Shipping Automation
Amazon and Flipkart Label Workflow Guide: Complete Seller Walkthrough
By Nikunj Maniya · 8 May 2026 · Updated 9 June 2026 · 4 min read
If you are shipping daily orders from both Amazon and Flipkart, your label printing process decides how fast your warehouse runs. This guide explains both functionalities in simple language, so someone new to marketplace dispatch can understand exactly what happens after uploading a PDF and why each step matters.
What the cropper does when you upload a marketplace PDF
The workflow is designed for one goal: turn marketplace PDFs into print-ready thermal labels that can be dispatched without courier issues. The system:
- Detects whether the uploaded PDF is Amazon or Flipkart format.
- Removes invoice-only pages where needed.
- Crops label content to keep barcodes and route sections intact.
- Converts output to 4x6 thermal-friendly layout.
- Supports batch processing so sellers can print many orders quickly.
For users, the experience is simple: upload file, verify platform, generate output, print at "Actual Size".
Open the free Ecom Insides label cropper on your desktop or phone browser, then compare with our Flipkart Ekart label printing guide if you ship on both channels.
Amazon functionality: how it works in detail
Amazon label PDFs usually contain both shipping and invoice information in a mixed structure. This is why Amazon processing needs careful crop logic and page filtering.
1) Input format you receive from Amazon
- Most exports come as A4-size pages.
- Shipping label section and invoice section can appear on the same page.
- Some batches include extra invoice continuation pages.
2) Critical fields the processor preserves
- AWB barcode (primary courier scan key)
- Ship-to / ship-from blocks with PIN code details
- 2D barcode / routing marker used in hub sorting
- Order identifiers for pack and dispatch validation
3) What gets removed or transformed
- Invoice-heavy areas are trimmed from thermal output.
- Unnecessary extra pages are excluded from final print file.
- Label content is resized into a thermal-compatible layout.
4) Seller-facing result
Users get a compact output PDF that prints cleanly on thermal printers, with important courier-readable sections preserved and non-essential invoice content removed. For the field-by-field anatomy, see the Amazon shipping label format explained.
Flipkart functionality: how it works in detail
Flipkart (Ekart) PDFs are often cleaner for automation because labels and invoice pages are usually separated in an alternating pattern.
1) Input format you receive from Flipkart
- Order batches typically export as multi-page PDFs.
- Odd pages usually contain label content.
- Even pages are often invoice or supplementary paperwork.
2) Critical fields the processor preserves
- Ekart route code at the top section
- AWB barcode for scan validation
- COD markers and address blocks when applicable
3) What gets removed or transformed
- Invoice-only pages are discarded automatically.
- Label margins are trimmed for thermal dimensions.
- Output is arranged for faster batch printing.
4) Seller-facing result
The final file is easier to print in bulk and usually faster to process than manual page-wise printing from Seller Hub exports.
Amazon vs Flipkart: quick comparison
| Area | Amazon | Flipkart |
|---|---|---|
| Source layout | A4 with mixed label + invoice sections | Alternating label and invoice pages |
| Automation complexity | Moderate to high | Low to moderate |
| Invoice handling | Detect and trim invoice regions/pages | Discard predictable invoice pages |
| Crop strategy | Template-aware with label-section boundaries | Page selection + margin trim |
| Typical output quality | Excellent when barcode area is preserved | Very consistent for bulk output |
End-to-end user flow
- User uploads an Amazon or Flipkart PDF batch.
- System identifies platform using PDF characteristics.
- User confirms layout and output settings.
- Tool processes pages, crops labels, and removes non-label content.
- User downloads final print-ready PDF.
- User prints with thermal settings at actual size.
Common mistakes and how this workflow prevents them
- Manual cropping errors: automation prevents cutting off barcode or route blocks.
- Printing invoices by mistake: invoice pages are auto-filtered where possible.
- Scan rejection from scaling: output is optimized for fixed thermal dimensions.
- Slow dispatch on high-volume days: batch-ready PDF output reduces per-order effort.
Always print with scaling disabled. "Fit to page" can shrink barcodes and lead to pickup scan failures even when the label looks visually correct.
Why this matters for first-time visitors
New users usually do not care about PDF internals. They care about one outcome: labels that print quickly and get accepted by couriers. By clearly separating Amazon and Flipkart functionality, the workflow helps users trust the process and adopt the tool faster.
Frequently asked questions
Can I process both Amazon and Flipkart files in the same day?
Yes. The workflow supports both platform formats, and each file is processed with its own platform-specific logic.
Do I need to manually remove invoice pages before uploading?
No. The processor is designed to detect and remove invoice-only areas/pages automatically in most cases.
What printer settings should I use for best output?
Use thermal 4x6 paper, print at Actual Size, and keep page scaling turned off to preserve barcode readability.
Is this useful for small sellers with 10-20 orders/day?
Yes. Even lower daily volume benefits from fewer manual errors and faster packing flow.
