Chasing Outstanding Invoices Before Year End: The Singapore SME Collection Plan That Starts in October

If you want outstanding invoices paid before 31 December, the chase starts now, not in December. An invoice on 30-day terms issued in late October is the last one that can be sent, fall due, be chased twice and still be paid inside the year. On 60-day terms you are already at the edge. So the first move is not a reminder email: it is to pull your accounts receivable ageing report this week, sort it by how old each debt is rather than how large it is, and work the oldest buckets first. That one change in ordering is the difference between closing the year with cash and carrying a list of excuses into January.

Why does mid-October matter more than December?

Do the arithmetic backwards from your customer's last payment run, not from your own calendar. Most Singapore companies pay on a weekly or twice-monthly cycle, and the last practical run before the break usually lands around the third week of December. Behind that run sits an approval that needs a named person to sign, and that person may be on leave from mid-December.

So a 30-day invoice needs to be in their system by roughly mid-November to be paid this year. A 60-day invoice needed to be in by about now. And if the invoice gets queried, you lose the whole cycle again: credit note, reissue, fresh 30 days. Every week you wait in October costs you one full chase attempt in December.

What does an AR ageing report actually tell you?

An ageing report is one list of everyone who owes you money, split by how overdue each invoice is: current, 1 to 30 days, 31 to 60, 61 to 90, and over 90. Every accounting package produces it in under a minute. What it tells you is where the risk is, because the chance of collecting falls sharply with age. Debt under 30 days is normal trading. Debt over 90 days is a problem that already failed to get fixed twice.

Three things to check before you trust the numbers:

• Invoices that were never actually sent. More common than owners expect, especially where one person raises the invoice and another emails it.
• Unapplied payments and credit notes. A customer may look 60 days late because a payment was banked but never matched to the invoice.
• Duplicate customer records. The same client under two spellings splits their balance and hides the real exposure.

Fix those first. Some of what looks like bad debt is simply bad bookkeeping, and correcting it costs nothing.

Which invoices should you chase first?

Sort the overdue list into three piles, because each needs a different action.

Pile one: an admin problem, not a payment problem. The invoice never arrived, went to a staff member who has left, quotes the wrong entity name, is missing a purchase order number, or lacks the delivery order or timesheet their finance team needs to process it. These are the fastest money in the business. Most can be fixed the same day with a corrected invoice and a direct email to the right person.

Pile two: stuck in approval. The invoice is accepted but nobody has signed it. What you need here is not another reminder, it is two facts: the name of the person whose approval is outstanding, and the date of the payment run it will go into. Ask for both in writing. A reminder with no name attached gets filed; a question about a specific person and a specific date gets answered.

Pile three: a real cash problem. The customer cannot pay in full. Your choice is a written instalment plan with dates and amounts, or escalation. Take the plan if the relationship is worth keeping, but put it in an email the customer replies to, and make continued supply conditional on them keeping to it.

What does a working chase sequence look like?

Collections work when they are a routine rather than a reaction. A sequence a ten-person company can actually sustain:

1. Day of issue: invoice sent to the finance contact, with the person who ordered the work copied in.
2. Day 7: short note confirming it was received and logged. This is the cheapest step and it removes the most common excuse.
3. Five days before due: polite reminder with the due date and the payment details repeated.
4. Due date plus 3: telephone call, not email. Ask who approves it and which payment run it is in.
5. Due date plus 10: escalate to the person who ordered the work, and copy their manager.
6. Due date plus 30: formal letter, and a decision on whether work or supply continues.

Keep the tone neutral throughout. The goal is a paid invoice and a customer who still buys from you in 2027.

Can you automate this without sounding like a robot?

Yes, and the saving is real: roughly 40 minutes a week for a small team, plus the invoices that would have been forgotten entirely. Switch on the automatic reminder schedule in your accounting software so the day 7 and pre-due-date steps send themselves, and keep the human for the phone call. Put a PayNow Corporate QR code on the invoice so approval and payment can happen on a phone. If you are moving to InvoiceNow, the national e-invoicing network, invoices land directly in the customer's system instead of an inbox, which removes the "we never received it" problem outright. Check the current GST e-invoicing timetable with your accountant, as the obligations are being phased in by registration date.

One rule: automation sends the routine reminders, a named person owns the exceptions. Software that nobody reviews just produces politely ignored emails.

What must be true before 31 December?

1. The ageing report has been reviewed and the balances agree to your ledger.
2. Every invoice over 90 days old has a named owner, a next action, and a date.
3. Write-offs are decided and documented rather than left to drift into next year.
4. GST bad debt relief has been checked with your accountant for debts old enough to qualify, since the conditions include the age of the debt, the recovery steps you took, and writing it off in your accounts.
5. Credit terms for repeat late payers are changed in writing, not just complained about.
6. A deposit or milestone policy is agreed for 2027 work.
7. Somebody is on duty in the last two weeks of December to bank payments, answer finance queries and send the final invoices.

Chasing invoices is unglamorous and it is the highest-return hour in an owner's week in Q4. Cash collected in December is cash you do not borrow in February.

Frequently asked questions

How often should a small company run its AR ageing report?

Weekly in the last quarter of the year, monthly for the rest. Weekly is not about discipline for its own sake: it is short enough that a stuck invoice gets spotted while there is still time to fix it before the next payment run.

At what point should an overdue invoice be written off?

Write it off when you have decided to stop spending money chasing it, not at a fixed number of days. Document the recovery attempts first, because those records support both the accounting treatment and any GST bad debt relief claim. Your accountant should confirm the treatment before the year closes.

Does chasing payment harm the customer relationship?

Clear, early and consistent chasing improves it. The relationship damage comes from silence followed by a sudden demand, or from stopping work without warning. Finance teams are used to reminders and generally prefer a supplier who tells them exactly what is outstanding and what is needed to clear it.
