Built for the complete accounting cycle
Most accounting apps are either too simple to grow with you, or too complex and expensive. Basis hits the sweet spot.
Every company is a single portable file. Back it up to a USB drive, email it to your accountant, or move it to a new server in seconds. No cloud lock-in, no subscription required to access your own data.
Inspired by Tally ERP: every voucher posts immediately to the General Ledger. No end-of-day batch, no manual posting step. Your Profit & Loss is accurate the moment you save a transaction.
Most cheap tools only do invoicing. Basis covers the complete double-entry accounting cycle: Sales Orders → Delivery Notes → Invoices → Credit Notes, and the full purchase mirror — all linked and tracked.
From the moment a customer places an order to the day you reconcile the payment, every document is connected. No double-keying, no reconciliation headaches.
Real-time financial statements that update the moment a voucher is saved. Export to Excel or PDF with one click.
Track stock across multiple locations, manage production BOMs, run stock opname, and get instant low-stock alerts. WAC costing updates automatically with every movement.
Generate a secure, time-limited magic link for any customer. They can view invoices, download PDFs, check their statement, and leave comments — without creating an account.
From single-user desktop to multi-branch cloud — Basis covers the complete accounting cycle.
