The Construction Month-End Close Checklist for Small Contractors

A month-end close in construction should tell you one thing: what is still open, what is safe to post, and what needs a decision before the numbers land in accounts.

When that is not clear, teams start leaning on inboxes, memory, and last-minute phone calls. That is how supplier invoices get parked, subcontractor claims arrive after the payment run, and job costs drift away from the live position.

A simple month-end close checklist gives you the same view every time.

Freeze the jobs you are closing

Pick the reporting cut-off and stick to it. List the jobs that are in scope, the cost codes that matter, and the people who can approve changes.

For each live job, ask:

• What has been ordered?
• What has been delivered?
• What has been invoiced?
• What has been approved but not yet posted?
• What is still awaiting a project manager, site lead, or QS decision?

If you cannot answer those questions quickly, the close will be messy.

Match POs to the real job cost

Purchase orders are only useful if they still reflect what was actually agreed on site.

At month end, check:

• PO value vs committed spend
• variations raised after the PO
• split invoices against one order
• invoices without a PO number
• work approved informally but not yet recorded

This is where small overspends hide. If the PO says one thing and the site reality says another, fix the record before the numbers go to accounts.

Clear subcontractor claims before they become a backlog

Subcontractor applications and partial invoices can sit in limbo for days if nobody knows who owns the next step.

For each claim, confirm:

• the claimed value
• the certified or approved value
• any retention held back
• any dispute or query
• whether the payment run can include it

If you are still chasing the paperwork at the point of the payment run, the close is already late.

Reconcile supplier statements and missing invoices

Statements are useful because they reveal what your inbox does not.

Use them to spot:

• invoices that were never received
• duplicate invoices
• credit notes that have not been posted
• delivery notes with no matching invoice
• lines that look wrong on quantity or rate

This is the fastest way to stop month-end surprises turning into next-month reversals.

Review committed cost, not just posted cost

Posted cost is backward-looking. Committed cost tells you what the job is already on the hook for.

A proper close should surface:

• open POs
• approved variations not yet invoiced
• subcontractor work in progress
• materials delivered but not billed
• plant hire still running

If committed cost is missing, margin looks better than it really is.

Check retentions and release dates

Retentions are easy to forget because they do not feel urgent until cash is tight.

At month end, make sure you know:

• what retention is held
• when it is due
• whether the release date depends on practical completion, defects, or a later milestone
• whether the record matches the contract

This matters for cash flow and for avoiding awkward calls later.

Decide what gets posted now and what stays open

The close should end with clear decisions, not more loose notes.

Each exception should fall into one of three buckets:

• post now
• query and hold
• carry forward with an owner and deadline

That is the difference between a close checklist and another inbox.
