Why does Fishbowl say "No Sales Order was created. The specified SO number already exists. Try changing the order number and saving again."?

Your SO number is already in use. SO numbers must be unique across your system. Change the number to a new, unused one and save again. If you're duplicating an existing order, either let the system auto-assign the next number or enter a different number yourself.

Fishbowl: 'SO number already exists' — duplicate order number

What triggers it

You tried to save a sales order using an SO number that’s already assigned to another sales order in your system. This happens when:

You manually enter an order number that already exists
You duplicate an existing sales order without changing the number before saving
You edit an order and change its number to one that’s already in use

Why Fishbowl blocks it

SO numbers must be unique identifiers. Duplicate numbers would break order tracking, conflict with linked records like invoices and shipments, and produce incorrect reports. This rule keeps your data consistent and searchable.

What to do

Assign a new, unused SO number. If you’re duplicating an order, let the system auto-generate the next number or manually enter a different one. Check your existing orders to see which numbers are already in use. If you’re recreating a deleted order, give it a new number rather than reusing the original.
