WordPress E-Commerce & Booking Website for an app to be built around our web-site

I need a compact WordPress App that can both sell services and handle service reservations from day one. WooCommerce (or an equally solid alternative) will power the store, while an integrated plugin-based solution must cover an online calendar, one-off appointment booking, and recurring service subscriptions.

A bright, modern layout is essential—clean lines, easy navigation, and mobile-first responsiveness so visitors instantly feel at ease and can complete a purchase or reservation without friction.

Key points you’ll handle:
• Full e-commerce configuration: products, tax, shipping / delivery or download settings, and secure payment gateway integration.
• Calendar display that syncs availability in real time.
• Booking workflow with automated confirmations, reminders, and the option for customers to manage or reschedule their slots.
• Subscription setup for ongoing services (renewals, upgrades, and cancellations directly in the customer dashboard).
• Performance tuning, SEO-friendly structure, and basic on-page optimisation.
• Brief handover guide so my team can add products or adjust schedules without touching code.

Acceptance criteria: Every checkout and booking path must complete successfully in test mode, display responsive on major devices, and load in under three seconds on standard broadband. Once these boxes are ticked, we’re ready to go live.
