How to track supplier price changes

Start before automation
A simple log beats no log when uploads lag real life.
Team-readable
Everyone sees the same history — not notes in three inboxes.
Bridge to CostBeacon
Upload invoices when ready and retire manual rows over time.

Is the template free?

Yes. Download the spreadsheet and use it alongside or before automated tracking in CostBeacon.

What columns should I track?

Vendor, product, unit, old cost, new cost, change percent, invoice date, and notes.

When should I switch to CostBeacon?

When manual updates fall behind — usually after a few weeks of regular invoice volume.
