How it works

1

Start from the invoice date

The clock usually starts the day you issue the invoice. Getting the invoice out the day the job finishes is the single biggest thing you can do to get paid sooner.

2

Apply your terms

“Net 30” means 30 days from the invoice date. “EOM” means the end of the month the invoice was issued — handy if a customer pays all their bills in one monthly run.

3

Track the countdown

Knowing the exact due date — and how many days are left — tells you when a friendly reminder is due and when an invoice has tipped into overdue.

Frequently asked questions

What does “Net 30” mean?

“Net 30” means the full invoice amount is due 30 days after the invoice date. Net 7, 14 and 60 work the same way with different day counts. It’s the most common way trades and their customers agree payment timing.

What are EOM terms?

“EOM” (end of month) means payment is due at the end of the month the invoice was issued, regardless of the exact issue date. “End of next month” pushes it to the end of the following month. EOM suits customers — often larger builders or businesses — who batch-pay all invoices once a month.

What payment terms should tradies use?

Shorter is better for cash flow. Net 7 or Net 14 is increasingly standard for trades, and “due on receipt” is fair for smaller domestic jobs. Net 30 is common with commercial clients and builders but ties up your cash for a month — only offer it if the customer genuinely needs it.

When can I start charging late fees or interest?

From the day after the due date, provided your terms allow it. Use this calculator to pin down the exact due date, then our late payment interest calculator to work out what an overdue invoice is costing.

This calculator is a general guide. Due dates assume payment terms run from the invoice date and don’t adjust for weekends, public holidays or specific contract wording. Always state your payment terms clearly on every invoice.
