It was my first time working with transfer pricing, and the attention and follow-up were excellent and appropriate. Our corporate office in San Diego requested that we conduct a transfer pricing study. Previously, our company's accounting was handled by an external firm, and they were the ones who recommended Grupo Consultor EFE. This is our second consecutive year working with you, and so far, we have successfully completed our transfer pricing studies on time and in full compliance.
