Sunshine Coast Web Design
Internet Service Provider Website Design
Project Brief
Onenet Broadband needed to move beyond a manual, admin-heavy signup process. The goal was a conversion-focused ISP website that didn’t just generate leads – it needed to function as a complete telecom sales and provisioning pipeline, with WordPress connected directly to Splynx.
The result is a fully automated broadband ordering system purpose-built for Australian ISPs operating across NBN, Opticomm, and private fibre networks.
WordPress ↔ Splynx Integration
The core of the build is a custom WordPress plugin that acts as a true frontend for Splynx – not a disconnected CRM or basic form handler.
Capabilities include:
- Real-time Splynx API communication with structured error handling and logging
- Automated customer account creation directly from checkout
- Tariff ID mapping for accurate plan and add-on assignment
- Recurring and once-off billing synchronisation
- Secure EA token authentication
This effectively turns WordPress into a telecom application layer tightly coupled with backend provisioning.
Broadband Checkout & Provisioning Flow
The checkout was engineered to align frontend UX with real ISP backend requirements:
- Address validation – service qualification against NBN, Opticomm, and fibre availability
- Dynamic plan filtering – available plans filtered by network type and speed eligibility
- Real-time pricing – monthly and once-off costs calculated on the fly
- Stripe pre-authorisation – payment details validated before provisioning begins
- Splynx customer creation – account created instantly via API on checkout completion
- Service provisioning – plans and add-ons assigned using mapped tariff IDs
- Billing activation – structured to align with Splynx billing cycles and automation rules
Key Technical Challenges
Splynx API Constraints – Inconsistent API responses required pre-validation logic and detailed logging to ensure reliable provisioning without silent failures.
Telecom Product Complexity – Multiple plan types, speed tiers, add-ons, and billing models had to be mapped into a structured system Splynx could reliably consume.
Service Eligibility Enforcement – Users are blocked from incompatible plans based on their address and network type, while still seeing the full product range.
Billing vs Provisioning Logic – Shifted the architecture from invoice-first to a service-first provisioning model aligned with how ISPs actually operate in Splynx.
Technical Stack
Custom WordPress ISP plugin · Splynx REST API · Tariff ID mapping system · Stripe PaymentIntent pre-auth · Session-based checkout state management · Carrier-aware eligibility logic (NBN / Opticomm / private fibre) · Inline validation and error handling · Modular plugin architecture
Outcome
The system replaced manual provisioning workflows with a scalable digital pipeline – reducing errors through strict validation, accelerating customer onboarding, and giving Onenet a foundation to scale their product offerings without increasing admin overhead.
