Telcoptics Solutions Limited
LiveSmart water vending
Smart water vending platform. Hexing IoT meter integration via the XMLVend protocol, dual-mode billing (prepaid token unlock and postpaid invoice generation on reading deltas), M-Pesa STK and C2B collection with callback idempotency, late fees and automatic suspension on arrears, and a mobile API for field technicians to capture readings and acknowledge commands.
The story
Telcoptics Solutions runs smart water vending: physical Hexing-class meters on the customer side, a billing platform on ours. The system covers both billing modes: prepaid (top up, get a token, meter dispenses until the credit runs out) and postpaid (recurring monthly invoice on reading deltas, automatic suspension if arrears go past the grace window).
The meter integration uses XMLVend over SOAP via a vendor-agnostic command dispatch factory, so adding a new meter vendor is a single adapter class rather than a rewrite. M-Pesa STK plus C2B handles payments with callback idempotency; SMS reminders fire at D-3, D-1, and D+3 with auto-suspension afterwards. Three years of production transactions sit in the database.
What we built
Concrete features that are in production today. No roadmap items.
Hexing IoT meters
Smart water meters integrated via the XMLVend SOAP protocol. Meter commands dispatch and acknowledge bidirectionally.
Vendor abstraction
Factory pattern over meter vendors (XMLVend, Liaison STS). Adding a new vendor is one adapter class.
Dual-mode billing
Prepaid (token unlock on payment) and postpaid (recurring invoice on reading deltas) in the same platform.
Daily billing cycle
Recurring invoice generation based on per-customer billing day. Configurable due dates, late fees, auto-suspension.
Reminder cadence
SMS reminders at D-3, D-1, D+3 from due date. Payment confirmations and overdue notices automatic.
Technician mobile API
Field technicians capture meter readings and acknowledge command success/failure from the customer site.
