I’m launching a new site that will sell virtual phone numbers and needs to work exactly like https://www.smsz.net/—only cleaner at first glance. Every public-facing and back-office flow on the reference site must be reproduced: user sign-up, searchable number catalogue, automated cart and checkout, balance top-up, ticketing, and full admin dashboards. Design • Visual style: modern with a light colour palette so pages feel uncluttered yet professional. • The interface should load fast, with intuitive navigation that cuts down the clicks it currently takes on SMSZ to reach a number purchase screen. Key functionality • Reseller / API endpoints are non-negotiable; external partners must be able to query availability, place orders, check balances and pull usage reports programmatically. • All other features visible on the reference site—catalogue search, shopping cart, integrated billing, and so on—need to be mirrored so existing SMSZ users would instantly understand the flow here as well. Deliverables 1. Responsive front end reflecting the modern, light design brief. 2. Fully working back end replicating SMSZ logic, including automated number provisioning and balance management. 3. Secure, documented REST API for resellers. 4. Admin dashboard to oversee users, orders, numbers, finances and support tickets. 5. Deployment instructions and short hand-over session so my team can maintain the platform in-house. Acceptance criteria • All major user journeys from sign-up to successful purchase demoed live. • API endpoints pass sample integration tests for search, order and balance queries. • Page-load scores and basic security checks meet current best-practice benchmarks.
