You only compare what's top of mind
Calls surface this quarter's focus deals; the rest of your shared accounts go unworked.
Partner account mapping · No CRM required
Find shared accounts with any partner — without connecting your CRM.
Each company uploads an Excel or CSV file privately. OnlyCommon cleans and matches the lists, reveals only the accounts you share, and helps connect the right account owners.
- 200 free lines every month
- Your partner doesn't need an account
- Non-matching accounts are never revealed
Most of the accounts you share never get found.
Today, partner account mapping happens on a call — two people with their CRMs open, comparing notes. The catch: you only ever compare the deals that are top of mind, this quarter's focus accounts. The long tail you both share — the accounts neither of you thinks to bring up — stays invisible. And since no one's going to hand their whole customer list to another company, there's no safe way to surface it. For partner managers it's worse: it's not one call but a round of mapping sessions, and then each side still has to go back and rally its own sellers.
No one will share their full list
So there's no safe way to find the overlap you didn't already think to mention.
It's a relay, not a meeting
Map on a call, then each side briefs its own sellers, again and again — and most of the overlap is never discovered.
From two lists to shared accounts — in minutes.
1
Start a match.
Create a Team Match or Direct Match and invite your partner with a secure link. They can join even without an account.
2
Both upload, privately.
Each side uploads their account list. We clean and match it automatically — raw files are deleted after processing, and only matches are ever revealed.
3
Act on the overlap.
Get a clean report of your common accounts, automatic intros between the right sellers, and a shared view to plan bigger deals together.
Everything you need to co-sell with confidence.
Privacy-first by design
Only the accounts you have in common are revealed. Your full list is never shared, non-matching rows are never shown, and raw files are deleted after processing.
The whole overlap, in minutes
See every account you share automatically — not just the handful you'd compare on a call. Map a partner in minutes, instead of across a quarter of meetings.
Smart matching
We normalize messy data and match on domain, company name, DUNS, and VAT — so "Acme GmbH" and "Acme Deutschland" still line up.
Automatic seller intros
Team Match connects the right account owners on each side, so the people who own the relationship actually talk.
Invite any partner by link
Send a secure link; your partner uploads and joins in one step, no account required to get started.
Enterprise-ready trust
Work-email-only access, encryption at rest, audit logs, and configurable data retention.
Why OnlyCommon
Account mapping without the integrations — or the waiting.
Most account-mapping tools make both companies connect their CRMs and join the same network before you can map a single account. OnlyCommon doesn't. Upload a list, invite any partner with a link, and see your overlap in minutes — no integration, no shared platform, no IT ticket.
Map with any partner — even one who's never heard of us. Only you need an account. Your partner just opens a link and uploads once.
