Good bookkeeping isn't about doing more work, it's about doing small things consistently so year-end is calm rather than chaotic.
- Reconcile your bank weekly, not yearly
- Photograph receipts the moment you get them
- Keep business and personal spending separate
- Review who owes you money every month
- Set money aside for tax as you go
Do these and you'll claim everything you're entitled to, and never scramble for a lost receipt again.
