Extensiv Order Management - Best Inventory Management
Extensiv Order Management, formerly Skubana, is an order and inventory management system for brands selling across several channels and warehouses. It integrates with leading eCommerce sales channels such as Amazon, eBay, Shopify, and Walmart. It also centralizes orders from each sales channel into a simple dashboard that lets brands pick, pack, and fulfill customers’ orders in one place.
Extensiv’s ability to track inventory in real-time across all warehouses and fulfillment centers is a huge plus for brands with products across multiple locations. You can ensure optimal stock levels by setting custom allocation quantities for every sales channel. Allocations can be set as a percentage of available inventory, which helps protect against stockouts or overselling when the same units are listed on several channels.
Although it has a strong multi-channel inventory solution, some users have found themselves overwhelmed by its many features and require time to learn the system fully. To combat this, Extensiv offers a wide range of resources, including training, guides, and webinars.

Solid Commerce - Best Listing Management
Solid Commerce offers a strong product information management (PIM) module that gives you visibility into every listing. From a single unified dashboard, you can easily maintain product attributes and information like SKUs or ISBNs. Search for individual items from any channel, apply filters, and even organize by fields like manufacturer or storage location. It’s great for quickly finding the exact item you need—no more sifting through spreadsheets or jumping from different eCommerce platforms.
You can also seamlessly update your catalog in bulk or individually. So, whether you’re changing the overall price for a promotion or editing an individual description, Solid Commerce lets you do it efficiently. For more complex products, you can configure kit and bundle relationships. This links the group to the individual SKUs, so when a kit sells, inventory is automatically updated for the individuals, keeping stock accurate.
Solid Commerce is best for mid to large-sized omnichannel merchants and brands looking to consolidate information and integrate processes. The multichannel operations management suite uses consumption-based pricing tied to integration activity, such as inventory syncs and order transmissions with marketplaces, vendors, and shipping platforms, rather than a percentage of sales.
Also, the AI-powered automated messaging “AutoReply” system, now called Takeoff Answers, is sold on its own or included with Commerce Platform plans, which come with 100 replies a month and charge $0.15 per additional reply.
BigCommerce - Best for B2B and Wholesale
BigCommerce is a flexible eCommerce platform offering advanced features for both B2B and B2C eCommerce businesses. Its dedicated B2B edition stood out to us as the top option for wholesalers looking to scale and streamline their customer experience. BigCommerce allows businesses to create different customer accounts and assign specific pricing, promotions, and products for each account. The platform supports volume discounts, which incentivize customers to make larger purchases.
Also, BigCommerce allows sales representatives to create custom quotes for products and orders with negotiable pricing or significant variation based on product details. Sales reps can order on a customer’s behalf and provide personalized pricing tailored to each B2B customer. However, we found the platform’s pricing structure, which ties costs to sales volume, often leads to higher fees as businesses grow quickly.
BigCommerce also allows B2B customers to create custom shopping lists for their organization, simplifying the repurchase process. It offers a portal for customers to view and pay outstanding invoices directly online.
SKU.io - Best for Inventory Costing
SKU.io records every inventory movement as a FIFO cost layer, so each unit carries what you actually paid for it, including landed costs like freight and duty. For brands selling the same SKU on Shopify, Amazon, Walmart, and wholesale, the cost behind each order reflects the batch it shipped from, not a blended average set months ago.
That cost data feeds the profit reporting. SKU.io breaks down margin by order, product, brand, and channel, and you can trace any figure back to the source documents. Amazon sellers get FBA and AWD inbound tracking, settlement reconciliation, and Amazon Ads spend tied to individual SKUs, which makes it easier to see whether a channel still earns money after fees and ad costs. Alerts flag low-margin orders and overdue purchase orders before they turn into month-end surprises.
SKU.io doesn’t replace your books. It posts cost of goods sold (COGS) journals to QuickBooks Online or Xero, so you’ll still need one of them. It also doesn’t print shipping labels, and its warehouse-floor tools are lighter than a dedicated warehouse management system (WMS). Pricing starts at $1,000/month and scales with order volume and SKU count rather than users, with month-to-month contracts. That puts it out of reach for small single-channel stores; SKU.io says it’s built for operations past roughly $1M in revenue.
Shopify - Best for Brick and Mortar Retailers
Shopify’s easy-to-use online store builder integrates with leading sales channels such as Amazon, eBay, Walmart, and Google Shopping, making it a great option for omnichannel sellers. Small to medium brick-and-mortar businesses looking to sell products online can quickly establish an online presence using Shopify. It includes built-in marketing capabilities, including SEO tools and email marketing campaigns.
Additionally, Shopify syncs its online store with several existing POS software, including Square and Lightspeed, allowing businesses to keep their existing software while expanding their customer base to the digital age. For retailers looking to enter multiple online sales channels, Shopify centralizes product information, allowing descriptions, pricing, and availability to update across all sales channels. For new stores, it even has its own POS software to make integration with its eCommerce platform even easier.
Although very large product catalogs with complex variations can make Shopify feel cumbersome or require additional custom development, we found Shopify adept at helping small to medium-sized retailers sell their products outside the traditional four walls.
Linnworks - Best for Amazon, Etsy, eBay
Linnworks is a good platform for businesses selling products on 100+ marketplaces and sales channels, including Amazon, Etsy, and eBay. Businesses can even connect their existing website to Linnworks to manage product listings, inventory, and order fulfillment.
Linnworks provides a central hub for managing bulk product updates, allowing Amazon sellers to update product information, set pricing, and manage product variations without manually changing every listing.
Etsy sellers who create custom or handmade products can avoid overselling them by tracking inventory across every channel, with stock levels syncing every few minutes. eBay sellers can provide their buyers with real-time tracking updates by connecting to more than 70 shipping providers, including FedEx and Amazon Shipping, or 3PLs like ShipBob.
While small businesses can benefit from Linnworks, it is particularly helpful for small and mid-sized sellers that handle a large volume of orders and stock. It best suits eCommerce sellers looking to scale without increasing their administrative workload.
Rithum - Best for Walmart, Target, and Large Retailers
Rithum, formed when ChannelAdvisor and CommerceHub combined, helps eCommerce brands sell on large retail marketplaces such as Walmart, Target, and others. It allows brands and suppliers to manage listings across multiple retailers, track inventory accurately, and fulfill online orders.
Rithum’s dynamic pricing tools enable suppliers to automatically adjust product prices based on market conditions, competition, or pre-defined rules such as the season or time of day. Automated stock management keeps inventory counts accurate across all sales channels. This is key for major retail platforms with a high volume of transactions, helping them avoid stockouts.
Rithum also centralizes orders from every sales channel and applies business rules when stock runs low, such as hiding listings or rerouting orders, so brands don’t sell inventory they can’t ship.
Ecwid by Lightspeed - Best for Social Media eCommerce
Ecwid by Lightspeed made our list because it syncs product catalogs to Facebook, Instagram, and TikTok, and connects to ad and tracking tools on Pinterest and Snapchat. Ecwid helps drive traffic and sales from your existing social media presence through automated ad creation and product tagging to help target and retarget potential customers. It even connects with Google Tag Manager and Meta Pixel to track customer behavior and optimize ad performance.
Ecwid allows influencers and small businesses to monetize their following by selling directly on their social channels. Selling on Facebook and Instagram starts with the Venture plan at $29/month billed annually, and shops on both platforms are only available in some countries.
Finally, Ecwid makes managing orders across multiple social media platforms simple by offering a centralized inventory and order management platform. When a product is sold on one channel, it automatically updates across all channels. It also has a mobile app for adding new products, processing orders, and creating discount codes.
TrueCommerce - Best Integration Options
TrueCommerce features deep integrations with ERPs, warehouse management, and other backend business software. TrueCommerce connects existing ERP systems such as Acumatica, NetSuite, Sage X3, and SAP Cloud ERP with online storefronts and marketplaces.
We found that many eCommerce companies already have inventory management or ERP solutions and may find switching those systems difficult or too costly. Using TrueCommerce, products are centralized across sales channels, and inventory management systems are updated in real time. TrueCommerce helps avoid overselling and stocking out of products that are sold across multiple storefronts.
TrueCommerce also works with leading marketplaces such as Amazon, Walmart, and Wayfair, integrating custom API and EDI connections to ensure every order is received and processed correctly into existing technology.
What is Multichannel eCommerce Software?
Multichannel eCommerce software allows online stores to list, sell, and manage their products across various websites, online marketplaces, and social media outlets. It keeps listings, inventory, and orders in sync between channels like Amazon, Walmart, Shopify, and TikTok Shop. Since Internet retailers depend on digital sales channels for business, multichannel software can help them reach new audiences without adding manual work.
eCommerce stores can sell their goods on a variety of third-party platforms. Digital marketplace websites like Amazon allow users to search for products and buy without ever going directly to the eCommerce website. There are also social media platforms and comparison shopping engines (CSE) that do the same through advertisements. Track these site-specific engagements with multichannel eCommerce software.
Most eCommerce software allows for some multichannel marketing or sales. However, they tend to focus more on managing sales and inventory on a single website rather than on third-party platforms.
Key Features
- Multichannel Advertising: Create a cohesive ad campaign across multiple channels. Post products on digital marketplaces or on social media.
- Marketplace Posting: Sell products through digital marketplaces like Amazon and eBay.
- Product List Management: Control different product listings made on third-party platforms to ensure uniformity. Upload entire product catalogs with accurate product information, pricing, and shipping details.
- Order Processing: Automate order management online. Process sales from third-party platforms, adjust inventory and account for payment and shipping costs to begin order fulfillment.
- Inventory Management: Avoid overselling when advertising product listings on multiple platforms. Sync inventory for real-time updates across all marketplaces.
- Fulfillment Integrations: Route orders to your warehouse, a third-party logistics (3PL) provider, or a fulfillment service like Amazon Multi-Channel Fulfillment, and send tracking back to each sales channel.
- Inventory Costing: Track what each unit actually costs, including freight and duty, to see profit margins by product and sales channel.
- Shopping Cart: Send product data to comparison engines like Google Shopping so buyers can find your products and check out on your store.
Primary Benefits
There are many benefits to promoting products across multiple sales channels:
Streamline Online Advertising
Advertising is essential for an online business. Avoid wasting time repeatedly making the same advertisement for different social media channels. With multichannel eCommerce solutions, a single ad is created, and the software handles the rest. Custom campaigns manage all the image sizing requirements for each channel.
Next, coordinate when the ads go out on each platform. Release them all at once or stagger them based on past audience engagement.
Target Different Demographics by Channel
Every social media platform has a different user base. A user on X will not engage with an ad the same way someone on Facebook will. Use analytics solutions to review target demographics and customize ads for each platform. It may be surprising to learn about an emerging market trend that can be used to advertise products more effectively.
Reach New Audiences through Social Sharing
A successful web store depends on obtaining new customers and retaining repeat sales from existing ones. Unlike brick-and-mortar storefronts, online sellers can’t rely on foot traffic to attract new shoppers. Loyal customers can share the products themselves, making it easy for something to go viral with just a click. Many eCommerce stores, through careful online engagements, have enjoyed increased sales thanks to viral advertising. Social sharing allows satisfied customers to market products for free.
Prevent Overselling
When stock lives in several channel dashboards, a sale on one channel doesn’t update the others until someone changes it by hand. Real-time inventory sync can close that gap and protect your seller ratings, since marketplaces like Amazon and Walmart track order cancellations and can penalize accounts that cancel too often.
Sell Products on Multiple Platforms
Many Internet users prefer to stick to the same social media sites for all their online shopping. By making products available across marketplace platforms, businesses can start selling directly to users even if the customer never visits the business’s online store.
Instead of making the same product post multiple times, multichannel systems provide a single point of entry for all items, which can be turned on or off at any point. This eliminates the need to spend hours creating duplicate product pages for each social media platform. One product listing can be created, and multichannel software ensures it is posted on various marketplaces.
A multichannel listing allows for handling repricing, discounts, and sales specials from a single dashboard. Product information can be updated anytime without worrying about outdated information on the marketplace.
Track Engagement and Reviews on Social Media
Are users talking about your products online? Are they happy with your service? Are they critical? Multichannel software lets you see what users on different platforms are saying about your business.
Social media is a great opportunity to improve customer relations through user reviews. Consumers are now looking at reviews more than ever before committing to an online purchase. A lot of 1-star ratings can hurt your business. If someone has a poor experience ordering your product through another point-of-sale platform, you can make things right through your own media channels. Respond to reviews on other websites to show your commitment to above-and-beyond customer service.
Popular eCommerce Sales Channels
Multichannel software is designed to be compatible with various online marketplaces, social media platforms, and Comparison Shopping Engines. The ones you need depend on what sort of audience you want to reach:
| Marketplaces | Social Media Platforms | Comparison Shopping Engines (CSE) |
|---|---|---|
| Amazon | X | Google Shopping |
| eBay | Amazon Sponsored Products | |
| Walmart | Microsoft Shopping | |
| Etsy | ||
| TikTok Shop | YouTube | |
| TikTok |
Pricing Guide
Multichannel eCommerce software pricing usually scales with order volume, sales, or number of channels rather than users. Many back-office tools, including Linnworks and Extensiv, don’t publish prices and quote based on order volume, so expect a sales call above the low-cost tier. Budget separately for marketplace fees, payment processing, and implementation or training.
- Low-Cost ($5–$39/month): Fits small sellers running one storefront plus a social shop or a single marketplace. Examples include Ecwid by Lightspeed and the entry plans from Shopify and BigCommerce.
- Mid-Range ($40–$399/month): Fits growing stores selling across several marketplaces with a small operations team. Examples include Shopify’s Grow and Advanced plans, BigCommerce’s Growth and Scale plans, and Ecwid’s Business and Unlimited plans.
- High-End ($400–$1,499/month): Fits brands with multiple warehouses, 3PLs, or wholesale accounts that need dedicated inventory and order management. SKU.io falls in this range.
- Enterprise ($1,500+/month or custom): Fits large retailers and brands selling across many marketplaces or into big-box retail. Examples include Shopify Plus, BigCommerce’s Performance plan, Rithum, and TrueCommerce.
