Ensure new RPro clients who will be using the acctlink (especially with QuickBooks) use Customer and Vendor Codes that are Alpha instead of Numeric.
The reason is due to the fact that the link pulls the Code over and uses it for reporting. When a client runs an aging report, it would be more useful to see “ACME” versus “2347” which is meaningless.
Also, I’m not sure how many characters are available for the Code, but the more the better for this situation.
