How to invoice a customer from your phone as a tradie

The actual friction

Most tradies already have an invoicing app. ServiceM8, Tradify, Xero — the tools exist, and plenty of people use them well. The problem isn't mobile access. It's that invoicing happens in a different app to the one you're already in when the job wraps up.

The conversation with your customer happened on WhatsApp. The quote confirmation was in WhatsApp. You're back at the van, WhatsApp open. The next step is to close it, find the invoicing app, create a new job, enter the customer details, describe the work, add the amount, and send. It's not a massive task — but it's enough of a context switch at the end of a long day to push it to tonight. Tonight becomes tomorrow. Tomorrow is a full day at another job. By the time the invoice goes out, it's three to five days after you finished the work.

Three to five days doesn't sound like much. But across 10 to 15 jobs a month, that delay compounds quickly. Money that should be landing in your account this week sits uncollected while you're already spending on the next job. The gap between work done and cash received is almost always an invoicing lag — not a payment problem.

How it works with Korda

Korda lives inside WhatsApp — the app you're already in. When the job's done, you send a voice note: "Invoice for Mark at 14 Birchgrove Road, bathroom reno, $4,200 including GST."

Korda transcribes it and drafts an invoice. It sends that draft back to you to review. You check the details, make any changes, approve it, and it goes to your customer. The whole exchange takes about thirty seconds. The invoice hits their inbox and flows automatically into Xero — no separate login, no double entry, no reconciliation headache later.

The approval step is deliberate. Nothing goes to your customer without your approval. You're still in control of every invoice — Korda just removes the friction of building it from scratch.

Why sending it to the job changes your cash position

The closer to the job, the easier the collection. A customer who receives an invoice while you're still in their street is mentally inside the transaction — the work is fresh, the result is visible, and the goodwill is at its peak. A customer who receives an invoice four days later has moved on. They'll pay it, but it takes longer, and any follow-up conversation is less comfortable for everyone.

Beyond individual jobs, staying current with invoicing gives you an accurate view of where your business actually stands. Korda's Morning Brief arrives at 7am every day, showing your collected, outstanding, and overdue revenue — so you know your cash position before the first job of the day. No mental maths, no spreadsheet three weeks behind, no end-of-month surprises.
