Audience

Owners and bookkeepers at small firms quoting catch up books

Core takeaway

Write the start month, the accounts, and what done means before you quote, reconcile oldest first, and stop when the file can join the monthly close.

A catch up job quoted from a phone call will expand. Six months behind is not the same as never reconciled, with a suspense account and no statements. Scope it on paper first. Then run the oldest month first, until the file can join the monthly close.

Bank work in Xero is bank reconciliation prep in Xero. Coding habits in QuickBooks Online are automating categorization in QuickBooks Online. Once this file is current, use the month end close checklist. Missing statements during the catch up are chasing bookkeeping receipts.

01

Scope it before you quote it

You need the last closed month (if any), the accounts in scope, and the documents that still exist. The IRS does not require a special recordkeeping system, but the records have to show income and expenses clearly enough to prepare returns and support what was filed. If the box of PDFs cannot do that, the catch up is a reconstruction, not a cleanup. Price and staff those differently. This page does not give prices. (Recordkeeping)

Scoping fieldWhy you ask
Legal name, EIN, entity type, cash or accrualYou are quoting one set of books, not a group of LLCs the owner mentions later
Software and who owns the subscriptionYou cannot clean a file you cannot open
Last month someone reconciled (bank, card, loan)That is the start date, not the date they hired you
Accounts in scope (every bank, card, loan, PayPal, Stripe)Unmentioned cards are how catch ups double
Payroll, sales tax, inventory, 1099 vendorsIn or out, in writing
What done meansReconciled through [Month], uncategorized at zero, ready for monthly close
What you will not doTax returns, a prior CPA's workpapers, inventory counts you cannot see

02

What you request on day one

Do not start coding until this list is either in the folder or parked with a date. Named chasing is the receipts guide. Here is the intake list.

  • Accountant access to the ledger, bank feeds, and payroll, or exports if they will not give access.
  • Statements for every in scope account for every month in the catch up, including the month before the first open month (opening recon).
  • Payroll registers and the four Forms 941 (or Form 944) for the years in scope.
  • Prior tax return PDF for opening equity, officer loans, and shareholder basis clues.
  • Loan amortization or year end statements.
  • A written list of owner draws, transfers between accounts, and anything they already know is sitting in suspense.

How long they should have kept those records is an IRS facts and dates question. Generally, records that support an item on a return stay until the limitations period runs. That is often 3 years after filing. Employment tax records stay at least 4 years after the tax is due or paid, whichever is later. Six years if they omitted more than 25% of gross income. Indefinitely if they did not file, or filed a fraudulent return. Property records stay through the year they dispose of the property. Do not tell them to shred a statement you still need for the catch up. (How long should I keep records?)

03

The cleanup order

Oldest open month first. If you start with last month, you will plug opening balances and then spend the rest of the job undoing it. Xero and QuickBooks both want a statement match, not a guessed cash number. The click of OK is the last step, not the first. See the Xero recon page and the QuickBooks categorization page for the product clicks. This is the order of work.

StepStop rule
1. Confirm opening balances against the last known recon or prior returnYou can explain cash, loans, and equity at the start date, or you have parked the break
2. Reconcile the oldest month's bank and cards to the statementsEach account is $0.00 difference or a named break
3. Repeat month by month, in calendar orderNo skipped months
4. Clear uncategorized, ask account, and clearing accountsEvery material amount has a category or a named client question
5. Suspense, undeposited funds, and stale outstanding checksEach item is aged, explained, or parked
6. Payroll, sales tax, and loan accounts if they are in scopeBalances match the registers or returns you were given
7. Owner draws, contributions, and related partyThey sit in equity or due to owner, not in meals
8. Accrual only: AR, AP, and prepaid if you were hired for themAging exists and the owner has seen it
9. Tie the period: profit and loss, balance sheet, recon reportsA reviewer can follow it
10. Hand off to the monthly close board for the next periodNext month has an owner and a close date

04

Uncategorized, suspense, then stop

Uncategorized income and expenses are not a style problem. They are amounts you cannot support. The IRS burden of proof is on the taxpayer to substantiate deductions. Your catch up does not invent receipts. You ask once, park with a date, and move. (Recordkeeping)

  • Write the client question as a line: date, amount, account, what you think it is, what you need.
  • Do not recode 400 Amazon lines as office supplies because the job is tired.
  • Suspense that is older than the catch up window, with no statement, is a parked item on the handoff, not a plug to make cash match.

Stop when the owner adds a second entity, inventory you cannot count, or three more years, and they want it inside the original scope sentence. Write a new scope. Stop when there are no statements and no feed for an account that clearly exists. You cannot recon what you cannot see. Stop when they want a tax position out of a cleanup. That is a tax engagement.

05

Hand the file to the monthly close

Cleanup ends when the next period can run on the month end close checklist. Write a one page handoff: last reconciled month per account, parked items with dates, feeds that still fail, questions the owner never answered, and the first monthly close date. The person who cleans up is not automatically the person who closes. Put an owner on that first close anyway.

If statements are still missing, keep using the receipt chasing emails. Do not invent a fourth cleanup email. The catch up is over. The monthly list has started.

06

Download the scoping worksheet

Download the bookkeeping cleanup scoping worksheet. Fill it before you quote. Copy the cleanup order onto the same job. Do not start month 1 until the request list is in or parked.
