My customer claims they paid an invoice amount different from what I received or I didn't receive any payment at all?

First, please confirm the payment date and details with the customer.  

Next, check your general ledger and bank statement to see if the payment is reflected.  

Some payments might be in process or not posted yet. 

You can also check the last sync between Centime and your general ledger.  

To check sync status, log in to Centime and click on the Sync Status icon at the top or far left toolbar.  

If the problem persists, please submit a ticket or contact the Centime customer success team via live chat (Mon-Fri 8 AM - 5 PM EST) or via email at cs@centime.com
