Short answer: most pest control A/R isn't slow, it's rotting. The commonly cited collectibility curve from the Commercial Collection Agencies of America puts a past-due invoice at roughly 94 cents on the dollar at 30 days, about 74 cents at 90 days, 57 cents at six months, and 27 cents at a year. Nothing about the customer changed in that time. Only the number of days nobody called.
Here's the part owners don't want to hear. Almost nobody is refusing to pay you. They got an invoice, filed it, and never heard about it again. Your aging report is not a list of bad customers. It's a list of follow-ups you decided to skip.
What an unpaid invoice actually costs you
Owners think of a write-off as losing the invoice amount. It's worse than that, because you already spent most of it.
A healthy pest control operation runs a 50–55% gross margin, with the industry average closer to 58% (NPMA industry data and PCO Bookkeepers guidance). So on a $9,000 commercial account you end up writing off, roughly $4,000 to $4,500 already walked out the door as tech wages, payroll taxes, product, and fuel. That money is gone regardless. The other $4,500 was your gross profit, and to replace it at the same margin you have to go sell and deliver another $9,000 of work.
Put a real number on your own book. If you're doing $900,000 a year and you write off 1.5% of revenue annually, that's $13,500 of billed work, about $6,750 of gross profit, and roughly $13,500 in new sales you have to produce just to get back to even. That's a technician's worth of route revenue spent chasing your own tail.
Pest A/R comes in two piles, and most owners only watch one
Pile one is the invoices. Commercial accounts, property managers, apartment complexes, restaurants, the one-time termite treatment or exclusion job. These go out on terms, land in an accounts payable queue somewhere, and come back in 30, 45, or 75 days depending on how organized that office is and whether anyone from your side ever follows up. This is the pile that shows up on an aging report.
Pile two is the failed cards, and it barely shows up anywhere. A residential quarterly customer's card expires in March. The charge declines. Your field software flags it, someone means to call, and the route keeps running. Two quarters later that account has had two services performed and zero dollars collected, and it never appeared on an aging report because the system was still treating it as autopay in good standing.
Pile two is usually smaller in dollars and far more embarrassing, because it's entirely self-inflicted. It's also the pile that quietly hides cancellations: a customer whose card has been declining since spring has often already decided to leave and just hasn't told you. You're still routing a truck to them.
The recurring-service trap: you keep sending the truck
In a one-and-done trade, an unpaid invoice stops at one job. Pest control doesn't work that way, and this is the specific reason A/R hurts more in this business than owners expect.
A commercial account on monthly service that's 90 days past due hasn't cost you one visit. It's cost you three, plus the windshield time between stops, and it will cost you a fourth next month unless somebody makes a decision. Every additional service adds real cost to an account whose odds of paying are dropping every week. You are, at that point, running an unsecured line of credit for a customer who is not answering the phone.
The fix is a service-hold rule you actually enforce, written into the agreement at signup: service pauses at a stated number of days past due, and it resumes when the balance clears. Owners hate this because it feels like firing a customer. Compare it against the alternative, which is delivering the same service for free until you write it off, and it stops feeling harsh.
Age is the whole game
The collectibility curve above is the single most useful thing to internalize about receivables. A call at day 32 is a friendly reminder and it usually works. The same call at day 95 is a negotiation, and by month twelve you're paying an agency a third of whatever they can recover.
Which means the value of a collections process is almost entirely in its speed, not its intensity. Owners tend to invest in the wrong end: nothing happens for two months, then a stern letter and a lot of anger. Reverse it. Be boring and early instead of firm and late.
Sort your aging into four buckets and treat them as four different jobs:
- 1–30 days. Not a problem yet. An automated reminder with the invoice attached. No human time.
- 31–60 days. A phone call, not an email. The goal is not payment on the spot, it's confirming the invoice was received and finding out who actually cuts the check. Half of commercial slow-pay is an invoice sitting in the wrong inbox.
- 61–90 days. Owner or manager call, plus a specific date commitment written down. This is where the service-hold conversation starts.
- 90+ days. Decide. Payment plan, hold service, send to collections, or write it off. What you don't get to do is nothing, which is what usually happens.
A collections routine that fits in 20 minutes a week
This does not need to be a department. It needs to be on a calendar and belong to a named person.
Every Monday, pull the aging list. Work top down by dollars, not by age, so the five accounts that represent 60% of the balance get called first. Log every call with a date and what was promised. If a customer commits to a date, put that date on the calendar and call the day after if it passes.
One organizational note that matters more than any script: the person who invoices is often the person with the customer relationship, which makes them the worst person to ask for money. They'll send another email instead of calling. Either give collections to someone with no relationship to protect, or make the owner take the 61-day-plus calls. The reason your A/R is old usually isn't laziness. It's that nobody wants to be the one to bring it up.
The real fix is upstream of collections
Every hour spent chasing money is an hour you'd rather not spend. Most of it is avoidable at signup.
Card on file, no exceptions, on every recurring residential agreement. This is the biggest single lever in the business and it costs you nothing but the discipline to require it. Then set up a card-updater service with your processor so expirations don't silently become collections problems.
Deposits on the big one-time work. Termite jobs, exclusion, crawl space work, anything with real material cost. Half up front, balance on completion. You are not a bank and the material invoice hits you long before the customer's check does.
Write the terms down and make them shorter. Net 30 is a default nobody negotiated. Plenty of commercial accounts will sign net 15 if you ask at the start. None will agree to it after ninety days of you not asking about net 30.
Invoice the day of service, not at month end. A month-end batch means the average invoice is already two weeks old before it leaves your office, and it lands in the same crush of paperwork as everyone else's. Same-day billing moves your collection date forward two weeks for free.
Write it off, or it will lie to you
The last piece is the one that feels like giving up. Receivables over a year old are decorations on your balance sheet. If you bill on an accrual basis, they're also propping up revenue you're never going to see, which makes every margin number and every growth comparison a little bit false.
Keeping a dead $7,000 invoice on the books doesn't preserve any real chance of collecting it. It just makes the business look healthier than it is on the exact report you use to decide whether you can afford another truck. Clean it out annually, take the hit, and make decisions on numbers that are true.
How to actually see it
All of this depends on being able to produce an aging list in seconds instead of an hour. Most owners can't, which is precisely why the Monday call block never happens.
That's part of what we built Forecast for. Connect QuickBooks read-only in about five minutes and you get invoice-level A/R: who owes you, how much, how many days late, sorted so you know which five calls to make first. Connect only a bank account and you'll get cash flow, where the money is actually going, and a solid margin estimate, though invoice-level A/R and exact margin need QuickBooks to be precise. Read-only either way. Ando never moves your money, never sends anything to your customers, and never edits your books.
Nobody collects everything. But the difference between a shop that collects 98% and one that collects 94% is not tougher negotiating. It's a list somebody looks at on Monday morning.
