Project description:
"Hi,

I currently have a POS and inventory system built in Google Studio AI. The app already has all the features I need, but the big limitation is that it does not support real-time syncing between multiple users and it isn’t stable enough for daily operations.

What I need:

My first preference is to keep my existing Studio AI app exactly as it is, but make it cloud-based, multi-user friendly, and real-time synced (so any update, addition, or change instantly reflects across all users).

If this is not possible on Studio AI, then I want the app migrated/rebuilt on AppSmith with a Supabase backend (or another stable, equivalent, or better stack you recommend).

Key features that must be included (same as my current app):

Sales & invoicing (with VAT toggle + custom invoice numbers).

Inventory tracking (multi-batch, FIFO costing, stock adjustments).

Debtors & creditors management.

Reports/dashboards (daily sales, stock levels, profit).

PDF invoice/quotation generation with my branding.

WhatsApp PDF send option.

Barcode generation & scanning.

Returns & credit notes handling.

Role-based access control (admin, cashier, etc.).

Database backup system.

In short:
Keep my app as-is, but make it real-time, multi-user, and cloud-based. If that can’t be achieved on Studio AI, then rebuild it on Supabase + AppSmith (or something better you suggest).

Please confirm if you can assist, your recommended approach, timelines, and cost.

Thanks," (client-provided description)
