It's 11 PM. Your phone buzzes. A client is furious — their website has been down for 4 hours and you had no idea. Their customers noticed before you did. Now you're firefighting at midnight, apologizing, and hoping they don't leave.
Sound familiar? Most web agencies offer "maintenance" that's really just updates and backups. No monitoring. No proactive alerts. They find out about outages when the client calls angry.
Website monitoring for agencies is the practice of continuously tracking every client's website uptime, SSL status, and visual integrity — and turning that capability into a paid, recurring service. It's the single highest-margin service most agencies aren't selling.
After talking with dozens of agency owners, the pattern is always the same: they offer "maintenance" but don't actually monitor anything. A client's SSL expires, the site throws a security warning, and the agency finds out from an angry email the next morning.
This guide is a business playbook. Not "what is monitoring" — you know what monitoring is. This is about how to package website monitoring into a profitable agency service, what to charge, how to pitch it to clients, and the exact math behind the margins.
The MaaS Model: Monitoring as a Service
Your agency's new revenue line
MaaS (Monitoring as a Service) is a framework for packaging website monitoring into a recurring, client-facing service. You use a white-label monitoring platform behind the scenes. Clients see your brand, your dashboard, and your reports. They never see the tool.
The model works because it solves a real problem clients didn't know how to articulate: "I want someone watching my website 24/7 so I don't have to worry about it."
What you deliver
- •24/7 uptime monitoring of their website and key pages
- •SSL certificate monitoring with expiry alerts
- •Visual change detection (catches broken layouts before clients do)
- •A branded status page per client
- •Monthly health reports with your agency logo
- •Proactive incident response (you fix things before they call)
What it costs you
A white-label monitoring platform at a flat monthly fee. With PerkyDash Agency at €79/month for up to 25 clients, your per-client cost is €3.16. That's the entire infrastructure cost. No servers to manage, no scripts to maintain, no DevOps hire needed.
Here's the contrarian take: you don't need 20 monitoring features. You need 4: uptime, SSL, visual diff, and a status page. Everything else is noise for 90% of agency clients. Keep the service simple, keep the pricing clear, keep the margins high.

How Much to Charge: 3 Pricing Models
Real numbers, not theory
The agencies generating the highest margins charge €25–30/client/month for a service that costs them €3–5/client. That's 80%+ margin. Here are three proven pricing structures:
Flat fee per client — €19–29/month
Best for: agencies with mostly similar-sized client sites (brochure sites, small WordPress sites).
Includes uptime monitoring, SSL alerts, a status page, and a monthly report. Simple to explain, simple to sell. Clients understand exactly what they're paying for.
Margin at €25/client: 87% (cost €3.16/client on PerkyDash Agency)
Tiered packages — €19 / €39 / €79 per month
Best for: agencies with diverse client sizes (from freelancer sites to e-commerce).
| Tier | Price | Includes |
|---|---|---|
| Basic | €19/mo | Uptime + SSL monitoring, email alerts |
| Standard | €39/mo | + Visual diff, status page, monthly report |
| Premium | €79/mo | + Priority alerts, checkout monitoring, weekly reports |
Bundled with maintenance — €99–299/month
Best for: agencies that already sell maintenance retainers.
Add monitoring to your existing maintenance package. Clients who pay €149/month for "updates + backups + hosting support" now pay €199/month for that plus "24/7 monitoring + status page + monthly health report." The perceived value increase far exceeds the €50 price bump.
Pricing rule of thumb: Never charge less than €19/month per client. Below that, clients don't value the service. Above €79/month, you need to justify the price with premium features like checkout flow monitoring and dedicated incident response.
What You Need Technically
The four non-negotiables for an agency monitoring service
You don't need to build anything. You need a platform that does four things well. Here's the checklist:
White-label dashboard and branding
The client should never see the monitoring tool's brand. Custom domain (monitoring.youragency.com), your logo, your colors. If clients Google the tool's name and find it for €9/month, your €25/month service looks like a markup. White-label protects your margins.
For a deep dive into white-label requirements, see our white-label monitoring guide.
Multi-client management (workspaces)
One dashboard with isolated workspaces per client. You see everything. Clients see only their own monitors. No data leakage, no confusion, no manual separation.
Branded reports and status pages
Monthly reports with your agency logo showing uptime %, response times, incidents resolved, and SSL status. Plus a status page per client (status.clientsite.com) where they can check things themselves instead of emailing you.
Smart alerting with cooldown
With 15+ client sites, you'll get false positives. You need alerts with cooldown periods, confirmation checks, and tiered routing. Not every blip deserves a 2 AM notification.
Practical Setup: Launch in 30 Minutes
Step-by-step, from zero to monitoring 10 clients
In our experience, the average agency setup takes 25 minutes to brand the dashboard and add 10 client sites. Here's the walkthrough:
Sign up for an Agency plan
See how PerkyDash's Agency plan works. Start the 14-day free trial. No credit card required.
Configure your brand
Upload your logo, set your agency colors, choose your font. Point a subdomain (monitoring.youragency.com) to the platform. 5 minutes.
Create a workspace per client
Each client gets an isolated workspace. Their monitors, status page, and incidents are separate from other clients. Create 10 workspaces in about 3 minutes.
Add monitors per client
For each client, add: HTTP uptime check on their main URL, SSL certificate monitor, and (optionally) visual diff on the homepage. Takes about 1 minute per client.
Set up status pages
Create a status page per client. Add their monitors to it. Share the link in your onboarding email. See real status page examples for inspiration.
Configure alerts
Route alerts to Slack for your team, email for clients. Set cooldown periods to avoid alert fatigue. Premium clients get SMS escalation.
That's it. You now have a fully branded monitoring service for 10 clients. From here, it's about selling it.
The Revenue Math: 3 Scenarios
The numbers agencies actually see
The Revenue Math
15 clients × €25/month = €375 revenue
€79 PerkyDash Agency cost
€296/month profit
€3,552/year. From one tool.
| Scenario | Clients | Avg Price | Revenue/mo | Cost/mo | Profit/mo | Profit/yr |
|---|---|---|---|---|---|---|
| Starting out | 10 | €25 | €250 | €79 | €171 | €2,052 |
| Growing | 15 | €25 | €375 | €79 | €296 | €3,552 |
| Full capacity | 25 | €29 | €725 | €79 | €646 | €7,752 |
Notice the cost stays fixed at €79/month regardless of how many clients you add (up to 25). That's the beauty of a flat-fee platform. Every new client is almost pure profit.
And this is just the monitoring revenue. The real multiplier is retention: clients with active monitoring services churn at a fraction of the rate of project-only clients. You're not just earning €296/month — you're protecting the rest of your retainer revenue.
How to Pitch Monitoring to Existing Clients
The email that converts at 30%+
Don't sell "monitoring." Sell peace of mind. Sell "we'll know before your customers do." Here's the template that works:
Client Email Template
Subject: Your website was down last Tuesday (you might not have noticed)
Hi [Name],
Quick update — we've started doing proactive monitoring checks on our clients' sites, and yours had a brief outage last [day] at [time]. It lasted about [X] minutes. No damage, but you probably didn't know about it.
This is exactly the kind of thing that can escalate if nobody's watching. A few of our other clients have asked us to formalize this into an ongoing monitoring service, and I'd love to offer you the same:
• 24/7 uptime monitoring (checks every 60 seconds)
• SSL certificate expiry alerts
• A status page for your site: status.[yourdomain].com
• Monthly health report
It's €25/month, and I'll include the first month free so you can see the value before committing.
Want me to set it up?
Why this works
It leads with a real event. You're not selling hypothetical value. You caught an actual issue. (Run a free uptime check on their site first with our free uptime checker — you'll almost always find something.)
It mentions other clients. Social proof. They're not the guinea pig — other clients already use this.
Free first month removes friction. Once they've had a month of status page access and a health report, canceling feels like losing something.
The price is low enough to not need approval. €25/month doesn't require a meeting. It's a quick "yes."
For new clients, include 3 months of monitoring in your project proposal price. After the project launches, the monitoring converts to a monthly retainer. They're already used to it, so canceling feels like a downgrade.
Platform Costs: What Monitoring Actually Costs You
Comparing the platforms agencies actually use
Your per-client cost depends entirely on the platform. Here's what 15 clients costs you on each:
| Platform | Cost for 15 clients | Per client | White-label | Status pages |
|---|---|---|---|---|
| PerkyDash Agency | €79/mo | €5.27 | Full | Included |
| Pingdom | ~$100/mo | ~$6.67 | None | None |
| Better Stack | ~$85/mo | ~$5.67 | Limited | Included |
| UptimeRobot Pro | $7/mo | $0.47 | None | Basic |
| DIY (self-hosted) | $20+/mo + time | $1.33+ | Manual | Manual |
UptimeRobot is cheapest, but has no white-label and basic status pages. If a client Googles "UptimeRobot" and finds the free tier, your reselling margin evaporates. Pingdom has strong monitoring but zero agency features — no white-label, no multi-client management.
The honest comparison: if you purely want the cheapest monitoring and don't care about white-label, UptimeRobot wins. If you're building a branded agency service that clients perceive as yours, you need white-label, workspaces, and branded reports. That's where PerkyDash fits.
The 5 Mistakes Agencies Make with Monitoring
Learned from real agency conversations
1. Offering monitoring for free
The most common mistake: including monitoring as a "bonus" in a hosting package. It devalues the service and trains clients to expect it at no cost. Monitoring is a service, not a bonus. Charge for it. If you give it away, clients won't appreciate the value — and you won't invest in doing it well.
2. Using a non-white-label tool
If your status page says "Powered by UptimeRobot" and the client can sign up for free, you've destroyed your value proposition. White-label isn't a nice-to-have — it's essential for agency margins.
3. Not sending reports
If everything is green and you never communicate, clients forget they're paying for monitoring. Monthly reports justify the fee. They show uptime %, response times, and incidents handled. Even "100% uptime this month" is a valuable report — it proves the service works.
4. No status page per client
Without a status page, every "is it down?" question becomes a support ticket to you. A status page is self-service — clients check it themselves. Try our free emergency status page to see how fast you can get one running.
5. Monitoring uptime only
A site can be "up" but visually broken (CSS not loading, hero image missing, checkout button gone). Add visual diff monitoring for high-value clients. It catches layout issues that uptime checks miss. The client never needs to tell you "my site looks weird" — you already know.

Frequently Asked Questions
How much can an agency earn reselling website monitoring?
With 15 clients paying €25/month each, you generate €375 in monthly revenue against a €79 platform cost. That's €296/month profit, or over €3,500/year, from a single tool. Agencies with 25 clients routinely clear €5,000+ per year.
What is MaaS (Monitoring as a Service) for agencies?
MaaS stands for Monitoring as a Service. It means packaging uptime monitoring, SSL checks, visual diff, and status pages into a recurring monthly service you sell to clients. You use a white-label platform behind the scenes, but clients see your brand, your dashboard, and your reports.
Do I need technical skills to sell monitoring to clients?
No. Modern white-label monitoring platforms handle all the technical infrastructure. You add a URL, configure alerts, and the platform does the rest. If you can manage a WordPress site, you can run a monitoring service. The average setup takes 25 minutes to brand the dashboard and add 10 client sites.
How do I pitch monitoring to existing clients?
Lead with the problem, not the tool. Most clients have experienced downtime they only found out about from their own customers. Frame monitoring as insurance: for €25/month, they get 24/7 monitoring, instant alerts, a branded status page, and monthly health reports. Include a free first month to remove friction.
What monitoring features do agency clients actually need?
You need four core features: uptime monitoring (HTTP checks every 60 seconds), SSL certificate monitoring (alerts before expiry), visual diff detection (catches layout-breaking changes), and a branded status page per client. Everything else is a nice-to-have for 90% of agency clients.
