Integrate your tools without the spaghetti (vs Zapier & point-to-point)
What an integration hub is, how it differs from Zapier and point-to-point scripts, and why one event should ripple through every system that needs it, with its trail attached.
An integration hub sits between every tool your business runs and forwards each event to every other system that should hear about it, a booking becomes a CRM contact, an invoice, a held calendar slot and a marketing target within seconds. Unlike point-to-point scripts or brittle Zaps, new connections are point-and-click and every event carries its trail.
You bought eight tools and they pretend not to know each other. The booking platform talks to nobody. Accounting hears about new revenue when the bookkeeper opens the invoices folder. The CRM has yesterday's contacts. You stopped trusting any single dashboard because you know what didn't get copied across, the business runs as eight islands with a person paddling between them.
What is an integration hub (and how is it different from Zapier)?
An integration hub is a central layer that sits between all your systems, listens for events, and forwards each one, transformed as needed, to every other system that should react. Zapier and similar tools wire one trigger to one action, which is fine until you have dozens of them. The sprawl is real: Okta's analysis found large organisations run an average of 211 applications.1 Connecting that many with one-to-one zaps becomes a web nobody can maintain.
The "eight islands" problem
Every disconnected tool is an island, and every manual copy between them is a person in a rowboat. The cost isn't just the paddling, it's the trips that get skipped, and the fact that you can never quite trust that everything made it across.
iPaaS vs point-to-point vs an integration hub
Point-to-point scripts: fragile and exponential
Custom scripts between each pair of tools multiply: ten tools can need dozens of brittle connections, each a thing to break.
Zapier-style: fine until volume, edge cases and audit
Great for a handful of simple triggers; strained by volume, transformations, error handling and any need for an audit trail.
A hub: one place, every event traced
One layer, every event logged, new bridges added by configuration, and the whole flow visible in one place.
What good integration looks like
An event enters once and fans out: a booking lands and within seconds there's a contact in the CRM, an invoice in accounting, a slot held in the calendar and a target in marketing. Each hop is transformed on the way and carries its trail. New tools slot into the hub the day they arrive instead of becoming the next island.
"No glue scripts, no agency invoices, no fragile zaps. Each tool emits the events it already knows about; the hub forwards each one to every system that should hear it, and every event carries its trail."

What changes
The team stops copying. A booking lands once and everything updates. New tools slot in the day they arrive. An integration hub often sits alongside a cross-system sync engine for two-way records, a master data hub for golden records, and a legacy bridge for the old systems. It's the connective tissue of the automation pillar.
Frequently asked questions
- What is an integration platform (iPaaS)?
- An integration platform is a central layer that connects your applications, listens for events, transforms data between them, and routes each event to every system that should react, replacing one-off scripts and manual copying.
- What’s the difference between an integration hub and Zapier?
- Zapier wires one trigger to one action, which works for a handful of simple flows. An integration hub centralises all connections, handles transformation, error handling and audit, and scales to many systems without becoming a web of brittle zaps.
- When do you outgrow point-to-point integrations?
- When the number of connections starts multiplying, when flows need transformation or error handling, or when you need an audit trail. At that point a central hub is cheaper to run than a growing tangle of scripts.
- Can it connect a legacy system?
- Yes, typically via a legacy bridge that reads and writes through the old system’s existing surface (a database, a file, an API wrapper), so it can join the modern event flow without a rewrite.
