Overview
An accounts payable virtual assistant can take recurring invoice administration off a founder's or finance manager's desk without taking control of company payments. Keep the boundary plain: the assistant prepares the work, while an authorized employee approves it. The assistant can receive invoices, check required fields, match documents, enter approved data, maintain an exception queue, and prepare a payment batch.
This role fits a business with repeatable vendor
This role fits a business with repeatable vendor bills, a documented approval path, and an accounting system that supports separate permissions. It is a poor fit when no one owns vendor approval, staff routinely pay from email alone, or the books are too inconsistent to define a normal transaction. Fix those gaps before adding another person to the workflow.
Give vendors one monitored address or portal so
Give vendors one monitored address or portal so bills do not scatter across individual inboxes. The assistant logs the vendor, invoice number, invoice date, due date, amount, purchase order when one exists, requester, approver, and file location. That log is the daily work queue. It also exposes a missing approval before the due date passes.
Next
Next, check the invoice against the vendor record and the documents behind the purchase. A company that uses purchase orders may compare the purchase order, receipt, and invoice. A service business may compare the bill with a signed agreement, approved scope, or recurring-bill schedule. When the documents disagree, the assistant records the difference and sends it to the named reviewer.
Check for duplicates before entering a bill
Check for duplicates before entering a bill. Search the accounting system by vendor, invoice number, amount, and date. Small formatting changes matter. A vendor may remove a leading zero or resend the same bill from another email address. Put possible duplicates in the exception queue. The reviewer, not the assistant, decides whether to reject or process them.
Once the documents match
Once the documents match, the assistant can code the bill from a written chart-of-accounts guide and save it as a draft. New vendors, changed bank details, unusual amounts, missing tax forms, and transactions outside the guide need review. The reviewer owns the accounting decision. The assistant writes a short note stating what is missing and who needs to answer.
Payment preparation may include grouping approved bills
Payment preparation may include grouping approved bills by due date, checking discounts already stated in vendor terms, and producing a batch summary. A designated employee should retain final approval and payment release. Do not issue a shared bank password or an unrestricted administrator account. One person should not be able to create a vendor and then pay that vendor without another review.
File the evidence after payment
File the evidence after payment. Attach the approval and proof of payment, update the invoice status, and store the record where the business can retrieve it. IRS guidance says expense records should identify the payee, amount paid, proof of payment, date incurred, and the business purpose. It lists invoices, statements, receipts, and canceled checks or other electronic-payment evidence as examples.

The company still owns its records when
The company still owns its records when an assistant does the clerical work. IRS guidance on automated records says that using a third party for record services does not transfer the taxpayer's recordkeeping responsibility. It also calls for an audit trail linking retained records, the books, and the tax return. Source: https://www.irs.gov/businesses/automated-records
Give the assistant access for the assigned work
Give the assistant access for the assigned work only. Create an individual account, turn on multifactor authentication, limit it to the required company and modules, and exclude payment release when the platform permits it. CISA advises businesses to require MFA for staff who handle sensitive data. Its security guidance also recommends least-privilege access, which limits an account to the permissions its user needs.

Keep the exception queue short and consistent
Keep the exception queue short and consistent. Useful reasons include missing approval, an unmatched amount, a missing receipt, a possible duplicate, a new vendor, changed payment details, or a coding question. Give every item an owner and next action. Review old exceptions and repeat causes each week. If one vendor often omits purchase order numbers, correct the vendor instruction instead of repeating the same chase each month.
Judge the first 30 days with counts
Judge the first 30 days with counts the team can verify. Track invoices received, invoices entered without correction, possible duplicates caught before entry, overdue exceptions, bills awaiting approval, and files missing proof of payment. Review a sample of completed records against the source invoice and approval. Volume alone does not show good work when entries need cleanup or the evidence trail is incomplete.
Test candidates on the job they will do
Test candidates on the job they will do. Give them a sample invoice packet and ask what is missing, how they would write the escalation note, and which action needs approval. Look for careful reading, consistent naming, comfort with repetitive queues, and a willingness to stop when documents conflict. Speed does not make up for ignored controls.
Before handoff
Before handoff, document the intake address, naming rules, coding guide, approval matrix, payment calendar, exception owners, and access-removal process.
