Top 10 inventory programs with a free plan, trial or one-time payment

Top 10 inventory programs with a free plan, trial or one-time payment

Getting inventory under control should not mean signing up for a blind subscription. In small retail businesses, the cost of entry matters as much as the features: if the program does not work out, what you lose is not only money but also the time spent loading products and recording movements. That is why many people look for inventory programs with a free plan, a trial or a one-time payment: ways to validate the software before committing to a monthly expense. This list brings together ten options that currently offer one of those three entry points.

Before we continue, the usual transparency note: this article belongs to the blog of Kardex Tauro, and Kardex Tauro appears in the list. We say this openly so it is clear that this is not a comparison written from the outside, but a guide prepared by a market participant. Plan and price data come from each provider's public pages, as of approximately September 2026, and can change. Nothing below is a purchase recommendation: it is material for comparing with your own situation.

How this list was built

The selection started from a single, verifiable criterion: the program must let you start without paying for a full subscription right away, either through a stated free plan, a time-limited trial or a one-time license. Two more filters were added: the software must suit small retail businesses, and it must publish its entry conditions. Several well-known providers do not publish prices and were left out precisely for that reason.

• Stated free plan: the provider publicly announces a no-cost version, usually with limits on items, users or documents.
• Time-limited trial: full access for a set number of days (for example, 15 or 30) and then a paid subscription.
• One-time payment: you buy the license once and there is no mandatory monthly fee; there may be a separate charge for maintenance or updates.

The ten programs are ordered alphabetically, not by merit: there are no positions, no winner and the order expresses no preference. The table in the next section summarizes the objective data, and the comments about each program stick to what the provider itself states.

Entry-cost comparison

The table sums up the essentials: type of deployment, cost to get started according to what was published around September 2026, and the profile each program targets. The figures are those stated by each provider on its site; use them as a starting point and confirm them before deciding.

The ten programs, in alphabetical order

A quick read, from A to Z, with a short description based only on the information in the table:

• Alegra: cloud suite for SMEs and accountants in Latin America; it states a free plan for inventory and invoicing in Colombia, while the rest of its catalog is paid by subscription.
• Aspel SAE: desktop program for purchase-sale administration with kardex, aimed at SMEs in Mexico; it is sold as a one-time license plus maintenance, and demos are arranged through a distributor.
• CONTPAQi Comercial: desktop ecosystem with cloud options, with inventory (kardex), sales and invoicing modules for SMEs in Mexico; it is contracted per product by subscription, with demos through a distributor.
• Kardex Tauro: kardex and inventory software with invoicing for retail SMEs in Latin America; it runs on Windows desktop over local SQLite, with an optional server mode; a free plan is available and the full version is paid per year and per device.
• kardex.lat: desktop option with cloud sync for micro businesses in Spanish; you pay once (approx. USD 49.99-99.99) with no monthly fee, and its stated focus is simplicity.
• Katana: cloud software for small manufacturers; the material is in English; it states a free plan and paid plans from approx. USD 299 per month.
• Nubox: cloud platform for electronic invoicing and administration for SMEs in Chile, Peru, Mexico and Colombia; it is contracted through a monthly subscription, and trials are checked with the provider.
• Odoo: global suite with inventory, sales and point of sale; since it is open source you can install it yourself at no cost, and the SaaS subscription is optional.
• Scrampi: cloud point of sale with offline mode for shops, pharmacies and restaurants in Colombia; it states a 30-day trial and then a subscription of approx. COP 46,000 per month.
• Zoho Inventory: cloud inventory with ecommerce integrations and global reach; it states a free plan with limits and paid plans in USD.

Free plan, trial or one-time payment: what to consider

The three entry points look similar, but each one changes what you pay over one and three years, and what you risk if the program does not work out. Before choosing, it is worth answering these questions:

• What limits does the free plan have?: there is almost always a cap on items, users or documents per month. What matters is whether the limit covers your real operation and what happens when you exceed it: does it block you or push you toward a paid plan? A free plan that covers your current volume can honestly stay free for years; one that runs out two months in is just a long demo.
• Does the trial ask for a card?: some trials require payment details and roll into a subscription if you do not cancel them. If you want no surprises, check whether automatic renewal exists and note the date. A poorly managed 30-day trial can cost a full month (or more).
• How much will you pay in total over three years?: a monthly subscription looks small until you multiply it: about USD 30 per month is around USD 360 per year and more than USD 1,000 over three years, before taxes. A one-time payment is paid once (sometimes with separate annual maintenance), and a free plan costs zero while it covers you. Compare the accumulated cost, not the first-month fee.
• Are your data still yours?: it is worth knowing whether you can export products, movements and history, and in which format, and what happens if you stop paying: is the information locked, available for download or deleted? In a local desktop program your data live on your machine; in the cloud they live on the provider's servers, so the exit question matters twice as much.

In short: a free plan is ideal for starting and validating, a trial helps you evaluate the full features with an expiry date, and a one-time payment makes sense when you already know the program does the job and you prefer not to carry a monthly fee. None of the three replaces testing with your own products and movements.

Kardex Tauro in this list

We included Kardex Tauro because it meets this list's entry criterion: it has a free plan available, and the full version is paid per year and per device, with no per-user monthly fee and no mandatory subscription. It runs on Windows over a local SQLite database, with an optional server mode if you need to work on a network, and it is aimed at kardex and inventory management with invoicing for retail SMEs in Latin America. If it interests you, the honest path is to start with the free plan, load your products and test real movements before deciding whether the yearly payment is justified.

Final note: the plans and prices summarized here correspond roughly to September 2026 and can change without notice; each provider adjusts its terms whenever it considers it necessary. Before signing up, check the current terms on the official site of the program you are interested in.
