FINANCIAL CONTROL, MONTH-END CLOSE

BOOKS CLOSE BY THE 10TH. NON-NEGOTIABLE.

QUICK ANSWER

The month end close deadline is the foundation of every financial metric we track. If the books don't close by the 10th, the WIP schedule is wrong. If the WIP is wrong, the P&L is wrong. If the P&L is wrong, the CEO Report is wrong, and every decision made from it's built on bad data. The 10th of the month close is the load bearing requirement of the whole financial control system.

Every number a subcontractor makes decisions with sits on top of a closed period. The WIP schedule needs the month's billings, costs, and percent complete updates before it can reconcile. The P&L needs the WIP entries before its revenue means anything. The CEO Report needs the P&L. So a close that slips to the 22nd doesn't delay one report, it delays the entire chain, and by the time the owner reads the numbers the month they describe is six weeks old. Late books don't produce late information. They produce wrong information, delivered confidently.

THE DEFINITION

WHAT IT MEANS.

The month end close is the process of entering, reconciling, and locking the prior month's books, and the deadline for it's the 10th of the following month.

The close is a weekly rhythm with a monthly finish line rather than a scramble in the first two weeks of the month. Transactions get coded as they come in, bank feeds get reconciled continuously, and cost approvals happen weekly instead of in a monthly batch. Built that way, the 10th stops being a stretch by the second or third cycle.

WHAT HAPPENS WHEN BOOKS CLOSE LATE

LATE BOOKS MAKE EVERY NUMBER WRONG.

01

The WIP schedule is stale or wrong

The WIP schedule needs the current period's billings, costs, and percent complete updates in order to reconcile. If the books aren't closed, some of those inputs are missing or estimated. A WIP schedule built on incomplete month end data produces overbilling and underbilling numbers that are wrong, which means the revenue recognized on the P&L is wrong too.

02

Double entries and unapproved costs distort the balance sheet

When books close late, transactions from the new period start mixing with the old one. Invoices entered before the prior period is reconciled create double entries, and AP that was accrued gets paid and entered a second time. The balance sheet accumulates distortions that take hours to unwind, assuming anybody finds them at all.

03

CEO Report data is unreliable

The monthly CEO Report pulls from closed, reconciled books. If the books aren't closed by the meeting, the owner is reviewing revenue, gross margin, and net profit built on incomplete data. Decisions made from those numbers, meaning hiring, equipment, and bidding, get made with bad information.

04

Bank reconciliation delays hide cash problems

A bank reconciliation that runs three weeks into the next month means the cash position is always built on old data. Outstanding items that should be caught in the rec, like duplicate payments, bank errors, and timing differences, persist for weeks instead of days. Cash management becomes reactive because the information is always behind.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

Ten days from month end to decisions

Books closed by the 10th means the CEO Report reaches you mid month, so revenue, margins, overhead, cash, and trends get reviewed while the month being reviewed is recent enough to act on. Books closed by the 25th means managing November with September's data. The deadline is about decision speed.

8 to 10 hours of reporting time, eliminated

A verified marine client at $25M ran its close in shared Excel, taking 8 to 10 hours to produce reports with one person as the single point of failure. A proper close system made the same reports instant, freed up the accounting function, and produced financials clean enough to unlock $10M in aggregate bonding.

$24K to $1.1M

A verified erosion control client at $5.2M was netting $24K with no monthly close worth speaking of: no per site costing, no WIP, and no trend data. The close discipline plus per site job costing took net profit to $1.1M the following year. That wasn't new work, it was the same work, finally visible month over month.

Concrete, the pour cost true up

The concrete close trues up ready mix invoices against pour tickets and yards billed. Supplier billing errors, overage charges, and short loads hide in the distance between what was poured and what was invoiced, typically 1% to 3% of material cost. On $1.5M of annual ready mix, the close discipline recovers $15K to $45K a year of pure billing error.

Civil, equipment and quantity reconciliation

A civil close reconciles equipment hours to jobs and field quantities to billed quantities. Unallocated equipment time and unbilled overruns surface at close, or they never surface at all. A civil sub that closes by the 10th catches a 2,000 yard quantity overrun in 40 days, and one that closes by the 25th catches it after the claim window has shut.

Electrical, the CO and T&M sweep

The electrical close includes a mandatory sweep of every directed change, every T&M ticket, and every revision driven scope delta from the month, each one confirmed billed or escalated. The trades that accumulate small changes need the monthly backstop most. The sweep is what makes the 48 hour change order protocol fail safe.

THE CLOSE SEQUENCE

TEN DAYS, IN FOUR STEPS.

Days 1 to 3, transaction cutoff and entry

All transactions from the prior month get entered and coded by the 3rd. Payroll, AP, AR, and job cost entries are in the system before the 4th. Any transaction not coded by the 3rd gets coded to the new period rather than backdated into the old one.

Days 4 to 6, bank reconciliation

The bank rec is complete by the 6th. Every account gets reconciled to its statement, meaning operating, payroll, and savings. Outstanding items get identified and resolved, and nothing moves forward without clean bank recs behind it.

Days 7 to 9, WIP reconciliation and adjustments

The WIP schedule gets updated with the current period's billings, costs, and percent complete. Overbilling and underbilling are calculated and recorded as balance sheet entries, and revenue gets adjusted to reflect completion rather than billing timing. The financial statements then reflect economic reality instead of invoice timing.

Day 10, books locked and CEO Report ready

The period gets locked, the financial statements are finalized, and the CEO Report data is pulled. The monthly accountability meeting can then happen in week two off a clean close. The deadline is built into the engagement as a standard deliverable rather than something the client has to manage.

Enforcement, upstream rather than at the deadline

We coordinate with the client's bookkeeper so transaction entry is current by the 3rd, we run the bank rec by the 6th, and we run the WIP reconciliation by the 9th. The client's job is to have transactions coded and approved. Ours is to close the books on time regardless of how disorganized the prior period was.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because every financial metric we track depends on it. WIP accuracy needs a closed period, the CEO Report needs accurate P&L data, and the 13 week cash forecast needs a current balance sheet. A close on the 22nd means the monthly accountability meeting happens with 22 days of stale data, and every decision made between the 10th and the 22nd gets made without current financial information.
It gets recorded in the current period rather than backdated to the prior one, because the prior period is locked on the 10th. Backdating creates reconciliation problems and destroys the period over period comparability that makes the 13 month CEO Report meaningful. A late transaction is a data quality question in the current period, and a closed period stays closed.
The close deadline is built into the engagement as a standard deliverable rather than something the client manages. We coordinate with the client's bookkeeper so transaction entry is current by the 3rd, we manage the bank rec by the 6th, and we run the WIP reconciliation by the 9th. The client's role is to have transactions coded and approved, and ours is to close the books on time regardless of how disorganized the prior period was.
It's impossible with the current process, which is the point. The 10th becomes achievable when the work moves upstream: weekly cost approvals instead of monthly batches, bank feeds reconciled continuously, job costs coded as they come in, and vendor invoices processed on receipt. We rebuild the close as a weekly rhythm with a monthly finish line, and by the second or third cycle the 10th is routine. A bookkeeper insisting it can't be done is describing the old workflow rather than the limit of what's possible.
By the 10th: all bank and credit card reconciliations, all job costs posted and coded, the WIP schedule updated with cost to complete by job, payroll fully allocated, and the draft P&L and balance sheet produced. What can wait: final CPA adjustments, depreciation entries that don't change a decision, and tax side cleanup. The dividing line is decision relevance, so anything the owner needs to steer the business makes the deadline and anything that only counts for the tax return can trail. The close serves the operator first and the IRS second.
