How Plumb sells itself on the App Store
The pitch, integrations and features merchants see before they install: the positioning a competitor is betting on.
“Count a few products a day while you keep trading. Accurate stock without closing to count.”
What it does
Plumb turns the whole-store stocktake into a daily task. It picks what is worth counting — ranked by 90 days of sales, so busy products come round often and the slow tail rarely — and hands staff a short list on POS or in the admin. Counting happens while you… Plumb turns the whole-store stocktake into a daily task. It picks what is worth counting — ranked by 90 days of sales, so busy products come round often and the slow tail rarely — and hands staff a short list on POS or in the admin. Counting happens while you trade: a sale landing mid-count is refused rather than overwritten, and nothing reaches your inventory until you approve it. One click puts it back. Reports show what each variance was worth, and where stock goes missing.

Shopify stores using Plumb
Shoplist is watching Shopify storefronts for the first public install of Plumb.
How Plumb’s install base is moving
Shoplist re-crawls the same storefronts, so every store that adds Plumb, comes back to it or removes it shows up here. The store count also grows when Shoplist finds stores already running it; the breakdown keeps those apart from real installs.

Seen on the storefront, not guessed
If Shoplist shows Plumb on a store, it’s there. Every count on this page traces to code found on a live storefront, re-checked on every crawl.
Code-level
Found in the storefront’s own code
Shoplist matches the scripts, app blocks and pixels Plumb loads on each live storefront. No surveys, no developer-reported numbers, no model guessing installs from review counts.
Re-checked, so the count stays current
Shoplist keeps crawling the same storefronts. A store that uninstalls Plumb leaves the count on the next crawl, so you read today’s install base, not a high-water mark.
Daily
The App Store, read every day
Rank, reviews, pricing and every listing edit are captured daily, so a price change or a ranking slip shows up here the day it ships.
