A practical LPG operations platform to manage coffeeshops, stalls, meter readings, cylinder deliveries, stock replenishment, invoices, receipts, SOA and access rights in one controlled workflow.
Hock Soon Heng’s LPG operation has multiple customer types, different billing terms, stall-level rates, coffeeshop commissions and delivery workflows. The proposed system is designed to reduce manual billing mistakes and give each team only the screens they need.
Meter and cylinder billing can be calculated from recorded readings, delivery records, customer rates and payment terms.
Delivery and meter-reading users can work from phone screens with simplified actions and mobile printer-friendly documents.
Management can review shops, stalls, contracts, invoices, SOA, stock and commission summaries in one place.
The app will follow the actual operating sequence, starting from business setup and contract approval before daily operations begin.
Create coffeeshop locations, commission rates and grouped stall structure.
Prepare customer contract details including rate, billing term, stall, meter, deposit and start date.
Approved contracts become active customers or stalls for billing and operations.
Record meter readings, cylinder delivery, replenishment and stock movement.
Generate invoices, receipts, delivery tickets, delivery orders and SOA.
Track outstanding balances, payment records, coffeeshop usage and commissions.
The V1 launch focuses on the core workflows needed to run Hock Soon Heng’s LPG billing operation with simple screens for non-technical users.
Role-based screens for delivery man, AR, operations and management.
Manage coffeeshops, grouped stalls, stall owners, food type, rates, meters and commission percentage.
Create contract, generate contract document, approve or reject, and onboard approved customers.
Record new readings by QR/customer lookup, calculate usage by m3 and generate meter bills.
Create delivery records, cylinder charges, delivery ticket and invoice or receipt when required.
Track cylinder replenishment and basic stock movements for operational control.
Issue customer documents and view statement of account with payment status.
Print-friendly layouts for desktop and compact delivery documents suitable for mobile printing workflows.
The delivery is phased to get daily operations usable first, then strengthen billing, controls and reporting.
Confirm customer types, rates, billing terms, document formats and approval workflow.
Shops, contracts, stalls, meter reading, cylinder delivery and access rights.
Invoices, receipts, SOA, delivery orders, mobile print layouts and commission summaries.
Data setup, user testing, training, corrections and first billing-cycle support.
The recommended approach uses the BREP method: Base Build, Recurring Support, Enhancements and Professional Services. A 19% development fee is applied to the base build to cover solution design, project coordination, testing and implementation risk.
The Hock Soon Heng V1 launch covers operational setup, contract onboarding, meter billing, cylinder delivery, documents, SOA, access control and mobile-friendly usage.
