The work is done, delivered, and praised — and the money still has not arrived. Every freelancer knows this moment, and in Thailand's kreng jai culture many let it slide until the outstanding pile reaches five or six figures. Here is the truth: systematic follow-up is not being annoying. It is a mark of professionalism, and good clients consistently respect freelancers who clearly have a system. This is how to build one in MANA.
Step 0: Prevent it at the quotation stage
The best debt collection is the kind that never happens. Put the terms in the quotation from day one:
- Payment due within 15 or 30 days of the invoice date
- A 30–50% deposit before work starts, for every new client
- Large projects split into milestone payments — never one lump sum at the end
Clients who agree to these terms up front pay on time far more often, because the expectation was set before the work began.
Step 1: Every invoice gets a due date
In MANA, set a due date on every invoice you issue. No exceptions. The due date is what converts "I feel like this client is slow" into "this invoice is 12 days overdue" — a fact, not a feeling. The moment a date passes, the invoice shows as overdue on its own. Nothing to remember, nothing to check manually.
Step 2: Review all outstanding invoices weekly, in one place
Once a week, open your invoice list and filter to unpaid. You see who owes, how much, and for how long. It takes five minutes — and it is the highest-value five minutes in a freelancer's week, because invoices chased early get paid at a dramatically higher rate than invoices left in silence.
Step 3: Follow up in beats, with the right tone
A three-beat rhythm that works with Thai clients:
Beat one — 2–3 days before due (a service-style reminder):
"Hi! A friendly note that invoice INV-2026-014 for 35,000 baht is due this Friday. You can scan the QR right on the document — let me know if another channel is easier."
Beat two — 3–7 days overdue (polite, more direct):
"Following up on invoice INV-2026-014, now 5 days past due. Could you check the transfer status on your side? If it has been paid, please send the slip and I'll issue the receipt right away."
Beat three — 14+ days overdue (formal, with a deadline):
"Following up once more on the outstanding balance for INV-2026-014. If payment is not received by [date], I will need to pause the remaining work until the balance is settled."
The rule across all three: always cite the document number, amount, and date. Specificity keeps the message about business, never about emotion.
Step 4: Remove excuses with PromptPay and slip verification
The classic stall is "let me find your account number." Kill it with a PromptPay QR on every invoice — the client scans and pays in ten seconds. When the slip arrives, MANA verifies it against the bank automatically: a real transfer, the right amount, not an edited screenshot. Then record the payment against the invoice. If the client pays partially, record the partial amount — the system tracks the remaining balance so your next follow-up quotes the exact figure.
Step 5: Close well — and learn
When full payment lands, issue the receipt immediately with a thank-you. That speed is what makes clients think twice about paying you late next time. And for clients who need heavy chasing every single round, your MANA history gives you evidence to decide calmly: raise their deposit to 70%, switch to payment-before-work, or let them go.
