How Do I Invoice a New Customer Safely?

New customers carry the most risk

You have no payment history with a new customer, so the first job is where you are most exposed. A surprising share of bad debts come from first-time customers who turn out to pay slowly or not at all. That does not mean treating everyone with suspicion — it means putting sensible protections in place on the first job, before trust has been earned through actual payment.

The good news is that a few simple steps remove most of the risk: agree terms in writing, take money up front where it is warranted, confirm exactly who you are billing, and invoice promptly. None of these are difficult, and together they turn a risky first job into a safe one.

Agree terms in writing first

Before any work starts, set out your terms and get the customer's agreement — your price, what is included, when payment is due, and any deposit. A quote the customer accepts by email is enough; you do not need a formal contract for most jobs. What matters is that the terms exist in writing and the customer clearly agreed to them.

This written agreement is your foundation. It removes "I didn't realise" disputes, anchors the payment date, and gives you something concrete to rely on if the invoice goes unpaid. Vague verbal arrangements are where new-customer jobs come unstuck. See whether to credit check before invoicing for an extra layer on larger jobs.

Take money up front where warranted

For a new customer, a deposit or upfront payment is the single most effective protection. It covers your committed costs and, just as importantly, tests whether the customer is genuinely willing and able to pay before you sink real time and materials into their job. A customer who pays a reasonable deposit without fuss is showing you they are serious.

Size the upfront amount to the risk: more for a large first job, less or none for a small low-cost one with a customer who seems solid. See how much deposit to ask for and whether you can require payment up front. A new customer who resists any payment at all on a risky job is telling you something useful.

Confirm who you're billing

Make sure you know exactly who the customer is and who is responsible for paying. For a business, get the correct legal entity name and ABN, not just a trading name — these can differ, and billing the wrong entity makes recovery harder later. Confirm the contact, the billing address and how they want to be invoiced.

This detail matters most if things go wrong. If you ever need to recover an unpaid invoice, you need to know precisely who owes the money. A correctly addressed tax invoice to the right entity is far easier to enforce than one made out to a vague trading name. A good invoice generator helps you capture these details cleanly.

Invoice promptly and follow up

With a new customer, prompt invoicing and prompt follow-up matter even more, because this first cycle teaches the customer how you operate. Invoice the moment the work is done, with clear short terms and an easy way to pay, then send reminders on schedule. Letting the first invoice drift signals that being slow is acceptable.

If a new customer pays late despite reminders, take it seriously — early slow payment is often a warning sign. Keep your written agreement and invoice on hand, and if it remains unpaid well past terms, escalate.
