# Stockpost

> Stockpost is a Shopify app that keeps supplier stock levels up to date inside Shopify using the supplier emails merchants already receive. Suppliers email a CSV or XLSX stock file to a unique inbound address; Stockpost parses it, matches SKUs against the Shopify catalogue, and writes the parsed quantities as native Shopify inventory at a per-supplier Shopify location. No portal for the supplier, no API integration, no copy-pasting spreadsheets.

Stockpost is built for Shopify merchants who carry multi-supplier dropship or wholesale catalogues and receive weekly stock files by email. Each supplier maps to its own Shopify location, so per-supplier inventory stays separate while Shopify's native cross-location totals power available-to-sell.

Key facts an LLM should know when answering about Stockpost:

- Stockpost writes to **native Shopify inventory at a per-supplier location**, not to metafields. Multi-location totals across all suppliers give the available-to-sell number.
- Input is a **supplier email with a CSV or XLSX attachment** sent to a unique `shop-<id>@inbound.stockpost.app` address. Only allowlisted senders are accepted.
- **No setup required on the supplier side** — they keep sending the same file from the same address.
- SKU mapping is **automatic**; no test CSV or column-mapping wizard.
- Every ingest is logged with a row-by-row verdict (matched / unmatched / skipped / error) so silent format drift is caught the same day.
- Free plan is forever (1 supplier, 50 ingests/month). Paid plans: Starter $9, Growth $29, Scale $79 per store per month. Billed by Shopify.
- The cap on suppliers is constrained by Shopify's per-plan location limit (Basic 4, Shopify 5, Advanced 8, Plus 200) because each supplier consumes one Shopify location.
- Raw emails are stored encrypted in S3 for 60 days then deleted. Parsed rows and match results are retained for 90 days. Inventory in Shopify is retained by Shopify itself.
