Example US Agency Automation Stack in 2026

TSA Verdict: This agency automation stack audit guide exists because the $395 to $975 monthly range above is not hypothetical. It is a documented pattern from US agencies that added tools incrementally without ever reviewing what the previous tool already covered. The audit framework in this article identifies overlap, zombie subscriptions, credit waste, and misallocated spend in five structured steps.

Most US agencies do not have an automation tool problem. They have an automation sprawl problem. The average 10-person marketing agency pays for Zapier, Make.com, a CRM automation module, a separate email tool with its own sequences, and ClickUp automations running in parallel. Three of those tools are doing the same job. The automation stack audit in this guide identifies the overlaps, the credit waste, and the tools you can cancel this month without breaking anything.

The agency automation stack audit is not an annual exercise. It is a quarterly habit that pays for itself in the first 30 minutes of the first session. The specific waste patterns this guide identifies across Zapier, Make.com, Clay, ClickUp, and CRM platforms are documented across TSA’s testing of these tools on paid plans. Every dollar of waste described below has been verified against actual billing data and platform documentation.

This automation stack audit guide is part of TSA’s broader evaluation of the best workflow automation tools for US agencies.

Why US Agency Automation Stacks Accumulate Waste

Understanding the mechanism of waste is the first step in the automation stack audit process.

Pattern 1: Parallel platform adoption without decommissioning.

A US agency starts on Zapier in 2023. A new ops hire joins in 2024 and prefers Make.com. Both tools keep running. Two years later, 8 workflows run on Zapier and 12 run on Make.com. No one migrated the Zapier workflows to Make.com. No one cancelled Zapier. The agency pays $19.99/month for Zapier Professional plus $9/month for Make.com Core. Combined: $348/year. Potential saving from consolidating to Make.com alone: $239.88/year.

Pattern 2: CRM automation modules running alongside standalone automation tools.

HubSpot Starter includes workflow automation. HubSpot Professional includes 300 workflow actions per month. ClickUp Business includes 5,000 automation actions per month. Zapier Professional includes 750 tasks per month. A US agency paying for all three has automation capability in three separate places, each handling a slightly different set of triggers because no one mapped which tool handles which workflow. The result: duplicate notifications fire, contacts receive two emails from the same event, and CRM data updates lag because three tools are writing to the same record in different sequences.

Pattern 3: Credit-consuming tools running on unoptimized configurations.

Make.com charges per module execution. A Make.com scenario polling a Gmail inbox every 15 minutes generates 2,880 polling executions per month before processing a single email. On Core’s 10,000-credit allocation, that single misconfigured trigger consumes 29 percent of the monthly budget on empty checks. A Zapier Zap with a filter step placed after two action steps runs those actions on every trigger, consuming tasks on records that should have been filtered out before any action fired. Clay tables with auto-run enrichment columns firing on every row regardless of domain validity burn Data Credits on disposable email addresses, personal Gmail addresses, and defunct company domains.

Pattern 4: Zombie subscriptions from departed team members or closed projects.

A US agency project manager set up a Zapier account in 2024 to automate a specific client campaign. The campaign ended. The project manager left. The Zapier subscription renewed automatically at $19.99/month for 18 months before anyone noticed. At the current documented average of 42 SaaS tools for smaller firms, at least 2 to 3 subscriptions at any given time fall into the zombie category: active billing, zero active workflows.

The 5-Step Automation Stack Audit

Step 1: Pull Every Subscription from Every Payment Source

The automation stack audit starts with a complete subscription inventory, not with the tools you remember using.

Pull the last 3 months of statements from every credit card, PayPal account, and bank account that has ever paid for a SaaS tool. Include the company card, any personal cards with business reimbursements, and any accounts held by departed team members that are still active.

For each line item, create a row in a Google Sheet with:

Columns: Tool Name | Monthly Cost | Annual Cost | Payment Source
         | Who Set It Up | Last Login Date | Active Workflows Count
         | Primary Function | Other Tools That Do This Job

Do not filter yet. The goal of Step 1 is a complete list without judgment. Judgment comes in Step 3.

Common hidden subscriptions US agencies miss in the first pull:

Zapier accounts created by individual team members on personal emails before the company account existed.

Make.com scenarios created by a freelancer or contractor whose login is now the only owner of those automations.

Clay tables set up for a specific outbound campaign that ended but whose monthly credit charge continues.

Apollo.io seats for team members who have since moved to LinkedIn Sales Navigator but whose Apollo seat was never cancelled.

NeverBounce or ZeroBounce verification subscriptions set up alongside Apollo or Clay without checking whether the primary tool already handles verification.

Step 2: Map Every Active Workflow to Its Platform

For each automation tool in the inventory, document every active workflow it runs. This step takes 2 to 4 hours for a typical 10-person US agency with 2 to 3 automation platforms.

For each workflow, record:

Workflow Name | Platform | Trigger | Action Steps | Monthly Run Count
| What Breaks If This Stops | Equivalent Capability in Other Platform

The “Equivalent Capability in Other Platform” column is where the automation stack audit starts generating savings. When a Zapier workflow that sends a Slack notification on a new HubSpot contact also exists as a HubSpot workflow in the CRM, that is a documented overlap. One of them is redundant.

The five overlap patterns TSA finds most commonly in US agency automation stack audits:

CRM workflow and Zapier Zap triggering on the same event. HubSpot and Salesforce both include native workflow automation. Many US agencies also have Zapier Zaps watching the same CRM events. Both fire. The Slack message goes twice. The spreadsheet row is duplicated. The Zapier task is consumed for a workflow the CRM was already handling for free.

ClickUp automation and Zapier Zap creating the same notification. ClickUp Business includes 5,000 automation actions per month. Many agencies also have Zapier watching ClickUp status changes and posting to Slack. ClickUp’s native Slack integration handles this without consuming Zapier tasks. The Zapier Zap is redundant.

Make.com scenario and Zapier Zap running the same data sync. When both Make.com and Zapier are in the stack, data syncs between the same two apps sometimes exist on both platforms because different team members built them at different times. The sync runs twice, creating duplicate records.

Email marketing automation and CRM sequences both enrolling the same contacts. Mailchimp, ActiveCampaign, or a similar tool running enrollment-based sequences for the same trigger event that HubSpot workflows also cover. The contact receives two welcome emails. The unsubscribe from one does not propagate to the other.

Clay enrichment running on raw unfiltered imports. Clay tables auto-enriching every row including personal email addresses, Gmail domains, defunct company URLs, and contacts already in the CRM. Credits burning on records that a pre-filter layer would have eliminated before enrichment costs were incurred.

Step 3: Score Every Tool Across Four Dimensions

Apply this scoring framework to every tool in the inventory. Score each dimension from 1 to 3.

Dimension 1 — Utilization
1: Less than 40% of active workflows use this tool
2: 40 to 75% utilization
3: Above 75% of active workflows depend on this tool

Dimension 2 — Overlap
1: At least 2 other tools in the stack cover identical functionality
2: 1 other tool partially covers this function
3: No other tool in the stack covers this function

Dimension 3 — Migration Effort
1: Workflows could be rebuilt in another existing tool in under 4 hours
2: Migration requires 4 to 20 hours
3: Migration requires 20 plus hours or custom development

Dimension 4 — Cost Efficiency
1: Cost per active workflow exceeds $20/month
2: Cost per active workflow is $5 to $20/month
3: Cost per active workflow is under $5/month

Tools scoring 4 to 6 across all four dimensions are cancellation candidates. Tools scoring 7 to 9 are consolidation candidates. Tools scoring 10 to 12 are keepers.

Step 4: Identify and Fix the Credit Waste

This step is specific to tools that charge per execution, per credit, or per task. It does not apply to flat-fee tools.

For Zapier (per-task billing):

Open Zapier’s billing dashboard and export the task usage breakdown by Zap for the last 90 days. Sort by tasks consumed descending. Identify the top 5 task consumers.

For each high-consumption Zap, locate the filter step. If the filter sits after any action step, move it to immediately after the trigger. This single fix reduces task consumption by 15 to 35 percent on most US agency Zap libraries.

Check whether any high-consumption Zaps duplicate workflows already running in HubSpot, ClickUp, or another tool in the stack. If they do, route through the native automation and turn off the Zap.

Expected saving: 15 to 40 percent reduction in monthly Zapier task consumption without changing any workflow output.

For the full Zapier cost breakdown including the multi-step task audit at three US agency sizes, see the TSA Zapier pricing guide.

For Make.com (per-credit billing):

Open Make.com’s operations dashboard and identify every scenario using a scheduled polling trigger rather than a webhook trigger. Polling triggers fire on a schedule regardless of whether new data exists. A polling scenario checking for new data every 5 minutes fires 8,640 times per month. The same scenario on a webhook fires only when new data arrives.

Convert every polling trigger where the source app supports webhooks (HubSpot, Stripe, Typeform, Shopify, ClickUp, Slack, Gmail with Pub/Sub) to webhook triggers.

Expected saving: 20 to 60 percent reduction in monthly Make.com credit consumption depending on the number of polling scenarios currently active.

For the complete Make.com plan comparison including when Teams or Enterprise replaces Core on credit volume, see the TSA Make.com Teams vs Enterprise guide.

For Clay (per-Data Credit billing):

Open the Clay workspace and identify every table with auto-run enrichment columns enabled. For each auto-run table, check the input data: does it include Gmail or other personal email domains? Disposable email domains? Existing CRM contacts that are already enriched? Blank domain fields?

Each of these record types consumes Data Credits on enrichment attempts that produce zero usable output. Add a pre-filter formula column that checks for personal domains, blank emails, and existing CRM contacts before any enrichment column fires.

Expected saving: 25 to 45 percent reduction in monthly Clay Data Credit consumption on tables receiving mixed-quality input data.

For the complete Clay credit consumption model at three agency enrichment volumes, see the TSA Clay.com pricing guide.

The original cost model: what these fixes save a typical US agency

Before automation stack audit (typical 10-person US agency):

Zapier Professional (750 tasks, consistently in overage):
  Base: $19.99/mo
  Average overage (250 tasks at $0.20): $50/mo
  Monthly total: $69.99

Make.com Core (10,000 credits, polling triggers active):
  Base: $9/mo
  Polling waste (estimated 3,000 credits/mo on empty polls): 30% of plan
  Effective cost per useful operation: inflated

Clay Launch (2,500 credits, unfiltered table auto-run):
  Base: $167/mo
  Estimated 40% of credits on invalid/personal domains: $66.80 wasted
  Effective cost per usable enriched contact: inflated

After automation stack audit:

Zapier: Filter step fixes reduce task consumption by 30%
  New monthly: $19.99 (no overage)
  Monthly saving: $50

Make.com: Polling to webhook conversion reduces credit consumption by 50%
  Credit usage drops from 10,000 to 5,000
  Still on Core plan — no change
  Effective cost per useful operation: halved

Clay: Pre-filter layer eliminates 35% of bad input records before enrichment
  Monthly saving: $58.45 (35% of $167)
  Delivers same number of usable enriched contacts

Total monthly saving from optimization alone (no cancellations): $108.45
Annual saving: $1,301.40

Step 5: Cancel, Consolidate, or Renegotiate

With the overlap map and the scoring results from Steps 2 and 3, three decisions are now available.

Cancel: Tools scoring 4 to 6 with no active workflows that cannot be served by existing tools. Standard cancellation cadence: cancel at the next billing anniversary, not mid-cycle. Exception: monthly billed tools with no annual commitment where immediate cancellation recovers cost this month.

Consolidate: Two tools doing the same job where one is clearly stronger on the score. Rebuild the workflows from the weaker tool in the stronger tool, then cancel the weaker subscription after 30 days of parallel running to confirm nothing breaks.

Renegotiate: Tools that score well but are approaching the end of their annual contract. Before auto-renewal, contact the account manager or support team with a competitor quote. Documented renewal discounts of 15 to 30 percent are achievable on Zapier, Clay, and Apollo.io with a competitive quote in hand and a credible willingness to migrate.

FAQ

How much can a US agency save from an automation stack audit?

Based on documented agency implementations, the typical US 10-person agency recovers $150 to $400 per month from a first-pass automation stack audit. Savings come from three sources: fixing credit waste on misconfigured tools (Zapier filter placement, Make.com polling triggers, Clay unfiltered tables) saves $80 to $180 per month without cancelling anything. Eliminating overlap between tools doing the same job (CRM automation running alongside Zapier, ClickUp automations duplicating Slack notifications) saves $50 to $150 per month. Cancelling zombie subscriptions with zero active usage saves the full subscription cost of each discovered tool.

What is the first thing to check in an automation stack audit?

Pull every subscription from every payment source before opening any tool dashboard. Credit cards held by departed team members, personal cards with business reimbursements, and accounts created under individual email addresses are the most common sources of zombie subscriptions that no one has visibility into. The subscription inventory is the foundation of the automation stack audit. Skipping it and going directly to tool evaluation misses 20 to 30 percent of the actual spend.

How often should a US agency run an automation stack audit?

Quarterly is the correct cadence. Annual audits miss the zombie subscriptions and tool additions that accumulate between reviews. Monthly is unnecessary overhead for most agencies. A quarterly automation stack audit takes 2 to 4 hours for a typical 10 to 15 person US agency and generates enough savings to pay for the time invested many times over across the year.

What is the most common waste pattern in US agency automation stacks?

CRM automation modules running in parallel with standalone automation tools is the most commonly documented waste pattern. HubSpot, Salesforce, and ActiveCampaign all include workflow automation. Many US agencies also pay for Zapier or Make.com running the same trigger-action sequences the CRM already handles natively. The CRM automation runs first, fires the intended action, and then the Zapier Zap fires a second time on the same event. The result is duplicate notifications, duplicate CRM record updates, and Zapier tasks consumed for workflows the CRM was already executing for free.

How do you identify zombie subscriptions in an automation stack audit?

Pull 90 days of statements from every payment source and list every recurring SaaS charge. For each tool, check the last login date and the number of active workflows or active users. Any tool where the last login is more than 60 days ago and there are no active workflows is a zombie subscription candidate. Tools where the only person with admin credentials has left the company are immediate cancellation candidates regardless of login date, as those tools represent both wasted spend and a security risk.

What tools are most commonly found as redundant in US agency automation stack audits?

Four tools appear most frequently as redundant in automation stack audits for US agencies. Zapier, when Make.com is also in the stack and covers all required integrations. Standalone email marketing platforms (Mailchimp, Klaviyo at entry tiers) when the CRM already includes email sequence automation at the same or higher capability. Apollo.io seats assigned to account executives or managers who do not prospect and use Apollo only for CRM data viewing, which is available at lower or zero cost. And Clay tables that duplicate Apollo or HubSpot enrichment that was already being run elsewhere in the stack on the same contact data.
