Mobile commerce apps

Your best customers deserve an app.

Mobile websites work well for first-time visitors. Loyal customers expect more: saved addresses, one-tap checkout, order tracking and offers that reach them by push notification. A dedicated e-commerce app gives you a direct channel to the people who already like your brand.

We build shopping apps that connect to your existing store backend, so products, prices and inventory stay in sync. Checkout supports the payment methods your customers actually use, from Apple Pay and cards to UPI, mada and buy-now-pay-later options such as Tabby and Tamara.

Client testimonials

What our clients say about us.

"What impressed us most about UD3 Logic was their ability to understand the healthcare industry rather than treating the project like a standard software development assignment. They invested time in learning how our hospital operates, the challenges faced by our staff, and the expectations of our patients before proposing solutions. This resulted in a platform that felt practical and intuitive instead of being overloaded with unnecessary features.

Another standout quality was their willingness to collaborate. They welcomed feedback throughout the project, refined features based on our evolving requirements, and consistently focused on finding the best long-term solution instead of the quickest fix. Their technical expertise, combined with clear communication and genuine commitment to our success, made the entire engagement feel like a true partnership.

Even after the primary development work was completed, they continued to provide valuable support and enhancements, which gave us confidence that the solution would continue to evolve alongside our organization."

Ask a question
WhatsApp +91 98874 87026
Q1Do I need an app if I already have an online store?

If you have repeat customers, an app usually pays off. It offers faster checkout, saved details, push notifications and loyalty features that are hard to match on a mobile website. Many brands keep their website for new customers and use the app for loyal ones.

Q2Can the app connect to my Shopify or WooCommerce store?

Yes. We connect the app to Shopify's Storefront API, WooCommerce's REST API or Magento's APIs, so products, stock, prices and orders stay in sync with your existing store and admin.

Q3Which payment methods can you integrate?

We integrate the payment methods your customers use, including:

  • Cards, Apple Pay and Google Pay
  • UPI, Razorpay and Paytm in India
  • mada, STC Pay, Tabby and Tamara in the Gulf
  • E-wallets such as GoPay and OVO in Indonesia
  • Cash on delivery where needed
Q4Can you build a multi-vendor marketplace app?

Yes. We build buyer, seller and admin apps with seller onboarding, product approval, commission rules, payouts, reviews and dispute management.

Q5How do push notifications increase sales?

Push notifications bring customers back with timely, personal messages such as abandoned-cart reminders, back-in-stock alerts, price drops and order updates. We set them up with segmentation so customers only get relevant messages.

Q6Is the app secure for payments?

Yes. Card data is handled by certified payment gateways using tokenisation, so it never touches your servers. We add secure login, encrypted storage and fraud checks to protect customers.

Q7Can the app support Arabic and multiple currencies?

Yes. We build multi-language apps with full RTL layouts for Arabic, and support multiple currencies, tax rules and shipping zones.

Q8How long does an e-commerce app take?

An app for an existing store usually takes 8โ€“12 weeks. A custom commerce app takes about 3โ€“5 months, and a full marketplace 5โ€“7 months or more.

Q9Can the app sync with my ERP or POS?

Yes. We integrate with ERPs and POS systems such as Odoo, SAP, Zoho and custom systems to keep stock, prices and orders in sync.

Q10How do you handle high traffic during sales?

We use auto-scaling cloud hosting, caching, queues and load testing before big sales events.

Q11Can you add buy now, pay later options?

Yes. We integrate Tabby, Tamara, Klarna, Afterpay and similar providers depending on your markets.

Q12Can you build a grocery or quick commerce app?

Yes. We build customer, picker and rider apps with store-level stock, delivery slots or instant delivery and live tracking.
