The short answer: A $20/user/month tool for a 10-person team is $2,400 a year at list price — and $7,000+ over three years once onboarding, unused seats, and renewal uplifts are counted. Half of all SaaS licenses go unused, and the renewal clause matters more than the feature list.
Start with the number — our [SaaS true-cost calculator](/software/saas-true-cost/) stacks monthly fees, seats, renewal uplifts, onboarding, and unused licenses into a three-year total. Free, no signup.
Software is the only business expense that bills you monthly, raises its own price annually, and makes leaving deliberately hard — all in a contract nobody reads. This section covers the contract, the pricing models, the renewal trap, the stack, the exit, and the audit — in plain English, with primary sources.
The contract: what you’re actually agreeing to
- SaaS Contract Red Flags: What You’re Actually Agreeing To — the flagship guide of this section. Auto-renewal windows, uncapped price hikes, termination asymmetry, data-export terms, SLA remedies. Read the MSA, not the pricing page.
The pricing models: per-seat vs. usage, and the math that decides
- Per-Seat vs. Usage-Based Pricing: The Math That Decides — which model fits your team’s shape, the break-even question, and the hybrid traps (platform fees, minimums, overage rates).
The renewal trap: auto-renewal, trials, and price hikes
- Auto-Renewal Traps: The Subscription You Forgot You Had — the trial-to-paid ambush, intro discounts renewing at full list, buried notice windows, and the buyer’s defense checklist. Backed by the FTC’s active ROSCA enforcement.
The stack: accounting, CRM, POS, office suite
- Accounting Software: What It Actually Costs — the QuickBooks tax, per-user caps that force tier jumps, and the honest Xero comparison.
- CRM Cost Escalation: The Free Tool That Bills Like an Enterprise — how a $20/seat starter becomes a $500/month floor plus mandatory onboarding.
- POS Systems: The True Total Cost — software, hardware, and processing, where processing is 80%+ of the three-year bill.
- Microsoft 365 vs. Google Workspace: What 10 People Actually Pay — annual-lock vs. monthly-flex, the 2026 price hikes, and the Copilot confusion.
The exit: lock-in, data export, switching costs
- Vendor Lock-In and Switching Costs: Pricing Your Exit Before You Enter — data gravity is the real lock. Test your exit on day 30, not day 365.
The audit: killing shelfware
- The Shelfware Audit: Finding the Subscriptions You’re Paying For and Not Using — the afternoon audit procedure: statements, owners, login counts, kill list.
The letter: software license audits
- The BSA Letter: What a Software License Audit Notice Means — what the envelope means, the response protocol, and why the second communication goes through a lawyer.
Software is one of five expensive territories we cover: Get Paid, Start, Money, Hire, and Software. One section at a time, done properly.
