Do I need one combination per device?

No. Combinations carry the grade (for example 128 GB Black grade A) and devices are units attached to those combinations. Ten grade A devices give a stock of 10 on the grade A combination.

What happens if two customers want the same piece?

In unit mode, adding to the cart reserves the piece with an atomic database update: the second customer gets the message "Another customer has just reserved this piece". The reservation lasts 30 minutes by default and can be changed.

Can I sell a unique piece at a different price from the others?

Yes, in unit mode. Each unit can have its own sale price excluding tax. It is applied through a cart-specific price, so the invoice and VAT stay native. Catalog price rules do not apply to these pieces.

Is stock entered by hand kept?

No. On a refurbished product, the stock of each grade combination is recalculated from the available units. A resynchronise button updates the counters after a catalog import or a manual edit.

What happens to the unit if the order is cancelled?

You choose the order statuses that release units (cancelled and payment error by default) and whether they go back to "available" or "returned" for an inspection before resale. The event is written to the unit history.

Is the full serial number visible publicly?

By default the public sheet only shows the last 4 characters. The full number appears on the order line, the invoice and the buyer's certificate, reached through a private link from their account.

PrestaShop Refurbished Products Module 8 & 9: Grades and Serial Numbers

Sell Refurbished Products on PrestaShop 8 & 9: Condition Grades, Serial Numbers and Unique Items

Every device has its sheet, every grade its price, and the stock follows what is really on the shelf.

A refurbisher has 40 smartphones of the same model, each with its own condition, battery and scratches. Without a module, they create one combination per device or describe everything in the product text, and the stock never matches the devices on the shelf. With this module, each device is a unit with its serial number and photos, the stock of each grade is calculated automatically, and the customer chooses a grade or the exact piece they will receive.

At a glance

Grades A, B, C (and more) carried by native combinations: cart, order, invoice and stock stay native
One sheet per serial number: photos, battery health, test checklist, notes, history
Stock of each grade equals the number of available units, piece reserved in the cart

A detailed look at how Sell Refurbished Products on PrestaShop 8 & 9: Condition Grades, Serial Numbers and Unique Items works, why we built it the way we did, and the thinking behind the features above.

§ 01

Why PrestaShop alone is not enough for refurbished goods

PrestaShop knows the "refurbished" condition of a product, but not the condition of each device. A refurbisher sells pieces that each have a serial number, a battery, scratches and a history. This module adds that unit level without leaving the native model: grades are combinations, and each grade combination has a stock equal to the number of available devices.

§ 02

Grades, prices and stock

Grades A, B and C are created at installation with their color, description and default price impact (0, -10 and -20%). You can add more, rename them in each language or deactivate them. On each product, one button creates the grade combinations from the existing combinations (capacity, color) and another applies prices. Stock is no longer typed by hand: it follows the units.

§ 03

Selling by grade or by piece

For a catalog of comparable devices, grade mode is enough: the customer chooses a condition and the unit is assigned when the order is validated. For unique pieces, unit mode shows each device with its photos and tests; the customer adds the exact piece to the cart, it is reserved for them, and it can have its own price. The serial number is added to the order line and the invoice.

§ 04

Buyer confidence

Each unit has a public sheet with photos, battery and checklist, with the serial number masked. In their account, the buyer finds a condition certificate with the full number and the warranty end date, which they can print. The guide window explains what each grade means and which checks are made on every device.

§ 05

Day-to-day in the workshop

Units are added one by one (the serial number field accepts a barcode scanner) or by CSV import. The list shows the photo, grade, status and own price, with bulk actions. The dashboard gives the stock value at cost price, the average age of the stock, devices on sale for more than 60 days and the gross margin of the last 30 days. QR labels print on standard A4 sheets.
