Everything a tradie actually needs. Sorted.

No bloated software. No features you'll never use. Just the stuff that keeps the money coming in and the jobs running smooth.

Quoting

Professional PDFs in seconds

Voice note the details, get a branded PDF quote sent to your client. Itemised, VAT calculated, looking proper professional. Jan handles the lot.

Invoicing

Auto-generated & payment chasing

Quotes convert to invoices with one message. Payment links included. And if they don't pay? Jan chases them so you don't have to have that awkward conversation.

Extras Approval

Get the extra signed off during the job

Avoid the "that'll cost more" chat and eating the cost of scope creep. Send the extra and the client approves in one tap. It's in writing and on the invoice.

Expenses

Snap & log receipts

Photo a receipt, send it to WhatsApp. It all gets logged and categorised, ready for your accountant. No more carrier bag full of crumpled receipts at tax time.

Scheduling & Team Comms

Who's where, when & told first

Book jobs, assign your crew, see your week at a glance. Morning briefs go out automatically — what job, what address, what time. No more 6am calls asking "where am I going today?"

WhatsApp Native

Telegram too — no new apps to learn

It all runs through WhatsApp — or Telegram, if that's the chat you're already in. Voice notes, photos, texts, forwarded emails, receipt snaps — whatever's easiest. The tech just works so you don't have to.

Everything. One screen.

WhatsApp runs the day-to-day. But when you want the full picture — jobs, money, clients, schedule — it's all here. No spreadsheets. No guessing.

Home dashboard — afternoon greeting, beta notice, the money in one line
Jobs list — 18 on the books, filtered by status
Job detail — Replace leaking radiator valve for Dave Wilson, schedule and crew
Money — paid this month, awaiting, overdue
