Order Preparation & Picking (dfpicking) — Complete Guide

Overview

dfpicking speeds up order preparation in PrestaShop 8 and 9. The module groups several orders into a single picking list, aggregates quantities per product and stock location, supports barcode scanning (EAN13, UPC, ISBN or reference), switches orders to the native processing-in-progress status and prints the picking list and price-free packing slips as PDFs.

Installation

1. Back office → Modules → Module Manager → Upload a module.
2. Upload dfpicking.zip and click Install.
3. A new Orders → Order preparation (picking) tab appears in the menu.

Configuration

Go to Modules → dfpicking → Configure:

• Eligible order statuses — orders with these statuses can be added to a picking list (default: payment accepted).
• Status applied when preparation starts — applied to each order added to a list (default: the native PrestaShop processing-in-progress status).
• Status applied when finished — optional status applied when the list is closed (default: no change).
• Status change email — whether the native customer email is sent on status changes (default: disabled).

Creating a picking list

1. Open Orders → Order preparation (picking) and click New picking list.
2. Tick the orders to prepare (a select-all checkbox is available).
3. Click Create the picking list.

The selected orders immediately switch to the configured preparation status. Orders already in an open list are automatically hidden to prevent double preparation. Refunded or returned quantities are excluded.

Preparing with barcode scanning

The preparation screen offers two views: aggregated products (all orders combined, sorted by location) and per-order detail. Place the cursor in the scan field — it stays focused automatically — then scan each item:

• Recognized codes: EAN13, UPC, ISBN and product or combination reference.
• Each scan is allocated to the oldest order not yet served for that product.
• High beep = item ticked; low beep = unknown code or already complete product.
• Completed rows turn green and the global progress bar updates in real time.
• The + / − buttons on each row allow manual adjustment (product without barcode, breakage, etc.).

Printing documents

Picking list PDF

The Picking list PDF button generates a document aggregated per product: location, reference, EAN13, total quantity, per-order breakdown and checkbox.

Packing slips PDF

The Packing slips PDF button generates one slip per order, deliberately without prices: delivery address, carrier, total weight and product list with checkboxes. Slip it into the parcel.

Finishing the preparation

Once everything is ticked, click Finish preparation: the list switches to “Done” and, if configured, orders receive the closing status. An Order preparation panel on each back-office order page shows the linked lists and their progress.

Troubleshooting

• “Unknown code” when scanning — check that the EAN13/UPC/reference is filled in on the product (or combination) sheet and that the product belongs to the current list.
• No sound — browsers require a user interaction before playing audio: click once in the page, then scan.
• An order does not appear at creation — its status is not among the eligible statuses, or it is already in an open list.
• Empty location — the location field in Catalog → Stocks is not filled in; the list is then sorted by reference.

Uninstall

Uninstalling removes the module tables (dfpicking_list, dfpicking_item), its configuration and its menu tab. Your orders and their statuses are not modified.
