I run a retail business and my entire online presence sits on a Wix website. I now need a purpose-built web app, embedded directly in that site, that brings three workstreams together: product sales, appointment scheduling, and automated customer emails. Sales module The store already operates on Wix, so the new component must plug into my existing catalog and support full inventory management in real time. While inventory is the immediate priority, I would like the code structured so payment processing and customer reviews can be added later without a rewrite. Appointment scheduling Alongside product sales I offer in-store consultations. The same app should let customers pick a time slot, see live availability, and receive confirmations and reminders generated by the email engine below. Email automation Each purchase or booking should trigger the right email—confirmation, reminder, follow-up, or abandoned-cart nudge—using my current Wix-connected mail service. Templates and key wording will come from me; I need you to wire up the logic and variables so everything sends flawlessly. Core requirements • Built to live inside Wix (Velo, Corvid, or other approved Wix dev tools) • Single unified dashboard for inventory, bookings, and email rules • Mobile-responsive front end that feels native to my site theme • Clean, well-commented code handed over on completion, plus a short loom or PDF walkthrough so I can maintain basic edits myself • Final deliverable fully tested on desktop and mobile with no broken flows or email misfires If you have solid experience with Wix’s dev environment and can point me to a few working examples, let’s talk.
