There's a certain elegance in formal business English that makes even simple phrases sound polished. 'As you directed' captures the essence of 仰せの通り while maintaining professionalism. I've found this particularly useful in corporate emails where acknowledging instructions needs to feel respectful yet concise.
Another variation I frequently encounter is 'Per your instructions,' which carries slightly more legal undertones. When working with international clients, 'In accordance with your guidance' sometimes fits better for complex projects. The nuance changes depending on whether you're confirming task completion ('Implemented as specified') or seeking clarification ('Proceeding as indicated').
