If you build WordPress sites for a living, you’ve probably felt this pattern before: you finish a project, send the final invoice, and the revenue meter resets to zero. Website as a Service is the model most agencies reach for to break that cycle.
Website as a Service (WaaS) is a subscription model where an agency sells ongoing access to a website or software product instead of a one-time build. The agency owns the infrastructure, the client pays monthly or annually, and revenue compounds with every new subscriber instead of restarting after each handover. It’s the SaaS playbook, run by people who already know how to build on WordPress.
Website as a Service, Defined Properly
The term gets used loosely, so it’s worth being specific. In its narrowest form, WaaS means an agency builds a website once, then licenses ongoing access to it – hosting, updates, and support bundled into a recurring fee, rather than billed as a separate project.
That’s the version most WaaS guides describe: pick a template, spin up a site for a client, charge them $50–$150 a month for hosting and “maintenance,” repeat. It’s a genuinely good deal for a lot of small local-business clients.
But there’s a second, less-talked-about version of WaaS that’s arguably a better fit for agencies with any kind of specialism: instead of reselling a website, you resell software – a purpose-built dashboard for a specific industry, running on WordPress multisite infrastructure you control, white-labeled under your own brand. A church gets a portal for giving, attendance, and events. A gym gets one for memberships and class bookings. The agency sets the price, keeps the client relationship, and the client gets something closer to a SaaS product than a brochure site.
How Is WaaS Different From a Normal WordPress Project?
A normal project is priced once, delivered once, and the agency’s income from it ends the day the invoice clears (unless the client comes back for more work). WaaS flips the economics:
| Project-based WordPress | Website as a Service | |
| Pricing | One-time fee | Monthly or annual subscription |
| Revenue over time | Resets after delivery | Compounds as clients are added |
| What the client owns | The finished site | Access, for as long as they subscribe |
| Agency’s core asset | Billable hours | A product, built once, sold repeatedly |
That last row is the real shift. In a project model, your capacity caps your income – you can only sell as many hours as your team has. In a WaaS model, the thing you’re selling is the same dashboard, reused across every client who signs up, so growth doesn’t require growing headcount at the same rate.
Why Are WordPress Agencies Moving to a WaaS Model?
Three reasons come up in almost every agency’s version of this story:
Predictability. A retainer client is worth more than a project client, even at a lower monthly number, because you can plan around it. Twenty clients on a $79/month portal is $1,580 in revenue you can forecast every single month, not twenty separate sales conversations you have to win again next quarter.
Lower client-acquisition pressure. Agencies running pure project work are always one slow month away from a cash-flow problem, because the pipeline has to keep refilling. A subscription base cushions that – new sales become growth on top of a floor, not the entire income.
A sellable asset. A book of thirty $99/month subscribers is worth something concrete if you ever sell the agency. A pipeline of one-off projects generally isn’t.
None of this is new – agencies have been building recurring revenue through hosting and maintenance retainers for years. WaaS is really just the natural extension of that instinct, applied to something with more margin than hosting resale usually has.
Two Kinds of WaaS: Template Resale and Vertical Software
Most of what gets written about WaaS describes the first kind: pick a design template, deploy it per client, bundle in hosting and updates. It’s a reasonable model, and plenty of agencies run profitable businesses on it.
The second kind is narrower and, for agencies willing to specialize, more defensible: sell vertical software rather than a generic site. This is closer to what older WordPress multisite tools were originally trying to enable – plugins like WP Ultimo turned a multisite install into subscription infrastructure, though that particular tool has been unmaintained since late 2023, which is part of why the category has been quietly waiting for someone to finish the job properly.
The distinction matters because of what the client is actually buying. A generic template site competes on price with every other agency offering the same thing. A church management portal, a gym membership system, or a real estate client dashboard competes on fit – and fit is much harder for a client to walk away from, because switching means re-training staff and migrating data, not just picking a cheaper hosting bill.
Is WaaS Right for Every Agency?
Not automatically. A few things need to be true first:
- You need repeatable demand. WaaS pays off when you can sell the same product to many clients. If every client’s needs are genuinely bespoke, there’s nothing to productize yet.
- You need the patience for the early months. Recurring revenue starts small and compounds – the first ten subscribers won’t replace a project’s worth of income, but the fortieth subscriber costs you almost nothing extra to onboard.
- You need infrastructure you’re not maintaining yourself. This is where a lot of agencies stall out: building a multisite SaaS layer from scratch is a real engineering project, not a weekend plugin install, and it’s the reason many WaaS attempts never get past a handful of clients.
What This Looks Like in Practice
WPWaaS is built around the second kind of WaaS – a finished, white-label portal an agency subscribes to and deploys under its own brand, priced by the number of client sites rather than by revenue share.
The Church Portal is the first live example: membership, online giving, attendance, events, sermons, and groups, deployable on your own domain with no code required to set up.
Pricing runs on tenant count rather than features – an agency starting out can run up to five client church sites for $49/month, scale to thirty for $99/month, or go unlimited at $149/month, with a one-time lifetime option for agencies planning to build this out at scale. Full plan details are on the pricing page. What the agency charges its own clients, and what it keeps, stays entirely separate from that.
The Model, Not Just the Buzzword
“Website as a Service” gets used to describe everything from a $30/month template site to a fully white-labeled vertical SaaS product, and that range is exactly why it’s worth being precise about which version you’re building.
The template version is a reasonable way to add recurring revenue to a project-based agency. The vertical-software version asks more of you upfront but builds something closer to a real product – one clients are less likely to leave, and one that’s harder for a competitor to simply copy.
