Bookkeeping · Research allowance · AI in accounting

We don't talk about AI in accounting.
We run it.

Ongoing bookkeeping for German tax firms and companies, the research allowance (Forschungszulage), GoBD audits and process documentation. What we roll out at your firm runs in our own daily practice — and we build the systems behind it ourselves.

We are not appointed tax advisers (Steuerberater). What we may do and what we may not is on this page, not in the fine print.

1 · Research allowance

It is paid out even if you are making losses.

35 %of eligible expenses for small and medium-sized enterprises — 25 % by default plus ten percentage points that must be applied for

This is the point most funding programmes lack, and it decides everything for a company in its build-up phase: the research allowance does not depend on profit. It is credited against your tax, and whatever remains is paid out.

Since 1 January 2026 the assessment base is €12 million per year, plus a 20 % flat rate for overhead and operating costs. Your own work as a sole proprietor counts at €100 per hour.

First the question whether it is research — then the figure.

The certification body checks exactly three criteria. Answer three questions; the assessment is produced in your browser — nothing is transmitted and nothing is stored.

Three criteria of the certification body

Routine is what a competitor could build the same way with standard tools. Rolling out and configuring existing software, porting, data migration and server set-up do not count.

Taking longer, more test series, commercial questions and data-protection concerns do not count. A nameable plan B with an abort criterion is strong.

Several projects in one application are allowed — each needs its own description. Two projects in one description cannot be assessed.

Assessment on the merits · not a certificate

Answer the three questions.

Benchmark: the audit guide of the certification body (Bescheinigungsstelle Forschungszulage), version 10/2025 — three criteria, not the five popular ones. If one criterion clearly fails, the others are not queried. The assessment replaces no certificate; it tells you whether the next step is worth it.

Source & scope

The three criteria novelty, uncertainty and systematic plan and the delineation from routine (roll-out, configuration, porting, data migration) follow the certification body's audit guide; the admissibility of several projects in one application follows its FAQ. What you tick here is seen by you alone.

Checked against the audit guide: 23.09.2026; editorial: 25.09.2026. All sources

What would your allowance be?

Slide in your numbers. The calculation runs in your browser — nothing is transmitted, nothing is stored.

Assumptions and costs

Only allocated costs under section 3(1)-(2), not total payroll.

Deduct onward subcontract fees first.

Only where section 3(3a) conditions are met; not the full purchase price.

Simplification: constant weekly hours. Sole traders / qualifying partners only.

Model limit: 52 weeks. Assess varying weeks and partial weeks separately.

Sole trader: €100; partners: no more than agreed remuneration, capped at €100.

€12m less usage by other projects / linked companies. Not a separate cap per project.

Modelled amount · not an award

€155,400

Method (2026 model, one project): eligible expenses = staff costs + 70 % (60 % if commissioned before 28 Mar 2024) of the contract fee + eligible depreciation + own work (hours × weeks × hourly rate, at most 40 hours a week and €100 an hour). For projects started after 31 Dec 2025, a 20 % overhead allowance is added on that sum. Capped at the remaining assessment base, at most €12 m including the allowance; 25 % of that, or 35 % for SMEs on request. Sections 3(1)–(5) and 4(1) FZulG. The result is an order of magnitude for the conversation, not a commitment.

The mistake that cannot be repaired afterwards

The anti-cumulation rule in § 7 (2) FZulG is expense-based, not project-based. A project funded through EXIST or ZIM therefore does not exclude the research allowance — but the same personnel expense must not be claimed twice.

That requires expense-accurate time recording from day one. Whoever notices in the application year that it is missing cannot reconstruct it. That is exactly where applications fail that would have held on substance.

How the application works — and what we do in it

Two stages. First the certificate from the Bescheinigungsstelle Forschungszulage (BSFZ) via its web portal — it is a mandatory prerequisite and can be applied for before, during or after the project; the decision usually arrives within three months. Then the application to the tax office after the end of the financial year.

We write the technical project description for your BSFZ application and compile the eligible expenses. The application to the tax office is filed by your tax adviser on the basis of these documents. External advice is expressly permitted in the certification procedure; the adviser is named in the application. Responsibility for accuracy stays with you — which is why you receive documents you can check, not a black box.

Source & scope

The cap is not independently available per project. Linked companies must be considered together under section 3(6). A calculation does not establish project eligibility.

Section 3(3b): overhead on eligible costs under (1), (2), (3), (3a) and (4), only for projects begun after 31 Dec 2025. (5)-(6): cap includes overhead. Section 4(1): SME uplift on application; (3): additional aid limit.

2 · Services

One chain: found, post, automate, fund, audit.

For tax firms

Ongoing bookkeeping — back to you, ready for reconciliation

Financial accounting on behalf of and under the responsibility of your firm — entirely in DATEV, following your posting rules and your chart of accounts. You receive the books ready for reconciliation, with complete working papers on request; posting and preparation of the accounts happen at your firm.

  • Setting up new client files and building charts of accounts to your specifications
  • Automating document processing, rule sets for recurring postings
  • Cleaning up account structures that have grown over the years
  • Working papers for the year-end, reconciled and evidenced

For companies

Bookkeeping on a monthly cycle

Your ongoing bookkeeping, monthly, in DATEV or your own system — coordinated with the firm that prepares your annual accounts. You get usable figures during the year instead of only in the year after.

For founders

From the first calculation onwards

We stay with you into day-to-day operations: financial model and liquidity planning, setting up the bookkeeping, deadlines and filing duties of the first hundred days, choosing and configuring systems, preparing the conversations with bank, tax firm and investors.

Choice of legal form, articles of association and tax structuring belong to your tax adviser and lawyer. We make sure you walk in prepared and that the results get implemented.

For developers

Domain consulting for software development

For developers of accounting software we bring the domain side that most products fail on: posting logic, SKR chart-of-accounts systematics, DATEV interfaces, GoBD requirements on immutability and logging, process documentation as part of the product.

Not as an external consultant next to the team, but inside the development process: rule sets, test cases from real posting data, error classes.

3 · GoBD and process documentation

You won't get a certificate from us. For a reason that works in your favour.

Para. 181"Certificates or attestations by third parties … have no binding effect on the tax authority" — GoBD, verbatim

The German tax administration issues no positive attestations on the regularity of a set of books, neither in a tax audit nor by binding ruling. And third-party certificates do not bind it. The reason sits one paragraph earlier: what matters are updates, access rights and data entry — not the product, but how it is operated and documented at your company.

That is why we audit your accounting and document system against the GoBD and § 146 (4) AO and deliver what actually counts in a tax audit: an audit report with a finding per requirement, named deficiencies and concrete remediation steps — plus the complete process documentation.

Six questions asked in a tax audit

Answer them for your system. Here, too, everything stays in your browser.

ImmutabilityWhen an entry is corrected, does the original content remain ascertainable — and is it evident whether a change was made originally or later?

Traceability of automationIs it documented which rule produced an automatically generated posting — and which version of that rule applied at the time?

Process documentationDoes it exist in full — general description, user documentation, technical system documentation and operating documentation?

Document linkageIs every posting linked to its source document and retrievable from within the system?

Receiving e-invoicesCan you receive, process and retain structured e-invoices in an audit-proof way — mandatory since 1 January 2025?

Change history of the rule setCan you reconstruct who changed which posting rule, and when?

The quick check is no substitute for an audit. It shows where an audit would start. Discuss the open items →

Why we know where to look

We build AI-driven accounting systems ourselves and know the places where they regularly break — because we have to close them while building. § 146 (4) AO requires that "the original content remains ascertainable" and that no change is made "whose nature leaves it uncertain whether it was made originally or only later". That is where automated systems fail — not on posting quality.

We do not audit our own systems. For those we name you an independent auditor. For systems we helped build we issue a manufacturer's declaration — labelled as what it is: a statement by the manufacturer, not an independent audit.

Source & scope

AO (1): orderly records; (4): alterations; (5): availability and readability. The BMF document is the second GoBD amendment, not a complete standalone GoBD text. The questions below are our operational interpretation, not verbatim statutory quotations.

4 · Why now

The figures arrive next year. Decisions are made now.

1 Jan 2025since this day, every German business must be able to receive e-invoices — regardless of all transition periods for issuing them

In tax firms, ongoing bookkeeping piles up while annual accounts wait. In companies, the figures arrive when the financial year is long over. Both have the same cause: the part of the work that is not tax advice ties up the time of those who are supposed to advise.

And the deadlines keep running. The obligation to receive e-invoices has applied since the start of 2025 — the most common misconception in the market is that it only begins with the issuing deadlines in 2027 and 2028. The research allowance was expanded on 1 January 2026, but is granted only on application, and the SME uplift only if it is expressly requested.

5 · AI in accounting

We only roll out what we run ourselves.

§ 203StGB and § 62a StBerG — the question most AI vendors in the German tax market cannot answer

We advise companies that develop and operate AI-driven posting software for DATEV tax firms, and we take part in the development. The rule sets running in production there stem in substantial parts from our work.

Services: building rule sets for automated account assignment · rollout and integration with DATEV · guiding the transition in day-to-day firm operations · review of data protection and professional secrecy under § 203 StGB and § 62a StBerG.

Disclosure: in every system assessment we state our involvement in the products under review before the engagement begins. Systems we helped build, we do not audit.

Rule sets that run with any AI. Our rule sets do not live in a chat history or in a vendor account, but as versioned text editions in a fixed place — with a directory every assistant reads first, and a loud failure when it cannot. We measured this on 24.09.2026: two different AI models, in a fresh conversation without any hint, found the correct rule edition and worked from it; without access to the storage location they said so instead of guessing. That is exactly how we set up rule editions for you — the vendor is replaceable, the rule set stays yours.

Source & scope

Assess necessary access, selection, contractual obligations, foreign services and other participants separately; section 62a(5)-(8) also matters. Data protection law applies alongside these rules. EU hosting alone does not prove lawful processing as a whole.

6 · Reporting

A report in which every figure leads to its evidence.

One clickfrom the group figure to the posting — derivation, monthly values and citation open at the figure itself, not in a footnote

The ongoing bookkeeping produces the report that management, banks and investors actually read: result per entity and consolidated, actual against plan, liquidity with runway, intercompany reconciliation with the remaining difference stated.

A single HTML file. No login, no cloud service, no transfer to third parties. It opens in the browser, works offline and can be forwarded by email. German and English in the same file.

  1. 1Click a figure — every underlined figure is an entry point.
  2. 2Read the derivation — components and monthly values.
  3. 3See the evidence — account, month, posting batch.

The report is built from each entity's trial balance; every figure shown carries its derivation and the reference to account, month and posting batch. Consolidation and valuation remain the task of the firm or the auditor.

7 · Who we are

One human. The staff are systems we build ourselves.

1human — and a team of AI systems we develop, operate and review under § 203 StGB

We say this openly because it answers the question you are asking anyway: how can one person deliver all of this? By having the routines — document processing, account assignment, reconciliation, documentation — run on systems we built ourselves and whose rule sets we know down to the last line.

What that means for you: every decision that concerns your engagement or your data is made by a human. The systems operate under § 203 StGB and § 62a StBerG — with confidentiality agreements, EU hosting and a documented rule set. What they do is traceable; what they may not do is defined.

AI builds AI. We build our systems with the same tools we roll out at your firm. That cycle is the proof that it works — and the reason we know where it breaks.

What we build ourselves

Posting automation for DATEV tax firms

Developed with a partner company and in production in daily firm operations: rule sets for automatic account assignment, test cases from real posting data, error classes that are persisted and checked on every run. Where the system is not sure, it asks — instead of guessing.

What we build ourselves

This page

Conceived, written, legally reviewed, built, tested and published with AI — in one day, including domain, mail infrastructure and data processing agreement. The calculator and the quick check run without a server, without trackers, without a single external resource. You are looking at the work product, not the brochure.

8 · Who does what

What we may do is here. What we may not do, too — and who does it instead.

We are not appointed tax advisers (Steuerberater) and provide bookkeeping services within the limits of § 6 of the German Tax Advisory Act (StBerG) as in force since 1 September 2026. That is not a restriction we hide; it is the division of labour the whole chain rests on: for every stage it is defined what we do, what we hand over and who carries on with responsibility. Nothing falls between two stools — that is why tax firms can work with us.

The chart of accounts we used to build under the firm's responsibility we now set up on our own.

Whoever offers you, as a bookkeeping service, the annual accounts and the tax return as well is offering you something § 5 StBerG forbids them to do. That is why this list sits here and not in the fine print: it is the reason your tax firm keeps its tasks and you know where you stand.

Where your data lives

We store no client documents locally and work exclusively through EU-hosted systems. For client communication we use our principals' addresses, not mailboxes of our own.

Data processing agreements under Art. 28 GDPR are in place for the service providers we use; processing takes place contractually only in the EU or EEA, and any transfer to a third country would require our prior consent. We provide our list of sub-processors and the underlying contracts on request — for your record under Art. 30 GDPR.

Source & scope

Since 1 Sep 2026, the exception also covers setting up charts of accounts. The responsible person needs a commercial vocational qualification or equivalent, followed by at least three years of practical bookkeeping at at least 16 hours per week. Citing the provision alone does not establish GUV's qualification.

9 · Prices

One rate for time. One cap at the top. No small print.

140 €per hour — for closing preparation, review, process documentation, automation and specialist advice alike. A day is seven hours: €980

We do not scale by client size and charge no surcharges. Every fixed price on this page can be recalculated in hours — that is deliberate.

All amounts net. For services to businesses in Germany the reverse charge applies.

Ongoing bookkeeping

Monthly, by document volume, at a fixed price. The time our automation saves is not kept as margin — it goes into better rule sets, tighter reconciliation and the next improvement. The work gets better every month. Your price does not.

We do not offer bookkeeping without reconciliation. Books that are not reconciled are not books. Included in the price:

  • capture and coding, complete in DATEV
  • bank postings and clearing of open items
  • account reconciliations, month by month
  • tracking of transit items including chasing the missing invoices
  • the monthly report shown under Reporting — result, key figures, liquidity, every figure with its derivation; German and English
Documents per monthPrice per month
up to 50€400
up to 150€1,000
up to 400€2,200
above thatindividual

Two fixed items come on top — we name them here so no figure follows later:

  • Hosting, €100 per month: the server on which DATEV or our systems run for you.
  • DATEV licence: you pay it directly to DATEV, depending on the package typically around €150 per month (DATEV's gross price). We earn nothing on it.

Closing preparation by time at €140. Above 400 documents a month we name no flat figure, because it would mislead — ask us.

Projects at a fixed price

The price is the estimated effort times €140. If it takes less, we bill less.

Where the 20 hours for the working paper come from

Our reference is the 2025 year-end of a small GmbH, measured on 23.09.2026: 125 general-ledger accounts, 9,670 postings, 42 reconciled balance-sheet accounts, four data gates, a document-request register, a provisions derivation, a VAT reconciliation and the size class. From that, the hours — the quantities are measured, the time per step is our assumption:

Where the 14 hours for the rule edition come from

A rule edition consists of a directory that says which rule is responsible for what, of content editions per rule set, and of a pointer in the respective AI account that knows the way there and says loudly when it cannot find it. It is finished only when a fresh assistant loads the right edition without a hint — we measure that before we bill.

Three test runs in fresh conversations, protocol3 × 1 h3

Maintenance: every change becomes a new edition, never an overwrite; one test run per quarter. For that we allow two hours per month. Each further rule set costs three hours.

Why we do not offer BAFA-funded consulting

Producing a process documentation would in principle qualify as management consulting under the German BAFA scheme. We still do not offer it, and we will tell you plainly why.

The grant is 80 per cent in the eastern federal states excluding Berlin and the Leipzig region, capped at €2,800, otherwise 50 per cent, capped at €1,750. At most €3,500 of net consulting cost per project and at most five consulting days are eligible.

Against that stands this procedure: an application before any contract is signed, no retroactive funding, a review of your SME status and of the consultant's listing by a central office, for young companies an additional preliminary information meeting, and afterwards a consulting report in prescribed form, the invoice, the bank statement and a statement of use.

The maximum grant of €2,800 equals 20 hours of our work. In our assessment the administrative effort on both sides is of the same order, and the project start slips by weeks. We consider this a bureaucracy monster and would rather bill €140 an hour straight away.

If you still want to use the funding, you need a consultant listed with BAFA. We are not, and will not be. Tell us and we will stay out of it.

Research allowance

Two paths, fixed together before the engagement — no surprises afterwards.

Success model for projects from roughly €100,000 of expected allowance: 5 per cent of the assessed allowance, capped at €50,000. If nothing is assessed, you pay nothing. 20 per cent falls due after the positive certificate — the step where applications fail, and which by then you have passed. The rest only once the tax office assesses the allowance.

Hourly model for smaller projects: €140 an hour, effort disclosed before you engage us. An application taking ten hours costs €1,400 — even with an allowance of €10,000, and we put exactly that calculation in front of you first. If the effort is not worth the allowance, we say so in the first conversation — then there is no application, and being told costs nothing.

Assessed allowanceMarket rate 10%With usYou save

€4,200,000€420,000€50,000€370,000

Which path applies is written into the engagement — not decided afterwards. The application to the tax office remains the task of your tax adviser.

That is a function you explicitly requested (§ 25(2) no. 2 TDDDG); you delete the value via your browser's site data.
