countX: countx.com's price page redirects to JTL, which lists Free 0 €, Core from 39 € and Professional from 139 € a month net; the OSS return costs 99 € a month extra.

What do the three providers say about OSS?

OSS means you report the VAT on your distance sales to private customers in other EU countries centrally to the Federal Central Tax Office instead of registering in each country; taking part is optional (§ 18j UStG). You need one of the two once you are established only in Germany and these distance sales (together with certain electronic services) exceed 10,000 € net in the previous or the current year, because VAT of the country of destination then applies (§ 3c(4) UStG, BZSt: One-Stop-Shop).

How do Taxdoo and hellotax differ?

Taxdoo combines transaction data from marketplaces and shops and has accountants book in DATEV ("GoBD-konform"). Plans scale with data sources, incoming invoices and expert hours.
hellotax lists OSS as its own plan. The page lists "Kostenlose OSS-Registrierung" (free OSS registration) and "Einreichung von OSS Meldungen durch unsere Steuerberater" (filing by its tax advisers), but under "Zusätzliche Kosten" (additional costs) also "OSS Registrierung für 149€ (einmalig)" (one-off). Official fees are not included per the page.

What this means for you: If you mainly want someone to file OSS, look at the hellotax plan first; if you want to bundle accounting, at the Taxdoo plans.

What about countX?

countx.de leads to a domain-sale page. The countx.com home page still shows countX ("© 2026 countX GmbH"); its price, imprint and OSS pages redirect to jtl-software.com. The JTL page "Umsatzsteuer-Compliance" says: "Mit der direkten Anbindung an JTL-Wawi laufen alle Transaktionen, Lagerländer und Fristen automatisch ins System, ganz ohne manuelle Aufbereitung." The JTL price page lists Free (0 €), Core (from 39 € a month) and Professional (from 139 € a month), "Alle Preise netto" (all prices net), and the OSS return at 99 € a month, "auf Wunsch direkt beim BZSt für dich eingereicht" (filed with the BZSt on request).

What this means for you: If you search for countX, prices and services lead you to JTL; ask there whether they file the OSS return for you and what it costs.
