Books cleanup and catch-up bookkeeping, until every number ties.

Months behind, or looking at numbers you do not trust? We rebuild your books period by period, reconcile every balance to a source document, and hand you books you can show a bank, an investor or an auditor.

  • Reconciled to source documents
  • A written quote before we start
  • NetSuite, QuickBooks, Sage or spreadsheets

What our books cleanup services include.

Six parts, from the first look to a clean monthly close.

Diagnostic

A read-only review and a plain list of what is wrong, in order of damage.

Bank and card reconciliations

Every account, every month, back to the last date that ties.

Receivables and payables rebuild

Subledgers rebuilt from raw data and matched to customer and vendor records.

Balance sheet cleanup

Every balance supported by a schedule, or cleared with your approval.

Catch-up bookkeeping

Missing months entered and closed, one period at a time.

Hand-over to a monthly close

A clean opening point, then books closed by business day 10.

How a books cleanup runs with us.

Small steps. Each period is closed and tied before we open the next.

  1. Week 1Diagnose

    We read your books with read-only access and list what is wrong. You get a written scope and quote within two days.

  2. ThenRebuild

    We enter what is missing and rebuild the subledgers from raw data.

  3. ThenReconcile

    Every balance is tied to a source document. Differences are explained, not plugged.

  4. ThenClose monthly

    You move onto a monthly close, with clean books behind you.

Books cleanup sign-off: what clean books mean to us.

We do not call books clean until all four of these are true.

Cleanup sign-off
  1. Every bank account reconciledTo the statement, for every month in scope.
  2. Every balance has supportEach balance sheet account is backed by a schedule you can hand to an auditor.
  3. Receivables and payables agreeWith your customers' and vendors' own records, not only with your ledger.
  4. Differences explainedNothing is plugged. If we write something off, you approved it and you know why.

Books cleanup results from our own engagements.

1,000+orders used to rebuild a receivables ledger from raw exports, line by line.
106 of 106invoices matched to the penny against the customer's own records, proving billing was never the problem.
~$23Kin checks that never arrived, traced to a wrong mailing address. 19 checks reissued with zero disputes.

Real engagements, anonymised. Figures are rounded.

When Hundred came along, our books were a year behind and our NetSuite was improperly implemented. They fixed both. Now we have a monthly close and better ERP operations.

1How far behind can the books be?

As far as they are. One client came to us a full year behind, with a NetSuite that had been set up wrong, and now closes every month. We work period by period, so the size of the gap changes the timeline, not the method.

2How long does a books cleanup take?

It depends on how many months are in scope, the number of accounts and the state of the records. After a read-only review you get a written scope with a timeline, within two days of the discovery call.

3What do you need from us?

Read-only access to your accounting system, bank and card statements for the period, and someone who can answer questions about unusual items. We do the rest.

4Will you tell us who got it wrong?

No. We report what we found and how we fixed it, never who was to blame. The goal is clean books, not a verdict.

5What happens after the cleanup?

You have a clean opening point. Most clients then move onto our monthly close by business day 10, but the books are yours and you can take them anywhere.

6What does it cost?

The price depends on your systems and volume. You can work with us on a project, monthly or hourly, and the discovery call ends with a written scope and quote within two days.
