eCommerce POS integration: how to integrate POS with your website

The ability to reach a global audience, offer products 24/7, and cater to the ever-changing demands of tech-savvy customers has reshaped eCommerce development services.

However, as online sales continue to surge, many businesses find themselves grappling with the challenge of managing both their brick-and-mortar stores and digital storefronts efficiently.

This is where the revolution of POS integration with eCommerce comes into play. 

By combining the power of your Point of Sale (POS) system with your website, you can unlock a world of opportunities and bridge the gap between your physical and virtual retail businesses.

To put things into perspective, the global Point of Sale (PoS) market is projected to grow from $29.02 Billion in 2023 to $81.15 billion by 2030, with a CAGR of 15.8% during the forecast. This represents the amount of businesses using POS systems for their online stores.

In this guide, we'll explore what POS integration truly means, why it has become an indispensable aspect of modern retail, and how you can seamlessly implement this integration to take your business to new heights. 

Are you ready to revolutionize your retail game? 

Let's get started!

‍

What is a POS eCommerce integration? 

Have you ever wondered how shopping online on H&M automatically updates their stock, let's you pay online directly, processes your information and payment, and sends out packaging details all at once? 

That's POS right there.

POS integration with eCommerce refers to the process of seamlessly connecting a brick-and-mortar store's Point of Sale system with its online eCommerce platform. 

It creates a harmonious link between the two distinct sales channels, allowing them to function as one cohesive entity. By bridging the gap between the physical and virtual realms, businesses can synchronize vital data, processes, and functionalities, unlocking a multitude of advantages.

At its core, a POS system streamlines the management of inventory, sales, and customer data between the in-store and online environments. When a sale is made at the physical store, the inventory levels on the eCommerce platform automatically update in real-time, and vice versa.

‍

Why integrate eCommerce platforms and POS?

If you're not already hooked into why a POS is essential even before you select your perfect eCommerce solution, let's explore all the reasons why POS is a game-changer in detail and why you must integrate it to your eCommerce app or websites:

‍

Real-time inventory management 

Integrating eCommerce platforms and POS systems enables businesses to achieve real-time inventory management. This means that whenever a sale is made in-store or online, the inventory levels are automatically updated across all sales channels. 

With accurate and up-to-date inventory data, businesses can avoid the pitfalls of stockouts and overselling. Real-time inventory management also streamlines the supply chain, allowing businesses to efficiently manage their stock levels and allocate resources more effectively.

‍

Unified sales data 

By leveraging eCommerce integration with POS, businesses gain access to a unified pool of sales data. This comprehensive view of sales information provides valuable insights into customer behavior, popular products, and peak buying periods. 

Having a holistic understanding of sales performance across all channels allows businesses to make data-driven decisions, optimize marketing strategies, and identify new revenue opportunities. 

Unified sales data also simplifies financial reporting and streamlines business analysis, giving retailers a clearer picture of their overall performance.

‍

Enhanced customer experience 

Customers today expect a seamless shopping experience, whether they are making purchases in-store or online. 

Integrating eCommerce platforms with POS systems enables businesses to provide just that – a consistent and personalized shopping journey. For instance, customers can easily check product availability online and then visit the physical store to make a purchase. Alternatively, they can place an order online and opt to pick it up in-store (BOPIS).

‍

Efficient order fulfillment 

Integrating eCommerce platforms and POS systems streamlines order fulfillment processes, contributing to faster and more efficient delivery times. With real-time inventory updates, businesses can ensure that orders are fulfilled from the most appropriate location, reducing shipping times and costs. 

Moreover, the integration facilitates accurate order tracking, allowing customers to stay informed about the status of their purchases. Efficient order fulfillment is a crucial aspect of customer service, and a well-executed integration can significantly improve the overall shopping experience.

‍

Benefits of an POS eCommerce integration  

No, we're not done yet.

The reasons above are all the features your eCommerce platforms desperately need, but all of that comes with specific benefits. They must be clear if you look closely enough, but let's delve into the key advantages of POS systems more:

‍

1. Inventory accuracy 

Accurate inventory management is critical for any retail business. The level of accuracy POS provides, empowers businesses to maintain optimal stock levels, reduce carrying costs, and minimize the risk of inventory-related losses. As a result, businesses can focus on meeting customer demands without the worries of stock discrepancies.

‍

2. Time and cost savings 

POS and eCommerce integration streamlines numerous manual processes, saving businesses both time and money. 

By eliminating the need for manual data entry and reconciliation between the physical store and online store, employees can devote their time to more value-added tasks. The seamless flow of information between systems reduces the risk of human errors, further enhancing operational efficiency.

‍

3. Enhanced reporting and analytics 

The combination of POS and eCommerce data provides businesses with a comprehensive view of sales performance and customer behavior. A unified pool of data and a data-driven approach allows businesses to tailor their marketing strategies, identify new revenue opportunities, and continuously improve their offerings.

‍

4. Omnichannel experience 

Omnichannel is the only way to go in this era. 

POS systems help establish an omnichannel experience, where customers can effortlessly switch between in-store, online shopping, and other digital touchpoints with consistency.

Advance integration also enables convenient options such as "buy online, pick up in-store" (BOPIS), "return in-store for online purchases," payment methods, social sharing, and more, enhancing customer convenience, engagement, and loyalty.

‍

5. Improved customer satisfaction 

A seamless shopping experience leads to higher customer satisfaction levels. POS integrations ensure that customers encounter a consistent shopping journey, regardless of the channel they engage with in a unified space.

In the end, every business is about customers. Satisfied customers are more likely to become repeat buyers, recommend the brand to others, and foster long-term loyalty.

How to integrate POS with website: 5 steps  

Whether you're building an eCommerce website from scratch or going for mobile app development services, you'll need a proper guideline for a POS system with eCommerce integration. It's nothing too complex or time-consuming, but you definitely need a good approach that results in an effective and informed choice.

Here's a 5-step method to validate your POS integrations suggested from our experts: 

Step 1: Search your options  

The first and most critical step in the integration process is doing your part of the research in selecting  the right POS system for your business. Consider factors such as the size of your business, your industry, and the specific features you require. (Keep reading for more tips on this step below)

‍

Tips from our experts:

• List and reach out to POS system providers in your niche and ask for demonstrations or free trials. This will allow you to experience the interface and features firsthand and make an informed decision.

• Create a list of essential features you need in a POS system, such as real-time inventory management, sales reporting, and support for multiple payment methods. Use this list as a reference when evaluating different options.

• If you run a small boutique with limited products, a cloud-based POS system like Vend or Square may be an excellent fit. On the other hand, a larger retail chain may benefit from a more robust solution like Lightspeed or Shopify POS.

Step 2: Assess eCommerce platform compatibility 

Once you've decided on a few options after research there's another crucial step.

Before proceeding with the integration, ensure that your chosen POS system is compatible with your eCommerce platform. Many popular eCommerce platforms offer plugins or built-in support for specific POS systems, simplifying the integration process.

In case you don't find any existing solutions, don't panic!

There's times when a custom POS solution is the best option for your business. 

Read on to find out why and when you'll need a custom solution, or consult the experts at COAX Software to help you figure it out! 

‍

Tips from our experts:

• Consult industry experts, your POS system provider and eCommerce platform provider to verify compatibility and explore any available integration options.

• Make sure you check customer reviews and testimonials to see if other businesses in your industry have successfully integrated the same POS system with your chosen platform.

• For example, if you are using Shopify as your eCommerce platform, you can easily integrate it with popular POS systems like Shopify POS or Square to create a seamless omnichannel experience for your customers.

Step 3: Implement the integration 

Once you have selected a compatible POS system and eCommerce platform, it's time to implement the integration. Depending on your chosen systems, this step may involve using APIs, plugins, or middleware to establish the connection.

If you are not tech-savvy, consider seeking professional assistance or consulting with your POS or eCommerce platform provider's support team to ensure a smooth implementation.

‍

Tips from our experts:

• Back up your data before starting the integration process to prevent any data loss or disruption to your business operations.

• Opt for native APIs and plugins with your storefront provider. 

• For example, WooCommerce users have various plugins available, such as Square for WooCommerce or Lightspeed POS integration, which simplify the integration process and ensure a seamless connection between the systems.

Step 4: Test and troubleshoot 

This is a crucial step that may cost you a lot if missed.

After completing the integration, thoroughly test the connection to ensure that inventory, sales, and customer data are syncing accurately between the systems. Be prepared to reach out to the customer service, troubleshoot and address any issues that may arise during this phase.

‍

Tips from our experts:

• Conduct regular data checks and monitor the integration's performance to catch any discrepancies early and address them promptly.

• Create a test environment where you can simulate transactions and evaluate the integration's functionality without affecting live data.

• Suppose you notice discrepancies in inventory levels between your physical store and online shop during testing. In that case, it's essential to investigate and resolve the issue before going live to avoid potential inventory-related problems. 

• During this time, it's necessary to log any communication and data exchange between the POS and the app to make it possible to track any data losses or data corruption.

Step 5: Train staff and monitor performance 

This is an often overlooked aspect of implementing new APIs or features. 

Once the integration is successfully implemented and tested, it's crucial to train your staff to use the integrated system effectively. Provide them with the necessary resources and support to navigate the new interface confidently.

Remember that your software is only as good as your employees know to use it.

‍

Tips from our experts:

• Offer ongoing training and refresher sessions to keep your staff up-to-date with any system updates or changes.

• Monitor key performance metrics after the integration to assess its impact on your business. Track inventory accuracy, order fulfillment times, and customer feedback to gauge the integration's effectiveness.

How to choose a POS system?  

As we said, selecting the right Point of Sale (POS) system is as critical and foremost a decision as choosing a retail software development company. Both can significantly impact the efficiency and success of your ongoing business..

With a myriad of options available in the market, it's essential to consider several key factors before making your choice. Here are the crucial aspects to evaluate when choosing a suitable eCommerce and POS integration:

1. Features 

One of the primary considerations when choosing a POS system is the range of features it offers. Different businesses have distinct needs, so identify the specific functionalities that align with your requirements. 

Look for features such as real-time inventory management, sales reporting, customer management, employee management, and support for multiple payment methods. A feature-rich POS system can streamline your operations and enhance the overall customer experience. Additionally, consider integrating a group buy platform feature to facilitate group purchasing and boost sales through collective buying power.

Tip: Prioritize the features that directly address your pain points and support your business goals. Avoid investing in unnecessary bells and whistles that may complicate the system and inflate costs.

‍

2. Scalability 

As your business grows, your POS system should be able to accommodate your expanding needs. Scalability is a crucial factor to consider, especially if you plan to open new locations or expand your product offerings. 

A scalable POS system will save you the hassle of migrating to a new system in the future and can adapt to your business's changing demands seamlessly.

Tip: Look for a POS system that can handle an increase in transaction volume, inventory size, and the number of users without compromising on performance.

‍

3. Customer support 

You'll need a great amount of support when making decisions, testing, analyzing, and setting up your POS software. Which is why, reliable customer support is vital when it comes to a mission-critical system like a POS. 

Inevitably, you may encounter technical issues or have questions during the implementation or daily use of the system. A POS provider with responsive and knowledgeable customer support can provide timely assistance, ensuring minimal disruption to your business operations.

‍Tip: Reach out to the POS system provider's support team in advance and gauge their responsiveness and willingness to address your inquiries. Also, look for POS providers that offer multiple support channels, such as phone, email, and most importantly live chat, to connect instantly.

When to opt for a custom POS system eCommerce integration? 

Opting for a custom POS system integration becomes a compelling choice for businesses facing unique and specific requirements that cannot be adequately addressed by off-the-shelf solutions. 

While many businesses can benefit from popular pre-built POS systems listed above, custom integrations are worth considering in the following scenarios:

‍

1. Complex Business Processes

If your business operations involve intricate workflows or specialized processes that are not easily accommodated by standard POS systems, a custom integration can be the solution. Customization allows you to tailor the integration to fit your exact needs, ensuring a seamless flow of data between your POS system and eCommerce platform.

Brand spotlight: Starbucks implemented a custom POS system to handle their never-ending complex order customization and inventory management processes. Their system allows baristas to easily customize drink orders while maintaining real-time inventory tracking to optimize stock levels. (Also, it's on brand)

‍

2. Niche Industry Requirements 

Some industries have highly specialized needs that generic POS systems may not adequately address. For example, healthcare software development, and businesses in automotive or manufacturing may require specific inventory tracking, compliance, or regulatory features. A custom POS integration can be designed to meet these unique industry demands.

Brand spotlight: Vetsource, an online pharmacy serving the veterinary industry, opted for a custom POS tailored to meet the unique requirements of their niche. This system seamlessly integrates with veterinary clinics, allowing pet owners to purchase prescription medications and pet products conveniently, with updated stocks and availability.

‍

3. Legacy Systems Integration 

If your business relies on legacy systems that cannot be replaced or updated easily, a custom integration can bridge the gap between these older systems and your eCommerce platform. This ensures continuity in operations and allows you to leverage your existing technology investments.

Brand spotlight: Macy's, a well-known department store chain, faced the challenge of integrating their existing legacy systems with modern eCommerce platforms. They adopted a custom POS solution to ensure smooth data flow between their historical systems and their online store that keeps everything unified and operates both ways.

‍

4. Scalability and Future Growth 

As your business expands, you may encounter new challenges that demand a more tailored approach to your POS integration. A custom solution can be designed to accommodate future growth, adapt to changing requirements, and offer flexibility that out-of-the-box solutions may lack.

Brand spotlight: Glossier, a beauty and skincare brand, needed a POS system that could scale with their rapid growth and expanding product lines.

They are also an ideal example of omnichannel POS that updates stock on website, their social media (Instagram store), and in-store.

‍

5. Security and Data Privacy 

For businesses dealing with sensitive customer data, compliance with strict security and privacy regulations is paramount. A custom integration can be specifically built with robust security measures to protect your data and ensure compliance with industry regulations. And you're not sharing data with a third-party subscription source.
