Instant e-commerce, also called quick commerce or q-commerce, means selling everyday goods online and delivering them within about an hour from stock kept close to the customer. That stock sits in a small store closed to shoppers, often called a dark store, or on the shelves of a local shop. For a store owner in 2026, the main decision is how to sell this way: through a delivery platform such as Uber Eats or DoorDash, or through your own app with a delivery partner behind it.
Online sales keep taking a bigger share. The US Census Bureau puts e-commerce in the second quarter of 2026 at $340.2 billion, 17.1% of all retail sales and 12.2% more than a year earlier (US Census Bureau, quarterly e-commerce report). This guide compares the costs of both routes, lists what your own app needs, names the hard parts, and shows an example run of our estimate.
Platforms bring customers and couriers, and they charge for both. Here are the US list prices on the platforms’ own pages on 30 October 2026.
| Channel | What the store pays |
|---|---|
| Uber Eats Marketplace, Lite plan | 20% of each delivery order (lower in some cities); 7% for pickup |
| Uber Eats Plus and Premium plans | 25% and 30% of each delivery order, after a 30-day 0% start |
| DoorDash Basic, Plus and Premier plans | 15%, 25% and 30% of each delivery order, after a 0% start; 6% for pickup |
| Uber Eats webshop (your own site) | A 2.5% order processing fee plus $0.29 per order |
| Uber Direct (delivery for orders from your own channels) | From $7.99 per delivery |
| Online Ordering by DoorDash (your own site) | No commission; a payment processing fee |

Take a $40 order. On a 25% plan the commission is $10. The same order through Uber’s webshop costs $1.29 in fees, and Uber Direct delivery starts at $7.99, so $9.28 in total. That looks close, but the two routes buy different things. The platform also finds the customer. Your own channel doesn’t, so you pay to reach people yourself.
So the rule of thumb is: use platforms to reach new customers, and your own channel for people who already order from you. Once most orders come from repeat customers, the commission you save on their orders is what pays for your own app.
Your own channel is four pieces of software, not one:
One cost you avoid: app store commission on orders. Apple’s guideline 3.1.3(e) says that if your app sells physical goods or services used outside the app, you must use payment methods other than in-app purchase, such as Apple Pay or card entry (App Review Guidelines). Your payment provider’s fee still applies.
Our guide to mobile commerce for existing businesses covers the wider app-or-web question.
Speed is the promise, and three things break it.
Stock accuracy comes first. Promising 30 minutes for an item that turns out to be gone costs more trust than a slower promise. Sync stock from the till or the warehouse system before you advertise speed.
Delivery zones come second. Draw them by realistic travel time, not by distance, and show the zone check before the customer fills the cart.
The live map is third. Customers want to see the courier, and staff want to see every order. On LEV, a live map app for dog owners on iOS and Android, users see each other in real time, and the map had to show hundreds of items without looking cluttered. We solved it with filtering and clustering. A delivery map has the same problem at peak hours.
Our project estimate turns your brief into user stories, such as “check if my address is in the delivery zone” or “track my courier on a map”. You confirm what is in scope, and every hour in the budget traces back to a story you kept. We check the hours the model suggests against what our team actually books on finished projects, then multiply by our published rate of $39-55 an hour. The unit economics show how many customers pay for the build and in which month it is paid back.
Here is an example run of our estimate’s math with sample inputs: an online store with a mobile app, catalogue, cart, checkout and an orders admin. Every input is an assumption. Only the arithmetic is ours.
| Line | Type | Value |
|---|---|---|
| Budget range for the build | Output | $5,900 to $12,300 |
| Timeline for the build | Output | 5 weeks |
| Spend a month per customer | Assumption | $45 |
| Margin | Assumption | 35% |
| Months a customer keeps buying | Assumption | 10 |
| Cost to win a customer | Assumption | $25 |
| New customers a month | Assumption | 200 |
| Profit a month per customer | Output | $16 |
| Lifetime value of a customer | Output | $160 |
| Left per customer after the cost to win them | Output | $135 |
| Customers who pay for the build ($9,100, the budget midpoint) | Output | 68 |
| First month that earns more than it spends | Output | Month 2 |
| Month the build is paid back | Output | Month 4 |
This sample has no courier app and no dispatch. Instant delivery adds those stories, and the estimate adds their hours to the range. For comparison, our published price for a first version of a mobile app is $5,000-15,000, typically 2-4 weeks plus store review. Across 95 agencies, the median published MVP starting price is $13,234 and the median promised timeline is 6 to 12 weeks (Rocketech MVP Price Index 2026, H2 edition). Those are published prices, not what agencies charge after scoping.
To try it with your own numbers, see what your idea costs to build. It is a planning range, not a fixed quote.
It is online selling of everyday goods, such as groceries, household items or medicines, with delivery within about an hour from stock kept close to the customer. It is also called quick commerce or q-commerce.
In the US in October 2026, Uber Eats lists 20%, 25% or 30% of each delivery order depending on the plan, and 7% for pickup. DoorDash lists 15%, 25% or 30%, and 6% for pickup. Orders through your own site cost much less in fees, but you pay for delivery and for finding customers.
Usually not first. Start on a platform, see how many orders come from repeat customers, then build your own channel for them with a delivery partner’s API. Your own couriers come last.
It depends on the stories you confirm. In an example run of our estimate’s math with sample inputs, a store with a mobile app, catalogue, cart, checkout and orders admin came to $5,900 to $12,300 and 5 weeks, without courier or dispatch work. Across 95 agencies, the median published MVP starting price is $13,234 (Rocketech MVP Price Index 2026, H2).
