I needed to change my online accounting software to another platform. I asked Neha at Sum and Substance about moving to Xero. She made the process so easy. She offered excellent training that was easy to understand and was available when i needed extra advice and assistance. Neha is generous with her time and exceptional with her knowledge and training. i would highly recommend Neha at Sum and Substance.
