Software Introduction

Purpose-built billing software for ISPs and WISPs

Tamim ISP Billing System replaces spreadsheets, sticky notes, and manual router logins with a single platform that understands how ISPs actually make money: subscriptions, packages, and uptime.

Built for real ISP workflows

Package tiers, prorated upgrades, grace periods, and bulk actions — modeled on how billing teams actually work.

Connects to your existing hardware

MikroTik routers and GPON OLTs sync directly — no rip-and-replace of your network.

Self-hosted, fully yours

Install on your own server. Your client data never leaves your infrastructure.

Features

Everything a modern ISP dashboard needs

Twenty tools that cover billing, network control, and day-to-day operations — no add-on marketplace required.

Modern Dashboard

A live control room for your ISP — revenue, uptime and churn in one glass panel.

Client Management

Onboard, suspend, or upgrade subscribers in a few clicks, with full account history.

Billing System

Flexible billing cycles, prorated upgrades, and automatic late-fee handling.

Auto Bill Generate

Bills raise themselves on schedule — nobody has to remember billing day again.

Invoice

Branded, print-ready invoices generated instantly for every package and add-on.

Money Receipt

Auto-numbered receipts on every payment, searchable by client or date.

Payment History

A full, exportable ledger of every payment a client has ever made.

Package Management

Build speed tiers and bundles once, then assign them in seconds.

MikroTik API

Talks directly to your routers — no manual provisioning, ever.

PPPoE Control

Enable, disable, or throttle PPPoE sessions the moment a bill is paid or overdue.

Queue Management

Simple queues assign the right bandwidth to the right subscriber, automatically.

OLT Management

Monitor and manage GPON ONUs across your OLT fleet from one screen.

Why Tamim ISP

Why ISPs choose Tamim ISP Billing System

Most billing tools stop at the invoice. Ours goes all the way to the router — because for an ISP, billing and network access are the same decision.

Request Live Demo
Billing and network stay in sync

An unpaid invoice can automatically throttle or suspend a PPPoE session — no separate step, no missed disconnections.

One login for the whole team

Billing staff, NOC engineers, and support agents each get exactly the access their role needs.

Priced to scale with you

A lifetime license model instead of a per-client SaaS fee that grows faster than your margins.

Support that knows ISP operations

Our team has actually configured MikroTik queues and OLT ONUs — support tickets don't start from zero.

Accessible Web Portal & Apps

One platform, every user gets their own portal

Dedicated web portals and mobile access for company owners, admins, employees, resellers, distributors and clients.

Company Portal & App

Manage company operations, branches, billing overview and business reports from a dedicated portal.

Admin Portal & App

Full management access for billing, clients, network devices, reports, staff and settings.

Employee Portal & App

Give employees the right tools and permissions for support, billing and day-to-day ISP operations.

Reseller Portal & Apps

Resellers can manage their clients, packages, payments and service operations from their own portal.

Sub-Reseller Portal & App

A focused portal for sub-resellers to manage assigned clients and reseller-level activities.

Distributor Portal & App

Manage distributor operations, assigned resellers and business activity from one place.

Client Portal & Apps

Customers can view bills, package details, payment history, support and online payment options.

Modules

Modules that run the whole operation

MikroTik and OLT integration, billing automation, reporting, and payments — the five modules ISPs rely on daily.

MikroTik Integration

Two-way sync with RouterOS: create PPPoE secrets, enforce speed limits, and disconnect overdue clients automatically the moment a bill goes unpaid.

  • Auto PPPoE provisioning
  • Live session monitoring
  • Bandwidth limit enforcement
  • Instant suspend / resume
OLT Integration

Manage GPON OLT chassis and ONUs from the same dashboard as billing — see optical signal levels next to the invoice that keeps them online.

  • ONU provisioning
  • Optical power monitoring
  • Fault & alarm alerts
  • Multi-vendor OLT support
Billing Automation

Set it once. Invoices generate, reminders send, and overdue accounts are throttled without a single manual step from your billing team.

  • Scheduled invoice runs
  • Auto late-fee rules
  • Grace-period control
  • Bulk billing actions
Reports

Every number an ISP owner actually checks — daily collection, expiring clients, package popularity — built as a report, not a spreadsheet you build yourself.

  • Revenue & collection reports
  • Expiry & churn reports
  • Staff performance reports
  • One-click CSV / PDF export
Payment Gateway

Accept bKash, Nagad, Rocket, and card payments directly against an invoice, with the ledger updating and PPPoE reactivating the instant a payment clears.

  • bKash / Nagad / Rocket
  • Card & bank gateways
  • Auto reconciliation
  • Client self-service payment portal
