How long does a Tealium implementation take?

It scales with the estate: the phases above are the constant, the calendar is not. A focused single-property build and a multi-brand, multi-domain rollout are different projects - we scope from the discovery audit, not from a template timeline.

Can you take over a half-finished implementation?

Yes - that is a common engagement. It starts with a runtime audit of what actually fires today, then a gap map against the intended architecture, then remediation in priority order.

Do you implement iQ only, or the full Customer Data Hub?

Both. Plenty of estates need governed tag management first and the CDP tier later; the data layer and taxonomy work is identical either way, which is why we build it first.

What does implementation cost?

It depends on scope, which is exactly why we start with a fixed-scope audit rather than a guess - see the pricing guide for how platform and implementation costs form.

Tealium Implementation Services - Enterprise Deployment, Governed

What an enterprise implementation includes

Our implementations run architecture-first, in phases that build on each other:

Phase	What gets built
Discovery and audit	Runtime inventory of current tracking, stakeholder reporting requirements, integration map, identity sources
Data layer design	The universal data object specification - the contract every tag and connector reads from
Event taxonomy	Named, versioned event specification with owners; conversion definitions agreed across teams before anything fires
Tealium iQ build	Profiles, environments, load rules, extensions, tag templates - built to the spec, not ad hoc
Server-side collection	EventStream specification and connector routing where client-side collection is not durable enough
Identity and audiences	Visitor stitching logic and AudienceStream attributes where the CDP tier is licensed
QA and runtime verification	Every claim in the handoff verified from the wire - captured payloads, not configuration screenshots

The data layer decides everything

Most failed implementations we audit share one root cause: tags were built first and the data layer was improvised underneath them. Every subsequent integration then invents its own reading of the page, and reporting drift becomes structural. We write the data layer specification before the first tag is touched, and every load rule, extension, and connector maps to it. That single discipline is most of what "enterprise-grade" means in practice.

Implementing into an existing estate

Greenfield implementations are rare. The usual reality is an existing container - GTM, Adobe Launch, a legacy Tealium profile - carrying years of accumulated tags. We implement by parallel run: the new architecture collects alongside the old, numbers are reconciled, and cutover happens per-platform once the delta is explained. See the migration guides for direction-specific playbooks.

Common failure modes we are hired to prevent

Taxonomy drift - teams deploy events independently and names stop meaning the same thing across platforms.
The unowned profile - iQ becomes a graveyard of load rules nobody dares delete.
Identity improvisation - visitor stitching rules that were never written down and cannot be validated.
Connector sprawl - destinations added for convenience, each one an unreviewed data recipient.

The method: every deliverable claim is verified at runtime - captured from the wire, not read off a configuration screen. Anything we could not measure is labeled as an assumption in the deliverable itself.
