name: price-check description: Produces a margin-by-product table and three pricing-scenario data views so the owner can see the full financial picture before making a pricing decision. Accepts optional product name argument. allowed-tools: Read, WebFetch, Bash
Run the pricing analysis. Pull cost and revenue data, build the margin table, and model three pricing scenarios — so the owner can see the numbers clearly before deciding what to charge.
Parse arguments:
PRODUCT_NAME(optional) — specific product or service to analyze; if omitted, analyze all active products
Step 1 — Current margin baseline
Using the margin-analyzer skill workflow:
- Pull QuickBooks revenue by product/service for the last 90 days.
- Pull COGS or direct costs per product from QuickBooks (if categorized).
- Pull PayPal gross sales for the same products to cross-validate.
- Calculate current gross margin per product: (revenue − COGS) ÷ revenue.
Build the margin table:
Product | Revenue | COGS | Gross Margin | Margin %
{product} | ${amt} | ${amt} | ${amt} | {X}%
Flag any product with margin below 20% as a risk.
Step 2 — Three pricing scenarios
For each product (or the specified product), model three scenarios. Do NOT recommend a price — present data only.
Scenario A — Hold current price
- Project revenue at current price × current volume
- Project margin at current COGS
Scenario B — Price increase (+10% to +20%, owner to specify)
- Project revenue assuming 0%, 5%, and 10% volume loss at new price
- Show the break-even volume needed to maintain current profit
Scenario C — Price decrease (−10%, to drive volume)
- Project revenue assuming 10%, 20%, and 30% volume increase
- Show the volume needed to match current profit
Present each scenario as a data table, not a recommendation.
Step 3 — Customer messaging brief
Produce a plain-language brief (for price increase scenarios) the owner can use to communicate a change to customers:
- One paragraph explaining the change
- Three key message options (direct, value-focused, empathetic)
- Suggested timing and channel (email, invoice note, in-person)
Connector failures
If QuickBooks is unreachable, stop — margin analysis requires QB revenue and cost data. If PayPal is missing, run from QB-only and note "PayPal not connected — cross-validation against PayPal sales skipped."
Approval gates
- Never recommend a specific price. Provide data views only — pricing decisions belong to the owner.
- Flag if COGS data is incomplete (many QB setups don't track per-product COGS) and note the gap.
- Never update any prices in QB, PayPal, or any connected system.
Output
Present the margin table, then the three scenario tables side-by-side. If a price increase scenario is being considered, append the customer messaging brief. End with: "Which scenario would you like to explore further?"
