There are a few terms I can think of that might work, depending on context. One is “to audit”. Auditing usually refers to a formal process that accountants do to ensure that financial records are accurate. Another term is “to reconcile”, which means to make sure that one set of financial data/records matches with another. Another, less formal term is “to balance.” This refers to the process that most people do every month to make sure that the amount the bank says you have in your checking account is the same amount that you think you have. We used to say “I need to balance my checkbook” to describe this process, but people don’t use checkbooks so much anymore.

If you are counting physical items in a store or warehouse, it would be called "doing inventory" or "taking inventory". "double check" is a useful phrasal verb "After I entered all the numbers in the spreadsheet, I double checked them to make sure that they were all correct" There might be a specialized accounting term, but I can't think of one now.
