DesignSilc is a global ISP software development company with teams in Dhaka, Austin and the UK, serving clients in 38+ countries. We build billing, customer management and network automation software for broadband providers, WISPs, fibre operators and bandwidth resellers. Our systems connect billing directly to MikroTik routers and RADIUS servers, so when a subscriber pays by card, Stripe, PayPal or a mobile wallet the line is reactivated automatically, and when a package expires it is limited or disabled without anyone touching the router. Founded in 2015, we have 70+ developers and 1,000+ delivered projects.
Growing ISPs usually outgrow spreadsheets and generic billing tools quickly: hundreds of resellers, thousands of PPPoE users, collection agents in the field and a support line that never stops ringing. We build software around your actual network and business model, whether you sell to home users, corporate clients or sub-resellers, with tax handling from sales tax in the USA and VAT in the UK to NBR VAT in Bangladesh. We can start with billing, then add modules in phases. Every ISP system now comes with AI built in: it predicts churn, triages tickets, pinpoints fibre faults and lets your own AI assistants check subscribers and sessions through a secure MCP server.
Systems that tie your network, billing, resellers and support team into one source of truth.
Package-based recurring billing, prorated charges, discounts, due reminders by SMS or email and automatic disconnection or speed limiting on expiry.
Create, suspend and change PPPoE or hotspot users from the billing panel via MikroTik API and RADIUS, with real-time online status.
Multi-level reseller and POP accounts with their own balances, packages, commissions and branded customer lists.
Subscribers check usage, pay bills by card, Stripe, PayPal or mobile wallet, change packages and raise tickets without calling.
Ticket queues, SLA timers, outage broadcasts by SMS and a history of every complaint per connection.
Track ONUs, routers, cable and fibre stock per area, plus cash collected by field agents with daily reconciliation.
AI watches billing, RADIUS sessions and OLT signals so your team acts before customers call. It flags who may leave, where a fault sits and which plan fits, and your staff decide what happens next.
Ask in plain words who is unpaid, which NAS is overloaded or why a line dropped, and get the answer from live data.

We build Android-first apps for both sides of an ISP business. The customer app lets subscribers pay online, see their package and expiry date, and raise support tickets in their preferred language. The field technician app gives your team assigned jobs, maps, new-connection forms with photos and signature, ONU serial capture and offline mode for areas with weak signal. Collection agents can record cash receipts and print or SMS a confirmation.

Learn more →Yes. DesignSilc integrates ISP billing with MikroTik RouterOS through its API and with RADIUS servers such as FreeRADIUS. The system creates PPPoE or hotspot users, assigns speed profiles, and disables or limits users on expiry automatically. It works across multiple routers and POPs, which suits the way most regional ISPs and WISPs run their networks.
Cost depends on subscriber volume, number of routers, reseller levels and which modules you need, such as ticketing or field apps. DesignSilc gives ISPs in the USA, UK, Middle East and South Asia a fixed quote after a free discovery call. Many ISPs start with an MVP covering billing, MikroTik sync and online payments, then add reseller portals and mobile apps in later phases.
A first release with billing, customer records, MikroTik or RADIUS integration and online payment typically takes 8 to 14 weeks. Reseller portals, ticketing and technician apps can follow in further phases. DesignSilc also plans data migration from your current spreadsheets or software so subscribers are not disrupted during the switch.
Yes. DesignSilc connects ISP billing to gateways such as Stripe and PayPal, and to bKash and Nagad in Bangladesh. When a payment is confirmed, the invoice is marked paid, the expiry date is extended and the user is re-enabled on the router within moments, with an SMS or email receipt. This removes most of the late-night reconnection calls growing ISPs deal with.
Yes. DesignSilc builds multi-level reseller structures where each reseller or POP has its own login, balance, packages, pricing and customer list. Parent accounts see consolidated revenue and can set commission rules. Resellers can recharge their balance online and manage their subscribers without needing access to your core routers.
Our ISP platforms include an AI copilot for billing and NOC staff, churn prediction with retention suggestions, package recommendations from real usage patterns, mobile wallet and bank payment matching, fibre fault localisation from OLT and ONU signals, NAS load and bandwidth forecasting, ticket triage with automatic line checks and a troubleshooting chatbot for subscribers. Support calls can be transcribed and summarised on the ticket, and reminder or outage SMS are drafted within one message length for your team to send.
Yes. An MCP server is included, exposing tools such as subscriber lookup, live sessions, unpaid bills, ONU signal levels and the ticket queue. Claude, ChatGPT, Cursor or agents built by your engineers connect with the permissions of the user they act for, so a reseller's assistant cannot see another reseller's customers. Changes like package switches, payments or purchase orders are prepared as drafts and need a person to confirm. Every request is logged, and you choose the AI model, whether a cloud service or one hosted on your own servers.
