How to stop duplicate SaaS spend

Duplicate SaaS is the most invisible form of SaaS waste. Unlike an unused seat (which shows up in the seat report), a duplicate subscription looks fine from every angle. Someone owns it. Somebody uses it. The invoice gets paid on time. The problem is that another subscription in your stack does the same job, or nearly the same job, and together they cost more than one of them would.

This post covers the five patterns we see most often, how to spot them, and how to consolidate without breaking anyone's workflow.

The five duplicate patterns

1. Same tool, different billing emails

The classic. Someone in Engineering signs up for Notion at their personal-but-reimbursed email. Six months later, Ops sets up a separate Notion workspace for the company on a fresh account. Neither person knows about the other. You're paying for two Notion Team plans.

How to spot it: In your subscription ledger, sort by vendor. Two rows with the same vendor name and different billing email addresses. Or two credit-card charges labeled "NOTION" on two different cards.

2. Category overlap — two tools doing the same job

Zoom Business AND Google Meet paid tier. Linear AND Jira. Notion AND Confluence. Grammarly AND ChatGPT Plus for proofreading. Sometimes there's a legitimate reason (security requirements, team preferences, a contract you can't exit yet). Sometimes it's leftover from a migration that never completed.

How to spot it: Add a Category column to your ledger. Sort by category. Two tools in the same category that do the same job is a duplicate candidate.

3. Paid tier of something you have free elsewhere

Paying for Loom Business when you have Vidyard included in your Zendesk plan. Paying for Calendly Pro when your HubSpot already ships scheduling.

How to spot it: For each paid-tier subscription, ask "is this feature already included in something else we pay for?" Look especially at the big platform plans (Google Workspace Enterprise, Microsoft 365 Business Premium, HubSpot, Zendesk). They bundle a lot that you might be buying standalone.

4. Grandfathered plans nobody migrated off

Your ancient Dropbox account from 2018 that's been billing $9/month for five years past when the team actually used it. A GoDaddy hosting plan from when the company had a different product. A Mailchimp account from the first email newsletter that never got transferred to the new marketing system.

How to spot it: Any subscription owned by someone who no longer works at the company. Any tool whose last meaningful use date is over six months ago. Any vendor name you have to ask the team about ("wait, what IS that?").

5. Individual and team accounts for the same thing

Every engineer pays for ChatGPT Plus on a personal card and expenses it, AND the company also has a ChatGPT Team plan. Every designer has their own Figma Professional AND the company has Figma Organization. Pay once for one plan that covers everyone, not twice for overlapping individual and company coverage.

How to spot it: Scan expense reports for recurring monthly software charges. Cross-reference against the company SaaS list. Every match is a candidate.

Detection method

Run this once, then set a quarterly reminder to run it again:

1. Export the subscription ledger. If you don't have one, read the tracking guide first.
2. Add a Category column. Pick 8–10 categories (Engineering, Design, Productivity, Comms, Infrastructure, Finance, Marketing, Ops, AI Tooling) and apply to every row.
3. Sort by category, then by vendor. Visual groupings appear.
4. Flag anything suspicious. Same vendor + same category, or descriptions that mention each other's functions. Write a "?" in a new column.
5. Investigate each flag. Is this actually a duplicate, or do the two tools do different jobs? Ask the owner.
6. Calculate monthly savings. Write the dollar amount next to each confirmed duplicate. This is the budget recovery you're working with.

Most small teams find two to four duplicates on the first pass. Typical recovery: $200–$800 per month, sometimes more.

Consolidation playbook

Finding the duplicate is the easy part. Consolidating without breaking anyone's workflow is the harder part.

For each confirmed duplicate:

1. Pick which tool wins. Usually: the one more people already use, the one with better integrations to the rest of the stack, or the one that's harder to migrate away from.
2. Tell the losing-tool owner. Not through Slack. Not in passing. Schedule a 15-minute chat, explain what's happening and why. Let them push back; sometimes they have context you didn't know about.
3. Migrate data. Every tool has an export. Use it. Don't rely on "the data is still there in the old tool." You'll stop paying, lose access, and then realize you needed something.
4. Set a cancellation date 30 days after migration. If anything's broken, those 30 days surface it. If nothing is, you cancel clean.
5. Cancel through the vendor portal. Not email. Confirm the cancellation email arrives. Forward to finance so AP doesn't get surprised next cycle.
6. Update the ledger. Mark the old row canceled, update the winning tool's usage count.

Prevention

Most duplicates accumulate because buying software is too easy and reviewing it is too rare.

Two rules help:

• Any new SaaS purchase over $50/month requires naming the existing tool it replaces. If nothing exists, document why the category is genuinely new. This forces an explicit decision every time.
• Every quarterly review asks: "Is this in the same category as another tool?" The question is automatic, so it gets asked. The answer is usually no — and the few times it's yes, you've found a duplicate.

Don't try to fix procurement governance through policy alone. Small teams don't have the bandwidth. A 60-minute quarterly review with a duplicate-hunt column catches more than a three-page policy document, and costs nothing beyond the hour.

Closing

Duplicates are the highest-ROI target in a SaaS audit. Unlike downgrading, they don't require anyone to change workflows — you're consolidating on the tool people already use. Unlike canceling, they don't generate friction — the function stays available, just on one account instead of two.

If you only do one thing from this post: sort your subscription list by category, and look for rows that share a category and do similar work. The rest of the playbook is execution. Finding the duplicates is the hour that matters.
