Software that replacespaper, Excel and WhatsApp.

Ledgers lived in paper books that got lost or torn, so nobody could answer “who owes me what?” without digging through a register. Handwritten quotations were slow to turn around, and statements were shared as awkward screenshots. There was no single view of outstanding payments across locations, and reconciliation was a manual, error-prone job.

We rebuilt the whole workflow as two installable PWAs with one shared design system. Ledgr keeps every book behind an OTP, splits dues into ageing buckets for an at-a-glance picture, and fires a branded A5 statement by SMS or WhatsApp in one tap — plus a visit-day planner so you call on the clients who actually owe you. Quotio composes GST-ready estimates on the client's real A5 letterhead, pulls prices from a product master, and shares them as auto-numbered quotes with a rich WhatsApp card and PDF. Bulk statements and reminders go out with zero SMS bill by turning a spare Android phone into the gateway — tested end-to-end in the field. The backend runs FastAPI + PostgreSQL, and the apps install and run offline where the business actually works.

Diagnostic labs run on a patchwork of paper registers, Excel sheets and disconnected software. There is no single view of pending cases, no automated approval workflow, and daily cash — denominations, expenses, receivables and handover — is reconciled by hand. Reporting out to management is a slow, manual job.

We rebuilt LabDesk as a dark-first SPA on a clean REST API. Patient registration, test assignment, result entry, approvals and accounting all live in one cohesive app with role-based access, six dashboard charts (cases by month, collections vs expenses, revenue by referring doctor, most requested tests, case classes and denomination breakdown), and a white-label brand layer that keeps the institute's identity on screen. MIS exports to Excel via ClosedXML in one click.
