A disbursement check voucher is an internal accounting document that authorizes and records a company’s payment before any money leaves the account. It isn’t a check, and it isn’t an invoice. It’s the company’s formal sign-off proving that someone reviewed the bill, confirmed the goods or services arrived, coded the expense to the right account, and secured the necessary approvals. The voucher ties the vendor’s invoice to the eventual payment and becomes the paper trail auditors follow when they want proof that every dollar went where it was supposed to.
What the Voucher Does
Every business pays bills. The voucher exists so no payment goes out on autopilot. Before a cent is released, it confirms three things: the company actually owes the money, the right people approved spending it, and the accounting system recorded it in the correct expense category.
In practice, the Accounts Payable department creates the voucher after verifying that a vendor’s invoice is legitimate. Preparing the voucher is the moment AP formally accepts responsibility for processing the payment. Until then, the invoice is just a request sitting in a queue. Once the voucher is complete and signed, it becomes the green light for the treasury or disbursement team to cut the check or send the electronic payment.
What Goes on the Voucher
A voucher is only as useful as the information on it. Missing or inaccurate fields create problems that ripple through financial statements, tax filings, and audits.
Vendor Identification
The voucher records the vendor’s legal name, address, taxpayer identification number, and the specific invoice number or numbers being paid. Getting this right matters for more than sending payment to the correct place. Starting in 2026, businesses must file a Form 1099-NEC for any vendor paid $2,000 or more during the calendar year for services, up from the previous $600 threshold.1Internal Revenue Service. Form 1099 NEC and Independent Contractors If the vendor’s taxpayer ID is wrong or missing, the company must withhold 24% of the payment and send it to the IRS as backup withholding.2Internal Revenue Service. Instructions for the Requester of Form W-9 Collecting a completed Form W-9 before the first payment avoids that problem, and the voucher is a natural checkpoint to confirm the W-9 is on file.
Payment Amount and Account Coding
The total payment amount must match the liability on the corresponding invoice exactly. Below that total, the voucher breaks the expense into General Ledger account codes that classify where the money is going, such as office supplies, consulting fees, or equipment maintenance. Coding matters more than it sounds. If a $50,000 consulting payment is coded to office supplies, the income statement and balance sheet will both be wrong, and those misclassifications can add up to material errors that trigger audit findings.
Authorization Signatures
The voucher includes a section for approval signatures, and that’s where the real internal control lives. A typical signature chain runs from the AP clerk who prepared the voucher, to a departmental reviewer who checks the math and coding, to a manager with spending authority for that dollar amount. For large disbursements, a company may require a final sign-off from the CFO or another executive. The bigger the check, the more eyes on it before it leaves the building.
How a Voucher Gets Approved
The voucher isn’t created until the company runs what accountants call a three-way match. This is the step that catches most problems before they become payments. AP takes the vendor’s invoice and compares it against two other documents: the original purchase order and the receiving report confirming the goods or services actually showed up.
The purchase order shows what was ordered, the quantities, and the agreed price. The receiving report confirms what was delivered. The invoice states what the vendor wants to be paid. If all three align within an acceptable tolerance, the AP clerk creates the voucher. If they don’t, the discrepancy gets investigated first. A vendor billing for 500 units when the receiving dock only logged 450 gets flagged here, not after the payment has already cleared.
Once the voucher is created with proper GL codes and payment terms, it moves to an independent reviewer who was not involved in preparing it. That reviewer checks the math, confirms the expense coding, and passes it up for management signatures. The separation between the person who prepares and the person who verifies is deliberate. No single employee should be able to create and approve a payment alone, because that’s exactly the gap where fraudulent payments slip through.
After every required signature is collected, the completed voucher package is attached to the check or electronic payment file. That package is what authorizes the treasury team to release the funds.
Voucher vs. Invoice vs. Check
These three documents get confused constantly, and they do completely different jobs.
The invoice comes from the vendor. It’s an external document that creates a legal obligation for the company to pay. When accounting receives a valid invoice, the company records a liability on the balance sheet under Accounts Payable.
The check, or electronic payment, is the instrument that moves money from the company’s bank account to the vendor. It executes the payment.
The voucher sits between those two, and it’s purely internal. The vendor never sees it. It doesn’t request payment, and it doesn’t make payment. It documents the company’s internal decision that the payment is justified, properly coded, and approved. The invoice says “you owe us,” the voucher says “we’ve verified that and approved the spend,” and the check says “here’s the money.”
This separation keeps the person who incurred the expense away from the person who authorized the payment and the person who actually sent the money. That division of responsibilities, known as segregation of duties, is one of the most effective controls against misuse of company funds.
When a Voucher Is Voided or a Check Isn’t Cashed
Sometimes a payment gets approved but needs to be stopped. Maybe the check was printed with the wrong amount, the vendor sent a corrected invoice, or a duplicate slipped through. When that happens, the voided voucher and its associated check still need to be documented, not thrown away.
The standard procedure is to mark the check as “VOID” in the accounting system, physically deface the paper check so it can’t be used, and keep it filed with other checks for the permanent record. Prenumbered checks make this easier because auditors can verify that every check number is accounted for, whether it was used or voided. For electronic payments, the same logic applies inside the ERP system: the voided transaction gets a clear status entry and a record of why it was reversed.
Duplicate payments deserve special attention because they’re one of the most common AP errors. Automated duplicate detection in the accounting system helps, as does a strict policy against processing invoices without a matching purchase order. Periodic spend audits catch duplicates and overpayments that slipped past the front-line controls, and reconciling vendor statements against the company’s records is another reliable way to spot missed credits or unexplained balances before they age into real losses.
Uncashed checks are their own problem. Every state has unclaimed property laws requiring businesses to report outstanding checks that remain uncashed beyond a specified dormancy period and eventually turn the funds over to the state.3U.S. Department of Labor. Introduction to Unclaimed Property Dormancy periods typically range from one to five years depending on the state, and businesses must attempt to contact the payee before reporting the funds. The voucher package provides the documentation needed to identify stale payments, confirm their original purpose, and demonstrate compliance with reporting deadlines.
Why the Paperwork Matters Later
The completed voucher package is the single most important source document for both internal and external auditors reviewing expense accounts. Each voucher proves that a specific payment was authorized by the right people, matched against supporting documents, and coded to the correct account. For public companies, weak voucher controls are exactly the kind of deficiency that can show up as a material weakness in the annual assessment of internal controls over financial reporting required by Section 404 of the Sarbanes-Oxley Act.4Office of the Law Revision Counsel. 15 U.S. Code 7262 – Management Assessment of Internal Controls
The voucher package also provides the substantiation the IRS expects if it audits the company’s expense deductions. How long those records need to stick around depends on the circumstances. The general rule is three years from the date the return was filed. That extends to six years if the company failed to report more than 25% of its gross income, and to seven years if the return involved a bad debt deduction or a claim for worthless securities.5Internal Revenue Service.
