Definition
Voice invoicing is the process of describing a completed job out loud and having software automatically build a structured, priced invoice from your speech. Instead of opening an app and typing, you speak — the software transcribes and interprets what you said, then generates a tax-compliant invoice ready to send to your customer.
Voice invoicing eliminates the single biggest reason tradespeople and contractors fail to invoice on the day: the friction of typing. When you can describe a job the same way you'd explain it to a mate — and have the invoice ready in under a minute — invoicing on the day becomes the default, not the exception.
The term covers both voice-to-invoice (converting speech directly into an invoice) and voice-to-quote (building a quote or estimate from spoken job descriptions). In practice, the same technology handles both.
Why it matters
Tradies and contractors have always known what needs to be invoiced. The problem was never the work — it was the paperwork.

Not because the jobs weren't done. Because invoicing felt like too much effort after a full day on site.

Faster than typing an invoice manually
Typing a standard invoice takes 8–15 minutes. Describing it takes 30 seconds. Voice invoicing removes the gap entirely.

From job done to invoice sent
Speak. Review. Send. The entire process — including GST calculation and customer delivery — in under a minute.
Who uses it
Voice invoicing works for any trade or service business where jobs are quoted and invoiced on site — not at a desk.
How it works
This is the complete workflow — from the moment you finish a job to money in your account.
Describe the job out loud — what you did, materials used, time taken. 20–30 seconds. Natural speech, no script.
In under 10 seconds, a structured, priced, GST-compliant invoice is built automatically from your speech.
Review the invoice, make any edits, then send it as a link via SMS, email, or WhatsApp. Instant delivery.
Customer opens the link on their phone. You're notified the second they open it. They approve with one tap.
Payment processed immediately. Money on its way. Invoice automatically issued. Total time: under 60 seconds.
Total time from job done to invoice sent: under 60 seconds
How SMASH does it
Voice invoicing at this speed requires four systems working together.
SMASH uses professional-grade voice transcription tuned for trade terminology, Australian accents, and noisy environments. You don't need to speak slowly or use special words. Say it the way you'd explain it to an apprentice.
The transcription is processed by an AI model trained to identify line items, labour time, materials, rates, and customer details from natural job descriptions. It fills gaps intelligently using your pricing catalog and job history.
Build your rates once and SMASH remembers them. Every time you mention a service or material you've quoted before, it fills the price automatically. The more you use it, the faster it gets — under 30 seconds once your catalog is established.
Every invoice generated by SMASH is automatically GST-compliant — ABN included, tax calculated correctly, line items itemised. Meets ATO tax invoice requirements for Australian businesses without any extra steps.
Real examples
No special format. No specific words. Just the job, the way you'd explain it.
"3-bed standard clean, Mrs Johnson, Indooroopilly, took about 3 hours, the usual rate."
Quote built: 3hr standard clean, correct rate, GST included, customer link ready.
"Fixed the fence gate out the back — two new hinges and a latch, about 2 hours labour."
Quote built: labour + materials priced from catalog, sent in 45 seconds.
"Bedroom and hallway, 2 coats, used about 15 litres of paint, took 2 days."
Quote built: paint materials priced, labour rate applied, PDF ready.
The only real difference is whether you type or talk.
