Your invoice says "Payment due within 30 days." Your client pays in 52.

This is the gap between stated payment terms and actual payment behaviour. And for Singapore SMEs, it's one of the most consistent sources of cashflow stress.

The number on your invoice matters. But it matters less than most people think. What actually determines when you get paid is a combination of your terms, your reminder behaviour, and how easy you've made it to pay you.

What's Standard in Singapore

There's no universal standard payment term in Singapore. What you'll encounter varies significantly by industry and client type.

Professional services (consulting, design, legal, accounting): Net 30 is common. Some practitioners use Net 14 or even Net 7 for project-based work.

Construction and contractors: 30-60 days is typical, with progress payments tied to project milestones. Payment delays are endemic to the industry.

Government projects: 30 days from invoice date is the standard, but processing through government finance systems often means actual payment arrives at 45-60 days.

Large corporate clients: Many have fixed payment cycles — typically monthly. Your invoice arrives on the 16th, their payment run is on the 20th, so you wait until next month's run. Effective terms become 45-60 days regardless of what your invoice says.

Retail and F&B suppliers: Consignment terms or 30-day terms are common. Cash on delivery for new suppliers.

The Legal Framework

Singapore's late payment law is relatively weak compared to some jurisdictions. There is no universal statutory right to late payment interest for B2B transactions in Singapore — unlike the UK's Late Payment of Commercial Debts Act, which automatically applies a statutory interest rate.

What you have in Singapore:

Contract-based interest. If your invoice or contract specifies a late payment interest rate, you can enforce it. Without a contractual clause, you have no automatic right to interest.

Small Claims Tribunal. For disputes under SGD 20,000, the SCT is a relatively accessible forum. Filing fee is SGD 10. You don't need a lawyer. Judgments can be enforced.

Magistrate's Court. For amounts between SGD 20,000 and SGD 60,000.

High Court. For amounts above SGD 60,000.

The practical reality is that pursuing late payment legally is cost-effective only when the amount is significant enough to justify the time and stress. For amounts under SGD 5,000, most Singapore SMEs don't pursue legal action — which is exactly what late-paying clients rely on.

What Actually Gets You Paid Faster

Research on payment behaviour consistently shows that certain practices reduce collection time more than others.

Invoice immediately. Every day between completing work and sending the invoice extends your collection period by a day. Same-day invoicing is the single highest-impact change most SMEs can make.

Be specific about the due date, not the terms. "Due by 15 June 2025" is clearer than "Net 30." Clients respond to a specific date more than a calculation they have to do.

Make payment easy. The harder it is to pay, the more likely it gets delayed. A PayNow QR code on the invoice means the client can pay in 30 seconds. Bank transfer details mean they have to log in, find the payee, type in numbers, and add a reference. Some will do it immediately. Others will tell themselves they'll do it later.

Send reminders on a fixed schedule. Invoices that follow up automatically get paid faster than invoices that rely on you to remember to chase. Day 1 after due date. Day 7. Day 14. Every time.

Add a late payment clause. Even if you don't enforce it, a clause stating that invoices unpaid after 30 days accrue 1.5% per month changes the psychology. Clients who know there's a cost to delayed payment are more likely to prioritise your invoice over one with no stated consequence.

The Discount for Early Payment Strategy

One effective approach that's underused in Singapore: offering a small discount for early payment.

"2/10 Net 30" means: take a 2% discount if you pay within 10 days, otherwise full amount due in 30 days.

For a client paying a SGD 10,000 invoice, 2% is SGD 200. That's usually worth it to a finance team trying to capture early payment discounts — it's essentially a 2% return on 20 days of cash, which annualises to over 36%. Most companies will take that.

For you, giving up 2% to get paid 20 days earlier is often worthwhile when you factor in the avoided chasing time and the cashflow benefit.

Building a Payment System, Not a Payment Hope

The businesses that consistently get paid on time don't rely on client goodwill. They have a system.

Invoice sent immediately on completion. Due date clearly stated. PayNow QR embedded. Reminder on day 1 after due date. Reminder on day 7. Reminder on day 14 with escalation language. Every step automatic.

When payment comes in, it's matched to the invoice automatically. The reconciliation updates. The client's account shows as settled.

When payment doesn't come in by day 21, it's flagged for manual follow-up — a human decision about whether to call, escalate, or offer a payment plan.

This is the difference between chasing invoices and managing receivables. One is reactive and stressful. The other is a system you set up once and monitor.

ArcPay automates every step from invoice creation to payment confirmation. Terms are enforced by reminders, not by you remembering to send them. PayNow is on every invoice by default.
