Getting paid on time: the invoicing and reminder playbook
Late payment is not a character flaw in clients. It is what happens when invoices are tied to events the client controls, sent irregularly and chased reluctantly. This playbook fixes the three: a schedule tied to dates, an invoice that is easy to pay, and a reminder sequence that runs whether or not you feel like chasing.

In this playbook
- A retainer and stage payment schedule for residential work
- An invoice checklist that removes the excuses
- A reminder sequence from three days before due to thirty days overdue, written out
- Wording for pausing work, and notes for India, the UAE and the US
Two and a half months between doing the work and being paid for it means a studio is, in effect, lending its clients money interest free. For a practice of a few people that gap is the difference between comfortable and anxious, and it is mostly within your control.
Invoice on a date, not on an event
"Payable on completion of schematic design" sounds reasonable until the client takes five weeks to approve the schematic. The work is done, the invoice cannot go out, and the delay is entirely theirs. Tie invoices to dates wherever you can, or to the submission of a stage rather than its approval.
| When | What | Share of fee |
|---|---|---|
| On signing | Retainer, credited against the final invoice | 10 to 15% |
| Monthly during each stage | Work done that month | Pro rata |
| On submission of each stage | Balance of that stage | Remainder of stage |
| Authority submission | Submission stage, invoiced when submitted, not when approved | Per schedule |
The retainer does two things. It confirms the client is serious before you start drawing, and it gives you a buffer so a late stage payment does not immediately become a cash problem.
Make the invoice easy to pay
- Send it the day it is due to go out, every time, so the rhythm is predictable
- Name the stage and the deliverables it covers, so it is not queried
- State the due date as a date, not as "30 days"
- Include bank details and a payment link on the invoice itself
- Address it to the person who pays, and copy the person who approves
- Keep it to one page
Most late payments are not refusals. They are invoices that were queried, forwarded, or waiting for a detail. Every item on that list removes one of those reasons.
The reminder sequence
Chasing feels awkward, so studios put it off, and every day of delay teaches the client that your invoices can wait. A fixed sequence removes the decision. It runs on the calendar, it is polite at every step, and it escalates slowly.
| When | Tone | Channel |
|---|---|---|
| 3 days before due | Friendly heads up | |
| Due date | Simple reminder | |
| 3 days overdue | Direct, still warm | Email and WhatsApp |
| 10 days overdue | A call, then a written note | Phone, then email |
| 21 days overdue | Formal notice | |
| 30 days overdue | Work paused, per the agreement |
Hi [Name], a quick heads up that invoice [number] for [stage] is due on [date]. Payment details and a link are on the invoice. Thank you.
Hi [Name], invoice [number] for [stage] was due on [date] and I cannot see it has come through yet. Could you let me know when to expect it? If anything on it needs clarifying, just say.
Dear [Name], invoice [number] for [amount], due on [date], remains unpaid. Under clause [x] of our agreement, work on the project will pause if payment has not been received by [date, nine days from now]. We would much rather keep going, so please let me know if there is anything we can resolve.
Stop work, politely and on paper
The right to pause work for non payment only helps you if it is in the agreement and you are willing to use it. Most clients pay the day they receive a notice of suspension, because the project matters more to them than the invoice did. Use it rarely, give clear notice, and say exactly what restarts the work.
Dear [Name], as we have not received payment of invoice [number], we have paused work on the project today in line with clause [x]. We will restart as soon as payment arrives, and the programme will move by the length of the pause. We would like to get going again, so do call if it would help to talk it through.
Regional notes
- India: if your practice is registered as a micro or small enterprise through Udyam, the MSMED Act 2006 caps agreed payment terms from buyers at 45 days and provides for compound interest on late payment. Check with your advisor whether it applies to your agreements, and if it does, say so on your invoices.
- UAE: retainers and stage payments before the next stage starts are widely accepted for residential work. Put the retainer in the proposal, not only the contract, so it is agreed up front.
- United States: payment terms and interest on late payment are set by your agreement and by state law, which varies. The AIA agreements provide for interest on overdue amounts; state the rate in your agreement if you use one.
