What exactly you don’t understand – Suspense is a ”junk” nominal code – usually during posting I put there items I don’t know what to do with them. For example when posting bank transaction I cannot find who paid, I don’t have a debtor to match with payment, so I would post it to Suspense to be able post my journal and later on I would investigate. It is temporary place to post things which require further investigation. For example I paid insurance as one amount but then need to allocate it to different departments. So my entry would be Cr Bank Dr Suspense, Then after doing some workings I would post Cr Suspense Dr Insurance Dep1, Dr Insurance Dep2. At the end of the period the suspense must be nil. So all items must be identified and re-allocated to right codes.
