I Checked 20 SaaS Pricing Pages to Find the Real Cost of B2B Integrations — Here's What Vendors Hide

说明与用途

用户无法通过隐藏费用（如API访问、层级要求和中间件成本）确定B2B集成的真实成本。该项目创建了一个包含55个集成对的开放索引，提供交互式计算器，揭示隐藏费用和所需最低计划层级。

问题

Users cannot determine the true monthly cost of B2B integrations because vendors hide additional fees such as API access, tier‑gate requirements, and middleware costs.

结果

The project revealed three key hidden cost traps: Salesforce’s $25/user/month API fee, HubSpot’s tier jump for Slack integration features, and the cost advantage of middleware like Make.com at larger team sizes. The open index now allows teams to calculate true integration costs and avoid surprise expenses.

工作流

• 1. Scrape live vendor pricing pages and developer API docs for 20 SaaS products.
• 2. Verify each price against the vendor’s official documentation and timestamp the source URLs.
• 3. Identify hidden costs such as API access fees, tier‑gate requirements, and middleware subscriptions.
• 4. Build an interactive calculator for each integration pair with team‑size slider, tier toggle, and incremental mode.
• 5. Publish the data in a free, open index and host the source code on GitHub.
• 6. Monitor vendor changes and flag mismatches for review.

证据

Salesforce charges $25/user/month EXTRA for API access on Professional ($100/user). A 40-person team pays $12,000/year just for the right to connect their tools.

HubSpot's Starter plan is $20/seat — but Breeze AI in Slack, advanced workflow notifications, and record-creation shortcuts all require Professional or above.

The native-vs-middleware math flips at team size. A $30/month Make.com subscription often beats a $20→$100/seat tier jump.
