Merge a Purchase Order PDF with Its Delivery Note for a Logistics Manager Reconciling Inventory on a Mac

To merge a purchase order PDF with its corresponding delivery note on a Mac, you can use a browser-based PDF merger that processes files locally—no software installation or account creation required—so you can produce a single, combined PDF ready for inventory reconciliation.

What You Will Need

• A Mac running macOS Catalina (10.15) or later, with Safari, Chrome, or Firefox installed
• The purchase order saved as a PDF file on your Mac
• The delivery note saved as a PDF file on your Mac
• A stable internet connection (only to load the web-based tool; your files stay on your device)
• Optional: a PDF reader like Preview (built into macOS) to verify the final output

Step-by-Step Instructions

Step 1. Open a browser-based PDF merger that runs locally

• Open Safari, Chrome, or Firefox on your Mac.

• Navigate to a browser-based PDF merging tool that explicitly states it processes files locally. One option is OctopusPDF, which runs entirely in the browser tab with no uploads. For a neutral alternative, you can also use Smallpdf or ILovePDF—both offer browser-based merging, though their privacy policies differ regarding server processing.

• Confirm the tool states "no upload" or "processed locally in your browser" before proceeding. This ensures your purchase order and delivery note never leave your device.

Step 2. Locate your purchase order and delivery note PDFs in Finder

• Open a new Finder window by clicking the Finder icon in your Dock.

• Navigate to the folder where you saved the purchase order PDF (for example, ~/Documents/Orders/PO-2024-1042.pdf).

• Repeat the same navigation to confirm the delivery note PDF is in the same or a nearby folder (for example, ~/Documents/Orders/DN-2024-0877.pdf).

• Keep both file windows open or note their exact paths—you will need to drag these files into the browser in the next step.

Step 3. Drag the purchase order PDF into the merge tool

• In the merge tool's interface, locate the drop zone labeled "Drop PDFs here" or "Choose files."

• Click and hold the purchase order PDF file in Finder, then drag it into the drop zone in your browser.

• Release the mouse button to drop the file.

• After dropping, you should see the file name appear in a list within the tool. If the file does not appear, click "Choose files" and select it manually from the dialog box.

Step 4. Drag the delivery note PDF into the merge tool

• Repeat the drag-and-drop process for the delivery note PDF.

• Drag the delivery note file into the same drop zone, releasing it below or after the purchase order in the list.

• The order of the files in the list determines the order in the merged output. Because you want the final document to read as "purchase order followed by delivery note," ensure the purchase order appears first in the list.

• Most merge tools allow you to reorder files by dragging items up or down in the list. If your delivery note appears above the purchase order, drag it down so the purchase order remains at the top.

Step 5. Rearrange the files if the order is incorrect

• Look for a drag handle (often represented by horizontal lines or a six-dot icon) on each file row.

• Click and hold the drag handle for the delivery note, then drag it to the position below the purchase order.

• Release to drop it into place.

• The order matters for your reconciliation workflow. When a logistics manager reviews the merged PDF, the purchase order on the first pages establishes the expected quantities, and the delivery note on the following pages documents what physically arrived. This ordering supports an efficient side-by-side comparison.

Step 6. Adjust merge settings (if applicable)

• Check whether the tool offers options such as "Merge into a single PDF" or "Combine files." For this task, you want a simple sequential merge—not a side-by-side or booklet layout.

• If the tool offers page range selection (e.g., "Merge specific pages"), leave it at the default "All pages" setting unless you have a specific reason to exclude pages.

• For this workflow, you are merging complete documents. If the tool offers advanced options like bookmark insertion or metadata preservation, leave them at their default values.

Step 7. Click the "Merge" button to combine the files

• Locate the primary action button, typically labeled "Merge," "Combine," or "Merge PDF."

• Click the button to start the merging process.

• The tool processes the files in your browser locally—no data is uploaded to a server. Depending on the file sizes, the merge may take a few seconds.

• Do not close the browser tab or switch to another app while the merge is processing.

Step 8. Download the merged PDF

• After the merge completes, the tool will display a download button, typically labeled "Download" or "Download merged PDF."

• Click the download button.

• Your browser will save the file to your default Downloads folder (e.g., ~/Downloads/).

• The file will have a name generated by the tool, often combining the original file names (e.g., PO-2024-1042-DN-2024-0877-merged.pdf). Rename it to something meaningful for your inventory records, such as PO-1042-DN-0877-Reconciliation.pdf.

Step 9. Open the merged PDF in Preview to verify page order

• Locate the downloaded file in Finder.

• Double-click the file to open it in Preview, the default PDF viewer on macOS.

• Scroll through the pages to confirm the purchase order appears first, followed by the delivery note.

• Verify that no pages are missing and that the page count matches the sum of the two source PDFs. For example, if the purchase order has 3 pages and the delivery note has 2 pages, the merged PDF should have 5 pages.

Common Mistakes / Troubleshooting

How to Verify Success

• The merged PDF opens in Preview without errors
• The first pages display the purchase order, with the PO number and line items legible
• The following pages display the delivery note, with the delivery reference and received quantities legible
• The total page count equals the sum of the two source PDFs
• No watermark or promotional text appears on any page
• All text is selectable (use Cmd+A then Cmd+C in Preview and paste to confirm text extraction) — this confirms the merge preserved the text layer
• You can search for a keyword like the PO number or delivery note reference within the merged PDF using Cmd+F in Preview

FAQ

Q1. Can I merge PDFs on my Mac without installing additional software?

Yes. Your Mac includes Preview, which can combine PDFs natively, but the workflow is less intuitive: you open both PDFs in Preview, then drag thumbnails from one document's sidebar to the other. A faster approach is to use a browser-based merger that processes files locally in the browser tab with no uploads, or general alternatives like smallpdf.com and ilovepdf.com—though those typically upload your files to their servers.

Q2. Is it safe to merge confidential purchasing documents using a free online tool?

It depends on the tool's architecture. If the tool explicitly states it processes files locally in the browser—meaning the files never leave your device—then it is safer than a tool that uploads files to a server. Always read the tool's privacy policy before uploading sensitive documents.

Q3. What if my purchase order is emailed as a PDF but the delivery note came as a scanned image?

Merge the PDF versions of both documents. If the delivery note existed only as a physical paper document, scan it using your Mac's scanner or a phone scanning app, save it as a PDF, and then follow the merge steps above. The merge tool will combine the scanned PDF with your purchase order PDF. Note that the scanned PDF will lack a text layer unless you run OCR (optical character recognition) on it first.

Key Facts

• A browser-based PDF merger that processes files locally eliminates the need for software installation and keeps sensitive logistics documents on your device.
• The order of files in the merge queue determines the resulting page order; place the purchase order before the delivery note for a logical reconciliation sequence.
• Merged PDFs should preserve the original text layer, enabling search and text selection inside Preview on your Mac.
• Free-tier browser-based tools may impose file size limits, so check limits before merging large, scan-heavy documents.
