Objective. Students will attach source documents to the correct QuickBooks transactions and use QuickBooks search and report tools to retrieve records on demand, supporting the organized recordkeeping tested in the QuickBooks Certified User exam.
This lesson, its worked examples and its practice questions has not yet been verified by a credentialed professional in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Every transaction in your books should be supported by a source document—an invoice, a receipt, a bank statement, or a signed agreement. Attaching that document directly to the matching QuickBooks transaction closes the loop between the paper (or digital) record and the accounting entry. During an audit, a tax review, or an employer inspection, you can pull up the transaction and see the proof immediately, without digging through file cabinets or separate folders. The QuickBooks Certified User exam tests whether you understand how document management connects to accurate bookkeeping, so mastering attachments is both a practical skill and an exam requirement.
QuickBooks Online (QBO) lets you attach files—PDFs, images, and other common formats—directly to most transaction types: bills, invoices, sales receipts, checks, deposits, journal entries, and bank-reconciliation records. Attachments are stored in the cloud alongside the transaction, so anyone with authorized access to the company file can view them.
To attach a file to a transaction:
1. Open the transaction (for example, a vendor bill).
2. Locate the Attachments area at the bottom of the transaction form.
3. Click Attach files (or drag and drop) and select the PDF or image from your device.
4. Save the transaction. A small paperclip icon will now appear on that transaction in lists and reports, confirming a document is linked.
For a bank reconciliation, open the completed reconciliation record through Reports > Reconciliation Reports, then use the attachment option on that record. Always match the document to the exact period—attaching a January bank statement to a February reconciliation is an error that could mislead anyone reviewing the file.
The Attachments page (found under the gear icon or the Banking menu, depending on your QBO version) acts as a central library of every file you have attached across all transactions. From there you can search by file name, transaction type, or date. This is particularly useful when a vendor calls to ask whether you received their invoice—you can confirm the attachment without re-opening every bill.
Keep file sizes reasonable and use descriptive file names before uploading (for example, `2024-03-VendorName-INV1045.pdf`). Uploading a file called `scan001.pdf` makes future retrieval much harder.
QBO's Search bar (the magnifying glass icon) lets you search by amount, name, transaction number, or memo. For quick lookups this is the fastest tool. However, when you need to know who changed what and when, you need the Audit Log.
The Audit Log (gear icon > Audit Log) records every action taken in the company file: who created, edited, or deleted a transaction, what the original values were, and what they were changed to. This is essential for identifying errors—such as a check that was posted to the wrong expense account—and for demonstrating internal controls during reviews.
To use the Audit Log effectively:
Always retrieve the full history for any transaction you are investigating, not just the most recent entry. A transaction may have been edited multiple times.
Reports such as Transaction List by Date or Vendor Detail let you produce a dated snapshot of activity for any period. To filter a report, click Customize, set your date range, and apply any additional filters (vendor name, account, etc.). Review the results on screen before exporting.
To export: click Export (the icon that looks like a document with an arrow) and choose Export to PDF or Export to Excel. Rename the file immediately using your class naming convention before saving it to the correct folder in your class folder structure. Filing a correctly named, correctly dated report in the wrong folder—or saving it with a generic name—defeats the purpose of an organized records system.
Source documents may contain sensitive information: vendor banking details, customer credit card data, or employee compensation records. Apply the principle of least privilege—only users who need access to specific transaction types should have it. In QBO, the primary admin sets user roles and permissions. Never share your login credentials with another person; each user should have their own account so that the Audit Log accurately reflects who performed each action. When working on a shared or lab computer, log out of QBO completely at the end of every session to prevent unauthorized access to the practice company.
The QuickBooks Certified User exam includes objectives related to locating transactions, using search features, and understanding how QuickBooks stores and tracks data. The AIPB Certified Bookkeeper credential emphasizes accurate, verifiable recordkeeping and internal controls—both of which depend on the document-management habits you are building here. Strong attachment and retrieval habits also support the Microsoft Office Specialist skills you use when you export reports to Excel for further analysis.
Answer each question, then check it. Nothing is recorded; this is your own practice.
