Business software built on the sheet
you already trust.
CheckBook Softwares designs customized, offline and affordable spreadsheet-based systems — from data & stock management to full workflow automation. One-time cost. No subscriptions. Your data never leaves your device.
Four columns of work, one connected system.
Every engagement starts with the same sheet-based foundation, then branches into whichever of these your business needs most.
Customized Software
Billing, accounting and reporting systems built spreadsheet-first and shaped around how your team already works — not the other way round.
Offline Software
No internet dependency, no server rent, no cloud outages. Your files and records stay on your own device, under your own control.
Data & Stock Management
Real-time stock ledgers, purchase & sales tracking, low-stock alerts and reorder sheets that update themselves as you work.
Automation & Affordable Systems
Formula-driven workflows that remove repetitive data entry — delivered at a cheap, one-time cost with no recurring bills.
From a phone call to a finished system.
Understand your workflow
We talk through how your business currently runs — on paper, in registers, or in scattered sheets — before writing a single formula.
Build & customize
Your system is built directly on the spreadsheet engine, tailored to your exact items, categories, staff and reports.
Deploy, train & support
We install it on your device, train your team, and stay on WhatsApp for support long after handover.
