Selected projects

Three systems for digital operations.

From affiliate campaigns and orders to the customer experience after purchase.

01 / AFFILIATE MANAGEMENT

Sistem Rezeki Digital

An affiliate platform connecting campaign performance with commission management. Affiliates can track visits, leads and earnings, while admins review payout batches.

Challenge

Affiliate performance and commission payments needed a clear tracking process.

Key features

Affiliate dashboard, direct and referral leads, commission totals, payout batches and reports.

Users

Affiliates promoting campaigns and admins managing payouts.

Outcome

Performance and payouts are visible in one mobile-friendly system.

02 / ORDER MANAGEMENT

Order Management System

A system for managing orders after checkout. Payment status, receipts and orders that need follow-up can be handled in one place.

Challenge

Unfinished orders can be missed when receipt checks and customer follow-ups are handled manually.

Key features

Searchable orders, payment status, follow-up reminders, WhatsApp actions and sales statistics.

Users

Admins checking payments and communicating with customers.

Outcome

Orders requiring action are easier to spot, alongside sales summaries by period.

03 / DIGITAL PRODUCT ACCESS

72-Hour Audio Access System

A private access page for Audio Air Penawar Sufi DIY customers. They listen to the instructions first, then unlock the main audio. The 72-hour access period begins with its first play.

Challenge

Each customer needs clear instructions and a clear audio access window.

Customer flow

Finish the instructions, unlock the main audio and use it within the 72-hour access period.

Access management

Admins can create private customer links and track when access starts and expires.

Outcome

Audio playback and access timing are presented in one easy-to-follow page.

Admin access management
