After a meeting, it is a good practice to write an e-mail to the client and let them know that you have understood their requirement and have a solution for it. Attach a summarized solution that you are proposing in a simple and easy to understand manner. Write to convey not to impress. Your message should be clearly conveyed.
Thank you for meeting with us the other day. It was an insightful session – giving us an opportunity to understand your business challenges and priorities.
As promised, we are now pleased to summarize [in the enclosure] the key action ideas we identified and discussed together, as well as our suggestions for what we consider to be a suitable course of action at this stage. Also please find attached our domain competency brochure.
Please feel free to call or e-mail if you require any further clarification, and if another meeting with our group would be helpful to you, do let us know.
Looking forward to a productive relationship…
