What does Taxdoo offer per its own site?

taxdoo.com states, among other things (Taxdoo: home, Taxdoo: e-commerce accounting, German):

Audience: "Für Onlinehändler" (for online sellers) who sell through marketplaces and shops such as Amazon, Shopify or eBay.
Data: "vereint deine Transaktionsdaten aus Marktplätzen, Shops, Payment- und ERP-Systemen" (combines your transaction data); "Schnittstellen zu Amazon, Shopify, Paypal etc. direkt angebunden" (interfaces connected directly).
Bookkeeping: "GoBD-konform"; "unsere Buchhalter prüfen und verbuchen das Ergebnis GoBD-konform in DATEV" (our accountants check and book the result in DATEV).
VAT: "Du tätigst die UstVA selbst aus der Software, ohne Umweg über Dritte" (you file the VAT return yourself from the software).
OSS and ZM: the page names "Daten für OSS-Meldung" and "Daten für ZM" (data for the OSS return and the recapitulative statement); it does not say who files them.
Tax advice: "durch auf E-Commerce spezialisierte Partnerkanzlei" (by a partner firm specialised in e-commerce).
Restriction: "Derzeit richten sich unsere Leistungen ausschließlich an Unternehmen mit Sitz in Deutschland" (currently only for companies based in Germany).

What this means for you: per its site, Taxdoo is accounting with advice; for the OSS filing, ask Taxdoo who transmits it.

What does Taxdoo cost in a price comparison?

Prices per the provider, retrieved 29 October 2026. Taxdoo calls them "Einstiegspreise" (entry prices) per month, "zzgl. der gesetzlichen Umsatzsteuer" (plus statutory VAT), all packages "monatlich kündbar" (cancellable monthly) (Taxdoo: prices, German):

Package	Price per month (Taxdoo plus VAT, VAT GPT incl. VAT)	Data sources	Incoming invoices	Expert hours	Amazon and OSS per the site
Taxdoo Basic Go	from EUR 49	5	50	0.5	VAT return included; Amazon CEE, OSS and ZM data bookable
Taxdoo Comfort Pro	from EUR 149	20	100	2	VAT return and Amazon CEE included; Amazon PAN-EU, OSS and ZM data bookable as add-ons
Taxdoo Premium Max	from EUR 399	40	250	5	VAT return, Amazon PAN-EU, OSS and ZM data included
VAT GPT Free	basic functions, free	–	–	–	process Amazon and eBay reports, calculate VAT for Germany and OSS (sending only with Pro)
VAT GPT Go	30 days free	–	–	–	all Pro functions
VAT GPT Pro	EUR 49 per month or EUR 444 per year, incl. VAT	–	–	–	send VAT return and OSS

Taxdoo also lists charges for expert hours above the quota, the comfort service and annual accounts by the partner firm. A dash ("–") means: not stated explicitly.

What this means for you: the packages are entry prices; compare the price with the extras you actually need.

For whom does Taxdoo fit, and for whom the alternative?

Taxdoo fits if you want bookkeeping, accountants and tax advice from one provider and combine several sales channels in one set of books.

VAT GPT fits if you want to check the tax figures yourself. If you are established only in Germany and your distance sales to private customers in other EU countries (together with certain electronic services) exceed EUR 10,000 net in the previous or the current year, VAT is due in the country of destination (§ 3c(4) UStG, German). Instead of registering in each country, you can then join the OSS scheme and file one OSS return with the BZSt (§ 18j UStG, BZSt: One-Stop-Shop, German); VAT GPT calculates it from your reports:

Import Amazon and eBay reports as CSV and split VAT for Germany and the EU (OSS).
Create the VAT return, OSS return, EÜR, trade tax and income tax.
With Pro, send via ELSTER, and the OSS return to the Federal Central Tax Office (BZSt).

What this means for you: if you prefer to confirm the figures yourself, you need less advice in the package.

How do I work with VAT GPT?

The method: Upload – check – send.

Upload: Amazon or eBay reports and invoices; the AI reads amounts, countries and tax rates.
Check: you review and confirm the values.
Send: with Pro via ELSTER to the tax office, the OSS return to the BZSt.

VAT GPT is not tax advice. Try it free

What this means for you: the Go plan (30 days with all Pro functions) shows on your own data whether the reports come in cleanly.
