"Localization is expensive" is a belief that often comes not from the actual cost of translation, but from the billing practices of traditional translation platforms.
This post breaks down how TMS pricing actually works, what costs are commonly hidden until you're already committed, and how to calculate the real cost before you start.
The Visible Cost: Translation Volume
Every TMS (Translation Management System) charges for volume in one of these ways:
Per-word pricing — You pay a rate per source word, either for AI translation or for human translation. Rates range from $0.02 to $0.30 per word depending on quality tier and language pair.
Per-key or per-string pricing — You pay per unique translation key in your project. This can be misleading: 10 languages × 1,000 keys = 10,000 strings billed, even if most are 2-word labels.
Seat-based pricing — You pay per team member with TMS access. This incentivizes restricting TMS access to "official translators," keeping engineers out of the loop.
Platform subscription tiers — A flat monthly fee for up to N words/keys/projects. The tiers are often designed so that growing teams quickly hit the ceiling.
The Hidden Costs
1. API call charges
Many platforms charge for API calls separately from storage. If your app fetches translations at build time or runtime via API, these calls add up — especially at scale or with frequent deploys.
Watch for: "API requests included: 10,000/month" — at 100K users loading translations, you'll blow through this in hours.
2. Seat costs for reviewers
You want your German marketing manager to review translations before publishing. That requires a TMS seat. Multiply by the number of language pairs you support and the number of stakeholders per language.
3. Integration fees
Some TMS platforms charge for integrations that should be standard: GitHub sync, Figma integration, Slack notifications. These are often gated to Enterprise tiers.
4. Machine translation costs
Many TMS platforms don't include AI/MT in the subscription. They charge per character through their MT provider, then add a margin. You might pay $0.02 per 1,000 characters — plus platform markup.
5. Project minimums and setup fees
Enterprise TMS vendors often require minimum commitments ($1,000-5,000/month) and charge one-time setup fees for custom integrations.
6. Storage and bandwidth
If you're delivering translations via CDN, some platforms meter storage and bandwidth separately.
7. Contract lock-in
The real cost of switching after 18 months with Platform X: exporting translations (if you can), converting file formats, rebuilding integrations, retraining the team. This is why pricing transparency matters upfront.
A Real Pricing Example
A mid-size SaaS company with:
- 5,000 translation keys
- 8 languages
- 10 team members (3 engineers, 5 reviewers, 2 translators)
- ~50K API requests/day (CDN delivery)
- GitHub sync needed
- AI translation for new content
On a legacy TMS (pricing intentionally obscured):
- Base plan: $299/month (5 seats, basic features)
- Additional 5 seats: $150/month
- API overages: $120/month
- GitHub sync (Enterprise only): Upgrade to Enterprise at $799/month minimum
- MT integration: $0.05/1000 chars × 2M chars/month = $100/month
- Total: ~$1,000/month
Plus: no native CDN, no mobile SDKs, 2-day support SLA.
On Better i18n:
- Pro plan: $49/month (unlimited seats, all features)
- API calls: included
- GitHub sync: included
- AI translation: included
- CDN delivery: included
- Native SDKs for Next.js, React, Expo, Swift, Flutter: included
- Total: $49/month
The 20x price difference isn't because Better i18n is undercharging — it's because the legacy model was designed for a world where localization was a slow, expensive, manually-managed process.
What to Evaluate Before Choosing a TMS
1. What's the true all-in cost at 3x growth? Model your costs at your current scale AND at 3x. Many platforms are affordable small but have pricing cliffs that punish growth.
2. Are integrations included or gated to Enterprise? GitHub sync, CI/CD integration, API access, and framework SDKs should be standard features, not upsells.
3. How is AI translation priced? Separate MT costs that aren't transparent upfront will surprise you at scale.
4. What's the seat model? Can all your stakeholders have access without per-seat charges? Reviewers, product managers, and QA testers should be able to access the TMS without ballooning your bill.
5. What happens if you leave? Can you export all your translations in a standard format? The answer tells you how much data lock-in is built in to the business model.
6. Is CDN delivery included? For modern web and mobile apps, runtime translation delivery via CDN is essential. If you have to build this yourself or pay extra, factor that engineering cost in.
The Right Question
The question isn't "what does this TMS cost?" It's "what does not solving localization well cost?"
Shipping English-only to a market that would adopt your product in their language is a real revenue cost. Delayed localization updates (because they require redeploys) are a real velocity cost. Engineering time spent manually managing translation files is a real labor cost.
The TMS fee is a small fraction of the total cost of localization. The right tool pays for itself many times over in speed, coverage, and reduced engineering overhead.
Transparent Pricing, Free to Start
Better i18n publishes all pricing publicly at better-i18n.com/pricing. No enterprise tiers that require a sales call. No surprise overages designed into the billing model. Free tier that's actually usable, not a crippled trial.
