— PL Inventory Forecast & Alerts

Everything you need to reorder on time. Nothing you don't.

PL Inventory Forecast & Alerts is a Shopify inventory forecasting app with low stock alerts built in. It works out how fast each variant sells, tells you the day it runs out, and emails you what to reorder while there is still time to order it.

01 · Forecasting

The date each variant runs out.

Every variant gets a sales velocity measured from your own order history, days of cover at today's rate, and a projected stockout date. Sorted so the closest deadline is first.

Sea Salt Candle · 8ozOut nowOrder now
Ribbed Beanie · Oat3 daysAug 15
Amber Vanilla Candle · 8oz6 daysAug 18
Cedar & Sage Candle · 12oz24 daysSep 5
From your own sales over the last 30 days.
02 · Reorder plan

What to order, and the day to order it.

Set how long a restock takes to arrive, per shop or per variant, and the report works backwards to a reorder-by date and a suggested quantity that covers you past the delivery.

03 · Thresholds & overrides

Alert on days of cover, or on units.

An alert can watch the quantity on hand, or watch how fast it is selling and flag when cover drops below the days you pick. Either way, override it per product or per variant.

04 · Scheduled digests

A reorder email on your schedule.

Send a digest daily or weekly, at a time you choose, in each alert's own timezone. Projected stockouts are called out at the top, with a CSV of every flagged item attached.

Scope an alert by vendor, product type, tag, or location. Availability is tracked per location, so a warehouse can run low while a store still has stock.

06 · Smart re-notification

Flagged once, not every single digest.

An item you have already been told about will not nag you every send. It re-notifies only after it is restocked and dips below threshold again.

— Read-only by design

It reads your store. It never changes it.

PL Inventory Forecast & Alerts installs with four read-only scopes and nothing else. It reads products, inventory, and locations to build your report. To forecast demand it also reads the quantities and dates on your order line items, and nothing else on the order: no customer names, no emails, no addresses, no phone numbers. From those line items it stores one number, the units sold per variant per day, keeps it for 90 days, and never writes anything back to your store.

— How it works

From install to insight in under a minute.

01

Install and set your lead time

Install free from the Shopify App Store, then tell it how long a restock takes to arrive. Override that lead time on any product or variant that has its own supplier.
02

Choose what to watch, and when

Alert on units on hand or on days of cover, scope it by vendor, product type, tag, or location, then pick a daily or weekly digest and the people who should get it.
03

Reorder before the date

The report and the digest lead with whatever runs out first, each row carrying its projected stockout date, a suggested reorder quantity, and a CSV of everything attached.
