How Zerotouch automates GL code verification for accuracy, speed, and compliance

In most finance teams, the accounts payable process involves several steps: receiving invoices, checking their details, getting approvals, and posting them for payment. While these tasks are routine, they often slow down because many of them are still handled manually. One of the biggest pain points is GL code verification making sure every invoice is recorded under the right account. When done by hand, this step is time-consuming and prone to mistakes, which can lead to reporting errors and extra rework at month-end.

This is where Zerotouch invoice automation brings real change. Instead of relying on people to manually check and assign GL codes, the system automatically reads each invoice, validates the information, matches it with existing data, and applies the correct GL code based on set rules or learned patterns. It can then route invoices for approval and post them directly into the system, all with little to no human effort.

With ZeroTouch automation, finance teams no longer have to spend hours verifying or correcting GL codes. The process becomes faster, more accurate, and completely traceable. This not only improves financial accuracy but also frees up time for teams to focus on analysis and decision-making instead of data entry. In short, ZeroTouch turns what used to be a slow, error-prone process into a smooth, reliable workflow that keeps numbers clean and the business moving efficiently.

What is GL code verification in accounts payable?

GL code verification in accounts payable is the process of checking and confirming that each invoice is assigned the correct general ledger code, a unique accounting identifier used to classify expenses, such as office supplies, travel, or utilities, to ensure that all transactions are recorded accurately for financial reporting and compliance.

How GL code verification works in accounts payable

In every company’s finance system, each type of expense or income is linked to a specific GL code. These are unique accounting identifiers that help classify transactions for example, office supplies, travel expenses, software subscriptions, or utilities. Every time an invoice is processed, the accounts payable team assigns the correct GL code so that the cost is recorded in the right place in the books.

During invoice processing, AP staff usually check what the invoice is for, which department it belongs to, and what type of expense it represents. Based on that, they select the appropriate GL code before posting it into the accounting system. For instance, an invoice for printer paper would go under “Office Supplies,” while a hotel  

The main purpose of GL code verification is to make sure every expense is recorded accurately and consistently. This helps the finance team produce reliable reports, track spending across departments, and stay compliant with accounting standards and audit requirements. When GL codes are applied correctly, management can clearly see where money is being spent, make informed budget decisions, and maintain a transparent financial record.

However, because this process is often

How GL code verification works step-by-step

Step 1: Invoice received from vendor

The process starts with the receipt of an invoice from a vendor or supplier. Invoices serve as the official record of goods or services provided and form the basis for financial obligations. Proper logging and acknowledgment of the invoice are essential to maintain visibility, prevent delays, and track overdue payments. This initial step sets the foundation for all subsequent actions in the AP workflow.

Step 2: Extract key details

Once the invoice is received, the AP team captures critical information such as invoice amount, vendor details, department responsibility, and expense type. Accurate extraction is crucial because any missing or incorrect information at this stage can propagate errors throughout the accounting system. Capturing precise data ensures that GL code assignment and subsequent approvals are based on reliable inputs, reducing rework and inconsistencies.

Step 3: Assign the right GL code

With the extracted data, the AP team refers to the company’s chart of accounts to assign the appropriate GL code to each invoice. The GL code links the transaction to a specific category of expense or liability, allowing for structured and standardized financial recording. Proper assignment ensures that all financial statements, budget reports, and analytical insights reflect the true nature of business expenses. Misclassification at this stage can distort reporting, affect budget management, and undermine operational decision-making.

Step 4: Verify GL code accuracy

Verification is the critical checkpoint where the assigned GL code is reviewed for correctness. This step ensures alignment between the expense type, the responsible department, and the company’s financial structure. It serves as a control mechanism to prevent misclassification, duplicate entries, or misallocation of costs. Verification not only safeguards the integrity of financial data but also strengthens compliance with internal policies and regulatory standards.

Step 5: Post verified invoices

Once the GL code is verified, the invoice is posted into the ERP or accounting system. Posting finalizes the transaction in the financial records, making it available for reporting, budget tracking, and payment processing. Accurate posting ensures that all subsequent financial reports, audits, and analyses are based on verified and reliable data, supporting better strategic decisions and operational control.

Common challenges in manual GL code verification

1. Human errors in code selection

Manual assignment of GL codes relies heavily on the judgment and attention of AP staff. Even experienced personnel can make mistakes, especially when dealing with large volumes of invoices. Selecting the wrong GL code can lead to misclassified expenses, which not only distorts reports but also complicates audits and regulatory compliance. Repeated errors reduce confidence in financial data and can necessitate time-consuming corrections.

2. Time-consuming cross-checks

Invoices often need to be cross-verified against purchase orders, departmental budgets, and contracts. This requires communication across multiple teams or departments to confirm details. The manual back-and-forth slows down the entire AP process and can create bottlenecks. In organizations with high invoice volumes, this step can significantly delay approvals and posting, impacting cash flow and reporting timelines.

3. Lack of standardized GL mapping

In many organizations, there is no consistent method to map invoice types to GL codes. Different team members may interpret expense categories differently, leading to inconsistent coding. This lack of standardization complicates financial analysis, as similar expenses can appear under multiple accounts. It also increases the risk of discrepancies during audits, making transparency and traceability more difficult to maintain.

4. Misclassification leading to inaccurate financial reports

When invoices are misclassified due to human error or inconsistent practices, financial statements and departmental reports become unreliable. Misclassification can distort cost tracking, hide overspending, or misrepresent budgets. For management, this means decision-making is based on flawed data, potentially affecting strategic planning, resource allocation, and business performance evaluations.

5. Increased workload during month-end closing

Manual GL code verification becomes even more challenging during month-end or quarter-end closings when invoice volume spikes. The finance team faces pressure to complete verifications quickly to meet reporting deadlines. This surge in workload increases the likelihood of errors and often results in overtime, staff fatigue, and stress, further impacting accuracy and efficiency.

6. Reduced operational efficiency

Because manual verification is repetitive and labor-intensive, it consumes valuable staff time that could otherwise be used for analysis, forecasting, or strategic financial planning. The manual process slows down the entire accounts payable cycle, delaying payment processing and affecting vendor relationships.

7. Audit and compliance risks

Errors in GL code assignment or inconsistencies in classification can raise concerns during audits and make it difficult to demonstrate compliance with accounting standards. Regulatory authorities and internal auditors expect accurate, traceable records; manual processes increase the risk of discrepancies and potential penalties.

The impact of incorrect GL coding on businesses

1. Financial reporting inaccuracies

Incorrect GL coding directly affects the accuracy of financial statements. Expenses may be recorded under the wrong category, departmental costs can appear inflated or understated, and the organization’s overall financial position can be misrepresented.

These inaccuracies ripple through budgeting and forecasting processes. Management relies on accurate data to make strategic decisions such as resource allocation, cost reduction, and investment planning. Misreported expenses can lead to misguided decisions, missed opportunities, and even financial losses.

2. Delays in closing books

When invoices are misclassified, finance teams must spend additional time identifying and correcting errors. This slows down the month-end and quarter-end closing process, delaying the preparation of internal and external financial reports.

These delays can also impact operational efficiency. Departments may not receive timely insights into their actual spending, which affects budget monitoring, project planning, and cash flow management. In organizations with high invoice volumes, even a few misclassifications can create significant bottlenecks.

3. Compliance and audit risks

GL codes are a key control mechanism for maintaining financial transparency and regulatory compliance. Incorrect coding can trigger audit queries or findings, increasing the risk of penalties, fines, or reputational damage.

Auditors expect a clear trail of transactions that matches documented policies and regulatory requirements. Misclassifications complicate audits, requiring additional time and effort to explain discrepancies. This can lead to increased scrutiny, higher compliance costs, and potential legal or regulatory consequences.

4. Reduced visibility into expense categories and spending patterns

Accurate GL coding provides critical insights into where and how the organization is spending money. Incorrect codes obscure the true picture of expenses, making it difficult to analyze spending patterns, identify cost-saving opportunities, or detect anomalies.

Without reliable visibility, management cannot make informed decisions about resource allocation, departmental budgets, or operational efficiency. It also limits the ability to track trends over time, monitor project expenditures, and ensure that strategic initiatives are properly funded.

5. Operational inefficiencies and increased costs

Incorrect GL coding often leads to repeated manual corrections, increased workload, and longer processing times. AP teams may need to revisit invoices, communicate with multiple departments, and reconcile discrepancies, all of which consume valuable time and resources.

These inefficiencies can increase operational costs, reduce staff productivity, and divert attention from higher-value activities such as financial analysis, forecasting, and strategic planning. Over time, the cumulative impact of these inefficiencies can be significant.
