Your payment terms directly affect how long you wait to get paid. Net 15 and Net 30 are the two most common choices — but picking the right one for your clients and business can meaningfully improve your cash flow.

What Does Net 30 Mean?

Net 30 means the full invoice amount is due within 30 calendar days of the invoice date.

📅 30 days from invoice date to payment deadline
✅ Industry standard for established B2B relationships
✅ Gives corporate clients time to process through their AP system
⚠️ Means you could wait 45–75 days before payment if the client is late

Example: Invoice issued 1 May with Net 30 terms. Due date: 31 May. If the client pays on the due date, you receive payment in 30 days. If they pay 15 days late (the average), you wait 45 days.

What Does Net 15 Mean?

Net 15 means the full invoice amount is due within 15 calendar days of the invoice date.

📅 15 days from invoice date to payment deadline
✅ Better cash flow — you get paid twice as fast (in theory)
✅ Reduces the window for late payment
⚠️ Corporate clients may push back (most AP processes take 14–21 days)
⚠️ More frequent follow-ups needed if clients ignore the shorter timeline

Net 15 vs Net 30: Side by Side

Factor	Net 15	Net 30
Cash flow speed	✅ Faster — paid in 15 days (ideal)	Slower — 30 days minimum
Client friction	Slightly higher for corporate clients	✅ Lower — expected by most businesses
Industry standard	✅ Common for freelancers	✅ Standard for SMB/corporate
Late payment window	✅ Shorter — less time to run late	Longer — more opportunity to delay
AP processing	⚠️ May be too short for large AP depts	✅ Fits most AP timelines
Risk for new clients	✅ Better — less exposure	Higher exposure with unknown clients
Relationship signal	Business-like, efficient	✅ Flexible, relationship-oriented

When to Use Net 30

→Corporate clients with formal AP departments (Net 30 is their minimum processing time)

→Long-term relationships with reliable payment history

→Large invoices where the client needs management approval before paying

→Industries where Net 30 is the universal standard (marketing agencies, consultancies, etc.)

→Clients who explicitly request 30-day terms

When to Use Net 15 (or Shorter)

→New clients — start short and extend terms as trust is established

→Small invoices — a £200 invoice on Net 30 isn't worth 30 days of waiting

→Clients with a proven fast-payment history — reward good payers with flexibility

→Project completion invoices — the work is done, payment should follow quickly

→After a previous late payment — renegotiate to shorter terms going forward

💡 Pro tip:Start all new client relationships on Net 15. If they pay on time for 3–6 invoices, offer to switch to Net 30 as a relationship gesture. You extend trust where it's earned, not by default.

How to Enforce Either Term

Stating payment terms on your invoice is not enough — you need a system to actually collect on time.

State terms prominently on the invoice

Don't bury 'Net 15' in small print. Put the due date clearly: 'Due: 15 May 2026'.

Include a direct payment link

Remove every barrier between 'I got the invoice' and 'I paid it'.

Send a pre-due reminder

7 days before due date, regardless of terms. Clients get busy.

Automate follow-ups

Chaser sends reminders automatically — on day 1 overdue, day 7, day 14, day 30.

Enforce late payment fees

Have them in your contract. Mention them in late reminders. They incentivise timely payment.
