Materials & Restock
What actually moved: materials off your completed jobs ranked by usage with part numbers matched from your price book, and - where your techs log site materials - what got used and never billed.
The problem
Every completed job says what went into it, and nobody reads that in bulk. So the supplier order gets built from memory, and the fitting that quietly went on forty jobs last quarter is the one that runs out on a Friday.
The part your techs bill every day is easy to remember. The pattern - what moves, how often, what it costs across a season - is what nobody holds in their head.
What it gives you
- Materials ranked by how often they actually moved, with quantities, job counts, and spend totaled over the lines that carry a recorded cost - that coverage stated, never assumed.
- Part numbers matched from your price book where a clean match exists; a near-miss stays blank rather than guessed.
- Where your techs log site materials: what got used and never billed, ranked by cost, presented as candidates to look at rather than accusations.
- Whether your book uses the on-site materials log at all - stated first, because it decides what the rest can honestly say.
What you need
| Tier | API Key Required |
|---|---|
| Reads | The MCP |
| Needs | The free MCP plus a Housecall Pro MAX-plan API key you generate. A read-only key is enough. |
| Re-run | Monthly for restock, quarterly for the pattern. |
Your first ask
Once it is installed, this is the literal thing you type:
What it cannot do
- It cannot compare billed against used on a book that never logs site materials - most books - and says so in one sentence instead of an empty table.
- Spend totals cover only the lines with a recorded cost; the report names the share.
- Duplicate material names and missing costs get surfaced, not fixed - cleaning the book is the Price Book Auditor's job.
- Requires the MCP (v1.13 or newer) and a MAX-plan API key. A read-only key is enough.
Updates
Every purchase includes all future updates to this skill. Your book decays continuously, so the same job is worth doing again, and each version gets better at it.
The skill checks this site for a newer version when it runs. That request carries the product name and the installed version, and nothing else. There are no account details, no data from your book, no telemetry of any kind. If the check fails for any reason it says nothing and carries on.
Buying it
Sold in the Margin & Materials pack: $49 one time at half price while the shelf is new for all 5 skills in it. The pack is the unit because a home service company that needs this one usually needs the rest of it the same week. What is in the pack. Lifetime is $149 and covers every pack on the shelf plus every skill added to any of them afterwards.
