Off-the-shelf SaaS vs custom site in Singapore in 2026: when to switch

The verdict in three sentences

A SaaS builder at 350 EUR/month is perfect to start fast, but it becomes a perpetual rent of 4 200 EUR/year you never own. A custom site at 14 000 EUR amortised over 4 years works out to 3 500 EUR/year and becomes cheaper than the subscription by year 4, before counting SaaS overage fees. The 2026 rule: stay on SaaS under a 3-year horizon or for standard needs; switch as soon as you pass 3 years of use or your needs turn specific.

The costed tipping point

An honest comparison doesn't pit 350 EUR/month against a one-off 14 000 EUR: it stacks SaaS rents against an amortised asset. Here is the 5-year projection.

Custom here includes 1 200 EUR/year of maintenance. The crossover happens between years 3 and 4: beyond that, each SaaS year costs 4 200 EUR while custom only costs its maintenance.

Beyond price: ownership and specificity

Cost is only half the equation. SaaS rents you standard features; custom makes you the owner and frees your roadmap.

Lock-in is the invisible SaaS cost: when you want to leave, exporting your data and design often costs 2 000-4 000 EUR of rework. Custom, by contrast, is your property from day one. There's also a strategic dimension: on SaaS, your roadmap depends on the vendor's priorities, and they can remove a feature, raise prices or shut the plan down overnight. In 2026, several builders lifted prices by 15 to 30% in a single year, a risk custom neutralises. Owning your foundation also means you can integrate an ERP, a local payment method or a domain-specific AI tomorrow without asking a third-party platform for permission.

Mini case study

Nadia, director of a services SME in Singapore (18 staff), has paid 350 EUR/month for a builder for 14 months and is hitting limits: she wants a product configurator the SaaS charges 180 EUR/month extra.

Her SaaS would rise to 530 EUR/month, i.e. 6 360 EUR/year. Custom, with the configurator included, costs 14 000 EUR + 1 200 EUR/year maintenance. Over 4 years: SaaS = 25 440 EUR, custom = 18 800 EUR, i.e. 6 640 EUR saved and an owned asset at the end. The tipping point falls at the end of year 2 given the module surcharge. Nadia switches: she turns a rising rent into an amortised investment and gains a feature the SaaS could never tailor to her process.

FAQ

From when does custom become cheaper?

2026 order of magnitude: the crossover sits between years 3 and 4 for a SaaS at 350 EUR/month versus custom at 14 000 EUR. With extra paid modules, the switch can fall as early as year 2.

What does a SaaS builder really cost per year?

Between 1 800 and 5 400 EUR/year by plan (150-450 EUR/month), excluding overage fees of 50-300 EUR/month as traffic or sales grow. That rent builds no asset.

Is SaaS really a trap?

Not to start: it's ideal for the first 12-24 months. The trap is lock-in: leaving costs 2 000-4 000 EUR of rework and you own neither the code nor sometimes your templates.

When is staying on SaaS the right call?

If your horizon is under 3 years, if your needs stay standard, and if you want zero technical team. Below that threshold, custom doesn't amortise.

What happens to SEO and performance?

A builder caps your optimisations (LCP, tags, structure). Custom lets you target an LCP < 1.8 s and full technical SEO, which can be worth several conversion points over time.
