GL Reconciliation: A Modern Guide for Finance Teams

GL reconciliation is one of the most critical—and most time‑consuming—parts of the close. When it's manual, it creates bottlenecks, hidden risk, and constant fire drills at month‑end. Modern GL reconciliation software changes that by automating transaction‑level matching, maintaining a "shadow ledger," and giving controllers real‑time visibility into what's reconciled and what's not.

This page explains how GL reconciliation automation works, the types of reconciliations it supports, and how it fits into your finance stack.

The Hidden Cost of Manual GL Reconciliation

Most teams underestimate how much manual GL reconciliation is really costing them—in time, risk, and missed opportunities.

Time and Capacity Drain

For many accounting teams:

• GL reconciliation consumes 25–40% of total close time
• Senior accountants spend 2–4 days per month exporting data to Excel, manually matching transactions, and chasing down differences
• Controllers and managers lose hours in review because support is fragmented across spreadsheets, email threads, and shared drives

In practice, this looks like:

• Pulling trial balances and transaction detail from the ERP
• Downloading bank statements and payment processor reports
• Cleaning and reformatting CSVs so formulas don't break
• Manually ticking and tying thousands of lines to get to a zero variance

Beyond the month‑end crunch, manual GL reconciliation also bleeds into:

• Ad hoc investigations: Tracing unexplained variances back through months of spreadsheets
• Rework: Fixing miscodings, duplicate entries, and reconciliation errors discovered late in the process
• Context switching: Bouncing between ERP reports, bank portals, and CSV exports

This isn't just an efficiency problem—it's a structural constraint on how fast you can close and how much analysis your team can realistically do.

Error Rates and Downstream Impact

Manual processes are inherently error‑prone:

• Copy‑paste errors when moving data between systems and spreadsheets
• Mis‑keyed amounts or dates
• Incorrect mapping between GL accounts and source data
• Broken or overridden spreadsheet formulas
• Missed or partial matches when volumes are high

Even a 1–2% error rate in reconciled populations can:

• Distort management reporting and KPIs
• Lead to misstated balances that roll forward for multiple periods
• Require painful restatements or post‑close adjustments
• Undermine trust in the numbers from FP&A and leadership

Because most manual reconciliations are point‑in‑time (e.g., at month‑end), errors can sit undetected for weeks or months. By the time they surface—often during audit or year‑end review—the effort to unwind them is disproportionately high.

Audit and Control Risk

Manual GL reconciliation also increases risk:

• Weak audit trails: Support is scattered across personal drives, email, and spreadsheets with no clear version history
• Inconsistent procedures: Each accountant has their own template and approach
• Limited segregation of duties: The same person may prepare and effectively self‑review reconciliations
• Reactive controls: Issues are found after the fact, not prevented

During audits, this shows up as:

• Longer PBC (prepared‑by‑client) lists and more back‑and‑forth
• Extra samples pulled because controls are deemed manual or informal
• Findings around reconciliation timeliness and documentation quality

GL reconciliation software addresses these problems by standardizing processes, centralizing support, and providing system‑level controls and logs.

Types of GL Reconciliation

GL reconciliation is not a single process; it's a set of related reconciliations, each with its own data sources, matching rules, and risks. Modern GL reconciliation software should support all of these.

Bank Reconciliation

Bank reconciliation ensures that cash balances in the GL match external bank statements.

Key activities:

• Importing bank statements from multiple banks and accounts
• Matching deposits and withdrawals to customer payments, vendor payments, payroll runs, and treasury activity (FX, investments, debt)
• Identifying outstanding checks and deposits in transit, bank fees, interest, FX differences, and fraudulent or unexpected transactions

Automation can:

• Perform transaction‑level matching using amount, date, reference, and counterparty
• Auto‑post bank fees and interest to the correct GL accounts
• Surface only true exceptions for review

Sub‑Ledger to GL Reconciliation

Sub‑ledger reconciliations verify that detailed subsidiary ledgers tie to control accounts in the GL (e.g., AR, AP, inventory).

Examples:

• Accounts receivable sub‑ledger → AR control account
• Accounts payable sub‑ledger → AP control account
• Fixed assets module → Fixed asset and accumulated depreciation accounts
• Inventory systems → Inventory and COGS accounts

Key checks:

• Ending balances match between sub‑ledger and GL
• All sub‑ledger activity has been posted to the GL
• No manual journal entries bypassed the sub‑ledger

Automation can:

• Continuously compare sub‑ledger and GL balances
• Flag differences by period, entity, and account
• Trace differences back to missing or duplicated journal entries

Payment Processor and Gateway Reconciliation

For digital‑native and high‑volume businesses, payment processor reconciliation is often the hardest to manage. It involves matching:

• Individual customer transactions in billing or order systems
• To processor reports (Stripe, Adyen, PayPal, etc.)
• To net payouts hitting bank accounts
• To revenue and fee entries in the GL

Complications include:

• Fees, refunds, chargebacks, and FX adjustments netted against payouts
• Batch settlements spanning multiple days or currencies
• Reserve holds and delayed releases

Specialized GL reconciliation software can:

• Ingest detailed processor reports and settlement files
• Reconcile gross → net → bank → GL
• Auto‑calculate and post fee, FX, and chargeback entries

See Payment Reconciliation Software for more detail.

Intercompany Reconciliation

Intercompany reconciliations ensure that transactions between legal entities eliminate correctly on consolidation.

Common challenges:

• Different ERPs or instances per entity
• Mismatched currencies, FX rates, and posting dates
• Asymmetric booking (one side recorded, the other missing)
• Manual top‑side entries

GL reconciliation software can:

• Pair intercompany transactions using reference IDs, counterparties, and amounts
• Identify one‑sided or mismatched entries
• Support multi‑currency matching and FX difference analysis
• Provide dashboards by counterparty entity and aging of unreconciled balances

Suspense and Clearing Account Reconciliation

Suspense, clearing, and "undistributed" accounts are often used as temporary holding accounts when data is incomplete or processes are manual.

Examples:

• Cash clearing accounts
• Payroll clearing
• Unapplied cash / unapplied credits
• Card settlement clearing

Risks:

• Balances that should net to zero accumulate over time
• Aged items hide process issues (e.g., failed integrations, unmatched payments)
• Suspense accounts become de facto permanent storage for unexplained items

Automation helps by:

• Tracking every entry into and out of suspense accounts
• Aging items and highlighting those that remain unresolved beyond defined thresholds
• Suggesting likely matches based on historical patterns and metadata

Prepaid and Accrued Expenses Reconciliation

Prepaid and accrued expense accounts require schedules and rollforwards to ensure proper period allocation.

Examples:

• Prepaid insurance, software, and rent
• Accrued payroll, bonuses, and benefits
• Accrued vendor expenses and professional fees

GL reconciliation software can:

• Maintain amortization and accrual schedules
• Auto‑post monthly amortization and reversal entries
• Reconcile schedule balances to GL accounts
• Flag schedule/GL differences by period and entity

Other Reconciliation Types

Additional reconciliations that benefit from automation include:

• Tax accounts (VAT/GST, sales/use tax, income tax payable/receivable)
• Revenue recognition balances (deferred revenue vs. billing systems)
• Loan and debt accounts (principal, interest, fees)
• Payroll liabilities (withholding, employer taxes, benefits)

A flexible GL reconciliation platform should allow you to configure rules and workflows for any account that requires regular reconciliation.

Common Pitfalls in GL Reconciliation

Even mature teams run into recurring issues when reconciliations are manual or spread across disconnected tools.

Growing Suspense and Clearing Balances

Symptoms:

• Suspense accounts that never clear to zero
• Aged items that span multiple quarters or years
• Recurring "plug" entries to force reconciliations to tie

Root causes:

• Incomplete or failed integrations
• Lack of ownership for specific accounts
• No systematic aging and follow‑up process

GL reconciliation software enforces ownership, aging, and workflows so items can't sit indefinitely without explanation.

Timing Differences and Cut‑off Issues

Timing differences are normal but can obscure real problems when not clearly tracked.

Examples:

• Deposits in transit and outstanding checks
• Revenue or expenses recorded in the wrong period
• Intercompany transactions booked in different periods across entities

Without a system:

• Timing differences are tracked in ad hoc spreadsheets
• Explanations are not consistently documented
• Items that start as timing differences can become permanent reconciling items

Automation helps by:

• Classifying reconciling items as timing vs. permanent
• Tracking expected resolution dates
• Escalating items that don't clear in the next period

Data Latency and Stale Reconciliations

In many organizations, reconciliations are based on static exports:

• Data pulled at the end of the month
• Reconciliations completed days or weeks later
• New activity after export is not captured

This creates blind spots:

• Mid‑month issues go undetected
• "Reconciled" balances are already outdated by the time they're reviewed
• High‑risk accounts are only reviewed once per month or quarter

Modern GL reconciliation software connects directly to your ERP and source systems to keep reconciliations in sync with live data.

Lack of Standardized Audit Trails

Common problems:

• Multiple versions of the same reconciliation file
• No consistent naming or folder structure
• Approvals via email or chat with no link to the underlying data
• Difficulty proving who prepared, reviewed, and approved what, and when

A GL reconciliation platform centralizes:

• Supporting documentation
• Preparations and adjustments
• Approvals and sign‑offs
• System logs of all changes

This dramatically simplifies audits and internal control reviews.

How Modern GL Reconciliation Software Works

Under the hood, modern GL reconciliation software does much more than replace spreadsheets. It builds a structured, transaction‑level view of your financial data and keeps it continuously reconciled.

Transaction‑Level Matching Engine

At the core is a matching engine that:

• Ingests transactions from your ERP general ledger, bank and card statements, sub‑ledgers and operational systems
• Normalizes and enriches data (e.g., dates, currencies, references)
• Applies configurable rules to match:
  • One‑to‑one (single GL entry ↔ single bank line)
  • One‑to‑many (single deposit ↔ multiple customer payments)
  • Many‑to‑many (batched settlements, complex clearing)

Matching logic typically uses:

• Amounts and currencies
• Transaction dates and posting dates
• Descriptions, memos, and reference IDs
• Counterparty information (customer, vendor, bank account)

Unmatched or partially matched items are surfaced as exceptions for review.

The Shadow Ledger Concept

A powerful pattern in GL reconciliation software is the shadow ledger:

• The system maintains its own ledger‑like view of source system activity (e.g., bank, gateway, sub‑ledger) and expected GL postings based on configured rules
• It then compares what should have hit the GL (based on source data and rules) with what actually hit the GL (based on ERP data)

This enables:

• Detection of missing entries that never reached the GL
• Identification of unexpected entries that have no supporting source transaction
• Clear traceability from GL balances back to underlying business events

Think of it as a continuously reconciled mirror of your GL, driven by actual transaction flows.

Continuous Reconciliation

Instead of reconciling once per month, modern systems reconcile continuously:

• New data is pulled from ERPs, banks, and other systems on a schedule (or via webhooks)
• Matching rules are applied automatically in near real‑time
• Exceptions are updated as new transactions arrive

Benefits:

• Issues are caught and resolved during the month, not just at close
• Month‑end becomes a final review, not a discovery exercise
• High‑risk accounts can be monitored daily

Integration with Your Finance Stack

GL reconciliation software only works if it fits cleanly into your existing systems.

ERP and General Ledger Connections

Robust GL reconciliation software should integrate with major ERPs and GLs, including:

• NetSuite
• Sage Intacct and Sage 50/200/300
• Oracle (E‑Business Suite, Fusion/Cloud)
• SAP (ECC, S/4HANA)
• Microsoft Dynamics (D365, Business Central, GP)
• QuickBooks and Xero for smaller entities

Key capabilities:

• Read access to journal entries and account balances, sub‑ledger detail where available, and entity, segment, and dimension structures
• Write‑back (optional) for suggested or approved journal entries, adjustments and reclassifications, and reconciliation status or tags

Bank Feeds and Financial Institutions

For bank and cash‑related reconciliations, the software should support:

• Direct connections or aggregators for major global banks, regional and local banks, and credit card providers
• Automated statement retrieval with daily or intra‑day pulls
• Support for multiple formats (BAI2, MT940, CSV, etc.)

This eliminates manual downloads and ensures your cash reconciliations stay current.

Payment Processors and Revenue Systems

Payment and revenue reconciliations often span multiple systems:

• Payment gateways and processors: Stripe, Adyen, PayPal, Braintree, Checkout.com, etc.
• Card networks and merchant acquirers
• Billing and subscription systems: Zuora, Chargebee, Recurly, in‑house billing platforms
• eCommerce platforms and marketplaces

GL reconciliation software can:

• Ingest settlement reports, fee structures, and payout schedules
• Reconcile gross transactions → processor reports → bank deposits → GL entries
• Reconcile fees and chargebacks → GL expense and contra‑revenue accounts

See Payment Reconciliation Software for more detail.

Benefits of Automation

Moving from manual processes to GL reconciliation software delivers tangible benefits across the close.

Faster, More Predictable Close

Automation reduces the time required to:

• Prepare reconciliations (data extraction and formatting)
• Match transactions and identify exceptions
• Investigate and resolve differences

Teams typically see:

• Shorter close cycles (often by 1–3 days)
• Less end‑of‑month overtime and weekend work
• More predictable timelines for FP&A and reporting

Real‑Time Visibility into Reconciliation Status

Instead of asking "Are we done yet?" you get:

• Dashboards showing reconciliation status by entity, account, and period
• Aged unreconciled items and high‑risk or high‑volume accounts
• Drill‑downs from GL balances to transaction‑level detail
• Clear ownership and workflow for each reconciliation

Controllers and accounting managers can see at a glance which accounts are reconciled, which are in progress, and where bottlenecks and recurring issues are.

Audit Readiness and Stronger Controls

GL reconciliation software improves your control environment by:

• Standardizing reconciliation formats and procedures
• Enforcing preparer/reviewer workflows
• Maintaining immutable audit trails: who did what, when, and why; what changed between versions; how exceptions were resolved

For audits, this translates into:

• Faster PBC turnaround
• Fewer follow‑up questions
• Reduced control findings related to reconciliations

Reduced Manual Effort and Rework

By automating the repetitive parts of reconciliation, you can:

• Eliminate manual CSV exports and copy‑paste work
• Minimize one‑off Excel logic and fragile formulas
• Reduce duplicate effort across entities and periods

Your team's time can shift from mechanical matching and data wrangling to analyzing trends, improving upstream processes, and addressing root causes of exceptions.
