SKU.io started as an internal tool. In 2008, our founder took over a family e-commerce business and went shopping for software that could run a real multi-channel operation — inventory, purchasing, channels, accounting, all of it. Everything on the market came up short the same ways: workflows that ignored how sellers actually work, accounting that never matched reality, interfaces from another decade, APIs that were an afterthought.
So we built our own. We ran the business on it for years before anyone else touched it. In 2019 it became a product, and it has been shaped every week since by the same test: does this work for an operator with real orders, real suppliers, and real money on the line — including ours, because we still run our own store on it.
What we believe
1. Inventory is a ledger, not a guess.
Every unit movement — receipt, transfer, fulfillment, adjustment — is an event in a perpetual, auditable ledger. When a number looks wrong, you don't re-sync and hope. You open the history and watch what happened. Trust isn't a feature; it's the architecture.
2. Profit is the point.
Revenue dashboards are decoration. Operators need the contribution margin of every order after landed cost, fees, and shipping — traceable to source documents, matching the accounting system. The books and the software should never tell two stories.
3. Software with a service.
We solve business problems; the license is just how it's packaged. When your operation has a workflow nobody supports, we build it — quoted plainly, shipped in days or weeks, folded into the product so the next customer benefits too. No enterprise services division, no change orders, no "scoped for 2030."
4. Speed is the moat.
Where we know no one will compete with us is speed of development and service. The features you ask for this month ship this month — read the release notes and check. A vendor's roadmap is a promise; a changelog is a record.
5. Talk to the people who build it.
Every demo, every onboarding, every escalation involves the people who write the code — usually the founder. That's not a scaling problem we haven't fixed yet; it's the product working as designed. Sellers don't need another account manager. They need answers.
6. Open by default.
The entire platform runs on a public, documented API — the same one our own frontend uses. Your data is yours to script, export, and automate. Connect an AI agent to your account and let it do the clicking. Lock-in is a business model; we'd rather be kept.
What we don't do
We don't charge onboarding fees. We don't hide pricing behind a sales process. We don't sell to sellers we can't help — if you're small and simple, we'll say so and point you somewhere cheaper. And we don't promise polish we don't have: the product moves fast, and occasionally you'll catch it mid-stride. What you get in exchange is a system that grows around your operation instead of forcing your operation into its shape.
