Invoice Follow-Up for Electricians: A Playbook That Actually Gets Paid

# Invoice Follow-Up for Electricians: A Playbook That Actually Gets Paid

Hennessy Electric in Atlanta wrapped a $4,200 commercial panel upgrade on a Tuesday in February. The general contractor was net-60. Sixty days later the invoice was due. Ninety days later it was still open. By April, Mark had sent two emails and left one voicemail, and the GC's office manager kept saying the invoice was "in the next check run."

That story is the rule, not the exception. Roughly 57% of small-business invoices are paid late and a third sit unpaid past 90 days (DepositFix, 2026). For electricians the math is worse than it looks. A single $4,200 commercial invoice tied up for 90 days is roughly the parts cost on your next two service calls, your insurance premium, and a week of payroll all sitting on someone else's desk.

This is the follow-up playbook that gets those invoices paid. It is written for residential and commercial electricians invoicing through QuickBooks, Xero, or Jobber, and it is built around what actually works on the phone when a customer is sitting on your money.

## Why Electricians Carry the Worst AR of Any Trade

Two structural facts make electrical contractors uniquely exposed.

First, the commercial side runs on net-30 or net-60 terms. If you sub for a general contractor on a large build, you are not getting paid the week the work is done. You are getting paid when the GC gets paid by the owner, which is itself net-30. Three months of float on a $12,000 rough-in is normal. The bigger the project, the longer the wait.

Second, the residential side runs on surprise. Customers see the breaker panel, the fixtures, and the receptacles. They do not see the diagnostic time, the truck inventory, the permit fee, or the licensed-electrician hourly rate. When the bill arrives it is bigger than they were braced for, and that surprise turns into delay. "I'll pay when I get my next paycheck" is the single most common excuse on a residential invoice between $500 and $3,500.

Layer those two patterns on top of each other and you get a working electrician with three open commercial invoices over 60 days and four residential invoices that are 15 to 30 days past due, all at the same time. Following up on that book of receivables is its own part-time job. Most owners do it on Sunday evenings, badly.

## The Three Customers Who Hold Up Your Invoices

Before any cadence, you need to know which type of customer you are dealing with. Each one needs a different opening line on the call.

**The slow-pay commercial GC.** The invoice is approved. It is sitting in a stack. The bookkeeper runs checks every other Friday. Your call needs to reach the AP clerk by name and ask for the specific check run date. Yelling at this person makes you the last invoice in the next stack.

**The surprised homeowner.** The invoice is bigger than they planned for. They are not refusing. They are stalling. Your call needs to acknowledge the size of the bill, offer a payment plan, and book a specific date. "I can split this into three payments. Can you do the first $620 by Friday?" works far better than "the invoice is past due."

**The disputed-job customer.** They think something was wrong with the work, the price, or both. Your call needs to surface the dispute, separate it from the rest of the bill, and document everything in writing. You can collect on the parts that are not disputed and resolve the rest separately.

If you call all three with the same script you fail two of them. The first thing every follow-up call needs is a thirty-second internal sort of which one you are about to talk to.

## A Follow-Up Cadence That Actually Recovers Money

The recovery curve for invoices is steep. A customer is roughly twice as likely to pay an invoice that hits 7 days past due if they are contacted on day 7 than if they are contacted on day 14. By day 60, the probability of payment without a phone call has dropped sharply. The cadence below treats every invoice as a deteriorating asset that loses value with time.

1. **Day 0 (invoice sent).** Send the invoice within 24 hours of completing the work, while the customer can still see the new outlets and the cleaned-up service entrance. Sending a week later costs you 5 to 10 days of collection time and gives the customer time to forget the value of the work.

2. **Day 3 (gentle reminder).** A short email or text that says the invoice has been received and is due on date X. This is not a follow-up. It is a confirmation. It tells the customer the invoice is real and visible, and it gives them a chance to flag an issue while it is still small.

3. **Day 7 past due (first call).** A 90-second phone call. Identify yourself, mention the invoice number, ask if there is anything holding it up, and book a specific payment date if the answer is "I'll get to it." "Marcus, this is Mark from Hennessy Electric calling about invoice 4471 for $1,847. Looking for a payment date. Can you do this Friday?"

4. **Day 14 past due (escalation email).** A written notice that the invoice is now 14 days past due, restating the amount, the date due, and the payment methods accepted. Reference the call. Attach the original invoice. Do not threaten.

5. **Day 21 past due (second call, decision-maker).** If the first call was with the bookkeeper or office manager and nothing happened, this one is with the owner or the project manager. Same 90-second structure. Different person.

6. **Day 30 past due (final notice letter or text).** A documented final notice that lays out the next step. For electrical work the next step is usually a mechanics lien filing for commercial jobs or a small-claims filing for residential jobs under your state's limit. Reference the specific filing deadline in writing and follow through if the date passes.

7. **Day 45 past due (file the lien or hand off).** Most electricians have lien rights because electrical work is permanently incorporated into real property. Each state has its own deadline, often 60 to 120 days from substantial completion. If you have not filed by day 45 you are running out of runway.

Run the cadence. Calendar it from the invoice date the day you send it. If you wait until "I have time on Sunday" the cadence collapses and the receivable becomes a write-off.

## What to Say on the Call (Three Scripts)

The scripts below are 60 to 90 seconds each. They are written for the day-7 first call.

**Script 1: The commercial GC.** "Hi Linda, this is Mark from Hennessy Electric. Calling about invoice 4471 for $4,200 from October 12. I see it is now 7 days past due. Wanted to check whether it has been approved for the next check run, and if so what date you expect the check to go out. If there is anything you need from me to move it along, I have my files in front of me right now."

That call is not pushy. It does three things: it names the invoice, it asks for a specific check date, and it offers help. AP clerks pay the squeaky-wheel invoices first because those are the ones the office manager keeps asking about.

**Script 2: The surprised homeowner.** "Hi Sam, it's Mark from Hennessy Electric. Calling about the panel work we finished on October 12. The invoice was $1,847 and I see it is past due. Wanted to ask if everything is working well, and if there is anything about the bill you wanted to walk through. I can also set you up on a three-month payment plan if that would help. The first payment would be $620 by Friday."

The "is everything working" opener disarms the call. It gives the customer a chance to say "actually one of the outlets keeps tripping" before they ghost you. The payment-plan offer makes "I cannot pay $1,847 this week" into "I can pay $620 this week," which is a sale you would otherwise lose.

**Script 3: The disputed-job customer.** "Hi Marcus, it's Mark from Hennessy Electric. Calling about invoice 4471. I noticed it is past due and wanted to ask if there was anything about the work or the bill that did not look right. If there is a piece you want to dispute, let's get that on paper and figure out what you can pay today on the parts that are not in dispute."

That call separates the dispute from the rest of the invoice. You almost always collect 60% to 80% of a disputed invoice the same day if you split it into the agreed portion and the disputed portion. The disputed piece becomes a smaller, less emotional conversation.

## Three Mistakes That Push the Invoice Further Out

**Mistake 1: Waiting "until next month" to call.** A common reasoning goes: I do not want to be pushy, I will give them another two weeks. Two weeks later the invoice is 30 days past due instead of 14, the customer has gotten used to not paying it, and the conversation is now uncomfortable for both sides. The collection probability dropped during those two weeks of silence. Silence is not patience. Silence is a discount.

**Mistake 2: Leading with the threat.** Opening a call with "this is your last chance before we file a lien" before you have asked for a payment date burns the relationship and rarely speeds payment. Customers who feel cornered dig in. Save the lien filing or the small-claims notice for written notice on day 30. The phone calls are for booking payment dates.

**Mistake 3: Calling without an invoice number ready.** "Yeah, hi, calling about the bill we sent last month" loses authority on the first sentence. "Calling about invoice 4471 for $1,847 from October 12" sounds like someone who keeps records and will follow up. The customer hears the difference within two seconds.

## TCPA, Late Fees, and Charging Interest in Plain English

A few legal anchors that matter for the working electrician.

**Calling rules.** Calls to a residential customer about an invoice are governed by federal TCPA rules and your state's mini-TCPA statutes. The practical guardrails: stay inside 8 AM to 9 PM in the customer's local time, do not call after a written request to stop, and document every call. For a B2B GC, TCPA generally does not apply to the same degree, but state laws vary. When in doubt, work inside the 8 AM to 9 PM window for everyone.

**Late fees.** Most states allow late fees on invoices if the original written agreement included them. The common figure is 1.5% per month, which is 18% annualized. If your invoice template does not state a late fee you cannot add one after the fact. Fix the template now. Two months from now the new template will be paying for itself.

**Interest on overdue invoices.** Several states cap interest at a statutory rate even when the parties agreed to a higher one. Florida caps non-judgment commercial interest at the statutory rate in effect for the year. Texas allows up to 18% annually on a written agreement. California's statutory rate is 10% absent a different rate in writing. Check your state. Put the rate in the invoice terms.

**Mechanics lien rights.** Every state grants licensed electricians a lien on real property for unpaid work that became part of the building. Filing deadlines vary from 60 days to 120 days from substantial completion. Calendar the deadline from the day you complete the work, not from the day the invoice goes past due.

## How Syntharra Handles This for Electrical Contractors

The follow-up cadence above works. It also takes between 4 and 8 hours per week of phone time and bookkeeping for a one-truck operation, and double that for a three-truck shop. Most owners get five days into the cadence before the next residential service call eats the time, and the receivables stack starts to grow again.

Syntharra connects to QuickBooks and runs the cadence for you. When an invoice goes 3 days past due, Ara, our AI voice agent, calls the customer, identifies the invoice by number and amount, and books a specific payment date. Inside-window calling only. Identity disclosed on every call. State-by-state interest and late-fee rules respected.

There is no monthly charge. Syntharra is paid 10% of the invoice when the invoice is recovered. A $1,847 invoice paid by the customer pays Syntharra $184.70. A $4,200 commercial invoice paid pays Syntharra $420. If we do not recover, we are not paid.

Connect QuickBooks in under five minutes and Syntharra starts running the cadence on the next invoice that goes past due. Start recovering invoices →
