Hi Nick,
Due to limitations on the QuickBooks side, it is not possible to change the properties of any core accounting fields in Method. In this specific example, QuickBooks allows 41 characters for the CompanyName field in its Entity table. We adhere to this limitation so to avoid any synchronization conflicts that might result from doing otherwise.
If you'd like, you could create a custom Method-only field to store longer Company Names. You could hide the QuickBooks CompanyName field on screen in Method and auto-populate it with the value from your custom field, truncated to 41 characters, using the Lose Focus event on your custom field. You could then use your custom field for reports, mailers, etc. and still have something that syncs over to QuickBooks.
Hope this helps.
