Food Delivery Script — Multi-Vendor Flutter Source Code

Who buys this food delivery script

This is the system aggregator operators buy when they want to run a Zomato-style platform on Flutter source code they own — not a SaaS subscription that meters them per order. The $5,000 single extended license ships 4 apps (customer, restaurant, driver, admin web), multi-vendor logic, multi-zone routing, a commission engine, and surge pricing. If you are building the platform that hosts many restaurants and takes a cut on every order, this is the SKU. If you only own one restaurant and want to take direct orders, the readymade restaurant app at $1,500 is the right product instead. We have spent the last decade shipping food delivery scripts for operators in India, the Gulf, Southeast Asia, and the US — the codebase has been through real launches, not demo builds.

Multi-vendor SaaS variant — for white-label resellers

The same multi-vendor food delivery app codebase can ship in two configurations. Most operators deploy it once for themselves and run it as their platform. A smaller group of buyers — agencies and product companies — license it and re-sell it as a white-label multi-vendor food app to restaurant chains and regional clients. We support both. The source-code license is the same $5,000 either way; the difference is how you operate it after.

For the SaaS-style resale path, the typical setup adds a tenant layer on top of the multi-vendor logic — one platform binary, many isolated client deployments, each branded separately. That tenant layer is custom work at $25/hr, usually 80 – 120 hours, and it is not part of the base license. If you already know you are building a white-label multi vendor food delivery app product (not a single live aggregator), tell us on the kickoff call so we configure the data model for tenancy from day one rather than retrofitting later.

This absorbs the keyword cluster the old flutter-multirestaurant-saas-app SKU used to own — same buyer, same codebase, one product instead of two overlapping ones.

Multi-zone delivery and dynamic routing

Aggregators live or die on routing. The admin web dashboard ships with a zone editor that draws polygons or radii on a map and binds each zone to its own delivery-fee rules, surge thresholds, and driver pool. Orders are routed by dispatcher logic that checks restaurant location, customer location, available drivers in zone, batch eligibility, and current surge state. We use MongoDB’s 2dsphere geo-index with $geoIntersects for zone lookups — sub-50ms even at city scale. Drivers see only the orders in zones they are signed into, and the surge multiplier is visible in their earnings preview so they self-allocate to where demand is hot. None of this is a bolt-on; it is the spine of the system.

How an aggregator makes $5,000 back fast

Six revenue lines stack in a mature aggregator:

1. Commission per order — 15 – 30% of order value. On a $12 average order at 22% commission, the platform earns $2.64 per order. At 500 orders/day across all restaurants, that is $1,320/day or roughly $40,000/month.
2. Restaurant subscription — $50 – $200/month per restaurant for premium features (analytics, ad budget, priority support). 50 paying restaurants at $100/month is $5,000/month — the license cost paid back monthly.
3. Delivery fee — distance-based, split between platform and driver. Typical platform cut $0.50 – $1.50 per order.
4. Surge pricing — extra $1 – $4 per order during peak hours. On 30% of daily orders, this is meaningful margin.
5. Featured listings and ads — restaurants pay for top placement in search and banners. Highest-margin line; pure software revenue, no driver cost attached.
6. Customer subscription — Eats Pass / Swiggy One / DashPass-style. $4.99 – $9.99/month for free delivery + perks. Drives retention and gives you predictable monthly cash.

A modest aggregator running 500 orders/day in one mid-size city covers the $5,000 license in the first month from commission alone. The other five lines are upside. Honest framing: most aggregators do not hit 500 orders/day in month 1 — recruiting restaurants and acquiring customers takes 60 – 120 days. The unit economics work; the launch ramp is the real cost.

Customisation services — $25/hr

Post-purchase customisation runs at $25/hr or fixed-bid. Typical asks:

• Courier app variants (motorcycle vs car vs walker fleets with different earnings logic)
• New vertical modules (grocery, pharmacy, alcohol, flowers) under the same admin
• Per-country payment + tax setup (PayU for India GST, Square for US sales tax, local Gulf gateways)
• WhatsApp ordering integration
• AI-driven restaurant ranking and personalised feed
• Loyalty programme expansion
• B2B billing layer (invoice mode, NET-30 terms) for catering operators

Most live aggregators we work with come back for 40 – 200 hours of customisation in the first six months. Budget for it. Contact our team with a feature list and we will scope it.
