An independent software studio

Baltano is a one-person software studio based in Poland. We build desktop and web applications — and we are now bringing that work to online stores on WooCommerce and Shoper.

Where we are heading

Our first product for the WooCommerce ecosystem is Merchlint, published in the WordPress plugin directory in September 2026 and free to install. It addresses a narrow problem: stores accumulate bad data. Products without images, prices that never got updated, variations nobody can buy, categories that lead nowhere. None of it breaks the store outright, so none of it gets noticed — it just quietly costs the owner orders.

Merchlint finds those problems and reports them. It does not silently repair anything. Every change to a live store stays a decision made by the person who owns it.

The second is Merchgain, a profit and margin report. WooCommerce tells a shop owner what they sold; since version 10.3 it also stores what each item cost, but it still does not say what was earned. Merchgain reads that native cost field and answers the question the sales report cannot. It is now in the plugin directory as well, and free to install.

Since October 2026 Merchlint also works on Shoper, the Polish store platform, as an app in the Shoper App Store. The Duplicate SKU and GTIN Finder, a small free plugin, takes three of Merchlint’s checks and runs them on their own. All of them read and report, and none of them writes to your store.

How we build

Read-only by default. A tool that inspects a system has no business writing to it. Bulk auto-fixes are how plugins destroy catalogues.
No invented findings. A report that cries wolf is worse than no report. We would rather miss an edge case than flag a healthy product as broken.
A missing number is not a zero. Where data is absent we say so, rather than substituting a value that makes the report look complete.
It has to survive a real catalogue. Everything we ship is tested against stores with tens of thousands of products, not against a demo shop with twelve.
Plain about limits. Our reports say what was scanned, what was skipped, and why.

Merchlint for WooCommerce

A data quality auditor for WooCommerce catalogues. It scans products, variations, prices, media and categories, then reports what it found and what it is likely costing you. It never modifies your store.

Duplicate SKU and GTIN Finder

Three checks from Merchlint in a small plugin of their own: products sharing an SKU, products with no GTIN, UPC, EAN or ISBN, and products sharing one. It never writes to your catalogue.
