Tillqorin — POS & Commerce OS for Retail

The challenge

Retail and wholesale shops often run on disconnected tools — a cash register or spreadsheet for sales, another notebook for purchases, and no single view of stock, customer balances, or daily profit. Off-the-shelf POS suites can be expensive, desktop-bound, or a poor fit for local workflows like Urdu receipts, barcode label printing, and credit customer ledgers. Staff turnover makes training painful when every module looks different. Owners lose hours reconciling cash drawers against handwritten ledgers, and seasonal stock swings go unnoticed until shelves are empty. We needed one fast web application our studio could ship, dogfood, and extend for real counter operations — not a slide-deck prototype that falls apart the first time a barcode fails to scan during rush hour.

Our solution

Tillqorin is a full commerce workspace: manual and touch sales order entry with barcode scanning, purchase posting, product and stock management, accounts (customers, suppliers, banks, staff), expense and cash tracking, exportable ledger reports, and an analytics dashboard for revenue, costs, and net profit trends. Receipts support thermal rolls (58mm / 80mm), A4/A5 invoices, store branding, and QR verification — deployed on pos.taylancetech.com with a Supabase-backed API. Every sale, purchase, and expense posts to the same ledger so reports always reconcile with what the counter recorded. Role-based access lets owners see profit while cashiers stay focused on checkout.

How we approached it

• We modeled the core retail loop first: sell → update stock → record customer balance → print receipt. Purchase and expense flows reuse the same accounts and reporting layer so training one screen teaches the pattern for the rest.
• The UI is optimized for counter speed — keyboard shortcuts, held invoices, credit sales, multi-pay splits, and draft recovery if the browser refreshes mid-sale. Touch targets and font sizes were tested on low-end Android tablets common at shop counters.
• PostgreSQL sequences and Supabase auth keep invoice and order numbers consistent across devices; Vercel hosts the SPA and API on Taylance Tech subdomains with environment separation for staging receipts.
• Barcode label printing and Excel exports were built against real supplier catalogs — mixed SKU formats, duplicate barcodes, and partial case packs — so the first client deployment did not require a custom data migration script.
