Bookkeeper / Accounts Assistant

Keep a trades firm's books for a week: reconcile the bank to the penny, reconcile a supplier statement, chase overdue customers without losing them, prepare a VAT return that only reclaims what the rules allow, and close the month with accruals and prepayments.

What you'll build

Real portfolio pieces built during the course, not a certificate for its own sake. Each one is work you can show.

  • Bank reconciliationThe bank and the ledger brought to the same figure: timing differences explained, errors corrected with entries, and nothing left to a balancing figure.
  • Supplier statement reconciliationA supplier's statement matched to the purchase ledger: every difference found, what each needs, and the duplicate that must not be posted.
  • VAT return workingA quarter's VAT worked out and checked: output tax on sales, input tax limited to what valid invoices support, the amount due, and the deadline.
  • Month-end noteMonth-end adjustments that put costs in the months they belong to, and a short note for the owner on what was done, what is due, and what needs a decision.
