The real calculation is not about the starting price
For an SMB, comparing a custom-built site and a template only on the initial quote is a flawed method. What matters is the total cost of ownership (TCO) over three to five years: the starting price, but also maintenance, plugins, redesigns, and above all the lost revenue caused by a slow or undifferentiated site. A 500 € template can end up costing more than a custom site once these items are added up.
The advertised price is misleading because it only measures a single moment. A website is not a purchase, it is an asset that works (or fails to) every day for years. The right question is therefore not "what does it cost today" but "what does it earn or cost me every month until the next redesign".
What a template truly costs over time
A template looks cheap to buy, but accumulates hidden fees spread across its entire lifespan. These are the items SMBs forget most often:
- Paid plugins: a WordPress template quickly needs 5 to 15 extensions (forms, SEO, cache, security, booking), often on annual subscriptions of 30 to 80 € each.
- Maintenance and updates: every theme or plugin update can break the layout. You have to test, fix, and sometimes pay a provider in an emergency.
- Slowness that costs conversions: templates load generic, unused code. A site that goes from 2 to 5 seconds of load time loses a measurable share of its visitors before they even see the offer.
- Premature redesign: a template ages poorly and is often replaced after 2 or 3 years, where a healthy foundation lasts 5 years and beyond.
Add it up: 500 € upfront, 600 € of plugins per year, a few days of maintenance, and an early redesign. The real bill far exceeds the price on the product page.
Performance and Core Web Vitals: the invisible line item
Technical performance is the most underestimated hidden cost of a template. Google evaluates pages through Core Web Vitals (loading speed, responsiveness, visual stability), and these metrics influence both search ranking and conversion rate.
A template loads libraries, fonts and scripts of which you use only 10 percent. A custom site built in Next.js loads only what is needed: optimized rendering, images served in the right format, split code. The result is pages that display in under two seconds and meet Core Web Vitals thresholds without patches.
“On mobile, every extra second of load time drives the conversion rate down. Speed is not a technical detail: it is a revenue line.
For a local SMB in the Hauts-de-France region fighting to rank ahead of a competitor on "plumber Lille" or "florist Roubaix", this performance gap weighs directly on the number of calls and quote requests received each month.
Differentiation: a template is the same suit as thousands of others
A template is by definition shared by thousands of other businesses, which dilutes your brand image. Your prospects have already seen your layout elsewhere, sometimes at a direct competitor. For an SMB that wants to justify its pricing and inspire trust, looking like everyone else is a silent handicap.
Custom work reverses the logic: structure, journeys and design serve your offer, not the other way around. You can highlight what sets you apart (a craft expertise, a service area, a guarantee) where a template imposes its rigid blocks. This differentiation translates into trust, and trust into conversion.
Scalability and longevity: building on solid ground
Custom work is more profitable in the long run because it evolves with your business without rebuilding everything. A well-designed Next.js site is a foundation you extend: adding online booking, a client area, a shop, new local pages for SEO. You build on what exists instead of starting from scratch.
Longevity also means not depending on a theme that may be abandoned by its publisher, nor on a stack of plugins that will eventually conflict. Clean, well-controlled code ages slowly and stays maintainable by any competent developer.
When a template is enough (and when it no longer is)
A template can perfectly fit in some specific cases, and it would be dishonest to pretend otherwise. It is relevant when:
- The need is temporary: a holding page, a one-off event, a market test to validate before investing.
- The budget is zero: a template online beats no site at all.
- The site is not strategic: if your business does not rely on the web to find customers.
Conversely, as soon as the site becomes a serious acquisition channel, one that must perform, convert and last, custom work regains the advantage. For an ambitious SMB, the initial price gap is repaid through conversions gained and redesigns avoided.
The honest calculation to decide
The right decision rests on a five-year projection, not on today's quote. Put on paper the starting price, the annual subscriptions, the cost of a likely redesign, and estimate the conversions lost to slowness or lack of differentiation. Compare that total across both scenarios. In most cases where the web truly matters, custom comes out ahead not on principle, but on arithmetic.
At Fautho Consulting, a custom showcase site starts at 2,500 € and an e-commerce site from 7,000 €: an investment designed to last five years and work for you, not to be redone in two.
