A ServiceNow manufacturing overage avoidance case study.

How the ServiceNow manufacturing overage avoidance case study unfolded

A global manufacturer reached its first renewal under the 2026 commercial model with Now Assist already running across IT and HR. The account team proposed a large committed assist pool sized to an optimistic adoption forecast, with the overage rate left open and rollover excluded. Each element was framed as future proofing. The manufacturer brought us in on the buyer side to test whether future proofing was the same thing as paying for consumption that might never happen, and to avoid the overage trap before it was signed into the agreement.

The situation

Under the April 2026 model the five legacy tiers were replaced by Foundation, Advanced and Prime, AI was bundled into every tier, and assists became metered, with large agentic actions consuming materially more than simple ones and overage triggering top up charges. The proposal sat on the wrong side of that mechanic in two ways. The committed pool was sized to a headline adoption number rather than to weighted consumption, and the overage rate was left to be set later, which meant any forecasting error would be billed at a rate the buyer had not agreed.

With the renewal date inside three months, the internal default was to accept the assist line as a rounding item next to the user licences. Our first task was to make the assist commitment its own decision, separated from the rest of the bundle, so it could be sized on evidence rather than waved through.

What we found

A four week consumption analysis told a different story than the proposal assumed. The committed pool was roughly a quarter larger than weighted usage justified, because the forecast counted every assist equally while a small number of agentic workflows drew most of the actual consumption. The simple summarisation actions that made up the bulk of the headcount drew very few assists each. Crucially, the open overage rate meant the risk of any shortfall sat entirely with the buyer, and without rollover any unused assists in the oversized pool would simply be lost at period end.

The negotiation

We built the strategy around the assist mechanic rather than around the discount. First, a committed pool sized from a weighted consumption model that counted agentic actions at their true cost, so the manufacturer paid for genuine usage rather than a vendor forecast. Second, the overage rate fixed at signature, so any future growth would be billed at a known number. Third, assist rollover secured so unused consumption carried forward rather than being forfeited. The approach mirrors our broader ServiceNow renewal negotiation advisory.

The manufacturer's team led every conversation. We stayed behind the table, reviewing each revision, drafting counters, and briefing executives before each session.

The outcome

The renewal signed five weeks before deadline. The committed assist pool landed around 22 percent smaller than the proposal, matched to weighted consumption rather than a headline forecast. The overage rate was fixed at signature and assist rollover was secured, which together removed roughly 1.8 million dollars of open overage exposure across the term. The wider estate mapped mostly to Advanced rather than a default Prime migration, holding the baseline the assist line was priced against. The mechanics behind the work are set out in our broader ServiceNow renewal guidance.

Lessons

Three lessons carry beyond this engagement. A committed assist pool sized to a headline adoption number overpays for consumption that weighted usage does not support. An open overage rate transfers the entire forecasting risk to the buyer and should always be fixed before signature. And rollover turns an oversized pool from a sunk cost into carried value, so it belongs in any metered assist commitment.
