Edit Customers in QuickBooks Online: Step-by-Step Guide

Start by logging in to QuickBooks Online and opening the Customers list. In my demo file I see two “Maple Renovations” records, while “Net Solutions” and “Net Fast” are really the same customer. Several profiles also lack email addresses or proper first and last names.

Launch SaasAnt Transactions from Apps › Find Apps. Search “SaasAnt Transactions,” click Get App Now—or hit Launch if it’s already installed—and choose your company.

Method 1: Download, edit, and re-import

  1. On the SaasAnt dashboard click Bulk Download › Let’s Export.

  2. Set Customers as the transaction type, pick a date range, and open Advanced Options for finer filters.

  3. Click Select. SaasAnt lists every matching customer; download the file as CSV or Excel.

  4. In the CSV add brightonbakery@gmail.com to Brighton Bakery, change display name “Net Fast” to “Net Solutions,” and make any other fixes. Save the file.

  5. Back in SaasAnt choose Modify › Let’s Modify, upload the edited CSV, review the preview, and click Update QuickBooks.

Method 2: Live Edit

Live Edit lets you update customers from inside SaasAnt without touching a spreadsheet. Click Ready to Edit and pick one of two options:

  • Edit by Searching – identify and select customers with advanced filters such as date range or amount.

  • Edit by Reference – pull specific customers by name or reference number.

We’ll use Edit by Reference. Enter multiple customer names—for example, both “Maple Renovations” profiles—and click Search. SaasAnt displays them side by side. Directly in the grid you can:

  • Add first name Mary and last name Jake.

  • Enter or correct email addresses.

  • Change the Currency Code.

  • Flip Active from True to False to inactivate a duplicate.

Press Submit and SaasAnt writes the changes to QuickBooks in seconds. A quick refresh in QBO shows the single active Maple Renovations profile with the new details.

Smart Rules to Prevent Future Duplicates

To keep new imports from creating more duplicates:

  1. Go to Smart Entry › Rules and click Create New Rule.

  2. Name the rule, set the type to Customers, and add a condition—for example, “If Display Name equals ‘Maple Renovations’, replace with ‘Maple Renovations Inc.’.”

  3. Save the rule. From now on, any file or app that tries a slightly different spelling will map to the existing customer.

You can build as many conditions as you need and modify nearly any field, saving hours of cleanup time.

Using rules to automate Customer management

Rules in SaasAnt Transactions are a feature designed to automate and customize the import process of financial data into QuickBooks.

How Rules Manipulate Data (Like Changing Customer Names)

Here’s the step-by-step process of how rules work for data manipulation, focusing on your example of changing customer names:

  1. Set Conditions:

    • You define a condition to identify when the rule should apply. For instance:

      • "If the customer name is 'Cust A'."

      • "If the customer name contains 'Doe'."

    • Conditions are flexible and can be based on any field in your import file (e.g., customer name, description, amount).

  2. Define Actions:

    • You specify what change to make when the condition is met. For example:

      • "Set customer name to 'Customer A'."

      • "Override customer name with 'John Doe'."

    • The action directly manipulates the data by replacing or modifying the original value in the import file.

  3. Apply During Import:

    • When you upload your file (e.g., Excel or CSV) to SaasAnt Transactions, the rule runs automatically. It scans each row, checks the condition, and applies the action before the data is sent to QuickBooks.

  • Example:

    • Import File: Customer name is "Cust A."

    • Rule: "If customer name = 'Cust A,' set customer name to 'Customer A'."

    • Result in QuickBooks: The transaction imports with "Customer A" instead of "Cust A."
