Payment Gateways: 20+ Options Across 5 Countries
Subscriber payment preferences vary by region. In Bangladesh, bKash and Nagad dominate mobile financial services. In India, UPI-based flows through Razorpay are the norm. Nepal relies on eSewa and Khalti, while Pakistan runs on JazzCash and Easypaisa. ISPbills now supports gateways across all of these markets — plus international options for cross-border billing.
Bangladesh (8 Gateways)
bKash (Tokenized + Checkout), Nagad, SSL Commerz, ShurjoPay, Aamar Pay, Easypayway, BD SmartPay, and WalletMix. bKash supports two integration modes: the Tokenized API for recurring payments and the Checkout flow for one-time collections. ISPbills auto-selects the correct flow based on your configuration.
India (3 Gateways)
Razorpay, Paytm, and Instamojo. Razorpay covers UPI, cards, net banking, and wallets behind a single integration. Paytm and Instamojo offer alternative flows for ISPs that prefer their settlement terms.
Nepal (3 Gateways)
eSewa, Khalti, and IME Pay. eSewa is the most widely used digital wallet in Nepal, while Khalti and IME Pay are gaining ground rapidly — especially outside the Kathmandu Valley.
Pakistan (3 Gateways)
JazzCash, Easypaisa, and HBL Konnect. JazzCash and Easypaisa together cover the vast majority of mobile wallet users in Pakistan. HBL Konnect provides a bank-backed alternative for direct settlement.
International (3 Gateways)
Stripe, PayPal, and Authorize.Net. These cover card payments globally and are useful for ISPs billing corporate clients or international organizations that prefer USD or EUR payments.
Dynamic Form Fields
Each gateway has its own API keys, merchant IDs, and config options. ISPbills renders the correct form fields automatically when you select a provider.
Sandbox / Live Toggle
Test your integration in sandbox mode before going live. Switch between environments with a single toggle — no code changes needed.
Service Charge Config
Absorb gateway fees or pass them to subscribers as a convenience charge. Set flat or percentage-based charges per gateway.
Operator Inheritance
In multi-operator setups, child operators inherit the parent's gateway config by default but can override with their own credentials.
SMS Gateways: 30 Providers Across 5 Countries
SMS remains the most reliable channel for reaching ISP subscribers in South Asia. Payment reminders, OTP verification, outage notifications, and welcome messages all depend on a working SMS pipeline. ISPbills now integrates with 30 providers so you can choose the best rates, delivery performance, and regulatory compliance for your market.
Bangladesh (18 Providers)
Maestro, Robi, M2MBD, Bangladesh SMS, BulkSMSBD, BTS SMS, 880 SMS, BD SmartPay, ElitBuzz, SSL Wireless, ADN SMS, 24 SMS BD, SMS.net, Brand SMS, MetroTel, DianaHost, SMS in BD, and DhakaSoft BD. This deep coverage means you can switch providers without changing a single line of code if your current provider raises rates or experiences delivery issues.
India (3 Providers)
TextLocal, MSG91, and Karix. All three support India's DLT (Distributed Ledger Technology) registration requirement, which mandates that every SMS template and sender ID be pre-registered with the telecom regulator before delivery.
Nepal (3 Providers)
Sparrow SMS, Aakash SMS, and Khalti SMS. These providers cover all major Nepali carriers and offer competitive per-SMS pricing for high-volume ISP use cases.
Pakistan (3 Providers)
Jazz SMS, Zong SMS, and Telenor SMS. Carrier-direct integrations offer better delivery rates and lower latency compared to third-party aggregators in the Pakistani market.
International (3 Providers)
Twilio, Vonage (Nexmo), and Plivo. These global platforms are ideal for ISPs operating across multiple countries or needing fallback routing when a local provider is down.
Provider-Specific Field Mapping
Each SMS provider uses different API parameters. ISPbills maps the correct fields — sender ID, API key, secret, route type — automatically for each provider.
DLT Compliance (India)
ISPbills stores DLT entity IDs and template IDs alongside each SMS template, ensuring every message meets TRAI regulatory requirements.
Cost Tracking
Track SMS spend per provider, per month, and per message type. Identify which notifications cost the most and optimize accordingly.
Per-SMS Billing
Optionally pass SMS costs to subscribers or operators. Set per-SMS rates and let the system calculate charges automatically each billing cycle.
OLT Vendor Support: 12 Brands, 3 Integration Tiers
FTTH networks are expanding rapidly across South Asia, and ISPs are deploying OLTs from a wide range of vendors — often mixing brands across different POPs. ISPbills now supports 12+ OLT vendors, organized into three tiers based on integration depth.
Tier 1 — Full SNMP + CLI
VSOL, DBC, and Fiberhome (AN5516/AN5006). These vendors support SNMP monitoring and CLI provisioning. ISPbills can discover ONUs, read optical power levels, configure VLANs, and provision subscribers directly from the dashboard. Fiberhome's AN5516 and AN5006 use a proprietary CLI that ISPbills handles natively, including automatic ONU discovery via SSH.
Tier 2 — SNMP + Running Config
ZTE, Huawei, BDCOM, HIOSO, and Syrotech. These vendors expose full SNMP MIBs for monitoring and support running-config retrieval. ISPbills polls ONU status, signal levels, and uptime via SNMP and parses the running config for topology mapping.
Tier 3 — SNMP Discovery Only
C-Data, Nokia, and Raisecom. These vendors support standard SNMP OIDs for device and ONU discovery. ISPbills detects connected ONUs, reads basic status information, and maps ONUs to subscriber accounts.
Generic — CTC/RFC OID Fallback
For unlisted OLTs, ISPbills includes a generic profile using standard CTC and RFC-compliant SNMP OIDs to discover ONUs and read basic metrics — ensuring even white-label hardware can be integrated without waiting for a vendor-specific update.
Brand Alias System
HIOSO and Syrotech OLTs are VSOL-based under the hood. ISPbills recognizes these aliases and applies the correct VSOL SNMP OID set automatically.
Vendor-Specific SNMP OIDs
Each vendor uses different OIDs for optical power, ONU status, and temperature. ISPbills ships with pre-configured OID maps for all 12 vendors.
Fiberhome CLI Discovery
Fiberhome OLTs require CLI-based ONU discovery. ISPbills automates this via SSH sessions, parsing discovery output into structured data.
Auto ONU-to-Customer Mapping
Discovered ONUs are matched to subscriber accounts using serial number, MAC address, or port assignment — no manual spreadsheet tracking.
Why This Matters for ISPs
Integrations directly determine how much manual work your team does every day and how quickly you can scale to new markets.
- Regional coverage across 5 countries. Whether you operate in Dhaka, Mumbai, Kathmandu, or Lahore, ISPbills speaks the local payment and SMS language. No more building custom integrations for each market.
- Reduced manual work. Automated SNMP discovery eliminates ONU spreadsheet tracking. Automated payment reconciliation removes bank-statement cross-referencing. Automated SMS delivery replaces one-by-one reminder sending.
- Scalability from startup to enterprise. A 200-subscriber ISP and a 50,000-subscriber operator both need the same integrations — just at different scales. ISPbills handles both without re-architecting your integration layer.
- Vendor flexibility. Broad integration support means you can switch payment gateways, SMS providers, or OLT vendors based on pricing and reliability — without touching your billing workflow.
For detailed configuration guides, visit the ISPbills documentation. Every gateway, SMS provider, and OLT vendor has a dedicated setup walkthrough.
