Knowing when to send accounts to collections isn’t always an easy call. Send an account too soon, and you could damage a customer relationship over a simple billing issue. Wait too long, and your chances of getting paid can drop significantly.
So, where’s the line? There’s a critical window when taking action can make the difference between getting paid and writing off the debt. This guide breaks down the timeline for when to send accounts to collections, key warning signs, choosing a collection agency, and how to know when an overdue account is unlikely to be paid without professional help.
Why Timing Matters More Than Most Businesses Realize
The data on this is more dramatic than most owners expect. According to a survey of Commercial Collection Agencies of America members, the probability of successfully collecting an account drops sharply as it ages:
- At 90 days past due, the likelihood of collection is around 68.9%
- At 6 months past due, it falls to roughly 51.3%
- At 1 year past due, it drops to about 21.4%
That’s not a gradual decline, it’s a cliff. An account you have better-than-even odds of recovering at three months becomes a coin flip by six months and a long shot by a year. Every month you wait isn’t neutral; it’s actively working against you.
When to Send Accounts to Collections: The Timeline
Days 1-30: Internal Follow-Up
This is a normal business, not collections. Most invoices go unpaid for reasons that have nothing to do with a customer’s ability or willingness to pay, an invoice got buried, a billing contact changed, and an approval is stuck internally. At this stage:
- Send a friendly reminder within 7 to 10 days of the due date passing
- Confirm the invoice reached the right person
- Offer an easy way to pay or ask if there’s a dispute, you’re unaware of
Sending an account to collections this early is premature in almost every case, and it can damage a relationship over something that was never actually a payment problem.
Days 30-60: Direct, Documented Communication
If reminders haven’t worked, escalate the tone and start documenting everything in writing.
- Move from casual reminders to a direct phone call or email that clearly states the amount owed and asks for a specific response
- Put any promises or excuses in writing, “customer stated payment would be made by [date]”
- If a customer proposes a payment plan, get it in writing with dates and amounts
This is also the point where you send a formal demand letter if you haven’t already, one that states the balance, the original due date, and what happens if it remains unpaid. This step matters beyond just prompting payment. It creates the documentation a collection agency, or a court, will eventually want to see.
Days 60-90: Evaluate Outside Help
By this point, a non-response or repeatedly broken promise is a real signal, not a fluke. Start evaluating whether this account is a collections candidate:
- Has the customer stopped responding entirely?
- Have they broken a payment plan they agreed to?
- Is the balance large enough that a collection agency’s fee still leaves you meaningfully ahead? (More on this below.)
This is the stage to start researching agencies and getting your documentation together, even if you’re not ready to place the account yet.
Day 90+: Place the Account
Most sources across the industry converge on the same number: 90 days past due is the widely cited threshold for sending an account to collections, some businesses submit right at that mark, others wait until 120 days to give more room for resolution, but very few recommend waiting past that. Beyond 90 to 120 days, you’re trading recovery probability for very little additional benefit.
Do the Math Before Deciding When to Send Accounts to Collections
Not every past-due account is worth sending collections, and the math is worth doing before you decide, not after.
Commercial collection agencies typically charge 10% to 25% in contingency fees, though rates run higher, 20% to 50%, for consumer debt or older, harder-to-collect accounts. A simple example: on a $300 invoice at a 20% contingency rate, successful collection nets $240. Factor in the time spent gathering documentation and coordinating with the agency, and your effective recovery is a bit lower still.
For very small balances, this math can tip against pursuing collections at all. Most agencies also have practical minimums, often somewhere in the $100 to $500 range, below which an account isn’t economically worth their effort or yours. If you have a handful of small unpaid invoices from the same industry or customer type, bundling them can sometimes make placement worthwhile even when a single small invoice wouldn’t be.
When to Send Accounts to Collections Sooner or Reconsider
The 90-day rule of thumb is a default, not a rigid rule. A few situations change when to send accounts to collections, either speeding up the timeline or pausing it altogether:
Move faster than 90 days when:
- The customer has gone completely unresponsive after multiple direct attempts to reach them
- A payment plan was broken and the customer has stopped communicating
- You have reason to believe the customer is winding down the business or preparing to close accounts
Reconsider collections entirely when:
- The customer’s business has failed or filed for bankruptcy. A collection agency can’t recover money that genuinely doesn’t exist, and bankruptcy proceedings follow a separate legal process.
- The balance is too small to clear a collection agency’s minimum or make the fee worthwhile after accounting for your own time.
- The debt itself is disputed, and you don’t have clean documentation, an invoice, signed agreement, or delivery confirmation, to support it. Sort out documentation gaps before placing the account, not after.
What You’ll Need Before You Send an Account
Whenever you do decide when to send accounts to collections, having a complete file ready speeds up the process and improves your odds:
- The original invoice or signed agreement
- A record of all communication attempts, dates, what was said, any promises made
- Copies of any formal demand letters already sent
- Full contact information for the debtor
Collection agencies work faster and more effectively with a complete file than with a bare balance and a name.
One Consequence Worth Knowing
Once an account moves to collections, especially consumer accounts, it can be reported to credit bureaus and may remain on the debtor’s credit report for years. This is often what finally prompts payment once an agency gets involved, but it’s also part of why the decision on when to send accounts to collections shouldn’t be made lightly for a customer relationship you still value. If you want to preserve the relationship, a last direct conversation before placement is usually worth having.
Frequently Asked Questions
Most businesses treat 90 days past due as the standard point to decide when to send accounts to collections. Before that, direct follow-up (days 1-30) and documented communication (days 30-60) give the customer a fair chance to resolve a simple billing issue. Waiting past 120 days rarely helps, since recovery odds drop sharply the longer an account sits unpaid.
There's no fixed minimum, but sending an account to collections before 30 days is almost always premature. Most unpaid invoices at that stage stem from internal delays, not an unwillingness to pay, so early placement risks damaging the relationship over a non-issue.
Yes. It makes sense to move faster than the usual 90-day window if a customer goes completely unresponsive, breaks an agreed payment plan, or appears to be winding down their business. In these cases, waiting for the standard timeline can cost you more than acting early.
Reconsider collections if the customer has filed for bankruptcy, if the balance is too small to clear an agency's minimum fee, or if the debt is disputed and you lack documentation like a signed invoice or delivery confirmation. In these cases, other steps, such as bankruptcy proceedings or resolving documentation gaps, come first.
Collection agencies typically work on contingency, charging 10% to 25% of the recovered amount for commercial debt, and 20% to 50% for consumer debt or older accounts. There's usually no upfront fee, but agencies often have practical minimum balances, commonly $100 to $500, below which pursuing collections isn't cost-effective.
Bottom Line
There’s no single right day to send an account to collections, but there is a clear pattern: give genuine payment issues 30 to 60 days to resolve through direct communication, then treat 90 days as the point where waiting starts costing you more than it saves. Beyond that, recovery odds fall fast enough that hesitation has a real price.
