Enterprise-grade hosting for demanding agencies
Per-client account resource isolation
Every client environment has guaranteed CPU and memory allocation. A traffic spike for client A has zero effect on client B - essential when you're issuing SLAs to enterprise clients.
Fully white-label platform
Your logo, your colors, your domain name on the management portal. Even system emails (password resets, quota alerts) are sent from your own address. Your brand, our technology.
Bulk operations for multi-site management
Roll out WordPress updates, PHP version changes, and SSL renewals across all your client accounts at once. No more site-by-site manual work - save hours per week.
SLA and uptime monitoring
Get real-time alerts for performance issues on client accounts. Our monitoring detects problems before your client notices them. 99.9% uptime contractually guaranteed.
Dedicated support with a fixed point of contact
From the Medium plan onward, you get a dedicated technical contact who knows your infrastructure. No queues, no re-explaining - direct communication with someone who understands your setup.
Automated security per account
Imunify360 protects each client account individually with malware scanning, firewall, and brute-force detection. If one account is compromised, the rest stay safe thanks to full isolation.
Start with your own domain name
Instantly check whether your desired domain name is still available
From agency to hosting partner: the growth strategy
The transition from pure web development to web development plus hosting works best in phases. Here's the playbook successful agencies follow:
Phase 1: Proof of concept (month 1-2)
Start with a Basic reseller plan and migrate 5-10 existing client websites. Test your workflow: how fast can you create accounts? How does restoring a backup go? How quickly does support respond? Use this phase to set up your internal processes.
Phase 2: Standardization (month 2-4)
Define your hosting offering: which plans do you offer, at what prices, with what SLA? Write a short hosting contract or add it to your existing service agreement. Train your team in using DirectAdmin. Offer hosting by default on new projects.
Phase 3: Migration (month 4-8)
Approach your existing clients who are with other hosts. Offer a free migration in exchange for an annual contract. Most clients appreciate having everything with one party. Expect a conversion rate of 60-70% - clients already trust you.
Phase 4: Optimization (month 8-12)
Automate wherever possible. Link your billing to DirectAdmin via the API. Implement monitoring tools. Build a knowledge base for your team. At this point, your hosting arm runs largely on routine and delivers predictable monthly revenue.
Phase 5: Expansion (year 2+)
Consider additional services: managed WordPress updates, security audits, performance optimization. Each of these services increases your average revenue per client and strengthens the client relationship.

Multi-site management for agencies: best practices
Efficiently managing large numbers of websites is what sets an agency apart from a freelancer. Here are the tools and techniques that make the difference:
1. Centralized dashboard
DirectAdmin's reseller interface shows all client accounts in one overview. You see disk usage, bandwidth, and the number of active domains per client at a glance. Sort by resource usage to quickly identify problem accounts.
2. Template-based account creation
Create account templates for your standard hosting plans (e.g. "Standard", "Premium", "Enterprise"). Creating new client accounts then literally takes 30 seconds: pick the template, enter the domain name, done.
3. Proactive monitoring
Set up email alerts for: disk usage above 80%, unexpected traffic spikes, failed backups, and SSL certificates expiring within 14 days. Acting proactively prevents support tickets and maintains customer satisfaction.
4. Standardized security baseline
Define a security baseline for all accounts: minimum PHP version, mandatory SSL, Imunify360 active, directory listing disabled. Apply this automatically to every new account. This guarantees a consistent security level across your entire portfolio.
5. Per-client documentation
Keep a concise record per client account: contact details, specifics (custom PHP modules, special DNS configuration), date of last major update, and any known issues. This saves enormous amounts of time during troubleshooting and team handovers.
Frequently asked questions about reseller hosting for agencies
That depends on your plan. The Basic plan supports 30 client accounts with 100 domains. The Ultimate plan goes up to 150 accounts with unlimited domains. For agencies with more than 150 client accounts, we offer custom solutions.
Each client account runs in an isolated container with its own CPU and RAM limits. If one client experiences a spike due to heavy traffic or a resource-intensive cron job, it doesn't affect the resources of other accounts. This is similar to VPS-style isolation, but within a reseller environment.
Yes. All reseller plans come with a 99.9% uptime SLA. That works out to a maximum of 8.7 hours of downtime per year. With the Deluxe and Ultimate plans, you can also arrange custom agreements on our support team's response times.
You can combine your reseller hosting with WHMCS, HostBill, or a similar billing system. This automates account creation, invoicing, and domain management. DirectAdmin offers API integrations that let you automate the entire process.
From the Basic plan onward, our SiteSwitch migration service is included for free. Our team migrates your client websites including databases, email, and DNS settings. For large migrations (50+ sites), we create a custom migration plan so everything goes smoothly.
With reseller hosting, you manage client accounts via DirectAdmin without worrying about server maintenance - we handle updates, security, and monitoring. A managed VPS gives you more control over server settings but also requires more technical knowledge. For most agencies, reseller hosting is the best balance between control and convenience. Consider a <a href="/en/managed-vps/">managed VPS</a> if you need specific server software.
Absolutely, and that's exactly what many of our agency clients do. You start with a reseller plan, build up a client base, and can eventually upgrade to a dedicated server or VPS if you want full control. Theory7 grows with you - from your first reseller plan to a full-fledged hosting business.
From agency to hosting partner: the growth strategy
Web agencies face a strategic choice: refer clients to external hosting providers, or make hosting a core part of your service offering? More and more agencies are choosing the latter. With reseller hosting According to HostAdvice, the reseller hosting market grows 15% annually. you add a scalable, recurring revenue stream to your agency without having to set up your own data center.
Why agencies make the switch
The main reason is control. If your clients are with an external host, you depend on their uptime, their support, and their decisions. Does the host have an outage? Your client calls you - but you can't do anything. With reseller hosting, you manage the entire stack: from account creation to PHP configuration to backup restores. WHMCS is the most widely used platform for hosting automation.
The second reason is financial. An agency with 80 client websites charging €15/month per site for hosting and basic maintenance generates €14,400 per year in recurring revenue. That's predictable income that continues even during quiet periods when fewer projects come in.
Multi-site management for agencies: best practices
Efficiently managing dozens or hundreds of websites requires a structured approach. Here are the best practices successful agencies apply:
- Standardize your stack: use the same PHP version, the same WordPress configuration, and the same security plugins across all client accounts. This enables bulk updates and drastically reduces troubleshooting time.
- Automate monitoring: set up alerts for downtime, high server load, and SSL expirations. Proactively solving problems before the client notices them is the difference between a good and an excellent hosting service.
- Document per client: track which plugins are active, which customizations have been made, and who the contact person is per account. At 100+ sites, this isn't optional, it's necessary.
- Plan maintenance in blocks: reserve a fixed time each week for updates and checks across all accounts. Working in batches is far more efficient than handling things ad hoc per site.
Scaling without growing pains
The great thing about the Theory7 reseller model is that you can scale seamlessly. Starting with 20 client websites on the Basic plan? Upgrade to Medium once you approach 50. Managing 100+ sites? The Deluxe plan offers the resources you need. And for the largest agencies, there's the Ultimate plan or even a dedicated server solution.
Every upgrade happens with no downtime and no data migration. Your client accounts, settings, and data stay exactly the same - only the underlying resources grow with you. That makes growth predictable and risk-free.
The financial impact for your agency
Hosting as a service transforms an agency's business model. Instead of purely project-based income (peaks and valleys), you build a stable base of monthly recurring revenue. After three to five years, that hosting arm can represent 20-30% of your total revenue - with minimal extra effort.
