Value proposition
Rebuilds the full stack of professional services for SMEs: AI agents handle repetitive bookkeeping, tax and payroll work while licensed professionals review and sign off on results — delivering accounting, tax and payroll in one platform with one owner.
Products and solutions
AI-native platform for accounting (live), tax (live), payroll (live), and legal (coming soon), incorporation services (coming soon). Integral Tax GmbH Wirtschaftsprüfungsgesellschaft is the licensed German audit/tax firm operating on the platform, Integral Services GmbH is the technical platform company.
Unique value
Instead of selling software to accounting professionals, Integral IS the firm: AI agents do the work end-to-end (reconciling invoices/bank transactions, creating postings, preparing payroll runs and tax filings) and licensed experts stand behind every result, with professional reviews fed back to improve automation.
Target customer
Small and medium-sized businesses (SMEs) in Germany, and their owners/founders.
Industries served
Accounting, tax, payroll, HR, legal — professional services for SMEs.
Technology advantage
AI agents prepare bookkeeping end-to-end for more than half of clients, cutting monthly accounting turnaround from weeks to hours; proprietary compliance technology for regulated financial work; professionals at Integral Tax have doubled the clients they can serve.
How they differentiate
Competitors build software tools for existing accounting/tax professionals; Integral instead operates as the licensed firm itself, combining AI agents with in-house licensed professionals to deliver services directly to SMEs.
