Stock management software for free

The key facts

• Stage 1, free and legitimate: a spreadsheet — one person, modest products, quantities updated when stock moves.
• Stage 2, capped: free tiers of paid tools — real structure, but caps and paywalls sit exactly where growing businesses need the next feature.
• Stage 3, the fork: open source you host, or a paid system — ownership versus subscription, and both are honest.
• BSimple's position: paid, $180/month AUD up, full-product trial — and no criticism of the free stages; they exist for a reason.
• Context: the full inventory system holds the wider system, this page one stop in it.

What free covers — genuinely

A spreadsheet handles the core of stock management: what you hold, what you had, what moved this week. For one person who updates it the moment stock moves, it is not a compromise — it is a working system, and thousands of businesses run on one for years. Free tiers of paid products add structure: a product list, an app for the warehouse, maybe a scan. The caps are the business model — order volume, user counts, or the accounting export — and they are usually placed exactly at the next stage of your growth.

What free does not cover, at any stage, is the hard part of stock management: concurrent truth. Two people selling the last unit, quantities that deduct the moment an order commits rather than at end-of-week reconciliation, and a history with evidence — who received it, who sold it, who counted it. That layer is where paid systems live, because it is where engineering and accountability are real.

Where each free option stops

• Spreadsheet: the second person editing it. Merged copies and stale quantities are not a spreadsheet failure; they are a concurrency failure it cannot solve.
• Free tier: the first cap you hit — usually orders per month or the accounting export. Hitting one cap means others are close.
• Open source: the day the maintainer leaves. Hosting, patches and backups are real work; the free and open-source picture prices that honestly.
• Paper: immediately after the first discrepancy you cannot explain — which is the point of the record.

The pattern in the free-to-use ladder: each stage is right until the day it is not, and the day announces itself as a cost — an oversell, a re-key, a stocktake that surprises everyone.

BSimple's rung, stated plainly

We build BSimple, so weigh that: it is paid, not free. Plans run $180/$250/$399 per month AUD with every feature in the core plans — live quantities across locations, orders deducting stock on approval, purchase orders raised from demand, batch and expiry tracking, stocktakes, and the accounting handoff to Xero or MYOB with payment status mirroring back. The full-product trial exists because stock software is only worth judging against your own products: load them, receive, sell, count — an afternoon tells you whether the record holds.

What the comparison comes down to: free stages cost hours and forgive errors; the paid stage costs money and prevents them. The crossover is visible in advance — the second person, the second location, the first oversell — and honest businesses cross it at different times. Stock management software, the category shows what the paid layer contains in full, and free stock and inventory tools for PCs covers the budget end.
