Most agencies already build and maintain their clients' websites. Far fewer host them — and that's a missed opportunity. Hosting is recurring, it's sticky, and if you own the stack the margins are excellent. The catch has always been the tooling: reselling hosting used to mean either a clunky cPanel/WHM licence or a per-account SaaS that eats your margin as you grow. White-label hosting on a panel you own fixes both. Here's how it works.

Why agencies should host their own clients

Recurring revenue. A one-off site build pays once. Hosting pays every month, for years. It smooths out the feast-or-famine cycle every agency knows.
Retention. When you host the site, you're in the loop for every change, renewal and fix. Clients don't drift to a cheaper freelancer because you are the infrastructure.
Control. You choose the stack, the PHP version, the backup policy and the security posture — instead of debugging a client's random shared host at 2 a.m.
Margin. A €5 VPS can comfortably host a dozen small business sites. Bill each client €15–30/month for "managed hosting" and the maths speaks for itself.

The only thing standing between most agencies and this revenue is a tool that lets them present hosting as their product, not someone else's.

The problem with per-account SaaS

The obvious route is a managed hosting SaaS or a reseller plan. It works, but it has two structural problems:

You pay per account, forever. Every client you add increases your bill. Your costs scale linearly with your success, which quietly caps your margin.
You don't own the relationship or the stack. Your clients live on someone else's platform under someone else's terms. If the provider raises prices, changes features or has an outage, you inherit the fallout with none of the control. And your "brand" is really just a logo bolted onto their dashboard.

For an agency, that's backwards. The whole point of hosting your clients is to own the relationship.

How white-label hosting works with ShadowPanel

ShadowPanel Agency turns a single VPS you control into a hosting platform that looks and feels like yours:

Your branding. Replace the ShadowPanel logo with yours, set your brand colours, and serve the panel from your own subdomain (for example hosting.youragency.com). Clients who log in see your brand, not ours.
Reseller accounts. Create isolated accounts for each client. They can manage their own site — files, email, backups — without ever seeing other clients or touching the server.
Unlimited sites, flat fee. Agency is a single flat licence (€29/month or €290/year), not a per-account charge. Add your fourth client or your fortieth — the licence cost doesn't move.
The full stack, per site. Every client site gets isolated PHP-FPM, its own databases, free auto-renewing SSL, email, and encrypted S3 backups — on hardware you own.

Because it's self-hosted, there's no platform between you and your clients. You set the terms.

A concrete setup: billing hosting to your clients

Here's a realistic way to run it:

Provision one VPS — a Hetzner CAX21 (4 vCPU, 8 GB RAM) comfortably runs a dozen or more small-business sites and costs a few euros a month.

Install ShadowPanel and activate your Agency licence:

curl -fsSL https://shadowpanel.de/install.sh | bash

Apply your branding — logo, colours, and your subdomain — so the panel is unmistakably yours.
Create a reseller account per client, add their site, point their domain, and let ShadowPanel issue SSL automatically.
Bill your way. ShadowPanel handles the hosting; you handle the billing with whatever you already use (Stripe, an invoicing tool, a retainer). Charge each client a flat monthly managed-hosting fee. The gap between that and your VPS cost is your margin.

Do the arithmetic: ten clients at €20/month is €200/month in, against a VPS and one flat Agency licence — comfortably under €40/month out. That spread is recurring, and it grows with every client you add, not your costs.

Honest caveats

You're now the host. Owning the stack means owning uptime, updates and backups. ShadowPanel hardens the server by default (UFW, Fail2ban, CrowdSec) and automates SSL and backups, but the responsibility is yours. For agencies that already manage client sites, that's usually a step you're taking anyway.
One big VPS is a single basket. For a serious hosting business, split clients across a couple of servers, or move larger clients onto their own — the flat Agency licence doesn't punish you for running more than one panel.
It's not a billing platform. ShadowPanel does hosting and white-label, not invoicing or a client-facing order form. Pair it with your existing billing tool.

The bottom line

White-label hosting turns work you may already be doing — managing client sites — into recurring, high-margin revenue under your own brand. The key is owning the stack instead of renting it per account, so your margin grows with your client list instead of shrinking. ShadowPanel Agency gives you the branding, reseller accounts and unlimited sites to do exactly that, on a single flat licence.
