Cross-border VAT, matched to exactly where you are

Four services, each built for a different situation. Here's exactly which one fits you, what's included, and what it costs.

How I'm built to help you

My role is to be your independent check — vetting, verifying, and correcting your cross-border VAT, kept separate from whoever registers you. Keeping those two roles apart is what lets me tell you the truth about a filing or an intermediary without any conflict of interest. In practice: I'm not a registered IOSS intermediary myself, so if you need one, I help you choose and monitor a reliable one rather than register you and mark my own homework. Here's exactly how that plays out, depending on your situation.

Which situation are you in?

Not sure? Run the free 60-second diagnostic first — it'll point you to the right one.

For businesses established in the Netherlands/EU

OSS/IOSS Filing Prep

Selling cross-border within the EU? I calculate your OSS/IOSS VAT and prepare the return. You review, approve, and file — or authorize me to file it on your behalf, the same way I handle your regular VAT.

Calculation every filing period
Return prepared, ready to file
Filed by you, or by me on your authorization
Folded into your monthly bookkeeping
From €65/month
For anyone already registered (OSS or IOSS)

Filing Verification & Reconciliation

Being registered doesn't guarantee every filing is accurate. I reconcile your actual sales against your declared filings every month — not just once a quarter — so a mismatch gets caught while it's a five-minute fix, not a corrected return.

Monthly reconciliation: actual sales vs. declared VAT
Discrepancies flagged the same month, not the next quarter
Applies whether you're EU or non-EU established
Works alongside any registration you already hold
From €95/month
For non-EU businesses selling physical goods into the EU

IOSS Intermediary Verification & Reconciliation

IOSS legally requires you to appoint your own EU-based intermediary — I'm not one, and I won't pretend to be. What I do instead: vet the intermediary you choose (or help you pick one), manage the transition if you're switching, and reconcile your actual sales against what they declare every month.

Intermediary due diligence and selection
Transition management if you're switching providers
Monthly reconciliation of your intermediary's filings
Early warning if their registration health changes
From €120/month
For businesses registered under the wrong scheme

Registration Correction & Ongoing Verification

A scheme mismatch — like being registered for IOSS while only selling digital products — usually means whoever set it up didn't check what you actually sell. I help you get registered correctly, then verify your filings every month afterward.

Diagnosis of what went wrong and why
Direct correction if no intermediary is legally required
Coordinated intermediary correction if physical goods are involved
Ongoing monthly verification afterward
€150 one-time correction + from €95/month ongoing

Common questions

Why aren't you a registered IOSS intermediary?

IOSS intermediaries carry joint and several liability for their clients' VAT — legally, the intermediary can be held responsible if a client underreports or misfiles. I decided early on not to take on that liability, because the same party registering you and checking the work has an incentive to look the other way. Instead, I focus on being the independent check.

What's the difference between OSS and IOSS?

OSS (One Stop Shop) covers intra-EU B2C sales — goods already in the EU, or digital services — for EU-established businesses (or non-EU businesses via the separate Non-Union scheme). IOSS (Import One Stop Shop) covers imported physical goods under €150 sold to EU consumers from outside the EU. They're not interchangeable, and using the wrong one is a common — and costly — mistake.

I'm a non-EU business selling only digital products. Do I need an intermediary?

No. Non-Union OSS, which applies to your situation, doesn't require an intermediary — you can register directly. If you've been told otherwise, or if you're currently registered for IOSS instead (which only covers physical goods), that's worth a closer look.

Can you recommend an IOSS intermediary?

I can help you evaluate and choose one as part of the Intermediary Verification & Reconciliation service. I don't operate as one myself, but I'll help you pick a reliable one and keep checking their work afterward.

Not sure which one fits?

Tell me a bit about your situation — I'll point you to the right service, or tell you honestly if you don't need one yet.
