Fortnox error: 2000107

Description

Fortnox rejects the customer record because a field exceeds the allowed length. In this case, the value indicates that the customer name (Name) is too long.

Cause

• Name/customer name exceeds Fortnox’s maximum length.

• Duplicate concatenation in the mapping (e.g., store name + company name getting repeated).

• Unnecessary additions—such as parentheses, extra whitespace, or redundant words—make the string too long.

• Another field could be affected in rare cases (Address1, YourReference, etc.), but the error value here points to the Name field.

Resolution

• Reduce the number of characters in the Name.

• If you need to keep the full text: place a shorter version in Name and move the rest to a comments/notes field.

• Try the transfer again after correcting.
