SaaS Localisation Strategy for Global Growth
Localisation and internationalisation are distinct but related disciplines. The technical and commercial requirements for expanding a SaaS product internationally, and how to architect for i18n from day one to avoid expensive retrofitting later.
Expanding Your Product to International Markets
SaaS localisation is the process of adapting a software-as-a-service product for a specific international market, including language translation, currency and payment method support, date and number formatting, legal and regulatory compliance, and culturally appropriate design and messaging. Internationalisation (often abbreviated i18n) is the underlying technical architecture work that makes localisation possible: structuring the application so that text strings, currencies, and formats can be swapped per market without rebuilding the core product. Most SaaS founders should design for internationalisation from the start (even if they only launch in one market initially) because retrofitting i18n into an application built with hardcoded English text and a single currency is significantly more expensive than building it in from day one.
International expansion is frequently the highest-leverage growth lever for a SaaS product that has achieved strong product-market fit and retention in its home market but is approaching saturation. A product that has proven its retention curve, its pricing, and its onboarding flow in one market often translates well to similar markets with comparatively modest additional investment, compared to the cost of finding an entirely new vertical or building a second product.
The Distinction That Matters
| Aspect | Internationalisation (i18n) | Localisation |
|---|---|---|
| What it is | Technical architecture enabling adaptation | The actual market-specific adaptation |
| When it happens | Built into the product from the start | Done per market, as you expand |
| Example | Storing all UI text as translatable keys, not hardcoded strings | Translating those keys into French, Spanish, German |
| Cost if skipped initially | Low — design decision, not extra build time | N/A — happens only when expanding |
| Cost to retrofit later | High — requires refactoring every hardcoded string and currency reference | N/A — localisation always has a per-market cost |
Beyond Translation
Language translation
Professional translation (not machine translation alone) of the UI, marketing website, email sequences, and help documentation. Machine translation can be a starting point for internal tools but customer-facing content should be reviewed by a native speaker familiar with the SaaS category’s terminology.
Currency and payment methods
Stripe supports 135+ currencies and many regional payment methods (SEPA in Europe, iDEAL in the Netherlands, Alipay in China). Displaying prices in the local currency and supporting the locally preferred payment method significantly improves conversion in international markets.
Legal and regulatory compliance
Data residency requirements (some countries require data to be stored within their borders), tax registration (VAT in the EU, GST in various countries), and consumer protection laws vary significantly by market and must be addressed before selling into a new region.
Date, number, and address formatting
Date formats (DD/MM/YYYY vs MM/DD/YYYY), number formatting (decimal commas vs periods), and address formats vary by region. A product that hardcodes US date formats will create confusion and errors for international users.
Cultural and design adaptation
Colour associations, imagery, and even the directness or formality of marketing copy carry different connotations across cultures. A direct, casual American marketing tone may underperform in markets that expect more formal business communication.
Localised customer support
Time zone coverage and, ideally, native-language support are increasingly expected by international B2B customers, particularly for higher-priced plans.

Stripe’s multi-currency support is foundational to SaaS localisation strategy.
The Practical Approach
Even if you plan to launch only in English initially, structure your Bubble.io application to support future localisation cheaply: store all user-facing text in a Language or Translation data type rather than hardcoding it directly into page elements, store all monetary values with an associated currency field rather than assuming a single currency, and use Bubble’s built-in date display formatting options rather than manually constructing date strings.
This upfront discipline costs very little extra development time (an hour or two of additional data model design) but saves a significant refactoring effort later if international expansion becomes a priority. SA includes internationalisation-ready architecture as a standard consideration in every Discovery Sprint, even for SaaS products launching in a single market initially.

Q: Should a new SaaS launch in multiple languages from day one?
Generally no, unless your initial target market is explicitly multilingual or your home market is small enough that a single-language launch would severely limit your initial customer base. Most SaaS founders should achieve product-market fit in one market and language first, then expand deliberately once retention and pricing are validated.
Q: How much does SaaS localisation cost per market?
Professional translation typically costs $0.10-$0.20 per word for the UI and marketing content, which for a typical SaaS product might total $2,000-$8,000 per language depending on content volume. Ongoing costs include maintaining translations as the product evolves and providing any localised support.
Q: Does Bubble.io support multi-language applications?
Yes, through a combination of native language switching plugins and a custom-built translation data structure (storing UI text as translatable database records rather than hardcoded text). This requires deliberate architecture design, ideally planned from the start rather than retrofitted.
