't collect what you can't see. Keep one list of every open balance, sorted oldest first, with:

• Customer name and phone
• Invoice number and amount
• Date of the job
• Days past due
• Last reminder sent and what's next

Work it from the top every week. The oldest balances are the hardest to collect, so they get attention first. A spreadsheet works when you have a handful of open invoices. Once you have dozens, it falls behind.

If your techs are paid on commission, decide whether they're paid on billed or collected money, and say so in writing. Our free commission calculator helps you run the numbers, and how to pay subcontractor technicians covers the settlement side.

How DispatchMind handles collections

In DispatchMind, invoices come from the job in one tap, using prices from your own price book, and customers can pay by card online.

On the Team plan, automations and reminders keep the follow-up on schedule. Set a rule once: when a job is marked done, tag it "Ready to invoice." After 3 days, if the balance is still open, remind the office. You pick the timing, so you can line the reminders up with the day 1, 7, 14 and 30 schedule above and nobody has to remember who's next.

On Pro, the collections list puts every open balance in one place, oldest first. Jobs that haven't moved in 60 days get flagged, so a forgotten job doesn't turn into lost money. The dialer (DispatchMind Phone) rings 1 to 5 of them at once from your business number without leaving the app, which makes the day 30 calls go fast.

Other tools handle reminders too. For example, Jobber includes automated quote and invoice follow-ups on its Connect plan, as of October 2026. Compare what each plan includes before you pick. For more on choosing, read job management software and Workiz alternatives.

Questions

How do I ask a customer for payment without being rude?

Keep it short, friendly and specific: the invoice number, the amount, the due date and a link to pay. Plenty of late payers simply forgot, and a polite reminder is often all it takes.

How often should I send payment reminders?

A simple schedule works: the invoice on day 1, then reminders on day 7, day 14 and day 30. Add a phone call at day 30 if there's still no answer.

When should I send an unpaid invoice to collections?

Many owners escalate somewhere between 30 and 90 days, once they've sent reminders, called and offered a payment plan with no reply. Collection rules vary by state, so check local rules first.

Can I take a customer to small claims court for an unpaid invoice?

In many cases, yes. Dollar limits, fees and filing steps depend on your state and county, so check your local court's rules. Bring the estimate, work order, photos, invoice and your reminder history.

What's the best way to track unpaid invoices?

Keep one collections list with every open balance, sorted oldest first, and work it from the top every week. Software that builds the list for you and reminds you when to follow up keeps it from going stale.
