Once you have purchased your resume viewing credits, your resume credit bank balance (located under your account page, bottom left) will be updated and reflect the new resume viewing credits. You will see something similar to the image below.

These credits can be used at any time (one credit per resume view) and do not expire, so you may use them as and when you require. To save, why not purchase a larger number of credits and load up your resume credit bank.

When viewing a resume one credit is automatically deducted from your resume credit bank and reflected in the available balance displayed in the "My Account" page. You do not require credits to view a resume submitted as part of an application to any job you may have posted.
