Why are the Received Payments Not Syncing to QuickBooks?

In order for a received payment issued on an invoice in ClickClaims to synch to QuickBooks, it must meet the following conditions:

• Payment must have been issued within the past 30 days.
• Only 40 records can be processed by Intuit's QuickBooks Web Connector service at a time.
  • If you're attempting to sync more than 40, the first run will only process the first 40, and then you must run the Web Connector again as many times as needed to process all eligible records.
• The associated "Client" record must be "Active" and flagged as "Sync to QuickBooks" in ClickClaims.
• The associated "Client" record must be synched to QuickBooks already.
• The Accounts Receivable account must already be synched from QuickBooks to ClickClaims.
• The payment record has not yet been synched to QuickBooks, if applicable.
• The payment record has been modified since the last synch to QuickBooks, if applicable.
  • It will look for a matching check # (reference #), client, and payment amount.
    • Use a unique check # (reference #), as applicable.
