Common Problems

Why Plumbers need a better billing system

📄

No proper bill means delayed payment

Clients who received a professional invoice with a due date pay faster than those who got a verbal quote.

🔢

Calculating GST on labour + pipes + fittings separately is confusing

Different materials have different GST rates. Getting it right matters for both you and your client's accounting.

📱

Heavy desktop software doesn't work in the field

You need billing that works on your phone, at the site, even without internet.

💰

Clients forget to pay without a formal reminder

An invoice with a due date, UPI QR code, and a follow-up WhatsApp is more effective than chasing clients by phone.

How Ozydo Helps

Built for Plumbers — not generic business software

1

Labour + pipes + fittings on one invoice

Plumbing labour (18% GST, SAC 995469) and materials — PVC pipes (HSN 3917), brass fittings (HSN 7412), valves — as separate line items.

2

Offline on any phone

Works without internet on Android and iPhone. Install as a PWA and create invoices on-site, in the basement, anywhere.

3

WhatsApp PDF in one tap

Auto-generates invoice PDF and pre-fills the WhatsApp message. Your client receives it before you leave the site.

4

UPI payment QR code

Add your UPI ID once. A QR code is printed on every invoice — clients pay via any UPI app instantly.

5

Send estimates before starting

Quote the job as an estimate, get approval via WhatsApp, then convert to invoice when work is done.

6

Payment tracking dashboard

See which jobs are paid and which are outstanding. Know your total receivables at a glance.
