Common errors
Contacts (customers, suppliers, and contractors)
The following errors can occur when posting contacts, including customers, suppliers, and contractors to Xero:
| First Name and Last Name are mandatory fields | If the card is an individual, then you must have both the First Name and Last Name fields completed before you can transfer the card into Xero. |
| Company Name is a mandatory field | If the customer is a company, you need to complete the Company Name field. |
| Customer / Supplier / Contractor status response from Xero is invalid |
Although it is possible a customer, supplier, or contractor transfer was successful, there was no valid response from Xero. You can verify whether or not the contact has posted successfully by accessing Xero. If it has, you can Mark data as exported. If it has not, try to post the transactions again. If the problem persists then please contact Simpro Support. |
| Duplicate found. Customer Invoice could not be posted to Xero |
There is already an invoice in Xero with the same invoice number. You can verify whether the invoice was already posted from Simpro Premium previously, or manually entered into Xero using the same numbering as Simpro Premium. |
