BUILT A FULL SAAS PRODUCT, TELEGRAM-FIRST.

// THE_CHALLENGE

SPREADSHEETS ARE NOT AN OPERATING SYSTEM.

Small social commerce sellers — running storefronts across Instagram, Facebook, and WhatsApp — are operating full businesses from their phones. They're logging sales in Telegram threads, tracking stock in Google Sheets, and holding customer records in memory. It works, until it doesn't.

Stock drift. Oversell disputes. No profit visibility because cost data lives in a different spreadsheet. No audit trail when something goes wrong. Invoicing done manually in Word. These are not edge cases — they are the daily reality for thousands of solo sellers who need business-grade controls without enterprise-grade complexity.

// WHAT_WE_BUILT

CORRECTNESS FIRST. SPEED SECOND.

AirLedge is built around one principle: stock and financial truth comes from an immutable, append-only transaction ledger — not from mutable fields that any sync or retry can corrupt. Every write is idempotent. Telegram retries cannot duplicate a sale. Every reversal is a compensating entry, not a delete. The ledger is always reconcilable.

The Telegram bot (Deno + grammY) is the primary operational interface — sellers never need to open a browser to log a sale, check stock, or undo a mistake. Structured command flows (/sold, /undo, /setstock, /list, /today) cover the daily 90%. An import flow accepts text or photo lists, parses them into candidate SKUs, routes them through a web mini-app for review, and commits atomically.

The Next.js web dashboard handles everything that needs more screen space: transaction history, filtered exports, customer records, invoice generation and branding, team management, and monthly KPI dashboards. Pro tier unlocks AI-generated weekly reports — revenue summaries, profit analysis, and restock suggestions delivered to Telegram on a schedule.
