# More sources

More signal behind the brief. The brief itself is unchanged in shape.

## Shopify — product-level detail

The best source for anything the brief says about specific products.

| Pull | Use |
|---|---|
| Per-SKU revenue and units | Top performers and slow movers, which is the spine of the brief |
| Variant performance | Which size, colour, or option is actually moving |
| Inventory on hand | Never push a product that's about to stock out |
| Product images and descriptions | Flow straight into asset generation downstream |

**The inventory check matters more than it looks.** A brief that recommends pushing a product with eleven units left creates a campaign that sells out in two days and disappoints everyone it reached. Cross-check stock before anything goes on the push list.

## Stripe

Subscription and recurring revenue, where the business has any. Useful for spotting a product whose one-time sales are flat but whose recurring base is growing, which changes what to promote and how.

## What doesn't change

- The brief is still strategic output only — what to push, what to offer, what to hold. No calendars, no assets. Those live in `social-content-engine`
- Still built from actual sales data, never from category assumptions
- Still names specific products with specific numbers
- The sales-CSV path still produces the same brief

## Direct invocation

If the owner asks for a sales brief, run this and return the brief. Don't route them anywhere else.
