Saas Website Translation

SaaS website translation is harder than ecommerce localisation because every feature page, every pricing tier, every demo CTA and every doc article must stay synchronised across languages as your product ships. Get the marketing-site translation perfect and the docs three releases out of date and you will have French enterprise buyers churning before they finish trial. The fix is feature-perfect localisation across the four content layers — marketing, pricing, product UI strings, and docs — bound to a continuous-sync workflow that triggers on every product release, not on a quarterly cadence.

What SaaS sites need that ecommerce doesn't

A typical SaaS marketing site has 40-80 unique pages: feature pages, integrations, use-case pages, pricing, comparison pages, security/compliance, customer stories, blog, docs index, plus 200-2,000 doc articles. That is 5-10x the surface area of a typical ecommerce store, and every page references product features by name.

Every feature rename, every pricing change, every new integration partner forces a coordinated update across all language versions. The marketing site cannot say "Workspaces" in English and "Espaces de travail" in French if the product UI in French still shows "Workspaces". Localisation parity is a buyer signal — French enterprise buyers read the docs before they book a demo, and they spot drift immediately. CSA Research's enterprise localisation studies have repeatedly shown that B2B buyers in France, Germany, and Japan rate localisation quality as the second-highest trust signal after security certifications. Google's Search Central guidance on localised versions is the technical reference that every SaaS site should be auditing against. Skip the docs, ship a half-translated marketing site, and you forfeit the deal before sales calls. See our professional website translation page for the methodology we use on B2B accounts.

What it doesn't cover (and why that matters)

Most SaaS teams discover the gaps the hard way. Marketing-site translation alone is the most common scope, and it leaves four critical surfaces in English: the in-app UI strings, the transactional emails, the API documentation, and the help-centre articles.

In-app UI is usually owned by the engineering team via i18n libraries (react-i18next, vue-i18n, FormatJS), which is the right place for it but a separate workflow from website translation. Transactional emails — invoice receipts, password resets, trial-expiry warnings — are usually owned by the growth team and routinely missed. API docs and help-centre articles live in tools like ReadMe, Mintlify, or Zendesk, and each has its own translation workflow. The fragmentation is the actual problem. Without a single localisation owner running across all four surfaces, a French customer hits localised marketing copy on the homepage, English UI strings in the dashboard, an English invoice in their inbox, and an English help article when they search for "comment annuler mon abonnement". The trust break happens at the third inconsistency. Our scope on SaaS accounts always covers marketing-site, transactional emails, and the help-centre. In-app strings stay with engineering but we coordinate the glossary so terminology aligns.

The four-layer translation stack

Layer one is the marketing site: features, pricing, integrations, customer stories, comparison pages. This is the layer Google indexes and AI engines cite, so it needs the highest-quality native human translation with hreflang wired correctly. Layer two is the docs and help centre — high volume, lower per-page traffic, but heavy weight on conversion because trial users live in docs.

Layer three is transactional content: emails, in-app onboarding tooltips, error messages, billing pages. These need exact translation matched to your product UI terminology. Layer four is the in-app UI itself, which engineering owns but localisation governs via a shared glossary. We provide the glossary build and quality review across all four layers; engineering keeps source control. Recommended tooling: a TMS like Phrase or Lokalise for the engineering layers, structured CMS export for the marketing site, and our managed-service flow for docs. The Slator Language Industry Market Report tracks the full vendor landscape, and DeepL's translator documentation covers the machine-translation API quality benchmarks if you want to compare alternatives.

The 4-step launch sequence

Step one: lock the source-of-truth language and document feature naming. We call this the master glossary — typically 200-400 terms covering product names, features, pricing tiers, plan names, and core UI strings. Every translator works from this glossary, which prevents the "Workspaces vs Espaces de travail" drift problem.

Step two: native human translation of the marketing site, scoped page-by-page with feature-page priority first because those drive trial signups. Step three: docs and help-centre translation in parallel, prioritised by article view count from your analytics. The 80/20 applies: 20% of help articles handle 80% of search traffic, so we localise the top 20% first and queue the rest for monthly sync. Step four: continuous sync triggered by your product release cycle. We webhook into your CMS, docs platform, and email system, pick up changes, and turn around translated versions inside five working days. The benchmark on B2B SaaS accounts: trial-to-paid conversion in localised markets matches the English baseline within 90 days when all four layers are live.

Cost reality for SaaS-scale content

Self-managed SaaS localisation is expensive because the volume is high and the parity requirement is strict. A typical Series A SaaS marketing site with 60 pages plus 300 doc articles runs 80,000-120,000 source words. At freelance native rates of 12-15 pence per word that is £9,600-£18,000 per language for the initial translation alone, before TMS subscriptions, project management, and the ongoing sync work.

Our managed pricing for SaaS sits in the Scale tier: £1,997 activation plus £249/mo, covering 25 pages, 200 blog posts, and 75 doc pages per language. Most SaaS clients book Scale plus the four-language EU bundle. See website translation cost for the per-tier breakdown and translation cost per word 2026 for benchmark data. The decision usually comes down to whether you can dedicate a localisation manager full-time. If headcount is the bottleneck, managed wins. If you have a localisation lead, our service still cuts your team's time by about 60%.

When done-for-you wins for SaaS

Done-for-you wins for SaaS founders raising or scaling who need EU revenue ramped before the next round but cannot afford to hire a localisation lead. The four-layer coordination is the value: one named contact handles marketing, docs, emails, and the engineering glossary, with monthly sync that catches your release cycle.

It also wins when launching into French and German enterprise — the two markets where buyer expectations on localisation parity are highest. We document every translator's native qualifications, sign every page off, and keep an audit trail in your portal that satisfies enterprise procurement reviews. For SaaS clients also dealing with multilingual phone support, our sibling voice.eldris.ai ships AI receptionists that handle French, German, Italian, and Spanish callers natively. If your SaaS targets DTC ecommerce buyers in the EU, epr.eldris.ai covers their compliance side. To scope your specific surface area, contact us and we will return a fixed quote inside two working days.

Frequently asked questions

Do you handle in-app translation as well as the marketing site?

We govern the glossary and review native quality across in-app UI, but engineering keeps source control of i18n files. The reason: in-app strings are tied to release cadence and rollback risk that engineering needs full control over. Our role is the master glossary, native review of new strings as they ship, and quality QA. The marketing site, docs, help centre, and transactional emails sit fully in our scope.

How fast is your sync after a product release?

Five working days from receipt of new or changed source content to live translated pages, across all four layers in scope. Faster turnaround is available on Scale tier with a per-language sprint add-on. We webhook into your CMS, docs platform, and email system to pick up changes automatically rather than relying on manual exports.

What languages should a SaaS launch with first?

For B2B SaaS targeting Europe, the answer is almost always German first then French. German enterprise has the highest willingness to pay and the strictest expectation on localisation parity. French follows because France is the second-largest enterprise market in the EU. Spanish (Spain plus LATAM) is third. Italian and Dutch rarely pay back on their own and are added inside the four-language EU bundle.

What about API docs and developer-facing content?

API reference is a special case. Most enterprise SaaS keep API reference docs in English-only — the developer audience expects English source-of-truth and translation lag introduces accuracy risk. We localise the conceptual docs (getting started, authentication, rate limits) and leave the auto-generated reference (endpoint definitions, request schemas) in English. This is the SaaS industry default.

Do you handle the GDPR and privacy-policy translations?

Yes — we coordinate with your legal team on jurisdictional specifics. Privacy policies, cookie banners, terms, and DPA addenda all need native translation per market. Your legal team owns the source; we own the translated versions and version control on updates.
