Some parcels cannot leave the packing table without a bill inside them. This mode keeps every Meesho tax invoice attached to the label it belongs to, so what you shipped and what you billed never come apart.
Pick Label with Invoice in the Sort by panel before you crop. Standard crop and sort cost no coins.
Buyers ask for one. Your accountant wants the GST copy sitting against the batch you actually dispatched. Bulk and reseller orders get refused at the door when the box has no paperwork in it. For those orders, a cropper that silently deletes the tax invoice is throwing away the document that proves what you sold and at what value.
A Meesho page already carries both: the shipping label on top, then the TAX INVOICE line, then the Bill To / Ship To block and the copy marked Original For Recipient. Choose Label with Invoice and no crop is applied at all — every page comes out whole, at its original size, reordered but never cut. Label and bill are the same piece of paper, so nobody can pair one order's label with another order's invoice.
Because nothing is cropped, the output is still a full-size page, so this is an A4 job — the thermal roll belongs to labels-only batches. Archive the finished PDF and you hold a dated record of what shipped and what was billed, in packing order. When a buyer disputes an item or an RTO parcel comes back contested, that file is your evidence.
