What Provasis does

Prosvasis, legally operating as ENTERSOFTONE ΑΝΩΝΥΜΗ ΕΤΑΙΡΕΙΑ (ENTERSOFTONE A.E.), is a Greek business software vendor founded in 2005 and headquartered in Kallithea (Athens), with a secondary office in Thessaloniki. The company operates as a subsidiary of SOFTONE TECHNOLOGIES S.A., within the broader SOFTONE group of companies. In December 2024, ENTERSOFT and SOFTONE PROSVASIS announced a merger to form a National Champion in Greek business software.

Prosvasis develops and distributes cloud and on-premises accounting, tax compliance, payroll, and electronic invoicing software for the Greek market. Its two anchor products are PBS ONE (ENTERSOFTONE Accounting Suite), a comprehensive on-premises/cloud accounting platform for accounting firms covering double-entry and simplified bookkeeping, payroll, fixed assets, electronic tax return filing (E1–E9, ΦΠΑ, Intrastat), and myDATA compliance; and ENTERSOFTONE GO, a SaaS cloud application for freelancers and SMBs offering certified electronic invoicing, CRM, expense tracking, and POS/banking integrations. The platform is hosted on Microsoft Azure and is built on a certified AADE electronic-invoicing license with mandatory 5-year document archival and real-time myDATA transmission. Add-on modules include the ENTERSOFTONE POS Connector (epay, Worldline/Cardlink), OnePay real-time bank collection via National Bank of Greece, the GO Skroutz marketplace connector, ESDP digital delivery notes, ERGANI employment compliance, Calculus/Paycheck payroll, and the Anazitisis legal/regulatory research tool. The company is ISO/IEC 27001:2022 certified by TUV AUSTRIA HELLAS.

Revenue is generated primarily through subscription-based SaaS and on-premises licensing (ENTERSOFTONE GO plans priced €5–€144/year; PBS ONE with tiered discounts), mandatory certified e-invoicing provider fees (€72/year), module add-ons (POS Connector, Skroutz, OnePay), and ancillary professional services including seminars, training, and publications. The go-to-market is hybrid: direct self-service SaaS signup for SMBs (15-day free trial), direct sales plus a nationwide network of authorized resellers for accounting firms, and OEM-style embedding into POS/banking partner offerings. The company serves approximately 4,500 accounting offices and 200+ individual accountants in Greece, with downstream SMB and freelancer end-clients, and reports answering roughly 100,000 specialized consulting questions annually.
