Inventory management software for free: the honest ladder

The ladder, in one view

• Rung 1 — the spreadsheet: genuinely free forever; one person, few hundred SKUs, discipline required.
• Rung 2 — open source and free tiers: software without a licence fee; setup, limits and maintenance are the cost.
• Rung 3 — the free trial: the full product, free for a testing period; the honest way to decide.
• Rung 4 — the paid plan: where the workflow joins up and someone else runs the record.
• The wider system: inventory management end to end maps the whole record this page sits in.

What each rung actually gets you

The spreadsheet is the only truly free inventory software. It records; it does not allocate, enforce or share. For one person with careful habits it is a legitimate operating tool, and this page will not rush you off it. Open source and free tiers put real software under you: real records, no licence — paid for in setup hours, hosting or caps, and weakest exactly at the seams (accounting handoff, scanning, portals). The free trial is the most underused rung: a full product, free, that tests the joined workflow — allocation, purchasing, invoicing, the handoff to Xero or MYOB — against your actual products before any money moves. The paid plan is what the trial converts to when the fit is real; its fee buys the joining, and someone else running the record.

The crossover is not company size; it is the first structural failure — an oversell, a two-person collision, an order lost between systems. The free stock software guide prices that crossover, and the basic tools cover the bottom rung.

What free never includes

Name it once, plainly: no free option gives you the joined record — stock that orders allocate from, purchasing that answers demand, a portal customers order through, invoicing that hands off to the accountant, and history behind every number. That joining is the product, everywhere in this market, because it is the thing that is expensive to build and run. Free paths are honest about holding a record; the paid category is about holding the record every part of the business reads.

So use free for what it does: the spreadsheet while volumes are low, the trial to see the joined version with your own data, and the paid plan when the fit is proven — not before, and not out of feature FOMO. BSimple sits on the top rungs: a free trial, then plans from $180/month (AUD) with everything included. It is not free software and does not pretend to be.
