The 18-month consulting engagement, billed by the hour with a team of a dozen, is getting harder to sell. Industry commentary points to shorter project cycles, and to a growing interest in outcome-based and even revenue-share pricing. Clients want to know what they’re buying, and they’d like to stop paying for effort that doesn’t move a number they care about. We think that’s a reasonable thing to ask.

Why the old model is under pressure

Long time-and-materials contracts were common during the agile transformation years. They fit a world where the destination was unclear and the journey was the product. But they put all the financial risk on the client. If the work takes longer, the client pays more. The consultant’s incentive, however well meant, is to stay busy.

Outcome-based pricing flips this. The fee depends, wholly or partly, on a result: a defect rate that drops, a process that gets faster, a product that reaches customers by a certain date. Revenue-share goes further, tying the consultant’s reward to the revenue a new product or service earns.

What changes for both sides

Clients have to say what success means in measurable terms, which is harder than it sounds. “Improve onboarding” isn’t an outcome. “Cut the time from signed contract to first delivery from 30 days to 20” is. Consultants have to accept some of the risk, and both sides need to scope in smaller increments, perhaps 8 to 12 weeks at a time, with a clear decision at the end of each one about whether to continue.

Smaller increments also reduce the cost of being wrong. If the first phase shows that the assumption was off, you’ve spent a quarter, not a year.

The pitfalls

Be candid about these. Outcomes often depend on things the consultant doesn’t control: a client’s hiring freeze, a vendor’s delay, a reorganization. A fee tied to an outcome that the consultant can’t influence is a gamble, not a partnership. Metrics can also be gamed. If the fee depends on tickets closed, expect tickets to close, whether or not customers are better off.

Good agreements handle this by naming the dependencies each side owns, choosing measures that are hard to manipulate, and agreeing in advance how to adjust when circumstances change.

At Trayix, we welcome this shift. We’d rather be paid for results than for hours, and we’re willing to share risk where the outcome is something we can influence. We’ll also tell you plainly when it isn’t, and propose a different structure.

If you’re planning your next engagement, try this exercise first: write the outcome in one sentence with a number and a date. If you can’t, you’re not ready to price it yet, and no contract type will fix that.
