Custom Mobile App Development for Business
We build apps for iOS and Android and publish them to the App Store and Google Play. For a CS-Cart store we connect PowerApp, a ready-made app that is live in 1–3 weeks. An app with its own logic, back end and integrations we build from scratch.

A ready-made app, an app on CS-Cart or custom development from scratch
The format depends on what the business already has: a CS-Cart store, a website on another platform, an accounting system or just an idea. The more is ready, the faster and cheaper the launch.
PowerApp for a CS-Cart store
We connect a ready-made app to your store: catalog, search, cart, checkout, reward points, push and the customer account already work. We brand it, build it for iOS and Android and publish it.
Submitted to the stores in under a week, live in 1–3 weeks including review.
from $790with publishing from $1,390, for Multi-Vendor $2,190, or a subscription from $79 a month
An app with CS-Cart as the back end
If there is no website, or the business runs on spreadsheets and an accounting system, CS-Cart becomes the back end: catalog, orders, payments, shipping, staff roles and an admin panel. Multi-Vendor adds vendor dashboards, commissions and payouts.
A store on another platform, such as WooCommerce, Shopify or your own system, can be connected to PowerApp through the connector.

Custom development from scratch
Services, platforms, dealer and staff portals, apps with maps, bookings and payments. We design the flows and the interface, build the app and the back end, publish and support it.
We build with React Native: one codebase for iOS and Android. The code belongs to you.

Built-in CS-Cart integrations work in the app right away
The app takes its data from CS-Cart: shipping, promotions and reward points set up in the store admin work in the app with no extra development. Payments go through the gateways listed here; we connect others on request.
- PaymentsPayPal, Stripe (including Stripe Connect on Multi-Vendor), Tabby, Tamara, Paymob; cash on delivery and bank transfer
- Shippingreal-time UPS, FedEx, DHL, USPS, Canada Post, Australia Post and Swiss Post rates from CS-Cart; store pickup from your locations on a map; Fodel collection points in the UAE
- Back officeproducts, prices and stock come from CS-Cart and orders go back to it, so an ERP connected to the store serves the app too
- Marketingpromotions, coupons, reward points, reviews and collections from CS-Cart add-ons
- Messagescustomer chat with the store and vendors, order status and return notifications
- Multi-Vendorstorefronts, vendor pages and lists, a Vendor tab: products, orders, stock and balance

Discuss an integrationAn app is also a back end, an admin panel and integrations
Customers only see the screens. Behind them are the catalog and prices, orders and payments, push campaigns and data exchange with your back office. PowerApp has these layers built already, so a launch takes weeks, not months.

What changes when a business gets an app
An app lives on the phone’s home screen and has access to what a browser cannot reach. That is where the difference comes from, both for the business and for the customer.
Almost anything a phone can do, an app can do too
The list is short, but it answers the question “can you build that?”. An app can use almost everything a phone can do, while a browser either has no access to it or only limited access.
We take over an app built by another contractor
First we review the code, builds and store accounts, then propose a plan: what to keep, what to fix and what is easier to move to PowerApp. The rights to the code and accounts stay with you.
GStoreQ8, Kuwait: upgraded the app to the current version while keeping earlier customizations, connected KNET payments and push.
Garage AAC: a complete redesign of the standard CS-Cart mobile app.
An interface review is free. Changes are estimated after the review. Maintenance costs $80, $160 or $320 a month.

How much mobile app development costs
A ready-made app for a CS-Cart online store costs from $790, with App Store and Google Play publishing from $1,390. An app for a Multi-Vendor marketplace is $2,190, with your own logic on top of PowerApp from $7,000. Custom development from scratch starts at $15,000.

Based on the prices above. We give an exact estimate after reviewing the task, free of charge.
Get an estimateFive stages, from analyzing the task to the app stores
At the end of each sprint we hand over a build you can install on your phone. You see the progress itself instead of a report about it.
- We break down the task and business processes, study the niche and how people will use the app.
- We map roles and user scenarios and prototype the key screens.
- The result: a specification and a stage-by-stage estimate.
- We design the interface for the specifics of iOS and Android: they are different platforms with their own rules.
- We work out every state: empty screens, errors, loading, no connection.
- You see the app before the first line of code is written.
- We split the work into sprints, and each one ends with a build you can install on your phone and try.
- The client side in React Native, plus the backend and API.
- Integrations: ERP or accounting system, payment gateway, shipping, analytics.
- We test on real devices: different screens, OS versions, weak connections.
- We prepare descriptions, screenshots and materials for the app stores.
- We publish to Google Play, the App Store and Huawei AppGallery, under our developer accounts or yours, whichever suits you, and see the app through review.
- We monitor crash reports and user reviews and fix what we find.
- We release updates for new iOS and Android versions.
- We add functionality as your business grows.
Tell us about your task: we reply within one business day and suggest a format, timeline and estimate. The review is free.

- Contract and estimateScope and cost are fixed after analysis: first the specification and a stage-by-stage estimate, then development.
- PaymentBy bank transfer against an invoice or by card.
- The code is yoursYou can develop the app further with us, with your own team or with another contractor.
- Store accountsWe publish under our developer accounts or yours, whichever suits you.
React Native: one codebase instead of two
We build with React Native, and the reason is simple math: one codebase runs on both iOS and Android, so the logic does not have to be written and tested twice. One team, one test suite, and every fix ships to both versions of the app at once.
Faster to the first version
Shared logic is written once rather than separately for each platform. Less code means shorter timelines and fewer places where something can break.
Updates without resubmission
Some fixes reach users without going through store review. A bug can be fixed the day it is found, not after a week of waiting for approval.
Native when nothing else will do
Heavy graphics, specialized hardware, rare system features. If your task needs that, we will say so up front and build it natively.

Frequently asked questions about mobile app development
A ready-made app for a CS-Cart online store (PowerApp) costs from $790, with App Store and Google Play publishing from $1,390, for a Multi-Vendor marketplace $2,190, and with your own logic and integrations on top of PowerApp from $7,000. A store on another platform is connected on request. Custom development from scratch, with your own back end, starts at $15,000. Details are in the Pricing section.
PowerApp for a CS-Cart store is submitted to the stores in under a week and live in 1–3 weeks including review. Custom development takes months: the exact timeline and stages are fixed in the estimate after analysis.
Yes. PowerApp gets its data through a connector, and another platform can be connected to it: WooCommerce, Shopify, Magento or your own system with an API. We write an adapter for its API: the connection is quoted on request after we review the API. If there is no API or it is not enough, we will suggest moving the catalog and orders to CS-Cart.
Yes. CS-Cart provides the catalog, prices and stock, orders, payments and shipping, staff roles and an admin panel, and Multi-Vendor adds vendor dashboards, commissions and payouts. The app and the website, if you add one later, run on the same data.
The built-in CS-Cart ones: the app takes its data from the store, so shipping, promotions and reward points set up in the admin work in the app too. Payments: PayPal, Stripe (including Stripe Connect on Multi-Vendor), Tabby, Tamara and Paymob, plus cash on delivery and bank transfer; real-time UPS, FedEx, DHL, USPS, Canada Post, Australia Post and Swiss Post rates; store pickup from your locations on a map; Fodel collection points in the UAE; promotions, coupons and reward points; chat with the store and vendors; Google Analytics and push through Firebase. Anything else we connect on request: KNET, MyFatoorah, Checkout.com, Authorize.Net and other gateways from $300; carrier pickup points on a map, social sign-in or chat from $150; a store on another platform on request.
Most likely not. For stores we have a ready-made app, PowerApp: catalog, cart, payments and push are already built, and launch takes 1–3 weeks. Development from scratch is for cases where a ready-made solution does not fit: services, portals, industry apps with their own logic. See PowerApp
45 of our clients’ apps are live in the App Store and Google Play. They include Potolcom Pro and 30 more wikki.market dealer apps, the Kaufbei.de marketplace in Germany, Stamp Collectors in the USA, Altyn Açar in Ashgabat, SkladEdy in Crimea, the ELIT MARKET medical apparel marketplace, Essenzi, Branded Perfume and French Fragrance in the Gulf countries, YouMarket, iRuZon, Person Express Market and Elite Aqua. Store links are in the Case studies section.
From you we will need:
- business requirements: we will write the specification based on them;
- access to the systems the app will exchange data with;
- Google Play Console and Apple Developer accounts: if you do not have them, we will help you set them up.
On Google Play, the App Store and Huawei AppGallery. We prepare descriptions, screenshots and store materials, take the app through review and respond to the reviewers’ comments. If you do not have developer accounts yet, we will help you set them up.
One, three or six months of support are included in the PowerApp plan. After that, maintenance costs $80, $160 or $320 a month: rebuilds for Apple and Google requirements, certificates and push keys, connector monitoring. Access to PowerApp updates renews for a year at $790, or $1,590 for Multi-Vendor.
The app keeps living: new iOS and Android versions come out, store requirements change, bugs turn up. We monitor crash reports and user reviews, release updates and add functionality. Thanks to React Native, some fixes reach users without going through store review.
You do. The rights to the code we write transfer to the client. That means you are not tied to a contractor: you can develop the app further with us, with your own team or with anyone else.
We work under a contract, and the payment terms are agreed in it. Scope and cost are fixed after the analysis: first the specification and a stage-by-stage estimate, then development.
Whichever suits you. We can publish under our Apple and Google developer accounts or under yours. If you do not have accounts yet, we will help you set them up, and then the app is registered to you from day one.
