You do the work. SMASH does the rest.
Wave wins on price: free invoices and basic accounting for freelancers. The catch for mobile service businesses is the same as every desk tool — you still type line items later, and the estimate often never left the site. SMASH hijacks that moment: talk the job, 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.

Wave is often the first app after Excel — classic ICP. The switcher query is “Wave alternative” when receipts pile up or invoices go out late. SMASH is not trying to replace Wave’s books. It replaces the typing bottleneck with voice to invoice, then syncs to accounting on paid plans. Same fork as FreshBooks and Zoho Invoice.
Books matter. Getting the quote out while the customer is still there matters more for cash flow. Six small jobs × “I’ll Wave it tonight” is how uninvoiced work adds up. SMASH’s loop finishes with approve and pay — then you can sync. See for handymen.
Wave’s core invoicing is free; payments and extras are paid — verify on Wave. SMASH: free allowance, then paid from ~$15/month AUD. SMASH pricing.
Freelancers and sole traders who outgrew “I’ll invoice tonight on Wave” and need driveway-speed sends with approval and pay.
Keep Wave for books if you want. Use SMASH when the customer is still standing there.
Wave is desk-first. SMASH is job-first — speak, verify, send, then sync.
