All-in-one agency software or separate tools: how to decide

The case for one suite is usually made on price, and price is the weakest part of it. The larger costs of a stack of separate tools don't show up on an invoice: seats nobody uses, the same client typed into six systems, and people switching between windows all day.

Both have been measured. Zylo's 2026 SaaS Management Index puts the share of SaaS licenses that go unused at 46%. Its sample is large companies with hundreds of apps, so an agency's numbers will be smaller, but the pattern holds at any size. And in a study published by Harvard Business Review in 2022, workers at three large companies switched between apps nearly 1,200 times a day and spent just under four hours a week reorienting after those switches.

For an agency, the handoff cost is the one that bites. A client's name, budget and dates typed into a project tool, a time tracker, a reporting tool and an invoicing tool each drift a little, and someone spends Monday morning reconciling them. Those hours are a real cost, and they never appear on a pricing page.

Before comparing anyone's pricing page, get your own numbers. You need the card statement, the admin pages of each tool and an hour.

1. List every tool you pay for, with its monthly cost, the number of seats, who owns it and when it renews. The free stack audit turns that list into annual spend, cost per person and the renewals coming up, in your browser, with no account.
2. Mark the seats that were used in the last 30 days. Most admin pages show last sign-in.
3. Write the job each tool does: reporting, projects, time, scheduling, research, files, approvals. Two tools on one job is an overlap; one tool on no job is a cancellation.
4. Count the handoffs: how many systems does a new client's name get typed into before the first invoice? Each one is a place where numbers drift apart.
5. Divide the monthly total by the number of people. That cost per person is the number to compare, not the price of any single tool.

Example team: 12 people and 8 clients, on annual billing where the vendor shows it, at list prices read on 19 October 2026. monday.com Pro at $19 a seat is $228 a month. Harvest Teams at $9 a seat is $108. Float Pro at $12 per scheduled person is $144. AgencyAnalytics Core at $20 per client is $160. Notion Business at $20 a member is $240. Semrush's Pro+ plan is $248.17 a month billed annually.

That is about $1,130 a month, or $94 per person, for six tools, before any AI assistant, design, proofing or client portal. Prices change and plans get renamed, so check each vendor's page before you put a figure in a proposal. Then compare that total, and your count of unused seats and handoffs, with a suite's price for the same team on its pricing page.

A suite isn't always the right answer, and saying so is part of making the decision honestly. Keep separate tools when:

• One job is your whole business. An SEO shop needs the deepest SEO tool it can buy, not the SEO corner of a suite.
• A client requires a specific tool and pays for it.
• Your stack is already connected, cost-effective and owned by someone who keeps it that way.
• The suite is weaker at your core job than the tool it would replace. Test that job first, with your own data.

Move one job at a time, starting with the one that causes the most retyping, usually projects and time or client reporting. Run the old tool and the new one side by side for one billing cycle, with real clients, so the team finds the gaps before the old data is gone. Export everything you might need later: past reports, timesheets, invoices.

Cancel at the renewal date, not before. The list from your count already has every date, and most annual plans don't refund the unused months, so switching a week before a renewal saves a full year while switching a week after wastes one. Tell the clients who see a report or a portal before anything changes on their side.

Whichever way you decide, someone has to own the list. In , every tool has an owner, seats, cost and a renewal date, renewals alert at 120, 90, 60 and 30 days, and a tool's cost can be split across the clients it serves, so it reaches each client's margin in . Two limits: there is no bank or card connection, so tools are entered or imported from a CSV, and seat usage from Google Workspace is still rolling out (a CSV seat upload works today).
