Accounting Clean Up & Backlog Bookkeeping Services
Our accounting clean up London service helps businesses bring overdue, inaccurate or disorganised accounting records back under control.
Accounting & Tax Associates Ltd can review historical bookkeeping, unreconciled bank accounts, duplicate transactions, suspense balances, VAT issues and incomplete records before accounts or tax returns are prepared.
Accounting Clean Up London Support for Businesses That Have Fallen Behind
Accounting records can become difficult to manage where bookkeeping has been delayed, bank reconciliations have not been completed or accounting software has accumulated errors over time.
ATA can review the position, identify the work required and establish a structured plan to bring the records up to date.
Once the backlog is resolved, the accounting process can move into regular bookkeeping, VAT, payroll and year-end reporting.

Does Your Accounting System Look Like This?
Many accounting problems build gradually. A few unreconciled transactions can eventually become hundreds of unexplained balances.
If the books no longer agree with the bank, VAT returns or year-end accounts, a structured clean-up may be needed before reliable reporting can continue.
QuickBooks, Xero & Sage Clean-Up Support
Cloud accounting systems can save time, but bank feeds, automation and imported data can also create errors when records are not regularly reviewed.
QuickBooks Clean-Up
Review bank feeds, duplicated entries, VAT coding, unreconciled transactions and balance sheet accounts.
QuickBooks ↗Xero Clean-Up
Review bank reconciliation issues, outstanding invoices, supplier bills and incorrectly posted transactions.
Xero ↗Sage Clean-Up
Review nominal ledger balances, customer and supplier accounts, VAT records and bank reconciliation issues.
Sage ↗Where bookkeeping has fallen behind, VAT returns may also become difficult to prepare or may have been completed using incomplete records.
Resolve Bookkeeping Problems Before They Flow Into VAT Returns
VAT reporting relies on the sales and purchase information contained in the bookkeeping system.
Where those records are incomplete or inaccurate, it may be necessary to resolve the accounting issues before reliable VAT reporting can continue.
Explore VAT Services →Is the Accounting Backlog Delaying Your Annual Accounts?
Annual accounts cannot be prepared reliably where key bookkeeping records remain incomplete or unreconciled.
We can review the backlog first, bring the records into a more reliable position and then connect the cleaned-up records to the year-end accounting process.

The clean-up should be approached in stages rather than making random corrections throughout the accounting system.

What Happens After the Accounting Clean-Up?
Once the records are brought up to date, the business can move into a regular accounting cycle rather than repeatedly falling behind.

Clean-up work is built around getting key accounting balances to agree.

Accounting Clean-Up FAQs
Common questions from businesses with overdue or disorganised records.
Can you catch up several months of bookkeeping?
Yes. We can assess the period outstanding and the available records before determining the scope of the catch-up work.
Can you fix a messy QuickBooks or Xero file?
Yes. We can review areas such as duplicate transactions, unreconciled banks, old balances and incorrect transaction coding.
Can you clean up accounts before annual accounts are due?
Yes. This is a common reason for accounting clean-up work. The records can first be reviewed and corrected before the annual accounts process begins.
What if VAT returns have already been filed?
We can review the accounting records and identify differences requiring further consideration. The appropriate VAT treatment will depend on the circumstances.
Can you fix old customer and supplier balances?
Yes. Customer and supplier ledger balances can be reviewed against invoices, receipts and payments to identify historic differences.
Can you review a director’s loan account?
Yes. Historical payments, withdrawals, reimbursements and other director transactions can be reviewed as part of the clean-up.
How much does accounting clean-up cost?
Clean-up work is normally scoped after reviewing the condition, volume and complexity of the accounting records because the amount of work required can vary significantly.
Can ATA take over the bookkeeping afterwards?
Yes. Once the backlog is resolved, ongoing monthly or quarterly bookkeeping can be arranged to keep the records up to date.
