Do I still need an accountant if I use Xero?Xero records, organises and reports financial data. An accountant checks the treatment, deals with tax and statutory obligations and helps interpret what the figures mean.Read the full answer

How should I reconcile cash takings and till differences?Reconcile recorded sales to the cash counted, card settlements, refunds and other movements. The amount banked is not always the day’s sales. Keep a clear cash record and investigate differences promptly instead of changing sales figures simply to force the till or bank reconciliation to balance.Read the full answer

It's particularly useful when the business and its accountant need to work from the same live data.Read the full answer

Xero uses established security measures, but users must also protect their accounts with strong passwords, multi-factor authentication and sensible access controls.

When should I issue a credit note rather than edit or delete an invoice?A credit note usually records a genuine reduction or cancellation of an issued invoice while preserving the original transaction. The right action depends on what changed, whether payment or VAT reporting has happened, and whether the document is still a draft. Keep a clear audit trail.Read the full answer
