Why reminders work better before the due date
Most customers who pay late haven't decided not to pay; they've forgotten, or the payment got stuck behind other things. A friendly message a few days before the due date, with the amount and how to pay, gets most balances in without any chasing. The follow-ups are for the rest.
Put the invoice number in every message and ask customers to use it as the PayNow reference. Then the payment shows up in your bank with that reference, and you know exactly which order it's for, instead of relying on a screenshot. See the free PayNow QR generator to make a QR with the amount and reference built in.
Questions
How do I ask a customer to pay a balance politely?
Remind them before it's due, not after: tell them the work is almost ready, the amount, the due date and how to pay. Most late payments are forgotten, not refused.
When should I send a payment reminder?
A few days before the due date, then 1–3 days after, then about a week later. Keep the last one calm and factual, with a clear new date.
Should I put the PayNow details in the message?
Yes. The easier it is to pay, the sooner they pay. Add your UEN or mobile and the invoice number as the reference, so you can match the payment in your bank statement.
Is a firm reminder legally enforceable?
These are message templates, not legal advice. If a customer won't pay, get advice before taking further steps.
