Terms & Conditions (AGB)
Last updated: 2026-07-22
1. Scope
These Terms & Conditions (Allgemeine Geschäftsbedingungen) govern every engagement between you and Ilja Bytschok-Edler von Hoessle, sole proprietor, c/o POSTFLEX PFX-230-074, Emsdettener Straße 10, 48268 Greven, Germany ("I", "me"; see the Imprint). A "consumer" is a person acting outside their trade or profession (§ 13 BGB); a "business" is anyone else (§ 14 BGB). Clauses marked as applying to consumers or to businesses apply only to that group; everything else applies to both.
2. How a contract is formed
You send an enquiry by form or email; we discuss your situation; I send you an individual, fixed quote. The contract takes effect when you accept that quote by email or in writing. There is no order or payment button on this website. These Terms apply to the contract as referenced in the quote.
3. What I do — and what I do not
I reconcile the trading and on-chain data you provide and prepare written documentation of the figures, with methodology and an audit trail, using the accounting method you choose.
This is not tax advice (Steuerberatung). I am not a tax advisor, accountant, or lawyer. I do not determine your taxable result, prepare or file your tax return, or represent you before the tax authority. You — or your tax advisor — use my documentation to determine the taxable result and to file. You remain responsible for your filings.
4. Your cooperation
You provide the data needed for the work completely and accurately, and you confirm that it is your own or that you are authorised to share it. I may rely on the data you provide and am not obliged to audit it for completeness.
5. Prices and payment
The fee is agreed individually in the quote and stated in Euros. As a small business within the meaning of § 19 UStG, I do not charge value-added tax, and invoices are issued without VAT.
Unless otherwise agreed, 50% of the fee is due when the contract is concluded and the remaining 50% on delivery of the documentation. I issue an invoice for each instalment; payment is made by bank transfer to the account shown on the invoice, or by the payment link provided, within 14 days of the invoice date. For consumers, the right of withdrawal in Section 7 applies.
6. Performance and delivery
I perform on a best-effort basis within the scope we agreed. Any timelines are indicative unless expressly agreed as binding. The documentation is delivered digitally.
7. Right of withdrawal (consumers)
Withdrawal instruction
You have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period is 14 days from the day the contract is concluded.
To withdraw, inform me (Ilja Bytschok-Edler von Hoessle, c/o POSTFLEX PFX-230-074, Emsdettener Straße 10, 48268 Greven, Germany, hello@ilja.tax) by a clear statement, for example an email. You may use the model form below, but you do not have to. Sending the notice before the period ends is enough to meet the deadline.
Consequences. If you withdraw, I refund all payments received from you without undue delay and within 14 days, by the same means you used. If you asked me to begin during the withdrawal period, you owe a reasonable amount for the work already done up to your withdrawal, in proportion to the full scope agreed.
Early start. If you expressly ask me to begin before the 14 days end and confirm that you know your right of withdrawal ends once I have fully performed, your right of withdrawal lapses on complete performance.
8. Model withdrawal form
(Complete and return this only if you wish to withdraw.)
To: Ilja Bytschok-Edler von Hoessle, c/o POSTFLEX PFX-230-074, Emsdettener Straße 10, 48268 Greven, Germany — hello@ilja.tax
I hereby withdraw from the contract for the following service: ____________________
Ordered on: __________ Received on: __________
Name: ____________________
Address: ____________________
Date / signature (on paper): __________
9. Liability
I am liable without limitation for intent and gross negligence, for injury to life, body, or health, and under the Product Liability Act. For slight negligence I am liable only for breach of essential contractual duties (Kardinalpflichten), and only up to the foreseeable, contract-typical damage. Any further liability is excluded. In particular, I do not assume liability for tax assessments, penalties, or interest resulting from your filings.
10. Confidentiality and data protection
I treat your data as confidential and use it only to perform the engagement. Raw data and intermediate calculations are deleted once the contractual obligations are fulfilled, and immediately on request. Only the final documentation and the methodology version are retained. See the Privacy Policy.
11. Final provisions
The version of these Terms in force is the one published here when we conclude an engagement. German law applies; for consumers, the mandatory protections of their EU country of residence remain unaffected. For businesses, the place of jurisdiction is my place of business. Should any provision be invalid, the remainder stays in effect.
