eCommerce POS integration is essential as it connects and creates a communication bridge between your 2 main business channels: your online eCommerce platform and offline POS system. This article will dive into the definition, why, and how to integrate POS with eCommerce, and the top POS systems for eCommerce.

What is an eCommerce POS integration?

An eCommerce POS integration is a digital solution to build a streamlined connection between your eCommerce platform and POS system. In that way, you can pull detailed data in real time directly between 2 systems and process transactions and orders across online and offline channels.

Why do I need an eCommerce POS integration?

According to a study by Harvard Business Review, customers will spend 13% more in physical stores if they’ve conducted prior online research via the brand’s websites. It means that customers who interact via multiple channels tend to spend more in retail stores.

Thus, it’s critical to provide customers with a seamless buying journey from offline to online to meet their growing expectations. Below are some specific benefits.

1. See inventory in real time and avoid overselling

An eCommerce-integrated POS system allows you to view your inventory in real time across online and offline channels. Streamlining your inventory management across channels is vital to any business owner.

  • Track which products may need promotion and which products are hot to order more
  • Restock the right item at the right time and in the right place
  • Transfer stocks between warehouses and locations
  • Avoid out-of-stock and overstock situations to optimize your inventory holding price

You can automate inventory management processes such as:

  • Control inventory levels to ensure timely procurement
  • Set minimum inventory level according to SKU
  • Automated order generation for suppliers with auto-replenishment

2. Eliminate manual data entry

Eliminate manual data entry

Manual data entry, reconciliation, and synchronization are always error-prone and time-consuming. Therefore, another vast added value of integrating an eCommerce website with a POS system is eliminating manual data entry like:

  • Synchronizing order information from in-store and online orders
  • Manage customer, order, and product information in one place
  • No need to update information or reconcile data between channels

This integration reduces your precious time and effort so you can focus on your business.

3. Offer cross-channel promotions and discounts

Manually entering the discount at the POS machine can slow down the customer registration process and increase the risk of fraud. Thus, it’s crucial to have a retail system that seamlessly integrates eCommerce and POS to:

  • Streamline loyalty program
  • Increase customer shopping experience
  • Boost sales and revenue

It provides different strategies to expand your customer base and encourage customers to shop through both channels like:

  • Set up and apply discounts across online and offline channels
  • Suggest promotions and coupons automatically when checkout on POS and websites
  • Accumulate and use loyalty points for online and offline orders
  • Purchase and redeem gift cards at both online and offline stores

4. Leverage better customer data and insight

Integrating POS and eCommerce solutions means that you centralize all your customer data in one place.

  • Display a consolidated view of shopper behavior across both channels
  • Provides more precise insights into your customer preferences and shopping habits

Because customers prefer a consistent experience and interaction across all channels, your retail can improve customer relationships by personalized promotions and offer:

  • Tailored marketing proposals based on purchase history
  • Run multi-channel promotions (discounts, rewards cards, and other loyalty programs)

5. Enable omnichannel order fulfillment

Enable omnichannel order fulfillment

Customers today prefer an easy and fast shopping experience. Most expect delivery within the same day or even hours. Big retailers like Walmart use their retail stores to fulfill online orders:

  • Treat each store as a fulfillment center
  • Added a store locator on the website that shows stock availability in each store
  • Choose stores that are conveniently located on customer routes
  • Forward online orders to fulfillment centers in brick-and-mortar stores automatically
  • Continue the process of online orders at the in-store POS system

If you operate a click-and-collect retail business or online purchase — pick up in-store (BOPIS) model, customers will want to determine which store has the item to place an order and pick it up from there. You can implement this model when integrating your eCommerce with POS systems. This:

  • Allows your customers to purchase products online and receive them in-store or even by the roadside
  • Allows customers to return products purchased online at the store

The customer will have more comfortable delivery options and receive goods faster. Retailers can reduce shipping costs and improve customer satisfaction.

6. Improve customer experience

How does a POS system with eCommerce integration work?

You know the why — now you need the how. Understanding how POS system works with your online store is essential. In general, it’s the automatic execution of retail processes and data sharing between these two channels, including:

How to integrate POS with an eCommerce platform

There are many approaches to integrate your POS system with eCommerce websites. To choose the suitable method, you’ll need to evaluate your current state by asking yourself a simple question: Have you already had an eCommerce website or POS solution in place?

Based on your answer, below are the 3 scenarios and how to integrate your POS and eCommerce website:

1. You’ve already had a POS, but not a website

eCommerce POS situation: You've already had a POS, but not a website

If you have a POS system already, you can integrate it with the most popular eCommerce platforms, which have open API architecture like Magento eCommerce.

  • Ask your POS provider what available options they offer for integration with eCommerce websites. In some cases, you need to enable the built-in eCommerce service of your POS solution.
  • Decide whether to continue with the current provider or switch to another POS system

After that, integrating eCommerce software with POS usually has a clear roadmap from your chosen supplier. First, however, here are the things to keep in mind and the steps to ensure a successful integration:

  • Choose a theme: Some eCommerce platforms allow you to create your theme, while others offer preloaded themes and require customization for changes to match your aesthetic and brand identity.
  • Synchronize your payment gateway: Set up or integrate your POS system’s payment solution providers with your online website. And note that online sales processing fees are often higher than in-store card transactions.
  • Import customer data and inventory: This process can be quick and accurate if you use a data migration service to transfer loyalty points and inventory from the POS system to your online site.
  • Set up shipping: Make sure that your chosen eCommerce platform supports or can integrate with your shipping suppliers and shipping fee.

2. You’ve already had a website but not a POS

eCommerce POS situation: You've already had a website but not a POS

If your business starts with an online website and plans to expand to brick-and-mortar stores, the integration from eCommerce to the in-store POS system is also relatively easy.

  • Determine which eCommerce platform services you want to integrate with your POS system
  • Search for POS software that is compatible with the eCommerce platform you are using. Then, use the above requirements to narrow down the options of POS providers, such as retail POS systems or iPad POS solutions.

The roadmap checklist is similar to scenario 1. However, there are a few other things that you need to evaluate when choosing a POS system.

  • Payment processor integration: Make sure your POS is compatible or can integrate your existing payment providers. Switching to a new processor is always an undesirable decision for many businesses and their customers.
  • Available integration and add-ons: A sound POS system usually has many advanced features like inventory tracking and advanced reporting.
  • Curbside pickup: Customers increasingly love the convenient curbside pickup option, especially during the Covid-19 pandemic for safety and contactless payments. Some POS systems support this option. A plus point to boost your sales.

3. You have neither a POS nor a website

Choose an approach integrate your POS and eCommerce site
