Intelligent Expense Categorization
Expense tracking relies on precise, consistent categorization to ensure reliable account reading and effective financial management.
Fasfox builds AI solutions that automatically classify expenses, understand their nature, and assign them to the right accounts and cost centers.

When expenses pile up
Every invoice, expense report, or payment contains critical information for financial tracking—expense type, associated project, cost center, VAT regime. These elements must be identified and classified correctly to guarantee account reliability.
As volumes grow, this task becomes repetitive and time-consuming, with risk of inconsistent or approximate classifications.
Why manual categorization lacks consistency
Manual categorization relies on sometimes implicit rules and individual interpretation of each expense. Two similar expenses may be assigned differently depending on context or who’s handling it, complicating financial analysis and comparisons over time.
After-the-fact checks then require manual corrections and extend closing cycles.
The Fasfox approach to expense categorization
Fasfox develops AI solutions that analyze invoice and receipt content, understand the nature of expenses, and propose consistent categorization. The AI draws on history, defined accounting rules, and observed usage patterns to improve accuracy over time.
Assignment proposals for accounts, projects, or cost centers are presented transparently, with the ability to validate and adjust. The solution adapts to accounting frameworks and internal practices.

- Expenses are collected from existing tools.
- AI analyzes receipts and associated information.
- The nature of each expense is automatically identified.
- Categorization is proposed according to defined rules.
- Teams validate or adjust as needed.
- Categorized data feeds financial tracking tools.
