Website as a Service vs. One-Time Website Project: What Is the Difference?

A detailed comparison of the two main models for commissioning a professional website. What each model means, how ownership and costs work, and which approach suits which situation.

When a business decides to invest in a professional website, it typically faces two fundamentally different models: commissioning a one-time project from an agency or developer, or entering a subscription-based arrangement where the agency remains responsible for the site on an ongoing basis. Both models are widely used, and each has genuine advantages depending on the situation. This article explains how they work, where they differ, and what to consider when choosing between them.

What Is a One-Time Website Project?

A one-time website project is a fixed-scope engagement between a client and an agency or developer. The client pays a project fee, the agency designs and builds the website, and at the end of the project the finished site along with all code and design files is handed over to the client. The client then owns the website outright and is responsible for its hosting, updates, and ongoing maintenance.
This is the traditional model for professional web development. The scope is defined upfront: how many pages, what functionality, which integrations. Based on this scope, the agency provides a fixed price or a time-and-materials estimate. A typical small business website built this way takes four to eight weeks and costs anywhere from €2,000 to €10,000 depending on complexity.
After the project is completed and the files are handed over, the ongoing relationship with the agency typically ends unless a separate maintenance retainer is agreed. This means the client is responsible for keeping the hosting environment running, applying security updates, and managing any content changes or design adjustments. If the original agency is no longer available, a new developer needs to familiarise themselves with the existing codebase before making changes.

What Is Website as a Service?

Website as a Service (
WaaS
) is a subscription model in which the agency builds, hosts, and actively maintains the website for a recurring monthly fee. The client does not pay a large upfront project cost. Instead, the monthly fee covers design, development, hosting, updates, support, and typically a full redesign at the end of each subscription cycle.
The model was developed to address a problem that many businesses face after a traditional project: the website launches, looks good, and then slowly becomes outdated because the cost and friction of making changes is high enough that updates get deferred. In a
WaaS
model, the agency is contractually responsible for keeping the site current, so maintenance happens continuously rather than in expensive one-off interventions.
Subscription terms vary between providers. Some offer monthly cancellation. Others require a minimum term. The content of the subscription also varies considerably. At minimum, a
WaaS
subscription should include custom development, managed hosting,
SSL
certificates, and a defined response time for update requests. More comprehensive plans include content changes, SEO maintenance, performance monitoring, and periodic redesigns.

Who Owns the Website in Each Model?

With a one-time project, the client owns all code and assets immediately upon delivery. With
WaaS
, ownership depends on the contract terms. Some providers retain the code for the duration of the subscription and hand it over only at the end of a defined cycle. Others offer a code buyout option at any time. Reading the contract carefully on this point is important.
For the one-time model, full ownership from day one is one of the clearest advantages. The client can move the site to a different host, hire a new developer to modify it, or change direction entirely without asking anyone's permission. There are no ongoing obligations to the original agency.
In the
WaaS
model, the client's relationship with the website is more like a rental arrangement during the subscription period. This creates a dependency on the agency that does not exist in the one-time model. If the agency closes down or the relationship deteriorates, the client needs to either find a buyout option or start from scratch. Providers who offer clear code handover terms and buyout options at reasonable prices make this risk manageable.

How Do the Costs Compare?

A one-time project requires a larger upfront payment but usually lower ongoing costs, since the client controls hosting and only pays for changes when they need them.
WaaS
has no large upfront cost but creates a fixed monthly obligation. Over a period of two to three years, the total cost of both models tends to be comparable, though the distribution of payments differs significantly.
The one-time model's ongoing costs after delivery are often underestimated. Professional hosting runs roughly €20 to €80 per month depending on the setup. Security updates, plugin management, and performance maintenance add time that either the client handles or pays a developer to handle. Content changes and design updates, if they involve code, require developer time at agency rates. A business that plans to update its website frequently will accumulate these costs quickly.
WaaS
monthly fees typically range from €100 to €400 depending on scope and provider (Blackwell Studio's subscription starts at €148 per month). This fee includes hosting and basic maintenance. Whether it represents good value compared to the one-time model depends on how much ongoing support the business actually needs. For a website that changes rarely, a one-time project with minimal hosting costs will almost certainly be cheaper over three years. For a website that needs regular updates, a WaaS subscription can be more cost-efficient once developer time is factored in.

How Are Updates and Content Changes Handled?

In the one-time model, updates are handled separately from the original project, either through a retainer agreement or by commissioning individual changes as needed. In the
WaaS
model, a defined set of update types is included in the monthly fee. Both models require clarity upfront about what kinds of changes are covered and what cost additional work.
For businesses that manage content themselves, such as publishing blog posts, updating pricing, or editing product descriptions, both models can accommodate this. The one-time project can include a content management system that allows non-technical editing.
WaaS
providers typically offer the same. The real difference is in design and structural changes: moving sections around, adding new pages, or changing layouts. In the one-time model these require a separate development request. In WaaS they are typically included up to a monthly allocation.

What Are the Advantages of a One-Time Project?

  • Immediate full ownership of all code and design files
  • No ongoing financial obligation to the agency after delivery
  • Freedom to change hosting provider, developer, or technology stack at any time
  • Clear fixed cost upfront, no recurring fees tied to the agency relationship
  • Better suited to businesses with strong in-house technical capacity

What Are the Advantages of Website as a Service?

  • No large upfront investment required, lower barrier to entry for professional quality
  • Hosting, security, and maintenance are handled by the agency without additional coordination
  • Regular redesigns and updates keep the site current without a separate project each time
  • A single monthly payment covers a defined set of services with predictable cost
  • Better suited to businesses without in-house technical capacity or time to manage a website

What Are the Risks of Each Model?

The main risk of the one-time model is the maintenance gap: without a plan for ongoing updates, a custom-built site slowly becomes outdated in design, performance, and security. The main risk of
WaaS
is agency dependency: if the provider relationship ends unexpectedly, the client may face disruption. Both risks can be managed with clear contracts and planning.
For the one-time model, the maintenance gap is especially common for small businesses. The website launches well, then a year later the design looks dated, some links are broken, and performance has degraded because nobody applied updates. Agreeing to at least a lightweight maintenance retainer alongside the project cost avoids this.
For
WaaS
, the agency dependency risk is mitigated by providers who offer transparent code handover terms. If the codebase is available for buyout at a reasonable price at any time, the client always has an exit path. Contracts that lock the client in with no code access should be treated with caution.

Do WaaS Providers Charge a Setup Fee?

Practice varies considerably. Some
WaaS
providers charge an initial setup fee to cover the cost of building the site before the subscription begins. These fees typically range from €50 to €500 depending on the scope and the provider. Others, including Blackwell Studio, charge no setup fee at all and absorb the onboarding cost into the subscription model instead. There is no industry standard, so this is a point to clarify before signing anything.
The rationale behind a setup fee is straightforward: designing and developing a website takes significant time, and charging only a recurring monthly fee makes the early months economically unfeasible for the agency. Providers who waive the setup fee either absorb that cost across a longer expected contract term or operate at lower margins during onboarding.
Minimum contract terms follow a similar pattern. Some
WaaS
providers require a six or twelve month commitment before the client can cancel. Others allow monthly cancellation from the start, which is the approach Blackwell Studio takes. A longer minimum term protects the provider's investment in building the site. A shorter or no minimum term puts the flexibility with the client but may be reflected in the monthly rate.

What Happens to the Website When the Subscription Ends?

This is the most important contractual question in any
WaaS
agreement. The answer varies significantly between providers. Some retain full ownership of the codebase for the duration of the subscription. Some offer a code buyout at any point for a fixed fee. Others automatically hand over the code at the end of a defined cycle. Each approach has different implications for the client's long-term position.
A subscription that includes no code handover path means the client is permanently dependent on the provider. If the provider raises prices, changes service quality, or closes entirely, the client has no technical asset to take elsewhere. A subscription that includes a defined handover mechanism gives the client a clear exit path and makes the arrangement more comparable to a long-term lease than a pure service dependency.
Some providers handle this with a tiered approach: the client can buy out the code at any point during the subscription at a price that decreases over time, reflecting how much of the build cost has been recovered through monthly fees. After a full cycle, typically two years, the code is handed over as part of a redesign process. Blackwell Studio follows this model: after two years the full codebase is transferred to the client, and any early exit is handled through a reduced buyout rather than the full project rate.

Which Model Is Right for Which Situation?

The one-time model tends to work well for businesses that have technical capacity in-house, that want full control over their infrastructure from the start, or that are building a platform with a specific architecture that will be maintained by their own team. It is also the right choice when the scope is well-defined and unlikely to change frequently.
WaaS
tends to work well for businesses that want professional web presence without managing technical details, that update their site regularly, that have found previous one-time projects difficult to maintain after delivery, or that prefer to spread the cost over time rather than pay a large upfront sum.
What matters most when evaluating any
WaaS
offer is not the monthly price in isolation but the total picture: what is included, what happens at the end, and what options exist if the relationship ends earlier than planned.
