You pay for effort.
Hours billed. Number of resources deployed. A bigger project means a bigger spend, without a shared stake in what it changes.
ImpactIndex™ / Outcome-based billing
When anyone can build software, what matters is building the right thing and building the thing right, ensuring it moves the needle.
01 / The problem
Most businesses pay for hours worked, team size and features delivered, then carry the full risk of turning that work into business results. They still have to justify the spend. What if your technology partner shared responsibility for ensuring ROI?
Hours billed. Number of resources deployed. A bigger project means a bigger spend, without a shared stake in what it changes.
Story points taken up. Features built. A faster launch means a faster invoice. Whether any of it changes your business is still yours to prove.
Adoption. Productivity. Revenue. Agreed business KPIs. Part of our fee is tied to the change you see in your business. You say, “Yes, this was worth it.”
We hold part of our fee until your proof is verified.
AI has changed the economics
AI can accelerate software development and ship in weeks not quarters, and this is table-stakes today. What ImpactIndex™ protects you from is spending for the time that’s ticking, without necessarily proving value or earning a retainer. We empower our customers to pay us by the proportion of change you see in their business.
02 / Three proofs, one commitment
Working software is the first proof. People using it is the next. Business changing visibly is the final proof. Scroll through how each earns its share.
01 / SHIP
The solution is deployed, meets the agreed acceptance criteria and is ready for people to use.
02 / STICK
The solution reaches its target users, who use it and come back to it over and over.
03 / WIN
The KPI improves against its baseline, measured within the time window both teams agreed on.
03 / Shared accountability
During the early discovery phases, both teams define the vision, goals and targets, what to measure and how, before building begins.
Visualize the business change and how the future state would feel like.
Establish the starting point, the as-is state with measured values.
Make dependencies and each team’s contribution explicit.
Track agreed KPIs through transparent dashboards and structured reviews.
Validate the milestone together and release its agreed fee tranche.
04 / See how it works

06 / From the creators
Created by Codewave, drawing on more than a decade of building products with startups, enterprises and public-sector teams.
“If we tie our success to our client’s success, everyone wins.”
“Every dollar a client invests is connected to tangible, measurable change.”
A few useful questions
No. The balance between delivery, adoption and business outcomes depends on your stage, how far the business has been validated and what both teams can reliably measure. We agree on the mix for each engagement. The 30 / 30 / 40 split above is only an example.
During discovery, both teams define the business goal, baseline, target users, data sources and review intervals. A useful KPI can be measured consistently and connected to the change the solution is intended to support.
Make those factors part of the agreement. Dependencies, client responsibilities and the review process need to be explicit so changes can be assessed together. The commercial terms determine how exceptions are handled.
AI can compress execution time, while adoption and business impact still need proof. Choose measures such as workflow adoption, task completion or productivity gains, alongside the quality and acceptance requirements relevant to the use case.
ImpactIndex™ is presented as an open, community-driven framework. Practitioners can contribute KPI templates, measurement methods and lessons from outcome-based engagements. Talk with Codewave about participation and application.
