QuickBooks Online Sync Issue: Character Limit Exceeded
Last updated on Aug 20, 2026
Why a field's length triggers this error
QuickBooks Online rejects the customer, invoice, or other record Maxio sends to it because one of its field values is longer than QuickBooks Online allows for that field. QuickBooks Online returns this as a Business Validation Error, and the message it sends back names the field, the character limit, and the current number of characters in the value.
Shorten the field's value in Maxio
Open the field named in the sync issue message in Maxio and shorten its value so it fits within the character limit that QuickBooks Online reported. The record syncs successfully on the next sync attempt once the value is within the limit.
How to avoid this sync issue
Keep field values within QuickBooks Online's character limits before you sync a record. Limits vary by field and by record type in QuickBooks Online, so if you are unsure how long a value can be, use the limit noted in a previous sync issue message for that same field as your guide.
