How Often Should an Agency Review the Tools It Pays For?

Review your software stack every quarter, tying each tool directly to revenue or hours saved. In that review, identify unused seats, overlapping tools, and subscriptions no one remembers approving. When the math stops working, cancel low-usage tools first, then those whose capabilities your existing stack already covers, and finally anything disconnected from billable work or client delivery.

Why does subscription creep cost agencies more than most businesses?

29% of software spend goes to unused or underused SaaS subscriptions, but agencies face a sharper version of that problem. You already run tight margins on client work. When business units control 81% of total SaaS spend (bassgordon.co.za) and your project managers, designers, and account leads can each sign up for tools independently, no single person tracks the total bill.

50% of all software licenses go unused, costing companies $45 million per month (ramp.com) at enterprise scale, but even a 20-person agency can bleed $2,000 per month on seats tied to former employees, tools bought for one project and kept forever, or apps that seemed necessary during a pitch. 38% of licenses go unused over a 30-day period (backupify.com), and when you're billing 1,800 hours per employee per year, every $20 monthly seat that returns nothing is half an hour of billable work you gave away.

AI tools make it worse. AI spend across all Ramp customers grew 4x year-over-year from February 2025 to February 2026, and many of those purchases happen outside formal procurement because individuals sign up with personal cards and expense them later.

What overlapping tools look like in practice

Three people on your team use three different screenshot tools. Two project management platforms run side by side because one client prefers Asana and another wants Monday. You pay for both Semrush and Ahrefs because someone insisted the backlink data differed, but your team only logs into one of them regularly. You have Slack, Microsoft Teams, and Zoom, and every client call requires clarifying which one to use.

The easiest overlaps to spot are in categories where SaaS vendors compete directly: SEO tools, design collaboration, time tracking, invoicing, analytics dashboards. The hardest are tools that each cover 70% of the same ground but whose 30% differences once justified both subscriptions. Quarterly reviews surface these because you ask, for each tool, "If we canceled this tomorrow, what specific task could we no longer complete?" If the answer overlaps with another tool's answer, one of them should go.

For agencies evaluating technical audits, the free AI-visibility check (/check) can replace paid tools that only look at on-page SEO without addressing whether AI assistants recommend the business when potential clients ask who to hire.

How do you tie each tool to revenue or hours in a quarterly review?

Build a spreadsheet with these columns: tool name, monthly cost, seats purchased, seats active in the last 30 days, department owner, and measurable output. That last column is where the review succeeds or fails. The formula is (Time Saved x Hourly Rate + Revenue Gained) minus Tool Cost, divided by Tool Cost (zeroday-ai.com), but many tools justify themselves through capacity rather than revenue.

A proposal tool that cuts proposal-writing time from four hours to 90 minutes returns three billable hours per proposal. If your team writes 20 proposals per quarter and your average loaded rate is $75 per hour, that tool saves $4,500 per quarter. A $200-per-month tool ($600 per quarter) returns 650% ROI. Document that.

A rank-tracking tool that costs $400 per month but sits unused after the client SEO campaign ended last quarter returns zero. Cancel it.

The tools that survive this math are ones where you can say exactly how many hours they save, which clients depend on them, or how much revenue they help close. ActiScore's pricing (/pricing) is structured specifically so agencies can tie audit scans to client contracts: each scan becomes a deliverable, and if a Growth plan at $199 per month delivers 1,000 scans, you know the cost per client report is 20 cents when you're using the full allocation. The measurable output is client reports delivered, and the revenue tie is whatever you charge for those audits.

What to cancel first

Start with software licenses that often go unused due to employee turnover, role changes, overlapping tools, or applications being installed "just in case" but never actively adopted (blog.invgate.com). Unused seats may represent an opportunity to reduce the next bill (panstag.com), and in most SaaS contracts you can downgrade seat counts at renewal without penalty.

Cancel in this order:

1. Seats for employees who left. With 40 employees leaving every year, if companies want to retain data for at least one year, they'd have to shell out more than $14,000 in unused licenses annually. Export any data tied to those accounts, then remove the seats.

1. Tools no one logged into in 60 days. If usage data shows zero logins across the team, it's not a tool you're going to miss. One exception: tools used seasonally (tax software, end-of-year reporting platforms). Flag those rather than canceling outright.

1. The second tool in any overlapping pair. Pick the one with lower usage or weaker integration with the rest of your stack. According to Ramp's guide on subscription creep, consolidating overlapping tools is one of the fastest ways to cut waste without losing capability.

1. Anything purchased for a single project that ended. If a tool was justified by one client contract and that contract is complete, the tool should go unless another client immediately needs it.

1. Tools whose capabilities your core stack absorbed. When Slack added huddles, some agencies dropped standalone voice-call apps. When Notion added databases, teams canceled Airtable. When the guide (/guide) to technical SEO gets built into your main platform, standalone checkers become redundant.

The tools you keep are the ones that either generate billable work directly, save more hours than they cost, or enable client work you couldn't deliver otherwise. Everything else is overhead pretending to be infrastructure.
