Start with the one people usually mean. Amazon Q Business is the enterprise search and knowledge assistant, and it is one of the few products in this category that publishes real numbers. Lite is $3 per user per month and gives permission-aware answers of roughly a page, single sign-on and file insights. Pro is $20 per user per month and extends answers to roughly seven pages while adding content creation, Q Apps, QuickSight integration, plugins and image processing. That much is straightforward.
The part that catches people is that seats are not the bill. Amazon Q Business also charges for index capacity by the hour, and the meter runs whether or not a single person searches anything. A starter index unit is $0.140 per hour, capped at five units per application, and lives in one Availability Zone for proof-of-concept work. An enterprise index unit is $0.264 per hour and spans three Availability Zones for production. Over an average 730 hour month that is $102.20 and $192.72 respectively, so a production deployment has a floor of roughly $193 a month before anyone logs in. Each unit holds about 20,000 documents or 200 MB of extracted text, whichever comes first, so a 200,000 document corpus needs ten units and the index line alone reaches about $1,927 a month.
Then there is the availability problem, which now outranks the price for anyone shopping. AWS closed Amazon Q Business to new customers on July 31, 2026. Existing customers keep their applications, keep the APIs and keep getting bug fixes and security patches, and AWS has published no shutdown date. What existing customers do not get is new features, because AWS states new feature requests will no longer be considered. If you are not already on it, the price list above is reference material rather than a quote.
New buyers get pointed to Amazon Quick, the successor. Quick publishes four tiers, Free at $0, Plus at $20 per user per month billed annually, Professional at $20 and Enterprise at $40, the latter two requiring an AWS account. Underneath those is the number that changes the math and rarely appears in comparisons: a $250 per account per month infrastructure fee on Professional and Enterprise. It is a fixed cost, so it lands hardest on small teams. Ten people on Professional pay $200 in seats and $250 in infrastructure, which is $450 a month, or an effective $45 per seat against a $20 sticker.
The third product is Amazon Q Developer, and it is worth separating out because a good share of the people searching for Amazon Q pricing are actually looking at it. It is a coding assistant, not enterprise search. Free is $0 with 50 agentic requests a month, and Pro is $19 per user per month with an admin dashboard and IP indemnity. If your evaluation is about finding answers across Slack, SharePoint and Confluence, this is not the product, and comparing its $19 against a search tool's seat price is comparing two unrelated things.
We sell InSearch, so read the comparison with that in mind. Our argument is not that AWS is expensive, because at a hundred seats Q Business was competitive and Quick still is. It is that the sticker price on any of these three is the smallest part of what you will actually pay, and that the product most people are pricing is one they can no longer buy.
The availability change is covered in depth in Amazon Q Business closing to new customers, and the successor comparison in Amazon Q Business vs Amazon Quick Suite. AWS retired more than one first-generation service this summer: see Amazon Kendra maintenance mode, Bedrock Knowledge Bases versus Kendra and Bedrock Agents Classic versus AgentCore. If you are shopping rather than reconciling an invoice, the replacement pages are Amazon Q Business alternatives and Amazon Quick Suite pricing, and permissions during a migration are the subject of Quick Suite document-level permissions.
