How it works
Score fit and headroom
Viability blends how closely the line matches what you do with whether its current spend already covers your price.
Rank the realistic sources
Candidates are ranked so you can lead your pitch with the budget line most likely to fund the purchase without new approval.
Frequently asked questions
Why does the existing budget matter for a new purchase?
Positioning a purchase as a replacement for existing spend is usually far faster to approve than requesting entirely new budget.
What counts as a candidate budget line?
Any existing tool, contract, subscription, or even manual labour cost that your solution could functionally replace or reduce.
What does replacement fit mean?
How closely the existing spend maps to what your solution does — a 5 means it solves nearly the same job, a 1 means the connection is weak.
What if no budget line fully covers my price?
The tool flags that and recommends preparing an ROI case for incremental budget rather than assuming a swap will be approved.
Is this the same as the buyer committee mapper?
No — that tool maps the people in the decision. This tool identifies which existing spend could actually fund the purchase.
