Payment Terms That Get You Paid Faster

It's Thursday, you finished the job Monday, and the invoice still says "Net 30." So you wait — funding someone else's cash flow because of a line you copied off an old template.

Here's the fix: your payment terms are a choice, not a rule. Change the terms, add card-on-file, let reminders chase for you, and the money lands days after the work — not a month later.

This post covers why the long default is just a habit, the terms worth using, how to change terms on customers you already have, and the single sentence that moves payment speed the most.

Key takeaways

• Net 30 is a default, inherited from big-company accounts departments — not a law you have to follow.
• Match terms to your model: due on completion, a short window, a deposit-and-balance split, or direct debit.
• Change terms at the next job, stated in writing with a plain reason.
• Automation beats enforcement: clear terms plus auto-reminders and card-on-file get you paid without the awkward phone calls.

Why is "30 days" the default for so many invoices?

Net 30 is a leftover from big-business accounts payable, not a standard you're bound to. Large companies batch their payments into monthly runs, so a month-long window suited their admin. A one-van plumber or a two-chair salon has no reason to inherit that.

You set your terms. The customer either accepts them when they book or they don't book. On a small residential or appointment-based job, nobody expects to pay a month later — they expect to pay when the work's done.

So why do so many invoices still carry that default? Habit. The template came with it, and nobody changed it. That one word is quietly costing you weeks of cash flow on every job.

What payment terms should a service business actually use?

Pick the shortest terms your customer type will accept. For most Australian service businesses, that's one of a few:

1. Due on completion. Payment is expected when the job's finished, before you leave or at checkout. Best for callouts, salon appointments, clinic visits and anything done on-site. This is the default you should aim for — see how tradies get paid on the day, not 30 days later.
2. A short window. A few days for customers who genuinely can't pay on the spot — small commercial accounts, property managers, repeat clients. Short enough to protect cash flow, polite enough to keep the relationship.
3. Deposit plus balance. Half upfront to lock the booking and cover materials, the balance on completion. Essential for bigger jobs where you'd otherwise be funding stock out of pocket. Our guide on when and how to ask for a deposit walks through the exact wording.
4. Direct debit. For anything recurring — gym memberships, retainers, maintenance plans — the payment runs itself on a schedule. No invoice, no chase.

For staged work that runs over weeks, add a progress payment schedule so you're never funding the job yourself. The progress payments guide shows how to break a big job into stages.

Here's what we'd do: make "due on completion" your default, offer a short window only when a customer needs it, and never write Net 30 again unless a commercial contract forces it.

How do I change terms on existing customers?

Change terms at the next job, in writing, with a plain reason — never mid-invoice on work already agreed. Springing new terms on a customer after the fact feels like a bait-and-switch. At the start of the next job, it's just how you work now.

Use a line like this when you quote: "A quick note — payment is now due on completion. I'll send the invoice the moment the job's done so you can pay by card or transfer on the spot."

"But won't that scare off good customers?" Almost never. Reliable payers don't mind paying sooner — it's slow payers who push back, and those are exactly the accounts you want on tighter terms. Put the new terms on your quotes and booking confirmations so every new customer starts on them automatically.

Pro tip: bundle the terms change with something the customer gains — card payment on-site, instant receipts, a text link to pay. It reframes the change as a convenience, not a crackdown.

The one sentence that gets invoices paid faster

Put the payment method in the invoice, not just the terms. The single line that moves the needle is a clear instruction with a live link:

> "Pay now: [tap here to pay by card]."

A due date tells someone when. A pay link tells them how — and removes every excuse between reading the invoice and settling it. No "what's your BSB again," no "I'll do it from the office." They tap, they pay, you're done. That's the idea behind text-to-pay before you leave the driveway.

Pair it with a specific due date ("Due Friday 10 October") rather than a vague "Net 7." Dates read as real deadlines. Ranges read as suggestions.

Terms are only half the job — the other half is the chase

Clear terms plus automatic reminders beat strict terms you enforce by hand. Writing a due date means nothing if nobody follows up the day after. The fastest-paid businesses don't chase harder — they chase automatically.

Picture a sparky who finishes a switchboard upgrade at 4pm. The invoice goes out before he's off the driveway. If it's unpaid a few days later, a reminder text sends itself. A few days after that, another. He never opens a spreadsheet or makes an awkward call — the system does the nagging, politely, on schedule.

When a customer genuinely won't pay, you escalate. Our chase ladder before the debt collector and the rules on late payment fees and interest in Australia cover what's next. But for most slow payers, a due-on-completion term plus a pay link plus a couple of automatic reminders clears the problem before it starts.

How IgniteOS does this for you

IgniteOS sends the invoice the moment the job's marked done, with a tap-to-pay card link built in — and then chases it for you until it's paid. Payments handles cards, deposits and surcharge-free links; get paid ties the invoice to the job so nothing slips, and automations fire the reminder texts without you lifting a finger.

That means deposits taken at booking, balances due on completion, and recurring plans on direct debit — all from one login instead of a drawer full of apps.

The fastest win from this piece: swap Net 30 for "due on completion" with a pay link on your next invoice. See how the whole flow works on get paid faster, or start a 14-day free trial and send your first tap-to-pay invoice today.

Frequently asked questions

Is Net 30 a legal requirement for invoices?

No. Net 30 is a habit inherited from big-company accounts departments that batch monthly payments — it's not a law. You set your own terms. For most service businesses, due on completion or a short window is fair and gets you paid far sooner than a copied-in default.

How do I change payment terms on existing customers?

Change them at the next job, in writing, with a plain reason — never mid-invoice on work already agreed. State the new terms on your quote and booking confirmation, and bundle them with something the customer gains, like on-site card payment or an instant pay link, so it reads as a convenience rather than a crackdown.

What payment terms are best for a small service business?

Due on completion for callouts, salon and clinic visits; a short window for small commercial accounts; a deposit-and-balance split for bigger jobs with materials; and direct debit for anything recurring like memberships or retainers. Match the term to how you actually work, and keep the window as short as the customer will accept.

What makes customers pay an invoice faster?

Put the payment method inside the invoice, not just the terms. A tap-to-pay card link removes every excuse between reading the invoice and settling it. Pair it with a specific due date and automatic reminders. You can set this up on get paid faster so the invoice and chase run themselves.
