Taxdoo alternative Poland VAT: Case Study for a German Amazon Seller

When Taxdoo announced changes to its service offering, many sellers suddenly had to rethink how they handle cross-border VAT. This case study shows how one German Amazon FBA seller switched to a Taxdoo alternative Poland VAT solution with hellotax – and at the same time built a Taxdoo alternative Czech Republic VAT setup that keeps their OSS reporting and proforma invoices running smoothly.

The client asked to stay anonymous, but the situation will sound familiar if you are using Amazon FBA with stock in Poland and Czechia and are now looking for a practical Taxdoo replacement.

1. Background: German Amazon FBA seller expanding via PL and CZ

Our client is a German business selling physical products on Amazon FBA.

• Home country: Germany

• Sales channel: Amazon FBA (EU)

• Annual turnover in EU + UK: between €100,000 and €1,000,000

• Warehouse setup: goods stored in Germany and at least one additional EU country

For several years, the seller used Taxdoo for:

• VAT compliance in Poland (PL) and Czech Republic (CZ)

• OSS analysis and export files

• Proforma invoice handling

As long as everything stayed stable, this “all-in-one” approach worked reasonably well. But once Taxdoo’s strategy shifted and the seller started hearing about service changes and slower response times, they began to look for a Taxdoo alternative Poland VAT solution that would be more focused on VAT itself instead of broad accounting features.

At the same time, they wanted a Taxdoo alternative Czech Republic VAT setup that could take over seamlessly from Taxdoo without creating gaps in Polish and Czech VAT filings.

2. The challenge: Switching from Taxdoo without missing deadlines

The seller’s situation was quite typical:

• They were already VAT-registered in Poland and Czech Republic.

• Taxdoo handled PL and CZ VAT returns, EC Sales Lists and related filings.

• Taxdoo also provided OSS analysis and proforma invoices.

They now wanted:

• A specialised VAT provider (hellotax) to take over PL and CZ VAT compliance.

• Continued OSS analysis so their existing accountant could keep filing OSS.

• Ongoing proforma service for their Amazon operations.

• A clear answer on timing and PoA transfer, so they could safely cancel their Taxdoo contract.

Their main concerns were:

1. Risk of gaps in reporting
   Taxdoo warned that changing the Power of Attorney (PoA) too close to a filing deadline could cause delays and problems with local tax offices.

2. Timing of the takeover
   The seller wanted to terminate Taxdoo at the end of January and let hellotax handle VAT from the February period onward – but needed to know if that was realistically possible.

3. Avoiding double work
   They did not want one provider partially filing for a month and the other finishing it. They wanted a clean switch and clear responsibilities.

In short, they needed a Taxdoo alternative Poland VAT and Taxdoo alternative Czech Republic VAT solution that would:

• Take over the existing PL and CZ VAT numbers.

• Handle all local returns in both countries.

• Provide OSS exports and proformas.

• Manage the PoA transition in time for the 02/2026 reporting period.

f you want to see the official rules yourself, you can also check the government pages. The Polish biznes.gov.pl portal explains when foreign businesses must register and file VAT in Poland. The Czech tax office website does the same for VAT in Czechia. These official pages confirm the same VAT duties that hellotax takes over for you in Poland and Czech Republic.

3. Why the seller chose hellotax as a Taxdoo alternative

After comparing several tools and agencies, the seller decided to move forward with hellotax for a few key reasons.

3.1 VAT-first, not accounting-first

The seller didn’t want another “all-in-one” accounting system. They needed a Taxdoo alternative Poland VAT provider that:

• Focuses on VAT registrations and filings.

• Understands Amazon FBA flows and cross-border stock movements.

• Can plug into their existing accounting setup instead of replacing it.

hellotax matched that approach: a VAT engine with marketplace integrations, not a full bookkeeping suite.

3.2 Experience with Taxdoo takeovers

This was not hellotax’s first migration from Taxdoo. The sales and onboarding team could explain:

• How PoA transfers are handled in Poland and Czech Republic.

• How to coordinate the last Taxdoo period and the first hellotax period.

• Which documents and data would be needed, and by when.

This gave the seller confidence that their Taxdoo alternative Czech Republic VAT and Poland VAT setup would be up and running in time.

3.3 Transparent pricing with yearly discount and free months

The client chose the yearly plan for PL and CZ, which included:

• No registration/takeover fee in the yearly plan (PL & CZ).

• Monthly equivalent of €99 per country (paid yearly in advance).

• OSS export file at a reduced monthly price.

• Proforma service at a reduced monthly price.

• Two extra months free added to the yearly term for all booked services.

That meant: 14 months of service for the price of 12, which made the switch financially attractive as well.

4. The solution: A clean Taxdoo alternative Poland VAT and CZ setup

hellotax designed a solution that covered all the moving parts:

4.1 Countries and services included

Countries handled by hellotax in this case:

• Poland (PL):

  • Takeover of existing VAT number

  • Ongoing VAT returns and related reports

• Czech Republic (CZ):

  • Takeover of existing VAT number

  • Ongoing VAT returns and related reports

Core services:

• VAT number takeover in PL and CZ

• Monthly/quarterly VAT returns in both countries

• Reporting of intra-Community supplies / movements (where needed)

• OSS export file each period

• Proforma invoice service

• Tax Letter Inbox for PL and CZ

This framework acts as a Taxdoo alternative Poland VAT and Taxdoo alternative Czech Republic VAT solution tailored specifically to Amazon FBA sellers with warehouses in both countries.

4.2 OSS export and accounting workflow

The seller’s German accountant remained responsible for:

• German VAT

• OSS filings

hellotax’s role:

• Pull transaction data from Amazon FBA.

• Prepare a structured OSS export file.

• Make that file available in the hellotax account.

The accountant can then:

• Import the OSS export.

• Use it for OSS returns without logging into Amazon or building complex spreadsheets.

This way, the OSS process stays under the accountant’s control, while hellotax does the heavy lifting with the marketplace data.

4.3 Proforma service

The seller also relied on proforma invoices for logistics and customer communication.

With hellotax:

• Proforma invoices for their Amazon setup are generated as part of the service.

• In the yearly plan, the proforma service is billed at a reduced monthly price and extended by two free months, just like VAT and OSS services.

This means the seller doesn’t need a separate tool just for proformas – it’s integrated into their Taxdoo alternative Poland VAT and Czech VAT solution.

5. Implementation: From Taxdoo cancellation to hellotax go-live

5.1 Answering the critical question: “Is it safe to cancel now?”

Taxdoo’s reply to the seller included a warning: PoA changes can take time, and a rushed switch could lead to late filings and problems with tax authorities.

The seller asked hellotax very directly:

“Can I safely cancel Taxdoo as of 31.01.2026 and let you handle VAT from 02/2026, or is this too tight?”

hellotax’s answer was:

• Takeover of VAT compliance in Poland and Czech Republic typically takes 4–6 weeks.

• If the client starts promptly, there is enough time to:

  • Have new PoAs in place.

  • Ensure hellotax can file 02/2026 VAT returns on time (due by 25 March 2026 in many cases).

Based on this, hellotax confirmed that the schedule was realistic and that the seller could safely keep the Taxdoo cancellation at 31.01.2026.

This clear timing reassurance was a key factor in the decision to proceed.

5.2 Order confirmation and onboarding

Next steps:

1. The seller confirmed they wanted the yearly plan for PL and CZ, including OSS export and proforma service.

2. hellotax sent a personal order link by email.

3. The seller:

   • Completed the checkout.

   • Entered company details.

   • Accepted the terms with yearly payment.

4. The case was passed to the Account Management and local VAT teams for Poland and Czech Republic.

The onboarding process included:

• A checklist of documents needed for PL and CZ.

• Information on expected timelines for PoA and access to local tax portals.

• Instructions on how to connect Amazon so that sales data flows automatically.

5.3 Data integration and first filings

Once Amazon was connected, hellotax:

• Imported transaction data for PL and CZ.

• Classified sales and movements according to local rules.

• Prepared draft PL and CZ VAT returns based on the new responsibility split (Taxdoo until 01/2026, hellotax from 02/2026 onward).

• Generated the first OSS export file to be shared with the seller’s accountant.

After a short initial review, the returns and OSS exports were finalised and submitted/handed over within the agreed timelines.

6. Results: A stable Taxdoo alternative for Poland and Czech VAT

After the migration, the seller achieved several concrete results.

6.1 Safe transition without reporting gaps

Thanks to a planned timeline:

• Taxdoo handled all reporting up to 01/2026.

• hellotax took over PL and CZ from 02/2026 onward.

• PoA transfers were completed in time to avoid any late filings.

There were no missing months or countries in the chain – a key success factor for any Taxdoo alternative Poland VAT and Czech VAT migration.

6.2 Clear division of responsibilities

The new setup looks like this:

• Seller’s accountant: German VAT and OSS filing.

• hellotax: PL and CZ VAT compliance, OSS exports and proforma service.

This separation keeps the seller’s German accounting workflows intact, while hellotax focuses on the specialised cross-border VAT work in Poland and Czechia.

6.3 Less manual work and more predictability

Previously, the seller depended heavily on Taxdoo’s combined VAT + accounting style setup. After the change:

• VAT and OSS data comes from hellotax, optimised for cross-border compliance.

• Accounting and financial statements remain in the tools preferred by their German accountant.

• Proforma invoices, OSS exports and local VAT obligations in PL and CZ are no longer a stress factor.

The seller now has a modular setup: a Taxdoo alternative Poland VAT and Czech VAT layer that can evolve independently of their accounting system.

If you’re also planning to move away from Taxdoo and need a reliable partner for VAT in Poland and Czech Republic, now is the right moment to review your setup.

7. Lessons for sellers looking for a Taxdoo alternative in PL and CZ

This case highlights a few key points for other Amazon FBA sellers:

1. Plan your PoA change early
   Don’t wait until a few days before a deadline. Even with a 4–6 week takeover window, the sooner you start, the more buffer you have.

2. Separate VAT from accounting if needed
   You don’t have to replace your entire accounting solution. Many sellers choose a Taxdoo alternative Czech Republic VAT and Poland VAT provider like hellotax and keep their existing accountant and software.

3. Use VAT specialists for multi-country setups
   Local rules in Poland and Czechia can be tricky, especially with FBA stock movements. A dedicated VAT team lowers the risk of errors and fines.

4. Check what you actually need from your provider
   If VAT registrations, filings, OSS exports and proforma invoices are your main pain points, a VAT-first solution will probably serve you better than a big, general “platform” that tries to cover everything.

8. Is this Taxdoo alternative setup right for you?

A similar solution might be a good fit if:

• You are a German Amazon seller with stock in Poland and Czech Republic.

• You currently use, or used to use, Taxdoo for PL and CZ VAT.

• You want a Taxdoo alternative Poland VAT and Czech VAT provider that focuses on VAT rather than full accounting.

• You’d like to keep your own accountant in charge of German VAT and OSS.

hellotax can take over your existing VAT numbers in Poland and Czechia, manage local returns, provide OSS exports and handle proformas – while your accountant stays in control of your German books.

When you compare a Taxdoo alternative Poland VAT setup, it’s not only about registrations and filings in Poland and Czech Republic – you also need to think about how your VAT data flows into your German accounting. If you (or your Steuerberater) work with DATEV, it’s worth looking at how hellotax can replace Taxdoo on the VAT side while still delivering clean DATEV files. For a deeper, accounting-focused view of this, you can read our dedicated guide on Taxdoo alternative for DATEV VAT exports, which explains how to keep your DATEV processes stable while switching VAT provider.
