Invoicing Software for Tradies NZ — Get Paid Faster with Xero Integration

Xero is excellent accounting software, and nearly every NZ trade business uses it (or should). But using Xero alone for invoicing creates a disconnect: you track jobs in one system (or on paper) and create invoices in another. Every invoice requires manually typing the customer details, job description, and line items — all of which already exist somewhere in your job records.

Dedicated trade invoicing — through a job management tool that connects to Xero — eliminates this duplication. When a job is marked complete, the invoice is generated automatically from the job record: customer details, address, line items, and totals all flow through. You review it, click send, and it appears in Xero as a tracked invoice.

The time saving is real. Most trade business owners spend 3–5 hours per week on invoicing. Connected software can cut that to under an hour. More importantly, invoices go out faster — the same day the job is done rather than the end of the week — which directly improves cash flow.

Two-way Xero sync (offered by ATT, Tradify, and Fergus) is the key feature. One-way sync pushes invoices to Xero but doesn't bring payment status back. Two-way means you can see in your job management tool which invoices are paid, overdue, or outstanding — without switching to Xero to check.

When evaluating invoicing software for a trade business, these features separate useful from inadequate:

• Quote-to-invoice conversion: The number one time-saver. When a quoted job is complete, you should be able to convert the quote to an invoice with minimal editing. No retyping line items or customer details.
• Two-way Xero sync: Push invoices to Xero and pull payment status back. This means your job management tool always shows current payment status alongside job records.
• Progress invoicing: For jobs over $5,000 (common for house painting, renovations, commercial work), billing in stages — deposit, progress claim, final — is essential. Your tool should support creating multiple invoices against one job.
• GST-exclusive pricing: Trade-to-trade invoicing in NZ is typically GST-exclusive. Residential work is often GST-inclusive. Your tool should handle both and calculate GST correctly.
• Supplier invoice tracking: For job costing, you need to assign supplier invoices (paint, materials, equipment hire) to specific jobs. ATT's AI invoice scanning reads supplier invoices and suggests job allocation.
• Overdue invoice tracking: Knowing which invoices are 7, 14, or 30+ days overdue — and which customers are slow payers — helps you manage cash flow proactively.
• Batch invoicing: If you complete multiple small jobs in a week, being able to invoice them all at once rather than one by one saves time.

If you're currently using Xero alone for invoicing, adding a connected job management tool is the single biggest efficiency gain most trade businesses can make. See our quoting and invoicing software guide for a broader comparison.

If you're not ready for paid invoicing software, a well-structured invoice template is a good starting point. We've published a free painting invoice template for NZ that includes all the required elements:

• Your business name, GST number, and contact details
• Customer name and job site address
• Clear line items with quantities, rates, and descriptions
• Materials and labour separated (useful for customer transparency)
• GST calculation (exclusive and inclusive totals)
• Payment terms and bank account details
• Job reference number for your records

The template works in Google Docs, Word, or Excel. It's adequate for sole traders doing a few jobs per month. The limitation is obvious: every invoice is created manually from scratch, and there's no connection to your quoting or accounting system.

Most businesses outgrow a template when they hit 8–10 invoices per month. At that point, the time spent on manual invoicing (plus the risk of errors) justifies the cost of proper software. ATT's Quoting plan at $99/mo is a natural step up, with the Professional plan ($199/mo) adding full Xero invoicing integration.

ATT handles invoicing through its Xero integration on the Professional plan ($199/mo NZD excl. GST). Here's the practical workflow:

Quote to invoice: You build a quote in ATT (with Mate AI assistance if needed), send it to the customer, and they accept it digitally. The quote converts to a job. When the job is complete, you generate an invoice from the job record — all line items, customer details, and pricing carry through. The invoice pushes to Xero automatically.

Two-way sync: Once the invoice is in Xero, any updates flow back to ATT. When the customer pays (and Xero records the payment via bank reconciliation), ATT shows the job as paid. You can see outstanding invoices across all jobs without opening Xero.

Progress invoicing: For larger painting jobs, you can create multiple invoices against a single job — a deposit invoice when the job is confirmed, progress invoices at milestones, and a final invoice on completion. Each pushes to Xero separately and tracks independently.

AI invoice scanning: When you receive a supplier invoice (paint order, scaffold hire, equipment rental), ATT can scan it and suggest which job to allocate the cost to. This improves job costing accuracy without manual data entry.

For the full picture of how ATT's quoting and invoicing work together, see our quoting and invoicing software page. For painters specifically, the painting business software page covers how ATT handles painting-specific workflows end to end.

Software speeds up invoicing, but good invoicing habits matter just as much:

• Invoice on the day the job is complete. The longer you wait, the longer you wait to get paid. Same-day invoicing is the single most effective cash flow improvement for trade businesses.
• Set clear payment terms upfront. 7-day terms for residential, 20-day for commercial (or whatever your standard is). Include these on the quote and the invoice. Don't be vague.
• Take deposits on larger jobs. A 30–50% deposit on jobs over $3,000 is standard practice for NZ painters and protects your cash flow. See our guide on painting business profit margins for why this matters.
• Separate materials and labour on invoices. Customers appreciate transparency, and it helps you track your actual margins on labour versus materials. If you're using Resene or Dulux, noting the brand builds confidence.
• Follow up on overdue invoices systematically. Send a reminder at 7 days overdue, a firmer reminder at 14 days, and escalate at 30 days. Xero can automate the first reminder. Don't let invoices age beyond 60 days without action.
• Track your debtor days. Average debtor days (how long customers take to pay) is a key business health metric. Under 20 days is excellent for residential trade work. Over 40 days indicates a problem with either your customer base or your follow-up process.
