The honest readpros and trade-offs, side by side

What works

Deal-specific numbers replace generic industry averages that erode credibility

Three-scenario structure lets economic buyers choose their own conservatism level

Gamma produces a shareable link — economic buyers can share internally without a file attachment

Fireflies extraction from discovery call means reps don't manually fill in a spreadsheet

Salesforce sync ensures business case is visible to management and doesn't live only in email

The trade-offs

ROI model quality depends on how much quantitative information was captured in discovery

Gamma's AI generation occasionally requires manual cleanup for precise number formatting

Conservative scenario assumptions must be reviewed — 50% of stated estimates can still be aggressive

Where people go wrong

The failure modes builders hit most often. Avoiding these is most of the battle.

01Using industry benchmark numbers without stating them as assumptions — economic buyers who know their own data will reject fabricated inputs

02Building business cases for deals below a threshold where the ROI math doesn't convincingly exceed price

03Not addressing the top 3 risks the economic buyer faces — the risk section is often what closes internal approval

04Sending the business case without a context-setting email explaining the assumptions — naked decks get misread

How do I calculate ROI for a B2B software proposal?

Economic buyers require a financial justification before approving a purchase, but sales reps rarely have the time, skills, or data to build a credible business case. Generic ROI templates use industry averages that feel fabricated. The result is a deal stalled waiting for a business case that never gets built well enough to move internal approval.

How do I use discovery call notes to build an ROI model?
