Home / Bookkeeping and monthly close / Books cleanup and catch-up
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
Illustrative screen. We explain every difference. We never plug one.
Two reasons companies ask for a books cleanup.
Different starting points, the same finish: books that tie.
Your books are months behind.
The bookkeeper left, the system changed, or the business simply outran the back office. One client came to us a full year behind. They now close every month.
- Missing months entered, period by period
- Every bank and card account reconciled
- Then a monthly close by business day 10
Your books are current, but you do not trust them.
The bank and the books disagree, receivables nobody can explain, a balance sheet line that has not moved in years. Bring us one number. We will find out what is behind it.
- A read-only review that lists what is wrong, in order of damage
- Every difference explained, never plugged
- No blame: we report what we found, not who got it wrong

Books cleanup results from our own engagements.
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.
