Purchase Justification

Q: How do I know the Purchase Justification output is good?

The skill verifies itself against its own quality checks: The status quo carries a conservative price in the approver's currency; ROI assumptions are labeled and the worst-case line appears; The cheaper alternative was steelmanned, not strawmanned; The ask fits its approval tier honestly (scoped, never split).

Write the purchase request that gets approved — the cost-of-not-buying framing, the ROI math at the approver's altitude, the alternatives-considered section that preempts the obvious pushback, and the right-sized ask for the approval tier. Use when asked justify this tool/hire/equipment purchase, write the budget request, my requests keep getting deferred, or make the business case for this spend. Produces the justification memo: the problem priced, the ROI shown, alternatives dispatched, and the ask sized to its approval path.

“Justify this tool/hire/equipment purchase.”“Write the budget request.”“My requests keep getting deferred.”“Make the business case for this spend.”

What to give it

▸The problem's evidence — the hours lost, the incidents, the workaround's cost ([meeting-cost-meter](../meeting-cost-meter/SKILL.md)-style arithmetic on the status quo); requests without a priced problem are wishes with quotes attached

▸The approver and their currency — who signs at this amount, what they weigh (cost-saving? risk? team velocity?), and what's burned them before ([exec-vs-working-deck](../exec-vs-working-deck/SKILL.md) audience-currency logic)

▸The real numbers — the quote ([vendor-comparison-matrix](../vendor-comparison-matrix/SKILL.md) TCO, not license price), and the honest benefit estimate with its assumptions

▸The approval tiers — where the thresholds sit ($5k? $25k?); the sizing strategy needs the map

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The status quo carries a conservative price in the approver's currency

✓ROI assumptions are labeled and the worst-case line appears

✓The cheaper alternative was steelmanned, not strawmanned

✓The ask fits its approval tier honestly (scoped, never split)

✓Yes is the low-effort path: specific, dated, reversible where true

⚠️ What it refuses to do

Do not request against an unpriced status quo — free inertia beats every paid tool

Do not inflate the ROI — the first checked exaggeration taxes all future requests

Do not leave "use what we have" for the meeting — dispatch it in the memo or lose to it live

Do not split invoices to dodge thresholds — scope real pilots instead

Do not end with "thoughts?" — the ask is specific or the answer is deferral
