Your clients have their own ITSM. You don't need to touch it.
Your engineers work in your PSA. Your clients work in their ITSM. Support Fusion keeps both in sync across the company boundary, automatically.
Managed integration for IT service providers. See pricing →
Right now, someone at your company is the integration.
Every new enterprise client means building or explaining a new workaround. That's not a process problem - it's a missing product.
Enterprise clients won't log tickets in your portal
They have their own ITSM and their own workflows. When you ask them to use your portal, they're managing two systems. Most won't do it consistently - and you never know what's in their queue.
Every cross-boundary update is a manual touch
Status changes, work notes, resolution codes, attachments - each one that needs to cross the company line is a manual step. At volume, that's where margin disappears and things fall through.
Your integrations are single-person dependencies
The email rules, scripts, or API connections you've built work until the person who built them leaves, a platform updates, or a new client needs a different setup.
How you connect
Up and running in under a day. No coding, no project, no professional services.
Connect your PSA and invite your client
Register and connect your PSA using API credentials. Invite your client to establish the connection on their side. Each organisation gets its own isolated tenancy - no shared credentials, no cross-account access.
Configure the workflow together
Map how tickets flow between your PSA and their ITSM. Set sync triggers, status translations, closure rules, and which fields are shared. Both teams configure it together. Most setups are done in under an hour.
Work your tickets. They work theirs.
Once live, tickets flow automatically in both directions. Your engineers stay in your PSA. Your clients stay in their ITSM. No portal juggling, no manual updates, no chasing for status.
We'll look after everything and help you along the way.

Before Support Fusion, we had a half-working email integration that nobody fully understood. Now our clients' tickets land in our PSA automatically and we can manage everything from one place.

Built for IT service providers
Six capabilities purpose-built for co-managed IT across company lines.
- Sync
Bi-directional ticket sync
No one has to pull anything. It just syncs.
Every update, comment, and status change flows both ways. Assign a ticket in one platform and it stays bonded across both until it closes.
Watch demo - Sync
Automatic sync
Set it up once. It keeps going.
No manual triggers, no monitoring queues. Once configured, Support Fusion keeps tickets in sync across both platforms until the work is done.

Closure handling
Closure is its own beast. We handle it.
Configure whether the external party can trigger closure in your system, or whether you hold the final close step yourself. Resolution codes, notes, and closure policy all carry through. Some teams automate the full cycle; others prefer to receive a Resolve status and close on their own schedule.

Field mapping
When it's status A on their side, what needs to happen on yours?
You define the business-level rules once. Status, priority, category, board - everything translates automatically. No one has to do that work again.
Watch demo - Configuration
Comment controls
Internal notes stay internal. You control what crosses.
Configure what syncs per ticket type. Keep work notes to your team. Share updates with clients. The rules are yours.

Multi-tenant login
Customer one, customer two, customer three. One account.
One Support Fusion account, multiple tenants. Each organisation's data stays isolated. Built for service providers who manage both sides of a connection.
