# Managed integration partner vs iPaaS (Zapier, Make, Boomi)

*vs iPaaS (Zapier, Make, Boomi)*

**In short:** iPaaS platforms are excellent for simple, stable connections between mainstream SaaS tools that your team is happy to own. A managed integration partner is the right model when the integration carries real business logic, moves high volumes, needs an SLA, or has to keep running for years without anyone internally taking responsibility for it. The dividing line is not the tool - it is who owns the outcome.

## Where iPaaS fits

iPaaS platforms - Zapier, Make, Boomi and similar tools - are self-service. You configure them, you run them, and you support them. For simple, stable connections between mainstream SaaS platforms, that is exactly the right amount of tooling. If a marketing form needs to drop a lead into a CRM, or a signed document should notify a channel, an iPaaS tool will do it in an afternoon and cost very little.

That model works because the integration is low-stakes and low-logic. Nobody needs an SLA on it, the data shapes are simple, and if it breaks for a day the business absorbs it.

## Where a managed partner fits differently

A managed integration partner is not a tool. We design the data flows and the business logic in the middle, build the integration on cloud-native AWS infrastructure that is fully EU-hosted, and then operate it permanently under contract. Monitoring, alerting, incident response, and upstream API change management are our responsibility, not a task on your team's backlog.

The difference is ownership. With iPaaS, the integration is yours to run the moment it goes live. With a partner, a named owner is accountable for keeping it up and correct, and for fixing it when a vendor changes their API.

## Side by side

| Dimension | iPaaS (Zapier, Make, Boomi) | Managed integration partner |
| --- | --- | --- |
| Who operates it | Your team | The partner, under contract |
| Business logic | Simple mapping, limited branching | Custom deduplication, enrichment, conditional routing |
| Data volume | Fine for low volume; task-priced at scale | Built for high volume without per-task pricing |
| Reliability | Best-effort, no SLA | Up to 99.9% pipeline availability SLA |
| Delivery guarantees | Retries; duplicates possible | Source deduplication and destination idempotency for exactly-once delivery |
| Upstream API changes | Your team notices and fixes | Proactively monitored and fixed by the partner |
| When it breaks | You diagnose it | Named owner and incident response |
| Hosting and compliance | Depends on vendor and region | Cloud-native AWS, fully EU-hosted, DPA / AVV signed |
| Exit | Rebuild elsewhere | Infrastructure-as-code and documentation handed over |

## When iPaaS is the right choice

Be honest about the integration in front of you. If it connects two mainstream tools, carries little business logic, moves modest volume, and your team is happy to keep an eye on it, an iPaaS tool is the better choice. It is faster to stand up and cheaper to run, and adding a partner would be over-engineering.

Most integrations are like this. We will tell you when yours is.

## When a managed integration partner is the right choice

The economics shift when the integration matters. A managed model earns its place when failure has a measurable cost - revenue, compliance, or a customer-facing process; when there is real logic in the middle that an automation tool cannot cleanly express; when the upstream API is volatile or rate-limited; when no internal team wants permanent responsibility; and when the integration will live for years rather than weeks.

If most of those apply, a self-service tool becomes a liability that quietly consumes engineering attention. That is the point at which designing it properly once and handing operations to a partner is the cheaper path.

## Frequently asked questions

### Is a managed integration partner just an agency that resells Zapier?

No. We design the data flows and business logic from scratch and run them on cloud-native AWS infrastructure that we build and operate. There is no third-party automation tool in the middle that you would need a separate subscription for, and no shared multi-tenant runtime whose limits you inherit. You own the resulting implementation.

### We already pay for an iPaaS. Why would we add a partner?

You would not run both for the same integration. The question is whether a specific integration fits the self-service model. If your team is comfortably operating it on iPaaS and it rarely breaks, keep it there. If it keeps failing quietly, needs custom logic the tool cannot express, or has become a job nobody wants to own, that is the integration to move to a managed model.

### Can iPaaS tools not handle high volumes and complex logic?

They can handle a surprising amount, but you pay for it in operational overhead: task-based pricing that scales with volume, timeouts on long-running steps, and logic spread across dozens of connected steps that only the person who built it understands. At a certain point the maintenance burden outweighs the convenience, and a purpose-built pipeline with an owner is cheaper to run.

### What happens when the upstream vendor changes their API?

On a self-service iPaaS, a breaking change usually surfaces as a silent failure that someone on your team has to notice, diagnose, and fix. Under a managed contract, upstream API monitoring and change management are our responsibility. On the Business Critical and Enterprise tiers we track vendor API changes for you and fix the pipeline before your data is affected.
