How to Invoice as a Tradie — What Must Be on Every Tax Invoice

Getting paid is the most important part of running a trade business — and a lot of tradies leave money on the table with invoices that are incomplete, sent late, or so confusing that clients don't pay promptly. Here's what every tradie invoice must include and how to get paid faster.

What Every Tradie Invoice Must Include

Whether or not you're registered for GST, your invoice should contain:

• Your business name and ABN
• Your contact details — phone number or email
• The date of the invoice
• A unique invoice number — keeps your records organised and helps clients reference it when paying
• Client's name and address — or company name for business clients
• A clear description of the work done — be specific. "Labour and materials for bathroom renovation, 15–17 March" is better than "plumbing work"
• The amount charged, broken down into labour, materials and any other components
• Your payment details — BSB, account number, or PayID
• Payment terms — when you expect to be paid (7 days, 14 days, 30 days)

GST Invoice Requirements

If you're registered for GST, your invoice becomes a tax invoice and has additional requirements for invoices over $82.50 (including GST):

• The words "Tax Invoice" must appear prominently
• Your ABN
• The GST amount charged — either as a separate line or a statement that "the total includes $X of GST"
• For invoices over $1,000 including GST: the buyer's name and address is also required

Your clients need a proper tax invoice from you to claim the GST back on their own BAS. If your invoice isn't correct, they'll chase you to fix it — which delays payment.

When to Send Your Invoice

Invoice the moment the job is done. Not next week. Not when you get around to it. The same day, ideally before you've even packed up your tools. Every day between completing a job and sending the invoice is a day added to when you'll get paid.

For larger jobs, consider milestone invoicing — invoice for a percentage at certain stages (e.g. 30% on start, 40% at frame stage, 30% on completion). Never complete an entire large job before invoicing — you're essentially lending your client money interest-free.

How to Get Paid Faster

• Send invoices immediately — see above
• Use short payment terms — 7 days is reasonable for most residential work. 30 days is for large commercial jobs only
• Make paying easy — include a PayID, bank transfer details and if possible a "Pay Now" link through your invoicing software
• Send a reminder before the due date — a friendly message the day before payment is due catches people who forgot, without being confrontational
• Take payment on-site — for smaller jobs, bring a card reader and get paid before you leave

Best Invoicing Software for Tradies

Creating invoices in Word or sending photos of handwritten receipts is a nightmare to track and looks unprofessional. Good invoicing software creates professional invoices in seconds, tracks who's paid and who hasn't, and syncs with your accounting.

Rounded is the best value for sole trader tradies — invoicing, expense tracking and BAS prep for $15/month. ServiceM8 is excellent if you want job scheduling, quoting and invoicing all in one tradie-specific app.

Payment Terms — Getting Paid Faster

The payment terms on your invoice directly affect your cash flow. Common options:

• Due on completion — payment expected when the job is done. Best for small residential jobs.
• 7 days — standard for most tradie work. Add a late payment clause.
• 14 days — common for commercial clients who have accounts payable processes.
• Progress invoicing — for large jobs, invoice at milestones (25%, 50%, 75%, completion). Never do large jobs without progress payments.

Invoice Automation — Save 2+ Hours Per Week

Manual invoicing in Word or a spreadsheet wastes time and creates errors. Dedicated invoicing tools send automatically, track who has not paid, and send reminders — all without you chasing clients manually.

## Getting Paid Faster: Invoice Timing and Follow-Up Strategy Most tradies lose money not because their invoices are wrong, but because they're sent too late or forgotten about altogether. The ATO expects invoices to be issued when you supply the work or materials—not weeks later when you finally get around to it. If you're sending invoices 30 days after the job's finished, you've already lost cash flow momentum. Here's the practical approach: invoice on the day you finish the job, or the day materials are delivered. If you're doing multi-week projects, send progress invoices weekly. This keeps your client's mind fresh on what they owe, reduces disputes about completed work, and gets payment flowing sooner. For follow-up, most tradies are too soft. If an invoice is due on the 15th and you haven't received payment by the 20th, send a polite reminder the same day. Don't wait two weeks. A simple email saying "Hi [name], just checking you received invoice #1234 dated [date] for $[amount]. Payment was due [date]. Please let me know if there are any issues" takes 30 seconds and recovers thousands across the year. Consider offering a small discount for early payment—2% off if paid within 7 days instead of 30. For a $5,000 invoice, that's $100 in your pocket today instead of waiting a month. Many clients take it, especially if they've got cash on hand. Set yourself a rule: no job handover until payment is received or a payment plan is agreed in writing. This sounds harsh, but it's how successful tradies operate. You wouldn't expect your supplier to give you materials for 30 days without payment—your clients shouldn't get your labour that way either. ## Tax Invoice Requirements: The ATO's Non-Negotiables The ATO is particular about tax invoices. If your invoice doesn't meet the legal requirements, it's not a valid tax invoice—which means you can't claim the GST and your client can't claim input tax credits. This can cost you both money and cause compliance headaches. A valid Australian tax invoice must include: **Essential elements:** - Your name, ABN, and address - Invoice date - Invoice number (and it must be sequential—no gaps or reusing numbers) - Client's name and ABN (if they're registered for GST) - Clear description of what you supplied (be specific: "Labour for bathroom renovation—14 hours @ $85/hr" not just "work done") - Quantity and unit price - Total amount including GST - GST amount separately shown - Payment terms - Your contact details for inquiries The most common mistake tradies make is being vague about what was supplied. "Services rendered" doesn't cut it. The ATO wants to see exactly what you did. "Supply and installation of 12m² porcelain tiles, grout, and labour" is clear. "Tiling work" is not. If you're registered for GST (and if you turn over more than $75,000 annually, you must be), GST must be shown separately. You can't just bundle it into the total price and not itemise it. Your invoice needs to show the subtotal, then GST, then the final amount. For clients without an ABN (sole traders, non-registered businesses), you still need to issue a tax invoice—you just won't include their ABN field. But you must still show GST itemised on your invoice. Keep invoice numbers consecutive and never skip numbers. Use 001, 002, 003, not random numbers. If a client disputes an invoice, you need to be able to show a clear sequence of invoices to the ATO if audited. **Common invoice mistakes and fixes:** | Mistake | Why It's a Problem | Fix | |---------|-------------------|-----| | Vague description ("work done") | ATO considers it invalid; client may dispute charges | Write exactly what was done and hours/quantity | | Missing sequential invoice number | Creates audit red flags; looks disorganised | Number invoices 001, 002, 003 with no gaps | | GST not itemised | Client can't claim input credits; ATO may reject your GST claims | Always show subtotal, then +GST, then total | | No payment terms | Creates confusion; extends your payment timeline | State clearly: "Due within 14 days" or "Due on receipt" | | Invoice issued weeks after work | Violates ATO timing requirements | Invoice on the day work is completed | | Client name but no ABN when they have one | Indicates you didn't verify their details | Ask for ABN when quoting; include on invoice | | Missing your contact details | Client can't follow up if there's a query | Include phone and email for invoice queries | Getting these details right isn't bureaucratic busy-work—it's the difference between legitimate tax deductions and ATO scrutiny. And practically, clear invoices get paid faster because clients understand exactly what they're paying for. --- ## Frequently Asked Questions --- The bottom line: your invoice is your most important business document. It's how you get paid, how you prove your income to the ATO, and how you maintain professional credibility with clients. Spend 10 minutes setting up an invoicing system properly—whether that's a template in Word, a spreadsheet, or proper software—and you'll recover thousands in faster payments and fewer disputes over your career.
