Why Month-End Closes Take Too Long (And How to Fix It Fast)

Written by Nova Advisory | Mon, Jun 2, 2025

For too many finance teams, the month-end close is a recurring nightmare: spreadsheets sprawled across desktops, manual reconciliations bogging down progress, and outdated numbers stalling executive decisions. Sound familiar?

You’re not alone. According to PwC’s 2023 Finance Benchmarking Report, the average finance team still takes 6.4 business days to close the books—and for many mid-market and high-growth organizations, it’s much longer.

In this article, we’ll explore:

  • Why the month-end close drags on

  • The strategic cost of delay

  • How platforms like OneStream can help finance teams close faster—with less chaos and more confidence

Why Does Closing the Books Still Take So Long?

As Nova Advisory’s CPM Customer Success podcast (Episode 48) outlines, slow financial closes are often the product of three systemic issues:

1. Disconnected Systems

Finance data lives across ERPs, CRMs, HR systems, and spreadsheets. Without integration, teams waste hours reconciling discrepancies.

2. Manual Reconciliations

Matching journal entries and handling intercompany eliminations by hand creates bottlenecks, errors, and audit headaches.

3. Overreliance on Spreadsheets

Spreadsheets remain a default tool for many teams, but they’re fragile, hard to audit, and riddled with human error. A study from Ventana Research found that 88% of spreadsheets contain errors, which directly impacts financial integrity.

“If your entire close process depends on fragile, error-prone spreadsheets, it’s a disaster waiting to happen.” — Andy Smetana, Host, CPM Customer Success

Why a Faster Close Isn’t Just Operational—It’s Strategic

A delayed close doesn’t just frustrate your team. It impacts decision-making and slows down the business.

Faster closes enable real-time insights

If leadership is making decisions on data that’s two weeks old, they’re not making decisions based on reality. A fast close gives you a competitive edge through timely, relevant data.

It fuels better forecasting

Late actuals mean outdated forecasts. An accelerated close delivers fresher data into planning models, improving forecast accuracy and agility.

It builds agility across the business

In a volatile market, the companies that adapt quickly are the ones that win. And agility starts with visibility.

Platforms like OneStream are built specifically to address these bottlenecks—helping finance leaders shift from firefighting to forward-thinking.

Next Steps: How to Accelerate Your Close

If you’re stuck in month-end chaos, here’s what to evaluate:

  • How long does your close currently take?

  • Where are the bottlenecks—data, people, tools, or processes?

  • What’s still manual that could be automated?

  • Are your insights timely enough to drive proactive decisions?
