About SKU.io
Built by a seller, for sellers
Kalvin Mizzi has been an e-commerce seller since 2008. When his multi-channel business outgrew every operations platform he evaluated — workflows that ignored how sellers actually work, accounting that never matched reality — he wrote his own: inventory, purchasing, sales channels, and accounting in one system, shaped by daily use in a real operation.
That internal ERP ran his business for a decade before it had a name. In 2019 he rebuilt it as sku.io so other sellers could run on it too.

Still an operator
Kalvin still runs his own store on sku.io today. That settles most product debates before they start: when a workflow is slow or a number is hard to trust, he feels it in his own operation first. The software is built around how a seller works — purchase orders that track landed cost, inventory that behaves like an auditable ledger, profit you can trace to source documents.

Every demo is with the founder
There is no sales team. When you book a demo, you get Kalvin, the product, and real data — and you can bring your hardest operational questions. If sku.io isn’t the right fit for your business, he’ll tell you that too.
