Excel Spreadsheet Tracking Yearly Accounting, Metadata, Formulas

I hope everyone is healthy and doing well, I have been tracking my accounting invoices/payments into an excel spreadsheet up until recently using Excel 2003 entering all the raw data and manually doing the totals, I just got Excel 2021 and would like to automate the process as best as possible and would appreciate anyone who could assist.

My header columns are as follows;

BANK DATE - INVOICE DATE - CHEQUE DATE - INVOICE # - CUSTOMER / SUPPLIER - CATEGORY - PRODUCT / DESCRIPTION - QUANTITY - $PRICE PER UNIT - $SUBTOTAL - $SHIPPING - $FEE EBAY - $FEE PAYPAL - $GST - $HST - $PST - $TOTAL - CURRENCY - BANK ACCOUNT - BANK BALANCE

I would like to add formulas to the spreadsheet that will generate monthly & yearly totals based on CATEGORY and other columns like CUSTOMER / SUPPLIER and PRODUCT / DESCRIPTION.

I really appreciate any help that would make my spreadsheet far more automated/useful for tracking then it currently is very tedious/manual.

Thanks!

I've attached a very condensed sample of the data I'm trying to sort with formulas, the main priority is to be able to AUTOSUM rows based on the "BANK ACCOUNT" "CURRENCY" "BANK DATE" "INVOICE DATE" and "CATEGORY", providing summaries monthly maybe placed on a separate worksheet. I did some searching on google I expect thousands of people have spent a long time making very complex accounting templates but so many results I was hoping to get some suggestions/help my best plan from the experts. Thanks again!

I apologize I understand why it would be important for any future users who may be interested in same question/answer to reference all related posts, honestly I posted the question in a bunch of forums to cast a wide net to hopefully assure best results. I have been looking at some premade templates but haven't located one that fits exactly my needs there are so many, hoping to find one which sorts/summarizes monthly & yearly debit/credit transactions for invoice date / bank date / category etc. I appreciate your understand of my ignorance. Thanks!
