Custom CRM vs Salesforce: Total Cost of Ownership for Mid-Market
TL;DR: A 100-person company's 5-year Salesforce TCO reaches $2M+ when you include licensing, admin staff, customization, and add-ons. A custom CRM costs $910K over the same period — saving $1.1M+ with full code ownership and zero per-seat fees.
The true cost of Salesforce that vendors don't show you
Salesforce's quoted price of $165/user/month is the tip of the iceberg. The true TCO includes implementation ($100K–$300K), a dedicated Salesforce admin ($85K–$110K/year), ongoing customization ($30K+/year), add-ons and integrations ($24K+/year), and 9% annual price increases that compound every year. One company budgeted $5M/year for Salesforce only to discover the true TCO was $9M annually. For mid-market companies, this means $2M–$2.5M over 5 years for software they never own.

Frequently Asked Questions
Is the $2M Salesforce TCO realistic?+
Yes, for a 100-person mid-market company on Enterprise edition. Salesforce's own pricing page shows $165/user/month. Add implementation ($150K), a dedicated admin ($85K/year), customization ($30K/year), add-ons ($24K/year), and 9% annual licensing increases. The math adds up to $2M+ over 5 years.
What are the ongoing costs after the custom CRM is built?+
Hosting on modern platforms like Vercel and Convex costs approximately $5K/year — that's it. You own the code, so there are no licensing fees, no per-seat charges, and no forced upgrades. If you want continued feature development, an optional retainer ($10K–$25K/month) is available. But many clients manage updates themselves or bring in developers only when needed.
What about the risk of building custom?+
The primary risk is choosing the wrong development partner. Mitigate this by requiring: full code ownership transfer, phased delivery (working software in weeks, not months), fixed-price development, and proven case studies with specific metrics. The financial risk of staying on Salesforce (compounding licensing, vendor lock-in) is often greater.
