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.

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.
AccountOne
'It starts at €24 for small merchants. From 15,000 transactions we cap the base price at €129 and charge only €10 per further 1,000 transactions.' A transaction is a sale, refund, payment or transfer; on average 2.2 transactions per order according to the provider. Intermediate steps are only shown in the calculator, so no per-order figures here.
What the price does not include
  • From 15,000 transactions €129/month plus €10 per additional 1,000.
  • Training €990 per module; customisation and consulting €140/hour.

What AccountOne does well

  • Over 40 connections including Temu, Zalando and Decathlon; export also to BMD, SAP and Navision.

  • Integrated VAT compliance through tax.fish and a tax matrix for OSS.

  • Unlimited users and free multi-client access for tax advisors in every plan.

Where AccountOne hits its limits

  • Billed per transaction, not per order – at 2.2 transactions per order the calculator is the only way to the real price.

  • No e-invoicing and no AI features per the website.

  • Customisation costs €140/hour, consulting modules €990.

  • Minimum term is not stated.

What KudTax does differently

One plan, every feature

No module kit: marketplaces, payment providers, OSS reporting, e-invoicing and AI matching are included in every tier. The price depends on order volume alone.

Every channel in one reconciliation

60+ marketplaces, shops, payment providers and invoicing tools come together in one cockpit – payouts, fees and refunds are matched against documents.

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.
