If you run a small business and any meaningful share of your revenue is invoiced rather than paid up front, you’ve already met the problem this post is about. The invoice goes out, the work is done, the due date passes, and the customer goes quiet. Twenty percent of your AR is now older than 30 days. Some of it is older than 90.
The framing most owners reach for is “do it in-house or hand it to an agency.” That framing is incomplete. There’s a third option that’s existed for less than a decade and changes the math materially. This post walks through all three and what to actually do this week, depending on where you are.
The default reality for small businesses
A few numbers that match what most small-business owners experience.
Roughly half of B2B invoices are paid late. The average small business has 14% of its receivables more than 30 days overdue at any given time. Owners spend 10 to 15 hours per week on payment chasing, directly or through whoever is doing the bookkeeping. About a quarter of small-business failures attribute cash flow problems as a primary cause, and overdue receivables are a significant input to that.
That’s not a marketing problem. It’s a structural one. The invoice-to-cash gap is the single biggest cash-flow drag on most small service businesses, and there’s no version of “do better next time” that fixes it after the work is done.
Option 1: Keep doing it in-house, by hand
This is what most small businesses default to. The owner, the office manager, or whoever is closest to the invoicing software sends reminders, makes phone calls, and chases overdue accounts.
What works:
- Cheapest option in dollars (no software fee, no agency fee).
- Highest recovery rate in the first 30 days (because the messages come from you, not a third party).
- Customer relationship survives.
What doesn’t:
- Persistence is the variable that matters most, and humans can’t sustain it. The first reminder is professional. The fourth is desperate. By week six the chasing has stopped, and the account is now 90+ days late.
- Owner time is the most expensive resource in a small business. Spending 10 hours a week on collections isn’t free; it’s the most expensive labor cost in the business.
- The communication channel is wrong. By the time an account is aged, the debtor has filtered your emails. SMS reaches accounts that have stopped opening email, but most small-business owners are email-only.
- There’s no real path forward for the debtor. “Please pay your invoice” is an ask, not a path. A path is “settle for 70% this week” or “take three monthly payments.”
In-house works in the first 30 days. Past that, the recovery rate drops fast unless the process changes.
Option 2: Hand the account to a collection agency
The standard escalation. The agency takes the account, sends letters under their name, calls the debtor, and either recovers or doesn’t. They take a contingency fee on what they recover, typically 25% to 50% depending on debt age and size.
What works:
- The agency has skip-tracing tools to find debtors who have moved.
- If the debt is large enough to justify litigation, the agency can refer to a collection attorney.
- The owner’s time is no longer involved.
What doesn’t:
- The customer relationship is over. The moment the debtor gets a letter from a collector, you are functionally fired. Even if they pay, they’re not coming back.
- The math is brutal. On a $4,200 invoice that recovers at 30% with a 35% contingency, you net $441. The agency takes $189. You wrote off $3,570.
- The recovery rate isn’t actually that high once the account is in the 60+ day bucket. Typical agency recovery is 20-30% of placed dollars on small-business accounts.
- It signals badly to your other customers if it gets back to them (“did you hear they sent so-and-so to collections?”).
Agencies are a salvage tool. They make sense for accounts you’ve effectively written off and want to make a last-ditch attempt on. They don’t make sense as a routine response to 60-day-overdue invoices, which is the way most small businesses use them.
Option 3: Software that runs first-party recovery for you
This is the option most small-business owners haven’t priced. Software that runs first-party recovery sequences in your business identity, on the same multi-channel cadence as a collection agency, but without the third-party identity, the contingency fee, or the relationship damage.
ti3 is what we build. The mechanics:
- You upload your aging report (QuickBooks 1-click, Excel, or paste-in).
- ti3 runs a 5-week structured recovery sequence on each overdue account: SMS plus email reminders, weekly, in your business identity.
- The debtor sees the message as coming from you. They get options to pay in full, settle for less, build a payment plan, or dispute.
- Recovered money routes directly to your Stripe or PayPal account. ti3 never takes custody of debtor funds. Self-Serve and Managed are flat monthly fees, not contingency.
- Most accounts settle by week four.
Pricing is software pricing, not collector pricing. Self-Serve is $49/month. Managed (we run the program for you) starts at $499/month. The Managed plan includes a 30-day money-back guarantee: if we recover nothing in your first 30 days, we refund the month and send you a written report on what we found.
Where this option works:
- Accounts in the 30-to-90-day overdue range, where first-party recovery still has the structural advantage but you can’t sustain the persistence yourself.
- Owners who don’t want to spend 10 hours a week on collection work.
- Service businesses where the customer relationship matters and a collector would be the wrong signal.
Where it doesn’t:
- Accounts that have been silent for over a year and the debtor has moved or shut down. Skip tracing matters more than persistence at that point. Agency or attorney is the right tool.
- Disputed accounts. ti3 doesn’t recover debt that’s in active dispute. Resolve the dispute first.
- Single very large accounts ($25,000+) where bespoke human handling lifts recovery materially. We handle these too, but the standard 5-week sequence isn’t always the right tool by itself.
How to think about the math
Run this exercise on your last three overdue invoices.
For each one, write down: the original amount, the days overdue, what you’ve already tried, and what you’d realistically expect to recover under each of the three options.
A typical small-business answer:
| Approach | $4,200 invoice, 60 days late | Net recovery |
|---|---|---|
| Keep emailing it yourself | Probably 50% × maybe-recovers-eventually | $1,000-2,000 (and your time) |
| Hand to a collection agency | 30% recovery × 35% contingency cost = 19.5% net | $819 |
| Run a structured 5-week recovery in your name | ~70% likelihood of recovery, full amount or settled | $2,500-4,200 |
Numbers are rough. The point isn’t the exact figure. The point is that the agency math is worse than most owners assume, and the “keep emailing it” math is worse than that.
What to do this week
Three concrete steps.
- Pull your aging report. Look at every account 30+ days overdue. Pick the three highest-dollar ones and the three oldest ones.
- Decide which option each account belongs in. Past 1 year and silent: probably agency or write-off. 30-90 days: structured recovery. 60-180 days: structured recovery, with the math leaning further toward structured the older the account is.
- For accounts you’d run through structured recovery, send us the aging report. We’ll come back within 48 hours with an estimate of recoverable balance and timeline. No commitment, no sales call.
The math doesn’t get better the longer you wait. A 60-day-late account is materially more recoverable than a 120-day-late account. Whatever you decide, decide soon.
FAQ
How long do I have to collect a small-business debt before it’s too late?
Two clocks run at once. The practical clock is recovery odds: an invoice loses recoverability fast after 90 days, and an account silent for a year is mostly a skip-tracing problem, not a persistence one. The legal clock is your state’s statute of limitations on written contracts, which ranges from roughly 3 to 6 years in most states. You can still ask for payment after the statute expires, but you lose the ability to sue. The practical clock almost always closes first, which is why the advice here is to move on 30-to-90-day accounts now rather than wait.
Can I charge interest or a late fee on the overdue invoice?
Usually yes, if your contract or original invoice stated the rate, and within your state’s legal cap. Late-fee and interest rules vary widely by state. We keep a full breakdown in late payment interest rates by US state. If you never specified a rate up front, your ability to add one retroactively is weak, so the cleaner play is often to use the fee as a negotiating lever (“I’ll waive the accrued late fees if we settle this week”) rather than a hard line.
Is using debt collection software the same as turning my customer over to collections?
No, and the distinction is the whole point. A traditional agency contacts your customer under the agency’s name, which ends the relationship. First-party software sends the same structured cadence under your business identity, so to the customer it reads as your own accounts-receivable follow-up. The customer relationship survives, which matters most for service businesses with repeat clients. For more on the four routes and how to choose, see small business debt collection options in 2026.
What if I’m not sure an account is worth pursuing at all?
Start with the highest-dollar and oldest accounts on your aging report, then estimate recoverable balance before you spend time or money chasing. Send us the aging report and we’ll come back within 48 hours with an estimate of what’s recoverable and a realistic timeline. There’s no commitment and no sales call, so you can use the estimate to triage even if you decide to handle the recovery yourself.
