About Kelstad

Compliance software that feels settled.

Kelstad builds compliance software for Shopify merchants — starting with EU e-invoicing: whether the mandates apply to you, by when, and what to do about them. It's a new product, and we say so plainly. Everything on this site traces back to its official government source, so you can verify it yourself.

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 being built to handle it per order, inside the checkout you already use. Belgium's mandate is already in force — since January 2026 — which is why it's our first market; it applies to every B2B invoice from here on, not a single deadline, so we're building for the long run: targeting a Q4 2026 launch, with Germany and France following on their own mandate timelines.

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 Plain answers while the mandates roll out — each guide dated with when it was last reviewed, and nothing built to rush you. Compliance is stressful enough without a vendor adding to it.
EU-held Your data is stored in the EU. Compliance is included, never billed as a per-invoice surcharge.

Why we're building this

I started Kelstad because the official guidance on these mandates is scattered across government PDFs in three languages, and most Shopify merchants are left guessing whether they're even affected — let alone what to do about it. The rules are already landing: Belgium is live now, with Germany and France phasing in on their own schedules.

So I set one rule for the site: nothing is published without a link to the official source it comes from — Belgium's Peppol BIS, Germany's XRechnung and ZUGFeRD, France's Factur-X via an approved platform, each written up in plain language. If we can't cite it, we don't publish it. The app itself is being built to turn each Shopify order into a compliant invoice — in the required format, sent the way each country's mandate requires.

Kelstad is founder-run. I'd rather earn your trust with precision than borrow it with claims I can't back — so my name is on the Impressum, and when you write in, you reach me.

If that's the kind of vendor you want on this, you can join as a founding member now — it's free, it locks the founding price, and we'll tell you the moment it's live.
