The top 20 contracts rule

What is the top 20 contracts rule?

The top 20 contracts rule is a portfolio governance method that ranks every SaaS agreement by annual spend and concentrates negotiation effort on the roughly 20 contracts that carry most of the total. The principle behind it is the familiar concentration of spend: a small number of agreements usually account for the majority of what an organisation pays for software, so working that short list returns far more than spreading attention evenly across every renewal. The number 20 is indicative rather than fixed; for some organisations it is 10 and for others it is 30. The discipline is the point, not the exact count.

This rule sits at the centre of portfolio governance because it answers the question every overloaded procurement team faces: where do we spend the hours we have. Trying to renegotiate hundreds of contracts equally guarantees that the largest deals get the same thin attention as the smallest. Ranking by spend and committing real effort to the top of the list is how a lean team produces outsized savings, and it complements the wider sequencing in the SaaS Renewal Playbook.

Why does a small number of contracts carry the spend?

A small number of contracts carries the spend because enterprise SaaS portfolios are dominated by a few platform agreements. The customer relationship platform, the productivity and collaboration suite, the human capital system, the data platform, and the security stack tend to be the largest line items by a wide margin, while the long tail is made up of many small departmental tools. When you sort the register by annual value, the curve is steep at the top and flat for a long way after, which is exactly the shape that rewards a top 20 approach.

That concentration also tracks where the 2026 price pressure lands hardest. The biggest platforms are the ones moving fastest to usage, agent, and outcome meters and pushing AI driven renewal asks that run 20 to 37 percent against a historical 3 to 9 percent annual uplift. Because the largest contracts are both the biggest spend and the steepest increases, the top of the list is where defense matters most. Finding the full set of agreements first often means discovering shadow SaaS spend that never reached the register.

How do you build a top 20 contracts list?

You build the list by pulling every active SaaS contract into one register and ranking it by annual value. For each agreement, capture the annual spend, the renewal date, the notice window, the auto renewal status, the owning team, and the pricing model, because those fields decide both the size of the prize and the timing of the work. Then sort by spend, draw the line at the contracts that together make up the bulk of the total, and flag every renewal that falls inside the next 12 months. The register itself is often the most valuable output, because most organisations have never seen all their SaaS spend in one place.

Once the list exists, assign each top contract a named negotiation lead and a start date set 6 or more months before its renewal. Early starts are what create leverage, because they leave time to gather usage data, benchmark, and run a credible alternative. The same register feeds the broader discipline of governing the SaaS portfolio for savings, where the top 20 is the action layer on top of the inventory.

How do you work the top contracts once you have the list?

You work the top contracts the way you would run any major renewal, but with the calendar driving the sequence. Begin each one 6 or more months before its date, bring usage data on shelfware, tier fit, and adoption, and request legacy pricing explicitly rather than accepting the default uplift. Cap the annual increase at 3 to 5 percent CPI indexed, lock prices at the SKU level, and secure downgrade and seat reduction rights so the next term is protected. For the platforms moving to AI meters, demand ROI evidence before any premium and carve AI features out of automatic billing uplift.

The advantage of the top 20 approach is that it lets you apply this full discipline where it pays. You are not trying to run a rigorous negotiation on a small departmental tool that is not worth the hours. You are putting your best people and your earliest starts against the deals that decide the budget. That focus is also what makes the case for outside help on the largest agreements, since a few contracts justify the effort, which is the logic behind a structured SaaS portfolio review.

Refresh the list every quarter

The list is not a one off. Renewal dates pass, new tools enter the estate, and spend shifts as usage meters grow, so the register needs a quarterly refresh to stay accurate. Each quarter, re rank by current annual value, add any contracts discovered since the last pass, and roll the calendar forward so the next set of renewals is already in view. A register that is reviewed on a fixed cadence becomes an early warning system rather than a snapshot that ages out the moment it is built.

What does the top 20 rule miss, and how do you cover it?

The top 20 rule misses two things if applied carelessly: the fast growing small contract and the strategic risk hidden in a minor tool. A departmental application can be small today and a major line next year once a usage or agent meter scales, so the register has to flag growth rate, not only current spend. And a low cost tool can carry outsized switching cost or sit on critical data, which means its contract terms matter even though its price does not. Cover both by adding a watch list below the top 20 for contracts with high growth or high dependency, and review it alongside the main list.

Used this way, the rule is a focusing device rather than a blunt cut off. The top of the list gets full negotiation effort, the watch list gets monitoring, and the long tail gets light touch governance such as co terming and auto renewal hygiene. That tiered approach keeps the whole portfolio under control while still concentrating the real work where it counts, and it pairs naturally with the discipline of co terming your SaaS portfolio.
