Identify overlap
Both sides upload their account lists. OnlyCommon reveals only the accounts you share.
OnlyCommon is purpose-built for the two parts of co-selling most tools skip: finding the accounts you share and getting the right sellers talking — without requiring CRM integration.

The co-selling funnel
Both sides upload their account lists. OnlyCommon reveals only the accounts you share.
Pick the top 10–20 shared accounts to work first — active deals, strong relationships, expansion potential.
Team Match introduces the two account owners so they can coordinate quickly.
One-line joint pitch, agreed lead and support roles per account, next meeting on the calendar.
Tag opportunities with partner name and co-sell flag. OnlyCommon keeps the shared-account list — your CRM keeps the deal.
Not the same thing
They're often used interchangeably, but they lead to very different outcomes.
One company hands a lead to the other. Ownership passes over; the sender is out.
Both companies actively work the same account together, from qualification through close.
Team Match
Team Match includes account owners on both sides, so once the overlap is revealed OnlyCommon can trigger intros — sellers can coordinate quickly without unnecessary handoffs.

Practical playbook
A concrete week-one plan you can run with any partner, straight from the shared-account report.
Run one Team Match with your best partner and pull the shared-account report.
Sort the overlap. Pick the top 10 accounts by opportunity strength on either side.
Trigger seller intros — one email per account, both owners in the loop.
Agree per account: who leads, who supports, one-line joint pitch.
Book the first joint conversation with the customer without unnecessary handoffs.
Track outcomes in your CRM with a co-sell tag; review after 30 days and decide what to expand.
Who it helps
Prove partner value with real shared-account numbers and activated sellers instead of logo slides.
Walk into every partner meeting knowing which accounts overlap — and who to loop in on the other side.
Turn partnership activity into measurable shared-account actions and partner-influenced pipeline.
A line is one account row processed by OnlyCommon. If each company uploads about 100 accounts, the total is 200 lines — which fits comfortably in the free plan. That's enough to run a focused test with a partner before you decide to scale up.
Privacy first
OnlyCommon reveals only the accounts that appear on both lists. Everything else stays private to the side that uploaded it.
Non-matching rows are never shown to the other company. Your full list stays yours.
We keep the cleaned match result, not your original spreadsheet.
Your partner can upload and join in one step — no account required to get started.
