A MarTech audit is a structured review of your marketing tools, their costs and usage, and the way data moves between them. It helps your team decide what to keep, improve, consolidate or replace without breaking lead capture, sales handoffs or reporting.
A useful audit evaluates the operating system, not just the software list. A tool may work correctly while an integration drops a field, two automations compete, or nobody owns a failed handoff.
This checklist is for B2B marketing operations managers, RevOps teams, marketing leaders and founders. You can use the tables and review steps directly; no download is required.
When a MarTech stack audit is useful
Start with an operational question, such as why leads arrive without owners or whether another platform is actually needed. Warning signs include:
- Several tools perform similar tasks, but nobody can explain which process needs each one.
- Teams export and re-import spreadsheets to connect systems that should exchange data.
- Forms capture leads, but source fields, consent status or ownership are missing in the CRM.
- Sync errors recur, or a connection still relies on an account owned by someone who has left.
- Reports disagree and the team cannot trace their definitions or source data.
- Renewals approach without a clear owner, usage evidence or a plan for dependent processes.
- A new tool is proposed before the limits of the current configuration are understood.
These are reasons to investigate, not proof that a platform needs replacing. Differences in reporting can also be expected; the GA4 and HubSpot conversion discrepancy guide explains how to separate those differences from tracking problems.
Separate cost optimization from a technical integration audit
Cost optimization asks whether licenses, tiers and contracts match business needs. A technical integration audit asks whether connections, field mappings, automation and failure handling work as intended. They inform each other, but one cannot substitute for the other.
| Review | Evidence to collect | Decision it supports |
|---|---|---|
| Cost and utilization | Contracts, billing basis, renewal terms, assigned licenses, activity and required features | Adjust seats or tiers; investigate unused or overlapping capability |
| Integration and operations | Data-flow maps, sync logs, field mappings, permissions and controlled test results | Repair handoffs; reduce operational risk; assess migration dependencies |
Low login activity does not mean low value. A connector may run unattended and support every lead handoff. High usage does not prove good value either: repeated manual work can inflate activity.
A practical MarTech audit sequence
1. Inventory tools and identify owners
- List CRM, marketing automation, forms, analytics, tag management, reporting and integration tools. Include spreadsheets, scripts and agency-managed accounts used in live processes.
- Record a business owner and a technical administrator. Flag missing ownership rather than assigning responsibility by assumption.
- Identify the accounts, workspaces and environments in scope. Agree the access needed before inspecting configuration.
2. Map functions, costs, renewal dates and usage
- Describe the business task each tool supports and the features actually required.
- Record currency, billing period, committed cost, usage charges, renewal date and cancellation notice. Keep unknown values marked as unknown.
- Compare purchased capacity with relevant usage: active seats, workflow runs, managed contacts or processed records. Check whether the observation period reflects normal business activity.
- Ask users about adoption barriers and workarounds. Separate an unused feature from a feature the business does not need.
3. Review integrations and data flows
- For each connection, record the source, destination, direction, trigger, sync timing and record types.
- Document matching keys, field mappings and the authoritative system for critical fields such as lifecycle stage, owner and consent status.
- Inspect permissions, authentication ownership, recent errors, retry behavior and failure alerts. Confirm what happens if a record cannot be matched.
- Trace a controlled test record through the important handoffs. A connected status alone does not prove the right data arrives.
For forms, use the B2B form-to-CRM tracking QA checklist to test submission, record creation, field capture, routing and measurement together.
4. Identify overlap, manual work and data-quality problems
- Map capabilities to processes. Two tools offering forms are not necessarily redundant if they serve different requirements.
- Find duplicate writes to critical properties, repeated exports, conflicting definitions and records without reliable matching keys.
- Record evidence for each issue: configuration, log entry, test result or a documented manual step. Separate confirmed findings from checks still needed.
- For HubSpot-specific data, lifecycle and workflow checks, use the HubSpot Portal Audit Checklist.
5. Evaluate business value and operational risk
- Connect each tool to a business task and explain what would stop working if it were unavailable.
- Assess lead-loss risk, reporting reliability, access control and dependence on undocumented processes.
- Check whether required data can be exported and retained appropriately, and whether a replacement can support essential features and permissions.
- Record confidence in the assessment. Missing evidence is a reason to investigate, not a reason to cancel.
6. Prioritize keep, improve, consolidate or replace decisions
- Keep: the tool meets a clear need and its important processes are validated.
- Improve: the tool fits, but configuration, ownership, adoption or integrations need attention.
- Consolidate: overlapping functions can move to an existing tool after feature and dependency checks.
- Replace: essential requirements cannot be met reliably; validate an alternative and plan the migration before committing.
For each decision, name the owner, evidence, next action and acceptance criteria. Do not disable a tool until its dependent forms, automations, data and reporting have a tested destination.
Build a usable audit inventory
Use one row per tool or separately managed workspace. The table below is a fill-in template, not a completed audit. Add renewal and notice dates in the cost field, and link to a separate data-flow map if dependencies need more detail.
| Tool | Purpose | Owner | Integration dependencies | Cost | Utilization | Identified risk |
|---|---|---|---|---|---|---|
| CRM — enter platform | Records, lifecycle and sales handoff | Business owner / administrator | Inbound sources; outbound systems; matching keys | Currency, billing period, renewal and notice date | Active seats; essential processes | Evidence of field, access or routing issues |
| Marketing automation — enter platform | Qualification and follow-up | Process owner / administrator | CRM sync; forms; consent fields | Tier, contact or usage charges; renewal | Active workflows; required features | Evidence of conflicting updates or sync failures |
| Forms — enter platform | Capture and route inquiries | Conversion owner / administrator | Website; CRM connector; event triggers | Subscription or bundled cost; renewal | Live forms; successful submissions | Evidence of mapping gaps or failed handoffs |
| Analytics and tag management — enter tools | Events and reporting | Measurement owner / administrator | Website; consent controls; reporting exports | License and support costs, if applicable | Required events and reports used | Evidence of duplicate events or unclear definitions |
Example assessment matrix — hypothetical
Every entry below is hypothetical. These are examples of evidence-based decisions, not client findings, benchmarks or savings claims.
| Hypothetical finding | Evidence to seek | Proposed decision | Dependency / validation |
|---|---|---|---|
| CRM supports the sales process, but owner assignment is inconsistent | Routing rules, record history and controlled lead tests | Improve the handoff, not replace the CRM | Agree ownership rules; test normal and fallback paths |
| Two tools send follow-up emails for the same inquiry | Triggers, audience exclusions and delivery history | Consolidate if one tool meets the requirements | Check consent, templates and suppression; test before switching |
| A form connector drops a qualification field | Submission payload, mapping and destination record | Improve the integration | Confirm field types and accepted values; test new and existing contacts |
| A form tool cannot support an essential routing requirement | Requirement review and a controlled capability test | Evaluate replacement | Validate the alternative; migrate forms and tracking; retain rollback |
Prioritize findings by impact, effort and dependencies
Impact describes the business process at risk and who is affected. Effort includes configuration, migration, testing, training and ongoing maintenance. Dependencies identify what must be resolved before a change is safe.
- Contain active failures first. If testing confirms submissions are being lost, preserve them in an approved fallback and assign someone to reconcile affected records.
- Resolve prerequisites. Agree field ownership and lifecycle definitions before rewriting automations that depend on them.
- Sequence improvements. A low-effort mapping fix may precede a broader consolidation, but neither should bypass testing.
- Plan contract decisions. Review renewals early enough to test alternatives and understand notice terms. A deadline alone is not evidence that removal is safe.
There is no universal priority score. An inexpensive connector can be more critical than a costly reporting tool. When impact or effort is uncertain, schedule a targeted test before ranking the fix.
Worked example: CRM, automation, forms and analytics
Hypothetical example — not a client engagement. A B2B team uses HubSpot CRM, a separate marketing automation system, website forms and GA4 through Google Tag Manager. Marketing reports form submissions, while sales reports that some inquiry records lack qualification details.
- Map the intended journey. Form submission → connector → CRM record → automation → sales owner. Separately map the browser event sent to GA4, subject to consent.
- Run a controlled test. Use an approved test identity, record the time and submitted fields, and inspect the form response, connector logs, CRM record and automation history. Avoid sending personal contact data to analytics.
- Compare evidence with intent. Suppose the form stores company size, but the connector does not map it to the CRM. The automation requires that field, so the record does not enter the intended routing branch. The GA4 event still fires because it does not depend on CRM delivery.
- Recommend a focused improvement. Confirm the destination property and accepted values, repair the mapping, and agree an exception path for incomplete records. Assess affected records before any backfill; historical automation may need separate controls.
- Validate before closing. Test new and existing contacts, missing-field and connector-failure paths. Confirm correct field values, intended enrollment, ownership and alerts. Check that the browser event fires as intended without duplicating it.
In this example, the finding supports improving a handoff, not purchasing another tool. It also shows why analytics activity does not prove that a lead reached sales. A technical integration audit explains the failure; the cost review can then assess overlap against validated requirements.
Turn the checklist into a decision record
A completed audit should leave your team with a tool inventory, a map of critical data flows, evidence-backed findings and a sequenced action list. Each proposed change needs an owner and a clear test for success.
If problems cross several tools and teams, a Marketing Operations Systems Review can help assess the wider operating model rather than treating each symptom in isolation.
