I am am accountant and several years ago I changed all my account numbers to match CRA account numbers for corporations (ie fertilizer is 9662). This makes is it easy to relate to Schedules on tax returns for clients. If they see fertilizer as code 9662 on their tax return and it matches their agexpert account numbers it's less confusing. I realize that this will likely never happen as it is a revamp of your whole system but it would be nice. Now I have to change all my numbers back to the archaic accountant numbering system.
