WordPress Maintenance for Web Agencies

You're good at building WordPress sites. Your clients love the designs, the functionality, the launch experience. But three months later, a plugin update breaks a contact form, or a client emails asking why their site is slow, or WooCommerce pushes a major release that needs testing across a dozen stores. That maintenance work isn't what your agency was built for — but it's what keeps client relationships intact.

I'm Michal, a UK-based WordPress developer at Rootscope. I provide ongoing WordPress maintenance for web agencies across the UK. You build the sites, I keep them running. I currently manage 70+ WordPress sites across multiple servers, many of them through agency partnerships. This is what I do full-time — not a side service tacked onto a design agency. Maintenance and server management are my core business.

How the Partnership Works

The model is straightforward: your agency handles design, development, and client relationships. I handle the ongoing technical maintenance — updates, backups, security, performance, and server management. Your clients stay with you. I work behind the scenes.

Onboarding is simple. You provide me with access credentials for the sites you want maintained. I run an initial audit on each site covering WordPress core version, plugin and theme status, security posture, performance baseline, and server health. I document any issues that need immediate attention and provide a prioritised remediation plan.

Monthly maintenance cycle. Each site goes through a structured monthly cycle: plugin and theme updates tested and applied, security scans reviewed, backups verified, uptime logs checked, and database health monitored. I apply updates on a staggered schedule — not all sites on the same day — so I can catch any update-related issues before they cascade across your portfolio.

Communication. I adapt to your workflow. Some agencies want me to communicate directly with their clients when there's a technical issue. Others want all communication funnelled through their project manager. Some use Slack, others use email. I work however you work. The key principle is that I never surprise your client — if something needs their attention, you know first.

No overlap, no stepping on toes. I don't redesign pages, add new features, or make content changes unless explicitly asked. My scope is maintaining what exists — keeping it updated, secure, fast, and online. When a client needs new development work, that goes back to your team. If you want me to implement a specific change as part of maintenance, I'll do it — but I won't scope-creep into your territory.

Scale and Reliability

Maintenance at scale requires systems, not heroics. I've built my practice around managing a large number of sites reliably.

70+ sites under active management across multiple servers, hosting providers, and technology stacks. Some are simple brochure sites. Others are high-traffic WooCommerce stores processing hundreds of orders daily. I maintain sites on cPanel/WHM, CloudPanel, WP Engine, Kinsta, DigitalOcean, AWS, and bare-metal dedicated servers. The stack doesn't matter — the process does.

350+ plugin updates per month applied and tested. I don't just click "Update All." Each update is reviewed for known issues, tested in context, and monitored after deployment. When a plugin update breaks something — and they do — I catch it and roll back before your client notices.

Structured maintenance windows. Updates are applied during low-traffic periods and staggered across the portfolio. If a WooCommerce update causes issues on the first site I apply it to, I hold it for the rest until the problem is resolved. Your sites benefit from each other — the first site to get an update serves as a canary for the others.

Documented processes. Every site has a maintenance record covering access credentials, hosting details, plugin inventory, known issues, and client-specific requirements. If a site has a custom deployment process, a staging environment requirement, or a plugin that should never be updated automatically, it's documented and followed every time.

White-Label Option

Many agencies I work with don't want their clients to know there's a third party involved in maintenance. That's perfectly fine.

White-label reporting. Monthly maintenance reports can be branded with your agency's logo and delivered under your name. The reports cover updates applied, security events, uptime statistics, and recommendations — presented as if your agency produced them.

White-label communication. If you want me to communicate with your clients on technical matters, I can do so using your agency's email domain and branding. To the client, I'm a member of your team. This works particularly well for agencies that want to offer maintenance as a service but don't want to hire a full-time systems administrator.

Your brand, my expertise. The client relationship stays with you. I provide the technical capability. This arrangement works because we're not competing — I'm not a design agency, and I'm not trying to be one. I'm a maintenance and infrastructure specialist. Your clients need both, and this partnership gives them both without you having to build and staff an operations team.

SLA and Response Times

I operate a tiered priority system that ensures urgent issues get immediate attention while routine maintenance follows a predictable schedule.

Critical priority — site down, checkout broken, security breach, data loss risk. Response within 2 hours during UK business hours. These issues take precedence over everything else. If your client's WooCommerce store stops taking orders at 11am, I'm on it immediately — not after I finish updating plugins on another site.

High priority — significant functionality broken but site is operational. Contact form not sending, specific pages returning errors, search not working. Response within 4 hours during business hours. These are disruptive but not revenue-critical, and they get handled the same day.

Normal priority — plugin update requests, performance questions, minor configuration changes. Handled within the regular maintenance cycle, typically within 1-2 business days. These are the routine tasks that keep things running smoothly.

Scheduled maintenance — monthly updates, security audits, database optimisation, and reporting. These follow the documented maintenance schedule and are handled proactively — your agency and your clients don't need to request them.

For agencies managing ecommerce sites where downtime directly impacts revenue, I offer enhanced SLA options with shorter response commitments and out-of-hours availability. These are priced based on the specific requirements and number of sites covered.

Reporting for Agency Clients

Reporting serves two purposes: it keeps your agency informed about what's happening with your clients' sites, and it gives you something tangible to share with clients that reinforces the value of their maintenance plan.

Monthly maintenance reports cover:

• Updates applied — every WordPress core, plugin, and theme update applied during the month, with version numbers and any issues encountered
• Security events — login attempts blocked, malware scans completed, vulnerabilities patched, any suspicious activity investigated
• Uptime statistics — percentage uptime, any downtime incidents with duration and cause, response time trends
• Database health — table sizes, autoload data volume, query performance metrics, any optimisation work performed
• Recommendations — suggestions for improvements, upcoming end-of-life dates for PHP versions or plugins, potential security concerns

Reports are delivered in a format you can forward directly to clients or incorporate into your own client reporting. PDF, email, or dashboard access — whatever fits your workflow.

Quarterly reviews for agencies managing 10+ sites with me. These cover portfolio-wide trends, upcoming maintenance considerations (major WordPress releases, PHP version end-of-life), and capacity planning for new sites.

What It Costs

Agency pricing is based on the number of sites and their complexity. I offer volume discounts for agencies managing multiple sites through me — the more sites you bring, the lower the per-site cost.

Standard WordPress maintenance plans start from £27.99/month per site. Agency partnerships with 10+ sites receive discounted per-site rates. Custom SLA arrangements and white-label reporting are available as add-ons.

There are no setup fees, no long-term contracts, and no penalties for adding or removing sites. The arrangement is as flexible as your client roster.

For WooCommerce stores that need specialist attention — payment gateway monitoring, subscription management, database performance — I offer dedicated WooCommerce maintenance plans that cover the additional complexity.

Your agency's reputation depends on the sites you've built continuing to work well long after launch. My job is to make sure they do — quietly, reliably, and without consuming your team's time or attention.

If you're spending developer hours on maintenance work that could be handled by a specialist, or if your clients are starting to notice performance and security issues that fall between the cracks, let's talk. I'll set up a trial with a few sites so you can see how the partnership works before committing your full portfolio.
