Most small teams pay $0 to about $150 a month for inventory software — if they avoid two traps: per-seat pricing and intro rates that jump at renewal.
The short answer, in dollars
For a small team, real-world inventory software lands between $0 and roughly $150 per month. The free end is a genuine plan — StockZip is free forever for 100 items, and Sortly and Zoho both offer a free tier — and $100 to $150 a month buys a full operations plan with orders, users, and higher item limits. Anything above that is usually an enterprise suite or a plan padded with per-seat and per-order add-ons.
The number that matters is not the advertised price. It is the price you pay in year two, after intro discounts expire and your team and order volume grow into the next tier. Every figure below is a published rate as of July 2026, quoted from each vendor’s own pricing page, so you can re-check it yourself.
The two traps that inflate the bill
Trap one is per-seat pricing. A plan that looks cheap at $10 a user becomes a real budget line the moment you add a warehouse crew — five seats is $50, ten is $100, and the price scales with headcount rather than with the value you get. Flat-rate plans that bundle a user allowance (StockZip Pro includes eight users) protect you from that curve.
Trap two is the intro-then-renewal jump. Several vendors advertise a steep first-year discount, then renew you at a higher rate. The advertised number wins the comparison table; the renewal number is what actually leaves your account. The only defence is a written price-lock, or doing the year-two math before you commit — which is exactly what the rest of this post does.
What StockZip costs
StockZip publishes four flat tiers, and the price you sign up at is the price you renew at — stated in writing on the pricing page. Billed annually, the monthly-equivalent prices are straightforward.
Free — $0 forever, for 100 items and 1 user. Starter — $14.99/month billed annually ($179.88/year), for 2,000 items and 3 users. Pro — $45/month billed annually ($540/year), for 8,000 items and 8 users, and this is where the order workflow (sales orders, purchase orders, pick lists, deliveries, invoices) and the built-in Counter POS live. Ultra — $499/month billed annually ($5,988/year), for 100,000 items and unlimited users on fair use.
On monthly billing the same plans are $16.99 (Starter), $55 (Pro), and $598 (Ultra); the annual rate is the discount, and it does not expire after year one. There is no per-seat surcharge inside a tier and no separate charge for the order workflow — it is included on Pro.
What the other tools cost (as of July 2026)
Sortly (per sortly.com, as of July 2026) has a free plan, then Advanced at $49/month billed monthly or $24/month billed annually, and Ultra at $149/month billed monthly or $74/month billed annually. Those annual rates are the first-year promotional price — more on that in the next section.
Zoho Inventory (per zoho.com, as of July 2026) has a free plan capped at 50 orders per month, then Standard at $29/month, Premium at $79/month, Plus at $129/month, and Enterprise at $249/month, all billed annually. Zoho tiers by monthly order volume rather than by item count, and charges for extra users and warehouses above each plan’s built-in allowance — so the sticker price is a floor, not a ceiling, for a busy team.
inFlow (per inflowinventory.com, as of July 2026) starts higher: Entrepreneur at $129/month billed annually ($161 billed monthly), Small Business at $349/month annually ($436 monthly), and Mid-Size at $699/month annually ($874 monthly), with an Enterprise tier on custom pricing. inFlow is a heavier suite aimed at manufacturing and wholesale, which is why its entry price sits where other tools’ mid tiers do.
The renewal jump nobody quotes you
Here is the figure the comparison tables leave out. Sortly’s annual discount is 50% off the first year, then 20% off after that (per sortly.com’s published pricing, as of July 2026). So the $74/month you see on Ultra is a year-one rate: at the year-two 20%-off level, the same plan bills about $119/month, or roughly $1,430 a year — up from $888 in year one.
Play that out over three years on Sortly Ultra and you pay about $888 in year one and about $1,430 in each of years two and three, for a three-year total near $3,748. StockZip Pro — the comparable team tier — is $540 a year, locked, for a three-year total of $1,620. The advertised gap ($74 vs $45 a month) is small; the year-two gap is not.
Sortly’s Advanced tier follows the same curve: the $24/month first-year rate steps up to roughly $39/month (20% off the $49 list) once the intro year ends. None of this is hidden or dishonest on Sortly’s part — it is standard SaaS discounting — but you should price your second year, not your first, before you pick a tool.
What you will actually pay, by team size
Solo or a two-person shop under 100 items: $0. StockZip’s free tier covers it, and Sortly’s and Zoho’s free tiers are options too if their limits fit your workflow. Do not pay for software you have not outgrown yet.
A small team of three to eight tracking a few thousand items: this is the $15–$45/month band. StockZip Starter ($14.99/month annually, 2,000 items, 3 users) or Pro ($45/month annually, 8,000 items, 8 users) cover it without per-seat math; Zoho Standard ($29/month) or Sortly Advanced ($24/month year one, then more) are the comparable rivals.
A growing operation that needs orders, POs, and a POS: the honest floor is around $45–$130/month. StockZip Pro at $45/month includes the full order chain and Counter POS; inFlow’s comparable capability starts at $129/month, and Zoho’s order and warehouse features climb through Premium and Plus. Above this band you are buying enterprise volume, not more features.
The hidden-cost checklist
Before you sign, price these five line items, because they are where the advertised number and the real number diverge. One: extra users — is a warehouse crew included, or billed per seat? Two: order or transaction volume — Zoho and similar tools tier by orders per month, so a busy season can bump you a plan. Three: the renewal rate — is the discount permanent, or first-year only? Four: add-ons — extra warehouses, integrations, and API access are sometimes separate charges. Five: migration — importing your existing catalog should be a free CSV import, not a paid onboarding fee.
A plan that scores well on all five — a flat per-seat allowance, no order metering, a locked renewal rate, included add-ons, and free CSV import — will almost always cost less over three years than a cheaper-looking plan that fails two or three of them.
The bottom line
Most small businesses should budget $0 to $50 a month and grow into a plan, not pre-buy enterprise capacity. Start on a genuine free tier, move to a flat mid-tier when you need orders and a real user allowance, and read the renewal terms before the discount, not after.
StockZip built its pricing around exactly that: free for 100 items, flat paid tiers with users included, and a signup-equals-renewal price in writing. Whatever tool you choose, price your second year — that is the number that actually matters.
