Custom Magento POS integration
Appfront builds custom integrations between your Magento webshop and point-of-sale system. Stock, orders, customer data and product information flow automatically between the shop floor and the webshop, so both sales channels always work with the same up-to-date data and your team no longer has to synchronise anything by hand.
Unified commerce: till and webshop as one system
Magento, now part of Adobe Commerce, is one of the most widely used e-commerce platforms in the world. The platform offers extensive REST and GraphQL APIs through which external systems can read and write products, orders, stock and customer data. That makes it particularly well suited to integrations with physical sales channels.
A point-of-sale (POS) integration connects your in-store till system with your Magento webshop. The result: one product catalogue, one stock level, one customer profile, whether the sale takes place online or in the physical shop. Every transaction is sent through straight away, so your accounts, stock management and customer communication always stay consistent.
Appfront builds these integrations to measure, using Magento's official APIs. We tailor the scope, synchronisation direction and error handling to your specific situation, from single-store retailers to multi-branch chains with hundreds of SKUs. See also our wider e-commerce development services.
Bidirectional Synchronisation
Changes in your point-of-sale system or in Magento are passed on to the other system, either immediately or at set intervals. Stock levels, prices and customer data remain consistent without manual work.
One stock level across all channels
No more overselling. A sale in store immediately reduces online stock, and vice versa. Multi-source inventory (MSI) in Magento 2 enables stock management per branch.
A single customer profile
Customers who shop in store and order online get one profile. Purchase history, loyalty points and contact details are available to your team across both channels.
Our development process for Magento POS integrations
A POS integration touches several business-critical processes at once: stock, in-store sales, online orders and customer data. That's why we work step by step, from analysis to go-live, so that every component is tested and validated before it goes into production.
We map out your point-of-sale system, Magento installation and the data flows you need. Which entities must sync? In which direction? How often?
We design the integration architecture: choice of API (REST or GraphQL), authentication method, error handling and conflict resolution for simultaneous updates.
Iterative development with automated tests for each data entity. You receive working builds along the way to check the synchronisation on a staging environment.
Controlled go-live with data validation and a safety net. This is followed by ongoing monitoring, with alerts for synchronisation errors or unexpected discrepancies.
What a Magento POS integration delivers in practice
Every integration is tailored to your sales process and till system. Below are the features we most often build for retailers who want to connect their physical and online channels.
Stock management and synchronisation
Stock levels are updated with every transaction, whether it is an in-store sale or an online order. Magento 2's Multi-Source Inventory (MSI) lets you track stock per branch, so customers can see online which shop has a product in stock.
Unified orders
In-store sales are recorded as orders in Magento, complete with customer details, payment method and product information. Online orders can optionally be sent to the point-of-sale system for in-store collection (BOPIS). One order overview across all channels.
Customer data and loyalty
Customers who pay in store and order online are merged into a single profile in Magento. Purchase history, loyalty points, discount codes and contact details are available across both channels. Your team can run targeted marketing based on the full picture of buying behaviour.
Product catalogue sync
Product information, including titles, prices, images, SKUs, categories and attributes, is synchronised between Magento and the point-of-sale system. Price changes made in Magento appear at the till straight away, and new products only need to be created in one place.
Payment processing
Till transactions are sent to Magento, including payment method and amount. We support integrations with widely used payment service providers such as Adyen, Mollie and PayPal. Returns and refunds are processed in both systems.
Reporting & analytics
All sales data, both online and offline, comes together in Magento. This makes it possible to generate consolidated reports: revenue per channel, bestsellers, customer retention and stock turnover. Optionally, we pass the data on to tools such as Power BI or Google Looker Studio.
Retail sectors that benefit from a POS integration
The value of a Magento POS integration varies by type of retailer. Below are four typical scenarios where we have built experience, each with its own challenges and data requirements.
Fashion & lifestyle retail
Clothing shops with an online channel often struggle with size and colour stock that differs by branch. A Magento POS integration synchronises stock at configurable product level, by size, colour and location. Customers can check online which size is available in which store and, if needed, reserve it for collection.
Specialty food shops & delicatessens
Specialty shops with limited shelf life and a changing range benefit from real-time inventory synchronisation. A product that sells out in store disappears from the webshop immediately. Seasonal offers and batch-specific products are managed centrally in Magento and automatically sent through to the till.
Building materials & technical wholesale
DIY and technical wholesale businesses often work with large product catalogues and customer-specific pricing agreements. A POS integration ensures that over-the-counter sales apply the same tiered prices and customer terms as the webshop. Stock movements from bulk counter sales are processed immediately so that webshop availability stays accurate.
Franchise & multi-store chains
Retail chains with multiple branches benefit from a centralised integration in which each location has its own stock in Magento MSI. Head office manages the product catalogue and pricing; branches scan and sell with their own tills, while all data flows back to one central Magento dashboard.
Technology we use
We build Magento POS integrations with modern, maintainable stacks. The precise choice depends on your till system, hosting environment and internal preferences, so that your team can manage or further develop the integration. We document every integration clearly and are happy to work alongside your existing suppliers.

Security and privacy in POS integrations
A POS integration processes customer data, transaction data and, in some cases, payment information. Appfront treats every integration with that data as a starting point. We do not store payment data outside the certified payment provider, we encrypt sensitive information in transit and at rest, and we document the data flows so your record of processing activities stays up to date.
Authentication with Magento runs via OAuth 1.0a or bearer tokens with limited permissions. We agree in advance which API scopes are actually needed and restrict access to what is strictly necessary. We apply the same principles on the till system side of the integration.
More on our security approach: information security policy and CVD policy.
- GDPR-compliant data processing and data minimisation
- Encryption in transit (TLS 1.2+) and at rest
- PCI DSS-compliant: no storage of payment data
- OAuth 1.0a and bearer tokens with least-privilege scopes
- Audit logs with traceable data flows
- Monitoring and alerting for synchronisation discrepancies
- Secrets management in line with best practice
- Documentation for your record of processing activities
Frequently asked questions about Magento POS integrations
Answers to the questions we are asked most often about connecting till systems to Magento.
A Magento POS integration is a technical link that connects your physical till system to your Magento (Adobe Commerce) webshop. Products, stock levels, customer details and orders are synchronised automatically between the shop and the webshop, so your physical and online sales channels work from the same up-to-date data.
In principle, any till system that offers an API or export functionality. We regularly build integrations with Lightspeed, Zettle (PayPal), Square, Adyen Terminal and various industry-specific till software. Custom till systems can also be integrated, provided a technical interface is available.
With every sale, whether on the shop floor or online, the stock level in Magento is updated directly via the API. This can happen near real-time via webhooks or at a configurable interval. This prevents overselling and ensures customers always see current availability.
The timeframe depends on the till system, the number of data fields that need to be synchronised and the desired direction of the data flows. A basic one-way integration can be operational within a few weeks. A full bidirectional integration covering customer data, stock and orders usually takes longer. After an intake meeting, we provide a realistic plan.
The cost is determined by the complexity of the data flows, the number of systems to be connected, the required synchronisation frequency and the amount of custom business logic. The till system itself also plays a role: some systems offer extensive APIs, while others require workarounds. Ongoing maintenance and monitoring also affect the total investment.
Yes. All integrations are developed in line with the GDPR and security best practices. Customer data and transaction data are encrypted in transit and at rest. We apply data minimisation and document the data flows so your record of processing activities remains complete. Payment data is not stored outside the certified payment provider.
Yes. Adobe Commerce Cloud (formerly Magento Commerce Cloud) offers the same REST and GraphQL APIs as the on-premise version. The integration architecture is almost identical, with the difference that certain server configuration choices are implemented differently. Our integrations work with both variants.
Yes. Appfront regularly takes over existing integrations, even if they were built by another party. We first carry out a code and architecture review, map the current data flows and draw up an improvement plan. We can then optimise, extend or completely rebuild the integration where necessary.
