Seller Flex label + invoice matched by invoice number, PDF or ZPL labels
Labels and invoices are processed directly inside your web browser. No data leaves your machine.
Seller Flex orders come with shipping labels and invoices in separate files, and pairing them by hand takes time. Quick Cropper's Amazon Seller Flex Label Crop combines your Seller Flex shipping labels and invoices into one PDF, with each invoice placed right after its label. Upload labels as a PDF or ZPL file (or paste ZPL code), add the invoice PDF, and the tool matches them by invoice number automatically.
Our tool is built to take the manual work out of Seller Flex shipping. It pairs every label with its invoice even when the invoice PDF is in a different order, prints the quantity, SKU, description and MRP on each label, and offers SKU sorting, order numbers, 4 labels per A4 page and an order summary. Whether you ship a handful of orders or hundreds a day, it keeps your labels and invoices organized - free, unlimited and private, with everything processed in your browser.
Every label gets its own invoice, even if the invoice PDF is in a different order or an invoice runs over more than one page.
Works with label PDFs, ZPL files and pasted ZPL code. A single PDF that contains both labels and invoices is supported too.
Quantity, SKU and the full product description are printed on the label, one line per product.
The MRP is calculated from the invoice amount and quantity and printed in bold, marked "(Incl. of all taxes)".
Sort orders by SKU and print a running order number on each label for easier packing and counting.
Print four labels on each A4 sheet, with invoices following in the same sequence.
Download a summary of SKUs, quantities and orders to plan picking before you pack.
Matching Seller Flex labels and invoices takes just a few clicks.
