Shopify’s 7 Best Omnichannel Inventory Management Software (Reviewed)

Jane finds a pair of sneakers she loves on your Shopify store. Later, she spots them on your TikTok Shop and finally decides to buy, only to be hit with an “out of stock” message.

She checks your website again and it still shows as available. Confused and frustrated, she abandons the purchase altogether.

Today’s shoppers don’t just buy from websites. They browse on Instagram, shop on TikTok, check reviews on Amazon, and pick up in-store. 

This is exactly why you need omnichannel inventory management. It means going beyond just selling in more places and making sure your inventory is synced, orders run smoothly, and customers get the same seamless experience on every sales channel.

We dive deeper into omnichannel inventory management and review top Shopify apps that can help you with this.

Importance of Omnichannel Inventory Management for Shopify Stores

80% of consumers use multiple channels to complete a purchase, so selling on multiple channels sounds like a no-brainer. More reach, more sales. 

But without omnichannel inventory management, those extra sales won’t translate into real ROI. 

Here’s why it’s essential and the benefits it brings.

1. Brings all channels together

The most obvious benefit of omnichannel inventory management is getting access to real-time inventory data across all sales channels, whether it’s Shopify, Instagram, eBay, or brick-and-mortar stores. 

Every sale, return, or transfer updates instantly across every platform, so your stock numbers are always accurate, no matter how many channels you’re juggling.

2. Optimized stock allocation 

When you’re selling across multiple platforms, you’re just playing catch-up with spreadsheets that are accurate one minute and outdated the next. 

With real-time data on what's selling on which platform, you can distribute stock more efficiently across locations, be it warehouses, offline stores, or Amazon marketplace so that products are available where they’re needed most. This helps avoid stockouts and overstocks across channels.

3. Faster and smarter reordering

Omnichannel inventory management makes reordering easy and fast for Shopify stores by linking all sales channels into one dashboard. You can quickly see what’s selling where, use past trends to order the right amount, and place well-planned POs. 

Cross-referencing spreadsheets or using channel-specific reports is slow and error-prone. You’re often placing smaller, separate orders for different channels and missing out on the opportunity to negotiate better bulk pricing or lead times with suppliers.

4. Higher NPS 

Happy customers are returning customers. But, nothing frustrates them more than delayed shipments or unavailable products. 

When you know what’s where, you can commit to and deliver on promises, ensuring customers get their orders faster and more reliably. 

When they trust you to deliver, they’re more likely to recommend your store to others.

5. Consistent brand experience

Your brand isn’t just your logo or your products. It’s the experience you provide. 

Omnichannel inventory management allows you to create an experience that stays consistent, whether someone buys on your Shopify store, your Facebook Shop, or in person. Customers see the same availability and get the same fast service.

This builds trust and recognition, turning casual buyers into repeat ones.

What Makes an Omnichannel Inventory Management System "Best" for Shopify? 

The “best” omnichannel inventory management app for Shopify is one that keeps your inventory tight, your customers satisfied, and your business ready to grow across every channel.

To do just this, it should have the following features.

1. Real-time inventory sync across all sales channels

The primary purpose of any omnichannel inventory management app is to sync inventory in real-time across every platform you sell on. 

Whether it’s Amazon, Faire, Shopify POS, TikTok, YouTube, Facebook, Target, eBay, Etsy, or Walmart, the app should instantly update stock levels whenever a sale, return, purchase, or transfer happens. 

This saves you the headache of manually reconciling numbers and gives you a single source of truth, no matter where inventory moves.

2. Demand forecasting capabilities 

A great app doesn’t just track what’s happening now, it also tells you what’s coming across the channels. You get actionable insights to plan ahead, reduce waste, and keep cash flow steady.

Demand forecasting uses historical sales data, seasonal trends, and channel-specific patterns to predict how much stock you’ll need and when. 

This means you’re not caught short during a TikTok viral spike or overstocked after a slow month on Etsy. 

3. Automation for reordering, purchase orders, and stock alerts

Time is money, and the best apps save you both by automating repetitive tasks. 

They can set up low-stock alerts to ping you (or your team) when inventory dips, trigger purchase orders based on preset rules, and even send those orders to suppliers all from one platform. 

This kind of automation cuts down on manual mistakes, speeds up restocking, and keeps your sales running smoothly on all channels.

4. Reporting and analytics

You can’t improve what you can’t measure. An ideal omnichannel inventory management software offers you automated reporting to course-correct and double down on effective approaches. 

They break down sales by channel, highlight top performers, track inventory turnover, and COGS, and even flag slow movers. 

Whether it’s a quick snapshot of inventory health or a detailed report with customizable filters, you can easily spot trends, tweak strategies, and make educated decisions for higher profitability.

‍5. Integrations with WMS & 3PLs

As your Shopify store grows, you might lean on warehouse management systems (WMS) or third-party logistics (3PL) providers. 

The best apps play nice with these tools, syncing inventory and orders seamlessly between your Shopify setup, warehouses, and fulfillment partners. 

This ecosystem ensures stock levels stay accurate, orders route to the right location, and your 3PL can pick, pack, and ship without missing any detail, keeping your operation scalable and stress-free.

Tips for Improving Omnichannel Inventory Management on Shopify

Here are some practical tips to make omnichannel inventory management work even better for your store.

1. Automate where possible

Make automation your best friend when managing inventory across multiple channels. 

Set up low-stock alerts to notify you when inventory drops below a set threshold, so you can reorder in time and avoid costly stockouts. 

Automate purchase order (PO) creation to keep stock flowing smoothly without you having to babysit every channel.

Beyond that, use automation to forecast future demand and generate channel-specific reports to make educated decisions.

Prediko handles all this and more, so you can focus on growing your business, not micromanaging inventory.

2. Maintain consistent pricing across channels

Nothing confuses or frustrates customers more than seeing different prices for the same product on your Shopify store vs Instagram. 

It is important to make sure that the price listed is uniform across all platforms. This not only builds trust but also simplifies your backend, fewer pricing discrepancies and less time fixing mistakes. 

In case you're running channel-specific promotions, make it clear that the markdown of the price is exclusive to that platform.

3. Analyze trends & seasons across channels for better forecasting

Not every channel performs the same throughout the year. Your Shopify may spike during holidays, while your physical store peaks on weekends.

Regularly review your channel-specific sales reports to spot trends, adjust stock levels, and avoid over- or under-ordering inventory. 

Apps like Prediko automatically analyze your past seasonality, growth trends, and historical sales across channels to predict future inventory needs. It also gives access to sales and inventory reports for accurate decisions.

4. Strategically bundle products & SKUs for different channels 

Some products sell better in bundles on certain platforms.

For example, offering a skincare set on Amazon might perform better than selling individual items, while Instagram shoppers may prefer single products. Bundle slow-moving products on a channel with bestsellers to clear out inventory and increase sales.

Prediko allows you to forecast inventory demand at both the bundle and individual SKU levels so you can plan and stock up accordingly. 

Choosing the Right Omnichannel Inventory Management Software for Your Shopify Store 

Not every tool is built the same and when you're juggling sales across Shopify, marketplaces, and social platforms, your inventory management app needs to be more than just “good enough.”

Here’s a quick framework to evaluate the right fit for your store

• No. of sales channels: See if it can accommodate all your existing sales channels. Can it grow with you as you add more SKUs, sales channels, or warehouses?
• Automation: How much manual work can it eliminate? Look for PO automation, restock alerts, and channel-specific demand forecasting.
• Compatibility: Check integrations with existing tools (e.g., QuickBooks, Shopify POS). 
• Budget: Focus on ROI, not just cost. The right app would pay for itself in accuracy and saved hours, mistakes, and sales. 

Prediko checks off all the boxes. Built specifically for Shopify brands, it combines AI forecasting, PO automation, low stock alerts, raw materials management, and seamless multichannel sync, all wrapped in an intuitive interface your team will actually enjoy using.

If you’re ready to move past spreadsheets and clunky apps, Prediko might just be the right omnichannel inventory management software for you. Use it free for 14 days.
