[Back](./) # How do I check if my client has viewed the estimate/invoice that I’ve sent him? If you’ve enabled the **customer portal** for your business in Zoho Invoice and configured it for your customers, they can view their transactions with you by logging into the portal. This includes viewing and accepting/declining estimates as well as viewing invoices. The client viewed estimates and invoices can be filtered for separate viewing, * Go to the estimate or invoice tab under **Sales** on the home page of Zoho Invoice. * Click on the drop down next to _All estimates_ or _All Invoices_ on the top left hand corner, and select **Client-viewed**. * You can now see only the estimates/invoices viewed by the client. ![Sort client viewed transactions](/invoice/kb/images/invoices/sort-client-viewed.png) Alternatively, you can simply click on the particular estimate or invoice and check if it has been viewed by the client. A tiny _eye icon_ on the right corner of the estimate/invoice page accompanying the words _Viewed_ suggests that the client has viewed it. ![Client viewed](/invoice/kb/images/invoices/client-viewed.png)
