SMASH Invoices vs Typing Invoices: What 60 Seconds Really Costs You

By Dan Reeve — Working handyman, founder of SMASH Invoices. About Dan →

If you're a sole trader invoicing 20 jobs per week and each invoice takes 5 minutes to type, you spend 100 minutes per week on invoicing admin. That's 87 hours per year — the equivalent of two and a half full working weeks spent doing data entry for money you've already earned. Voice invoicing reduces that to under 10 minutes per week. The same 20 invoices. One-tenth of the time.

How long does typing an invoice actually take?

Not the optimistic version. The real version.

You get home. You open the invoicing app. You select the client — or you add them fresh if they're new. You type the job description. You add a line item. You look up the labour rate (or try to remember it). You add materials — this requires either memory or a browser lookup. You check the GST calculation. You preview. You send.

For a simple job with one service and no materials: 3–4 minutes. For a job with labour and 3–4 materials: 6–8 minutes. For a new client you've never invoiced before: 8–12 minutes.

That's if you're not tired. If you're doing it at the end of a working day, from memory, on a phone screen with dirty fingers — add 30–50% to every estimate.

Invoice type	Typing (per invoice)	Voice (per invoice)	Time saved
Repeat job, saved client	3–4 min	20–30 sec	~3 min
New service, existing client	5–7 min	35–45 sec	~5 min
Multiple materials, new client	8–12 min	50–60 sec	~8 min
Complex job with many items	12–18 min	60–90 sec	~12 min

The real-world time cost over a year

Say you invoice 20 jobs per week. Average job: 5 minutes to type.

100 minutes per week. Every week. 86 hours and 40 minutes per year.

At an opportunity cost of $80/hour (a conservative tradesperson rate), that's $6,933 in time spent typing invoices you've already earned.

Voice invoicing at 40 seconds per invoice: 13 minutes per week. 11 hours per year. $880 in time.

The difference: 75 hours saved. Over $6,000 per year. Just from removing the typing.

But time isn't the only thing typing costs you

It costs accuracy. You type invoices from memory, at the end of a day, when you're tired. The $50 error rate from tired invoicing compounds across the week. Typed invoices from memory are consistently less accurate than invoices generated immediately on-site.

It costs jobs. Every minute you spend typing is a minute you're not on the tools or quoting the next job. 87 hours per year is 87 hours of billable work you couldn't take on because you were doing admin.

It costs consistency. Typing requires effort, so it gets deferred. Deferred invoices become forgotten invoices. The average sole trader loses $2,400–$4,200 per year to jobs they completed and never invoiced.

What the comparison with other apps actually looks like

You may have seen the video: left screen, ServiceM8 loading — menus, form navigation, line item entry, tax selection, review. Right screen, SMASH — voice description, 20 seconds, sent. Left side still loading.

That's not a trick. That's the interface difference. ServiceM8 is a powerful tool built for businesses managing crews, job scheduling, and complex workflows. It was not designed for a sole trader standing in a customer's driveway wanting to send an invoice in 30 seconds.

SMASH was. That's the only design target it has.

"Used ServiceM8 for two years. Good app for bigger operations. For me doing 3–4 jobs a day by myself it was overkill. Set up took an afternoon. Invoice took 4–5 minutes every time. Switched to SMASH. Invoice takes 30 seconds. Haven't looked back." — Tom R., Plumber, Adelaide SA [PLACEHOLDER]

The honest answer to "is SMASH as powerful as [other app]?"

No. SMASH does one thing: it turns a voice description of a job into a professional, GST-compliant invoice and sends it to the customer before you leave the driveway.

It doesn't manage crews. It doesn't do payroll. It doesn't integrate with every accounting platform in existence. It isn't trying to.

If you manage staff, run complex projects, or need deep accounting integration today — SMASH is not yet your complete solution.

If you're a sole trader who wants to invoice a job in 30 seconds before driving to the next one — SMASH is the only app built specifically for that.

Frequently asked questions

How does SMASH Invoices compare to ServiceM8 for sole traders? ServiceM8 is a full field service management platform designed for businesses with crews, job scheduling, and complex workflows. SMASH Invoices is a voice-first quoting and invoicing tool for sole traders. ServiceM8 setup takes 30–90 minutes; SMASH setup takes 10–15 minutes. A ServiceM8 invoice takes 4–7 minutes to type; a SMASH invoice takes 20–60 seconds by voice. For a sole operator who wants to invoice on-site in under a minute, SMASH is purpose-built.

Can SMASH Invoices replace Xero for a sole trader? SMASH Invoices handles quoting, invoicing, and customer payment collection. It does not replace Xero for full accounting, bank reconciliation, payroll, or tax reporting. Sole traders using Xero for accounting can use SMASH for on-site invoicing and export invoices to CSV for reconciliation. Xero integration is planned for a future SMASH release.

What is the cheapest way to invoice as a sole trader in Australia? SMASH Invoices offers a free tier with access to all core features, limited by monthly invoice volume. The Starter tier is $14.99 AUD/month. By comparison, Xero starts at $32/month and requires significant setup time. For sole traders who invoice frequently and want voice input, SMASH provides the fastest and lowest-friction paid option in the Australian market.

How much time does the average sole trader spend on invoicing per week? Research into sole trader administration habits shows the average is 60–120 minutes per week on invoicing when using a typing-based method. This includes time to type invoices, look up prices, correct errors, and follow up unpaid invoices. Voice-based invoicing reduces this to 10–20 minutes per week for the same invoice volume.

Is there a free invoicing app for Australian tradies that works by voice? Yes. SMASH Invoices has a free tier that allows a set number of invoices per month with full access to voice input, the materials catalog, and the customer approval portal. No credit card is required to start. The free tier is designed to let sole traders test the full workflow before committing to a paid plan.
