Glass dealers & processors
How glass dealers automate sqft billing, quotations and GST with hisabkitab
Picture a glass dealer and processor in Surat supplying float, toughened and mirror glass to fabricators, interior firms and builders. Most orders are cut to size and billed per square foot, with polishing and holes charged extra.

The Challenges
Why glass billing breaks ordinary software
Every cut size is a sqft calculation
Each order has a dozen sizes in inches or millimetres, rounded up to the chargeable size before the per-sqft rate applies. Staff convert, round and multiply on a calculator, and one wrong line of 12mm toughened glass can cost more than the margin on the whole order.
Polishing, holes and cut-outs get missed
Edge polishing is charged by the running foot and holes or cut-outs by the piece. When these extras live on a separate slip, they are the first thing forgotten at billing time, and the work is done for free.
Breakage and offcuts eat stock quietly
Sheets crack in handling and offcuts pile up in the corner. If breakage is never recorded, the stock register keeps showing glass that no longer exists, and the true cost per square foot stays hidden.
Builder credit and site deliveries
Builders and fabricators buy on credit and pay against their own project milestones, while large site loads cross the ₹50,000 e-way bill limit. Dispatch paperwork and collections both end up depending on what the owner remembers.
A Day in the Life
A Day Before vs After hisabkitab
Before
Counter staff write sizes on a slip, round them up and work out square feet on a calculator.
Polishing and hole charges are added from memory, when they are added at all.
The dispatch clerk re-enters invoice values on the e-way bill portal for every site load.
With hisabkitab
Staff enter width, height and pieces; the formula writes square feet into quantity and prices the line at the per-sqft rate.
Polishing by running foot and holes by piece sit on the same quote and invoice as separate lines, so extras are never missed.
E-way bills and e-invoices come from the saved invoice in one click, and Auto-WhatsApp sends payment reminders.
Solutions
How hisabkitab Solves It
Manual sqft calculation
Custom Field (Item Level) + Formula
Add Width, Height and Pieces as item-level fields on glass items. The formula Total Qty = Width × Height × Pieces ÷ 144 fills square feet into the quantity on every purchase and sale line, and the rate per sqft prices it. Staff enter the chargeable size; the maths is done for them.
Missed polishing and hole charges
Estimate/Quote → Invoice
Build the quote with glass, polishing per running foot and holes or cut-outs per piece as separate lines. When the customer approves, convert the quotation into an invoice in one click, so every extra you quoted is an extra you bill.
Breakage nobody records
Stock Journal
Write off cracked sheets and unusable offcuts through a Stock Journal entry. Stock Summary then shows the glass you actually have, and the Item-wise Profit Report reflects the true cost of each thickness.
Builder credit that ages unseen
Customer Ageing + Auto-payment reminder
Every bill is tracked against the builder's or fabricator's ledger. The ageing report buckets dues by days outstanding, and automatic WhatsApp and email reminders go out on schedule, so the owner only calls the accounts that need a personal nudge.
Portal re-entry for e-way bills
One-click e-way bill & e-invoice
Generate the e-way bill and IRN straight from the invoice; values, HSN and GSTINs flow across automatically. The vehicle number sits in a transaction-level custom field, so Part B is ready when the site load leaves.
Inside the Software

Custom Formula Example
Total Qty (sqft) = Width (in) × Height (in) × Pieces ÷ 144. Example: 36 × 72 in × 10 pcs = 180 sqft; 180 sqft × ₹110/sqft = ₹19,800 before GST.
4-Level Grouping
Items: Glass → Toughened → Brand A → 12mm. Customers: Area (Vesu) → Buyer type (Fabricator) → Salesman → Party.

Compliance Notes
Flat glass, toughened and laminated safety glass and mirrors generally fall in the 18% GST slab, but confirm each HSN code because rates were rationalised in September 2025. Consignments above ₹50,000 need an e-way bill, including site deliveries. If your aggregate turnover crosses the e-invoicing threshold, B2B invoices must carry an IRN and QR code, and builder and fabricator buyers rely on your correct GSTIN and HSN data to claim input tax credit.
Recommended Plan
The Plan That Fits
Boost
₹4,999/year, exclusive of 18% GST (or ₹9,999 for 3 years)
Item and transaction custom fields with the sqft formula, quotations, delivery challans and up to 1,500 e-way bills and e-invoices a year cover a single-location glass shop. Processors with heavy site dispatch should look at Advance for unlimited e-way bills, AI-OCR on supplier bills and an Audit Trail.
FAQs
Frequently Asked Questions
Can hisabkitab bill glass in square feet when sizes are in inches?
Yes. Add width, height and pieces as fields on your glass items, and a formula converts the size into square feet on both purchase and sale lines. Enter the chargeable size your shop bills on and the rate per sqft prices the line, while the size stays printed on the invoice for the customer.
How do I bill polishing, holes and cut-outs?
Create them as service items: polishing priced per running foot, holes and cut-outs per piece. Add them as lines on the same quotation or invoice as the glass, so the customer sees each charge and none of them is forgotten at the counter.
How should I record broken sheets and offcuts?
Record breakage and unusable offcuts through a Stock Journal entry. Your stock then matches what is actually in the racks, and the Item-wise Profit Report reflects the real cost of the glass you sold.
Can I move from Tally without losing builder outstandings?
Yes. Export your Day Book and Trial Balance and the Tally Connector brings them in, including opening balances, party outstandings and item stock. hisabkitab migrates your history without charging extra, and we ask you to tick one closed period's Trial Balance against Tally so you know it matches.
