You do the work. SMASH does the rest.
Invoice Simple is a solid phone invoicer — tap fields, pick a template, send a PDF. That is half the job. Handymen, cleaners, and mobile trades lose work when the *estimate* never leaves the driveway, or when approval and payment are a separate chase. SMASH was built for the moment the customer is still standing there: talk for about 30 seconds, verify your rates, send, they approve, they pay.
Talk → verify your rates → send → they approve and pay.
Most invoice apps stop at send. Service businesses need quote → approve → invoice → paid — on site.
| SMASH | Invoice Simple | |
|---|---|---|
| Win the job (quote / estimate) | Talk → priced PDF on site (~30s) | Typed estimate / invoice forms |
| Customer approves | One-tap approval link | Email PDF — chase verbally |
| Invoice same lines | Convert — no retype | Convert or rebuild |
| Get paid | Pay on the same link | In-app / link (plan-dependent) |
| Dirty-hands capture | Voice on iPhone | Tap forms on phone |
| Prices | Your catalog — nothing guessed | You type every rate |
| SMASH | Invoice Simple | |
|---|---|---|
| Create quote / invoice | Speak it (~30s) | Tap forms on phone |
| On-site send | Built for the driveway | Possible but slow |
| Approval portal | Yes — one link | Usually just a PDF |
| Gmail desk path | Chrome extension | App-first |
| Xero / QuickBooks | Paid plans | Limited / export-style |
| Free to start | Yes — monthly allowance | Freemium / paid tiers |
It is rarely because Invoice Simple is “bad.” It is because five jobs a day means five rounds of tapping descriptions, quantities, and GST — and the estimate still waits until tonight. Tonight never comes. That is how handymen leave $95 jobs uninvoiced and lose the next booking to whoever replied first.
SMASH removes the form. You talk the scope the way you’d tell a mate. Labour, materials, call-out and travel come from your rates. Unknowns are flagged — not silently invented like ChatGPT. Then the customer gets a link: approve, pay. You see when they open it.
A typical handyman afternoon is not one clean invoice. It is flat-pack in Mosman, a gate latch plus Bunnings bits, then three odd jobs for a property manager. Invoice Simple can bill each one — if you sit in the ute and type. SMASH is built so six small jobs leave with you: speak, verify, send, next driveway. See voice to invoice and first quote wins.
Both apps target freelancers and service businesses. Invoice Simple’s job is a nice invoice PDF. SMASH’s job is the money loop: AI estimates from your catalog → approval → invoice → paid — on iPhone on site, or from Gmail at the desk. If you are also eyeing Joist, Wave, or Invoice2go, it is the same fork in the road.
Invoice Simple uses freemium / subscription tiers that change by market — always check their site. SMASH: free monthly quote/invoice allowance with the full voice workflow, then paid from about $15/month AUD for higher volume and accounting sync. See SMASH pricing.
Handymen, cleaners, gardeners, painters, mobile mechanics — anyone who already tried a “simple” phone invoicer and still hates typing on site. If your backlog is Sunday admin, you are the customer.
If typing is why invoices wait until Sunday — or why quotes never leave the driveway — switch the capture layer.
Both can estimate. SMASH prices from your catalog by voice and is built so the PDF leaves before the customer messages the next bloke.
Invoice Simple can collect payment. SMASH ties approval + pay into one customer link after a voice-built document — out the door before you are.
