Should You Send an Unpaid Invoice to Collections (and When)?

Sooner or later every business hits the invoice that just won't get paid. You've sent the reminders, made the calls, and the money is still sitting there months later. At some point the question comes up: should you just hand it to a collection agency and be done with it?

It's a real option — but it's also a one-way door for the customer relationship and an expensive one. Here's how to know whether you're actually at that point, and what to weigh before you pull the trigger.

When does it make sense to send an invoice to collections?

Collections is a last resort, not a follow-up step. It generally makes sense only when most of these are true:

• The invoice is seriously past due — typically 90+ days, well past your normal terms.
• You've made multiple documented attempts — reminders, calls, a firm final notice — and gotten silence or broken promises.
• The relationship is already over — you're not counting on repeat business from this customer.
• The amount justifies the cost and hassle — chasing a small invoice through an agency often isn't worth what you'll lose in fees.

What does sending an invoice to collections actually cost?

More than people expect, in two currencies.

Money. Traditional collection agencies typically keep a large cut of whatever they recover — often 25% to 50% of the invoice. On a contingency basis you don't pay upfront, but you hand over a big slice of money you were already owed. So a "recovered" invoice often comes back as half an invoice.

The relationship. Once an account goes to collections, the customer relationship is effectively finished. The tone changes from "we'd like to sort this out" to "a third party is now pursuing you." For a customer who was genuinely going to pay — just late, disorganized, or going through a rough patch — that's a bridge you can't rebuild.

That's why the timing matters so much: collections can recover some of the money, but it spends the relationship to do it.

The step most businesses skip first

Here's the gap most owners miss: there's a huge middle ground between "I keep awkwardly chasing this myself" and "I send it to an agency that takes half and ends the relationship."

That middle ground is consistent, professional follow-up that doesn't sound like a threat. A lot of overdue invoices aren't refusals — they're invoices that fell through the cracks, and the only reason they're unpaid is that no one followed up firmly and on schedule. The owner is too busy, too uncomfortable, or too close to the customer to keep at it.

When that follow-up happens reliably — in your name, on a steady cadence, with a tone that stays firm but human — a large share of "I'll have to send this to collections" invoices simply get paid. No agency cut, no scorched relationship.

Where Collector fits

That's exactly the gap Collector is built for. It follows up on every aging invoice in your name, on your terms — steady, professional, and human — so the invoice gets chased the way you would if you had the time and the stomach for it. There's $0 upfront, and it only takes 20% on what it actually recovers, versus the much larger cut a traditional agency keeps.

Collections will always be there as the nuclear option. But for most overdue invoices, the right move is to close the follow-up gap first — and reserve the agency for the few accounts that truly earn it.
