Why Your Team Doesn't Need 3 Separate Tools for PM, Chat, and Time Tracking

If your team is like most, your workday looks something like this: open Asana to check tasks, switch to Slack to discuss them, hop into Harvest to log time, then back to Asana to update progress. Repeat 40 times a day.

You’re not alone. A 2024 survey by Gartner found that knowledge workers switch between an average of 9 apps per hour. Each switch costs focus. Each subscription costs money. And the connections between tools — that context that gets lost in translation — costs projects.

The Hidden Tax of Context Switching

There’s a well-known statistic from the University of California, Irvine: it takes an average of 23 minutes to fully refocus after an interruption. Every time your developer closes Asana to check a Slack notification, that’s not just 2 minutes lost — it’s potentially 23.

Now multiply that by your team size, and by the dozens of cross-tool switches that happen daily. The productivity loss is staggering.

But there’s a subtler cost too: the loss of context. When a conversation about a task happens in Slack, that context doesn’t live next to the task. Future team members (or future you) can’t reconstruct the decision. You end up with a project management system full of tasks with no context, and a Slack history that holds all the real decisions but is impossible to search meaningfully.

The Real Financial Cost

Let’s do the math that most teams never sit down to do:

Tool	Per seat/month
Asana (Starter)	$11
Slack (Pro)	$7.25
Harvest (Pro)	$10.80
Total	$29.05

For a team of 10, that’s $290/month — $3,480/year — for three tools that don’t talk to each other.

The Slack bill alone is often shocking when someone actually looks at it. And Harvest’s per-seat pricing adds up fast for agencies trying to track time across multiple clients.

What Integrated Actually Means

“Integrated” is an overused word in SaaS. Most tools that claim to integrate mean they have a Zapier connection, or a webhook that sends a notification somewhere.

Real integration means the tools share context natively. When you log time against a task, that time lives on the task. When you message your teammate about a project, that message is scoped to the project — not floating in a general channel where it’ll be buried by weekend memes within 48 hours.

It also means one login. One notification stream. One place to search. One billing line item.

The Objections (and Honest Answers)

“But everyone already uses Slack.”

Yes, and everyone used Blackberry until they didn’t. The inertia is real — switching communication tools is genuinely hard. But the teams that do it report that the initial friction disappears within two weeks, and what they get in return (context-linked conversations, no separate subscription) lasts indefinitely.

“We’ve invested heavily in customizing Asana.”

Sunk cost fallacy. The question isn’t what you’ve spent, it’s what gives your team the best workflow going forward. Most Asana customizations are replicable in any modern PM tool in an afternoon.

“Our clients use Harvest invoices.”

Any decent invoicing tool can produce professional invoices. The format change takes one email to your client to explain.

What to Look For in a Replacement

If you’re evaluating alternatives, here’s what matters:

Native chat — not an integration, not a widget. First-class messaging tied to tasks and projects.
Time tracking at the task level — click a timer on a task, not a separate app.
Invoice generation from time logs — the whole point of tracking time for client work is generating accurate invoices without manual data entry.
Reasonable per-seat pricing — the combined cost of 3 tools should feel like a lot. The replacement should feel like relief.

The Bottom Line

Three separate tools for PM, chat, and time tracking made sense in 2015 when no single tool did all three well. That’s no longer the case.

The question for your team isn’t whether the tools you have work — they do. The question is whether the overhead of maintaining three separate contexts, three separate billing relationships, and the cognitive tax of constant switching is worth the marginal feature differences.

For most teams, the answer is no.
