About Kelstad

Compliance software that feels settled.


Kelstad builds compliance software for Shopify merchants — starting with EU e-invoicing. The kind of tool that should feel made by a firm that has done this for years, not a startup experimenting with your tax compliance.

What we're building

We're starting with the mandates in Belgium, Germany, and France that turn a simple invoice into a structured, transmitted document. Our first product is a Shopify app that handles it per order — inside the checkout you already use, across every country you sell to.

Exact Every mandate fact is cited to its official government source. Dates, thresholds, and standards named precisely — getting the details right is the product.
Settled Built to feel like it came from a firm that has done this for years: calm, plain-spoken, no hype and no scare tactics.
EU-held Your data is stored in the EU. Compliance is included, never billed as a per-invoice surcharge.
