Who this decision is for
- A SaaS product manager at an overseas company weighing whether to translate the marketing site only or also the trial and help centre for Korean users.
- A growth lead whose English-language self-serve funnel gets occasional Korean sign-ups and who suspects language is limiting activation.
- A SaaS founder planning Korea entry who must decide how much product localisation is needed before marketing can be judged fairly.
- A marketing manager at a global software company asked to justify Korean pricing display and payment friction to product and finance teams.
The decision to make
The decision is where localisation effort goes before or alongside marketing. SaaS buyers do not only read a homepage; they try the product, check documentation, look at pricing and search for reassurance. If any of these stays in English only, marketing traffic may arrive and stall. The choice is which touchpoints to localise first and which to leave in English for now.
The trade-off is cost against conversion clarity. Full product translation is a large commitment that may not be justified before demand is tested. A lighter path localises the marketing site, key documentation and onboarding emails, and keeps the interface in English with a clear note. That lets you learn from real Korean users before committing further. Product and marketing teams must agree on the boundary.
Options compared
| Option | Best when | Watch out for |
|---|---|---|
| Korean marketing site plus English product | Your users are technical, comfortable with English interfaces, and you want a low-cost way to test Korean demand. | Non-technical buyers may drop off at the English trial; onboarding needs Korean guidance to compensate. |
| Korean site, documentation and onboarding | You need self-serve activation and support deflection, and can maintain documentation updates over time. | Documentation goes stale quickly; assign ownership or Korean pages will contradict the product. |
| Full Korean product interface and marketing | Korean demand is confirmed and the product serves buyers who expect a fully Korean workflow. | Highest cost and release complexity; requires engineering commitment and ongoing translation management. |
Risks to manage
- Trial dead ends. Korean visitors reach an English-only sign-up or verification email and leave. Walk the whole trial path as a Korean reader and fix or explain each friction point.
- Pricing confusion. Prices, currency, tax handling and invoicing may be unclear to local buyers. Confirm billing and tax questions with qualified advisers and state plainly what the page shows.
- Borrowed proof. Global logos and reviews may mean little locally, and implying Korean customers you do not have is misleading. Show only genuine evidence and label its origin.
- Support gap. Marketing attracts questions that arrive in Korean. Decide who answers, in what hours and language, or set clear expectations on the site.
Evidence to gather first
- A screen-by-screen map of the signup, trial and onboarding path, marking every place text, email or payment is not Korean-ready.
- Search and support data showing which product questions users ask, useful for choosing which documentation to localise first.
- Any existing Korean users or customers, with written permission to reference them, and feedback on why they chose the product.
- Your product roadmap for language support, so marketing promises match what engineering will actually ship.
Recommended process
- Journey audit. SWIN reviews your funnel from search to activation as a Korean visitor would, noting language gaps, trust gaps and friction points, and ranks them by likely impact.
- Localisation scoping. With product and marketing, we agree what is translated, what is adapted and what stays English, and document the reasoning so it can be revisited later.
- Korean content build. Product pages, use-case pages, onboarding copy and priority help articles are written natively, with terminology checked against a shared glossary.
- Search and channel setup. We prepare Korean search presence and any paid or partner channels, pointing each to a page that matches the visitor's intent.
- Learn and adjust. Together we review activation and support questions from Korean users, then decide whether to deepen localisation or refine messaging.
