Short answer: a good partner portal shows each partner only their own accounts, deals, and requests; reads that data live from Salesforce; doesn’t charge a license per partner user; carries your brand; and records who did what. Basicloud does this by reading your org live through the API and enforcing row-level rules on every query, with partners signing in to a branded portal instead of your org.
The checklist
1. Can each partner see only their own records?
Partners often share objects — opportunities, cases, orders — but must never see each other’s. Look for access rules that are enforced inside the query, so out-of-scope records are never fetched.
2. Is the data live?
Partner status questions are about now. A portal that syncs a nightly copy answers with yesterday’s data and keeps a second copy of your records to secure.
3. What does each partner user cost?
If every partner contact needs a license, adding a new partner team costs money each time. A portal outside the org avoids per-user Salesforce licenses.
4. Does it look like your company?
Your logo, colors, and domain, a branded sign-in page, and — for international partners — translations.
5. Who can change it?
Partner programs change often. If every new field or rule needs a developer, the portal falls behind. Visual configuration lets an ops lead make the change the same day.
6. Can you see what happened?
Activity logs that show who did what, and when, matter as soon as more than one company works in the same portal.
7. Will it grow beyond Salesforce?
Partner data rarely lives in one system. A portal built to combine live data from several systems — Salesforce today, with NetSuite and HubSpot coming soon in Basicloud — won’t need replacing when it doesn’t.

Where to start
Pick one partner workflow — status of shared deals, open requests, or onboarding tasks — connect Salesforce, scope it to a pilot partner, and expand from there.
