When a customer stops responding to your invoices, you’re not actually stuck. You’re at a decision point. The path from that point determines whether you recover the money, keep the relationship, or write the account off.
Most owners drift between the three options for weeks, re-sending the same email and hoping the account magically pays. That doesn’t work. What works is staging the escalation so you move through each phase deliberately, with a clear decision at the end of each one.
Stage 1: Confirm receipt (days 1-7)
Your first message assumes the invoice never landed. That’s not naive. Legitimate failures happen. Email gets blocked. Slack messages disappear. The PO got buried.
Your job: Send one friendly check-in. If they respond at all, you’ve got the path forward. If they don’t, you move to stage 2.
The message is simple. “Hi [name], invoice #4401 for $4,200 was due [date]. If it’s already on its way, ignore this. If not, here’s the link. Let me know if you need anything on my end.” That’s it.
The Stage 1 rule
If they respond within 7 days, you're in a problem-solving conversation, not a collection. Respond quickly and move from there. If they don't respond at all, assume no receipt and move to stage 2.
Stage 2: Surface the problem (days 8-21)
By day 8, your second message assumes one of three things: the invoice landed and they ignored it, or there’s a real blocker you don’t know about, or they’re testing how hard you’ll push.
Your message now is different. It’s more specific. You name a date. You ask for one of three answers.
“Invoice #4401 ($4,200) is now [days] past due and I haven’t heard back. I’d like to close this out. Can you reply by [specific date] with one of: a date you’ll pay by, a specific issue blocking payment, or confirmation you’ve already paid?”
Most ignoring customers will respond at this stage because you’ve moved from “remind me” to “reply with specifics.”
If they reply with a legitimate issue (the work wasn’t complete, the service didn’t deliver, the PO was never approved), you’ve got new information. Fix it if you can, or document the dispute formally if you can’t.
If they still don’t respond by day 21, move to stage 3.
Stage 3: Pattern interrupt (days 21-30)
By day 21, email reminders aren’t working. You need to interrupt the pattern. The subject line changes. The tone changes. The ask changes.
“Are we still on good terms?” works. So does “Invoice #4401: checking in.” The point is to get the email opened by someone who’s been ignoring your previous ones.
The body is direct. “I’m reaching out differently because the reminders haven’t gotten a response. Invoice #4401 ($4,200) is now three weeks past due. Either there’s something specific I can fix, or there’s something going on at your end, or this is heading toward a more formal recovery process. I’d much rather talk through option 1 or 2.”
If they’re still silent by day 30, they’ve made a decision not to pay voluntarily. You move to stage 4.
Stage 4: Offer a path (days 30-45)
By day 30, your leverage is a discount. Voluntary payment stops working. A discount is the cheapest recovery lever you have. A 25% discount on $4,200 nets you $3,150 today instead of zero in six months or $0 if the account never recovers.
Your message offers a one-time settlement. “Invoice #4401 ($4,200) is now 30 days past due. Before this moves to formal recovery, I want to offer a one-time settlement: pay $3,150 (25% off) by [Friday] and we’ll call it paid in full.”
If they don’t take the settlement by day 45, offer a payment plan. “If a single payment isn’t workable, I can split this into three monthly payments of $1,400.”
Hard rule at day 45
Stop offering unstructured flexibility. Settlement or payment plan. Anything else is just more emails, and you've already sent enough of those.
Stage 5: Final decision (day 60+)
If you reach day 60 with no payment, no settlement, and no agreed plan, you’ve hit the endpoint of what email can do.
Your last message is final. “Invoice #4401 ($4,200) is now 60 days past due. This is the last message I’ll send before moving the account to structured recovery. To avoid that, I need one of: payment in full by [date], a signed payment plan, or a written dispute with specifics. If I don’t hear back, the account moves to recovery and money routes directly to you.”
Then you make the call. Three honest paths from here:
Write it off. Some accounts genuinely won’t recover. If the amount is small (under $500) and the relationship is gone, writing it off stops the bleeding and frees you to chase accounts with better recovery odds.
Hand it to a collection agency. Recovery rate on accounts 60+ days past due is typically 30%. The agency takes 25-50% of the recovery. You net 15-22% of the original invoice. The customer relationship ends.
Run a structured recovery sequence. ti3 does this. Five weeks of emails, SMS, and a Final Demand Notice in your name. Settlement and plan paths the debtor can self-serve. Recovered money routes directly to your account. The customer relationship stays intact if it can be saved.
Frequently asked
What if they respond late but promise to pay soon?
Get it in writing. A promise-to-pay email that names a date is better than no commitment, but it’s not a payment. If that date passes and you hear nothing, move straight to stage 4 (settlement offer). You’ve already moved through stages 1-3.
Should I call instead of email?
After day 14, yes, if you have the number and the customer has authorized contact. One phone call can save weeks of email back-and-forth. But text only if explicitly authorized and only after day 14. Email stays your first channel because it creates documentation.
What if they’re actually ghosting because they’re broke?
A broke customer who can’t pay $4,200 can often pay $1,400 over three months (stage 4). Most customers at stage 3+ are cash-flow constrained, not refusing. The structure is what unlocks payment.
How long should I wait at each stage?
Seven days between touches in stages 1-3. Five business days in stages 4-5. Less than five days reads as harassment. More than 10 days lets the account drift back into “I’ll deal with it later.”
What comes next
If you’re in stage 1 or 2 with an account, move through the sequence this week. If you have multiple accounts in stage 3+, the email phase is over. You need a structured recovery process to manage the volume and the follow-up.
ti3 handles stages 4 and 5 for you across multiple accounts. The 30-day guarantee covers the case where recovery doesn’t happen.
