A client told me that I should add RT 0001 after my business number on my invoice for HST? How do I do this when select edit for the business number, it only accepts the 9-digit business number?
Good day, Lisa Milligan,
QuickBooks Self-Employed only lets you enter the 9-digit business number. You can add the extension number on the message section of the invoice.
Please let me know if there's anything else I can help you with.
