I'm setting up this year's accounting ledger for a sole proprietorship. It used to be done by CPAs in the past but I decided it's time to bite the bullet and start doing it myself.
All is going well, except for how to include last year's balance sheet and profit and loss items in this year's bookkeeping. Typical items would be fixed assets, depreciation, loan payable to shareholder, deficit... I don't want to have to redo 10 years worth of bookkeeping just to recover them, so how would you create double-entry items for them in this year's ledger?
I'm using GnuCash but a general answer that can be adapted to any spreadsheet or personal accounting software would be appreciated/preferred.
