How to start
Tell us what you need in your own words. You talk to the developers who would build it and get a written, line-item estimate.
Get a project estimateRunning a local aggregator is an operations business
On a multi-vendor platform you answer for orders you did not cook or pack. When a vendor is slow, an item is missing or a payout looks wrong, both the customer and the vendor come to you.
So our multi-vendor delivery app development puts as much effort into vendor tools and money flows as into the customer app: onboarding without back-and-forth, vendor controls for timings and stock, settlement statements that explain every deduction, and clear refund-liability rules for when things go wrong.
Challenges
Problems aggregator platforms have to solve
Vendors with uneven tech skills
Some vendors run a POS, others a single phone; the vendor app must suit both.
Fair, useful ranking
Listing order affects vendor sales, so it needs clear rules on distance, ratings and sponsored slots.
Settlement disputes
Commissions, discounts, refunds and tax deductions must reconcile per order, or vendor trust erodes.
Different prep times, one fleet
Dispatch must juggle a bakery that packs instantly and a restaurant that needs twenty minutes.

How it works
How one aggregator order moves between customer, vendor and partner
You answer for orders you did not cook or pack, so every hand-off is timed, recorded and settled per order.
- Customer app
Step 1: Customer picks a vendor
Nearby restaurants, bakeries and shops are listed by distance, rating and opening hours, with sponsored places clearly labelled.
- Vendor app
Step 2: Vendor accepts with a prep time
The vendor confirms the order, says how long it needs and marks it ready once packed.
- Dispatch engine
Step 3: Dispatch times the pickup
A delivery partner is offered the job to arrive at the ready time; orders from two vendors get a multi-pickup route.
- Delivery partner app
Step 4: Pickup, tracking and drop
The partner collects from each vendor, calls stay masked, and the customer tracks the delivery live.
- Settlement ledger
Step 5: The order is split for settlement
Item value, discounts, commission, delivery fee and tax deductions are recorded against the vendor for this order.
- Finance team
Step 6: Vendor gets paid, line by line
Each cycle, payouts go out with an order-level statement, and disputes follow a written refund-liability workflow.

Plain-English glossary
Aggregator terms, in plain English
- FSSAI licence
- The food business registration or licence issued by the Food Safety and Standards Authority of India. Food vendors upload it at onboarding, and the platform tracks its expiry and can pause vendors whose licence lapses.
- Vendor-funded discount
- An offer paid for by the vendor rather than the platform, such as 20% off at one restaurant. The ledger must record who funded each discount, or settlements will not match what vendors expect.
- Settlement cycle
- The period, often a week, after which each vendor’s orders are totalled and paid, net of commission, refunds and deductions. Shorter cycles help small vendors’ cash flow but mean more reconciliation runs.
- Refund liability
- The agreed rule for who bears the cost when an order goes wrong: the vendor for a missing item, the platform for a late delivery, and so on. Written down and built into the dispute workflow, it avoids arguments later.
- Sponsored listing
- A paid placement that moves a vendor higher in the app. Clearly labelled and limited in number, it earns revenue without making organic results useless to customers.
Product preview
Screens for customers, vendors and your finance team
Illustrative screens, using a local food, grocery and pharmacy aggregator in Kolkata as the example.
Customer app. Shoppers compare vendors by category, distance and delivery time, with sponsored listings clearly labelled and closed vendors marked. 
Vendor app. Vendors accept orders, set prep times and mark them ready from a phone or tablet, and switch items or the whole store off in one tap. 
Vendor app. Each vendor gets an order-level statement showing item value, their own offers, commission and deductions, so the payout can be checked line by line. 
Admin dashboard. Your team reviews new vendors with FSSAI, GSTIN and bank checks already run, and sets commission and zone before they go live.

Estimating a multi-vendor delivery platform
Number of categories
Food, grocery and pharmacy each bring their own catalogue model and checks.
Cart model
Multi-vendor carts need split orders, multi-pickup dispatch and partial cancellations.
Commission and settlement rules
Category rates, vendor-funded offers, penalties and tax deductions add ledger logic.
Ranking and ads
Sponsored listings and ranking controls add a small ads system to build and govern.
Launch footprint
One city and zone is a far smaller build than multi-city operations from day one.
Estimates are written from your scope, with the effort and assumptions behind each line item.

FAQ
Frequently asked questions
Should customers be able to order from several vendors in one cart?
It is convenient but adds real complexity: one payment split across vendors, separate prep times, a partner collecting from two or more places, and partial cancellations when one vendor declines. We usually recommend launching with single-vendor carts and adding multi-vendor carts later for categories where it clearly helps, such as grocery plus bakery in the same area.
How do commissions and vendor payouts work?
Each order records item value, vendor-funded and platform-funded discounts, your commission, the delivery fee and applicable tax deductions. Each settlement cycle, the platform totals these per vendor, adjusts for refunds and penalties, and pays out through split settlements or a payouts API. Vendors see an order-level statement, which heads off many disputes before they start.
Can we start with restaurants and add grocery or pharmacy later?
Yes, if the data model is designed for it. We keep vendor, catalogue and order models general enough for menus with add-ons, weighed grocery items and prescription-gated products, and switch features on per category. Adding pharmacy later still needs its own verification workflow and regulatory review, but not a rebuild of the platform.
How should vendors be ranked in the app?
Rank by what helps customers first: availability, distance or delivery time, ratings and recent reliability such as acceptance and cancellation rates. Sponsored placements can sit on top, but they should be labelled and limited so organic results stay useful. We make the weights configurable and log ranking changes, so you can explain listing decisions to vendors.
