As I understand things currently to do a % price increase across all Items requires export of Item data as a txt file, make adjustments to prices in Excel, then re Import back into MYOB. This is quite complex for many users and from my experience not a smooth, simple or seemless process. I experienced data errors and required considerable time and support from MYOB suport staff. MYOB should have a price adhjustment "Wizard" to manage this process which is a common requirement in any accounting system and handled far better by other Desktop based accounting software packages. (eg. Pastel Partner/Sage).
