Bookkeeping & Xero

Keeping the records straight, and getting Xero doing the work it should.

These answers provide general information, not advice tailored to your circumstances. Rules can change and exceptions may apply — speak to the CASS team before making a tax, accounting or financial decision.

You can do your own bookkeeping if you understand the records required, keep them current and are confident that VAT and accounting treatments are being handled correctly.

Do I need a bookkeeper and an accountant?Bookkeeping keeps the underlying financial records accurate and current. Accounting turns those records into statutory accounts, tax returns and other formal reporting.Read the full answer

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 do I reimburse myself for business expenses I paid personally?Keep the receipt, explain the business purpose and record the cost through the correct expense or asset account. For a company, record what it owes you before matching the repayment. For a sole trader, money taken back is usually drawings rather than a second business expense.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

How should I record customer deposits and payments received before work starts?Record the payment against the customer and contract, then check when it becomes earned income. Under accruals accounting, an advance payment is often held as a liability until the relevant goods or services are provided. VAT may become due sooner, so the two treatments need separate checks.Read the full answer

How should construction retention payments be recorded?A retention is an amount held back under the contract, usually until specified conditions are met. Track it separately from normal invoice balances and record its expected release dates. Revenue recognition, VAT and CIS each have their own rules, so the retention should not simply be treated as a discount.Read the full answer

Is Xero right for my business?Xero suits many small and growing businesses that want cloud access, bank feeds, invoicing, digital records and an accounting platform that can connect with other business apps. It's particularly useful when the business and its accountant need to work from the same live data.Read the full answer

What does a good bookkeeping service actually include?A good bookkeeping service keeps bank transactions, sales, purchases and expenses complete and reconciled. It should deal with the detail consistently enough that the numbers can be relied on rather than repaired at year end.Read the full answer

What financial systems should I put in place when starting a business?Start with a separate business bank account, cloud accounting software, a method for capturing purchase invoices and receipts, and a clear process for raising sales invoices and chasing payment. If you have staff, add payroll and pension processes from the outset.Read the full answer

What should I do if I suspect someone has accessed my accounting account?Act promptly. Use the provider’s official recovery process, secure the account from a trusted device and alert your IT support and CASS. Check for unauthorised changes, especially payment details. If money or personal information is affected, further reporting may be required.Read the full answer

What should Xero be set up to do for my business?Xero should have the correct business details, financial year, VAT settings, chart of accounts, bank feeds and opening balances. If those foundations are wrong, automation simply produces incorrect information more quickly.Read the full answer

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

When should I outsource my bookkeeping?If bookkeeping is regularly behind, evenings are being spent uploading receipts, VAT deadlines create a rush, or you no longer trust the figures in the software, the business has probably outgrown doing it informally.Read the full answer

When should I write off an unpaid customer invoice?Consider a write-off when there is evidence that an invoice, or part of it, is unlikely to be recovered. Being overdue alone is not enough. Check the collection history, disputes and customer circumstances, then record the decision correctly. Tax relief and VAT bad debt relief have separate rules.Read the full answer

Why is up-to-date bookkeeping important for business decisions?Bookkeeping that is six months behind can still produce annual accounts, but it can't help much with a decision today. Current records turn bookkeeping from an administrative task into the foundation for management information.Read the full answer
