How to track SaaS price changes across your vendors

SaaS prices change quietly: a plan is renamed, a tier disappears, a per-seat price moves at renewal. A dated price list and a diff are enough to notice in time.

1. Keep one price list

Use a CSV file with one row per plan you pay for, or are considering:

vendor,plan,currency,monthly_price
ExampleCRM,Team,USD,49
ExampleCI,Pro,USD,20

• One currency per row. Do not convert. Compare like with like.
• Monthly price. If a vendor bills only annually, divide by 12 and note it. Keep billing periods consistent between snapshots.
• Same names every time. The vendor and plan names are the key used to match rows between snapshots.

CSV is a plain format (RFC 4180). Quote any field that contains a comma.

2. Snapshot on a schedule

Each quarter, and before every renewal, update the prices from the vendor's pricing page or your latest invoice. Save the file with a date: prices-2026-10.csv.

Write down where each price came from (page or invoice). Public list prices and your contracted prices often differ.

3. Diff the latest two snapshots

Paste the earlier and current lists into the free SaaS price diff. It shows:

• repriced plans, with the old price, the new price and the percentage change;
• new plans;
• missing plans, which were in the earlier list but not the current one.

It compares only what you paste. It does not fetch vendor pages, so the accuracy of the result depends on your snapshot.

4. Act on it

• Bring repriced plans to your renewal talks.
• Check whether a missing plan was renamed or retired, and what it was replaced with.
• Check taxes, billing periods and contract terms before you compare totals.
