A Ternion Vergence productShelfsight Lite. The weekly order question, on one screen.
Shelfsight Lite reads your Vendor Central downloads, works out how Amazon has really been ordering, and shows the purchase orders to expect over the coming weeks, so your team can plan stock and production with confidence.
The problem
Amazon decides how much to buy. You find out when the order arrives.
Built for brands that sell to Amazon as a first-party (1P) vendor through Vendor Central.
Orders swing week to week
Purchase orders jump around even when sales are steady, which makes production and stock hard to plan.
The forecast is a range
Amazon shares its demand forecast as a range of levels (P70, P80, P90) but not the level it actually buys at.
Planning lives in spreadsheets
Weekly downloads are copied into Excel by hand, and the people who need the answer are rarely the ones building it.
How it works
From weekly downloads to next month’s orders.
No integration project. Your team keeps downloading the reports it already uses, and Shelfsight Lite does the rest.
-
Drop in your downloads
Forecast, inventory, sales and purchase-order reports from Vendor Central, in whatever format you saved them. Lite tells you if anything is missing.
-
Learn how Amazon buys
It works out the forecast level Amazon has really been ordering at, averaged over the last 1 to 26 weeks (8 by default).
-
See the orders to expect
Weekly purchase orders at that level and at five points either side, with Amazon’s projected stock week by week.
-
Check it against reality
A pilot log compares predicted orders with the ones Amazon actually sends, so trust is earned week by week.
What’s inside
Everything a planner needs, nothing they don’t.
One screen for the weekly question. No forecasting jargon to learn.
Event alerts
Prime Day, Black Friday and your own promotions are flagged ahead of time, so spikes are planned rather than discovered.
Manual adjustments
Planners can add what they know and the data doesn’t, with every change visible next to the projection.
Sightline assistant
Ask questions in plain English. Answers come only from figures Lite has calculated, and every number is checked against them.
Your timing
Look 1 to 6 weeks ahead from the next order date and lead time, matching how Amazon orders each Monday.
Any file, checked
Files up to 50 MB in any common format. Anything locked, unreadable or unrecognised is turned away with the reason.
Pilot tracking
A running log of predicted against actual orders, the evidence you need before relying on it.
Runs where you work
No IT project required.
Set up for your brand, your products and your calendar of events.
In your browser
A single file that works offline. Your data never leaves your computer.
As a Mac app
Installs like any other app, and keeps your saved data on your own machine.
Hosted for your team
Behind an access code, with nothing stored on the server between visits.
