§01 — The system

Built around how
glass is actually quoted.

Generic invoice apps treat glass like a line item. Kanch treats it like a measurement — fractions and all — and runs the same chargeable, polish, and area math you've been doing on paper.

§01.01

Inches & mixed fractions, natively.

A dedicated numeric keypad with a ½ key. Type 36 3/16 and Kanch handles the math conversions, area, totals without sending you to a calculator.

36 3 16
Actual L ↳ 36.1875 in
§01.02

Chargeable rules, the way you bill.

Round up. Add fixed inches. Snap to multiples of 3. Set a rule per glass type and every row gets the chargeable dimension your customer expects.

§01.03

Polish, holes, cutouts — priced in.

Polish on L, B, or both running feet auto-converted to square feet. Per-hole and per-cutout pricing on the same row. No spreadsheet gymnastics.

§05 — Questions

Things glass
people ask us.

Can't find what you're looking for? Email kanch.help@gmail.com — we read every message.

Q.01 Does Kanch handle mm and inches in the same invoice? +
Yes. Toggle units per invoice — the chargeable rules, polish, and rate calculations all follow the unit you're working in. Inches accepts mixed fractions (e.g. 36 3/16); mm accepts decimals.
Q.02 How do chargeable dimension rules work? +
Per glass type, define how the actual cut becomes the billed dimension: add a fixed value (e.g. +2″), round to a multiple of N, set a minimum, or combine the three. Kanch applies the rule to every row and shows both actual and chargeable side by side.
Q.03 Will my data sync across devices? +
One Kanch account works on multiple webs. Invoices, customers, glass catalog, and company details sync in real time. Network drops won't lose your work — pending edits flush on reconnect.
Q.04 Can I add my logo, GST, and UPI details to PDFs? +
Yes — company profile holds your logo, address, GSTIN, bank details, and UPI ID (with QR code). Every PDF Kanch generates includes them, along with a calculations footer your customers can verify.
Q.05 Is there a free trial? +
Open the web app and start invoicing — no card, no signup wall for 30 days. Paid plans start at ₹2199/month after the trial ends.
Q.06 Can I import my existing customers and glass rates? +
Paste from any spreadsheet. The 15-column grid accepts the same copy-paste shape as Excel and Google Sheets.
