Ecommerce software guide: categories, features, and how to choose
Choosing ecommerce software is hard because there isn’t one product that does everything. A typical online business uses a store platform, a way to manage inventory and orders, payments, shipping, accounting, and marketing tools, and the real question is how well they work together.
This guide explains the main categories of ecommerce software, gives well-known examples in each, and shows how to choose. Examples aren’t rankings or endorsements. Plans, features, and prices change often, so check each vendor’s current information before you decide.

Features to look for in ecommerce software
Every business is different, so the right features depend on how you sell. These are the things to check first:
- Integrations. Software that connects natively to the rest of your stack saves time and avoids workarounds. Check the vendor’s integration directory, not just its marketing page.
- Inventory accuracy. Stock levels need to update across every channel. In the State of Commerce Ops 2026 report, only about a third of retailers (33.2% in the UK and 37.2% in the US) reported excellent inventory visibility across channels and warehouses.
- Multichannel support. If you sell on marketplaces as well as your own site, check how the software handles listings, orders, and stock across them.
- Shipping and fulfillment. Look for rate comparison, label printing, tracking, and the carriers you use.
- Payments and checkout. Check supported payment methods, fraud tools, and fees.
- Automation. Rules for routing orders, updating stock, and sending notifications cut manual work and errors.
- Security and compliance. For anything that touches payments or customer data, look for PCI DSS compliance, two-factor authentication, and data encryption.
- Ease of use. Software your team dislikes won’t get used, so try it before you commit.
- Room to grow. Check whether the plan and the product still work when your order volume, channels, or warehouses increase.
Ecommerce software examples by category
Store platforms
A store platform hosts your site, product pages, and checkout. Shopify is a hosted all-in-one platform with themes, checkout, and an app store, which suits sellers who want to get online quickly. BigCommerce is another hosted platform with a wide range of built-in features and integrations. WooCommerce is an open-source plugin for WordPress, a good fit if you want control over design and content. It’s free to download, but you still pay for hosting, a domain, and many extensions, and it takes more technical work than a hosted platform. Linnworks integrates with all three, so orders and stock stay in sync with your inventory system. See our guides to the cost of a Shopify store, open-source ecommerce platforms, and the best ecommerce platforms.
Inventory, order, warehouse, and multichannel management
Your store platform isn’t built to manage stock across several channels and warehouses. Linnworks centralizes inventory, orders, listings, shipping, and warehouse management, with 100+ native channel integrations and stock sync across channels in under 10 minutes. Its shipping management connects to 70+ carriers. See inventory management, order management, warehouse management, and multichannel selling. Rithum (formerly CommerceHub and ChannelAdvisor) is another option focused on marketplaces, drop shipping, and listing management. For comparisons, see our guides to multichannel ecommerce software and multichannel inventory management.
Payments and point of sale
Stripe is an online payment processor with an API that lets businesses build payments into a website or app. Square combines payments and point-of-sale hardware and software for in-person and online selling, and its online store builder is Square Online (Square acquired Weebly in 2018, and Square Online is now its main offering for new sites). Linnworks integrates with Square. Compare transaction fees, payout timing, supported methods, and fraud tools for your markets.
Accounting
QuickBooks Online is widely used accounting software for small businesses. Connecting your order and inventory data to your accounting software cuts manual entry and gives you profit by channel. Linnworks has a QuickBooks Online integration, and SyncTools syncs sales, purchases, refunds, and taxes from Linnworks to QuickBooks Online and Xero.
Shipping
ShipStation is shipping software for printing labels, comparing carrier rates, and tracking orders from stores and marketplaces. It has a Linnworks integration. Check which carriers and services you need, and how the software handles surcharges. See our guide to getting better shipping rates.
Email marketing
Mailchimp, Constant Contact, and Klaviyo are widely used for email campaigns, automation, and segmentation. They differ in features, pricing models, and store integrations, so test deliverability and reporting with your own list instead of relying on a comparison table. Whatever you choose, make sure it connects to your store so you can segment on purchase history and send abandoned-cart reminders.
Analytics and customer service
Google Analytics is a free tool for tracking traffic and conversion, and business intelligence tools such as Tableau can go further across data sources. For service, Zendesk, Salesforce Service Cloud, and Freshdesk track inquiries, assign tickets, and build knowledge bases. Pick tools that connect to your store and order data so agents can see order history.
Amazon product research
If you sell on Amazon, research tools such as Jungle Scout and Helium 10 help you find product opportunities, keywords, and competitors. They’re worth considering if Amazon is a significant channel, but weigh their cost against how many products you’re researching. For wider channel planning, see our guide to selling on your own website vs. marketplaces.
How to choose ecommerce software
- Map your workflows. List what you do from listing a product to delivering it, and where it’s manual or error-prone.
- Prioritize integrations. Decide which systems must connect, and check native integrations before anything else.
- Shortlist two or three options per category, and compare them on your priorities, not on feature counts.
- Test with real data. Use a trial or demo with your own products, orders, and channels.
- Check the full cost. Look at transaction fees, app and extension costs, usage tiers, onboarding, and support, and confirm current pricing with the vendor.
- Check the exit. Ask how you can export your data if you switch.
Avoid buying tools with overlapping features, and avoid a stack where every tool is a separate login that doesn’t share data. The more your tools exchange data automatically, the less your team re-enters.
FAQs about ecommerce software
Check the vendor’s security documentation and compliance. For anything that handles payments, look for PCI DSS compliance, and look for two-factor authentication and data encryption. Read independent reviews and ask the vendor how it handles data breaches.
It depends on the product. Native integrations are the easiest. Many tools also have an API, and you can connect others with an automation tool such as Zapier, but that takes more setup, testing, and maintenance.
Some platforms are free to download, such as WooCommerce and Magento Open Source, but you still pay for hosting, extensions, development, and support. Treat free software as a different cost structure, not no cost.
Most store platforms include discount codes and abandoned-cart tools, and dedicated email tools such as Mailchimp, Constant Contact, and Klaviyo add segmentation and automation.
Zendesk, Salesforce Service Cloud, and Freshdesk are widely used. Choose one that connects to your store so agents can see order history.
Inventory and order management software keeps stock and orders in sync across channels. Linnworks connects to 100+ native channel integrations and syncs stock in under 10 minutes. See our guide to inventory management systems.
