Problem
Tax advisory firms spend extensive manual effort on routine bookkeeping tasks such as invoice entry, bank reconciliation, and document classification, which slows month‑end closing and ties up staff during peak periods.
Solution
Jessy Works offers an AI‑driven bookkeeping assistant that operates directly within the firm’s existing desktop accounting software, particularly DATEV, without requiring any pre‑processing systems. The AI extracts data from incoming documents, automatically assigns accounts, splits complex entries, and posts transactions, handling up to 90 % of monthly bookkeeping work. A built‑in validation layer checks each posting for consistency, and an audit trail records source, time, and action for full compliance. The solution runs as a Windows service on the firm’s terminal server, enabling parallel processing across multiple clients and delivering month‑end results up to 8.7 times faster than traditional manual workflows.
Target Audience
Primary customers are tax advisory firms and accounting departments that use DATEV or similar desktop bookkeeping software and need to accelerate month‑end processing while maintaining regulatory compliance.
