Inventory & made-to-order

One number, correct everywhere: that's the inventory promise. A sale at the booth, on your website, or through Square all draw down the same count. Handmade inventory has more moods than "in stock / out of stock," so products support a few availability styles — pick per product.

The four availability styles

1. Untracked — leave stock blank. For things you can always make more of and never count. The website sells freely; no low-stock noise.
2. Tracked — set a stock number. Sales decrement it, event allocations reserve against it, and low-stock alerts fire before a show would clean you out. At zero, the website shows sold-out and starts collecting notify-me emails (see below).
3. Made to order — tracked, but hitting zero doesn't stop sales. The website keeps selling as a backorder, stock goes negative, and you get an email telling you exactly how many to make. For the "I can print another one this week" catalog.
4. Custom order — no instant purchase; customers describe what they want through the quote form (with photo/file attachments) and you price it personally.

There's also a paused switch — the product stays visible with a label you choose ("Back after the holidays"), can't be bought, and collects notify-me emails until you flip it back.

Notify-me lists

Sold-out and paused products never dead-end. Customers leave an email; you'll find the list on the product's edit page (Restock waitlist) — warm leads for exactly the products people wanted and couldn't buy. Email them when you restock; that's the whole feature, no spam machinery attached.

The movements ledger

Every stock change is recorded with a reason — sale, restock, event allocation returned, manual correction — so "why is this at 3?" always has an answer.

Costs (optional, worth it)

Set a per-product cost to make and every report upgrades from revenue to profit. A simple unit cost is all it takes — MakerEventsOS deliberately doesn't do raw-materials recipe math (if you love that, Craftybase does it well and the two coexist happily; import your unit costs by CSV).
