Why SaaS Renewals Are a Profitability Problem, Not Just a Retention Problem

Most SaaS companies treat renewals as a box to check. That’s a costly mistake.

Research by Bain & Company — originally published by Frederick Reichheld and W. Earl Sasser Jr. in the Harvard Business Review — found that a 5% increase in customer retention can increase company profits by 25–95%. Yet the renewal moment — the one time per year you can reset terms, pricing, and scope — is routinely left on the table.

While running my last SaaS company, we discovered that several of our best customers were renewing at rates that barely covered our cost to serve them. Support tickets, custom integrations, and third-party data costs were quietly destroying our margins on accounts we thought were healthy.

What Does It Cost to Serve a SaaS Customer?

The true cost goes well beyond infrastructure:

• Support volume: High-touch accounts can cost 3–5x more to service than low-touch ones
• Custom integrations: One-off technical work that rarely gets priced into the contract
• Third-party data or API costs: Often absorbed by the company rather than passed through to the customer
• Account management time: Underpriced in most renewal models

When we started mapping this for every account, we found that roughly 20% of our customers were generating negative gross margin. We were growing revenue and losing money at the same time.

How Should You Calculate Customer Profitability Before a Renewal?

Build a profitability profile for each customer at least 90 days before renewal:

1. Annual contract value (ACV)
2. Direct COGS: Hosting, infrastructure, and data costs attributed to that account
3. Support costs: Tickets x average resolution time x fully-loaded support hourly rate
4. Custom development hours billed internally to that account
5. Account management time: Hours x fully-loaded salary

Subtract items 2–5 from item 1. The result is your true customer margin. According to the 2024 SaaS Benchmarks Report by High Alpha and OpenView, healthy SaaS gross margins sit at 75% or above. Any customer account consistently below 50% warrants a renegotiation conversation at renewal.

What Should You Do When a Customer Is Underutilizing the Product?

Underutilization is one of the leading predictors of churn — and one of the most fixable. In one renewal conversation, a customer on the verge of leaving told us the platform wasn’t delivering ROI. Instead of pitching an upsell, we audited their usage data. They were using less than 40% of the features in their current plan.

We restructured their renewal to include onboarding sessions for unused features and a package aligned to their actual usage. They renewed at a higher tier, their team’s productivity improved, and our cost-to-serve dropped because we weren’t over-supporting a poorly-fitted configuration.

4 Actions to Build a High-Performance SaaS Renewal Process

1. Build profitability profiles for every account. Map revenue against support costs, infrastructure usage, and third-party expenses at least 90 days before the renewal date.
2. Use product usage data to lead the conversation. Before the renewal call, pull utilization metrics and identify underused features. Come prepared with a specific recommendation, not a generic upsell.
3. Train account managers for strategic conversations. The question ‘What are your goals for the next 12 months?’ changes a renewal call more than any pricing tactic.
4. Renegotiate terms on unprofitable accounts. If an account’s true margin is below your threshold, the renewal is the right time to adjust support tier pricing, cap custom requests, or reprice based on actual usage.
   

The Bottom Line on SaaS Renewals

Companies that treat renewals as a strategic moment — not an administrative one — outperform their peers on NRR, gross margin, and long-term customer lifetime value. The renewal isn’t just about getting a signature. It’s the one moment each year where you can simultaneously strengthen the customer relationship and fix the economics of the deal.
