Import your customers and suppliers list to QuickBooks

If you have a list of customers and suppliers you’d like to import, you can do so by following the steps below. This saves you from manually creating your customer and supplier records one by one.


Before you start, make sure that your excel spreadsheets are ready and in a format that is accepted by QuickBooks. You can download a sample here.


Things to look out for before you start


  • The file size limit is 2MB. We found that customers have the best experience when importing no more than 400 rows at one time. If there are more than 400 rows, we recommend that you split them into multiple lists and import them individually using the steps below.
  • Sub-customers can't be imported. Import sub-customers as customers and change them to sub-customers after the import.
  • If the file imported incorrectly and it needs to be re-imported, it does not overwrite customer/supplier records that have been created in QuickBooks, but it will be added to your customer/supplier list again.
  • The entries in the Name field must be unique. A supplier, customer, and employee can't have the same name.
  • The import only supports ONE email address--you can add others later.
  • Make sure that your file is in the format below:
    • Your column headers are in the first row.
    • Your spreadsheet is on Sheet1.
    • Your spreadsheet doesn't contain any formulas, charts or blank rows.
    • Your spreadsheet doesn't contain any errors (like #REF!, #NAME?, #N/A or #VALUE!).
    • Names don't contain colons (Smiley Happy or quotation marks (").

Map your fields to QuickBooks fields

This step is very important to make sure that you are mapping the fields in your spreadsheet to QuickBooks fields correctly.


The left column depicts the field names that QuickBooks uses and the fields in the right column is from your spreadsheet. To reduce errors, we recommend that you update the field names your excel spreadsheet before you upload your file.
