Building an internal localisation team gives you control — but it comes with real fixed cost and hidden complexity. Here's an honest comparison of the two models, and how to work out which fits your volume, languages and budget.

As soon as a company starts shipping content in more than one or two languages, the same question comes up: do we build a localisation team of our own, or hand it to an agency? It is rarely a pure cost decision — control, quality, speed and language breadth all pull in different directions. Here is how the two models actually compare.
What “in-house localisation” really involves
The visible cost of localisation is the language work. The hidden cost is everything around it. A genuine in-house capability needs native linguists for each language you cover, revisers to quality-check them, project managers to keep jobs on track, and — for anything audiovisual — voice talent or a casting network, a recording booth, and an engineer. On top of that sit software licences for translation-memory, subtitling and terminology tools. Hire all of that and you have real control; you also have significant fixed overhead that has to be fed with work every month to justify itself.
The case for in-house
In-house shines in a specific situation: high, steady volume in a small number of languages. If you are constantly producing content in, say, English, French and German and the pipeline never really stops, salaried linguists who live inside your brand can be faster and deeply consistent. In-house also appeals when content is highly sensitive — unreleased financial, legal or security material — where some organisations prefer to keep everything behind their own walls.
The case for outsourcing
Outsourcing to an agency flips the economics: you pay per project instead of carrying fixed cost. That matters most when your volume is variable or seasonal, or when you work across many languages. No internal team can realistically hold native speakers of a dozen or more languages — but an agency maintains exactly that network, plus studios, engineers and project managers, and lends you the slice you need for each job. It is also how you scale fast: a product launch that suddenly needs twelve languages in three weeks is a non-event for an agency and a crisis for a small internal team.
The hybrid model most teams land on
In practice, the answer is often both. A very common and effective setup keeps strategy in-house — glossaries, tone of voice, approved terminology and a project owner who knows the brand — while outsourcing production: the translation, voice over, subtitling and dubbing. You keep control of consistency and brand without paying to keep a studio and a dozen linguists busy between projects.
How to decide
Four questions usually settle it. Volume: is it high and continuous, or variable? Language breadth: two or three languages, or many? Cadence: a steady stream, or unpredictable spikes around launches? Sensitivity: is the content so confidential it can't leave the building? Steady, narrow, high-volume and highly sensitive work leans in-house. Variable, broad, spiky work leans outsourced — and most companies sit closer to that end than they expect.
GoLocalise works as the outsourced production team for brands and in-house teams alike — translation, voice, subtitling and dubbing across 100+ languages, run by one project manager who keeps your terminology and tone consistent.
