Which Chat App is Best for Your Online Store Team? Slack, Teams, Google Chat Compared

The quick answer for online sellers

For most e-commerce businesses, choosing a chat tool depends on your current software setup. Use Slack if your online store relies on many different apps like Shopify, ShipStation, or a separate inventory system, and you need them all to talk to each other. Pick Microsoft Teams if your back-office work uses Microsoft 365 for things like inventory spreadsheets or accounting. Go with Google Chat if your team lives in Gmail for customer service and Google Sheets for tracking orders, as it’s often included for free with your Google Workspace plan.

Side-by-side breakdown for e-commerce teams

Slack is the top choice for connecting apps. It links to thousands of tools, which is great for e-commerce sellers wanting to pull Shopify order alerts, ShipStation updates, or Gorgias customer service tickets into one place. Its channels keep conversations tidy, like having separate chats for 'new orders', 'supplier questions', or 'marketing ideas'. The free plan only saves messages for 90 days. Paid plans start around $7.25/user/month.

Microsoft Teams comes bundled with Microsoft 365 Business Basic ($6/user/month), which also includes Outlook, Word, Excel, SharePoint, and OneDrive. If you're already paying for Microsoft 365 to manage product catalogs in Excel or supplier contacts in Outlook, Teams costs you nothing extra. While it has fewer direct integrations for e-commerce front-end tools, its video calls are solid for team meetings, and file sharing is secure for sensitive data like sales reports or profit/loss statements.

Google Chat is included with Google Workspace (starting at $6/user/month). If your online store uses Gmail for all customer emails, Google Docs for product descriptions, and Google Sheets for managing inventory levels or tracking PPC ad spend, Chat fits right in. It handles basic team messages and channels well. It might not have as many direct e-commerce app integrations as Slack, but its smooth connection to Google's own tools makes it simple if you're already in that ecosystem for your online business.

When to choose Slack for your online store

Choose Slack when your e-commerce business relies on a mix of specialized tools. This includes apps like Shopify, BigCommerce, WooCommerce, shipping software like ShipStation, customer service platforms like Gorgias or Zendesk, marketing tools like Klaviyo, or inventory systems like TradeGecko. Slack can pull notifications from these apps directly into your chat channels, so your team sees new orders, shipping issues, or urgent customer messages right away. It's also ideal if you work with many freelance product sourcers, ad managers, or virtual assistants from different companies, as Slack makes it easy for them to access specific project channels without mixing up their own company's workspace.

When to choose Microsoft Teams for your e-commerce business

Teams is the smart pick if your online selling operation already uses Microsoft 365. This often happens if you've grown from a physical store or use Microsoft tools for back-office tasks like detailed inventory manifests in Excel, supplier contracts in Word, or company-wide files in SharePoint. You get chat, video calls for supplier meetings, and secure file collaboration all under one Microsoft bill. While not as strong for direct e-commerce platform notifications, it's excellent for managing the internal side of a growing online business, especially if your product data, accounting, or HR processes are already tied into the Microsoft ecosystem.

When to choose Google Chat for your online selling team

If your e-commerce team runs entirely on Google Workspace – using Gmail for all customer service inquiries, Google Docs for writing product descriptions or standard operating procedures (SOPs), and Google Sheets for tracking daily sales, ad spend, or supplier lists – then Google Chat is the easiest option. It's already paid for as part of your Workspace subscription, requires no extra setup, and keeps all your team's communication within the same familiar Google environment. For online businesses with fewer than 10 people, it covers essential chat needs without adding another monthly subscription fee to your growing list of e-commerce tools.

The verdict for e-commerce communication

For an online store team heavily invested in Google Workspace (Gmail for support, Sheets for tracking), use Google Chat. If your e-commerce business relies on Microsoft 365 for back-office operations (Excel for inventory, Word for documents), use Teams. If your online store uses a mix of specialized e-commerce SaaS apps (Shopify, ShipStation, Gorgias) and needs deep integrations to keep your team informed, then Slack is your best bet. Avoid paying extra for Slack if you're already paying for a platform like Google Workspace or Microsoft 365 that includes a chat tool that can meet your basic needs.

How to get started with team chat for your online store

First, check what collaboration tools you already pay for. Are you using Google Workspace for your business email and documents, or Microsoft 365 for spreadsheets and file storage? Use the chat tool that's already included. If you're starting fresh, Google Workspace is a solid foundation, giving you professional email, document editing, and chat for around $6/user/month – a good start for any new online seller. You can always add Slack later if your need for advanced integrations with your Shopify, Etsy, or Amazon Seller Central tools becomes critical for scaling your team and operations.
