How to Merge Receipts for an Expense Report

Most professionals handle receipts in at least four different formats: paper receipts, email PDF confirmations, app-generated PDFs (Uber, Lyft, hotel apps), and photos taken with a phone. Getting all of these into one coherent document is where the friction lives. Finance teams consistently report that the main reasons expense reports get kicked back are: 1. Missing receipts (attached to the claim but not in the document) 2. Unreadable receipts (blurry photos, too-dark scans) 3. Wrong format (finance portals often require a single PDF, not a zip of images) 4. No logical organization (receipts in random order, no summary) A single, well-organized merged PDF that includes every receipt in chronological order, with a cover summary page, solves all four problems simultaneously.

The foundation of a good expense report is complete, high-quality receipt capture. Before you can merge anything, you need everything collected.

1. 1Check your email for PDF receipts and confirmations — download them all to a dedicated expense folder
2. 2Download any app receipts: Uber/Lyft (trip history → download receipt), hotel apps, airline apps
3. 3For paper receipts, photograph each one clearly: lay flat on a contrasting surface, good lighting, capture all four corners
4. 4For photos, use your phone's document scanning feature (iOS Notes, Android Google Drive scan) for better quality than a regular photo
5. 5Name all files chronologically: YYYY-MM-DD-description.jpg (e.g., 2026-03-10-client-lunch.jpg)
6. 6Move all files to a single folder — separate from your general Downloads

Before merging, convert all image receipts (JPG, PNG) to PDF. This ensures a uniform format for the final merge.

1. 1Go to LazyPDF Image to PDF tool at lazy-pdf.com/en/image-to-pdf
2. 2Select all your receipt image files at once
3. 3Order them chronologically in the upload list
4. 4Convert — each image becomes a PDF page
5. 5Download the resulting PDF (this creates all image receipts as one document)
6. 6Split this into individual page PDFs if your expense system needs one receipt per file, or keep as one multi-receipt PDF for merging with other documents

With all receipts in PDF format, merge them with any accompanying documentation (expense claim form, mileage log, approval emails) into a single comprehensive report.

1. 1Create a simple cover page in Word or Google Docs: your name, department, trip/period dates, total amount claimed, and a list of included receipts with amounts
2. 2Export the cover page as PDF
3. 3Go to LazyPDF Merge tool at lazy-pdf.com/en/merge
4. 4Upload in order: cover page first, then expense claim form, then receipts chronologically
5. 5Review the order and drag to reorder if necessary
6. 6Click 'Merge PDFs' and download the complete expense report

Expense reports with many photo receipts can become large. Company portals, especially older ones, often have file size limits of 5–10MB. After merging, check the file size. If it's over 10MB, run it through LazyPDF's compress tool with medium compression. Receipt images are excellent candidates for compression — they contain simple content (printed text on white paper) that compresses extremely efficiently without any visible quality loss. A typical monthly expense report with 20–30 receipts compresses from 15–30MB down to 3–7MB with medium compression. The result is well within any portal's limits and fast to upload. **Submission tips:** - Keep the original uncompressed version in your records - Submit before month-end deadlines — late submissions often can't be processed in the current accounting period - Follow up if you don't see the expense in your next paycheck — sometimes submissions get lost in approval workflows - For recurring travel, create a template expense report cover page that you simply update each time

If you travel or entertain clients regularly, a few habits dramatically reduce the time expense reports take: **Same-day receipt processing**: Spend 2 minutes after each expense to photograph or save the receipt while the context is fresh. Processing 30 receipts one by one during a trip is much faster than reconstructing everything 3 weeks later. **Use a dedicated app**: Apps like Expensify, Rydoo, or SAP Concur automate much of this process — they capture receipts, categorize them, and generate expense reports automatically. However, they usually still need you to export a PDF for submission to your company's accounting system. **Keep a running log**: A simple note on your phone tracking each expense (date, vendor, amount, purpose) serves as a backup if receipts are lost. **Know your company's policy**: Understand the receipt threshold (many companies don't require receipts under $25), the expense categories, and the reimbursement deadline before your trip. Non-compliant submissions waste everyone's time.
