Everything about the client in one place
ISPadmin brings clients, services, the network, billing and technicians’ work together in one system. Technicians on site see the client’s details, the office sees the installation status and management has an overview of the network. Everyone works with the same, up-to-date data.
-
Clients and services
Each client has their own card: services, contracts, invoices, tickets and the history of service visits. In the client portal, clients see their invoices, services and documents.

Network
ISPadmin automatically writes changes made on the client card to MikroTik and Linux routers and to OLTs. Ubiquiti, Cambium Networks and other devices are monitored, and NetMonitor shows what is offline right now.

Billing
You issue invoices in bulk, and ISPadmin matches payments from imported bank statements to them. It sends reminders based on templates and, with the NMM module, can suspend a non-payer’s service and restore it once they pay.

Technicians and support
A ticket from e-mail or the client portal becomes a task in the technician’s calendar. You then invoice the work done and the materials used.
