Complete guide
Everything you need to know
Software and App Localization in Belfast is an ISO 17100 certified end-to-end translation and cultural adaptation service that converts UI strings, SaaS platforms, mobile apps and app-store assets from en-GB into 150+ languages, priced from £30 per page in GBP, delivered same-day to Northern Ireland product teams.
What elements within software and apps require localization, including UI and app-store assets?
Twelve distinct layers require localization in a typical Belfast software or app project: UI strings, error messages, push notifications, onboarding flows, in-app purchase copy, help documentation, email templates, legal notices, app-store title and subtitle, keywords, screenshots and what’s-new copy. Each layer carries different file formats, tone requirements and quality thresholds, which is why a single ISO 17100 certified workflow that governs all of them is more reliable than managing each asset type separately.
| Layer | Assets localized |
|---|---|
| In-app UI | Strings, labels, buttons, error messages |
| Engagement | Push notifications, onboarding flows, in-app purchase copy |
| Support | Help docs, email templates, chatbot prompts |
| Legal | Terms, privacy notices, UK GDPR disclosures |
| App-store | Title, subtitle, description, keywords, screenshots, what’s-new |
| Website | Marketing pages, checkout, product data |
Which source files and formats are handled — iOS, Android, Node.js, PHP and web stacks?
Source files handled include iOS .strings and .stringsdict, Android strings.xml, Node.js i18next JSON, PHP gettext .po/.mo, React and Angular locale bundles, and XLIFF 2.0 — the interchange format that threads the continuous localization pipeline from GitHub through the TMS and back to the deployment branch. CMS exports from WordPress, Shopify and Drupal are also handled for website localization roundtripping. Every format is parsed and returned without disturbing code, placeholders or interpolation variables, preserving the engineering integrity of the source file throughout the localization cycle.
How are app-store listings and keyword localization handled for Belfast releases?
App-store listings for Belfast-originated releases are localized end-to-end across both iOS App Store and Google Play. Keywords are researched in the target language rather than translated literally from English, so ASO ranking survives — and often improves after — the language switch. Screenshots are rendered with locale-correct currency symbols, date formats and, where commercially relevant, Belfast City visual references. Push-notification tone is tuned by market: formal registers for Germanic locales, direct and concise for North American English variants. What’s-new copy is prepared and shipped alongside each release build so every locale receives the same feature narrative on launch day.
- iOS App Store and Google Play title and subtitle rewritten per locale for maximum keyword density.
- Keywords researched natively in each target language, not translated literally, preserving ASO performance.
- Screenshots rendered with locale-correct currency, dates and culturally appropriate imagery.
- Push-notification tone calibrated by market register and cultural expectations.
- What’s-new copy delivered alongside every release build across all active locales.
Are Irish language and Ulster-Scots strings supported for public-sector Belfast apps?
Irish (Gaeilge) and Ulster-Scots strings are fully supported for Belfast public-sector and consumer apps, delivered by native linguists working within the ISO 17100 TEP framework. The Identity and Language (Northern Ireland) Act 2022 formally recognises both languages and shapes the localization scope of public-sector digital services and consumer apps operating in Northern Ireland. Coverage of Irish and Ulster-Scots sits inside the broader 150+ language catalogue, meaning public bodies with language access duties and commercial teams targeting bilingual users in the region can commission both indigenous and international locales through a single workflow.
How it works
How much does software and app localization cost in Belfast, and how is it calculated?
Software and app localization in Belfast starts from £30 per page in GBP, where a standard page is defined as 250 words of source content. The total project cost is calculated by combining word count, language pair, technical complexity, file-engineering requirements and turnaround urgency. Same-day rush jobs covering up to 10,000 words carry a 25–50% surcharge on the base rate. Translation memory leverage reduces cost on repeat releases by discounting previously approved segments, which means a Belfast SaaS team on a continuous localization cadence pays progressively less per release as the memory matures.
| Item | Rate (GBP) |
|---|---|
| Standard page (250 words) | From £30 |
| ISO 17100 throughput | 1,500–2,000 words / linguist / day |
| Same-day rush (up to 10,000 words) | +25–50% surcharge |
| 75–99% TM match | 25–40% of new-word rate |
| 100% match / repetition | 10–20% of new-word rate |
| Certified translation stamp | From £25 per document |
What drives the price of a Belfast software localization project?
Six variables drive the final price of a Belfast software localization project. Word count of new source content is the primary cost driver, since the ISO 17100 workflow charges per productive word at the linguist’s throughput rate. Language pair is the second variable: rare or low-resource pairs such as en-GB into Icelandic, Welsh or Ulster-Scots carry a higher per-word rate than high-volume pairs such as en-GB into French or Spanish. File complexity and the engineering hooks required — placeholder protection, XLIFF round-tripping, CMS integration — add a project setup cost. Turnaround urgency applies the same-day rush surcharge. Certification requirements for legal, regulatory or App Store submission add a proofread and stamp fee. Finally, the volume of right-to-left, CJK or bidirectional layout work increases QA time and is priced accordingly.
- Word count of new source content — the primary cost driver.
- Language pair — rare pairs cost more than high-volume Western European pairs.
- File complexity and engineering hooks required for the source format.
- Turnaround urgency, including the same-day rush surcharge.
- Certification requirements for legal, regulatory or app-store submission.
- Volume of RTL, CJK or bidirectional layout work requiring extended QA.
How is translation memory used to reduce cost on repeat Belfast releases?
Translation memory stores every previously approved segment and automatically applies fuzzy-match discounts on subsequent releases. A Belfast SaaS team shipping fortnightly pays the full new-word rate only on genuinely new source strings, and a reduced rate of 25–40% on 75–99% matches, with 100% matches and repetitions charged at just 10–20% of the new-word rate. Over a full year of continuous localization, this compounding discount typically cuts the total localization spend by 30–60% compared with commissioning each release as a standalone project. The accompanying termbase keeps brand names, product terminology and regulated phrases consistent across every release, eliminating costly rework caused by inconsistent translation choices.
What is the turnaround time for a software or app localization project in Belfast?
Turnaround for a Belfast software or app localization project is governed by the ISO 17100 benchmark of 1,500–2,000 words per linguist per day. A single UI string file is returned within 24 hours, a 5,000-word product release takes approximately three working days, and same-day rush jobs handle up to 10,000 words at a 25–50% surcharge on the base rate. For teams on a continuous localization cadence, turnaround is rolling: every push to the source branch triggers automatic string extraction and routing through the pipeline, so translated builds return to the deployment branch in step with the engineering sprint rather than as a separate downstream activity.
| Job type | Volume | Turnaround |
|---|---|---|
| Certified UI string file | Up to 1 file | 24 hours |
| Product release | 5,000 words | 3 working days |
| Same-day rush | Up to 10,000 words | Same day (+25–50%) |
| Continuous localization sprint | Fortnightly cadence | Rolling, per push |
Turnaround is calculated from the point at which source files are confirmed as i18n-ready. Projects that arrive without externalised strings require an i18n audit first, which adds time before the translation clock starts. Pseudolocalization QA runs in parallel with engineering rather than after it, so layout and encoding bugs are caught before the translation stage and do not extend the delivery window. For Belfast fintech, cybersecurity and SaaS teams with hard regulatory or app-store submission deadlines, the same-day service — available on up to 10,000 words — provides a documented, ISO 17100 certified output that meets both speed and quality requirements simultaneously.
What tools and technologies power modern software localization — TMS, translation memory, AI and machine translation?
Modern software localization runs on five integrated tool categories: a translation management system (TMS) that orchestrates file routing and linguist assignment; computer-assisted translation (CAT) tools with translation memory that apply fuzzy-match discounts on repeated segments; a termbase that enforces consistent brand and product terminology across releases; machine translation with human post-editing for high-volume UI strings; and generative AI for app-store copy drafting and quality estimation. Every AI output passes ISO 17100 human revision before shipping — AI accelerates throughput but does not replace the two-linguist TEP gate required for certified delivery.
The continuous localization pipeline connects these tool categories in a single automated flow: a GitHub webhook detects a push to the source branch, extracts new or changed XLIFF strings, routes them through the TMS to the appropriate linguist queue, applies translation memory leverage on matches, and returns translated files to the deployment branch without manual file transfer. Pseudolocalization QA runs on each push, catching i18n regressions before human translation begins.
How is AI and generative AI used responsibly in Belfast localization projects?
AI is used in Belfast localization projects to accelerate machine translation post-editing, extract terminology from source repositories, generate app-store keyword and copy variants for human review, and score machine output quality before the revision stage. These applications compress the time between string extraction and first-draft delivery without bypassing the ISO 17100 human review gate. No AI output reaches a client’s deployment branch without being edited and proofread by a qualified linguist. Client source code and personal data are never fed to public generative AI endpoints; all AI processing runs within a closed, access-controlled environment covered by data-processing agreements.
- Machine translation with human post-editing on high-volume UI strings.
- Terminology extraction from source repositories to seed and maintain the termbase.
- Generative AI drafts of ASO keyword variants reviewed and approved by a native-speaker linguist.
- Quality estimation scoring applied to machine output before the revision stage.
How are source files and translation memories kept GDPR compliant?
Source files and translation memories are kept UK GDPR compliant through encrypted transfer over TLS, access-controlled TMS projects with role-based permissions, and data-processing agreements signed with every Belfast client before project commencement. A strict policy prohibits feeding client source code, personal data or proprietary product copy to public generative AI endpoints. Translation memory analytics and usage reporting remain inside the closed project environment. Clients retain ownership of their translation memories and termbases and can export or delete them at any time, consistent with data-subject rights under UK GDPR.

Sister city services in Manchester, Liverpool, Edinburgh, Glasgow, Leeds and Birmingham run under the same ISO 17100 workflow.
How can you get a quote for software or app localization services in Belfast?
To get a Belfast software or app localization quote, send source files or a GitHub repo link, the target locales and the release deadline. A scoped GBP quote referencing ISO 17100 TEP, translation memory leverage discounts and a turnaround SLA is returned the same working day. Pricing starts from £30 per page, with same-day rush capacity available on up to 10,000 words at a 25–50% surcharge for Belfast teams facing hard release or regulatory deadlines.
Quotes are structured to give Belfast product, engineering and marketing leads a line-item breakdown: new-word volume at the standard rate, fuzzy-match and 100%-match segments at their respective discount tiers, file-engineering costs, any rush surcharge, and certification fees where app-store or regulatory submission requires a stamped ISO 17100 output. This level of transparency allows teams to model localization spend against their release roadmap and adjust scope — language pairs, certification level or turnaround — before committing.
What information should Belfast product teams send with a quote request?
Belfast product teams should send five items with a quote request so that a fully scoped, fixed-price GBP quote can be returned the same working day:
- Source files or repo access — iOS .strings, Android strings.xml, Node.js JSON, PHP .po/.mo, XLIFF, or a link to the relevant branch of the GitHub repository.
- Target locales — the full list of languages required, including any Irish (Gaeilge) or Ulster-Scots requirement arising from the Identity and Language (NI) Act 2022 or internal product strategy.
- Release cadence — whether the project is a one-off release or a continuous localization integration tied to fortnightly or monthly sprint cycles.
- Existing assets — any brand glossary, approved translation memory or style guide already in use, so leverage discounts can be calculated accurately from the outset.
- Certification requirements — whether ISO 17100 certified output with a stamp is needed for app-store submission, regulatory filing or public-sector procurement.
