@yorkshiretea Thank you! It actually doesn't take much of my time at all.
I use Xero connected to all my bank accounts. Each transaction comes through a feed and it’s pretty easy to categorise them from there. I only bother to save receipts for deductible items. It takes me a couple of minutes per day to keep everything reconciled.
Every month-end, I spend an additional 5-10 minutes adjusting the market value of my portfolio, superannuation, other investments, grossing up my salary for tax, registering new assets in the asset schedule.
Xero is a double-entry bookkeeping system (the accounting method used by virtually all modern businesses). It gives me accuracy to the nearest dollar and certainty that I haven’t missed anything.
Most people will say this is overkill for personal finances, but in the long term, it is much easier and simpler to maintain than any other reasonably accurate method.
