The GT Mayor is a system of simplified accounting services. We recommend this program to companies keeping a revenue and expense ledger and lump-sum tax payers, who settle in the form of a lump sum on registered revenues. The GT cadastre is an excellent tool for both companies documenting their own business activity and accounting offices.

The program enables easy integration with Subiekt GT - a sales support system for small and medium-sized companies. The database system used in InsERT GT programs is Microsoft SQL Server 2008 R2, which in the free version Express Edition is delivered with the system.
