Search "free inventory software" and you'll get a wall of results that all sound the same: free forever, no credit card, unlimited everything. Sign up, and the reality is usually one of two things — a plan capped so tightly it's unusable past a hobby, or a trial with a countdown clock quietly ticking toward a forced upgrade. Neither of those is dishonest exactly, but neither is quite what "free" implies either. This is a plain-language look at what free actually means across this market, what a genuinely useful free tier looks like for a manufacturer, and when free is the right call versus when it's just delaying an inevitable, more painful migration.
The Three Flavors of "Free"
Almost every tool selling itself as free inventory software falls into one of three buckets, and it's worth knowing which one you're looking at before you build your workflow around it.
Item-capped lists. The most common pattern, especially among general-purpose inventory and asset-tracking tools, is a free plan capped at a fixed number of items — commonly somewhere around 100 items, as of mid-2026, though exact caps vary by vendor and change over time. That's fine for tracking office equipment or a small personal collection. For a manufacturer, it evaporates fast: every raw material, every packaging component, every SKU variant, every intermediate product all count against that ceiling. A modest food producer with a dozen recipes can blow past 100 items before they've even added their finished goods.
Time-boxed trials dressed as free plans. The second pattern is a trial — usually 14 to 30 days — marketed with "free" language that implies permanence but isn't. You get full features for a few weeks, then a paywall. There's nothing wrong with a trial; it's an honest way to let you evaluate a product. The problem is when it's presented as if it were a standing free tier, and you don't realize the clock is running until the emails about upgrading start.
Single-user limits. The third pattern caps the free plan at one user account. That works for a solo maker, but the moment a second person — a warehouse lead, a bookkeeper, a co-founder — needs their own login, you're paying, regardless of how many items or transactions you're tracking. It's a reasonable business model, but it's worth knowing upfront if your operation already has more than one person touching inventory.
None of these patterns are inherently bad. They're just different shapes of "free," and the shape matters a lot depending on what stage your business is at.
What a Useful Free Tier Actually Looks Like for a Manufacturer
If you strip away the marketing and ask what a free tier needs to include to be genuinely useful — not a teaser, an actual working tool — three things stand out.
Real finished-goods tracking, not a demo sandbox. You should be able to track your actual products, actual quantities, and actual stock levels on the free plan, not a limited preview that's clearly designed to make you feel the walls closing in after a week.
No expiry date on the plan itself. A free tier that's actually free doesn't have a countdown. It might have feature limits, but the plan itself should persist for as long as you want to use it at that scale — not convert into a bill on day 31.
A visible path forward. As your operation grows past what finished-goods tracking alone can support — you start manufacturing rather than just reselling, you need bills of materials, you need to track production runs, you need lot-level traceability — there should be a clear, known upgrade path, not a scramble to migrate everything to a different platform because the one you started on doesn't scale with you.
Where Nstock Fits
Nstock runs two separate things side by side, and it's worth being precise about the difference because they get conflated constantly. First, there's a free tier: finished-goods tracking, free forever, with no expiry date. Second, and separately, every new account also gets a 90-day full-featured trial of the Business plan — BOMs, production runs, lot tracking, sales quotes, the works — so you can actually put the deeper manufacturing features through their paces before deciding whether you need them yet.
That's both, not either/or. You're not choosing between "the free plan" and "the trial" — you get the trial period to explore everything, and then whatever you don't keep paying for, the free tier catches you: finished-goods tracking keeps working indefinitely, at no cost, no time limit.
To be equally direct about what the free tier does not include: bills of materials, production runs, and lot tracking are paid features, available during the 90-day trial and on paid plans afterward, but not on the free tier itself. If your business is genuinely just manufacturing and selling — no multi-stage recipes, no lot-level compliance requirements — free might be all you ever need. If you're running actual production, you'll eventually need to pick a plan that includes it. See pricing for current plan details.
When Free Is Genuinely Enough
Free fits a specific, real stage of business, not just a budget constraint. It's a good fit if you're early-stage and mostly reselling or lightly assembling rather than running multi-step production, if your SKU count is low enough that finished-goods tracking alone gives you the visibility you need, and if you're not yet tracking production runs, BOMs, or lot-level traceability because your operation hasn't reached that complexity yet.
The signs you've outgrown it are usually obvious in hindsight: you're manually calculating what a batch costs because there's no BOM behind it, you can't answer "how many can we make right now" without checking three different places, or a customer or auditor asks for lot-level traceability and you don't have it. If you're spreadsheet-patching around features a free plan can't provide, that patching has a real cost — usually more in wasted hours than the plan would have cost outright, and The True Cost of Spreadsheet Inventory walks through how to put an actual dollar figure on it. If you're evaluating a move off another tool entirely, switching to Nstock or comparing against something like Sortly is worth doing with the actual limits in front of you, not the marketing copy.

Frequently Asked Questions
Is Nstock's free tier time-limited?
No. The free tier — finished-goods tracking — doesn't expire. It's separate from the 90-day trial and continues indefinitely at no cost.
What's included in the 90-day trial?
Full Business plan features: bills of materials, production runs, lot tracking, sales quotes, and everything else on the Business tier. No credit card is required to start it.
What happens after the trial ends?
You choose a paid plan that fits your operation, or you drop down to the free tier. Either way, your data stays intact — nothing is deleted when the trial ends, and you keep access to whatever the free tier includes without re-entering anything.
