Before diving into automation, let's clarify what we mean by these accounting terms:

Recurring Journals: The Entries You Make Like Clockwork

These are the journal entries that happen with the same amounts on the same schedule, again and again:

  • Monthly depreciation entries
  • Amortization of prepaid expenses
  • Regular lease or rental payments
  • Standing allocations of overhead costs
  • Subscription and membership fees

I was shocked to discover that at one company I worked for, we were manually entering 47 recurring journals each month—most with identical amounts month after month. That's nearly 600 manual entries annually that could be automated.

Accruals: Matching Reality When Timing Doesn't Cooperate

Accruals involve recognizing expenses or revenues before the actual cash transactions occur:

  • Utility bills that arrive after month-end
  • Commissions earned but not yet paid
  • Interest accumulated on loans or investments
  • Revenue earned on percentage-of-completion projects
  • Vacation time accrued by employees

These entries often involve calculations and estimates, making them even more time-consuming and error-prone when done manually.

The Real Cost of Manual Month-End Processes

When I audit accounting departments, I find most teams dramatically underestimate the true cost of manual processes. It's not just about time—it's about risk, quality, and opportunity cost.

The Time Tax

At a 100-person software company where I consulted, I tracked how the accounting team spent their time during month-end:

  • 24 hours on recurring journal entries
  • 18 hours on accrual calculations
  • 16 hours finding and fixing errors
  • 10 hours on reviews and approvals

That's 68 hours—more than eight full workdays—spent on tasks that could be largely automated.

The Error Factor

Manual processes aren't just slow—they're unreliable. At a healthcare company I worked with, we tracked errors before and after automation:

Error TypeBefore AutomationAfter Automation
Incorrect amounts5–7 per month0–1 per month
Missed entries3–4 per month0 per month
Coding mistakes8–10 per month0–1 per month
Calculation errors6–8 per month0 per month

Each error took 30-90 minutes to track down and fix. More importantly, these errors sometimes led to inaccurate financial reporting and poor business decisions.

The Opportunity Cost

Perhaps the biggest hidden cost is what your accounting team could be doing instead. After automating at a manufacturing client, their accountants:

  • Developed better inventory valuation methods
  • Created cash flow forecasting models
  • Analyzed product line profitability
  • Partnered with operations on cost reduction

The value of these activities far exceeded the time saved through automation.

How to Automate Month-End Tasks: A Practical Guide

Having implemented automation at multiple companies, here's my step-by-step approach that works regardless of your accounting system:

Step 1: Map Your Current Process

Before changing anything, document your existing process:

  1. List every recurring journal and accrual
  2. Note the frequency, amounts, and calculation methods
  3. Track how long each entry takes
  4. Identify who performs and approves each entry
  5. Document how the information is gathered

A manufacturing controller I worked with discovered his team was making 78 separate recurring entries monthly—far more than anyone realized.

Step 2: Categorize Your Entries

Not all entries are equally automatable. Sort yours into these categories:

CategoryDescriptionExamplesAutomation Potential
FixedSame accounts, same amountsRent, straight-line depreciationHigh (100% automated)
Variable with formulaSame accounts, calculated amountsUtility accruals based on daysHigh (90%+ automated)
Variable with data inputRequires external dataRevenue based on production countsMedium (process automated, data input required)
Judgment-basedRequires significant analysisBonus accruals, bad debt reservesLow (calculations automated, judgment still needed)

A retail client found that 65% of their entries fell into the "Fixed" or "Variable with formula" categories, making them perfect automation candidates.

Step 3: Choose Your Automation Approach

Your options depend on your accounting system:

Option 1: Built-in Automation Features

Most modern accounting systems have built-in automation capabilities:

  • SAP: Recurring Entry Functionality
  • Oracle: AutoAccounting and Journal Formulas
  • NetSuite: Memorized Transactions
  • Sage Intacct: Recurring Journal Entries
  • QuickBooks: Memorized Transactions or Recurring Transactions

A nonprofit I advised used NetSuite's Memorized Transactions to automatically distribute $1.2M in monthly overhead costs across 14 departments and 36 grant funds—a process that previously took two full days.

Option 2: Spreadsheet Integration

For more complex calculations:

  1. Create template spreadsheets with formulas
  2. Link spreadsheets to source data where possible
  3. Use macros or scripts to generate journal import files
  4. Schedule automatic imports to your accounting system

A manufacturing client used Excel macros to create a sophisticated work-in-process accrual based on production data, saving 6 hours monthly and improving accuracy.

Option 3: Specialized Automation Software

For advanced needs, consider dedicated financial close automation tools:

  • BlackLine
  • FloQast
  • Trintech
  • Redwood
  • Workiva

These platforms typically offer workflow automation, documentation, and controls beyond simple journal automation.

A global retailer I worked with implemented BlackLine and reduced their close process from 12 days to 5, while improving controls and documentation.

Step 4: Design and Test Your Automation

Before full implementation:

  1. Build your automated process for each entry type
  2. Run it in parallel with manual processes for 1-2 months
  3. Compare results and refine the automation
  4. Document the new process thoroughly
  5. Create exception handling procedures

A healthcare client discovered during testing that their automated depreciation calculations didn't properly handle mid-month asset acquisitions. They adjusted their automation rules before going live.

Step 5: Implement Controls and Reviews

Automation doesn't mean abandoning oversight:

  1. Build analytical reviews to flag unusual results
  2. Maintain approval workflows for automated entries
  3. Schedule periodic audits of automation rules
  4. Document all automations for your auditors
  5. Create clear change management procedures

An energy company implemented monthly variance reports that automatically flagged any automated entry that deviated from historical patterns by more than 10%, creating a smart review system.

Real-World Examples: How Companies Cut Days Off Their Close

Here are three specific examples of how my clients transformed their month-end processes:

Case Study: Software Company (250 employees)

Before automation:

  • 8-day close process
  • 42 recurring entries entered manually
  • Frequent errors in commission accruals
  • Two accountants dedicated to month-end for the full period

After automation:

  • 4-day close process
  • 38 entries fully automated; 4 partially automated
  • Rules-based commission accrual system
  • One accountant handling month-end part-time

How they did it: They used NetSuite's native automation features for standard entries and built a custom commission calculation tool that integrated with their CRM data.

Case Study: Manufacturing Business (500 employees)

Before automation:

  • 15-day close process
  • Complex cost allocations across 12 departments
  • Frequent production-based accrual errors
  • Constant conflicts between accounting and operations

After automation:

  • 7-day close process
  • All allocations automated with approval workflows
  • 99.2% accuracy rate on production accruals
  • Better relationship with operations teams

How they did it: They implemented specialization, with dedicated staff managing specific automated processes and developing expertise in those areas. They also created automated data feeds from production systems.

Case Study: Professional Services Firm (120 employees)

Before automation:

  • 10-day close process
  • Project-based revenue recognition challenges
  • Inconsistent accrual methodologies
  • Excessive partner review time

After automation:

  • 5-day close process
  • Standardized revenue recognition rules
  • Consistent, documented accrual methodologies
  • 70% reduction in partner review time

How they did it: They built a custom revenue recognition module in their PSA (Professional Services Automation) system that calculated completion percentages, revenue earned, and created automated journal entries.

Common Pitfalls and How to Avoid Them

Having helped dozens of companies automate, I've seen these common mistakes:

1. Automating Broken Processes

The problem: Companies often automate existing processes without examining whether those processes make sense.

Solution: Before automating, ask: "Is this the right process in the first place?" Often, you'll find opportunities to simplify or eliminate steps entirely.

A retail client discovered they were creating accruals for 17 different expense categories that, combined, represented less than 0.5% of their total expenses. They established a materiality threshold and eliminated these immaterial accruals entirely.

2. Inadequate Testing

The problem: Rushing to implement without thorough testing across different scenarios.

Solution: Test your automation with:

  • Normal month-ends
  • Quarter and year-ends
  • Unusual transactions or timing
  • System upgrades or changes

A financial services firm failed to test their automation with quarterly tax accruals, leading to significant errors when these additional entries were needed.

3. Lack of Documentation

The problem: The automation works, but nobody understands how or why.

Solution: Create detailed documentation including:

  • Business rules behind each automation
  • Technical details of implementation
  • Testing procedures and results
  • Exception handling processes
  • Change management protocols

A healthcare client faced serious issues when their controller left and nobody understood the automation rules they had established. Proper documentation would have prevented months of confusion.

Beyond the Basics: Next-Level Accounting Automation

Once you've mastered recurring journals and accruals, consider these advanced automation opportunities:

Predictive Accruals

Use historical data patterns to create more accurate accruals:

  • Utility costs based on weather patterns and historical usage
  • Sales returns reserves based on historical return rates by product
  • Bonus accruals using year-to-date performance versus targets

A retail client built predictive models for their sales returns that analyzed return rates by product category, season, and sales channel, increasing accrual accuracy by 22%.

Cross-System Integration

Connect your accounting system with other business systems:

  • HRIS systems for payroll and benefits accruals
  • CRM data for commission calculations
  • Utility vendor portals for automatic bill import
  • Inventory systems for COGS calculations

A technology company eliminated 40+ hours of manual work by integrating their HRIS data directly into their accounting system for automatic payroll accruals.

Continuous Accounting

Move beyond month-end to a continuous close approach:

  • Process recurring entries weekly rather than monthly
  • Update accruals as new information becomes available
  • Implement rolling forecasts that update automatically
  • Create daily flash reports for key metrics

A manufacturing client now updates their production-based accruals daily, giving management much more timely information for decision-making.

Final Thoughts: The Human Side of Automation

After implementing accounting automation at dozens of companies, I've found that the technology is often the easy part. The real challenges—and opportunities—involve people:

Addressing Team Concerns

Accounting staff often worry that automation threatens their jobs. In reality, I've rarely seen automation reduce accounting headcount. Instead, it:

  • Eliminates tedious, repetitive work
  • Creates opportunities to add more value
  • Allows focus on analysis rather than data entry
  • Reduces stress and improves job satisfaction

A controller I worked with told her team: "We're not automating to reduce staff. We're automating so you can use your brains instead of just your fingers."

Evolving Your Team's Skills

As automation takes over routine tasks, help your team develop new skills:

  • Data analysis and visualization
  • Process improvement
  • Business partnership
  • Systems expertise
  • Advanced Excel or data tools

At a distribution company, the accounting team now spends 40% of their time on business analysis and process improvement versus less than 10% before automation.

The New Role of Accounting

Perhaps most exciting is how automation transforms accounting's role from financial recording to business partnership. When your team isn't drowning in manual entries, they can:

  • Provide insights that drive business decisions
  • Identify cost-saving opportunities
  • Develop more sophisticated forecasting models
  • Participate in strategic planning
  • Become true business advisors

And that's the real power of automation—not just saving time, but changing what's possible for your accounting function.
