An expense report in a company refers to any document through which an employee requests reimbursement for a business expense paid out of pocket. The manual processing of this document typically takes about twenty minutes per report, longer in case of errors. Digitization and automation have been transforming this process for several years, but a major regulatory change that came into effect in September 2026 redefines how receipts circulate between suppliers, employees, and accounting departments.
B2B Electronic Invoicing and Expense Reports: What Changes Since September 2026
Comparisons of expense management software focus on receipt scanning and automatic data entry. They overlook a structural shift: since September 1, 2026, the reform of B2B electronic invoicing mandates that the invoice is sent directly from the supplier to the company, without going through the employee.
In practical terms, for services between two French entities subject to VAT, the receipt no longer needs to be photographed by the employee. The invoice arrives in the company’s e-invoicing platform, where it can be automatically matched with the declared expense.
This mechanism reduces two major irritants in the reimbursement process: duplicate receipts (the same receipt submitted twice) and data entry errors related to manual transcription of amounts. Expense report solutions that interconnect with electronic invoicing platforms thus gain a clear technical advantage over those that limit themselves to optical character recognition (OCR).
Platforms specializing in managing business expenses are already integrating this flow, such as the one accessible at https://www.been.fr/, which centralizes the collection and tracking of expenses incurred by employees.
OCR, AI, and Automatic Matching: Anatomy of a Modern Expense Report Processing
Optical character recognition remains the technical foundation of most expense report software. An employee photographs a restaurant ticket or a taxi receipt, and the OCR extracts the amount, date, supplier name, and VAT rate.
The next step, more recent, relies on layers of artificial intelligence that go beyond simple reading. The software categorizes the expense (transportation, accommodation, meals), checks its compliance with the company’s internal policy, and flags anomalies even before the manager approves it.
Key Steps in Automated Processing
- Capture of the receipt by photo or direct retrieval via the electronic invoicing platform, depending on the nature of the expense
- Automatic extraction and categorization of data (amount, VAT, type of expense) by OCR and classification algorithms
- Real-time compliance check: the software compares each expense to the limits defined in the company’s expense policy and blocks or alerts in case of exceeding
- Validation by the manager via notification, followed by direct integration into the payroll software for reimbursement on the payslip
A process that used to take several days is reduced to a few hours. The gain is not only in speed: the reliability of the data transmitted to accounting increases, simplifying subsequent tax audits.
Real Cost of Expense Management Software: Beyond the Displayed Price
Rankings of solutions often compare monthly subscription rates per user. This superficial price reflects only part of the total cost. The Observatory of AI Investments in Companies, published in September 2026, indicates that the renewal prices of SaaS software are significantly increasing due to the integration of artificial intelligence features.
This price increase has direct consequences for SMEs and mid-sized enterprises. An expense report software chosen for its attractive entry price may end up costing significantly more after two years if the publisher charges extra for AI modules or raises its rates upon renewal.
Criteria to Check Before Signing
Three points deserve particular attention when choosing an expense management solution:
- The price revision clause upon renewal: some publishers commit to a fixed rate for two or three years, others do not
- The functional scope included in the base price: OCR, bank reconciliation, and accounting export must be included in the standard offer, not as an option
- Compatibility with the electronic invoicing platforms mandated by the reform, a condition for benefiting from the automatic flow of receipts described above
Probative Value of Digital Receipts and Tax Compliance
Digitizing a receipt is not enough to eliminate the obligation to keep the original document. For a digital receipt to have probative value in the eyes of the tax administration, the digital copy must meet specific technical conditions: timestamping, file integrity, fidelity of reproduction.
Compliant expense report software automatically applies these constraints at the time of capture. The employee photographs the receipt, the system generates a timestamped and certified file, and the original paper can then be destroyed without legal risk.
The nuance lies in the fact that not all solutions on the market guarantee this level of compliance. Some merely store an image without certified timestamping, exposing the company in case of an audit. Ensuring that the software meets the requirements of Article A 102 B-2 of the Tax Procedure Book (which governs the digitization of supporting documents) remains a technical precaution not to be overlooked during selection.
Managing expense reports is no longer just about choosing software from a list. The reform of electronic invoicing, the rising SaaS prices related to AI, and the requirements for probative value of receipts redefine the selection criteria. A tool suitable in 2024 may become unsuitable in 2027 if its technical roadmap does not incorporate these regulatory and pricing developments.
