Ready-to-Launch Grocery App Suite

I’m ready to purchase a complete, white-label multi-vendor grocery solution that I can put my branding on and publish to Google Play without a lengthy build cycle. What I need handed over is:

• An Android customer app where shoppers browse multiple stores and pick a preferred delivery time slot during checkout.
• A web (or Android) store panel for each vendor so they can manage inventory, prices, and orders.
• A central admin panel where I control onboarding of new stores, commissions, offers, and overall system settings.

The code must already be production-tested; I’m not looking to fund a new build. After I provide my logo, colors, and basic store data, I should be able to launch the app suite quickly—ideally within a few days.

Key capabilities I’m expecting:
– Multi-vendor catalog with category and search.
– Slot-based delivery scheduling (no “fast delivery only” logic).
– Coupon/discount engine, taxes, and commission management.
– Order tracking and push notifications (Firebase or similar).
– Payment gateway integration that I can swap for my local provider.
– Full source code, documentation, and installation support for app + panels.

If your solution ticks these boxes and you can show a working demo right away, let’s talk so we can close the purchase and start re-branding immediately.
