AI-Agent Accounting records receipts automatically. AI suggests accounts, reconciles payments and recognizes invoice numbers. The question is no longer academic: what is left for accountants? The answer: more than expected, but different than before. AI takes over routine tasks - scanning receipts, reading out data, suggesting standard postings. What remains is control instead of recording. The E-bill automates the receipt, OCR reads the receipts, banking integration reconciles payments. What cannot be automated: Making decisions. Actively managing liquidity, strategically setting margins, assessing risks, recognizing cross-financing. 2026 is the year in which it will be decided whether accounting continues to tick off receipts - or becomes financial management. Those who tackle the right projects now will shift the focus from administration to management. Those who only implement software will gain speed. Those who rethink processes will gain insights.
The e-bill is more than just a format change
The obligation to receive has been in force since January 1, 2025. Theoretically. In practice, many companies have created a transitional solution: E-invoices are received, manually converted to PDF and processed as usual. This still works. From 2027, companies with a turnover of over EUR 800,000 will be required to send invoices, and from 2028 for everyone. Then the transitional solution will no longer be sufficient; end-to-end processes will be needed from receipt to posting to payment. Media disruptions will become a bottleneck.
The two formats approved in Germany are fundamentally different. XRechnung is pure XML - machine-readable, illegible for humans. ZUGFeRD combines PDF with embedded XML. People can read the PDF, machines can process the XML. ZUGFeRD is gaining acceptance in the B2B sector, not because it is technically superior, but because it is downward compatible. Anyone who cannot yet process an e-invoice will at least see a PDF. With XRechnung, they see a mess of data. Public clients usually require XRechnung. If you need to operate in both worlds, you need software that can process both formats. Not all accounting software can do this.
The real challenge lies in input tax deduction. An incorrect e-invoice does not entitle you to deduct input tax. Accountants have visually checked PDF invoices: Invoice number present? Tax number correct? Service described? With e-invoices, they only see what the software displays. If the software passes incorrect data, this only becomes apparent during the tax audit. Then the input tax deduction is lost, interest accrues and the auditor takes a closer look. Software that automatically validates mandatory data is not a convenience function, but a compliance necessity.
Accounting software: When marketing overtakes reality
Ten years of cloud accounting have changed expectations. Software used to be a tool that you bought, installed and used. Today, software is a service that you subscribe to, that changes constantly, that stores data in external data centers. The first generation of cloud users is taking stock. Reports are piling up in forums and industry discussions: software that slows down as the number of documents increases. Support that refers to known bugs without a timetable for fixing them. Functions that suddenly become chargeable. Data that is deleted after termination.
Some cloud solutions were developed for freelancers and later expanded for more complex requirements. This can be seen in the chart of accounts. SKR03 is usually fully available, SKR04 often only partially. Individual accounts are missing or incorrectly assigned. This only becomes apparent when the tax consultant wants to post to a specific account that does not exist. Then he gives tricks: post to a similar account, note in the notes what was actually meant. This works until the tax audit.
The GoBD requires three things: immutability, completeness and availability. Specifically, this means no subsequent changes to postings, complete documentation of all business transactions and access to data within minutes. Some cloud providers delete data after the end of the contract, which violates the 10-year retention obligation. You either need an export in an audit-proof format or a guarantee that data will remain available even after termination. Ask explicitly before signing the contract.
What saves more time in practice than automatic categorization are batch postings. Categorizing and posting 50 similar bank transactions individually takes time. Processing all 50 at once reduces the effort by 80 percent. Not all systems offer batch postings, some only in more expensive packages, others not at all. With more than 100 transactions per month, this is not an additional function, but is crucial for productivity.
The banking integration is often advertised as a killer feature. Automatic account statement retrieval saves manual export from online banking. The time saved is marginal. The real benefit lies in automatic payment reconciliation: incoming payments are automatically assigned to open invoices. This works via the invoice number in the payment reference, amount, customer number or IBAN. If your customers do not enter the invoice number, the software does not assign anything. The automatic process is then worthless.
OCR transforms document chaos into structured data - if the processes are right
Optical Character Recognition recognizes text from scanned documents. Modern systems achieve a recognition rate of over 98 percent for clean, structured documents. OCR is worthwhile from around 200 documents per month. Below this, manual capture is usually faster than error correction. Above this, OCR pays for itself within a few months. Entering a receipt manually takes 2-3 minutes, OCR reduces this to 10-20 seconds checking time. With 500 receipts per month, that's a time saving of around 15 hours.
OCR does not fail because of the technology, but because of unstructured incoming mail. When invoices arrive by post, email (5 different addresses), fax, portal and WhatsApp, OCR is only of limited help. The upstream software first has to find out where the invoice is before it can process it. First consolidate receipts, then implement OCR. A central e-mail address for all invoices with automatic forwarding to the OCR system is ideal. Suppliers need to know: Invoices only to this address. Other channels are no longer monitored.
The alternative is to check five e-mail inboxes, a fax machine, a letterbox and two portals every day. This takes more time than sending an email to all suppliers: „Please send invoices to rechnungen@example.com in future“
Good OCR systems learn which accounts certain suppliers are typically posted to. After 3-6 months of training, the automation rate is 60-80 percent. The limit: New suppliers, unusual postings, split postings must be reprocessed manually. 100 percent automation is unrealistic.
If your tax consultant uses DATEV, you need a clean interface. Export in DATEV format is usually sufficient. Important: Receipts must also be exported, not just posting data. Some OCR systems only export posting records, but not document images. You then have to transfer receipts separately, which destroys the automatic process.
Receivables management is liquidity management
The average payment period in Germany is 30-60 days. At 4-5 percent interest, every day becomes a real cost. Not in opportunity costs that can be argued away, but in actual financing interest on the current account. Standard in many companies: First reminder on due date plus 14 days. Professional dunning starts at the due date plus 1 day.
The objection: „That scares customers away.“ The reality: Automatic, polite payment reminders are perceived as a service by customers who are willing to pay. They have forgotten the invoice, the reminder helps. Late payers do not change their behavior through goodwill. On the contrary: they learn that they can pay later with you than with competitors. In the event of liquidity bottlenecks, they pay the others first.
Direct debits reduce the payment term to zero. You debit on the due date, the customer doesn't have to do anything. No login to online banking, no bank transfer, no forgotten invoice. The hurdle: customers must issue a SEPA mandate, which requires active contact. This is best done when the contract is concluded, not retrospectively. Do not offer direct debit as an option, but as standard. Other payment methods only at the customer's request.
A 2 percent discount with a 7-day payment term corresponds to over 40 percent annual interest from the customer's point of view. Nevertheless, cash discounts are often used because they immediately improve liquidity. The calculation from your point of view: 2 % discount costs margin, but saves interest costs for tied-up capital (4-5 %), dunning costs, default risk and accounting costs. Discounts are almost always worthwhile for customers with a good credit rating. Even more so for customers with a poor credit rating. 2 % cash discounts are cheaper than 100 % bad debt losses.
Automatic reporting shows daily overdue receivables by age, by customer and by size. Large, overdue receivables from unreliable customers require immediate escalation. Small receivables from reliable customers can wait.
Merchandise management ties up capital that is lacking elsewhere
Stocks cost interest, storage space and carry the risk of obsolescence. After years of zero interest rate policy, these costs are relevant again. One euro in stock is one euro that is not available for investments, debt reduction or liquidity cushions. The ABC analysis categorizes articles according to value share: A articles account for 80 percent of sales with a high turnover rate. Close control and possibly just-in-time are worthwhile here. B articles account for 15 percent of sales with a medium turnover rate. Safety stocks for 2-4 weeks. C articles account for 5 percent of sales with a low turnover rate. This is where the greatest optimization potential lies.
The question is not „How do I optimize C-items?“, but rather: „Do I need C-items at all?“ Many C-items are only sold 1-2 times a year, but block warehouse space and capital. The margin does not cover the storage costs.
Inventory turnover is calculated as annual sales (purchase price) divided by average inventory. Optimization: Increase inventory turnover by reducing slow-moving items or ordering smaller quantities more frequently. The goal is not maximum inventory turnover, but optimal inventory turnover - as high as possible without delivery bottlenecks.
With consignment, the supplier stores with you but remains the owner. You only pay for what you take out. This works for large suppliers with the appropriate financial strength, regular, predictable consumption and sufficient volume. The supplier bears the capital risk, you bear the storage space.
Modern inventory management shows inventory turnover per item, capital commitment per item, stock range and obsolescence risk. This data does not need to be analyzed manually. The software should automatically warn you if items are lying around for too long. If you ignore the warning, this is a conscious decision. If you do not receive the warning, it is ignorance.
Price calculation: Where the greatest levers remain unused
Most companies know what their products cost. Very few know what their products really cost. A medium-sized precision tool manufacturer in Hesse calculated for years on the basis of material costs, production time and flat-rate overhead surcharges. The system worked, the figures looked solid. Until a detailed analysis showed that 30 percent of the product portfolio was operating below its actual costs. The profits from other products were cross-financing the losses without anyone noticing.
The problem lies in simplified Calculation models for list prices. Overheads are allocated on a flat-rate basis, usually according to turnover or production time. As soon as the portfolio becomes more complex - different production processes, different machine utilization, varying set-up times - flat-rate allocation leads to systematic miscalculations. Products with high production times and low complexity subsidize products with low production times and high complexity. Competitors undercut seemingly profitable products, while loss-making ones are left without a fight. The company loses at both ends.
The solution lies in granular cost allocation. The tool manufacturer implemented an SAP Business One interface that recorded set-up and cycle times per product. Machines were equipped with sensors that recorded actual power consumption, running time and downtimes. Payroll accounting was connected so that personnel costs could be allocated per production step. The result: an automated price calculation that learns from internal cost structures. Material costs from the ERP, production times from machine recording, personnel costs from payroll accounting, machine costs from depreciation plus actual energy consumption plus repair costs. Overhead costs are not distributed as a lump sum, but allocated according to actual usage.
The formula takes into account all cost drivers: material costs, direct production costs (personnel, machine, energy), indirect production costs (set-up time, scrap, rework), packaging and shipping, distribution costs (different for each channel), administrative costs (according to expenditure, not flat rate) and imputed risks (warranty, complaints). This results in the cost price limit, above which lies the target margin. After implementation, it became clear that 18 products were below cost price and a further 120 below the strategic target margin. The reaction was differentiated. Products below cost price were adjusted in price (where the market allowed it), optimized in the process (where cost reduction was possible) or discontinued (where neither worked). Products below the target margin were checked for cross-selling potential. Anyone who buys a loss-making product but regularly orders high-margin follow-up products is allowed to keep it.
The result after two years: The overall margin rose by 4.2 percentage points. Not because prices were increased across the board, but because loss-makers were eliminated, high-margin products were strengthened and prices were more differentiated. The portfolio was reduced from 2,400 to 1,800 products, sales remained stable and profits increased. The freed-up production capacity was allocated to higher-margin products. For smaller companies with a large product portfolio, the message is clear: flat-rate overhead surcharges lead to systematic miscalculations. Granular cost allocation is time-consuming, but it pays off. The technology exists, the data is usually available, it just needs to be linked. As long as the overall figures are correct, it is not noticeable that internal cross-financing is taking place. Until a competitor attacks precisely the profitable products and the unprofitable ones remain.
ERP migration comes from the end of support, not from innovation
Many ERP manufacturers are discontinuing support for older versions. SAP, Microsoft, Sage - manufacturers are pushing into the cloud or onto new versions, forcing migration regardless of whether you are happy with your system. SAP: Support for SAP ECC6 runs until 2027 with extended support until 2030, migration to S/4HANA required. Microsoft Dynamics: on-premise versions are becoming increasingly unattractive, cloud migration is being pushed. Lexware, DATEV, SageAnnual updates often mandatory for support. 13 tools for digital invoice approval we have compiled for you.
Check your contracts. If the end of support is in sight, plan your migration now. Service providers will be overloaded in 2027, prices will be higher and implementation quality will be poorer.
On-premise is worthwhile if you have a stable IT infrastructure, long-term planning (use the system for 5-10 years), sensitive data and a one-off investment instead of ongoing costs. Cloud is worthwhile without your own IT department, with multiple locations, with growing employee numbers and for rapid implementation. The cost issue: Cloud is usually more expensive over 5 years than on-premise. However, maintenance, updates and server hardware are eliminated. Do the math with real figures.
Complete data migration is expensive and error-prone. It often makes more sense to migrate master data (customers, articles, suppliers), archive transaction data (orders, postings) in the old system and start clean in the new system. The rule: migrate data that you need on a daily basis. Archive data that you only need for queries.
Typical interfaces: Online store, banking software, time recording, CRM system, merchandise management (if not integrated in the ERP). Before choosing an ERP, check whether these interfaces are available. Standard interfaces are usually free or inexpensive. Individual interfaces quickly cost 10,000-50,000 euros per interface.
Tax audits become digital, gaps are immediately apparent
The tax authorities are increasingly using software for audits. Gaps in archiving are immediately apparent. What used to be tolerated now leads to additional demands and extended audits. The GoBD requires completeness (all tax-relevant documents must be archived), immutability (documents may no longer be changed after storage), traceability (every business transaction must be traceable from receipt to posting) and availability (documents must be retrievable within minutes).
Tax-relevant emails must be archived: E-mails with contract agreements, price agreements, orders, order confirmations and invoices attached. The challenge: you need to be able to decide which emails are relevant. Manual archiving is prone to errors, automatic archiving of all emails creates data waste and conflicts with the GDPR. Automatically archive emails with certain subject lines or from certain senders, decide the rest manually. It's not perfect, but it's practicable.
10 years retention period for accounting documents, invoices, annual financial statements, inventories, management reports. 6 years for business letters and other documents. The software should automatically warn you when retention periods expire. Manually checking which documents can be deleted costs time and leads to errors.
Auditors are increasingly requiring digital data files instead of paper files. Standard formats: GoBD export or DATEV format. Preparation: Complete export of all journal entries and supporting documents for the audit period, procedural documentation (how your accounting system works), Account assignment is traceable (Why was it posted to Account X?) Companies that cannot provide this information within 1–2 days will come under suspicion.
PSD2 forces banking modernization
PSD2 requires strong customer authentication, old banking software no longer works. No more transfers with password only. You need two-factor authentication: TAN via SMS (is blocked), TAN via app (standard) or TAN via hardware generator. Legacy software without this support is useless.
Incoming payments are automatically assigned to open invoices via the invoice number in the note to payee, amount plus customer or IBAN matching. The prerequisite: customers must specify the invoice number. If 50 percent do not do this, you must assign 50 percent manually.
The strategy for supplier payments: Discount payments (if liquidity available), critical suppliers (monopoly position, long delivery times), payments due chronologically, accommodating suppliers last. Modern banking software can suggest this automatically.
Automatic liquidity forecasting is based on open receivables (when money comes in), open liabilities (when money goes out) and recurring payments (salaries, rent, insurance). The software should warn you if liquidity falls below a defined minimum, ideally 14 days in advance. Then you have time to react: Collect receivables, postpone payments, use current accounts.
Compliance is risk management
GoBD, GDPR, e-invoicing, minimum wage documentation - the requirements are growing. GoBD violations lead to assessment notices, extended tax audits, additional payments plus interest. GDPR violations lead to fines of up to 20 million euros or 4 percent of annual turnover. E-invoice violations lead to a lack of input tax deduction, delays and additional work. The costs cannot be quantified until a claim is made.
The GoBD requires procedural documentation: organizational structure (who posts, who checks, who approves), IT systems (which software, which interfaces), data backup (how often, where, how is recovery tested), document flow (how does an invoice get from receipt to payment) and access rights (who is allowed to do what). Most companies do not have up-to-date procedural documentation until the audit. Then it is written up in 48 hours: superficial, inconsistent, impractical.
Accounting data is personal if it can be assigned to individuals: Salary data, customer data, supplier data (for sole proprietorships). The requirements: Access only for authorized persons, encrypted transmission, deletion after expiry of retention periods, right to information (data subjects can request data).
Typical weak points: incomplete Document archiving, missing procedural documentation, unregulated access rights, no data backup or untested recovery, emails not archived. An internal compliance check by a tax consultant or external advisor costs 2,000-5,000 euros. A tax audit with a finding of deficiencies costs ten times as much.
Employees make software successful
New software only helps if employees can and want to use it. Failed digitization projects rarely fail because of the technology, they fail because of a lack of acceptance. Software is rejected if it is more complicated than the old system, if no one has explained why a change is being made or if employees have not been involved. The people who work with the system on a daily basis know better than the management what works and what doesn't.
One-off training after go-live is not enough. After 3 months most of it is forgotten, what remains are the 5-10 functions that are used daily. Video courses for specific tasks (2-3 minutes), an internal FAQ database, power users as contact persons and regular updates on new functions work more reliably than one-off training courses. Employees who have mastered the system work faster, make fewer mistakes and are more satisfied.
Many processes only exist in the minds of individual employees. If the person leaves or resigns, the knowledge is gone. It then takes months instead of weeks to train new employees. A central knowledge database with standard posting templates, account assignment logic for typical business transactions, checklists for monthly and year-end closing and contact persons for special cases reduces this dependency.
Resistance arises when change is perceived as a threat. This happens when employees do not understand why changes are being made, when they fear becoming redundant or when they do not feel heard. Transparency about reasons, job security and involvement in decisions reduce resistance.
2026 decides who works relaxed in 2028
2026 will not bring any spectacular innovations, it will bring obligations: e-billing from 2027, modernized Banking software through PSD2, stricter audits through digital tools. Those who use 2026 to prepare work under controlled conditions. Test phases run parallel to regular operations, errors are detected before they become critical, employees have time to familiarize themselves, service providers have capacity. Those who wait 2027/2028 work under time pressure.
The levers are known, the technologies are available. What is missing is implementation - not all ten topics at the same time, but the three that are crucial for your business model. A retail company with a high number of items and many transactions must prioritize merchandise management and receivables management. Capital tied up in stock and outstanding receivables are the biggest liquidity guzzlers. A service provider with project-based work and few but large customers must ensure accounting software and document management. Compliance risks are higher because errors in large projects have a greater impact. A manufacturing company with complex production processes and supply chains needs end-to-end ERP and stable processes. Media disruptions between purchasing, production and sales destroy efficiency.
The question is not: What is modern? The question is: What reduces risks and improves liquidity? The answer lies in sober calculation: Which investment will pay off in three years? Which process change will measurably reduce costs? Which compliance measure will specifically reduce risks?
The e-bill is coming. Interest rates are here to stay. Auditors are becoming more digital. You decide what you do with it. Now, not in 2027.
