Scaling accounting capacity with OpenAI

According to OpenAI Blog, Basis has built AI agents for accounting firms using a combination of OpenAI models: o3, o3-Pro, GPT-4.1, and GPT-5. The agents automate routine compliance and bookkeeping tasks, aiming to reclaim up to 30% of accountants' time. This allows firms to redirect effort toward higher-value advisory services and growth. For builders, Basis' approach demonstrates a practical workflow that orchestrates multiple specialized models within a single agent system, each potentially handling different subtasks such as reasoning or generation. The integration shows how professional services can leverage AI without full automation, augmenting human expertise instead. This pattern is relevant beyond accounting, offering a template for using multiple frontier models in domain-specific workflows.
