Tensoft — a company of the HSI group — has been building software for local governments and institutions for years. At its core is AdAS, an integrated domain system for local government (effectively an ERP for a city hall: taxes, fees, accounting, budget, HR), complemented by DOKUS — EZD-class electronic document management integrated with ePUAP and e‑Delivery — and HyperView, systems for public space management. They are rounded off by e‑Citizen, GIS, Budget, BIP (Public Information Bulletin) and a waste-fee system.
Websites, stores and portals that talk to your ERP from day one. Website and e-mail hosting on our own infrastructure, Microsoft 365 migrations, ongoing support.
As an authorised iiyama distributor, exclusive METZ Display distributor and EDBAK distributor, we supply partners in six countries. We know the product before it hits the shelf.
Over 200,000 orders in iiyama‑sklep.pl and our foreign stores. Every day means real orders, payments, returns and invoices — on our own processes.
Orders, Allegro and payment-gateway payments, invoices and stock levels flow between the stores and ERP through our own tools — with Comarch ERP Optima in-house, and with any system our clients need to connect. The very same tools our ERP division delivers to clients.
Stores, websites and integrations run on our own infrastructure. That’s why, when a client gets an implementation from us, they get something that has been running our own sales for years.
