A gain-share baseline records where a process stands before the provider starts, using data pulled from the client's own systems, normalized for volume and agreed in writing. Choose measures the provider can influence, decide in advance what would change the baseline, and cap the share. Then run a calibration period before any gain-share is paid.
Gain-share is attractive and still rare. HFS Research found only 19% of service contracts materially use gain-share or risk-reward pricing, while about 80% of leaders expect outcome pricing to grow. HFS describes gain-share as the bridge to outcome pricing, because outcomes rarely depend on one party alone. A solid baseline is what makes that bridge hold.
Step 1: Choose measures the provider can influence
Pick measures the service actually changes: turnaround time, hours spent, error rates, days past due. Avoid measures driven mostly by things outside the provider's control, such as total revenue or market prices. If you cannot explain how the provider moves the number, do not share on it.
Step 2: Pull the baseline from source systems
Pull the data straight from the ERP, ticketing or agency management system for an agreed period, not from estimates or interviews. Record the queries or reports used, so the same numbers can be pulled again later the same way.
Step 3: Normalize for volume and seasonality
If volume doubles, total hours will rise even if the work gets faster. Express baselines per unit: hours per invoice, days per renewal, errors per thousand transactions. Where the business is seasonal, compare like months or use a full year.
Step 4: Agree what changes the baseline
Write down the events that trigger a baseline review: an acquisition, a new ERP, a change in payment terms, a major new customer. Without this, the first big change turns into an argument.
Step 5: Set the share, the cap and the floor
Agree the percentage of verified gain paid to the provider, an annual cap on total fees, and a fixed floor fee that covers the provider's cost to run the service. The cap protects the client from runaway fees. The floor stops the provider cutting corners when a month is slow.
Step 6: Run a calibration period before gain-share starts
Run the service for 30 to 90 days on the floor fee alone. Use the period to confirm the measures behave as expected and the data pulls are reliable. Gain-share starts only after both sides sign off the calibration.
At Agentic MSP, the baseline is pulled during the fixed-price Business Process Workshop, and gain-share is billed quarterly after verification. See outcome pricing for how the floor, share and cap fit together.
