Quartermast is the overnight operator for solo Shopify merchants. It runs the ad-sweep loop — pause losing ad sets, log the rule that fired, write an audit row — only against rules you pre-approve.
The beta focuses on what we can guarantee: rule-driven Meta ad pausing, and a morning digest that links every action back to the rule that fired.
Overnight, Quartermast watches the ad account, the supplier feed, and your margin floor — and writes one digest before the operator wakes up.
Meta + TikTok ad performance and supplier stock feeds, every hour.
Pauses losing ad sets, routes restock to the cheapest qualified vendor, and reprices listings to protect margin.
Emails a concise profit-and-cashflow digest before the operator wakes up.
Every automated action lands in your inbox before you wake up, with the rule that fired and the data behind it. The sample below is the kind of entry any merchant in the beta could see — it explains the mechanism, not a specific customer result.
Rule R-PAC-02 fired: ROAS dropped below your 3-day floor, so the ad set was paused before the next billing window. One click in the audit log resumes it when you’re ready.
