Here’s how our typical software localization process looks like

This process is valid for ~80% of our localization projects. If it doesn’t fully fit your task, let’s discuss it and design your own localization workflow!

É enviado um pedido preliminar
Write to us at or submit a preliminary order form along with links to your cloud project and the product.
É atribuído um gestor de projeto
O gestor de projeto é responsável por preparar o glossário e o orçamento, por acompanhar as datas de entrega, e por ajudar ao longo do projeto.
Os tradutores começam a trabalhar
O gestor de projeto reúne uma equipa com os melhores linguístas para o projeto.
O contexto é discutido
A comunicação acontece na plataforma de nuvem; a memória de tradução e o glossário garantem a consistência da tradução.
A revisão é feita por um tradutor independente, que verifica possíveis erros e garante a precisão da tradução.
Localização contínua
É compilada uma versão localizada do conteúdo
Essa fase ocorre após a transferência do texto localizado a partir da plataforma de localização, ou diretamente na plataforma através da funcionalidade de compilação automática por CLI (interface de linha de comandos).
A localização é testada
O controlo de qualidade da localização garante que o texto traduzido aparece corretamente.
Eliminação de erros menores
As correções são feitas imediatamente ou reportadas diretamente aos desenvolvedores no formulário de erros.
São adicionadas novas linhas de texto

All-in-one software localization services

Software localization testing

Depois de compilada a versão traduzida da app, um especialista em localização faz um teste na versão local correspondente do sistema operativo. During linguistic testing, the tester takes screenshots of problem areas (untranslated text, strings that go off-screen, wrong encoding or text direction, wrong context) and works with the developer to make changes to the resource files. If you have already translated your app yourself or through an outside provider, you can still use our linguistic testing service. Learn more about our localization testing services or request a quote.

Translation of small texts

Over time you will accumulate new articles, case studies, news, and press releases, and these too will need to be translated. For translating this kind of textual content, try Nitro — an online professional translation service. This service can also be useful for technical support, when clients need a response in their native language. We designed Nitro especially for text translation online within just a few hours, without the need for managers or excessive correspondence. Just register with Nitro, so that you’ll be able to place an order in minutes when the need arises.

Localization of audio and video

Alconost Video creates videos about software, online services, and websites — but we do more than that. Our team localizes video and audio content as well. If your project needs voice-overs in a new language — or you need to localize — we know exactly how to get it done.

Localization languages and rates

Traduzimos para mais de 100 idiomas, incluindo os mais populares (Inglês, Chinês, Japonês, Alemão, Francês, Espanhol), para os mais raros, e até mesmo para dialectos.

Podemos encontrar um tradutor para quase todos os idiomas necessários para o cliente, consoante o produto e os objetivos. Às vezes, a localização em idiomas de nicho pode oferecer melhores perspetivas do que a localização em idiomas convencionais. Please, request a quote to get an estimate of your project.

Caso algum idioma raro não esteja na lista, podemos ajudar na procura e na contratação de linguistas.

Professional software localization tools and translation management platforms (TMSs)

Crowdin — our first-choice localization platform

Cloud-based translation platform Crowdin allows localization projects to be managed in real time. You can:

  • Upload string resources in any format (.resx, .po, .strings, etc.) either manually or through the API
  • Appoint translators and editors
  • Track the translation and editing process for your project
  • Leave comments and discuss questions directly with the translators and editors
  • Create glossaries
  • Manage the translation memory
  • Export string resources once the translation is complete

We also work on other localization platforms, such as GitLocalize, Phrase, Lokalise, Memsource, Memoq, Smartcat, Webtranslateit, Transifex, OneSky, POEditor, Trados, and many more.

How our software localization management works

With Alconost, your localization project will be run by a dedicated project manager, who:

  • Studies your material and the specific features of the text in depth
  • Agrees on the price, taking repetitions into consideration
  • Chooses a team of translators and editors with the necessary specialisms
  • Controls deadlines
  • Takes care of quality, formatting and consistency of the completed translations
  • Maintains the glossary and translation memory
  • Organizes linguistic testing
  • Prepares all the accompanying documents required (agreement, invoice, PO)
  • Is available practically 24/7 to answer any of your questions

Your Project Manager is your “single point of contact”, who you can resolve all your questions with regarding the project. If your Project Manager becomes unavailable for some reason, another Manager will replace them straight away at the same address.

We have approximately 700 professional native-speaker translators in our team, with a broad range of specialisms. We always try to assign one or several dedicated translators to your project and work specifically with these translators on a continuous basis. This is useful if you have a large project that is periodically updated, you need to use consistent terminology, or you simply like a particular translator's style. If the translator changes for some reason, they will hand over the glossary and translation memory to the new translator to ensure consistency of terminology and style in future updates.

Translation memories and glossary

Translation memory is a database that stores the translation of each segment of text. It allows you to automatically translate repeated words, phrases and sentences.

Translation memory allows you to:

  • Increase the performance of the translation team
  • Ensure consistency of terminology across a whole project
  • Improve the quality of translation
  • Change translators partway through
  • Save time translating repetitions

Each client’s account has its own, confidential translation memory. All data is stored completely securely. A glossary is a special dictionary with definitions, translations and usage examples for terms used in a text. This dictionary can be imported into an automatic translation tool to expedite the translation process and ensure consistency of terminology across one or more texts. A glossary makes it possible to assign several translators to a project and change translators around during the process if necessary.
