1. Scope and business customers
These General Terms and Conditions apply to all agreements between Johannes J Voigt, a sole proprietor trading as Johannes Voigt Kollektiv and offering the Prufit service, Bismarckstraße 3–5, 04249 Leipzig, and the customer. The service is exclusively for entrepreneurs within the meaning of Section 14 of the German Civil Code (BGB), legal entities under public law and special funds under public law. No contracts are concluded with consumers. Conflicting customer terms apply only if Prufit expressly accepts them in text form. Individual agreements take precedence over these Terms.
2. Services
Prufit provides services including accounts payable and finance operations, invoice and document reviews, vendor and master-data controls, process and control analyses, internal control systems, operational compliance support, process optimisation, data and quality checks, automation support, and finance and control consulting in non-regulated areas. The specific scope is set out in the proposal, order, statement of work, project description or another individual agreement. Unless a specific result is expressly agreed, Prufit owes the professional performance of the agreed activity, not a particular economic or regulatory outcome.
3. No regulated advice
Prufit does not provide legal advice, tax advice, statutory audit services or other regulated advice. The services do not replace a statutory audit or a customer decision.
4. Review scope and no guarantee
Reviews are performed against the agreed control framework and available information. They are sample-, rule- or risk-based as agreed and do not guarantee the accuracy, completeness or absence of errors in invoices, supplier information or business transactions.
5. Customer responsibility
The customer remains responsible for invoice approval, accounting, tax treatment, payment decisions, statutory duties and final risk assessment. Review results are decision support, not approval or payment instructions.
6. Cooperation
The customer shall provide complete, accurate and timely information, contacts and decisions. The customer shall inform Prufit of changes to its control environment and promptly review delivered results. Additional work caused by missing, late or inaccurate cooperation is charged separately where agreed.
7. Data and system access
The customer shall ensure that it is entitled to provide the data transmitted to Prufit. Where the customer is the controller, it is responsible for the lawful collection and transmission of personal data. Credentials may be provided only to the extent required. Prufit may require appropriate technical and organisational security measures.
8. Data protection and processing
The parties comply with data-protection law. Where Prufit processes personal data on behalf of the customer, the parties shall conclude a GDPR Article 28 data-processing agreement (DPA). The customer remains controller; Prufit acts as processor on instructions and provides agreed assistance with rights, security and records.
9. Software, automation and AI
Prufit may use software, OCR technologies, automation, artificial intelligence and other digital tools to provide the services. Automated outputs may be inaccurate or incomplete and, where required, are validated or supplemented within the agreed scope. Automated systems cannot guarantee absolute freedom from error. Prufit may replace providers or technical systems provided this does not materially impair the agreed scope.
10. Third parties and subcontractors
Prufit may use qualified subcontractors and technical providers where required for performance. Data-protection requirements are observed and the customer is informed of subprocessors where legally required.
11. Contract formation
Prufit proposals are non-binding unless expressly stated otherwise. A contract may be formed by written or electronic acceptance of a proposal, placing an order, signing an agreement, confirmation by email, or commencement of services following an instruction. Information on the website does not generally constitute a binding contractual offer.
12. Prices and VAT
The prices in the proposal or individual agreement apply. Prufit applies the small-business treatment pursuant to Section 19 of the German VAT Act (UStG). No VAT is added to the stated prices or shown on invoices.
13. Invoicing
Prufit may invoice one-off services after performance and recurring services monthly. Additional services and agreed additional work are invoiced separately.
14. Payment period
Invoices are payable without deduction within 14 days of receipt. Statutory consequences of default apply. After reasonable notice, Prufit may suspend services until overdue amounts are paid.
15. Change requests
Changes or extensions require agreement in text form. Prufit will state effects on fees and dates; the existing services continue until agreement.
16. Deadlines
Deadlines begin only once all required information and cooperation are available. Agreed dates are reasonably extended for customer-caused delays or force majeure.
17. Confidentiality
Each party keeps the other party's confidential information secret and uses it only to perform the agreement. This excludes public information, information lawfully obtained from third parties, and legally required disclosures. The duty survives termination.
18. Work product and rights
After full payment, the customer receives a non-exclusive right to use work product created specifically for it for its own business purposes. Prufit's general methods, models, frameworks, templates, processes, automation logic, software components and know-how remain with Prufit. Such materials may not be resold, sublicensed or published without Prufit's prior consent.
19. Defects
The customer shall notify Prufit of apparent errors or deviations in work product without undue delay. Prufit first receives the opportunity to correct a justified error within a reasonable period. Where a contract for work has been agreed, mandatory statutory warranty rights remain unaffected.
20. Liability in principle
Prufit is fully liable for intent, gross negligence, injury to life, body or health, and mandatory statutory liability. For slight negligence, liability exists only for breach of essential contractual duties.
21. Liability cap
For slight negligence, liability is limited to the damage typically foreseeable when the contract was concluded and, where legally permissible, additionally to the net fee paid for the affected engagement. Liability for indirect damage, lost profit, unrealised savings, production loss, business interruption or other consequential damage is excluded in cases of slight negligence to the extent permitted by law. These limitations apply correspondingly for Prufit's employees, representatives, agents and subcontractors.
22. Exclusions
Prufit is not liable for damage caused by inaccurate, incomplete or late information, failure to follow recommendations, customer intervention, or systems and networks outside Prufit's control.
23. No liability for business decisions
Prufit is not liable for the customer's approvals, payments, supplier decisions, postings, tax treatment or other business decisions. The customer must assess results independently.
24. Force majeure
Neither party is liable for non-performance caused by events beyond its reasonable control, including natural events, war, strikes, official measures, or power and telecommunications failures. The affected party shall notify the other promptly.
25. Term and cancellation
Individual agreements run for the agreed term. Unless otherwise agreed, recurring agreements may be cancelled with four weeks' notice to the end of a month. The right to terminate for good cause remains unaffected.
26. Set-off and retention
The customer may set off only undisputed or legally established claims. A retention right exists only for claims arising from the same agreement and only to the statutory extent.
27. References
With prior consent, Prufit may name the customer as a reference. Names, logos and case studies are not used without consent.
28. Non-solicitation
To the extent legally permissible, during an ongoing project the parties shall not specifically induce employees of the other party to terminate their employment. General job advertisements and non-targeted applications remain unaffected.
29. Assignment and electronic communications
Assignment of claims under an agreement with Prufit requires Prufit's prior consent unless mandatory law provides otherwise. The parties agree to communicate by email and other agreed electronic channels. The customer acknowledges that electronic communications cannot be completely protected against risks such as misdirection or technical attacks despite appropriate safeguards.
30. Governing law, jurisdiction and final clauses
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If the customer is a merchant, public-law entity or special public-law fund, Leipzig is the exclusive place of jurisdiction to the extent permitted by law. If any provision is invalid, the remainder remains effective and the statutory provision applies in its place. The German version controls; translations are for convenience only.
