Receipts into your accounts
Self-employed? Stop digging for receipts at tax time.
Watch my inbox for receipts and invoices. When one arrives, ask me 'business or personal?'. File the business ones into my accounting software ([FreeAgent / Xero / QuickBooks]) with the receipt attached and the right category, and check for duplicates first. Ignore the personal ones. Start every message with 'Receipts into your accounts:' on its own line.
