You just finished the job. Now comes the part you hate โ€” the invoice. It's 6pm, you're in the van, and the last thing you want is to thumb line items into a tiny form. So you put it off. A week goes by. Still not paid. Zindow fixes that. Just talk. Say what you did and what you charged โ€” "Replaced the boiler, two hours labour, ยฃ180 in parts" โ€” and Zindow turns it into a clean, professional PDF invoice in seconds. No typing. No fighting with templates. No laptop. BUILT FOR THE TRADE, NOT FOR ACCOUNTANTS Zindow isn't another bloated business app. It's a fast invoicing tool for contractors on site โ€” plumbers, electricians, builders, handymen, and every tradesperson in between. If you can talk, you can invoice. WHY TRADES USE ZINDOW - Speak it, send it โ€” voice-to-invoice gets a finished PDF out before you've left the driveway - Look the part โ€” clean, branded invoices that make you look as good as your work - Know when they've seen it โ€” get a push notification the second your client opens the invoice, so it's never "lost in spam" - Send it their way โ€” fire it straight to your client over WhatsApp, iMessage or email - Add the proof โ€” attach job photos right to the invoice - Stay on top of it โ€” see who's paid and who's dragging their feet in one glance GET PAID FASTER Half the battle is just sending the thing before you forget. Zindow makes it a 30-second job you do on the spot, while you're still standing in the customer's kitchen. Out faster means paid faster. NO MORE SHOEBOX Every invoice is saved and organised automatically. Tax time stops being a glovebox full of crumpled receipts. MADE FOR THE JOB SITE Big buttons. Text you can read in the sun. Zindow is built for the van and the site, not a desk. Stop losing your evenings to paperwork. Start invoicing with your voice. Download Zindow and send your first invoice before you leave the job.
