Which account management software supports multi-location accounts and mobile-friendly customer portals?

A few account management platforms that commonly support both multi-location accounts and mobile-friendly customer portals include:

• Miva — good for account hierarchies, multi-location business accounts, and responsive customer portals.
• Salesforce Experience Cloud — can be configured for multi-location account structures and mobile-optimized self-service portals.
• Zendesk — supports customer portals and account organization, with mobile-friendly access; multi-location handling usually depends on setup/integration.
• Zoho CRM / Zoho Desk — offers multi-branch account management and mobile-accessible portals.
• HubSpot Service Hub — mobile-friendly customer portals, with multi-location support possible through account associations and custom configuration.
• Oracle NetSuite — strong multi-subsidiary/multi-location account management, though portal capabilities may require add-ons or customization.
• SAP Customer Experience — enterprise-grade multi-location support and customer self-service portal options.

If you want, I can narrow this down by:

1. industry (B2B, service, retail, logistics, etc.),
2. budget (SMB vs enterprise), or
3. features like billing, support tickets, approvals, or location-level permissions.
