Investment cases that hold up to scrutiny.

Keep your model where it is. prorso holds the case around it: the alternatives, the assumptions, the challenges and the approvals, so the committee sees the reasoning and not only the spreadsheet.

How it fits

Business case

Frame the request, the alternatives, including deferring, and the assumptions behind costs, benefits and timing.

Appraisal

Record NPV, payback, risk, strategic fit and affordability for each alternative, from the model you attach.

Assumption challenge

Ask colleagues and AI to test the optimistic assumptions and flag claims that have no evidence behind them.

Approval within authority

The approvers your delegation of authority requires approve the case, with its conditions on record.

Post-investment review

Compare what happened with the case, the approvals and the assumptions as they stood at approval.

Questions

Does it replace our financial model?

No. Keep the model in your spreadsheet and attach it. prorso holds the case around it: the alternatives, the assumptions and the approvals.

Can we see who approved which version?

Yes. Approvals are recorded on the decision, and every change stays in its history. Lock the case when it goes to committee.

Does it enforce our delegation of authority?

No. You name the approvers each decision needs; prorso does not check spending limits. Your delegation policy decides who should approve.

Who can see a case?

Logs are private to you and the people you invite unless you choose to publish them.
