How agencies and freelancers collect retainers on time
Agency invoices die in accounts-payable queues. The fix is knowing who's in the queue and nudging them before the run, not after.
- Bill retainers in advance, on the 1st, due on the 10th. Never bill a month's work at the end of it.
- Get the AP contact's name and email on day one, and send invoices there, cc the client lead.
- Nudge three days before the due date, then day 1, then email, then a call to AP, not the client lead.
- "It's with finance" is a status, not an answer. Ask when the next payment run is.
Why agency invoices run late
Your contact at the client loves your work and has nothing to do with paying for it. The invoice goes to a shared AP inbox, waits for approval, waits for the next payment run, and arrives 45 days later. Nobody did anything wrong, and you've financed their month.
Most agency collection problems are routing problems, and routing problems are solved before the first invoice goes out.
Set-up that gets you paid
- Bill in advance. Retainers on the 1st, due on the 10th. Project work: 50 percent up front, the rest on milestones.
- Know the payer. On the kickoff call: "Who in your team processes invoices, and what's the email?" Send every invoice there, with your contact in cc.
- Learn the run. Most companies pay on a fixed day: the 15th, the last Friday. Ask. Then time your due date and your reminders to land before it.
- PO numbers. If they use them, no PO means no payment, however good the work. Get it before the first invoice.
- Card option. Some clients will pay by card to skip the AP queue. Offer it.
The reminder schedule for net 30
- Day 27: heads-up to AP, cc client lead: "Invoice #4410 for $6,000 is due Friday."
- Day 31: nudge email to AP.
- Day 34: email with the invoice re-attached, asking for the payment-run date.
- Day 38: a polite call to AP (not the client lead).
- Day 45: a note to the client lead: "Could you give AP a nudge on #4410? Happy to pause the next sprint until it's cleared if that helps."
Handling the standard replies
- "It's with finance." "Great, when's the next payment run? I'll look out for it then." Then diarise that date.
- "We need a PO." Get it, re-issue the invoice with it, same day.
- "Can you resend?" Always yes, instantly, with a card link.
- "We pay net 60." Decide if the volume is worth financing. If yes, bill earlier. If not, say so politely and hold to your terms.
Pausing work
For retainers, the lever is the next month's work. "I'll pause the next sprint until October is cleared" is fair, and it's the one message that moves an AP queue. Say it once, kindly, to the client lead, around day 45.
Automating the agency ladder
Invoice AI runs this schedule for you: the day-27 heads-up, the nudges, the invoice email, and a polite call to the AP contact, each in your agency's name, with replies read and dates noted. You see one morning message: which clients paid, which promised a run date, which need a word from you.
Questions people ask
How do agencies get retainers paid on time?
Bill in advance (1st, due the 10th), send to the AP contact with the client lead in cc, nudge three days before the due date, and time reminders to the client's payment run.
What do I say when a client says the invoice is with finance?
Ask when the next payment run is and whether the invoice is in it. Note the date and follow up the day after if it doesn't arrive.
Should I pause work for a client who hasn't paid?
For retainers, yes, around day 45, said once and politely to the client lead. It's fair and it's the message that moves AP queues.
Can I charge a late fee to agency clients?
If it's in the contract, yes; 1 to 1.5% a month is standard. Many agencies prefer to pause work instead of charging fees.
