Result

Amainvoice fits pure Amazon sellers with PAN-EU stock who need exactly that depth. KudTax fits as soon as a second channel appears – or if you prefer importing Amazon documents into KudTax and reconciling everything together: KudTax is Amazon Selling Partner software itself and has an Amainvoice integration.

KudTax does not necessarily replace Amainvoice: Amainvoice is also available as an integration inside KudTax. To the Amainvoice integration

Pricing compared

Net monthly prices at three typical volumes. Where a provider does not bill by orders, the derivation is given below – and the table says “not stated” instead of guessing.

Orders / monthKudTaxAmainvoice
100€19€43
500€49€120
1,000€99€153
€ / month · Net/gross not stated on the provider's page
KudTax
KudTax: €0 up to 25, €19 up to 100, €49 up to 500, €99 up to 1,000, €129 up to 2,000, €149 up to 3,000 orders a month; above that Enterprise on request. Every feature in every tier, plus VAT.
Amainvoice
Prices from 09 Feb 2026: up to 200 documents flat €43; 201–1,000 documents €0.24 each, max €153; 1,001–2,500 documents €0.16 each, max €279. One document per order assumed here. Whether prices are net or gross is not stated on the pricing page.
What the price does not include
  • Per-document billing above 200 documents (€0.04–0.24); Vendor accounts €490–1,690/month.
  • Per the English T&Cs, fees are due three months in advance.

What Amainvoice does well

  • Very deep in Amazon: payout breakdown, stock movements between EU countries, PAN-EU/CEE logic and Vendor accounts.

  • OSS filing and multi-country VAT are core features, not add-ons.

  • 14-day free trial without a credit card, ends automatically.

Where Amainvoice hits its limits

  • Amazon only. Shopify, eBay, Kaufland, PayPal or Stripe have to be booked elsewhere.

  • Billed per document: around €120 at 500 orders versus €49 at KudTax.

  • No e-invoicing (XRechnung/ZUGFeRD), no AI features.

  • Net/gross and minimum term are not stated on the pricing page.

Booking-ready for your target system

Export to DATEV, Lexware, sevDesk, BMD, SAP and more – as a posting batch with tax keys and document links, GoBD-aligned.

Start for nothing

Free for good up to 25 orders a month, no payment details. Tax advisors work directly in the account, per client.
