+Crowdin offers a range of additional services that can significantly improve your localization workflow while simplifying payment and service management. These services are managed directly through your Crowdin account using a dedicated balance separate from your primary subscription. This means you don't need to register additional accounts to access MT engines, AI models, or translation vendors, such as Crowdin Language Services. By consolidating payments in one place, you gain greater control over your localization resources and expenses, ensuring seamless workflow integration.
+
+## Available Services
+
+Crowdin can manage the following paid services:
+
+- **MT engines** (e.g., DeepL Pro)
+- **AI models** (e.g., OpenAI, Google Gemini, and other providers)
+- **Translation vendors** (Crowdin Language Services)
