Closing the books is one of those things that seem straightforward. But for many finance teams, this couldn’t be further from the truth. 

More often than not, month-end close becomes a stressful, high-stakes scramble marked by tight deadlines, incomplete data, and missing approvals. A process that seems simple on paper takes six days or more for over half of finance teams. 

While organizations feel the pain acutely, they often shrug it off as inevitable. Finance teams power through chaotic closes month after month because they don’t think they have any other option. 

But here’s a little secret: there is a better way. 

When organizations take a structured approach built around a clear checklist and the right systems, month-end close becomes faster, cleaner, and a whole lot less painful. Instead of scrambling in the eleventh hour, teams stay in control from start to close. 

In this post, we’ll walk through a practical month-end close checklist you can start using right away to pave the way towards a smoother, more accurate close every single month. 

Why month-end close is so hard for AP teams

There are a few common reasons why closing the books becomes a longer, harder process than it needs to be. 

Invoices sneak in past the cutoff

Invoices keep coming in as the cutoff approaches, and they’re not always processed or approved in time. This leaves AP teams chasing down last-minute approvals or making stressful judgment calls. 

Undiscovered errors turn into major problems

When data is keyed by hand, errors are inevitable. These errors can fly under the radar until the final stretch, at which point they’re harder to fix and a lot more disruptive. 

No real-time visibility into what’s outstanding

When teams don’t have real-time visibility into what’s outstanding, they’re forced to cobble together information from spreadsheets, inboxes, and disconnected systems. And often, there’s conflicting data across systems. 

Approvals hold up the process

When approvals are routed manually, they often get stuck in inboxes. This holds up the entire process and leaves teams scrambling at the end of the month. 

Disconnected systems that don’t talk play well together

Disconnected tools and workflows require manual handoffs to keep things moving forward. And reconciliation between siloed systems means more manual work for AP staff. 

Teams are at capacity 

All month long, AP teams are bogged down with growing invoice volume, endless vendor requests, and countless process issues. By the time month-end rolls around, they’re stretched to the max with little time left to catch up when something inevitably falls behind.

What a clean month-end close looks like 

Before diving into the month-end close checklist that can turn everything around, let’s first explore what a “good” close really looks like. 

In a well-run close, nothing important is left until the last minute. Every invoice is captured, coded, and approved before cutoff, and teams don’t have to put in extra hours chasing down missing details. Accruals are accurate because teams have real-time visibility into what’s been received but hasn’t been processed yet. As a result, there are fewer last-minute surprises.

During a clean month-end close, reconciliation is a straightforward validation step that takes hours instead of days. Instead of digging through disconnected systems to find and resolve discrepancies, data is always aligned, enabling leadership teams to make informed decisions.  

While high-stress closings have become the norm, they don’t have to be for your organization. With the right structure, your AP close process can become more controlled, predictable, and much easier to manage. 

The AP month-end close checklist

A better month-end close doesn’t just happen by chance. It’s the result of consistent, proactive work in the weeks leading up to it. 

This end-of-month accounting checklist breaks the process down into three phases: one week before, 48 hours prior, and post-close. Use it as a guide to stay one step ahead of issues, rather than reacting to them in the eleventh hour. 

Phase 1: One week before close

The goal of phase one is to identify and resolve issues early on. This eliminates last-minute blockers and sets you up for a smoother close. 

1. Review all open invoices 

Identify any that are at risk of missing the cutoff. This gives you time to resolve issues before they become bottlenecks.

2. Follow up on outstanding approvals

Send reminders to approvers with outstanding invoices in their queue. This will reduce the amount of time finance teams must spend chasing down last-minute approvals. 

3. Reconcile vendor statements

Confirm all vendor statements have been received and reconciled against your records so nothing is missing or duplicated. 

4. Flag any discrepancies or exceptions 

Identify invoices with issues such as missing POs, discrepancies, or duplicates. Addressing these now prevents delays and stressful judgment calls later on.

5. Verify new vendor setup and coding

If you’ve added new vendors during the month, make sure they’re properly set up in the system and correctly coded. This will help you avoid reconciliation errors that can slow things down. 

Phase 2: 48 hours before close 

In phase two, teams should focus on ensuring everything is complete, accurate, and ready for a smooth cutoff. 

6. Confirm all invoices are approved or escalated 

By this point, nothing should be sitting idle. Now’s the time to escalate any remaining approvals so they can be resolved before cutoff.

7. Run a final duplicate check

Four in 10 finance teams have experienced overpayment in the past year. Run a final duplicate check across the period to prevent this from happening.

8. Capture accruals 

Ensure all accruals are captured for invoices received but not yet processed so you can be sure liabilities are accurately reflected. 

9. Verify coding accuracy 

Confirm all invoices are accurately coded to the appropriate accounts and cost centers. Doing this now will save you a lot of rework later. 

10. Confirm payment runs 

Check that payment reminders have been scheduled or completed for all outstanding invoices. This helps prevent payments from accidentally falling into the next period. 

Phase 3: Post-close 

The work doesn’t stop after the books are closed. Checking off these important post-close tasks helps ensure everything is validated and documented, and you’re set up for an even smoother close next month. 

11. Reconcile AP sub-ledger to the general ledger 

Validate that AP balances align with the general ledger. This enables you to confirm the integrity of your financial data.  

12. Document any exceptions and resolutions

Doing so provides a clear audit record and can help the team identify areas for process improvement.  

13. Pull a final aging report

Review this report to identify any outstanding invoices that need attention going into the next cycle. 

14. Archive period records for audit readiness 

Store all invoices, approvals, and supporting documentation in a centralized, well-organized system of record. 

15. Document recurring issues 

Look for patterns in issues and their causes. This can help you optimize your processes before the next close. 

The biggest close killers (and how to stay one step ahead)

You’ve ticked off every item on the accounts payable month-end close checklist. But things still don’t go quite as smoothly as you hoped. Why? Because certain issues have a way of sneaking in and derailing the process. 

Here’s a look at some of the most common close killers and what you can do to nip them in the bud. 

Late approvals

When invoices sit in approval quotes for too long, they create major bottlenecks and force AP teams to chase people down. 

How to prevent it

Establish internal deadlines before the close date and automate reminders so approvers get a nudge before minor delays turn into bigger problems. 

Missing invoices

At many organizations, invoices are scattered across inboxes, shared drives, disconnected systems, and even physical printouts. This makes it easy for invoices to go missing, which can create blind spots at month-end close. 

How to prevent it

Centralize invoice intake into a single, connected system. Every invoice will be captured and processed in one place, reducing the likelihood of slipping through the cracks. 

Coding errors

Incorrect GL coding errors often go unnoticed until reconciliation, at which point they’re time-consuming and disruptive to fix.

How to prevent it

Establish standardized coding rules and enforce them at the point of entry. You’ll prevent errors instead of needing to go back and correct them during close. 

Manual reconciliation

When teams rely on spreadsheets and manual checks, reconciliation becomes a tedious, multi-day process that slows things down and burns people out. 

How to prevent it 

Create real-time visibility into AP so balances stay aligned throughout the month. Reconciliation will be a straightforward process that takes hours instead of days. 

Accrual gaps

Missed or inaccurate accruals lead to incomplete financials and last-minute adjustments.

How to prevent it

Build accrual review into phase one of your month-end close checklist, not phase two. That way, liabilities are accounted for in advance. 

How AP automation transforms the close process 

A month-end close checklist is a useful tool for eliminating friction and ensuring you’re taking the right steps to set yourself up for success. But while a checklist can help build consistency, it can’t eliminate the manual work that often stalls month-end close and introduces risk. 

That’s why more and more companies are turning to accounts payable automation. 

A strong AP platform streamlines or automates most of the items included in the month-end close checklist we walked through earlier. For example, invoices are captured and coded at the point of entry instead of being manually keyed in later. Approvals are automatically routed to the right people and tracked in real time so they don’t get lost in inboxes. And duplicate invoices are flagged early on before they cause downstream problems.

The right platform provides teams with a single, real-time view of their AP data. As a result, reconciliation becomes a straightforward task rather than a tedious investigation project.

As previously stated, more than half of finance teams spend six days or more closing the books each month. A large portion of that time is spent on time-consuming manual work such as chasing approvals, correcting errors, and reconciling disconnected data. 

AP automation reduces both the time required to close and the risks associated with manual processes. 

AP platforms like Ottimate support a cleaner, faster month-end close. Invoice capture, coding, approvals, and reconciliation all come together in a single workflow that transforms month-end close from a reactive, chaotic process into one that’s structured, accurate, and predictable. 

Ready for a smoother, pain-free month-end close? 

Month-end close seems straightforward in theory. But in practice, it’s a common source of stress for finance teams across industries and company sizes.

Fortunately, a smoother month-end close is within reach, and it doesn’t have to mean late nights and extra stress. It simply requires the right processes and tools to be in place before close even begins.

A strong month-end close checklist is a great starting point, providing clarity on what needs to happen when. From there, the right systems help reduce manual work and ensure the tasks on that list happen at the right time, every time, and without adding friction. 

Closing the books faster is great. But the ultimate goal is to make the process predictable, accurate, and far less stressful every month.
