5 min read · Updated 9/1/2026

Run your small business more efficiently with these 20 Chrome extensions for email, invoicing, social media and analytics.

Small business owners wear every hat, and the browser is where most hats get worn. A handful of extensions can replace paid apps and save a surprising amount of time every week. This list covers the essentials in order of impact.

Email and communication

Boomerang lets you schedule emails and reminds you when someone has not replied. HubSpot Sales tracks when your emails get opened. Both work inside Gmail, which keeps everything in one place instead of a separate inbox app.

Buffer's extension queues a post in seconds from any page. Hootsuite's does the same with more scheduling options. For the actual writing, Grammarly catches the typos that slip out when you are replying from your phone.

Analytics and SEO

The Ahrefs SEO toolbar shows you any site's authority and the keywords it ranks for — priceless for checking competitors. Google Analytics's official extension gives you a quick dashboard without opening the full app.

File and document flow

SmallPDF edits PDFs right in the browser, which kills the old download-and-upload dance. Google Docs Offline means the internet dropping does not stop you working.

Frequently asked questions

### How many extensions should a business run?

Keep it under 15. Every extension adds memory usage and every one of them can slow page loads. If you hit 20, look for the ones you installed once and never used again — uninstall those.

### Which extensions are worth paying for?

Boomerang's paid plan pays for itself if you send more than a few scheduled emails a day. HubSpot Sales is worth it once you rely on the open tracking. The rest of the list works fine on free tiers.
