Why does Fishbowl say "QuickBooks can only handle 5 levels of Classes."?

QuickBooks enforces a 5-level maximum on class hierarchies (parent-child nesting). Your Fishbowl classes or a sync attempt exceeded this limit. Count the nesting depth of your class structure—if any parent-child chain goes deeper than 5, flatten it before syncing.

What it means

QuickBooks has a hard limit on how deeply classes can nest. You have a class structure in Fishbowl where a class has a child, which has a child, and so on—more than 5 levels deep. When Fishbowl tried to sync this to QuickBooks, QB rejected it because of the depth limit.

What to check

Review your Fishbowl class structure and count the nesting levels (Parent → Child → Grandchild, etc.). If any branch exceeds 5, consolidate by moving some classes to sibling level or merging them.
Confirm which account type or class group triggered the error—only those deeper than 5 need flattening.
This limit applies to QuickBooks only; Fishbowl itself has no such restriction.
