Why your business needs its own mobile app

A business mobile app is a dedicated channel where customers shop, reorder, earn rewards, and get notifications, while partners or employees manage orders and documents. Unlike a website, an app lives on the user's phone and is just one tap away.

It makes sense when you already have loyal customers who buy regularly, or a process that's easier to run from a phone. If shoppers come once from an ad, it's better to invest in an ecommerce store first and put the app on hold.

Business apps we build

Solution icon

Store app

Catalog, search, cart, checkout, shipping, and order history, so repeat customers can reorder in a minute without opening a browser.

Solution icon

Loyalty program

A rewards card on the phone, earning and redeeming points, personalized offers, and promo notifications instead of plastic cards and email blasts.

Solution icon

Dealer app

Wholesale pricing, warehouse stock, quick ordering by SKU, invoices, and documents for partners who order from you regularly.

Solution icon

Team app

A tool for sales reps, couriers, or field technicians: routes, work orders, photo reports, customer signatures, and offline mode.

Solution icon

Services and booking

Online booking, reservations, service calls, or delivery orders with status tracking for businesses that sell services, not products.

How we build a business app

From idea and business process to an app people keep coming back to

circles

We find out who will use the app and why: what they should be able to do faster than on the website, and how that will impact sales or team productivity.

We review your systems (website, CRM, accounting, inventory, payments) and define where the app will pull products, prices, stock, and rewards from.

We choose the approach, native or one codebase for iOS and Android, and agree on the scope of the first version to release in the app stores.

We design screens following Apple and Google guidelines, apply your brand style, and show you a clickable prototype before development starts.

We build the app and backend, connect payments, notifications, and analytics, and test on real phones of different models.

We prepare the store listing and screenshots, take the app through Apple and Google review, and monitor bugs and user feedback after release.

These days it's extremely hard to find marketers and developers under one roof. My task was to find a team that could deliver high-quality SEO and also implement the technical changes that effective SEO requires. We'd run into problems with other SEO companies: they would hand us a spec for website improvements, and then we had to find another team to implement them ourselves. That took a lot of time and slowed down the site's growth. The Promodex team does everything end to end, and that's a huge competitive advantage!

Google
Previously, almost all of our traffic was branded — people who already knew what they were looking for. The goal was to start showing up for category searches, and that's slower work than anyone would like. For the first three months the chart was so flat that I asked twice whether we were wasting our money — in response, they showed me interim metrics instead of just asking me to be patient. From the fourth month, category pages started ranking, and by the sixth month organic revenue had grown 42%. Paid ads now run in parallel, but with a much smaller budget — mainly because we stopped paying for traffic on our own branded keywords.

Promodex has been providing technical support for our online store since March 19, 2024. Over almost 300 hours, they've completed tasks of varying complexity very quickly and reliably — not a single task left "stuck" or unfinished. Communication is clear, response times are fast, and the site runs smoothly. We recommend them as a strong OpenCart support team.

Promodex built our website for Car Textile and handles our SEO. We work across all of Ukraine (wholesale and retail), so it was important to have a proper catalog and for the site to be found on Google. They delivered everything quickly: structure, usability, technical optimization, and advice on keywords and content. The results are noticeable: more relevant inquiries and steady growth in search. Thank you to the team, and we recommend them!

Mobile App Development for Sales and Business Operations

What business app development includes

An app is more than screens on a phone. To work, it needs several components:

  • the iOS and Android app itself, which people install from the App Store and Google Play;
  • a backend that stores users, orders, rewards, and settings;
  • data sync with your website, CRM, accounting system, and warehouse;
  • an admin panel where a manager can update banners, promotions, and notification copy without a developer;
  • analytics that show what people do in the app and where they abandon purchases.

If some of this already exists, such as an ecommerce store with an API, the app can connect to your existing data instead of duplicating the catalog.

Who really needs an app and who doesn't

An app pays off where people come back often. Typical examples: food and grocery delivery, cosmetics and pet supplies bought monthly on repeat, coffee shops and salons with rewards programs, wholesale suppliers with regular dealers.

It makes less sense if purchases happen once every few years (furniture, electronics, real estate) or if your audience is small and irregular. People won't install a separate app for a single purchase. In those cases, it's better to invest in a fast mobile website, and for some tasks a progressive web app that doesn't need to be downloaded from an app store will do the job.

Options: for customers, for partners, for your team

A customer app competes for space on the phone, so it has to be fast and offer real value: rewards, quick reordering, early access to deals. The upside is a direct communication channel without paying for ads. The downside is that you'll need to promote it; it won't build an audience on its own.

An app for dealers and wholesale customers is simpler in design but more complex in logic: custom pricing, credit limits, documents. On the other hand, it's guaranteed to get used, because it saves time on calls and emails.

An employee app isn't published publicly at all. It replaces paper forms, messaging apps, and spreadsheets. Here, reliability and offline mode matter more than flashy animations.

Native development or one codebase for both platforms

For most store or loyalty apps, cross-platform development with Flutter or React Native is enough: one codebase for iOS and Android, lower cost, and easier maintenance. Native development in Swift and Kotlin is needed when the app relies heavily on the camera, background location, external devices such as scanners and payment terminals, or complex animation. We recommend an approach once we understand your goals, not out of habit.

Integrations an app needs to sell

Customers see the same things in the app as on your website: up-to-date prices, stock levels, order status. That's why most of the work usually goes into data sync, not the interface. We most often connect:

  • a CRM or accounting system (Salesforce, HubSpot, QuickBooks) for orders and customers;
  • card payments, Apple Pay, and Google Pay via Stripe or PayPal;
  • UPS, FedEx, USPS, and other carriers with shipping rates and tracking;
  • a push notification service such as Firebase or OneSignal;
  • your rewards system, if it already runs at your point of sale or on your website.

Learn more about connecting systems in our section on integrations and automation.

What to prepare before kickoff

  • A description of who will use the app, in what situations, and which action they'll take most often.
  • Access or documentation for the systems the app needs to sync with: website, CRM, accounting, payments.
  • Brand guidelines, logo, and copy, if you have them.
  • Apple and Google developer accounts registered to your company, so the app belongs to you, not the contractor.

How to tell if the app is working

Download numbers alone don't say much. We recommend tracking how many people return to the app, what share of orders comes through it, how often customers buy again, and how many people turn off notifications. We set up analytics before release so you see the real picture from day one.

For dealer and employee apps, the yardstick is different: how many orders moved from phone calls and messaging apps into the app, how much time managers save on routine tasks, and whether order errors have dropped. We discuss these metrics with you at the start, so there's a baseline to compare against later.

Common mistakes

  • Copying the website into the app. Users won't see the difference and won't have a reason to install it.
  • Cramming everything into the first version. A big launch takes longer to test and breaks more often. It's better to ship the core and add features based on feedback.
  • Sending too many notifications. Users turn them off or delete the app.
  • Forgetting about maintenance. New versions of iOS and Android come out every year, and the app needs to be updated.

What affects cost and timeline

  • Number of user flows: just catalog and ordering, or also loyalty, booking, chat, and a dealer portal.
  • Platforms and approach: one codebase for both platforms or separate native apps.
  • Integrations: whether your systems already have an API for data exchange or one needs to be built.
  • Backend: whether your existing website can be used or a separate one is needed.
  • Design: standard platform components or a custom visual language with animations.

We calculate the cost once the scope of the first version is clear, itemizing screens, integrations, and backend work separately.

FAQ

We already have an ecommerce store. Do we need a separate catalog for the app? No. The app usually pulls products, prices, and orders from the same store or accounting system.

Who publishes the app on the Apple and Google stores? We prepare everything for submission and handle the review process. The app is listed under your developer account.

Can we start with one platform? Yes, but with a cross-platform approach the second platform costs relatively little, so we usually launch on both at once.

What happens to the app after launch? It needs updates for new OS versions, bug fixes, and improvements based on feedback. You can hand this off to us as part of our app support and development services.
