Is there any free inventory software that can handle a 2,000-SKU store?

I run a small home goods and hardware store in Madrid. Right now, we actively have around 2,100 SKUs on our shelves and in storage. Up until now we tried tracking everything manually via spreadsheets, but as the business grew our physical register sales and the spreadsheet counts stopped matching up. btw when we did inventory last month we found a stock discrepancy of about 1,400 Euro; some items are sold out but show as in stock, while others are sitting on the shelf with zero record.

Switching to a system that integrates with a barcode scanner and updates in real time across the two shop computers has become an absolute necessity. When I search online, tons of free inventory tools pop up but most have a 100 or 500-item limit, or they cripple the barcode support. I don't want to commit to a 50-80 Euro monthly software subscription right off the bat.

Is there really a free or open-source solution that can smoothly handle 2,000 SKUs or should we just bite the bullet and go for paid software? What should I watch out for when migrating our data?

Short answer: When you have over two thousand SKUs and multiple terminals, relying on entirely free cloud tools is practically impossible; free tiers are almost always capped at 100-300 items or limited to a single user. For a permanent fix, you either take on hosting costs and self-host open-source inventory software, or jump straight into an entry-level commercial tier.

The biggest trap with free cloud tools comes up during data migration. You can easily import 2,000 SKUs as a CSV, but when you need to export data, take real-time backups, or print formatted barcode labels, they force you behind a paywall. Installing open-source software locally might seem tempting at first, but database deadlocks, data corruption from power outages, and maintaining security patches will end up costing you far more than a monthly subscription.

Here is how I'd approach the migration: First, clean up your existing spreadsheet. Ensure every product has clean columns for unique barcode, item name, category, shelf location, cost price, VAT rate, and reorder threshold. If you aren't tech-savvy, don't waste time deploying self-hosted stacks. Choosing a turnkey cloud solution that complies with local Spanish tax regulations, supports local invoicing, and starts around 25-40 Euro a month will pay for itself in a single month by eliminating that 1,400 Euro shortage.

Don't jump straight into importing your spreadsheet data. Clean up duplicate barcodes and trailing spaces first. Instead of wasting time hunting for free tools, use free trials on standard commercial apps to test how smoothly they import your CSV. Do a test run of actual sales with just 20 items before uploading everything.

Free software usually takes you hostage the moment your shop grows. You enter 2,000 items and by month four you hit a paywall just to see barcode history or add a second user. The 40 hours of work you'll spend setting up and troubleshooting a free tool is worth way more than a year's software subscription.

We went through a similar process in Valencia with 1,800 SKUs. We tried a free open-source system, and when two terminals on the local network sold the same item at the same time, the stock went negative. In the end, we switched to a cloud-based system that costs us 35 Euro a month; our stocktaking time dropped from 6 hours a week to just 1 hour.

To avoid a massive headache during data migration, stick to these three rules: 1) Define product variants as separate rows and codes. 2) Enter critical stock levels from day one so the system can generate purchase orders automatically. 3) Link VAT rates directly to the product card instead of entering them manually at checkout.

Since you will be running simultaneous transactions from two separate checkouts, simple file-based free desktop software will crash. You need at least an architecture running on a relational database that handles transaction-level locking. Cloud-based solutions manage data consistency centrally, making them far more stable for a brick-and-mortar store.

When I opened my first shop, I installed some community software I found online just to keep costs at zero. Right in the middle of our summer rush hour, the system froze and the checkout line spilled out onto the street. We couldn't print receipts, and customers just dumped their items on the counter and walked out. That was the day I realized inventory software is the last thing you should ever cheap out on.

we started with spreadsheets too then everything turned into a mess. btw if u have two checkouts forget about free stuff imo. 30 euro a month is nothing for an operating expense, totally worth the peace of mind at the register.

I've been dealing with this for a long time. Processes without records never improve, because you don't know what to fix.

my question might sound amateurish, sorry about that. btw if you don't write this down from the start, it leads to arguments later.

if you have questions, write them; I'll answer as best I can.

I can't fully agree with this. Don't hesitate to ask; those who don't ask always pay more.

I've been dealing with this for a long time. Hasty decisions become decisions you have to fix six months later.

There's also a measurement aspect to this. Trying to do this alone is the most expensive way.

If you post the result here, it will help others too.

My perspective changed after experiencing that. When making decisions, write down the worst-case scenario too not just the best.

I'm also curious if anyone does it differently.

Thanks, that was the answer I was looking for. The cheapest quote is usually the least thought-out one.

I have an objection here. The harder it is to reverse a decision, the slower you should make it.

This is my opinion, I'm not claiming it's absolute truth.

The discussion got scattered, let me summarize. If scope grows, either time or budget must grow. There is no third option.

If I were you, I'd go this route.
