Custom e-commerce web applications
We build storefronts, customer accounts, carts, checkout flows and administration screens around the rules of the business.
Web application developmentE-Commerce Development & Integration
E-commerce software
built around your operation.
We do not sell off-the-shelf e-commerce packages. We develop web storefronts, mobile applications, backend services and operations panels for your needs, and connect them to the store, marketplace, ERP, CRM, payment and shipping systems you already use.
A working platform does not have to be replaced. We can build the missing application or integration around it.
What we develop
The storefront is only one part of the system.
We plan customer-facing applications, internal operations and the data connections between them as one product. The scope may be a new build or a focused extension to the platform already in use.
Mobile commerce applications
We develop mobile shopping applications that use the same product, customer and order records as the web channel.
Mobile application developmentBackend and API layers
We design the services that connect storefronts, mobile apps, management panels and external systems without putting integration logic in the user interface.
Order and operations panels
We build role-based screens for order review, fulfilment, payment status, shipment, cancellation, return and exception handling.
B2B, dealer and subscription systems
Dealer groups, customer-specific prices, bulk orders, recurring plans and access rules can be handled as part of the sales workflow.
PrestaShop development
We extend existing PrestaShop stores with custom modules, mobile APIs and product, payment or order integrations where the standard setup is not enough.
View our PrestaShop workE-commerce integrations
We connect the systems behind commerce.
An integration is not complete when the first record moves. Authentication, mappings, failures, retries and daily operational visibility must keep working after launch.
Marketplace and product feed integrations
We prepare and maintain product, variant, price, stock, image and link data for Akakçe, Cimri, Google Shopping and verified marketplace workflows.
Order, price and stock integration
We identify the system that owns each record, then exchange updates through APIs, events or scheduled feeds. Failed transfers remain visible for review and retry.
ERP, CRM and Dynamics 365
When the existing business system provides suitable access, selected customer, product, price and order data can be connected to the commerce application through a controlled backend.
Payment systems
We connect checkout, payment notifications, order status, cancellation and refund steps to the selected provider. Our verified work includes an Octet B2B payment integration.
Shipping and delivery
Shipment creation, tracking codes, delivery status and return records can be connected to the order flow. A separate courier application can be planned when the operation also manages the last mile.

Architecture
How do we structure an e-commerce system?
The exact architecture depends on the current systems and sales model. This flow shows the decisions that usually need to be made.
We identify where each record belongs.
The store, ERP, CRM, product system or warehouse may own different parts of the data. The design starts by making that ownership explicit.
APIs and feeds carry controlled updates.
Authentication, field mapping, validation, logging and retry rules stay in the backend rather than being scattered across user interfaces.
Product, stock and order states stay consistent.
Catalogue, price, stock, cart, payment and fulfilment rules are handled together so one channel does not contradict another.
Each interface is designed for its own job.
The web store, mobile app, marketplace connection and operations panel use agreed records while presenting workflows suited to their users.
Choosing the right approach
Off-the-shelf platform or custom software?
The answer depends on operational complexity, not on a preference for one technology.
For a familiar catalogue and sales flow
Businesses with standard products, pricing, checkout and fulfilment can often launch faster and more economically with an established commerce platform.
When the operation does not fit the standard flow
- Customer or dealer-specific pricing
- Multiple stock sources and warehouses
- Special order, approval or fulfilment steps
- Dedicated mobile application
- Extensive ERP, CRM or marketplace data exchange
Mobile commerce
We do not squeeze the website into a mobile screen.
A commerce app can use the same product, customer, cart and order records as the web store through a controlled backend. Navigation, checkout, notifications and device-specific interactions are then designed for mobile use.
Review our mobile application development serviceSpecial sales models
Beyond a standard shopping cart
B2B, dealer, subscription and digital-product flows need different rules for pricing, access, payment and delivery.
B2B and dealer sales
Customer groups, dealer levels, role-based product access, negotiated prices, quotations and bulk orders can be modelled separately from a consumer checkout.
Subscriptions and digital delivery
Plans, renewals, payment status and access rights need a lifecycle of their own. Files or digital content can be assigned to the customer account after payment.
Extending an existing platform
A working store does not always need to be replaced. We can add the missing API, mobile application, operations screen or integration around the current platform.
Why Rast Mobile?
Experience measured by the problems we have worked on
We do not attach unrelated customer or download figures to our e-commerce work. The relevant proof is the range of commerce models, integrations and application layers represented in completed work.
Experience across different commerce models
Our verified work covers B2C and B2B sales, dealer structures, subscriptions, digital delivery, book sales and PrestaShop-based development.
Integration is part of the product
We consider field mapping, failures, retries and operational visibility alongside the customer-facing experience.
Web, mobile and backend together
One team can design the customer channels, administration screens and the APIs that keep them connected.
Respect for the current operation
We first review the systems and processes already in use. We recommend replacement only when there is a clear reason.
For the broader operational context, review our retail and e-commerce industry experience.
Common questions
E-commerce software development and integration
Yes. We can develop the storefront, mobile application, backend, administration screens and integrations around your catalogue, pricing, order and fulfilment rules. We define the scope after reviewing the users, sales model and existing systems.
Yes, when the existing platform provides suitable APIs, feeds or database access. We first identify which system owns product, stock, customer and order records, then design the missing connection without forcing a full platform replacement.
Yes, if the business system offers a suitable and secure integration method. Selected customer, product, price, stock and order data can be exchanged through a backend layer. We also build applications on Microsoft Dynamics 365 and Dataverse.
Yes. Our verified work includes Akakçe, Cimri, Google Shopping and Entegra integrations. We define a primary stock source and exchange product, price, stock and order updates through APIs, events or scheduled feeds, depending on the systems involved.
Yes. We develop mobile commerce applications that connect to the same product, customer, cart and order records as the web store through a controlled API. The mobile experience is designed for the device rather than copied directly from the website.
An off-the-shelf platform is often the right and economical choice for a standard catalogue and sales flow. Custom development becomes more relevant when the business needs customer-specific pricing, dealer structures, multiple stock sources, unusual order workflows, a dedicated mobile application or extensive ERP and CRM integration.
Yes. Our existing work includes a PrestaShop store connected to a Flutter application through a mobile API, as well as dealer structures with group-specific prices, campaigns and order flows. We review the current setup before deciding whether to extend it or build a separate component.
