You do the work. SMASH does the rest.
Joist is a well-known contractor app for estimates, invoices, and getting paid. It is still a tap-and-type product. SMASH competes for the same ICP with a different input and a tighter loop: voice against your rates → send → they approve → they pay — before you leave the driveway.
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 | Joist | |
|---|---|---|
| Win the job (quote / estimate) | Talk → priced PDF on site (~30s) | Mobile forms / line items |
| Customer approves | One-tap approval link | In-app client flow |
| Invoice same lines | Convert — no retype | Convert in Joist |
| Get paid | Pay on the same link | Joist payments |
| Dirty-hands capture | Voice on iPhone | Minutes of tapping |
| Prices | Your catalog — nothing guessed | Item library you maintain |
| SMASH | Joist | |
|---|---|---|
| Build estimate | Voice → catalog match | Mobile forms / line items |
| Speed on site | ~30 seconds talk → send | Minutes of tapping |
| Full money loop | Quote → approve → pay | Strong — still form-based |
| AU GST / ABN focus | Native multi-market tax | US-strong roots; check AU fit |
| Gmail quoting | Chrome extension | App-first |
| Free start | Yes | Freemium / paid |
If someone googles “Joist alternative,” they already buy contractor software. The pitch is not “another job suite.” It is: keep life simple, stop typing estimates, send before the customer messages the next bloke. First quote wins. Same story as Invoice2go and Invoice Simple switchers.
Joist works when you have time to build the estimate. On a handyman day — five sites, dirty hands, customer waiting at the van — the open tab becomes “type it tonight.” SMASH’s product promise is the opposite: every job different, every invoice in 60 seconds. Talk. Verify. Out the door before you are.
Joist covers estimates and payments. SMASH optimises the dirty-hands capture and the same approval portal after voice. You do not need a full field-service OS to get paid today — compare ServiceM8 and Tradify if you are weighing suites.
Joist plans vary by region — verify current pricing. SMASH free + paid from ~$15/month AUD. SMASH pricing.
Solo contractors and small crews who liked Joist’s simplicity but want voice + catalog pricing — and a loop that finishes with approve and pay on site.
If the open tab is still “type the estimate later,” SMASH is the hijack.
Both cover quote → invoice. SMASH optimises for dirty-hands capture via voice to invoice.
Both can collect payment. SMASH ships approval + pay on the customer link after a catalog-priced send.
Yes for sole traders who want faster on-site quoting by voice with their own rates — and the approve/pay loop without more forms.
No. SMASH is the speed layer for quote and invoice. Job scheduling suites can sit beside it.
Contractor app. Without the keyboard.
Quote the next job by voice.
