DataFirefly Group Buy & Collective Tiered Pricing

Group buying and collective tiered pricing for PrestaShop 8 and 9: the more buyers, the lower the price for everyone.

Turn your customers into a sales force. Define collective price tiers: as orders pile up, the unit price drops for all buyers. The current price applies natively everywhere (product page, listings, cart), a progress bar and countdown create urgency, and an optional retroactive refund guarantees everyone pays the best price reached. And a customer who orders in bulk instantly unlocks the tier matching their quantity.

What it does

The short version.

01

The price drops for everyone

Define tiers (buyer threshold to price). When a tier unlocks, the new price applies to all buyers in real time, via PrestaShop's native specific prices.

02

Automatic retroactive refund

Best-price-for-all option: when the price drops, earlier buyers automatically receive a discount voucher for the difference, with an email notification.

03

The quantity price, right away

In units mode, a customer ordering 10 at once instantly gets the tier-10 price on their order, without waiting for the collective count to reach it.

04

Counter, progress and countdown

A product-page widget shows the collective counter, a progress bar to the next tier and a countdown, all refreshed live without reloading.

05

Three counting modes

Count by number of orders, units sold or distinct customers, with an option to keep only valid orders.

06

No CRON, driven by orders

Recalculation triggers on every order and every status change. No scheduled task to configure or monitor.

The long version

Everything you'd want to know before you install.

A detailed look at how DataFirefly Group Buy & Collective Tiered Pricing works, why we built it the way we did, and the thinking behind the features above.

§ 01

Collective pricing that rewards your customers

Group buying flips the logic of the classic promotion: instead of a fixed discount, the price drops as the community buys. You define tiers (for example 18 € from 10 buyers, 15 € at 50, 12 € at 100) and DataFirefly automatically applies the reached tier's price to all buyers, via PrestaShop's native specific prices. The price shows everywhere without touching your theme.

§ 02

Everyone at the best price, even the first ones

Enable the retroactive refund: as soon as a lower tier unlocks, buyers who already ordered automatically receive a discount voucher for the price difference, along with an email. Your first customers are never penalised for backing the operation early, a powerful and rare conversion argument.

§ 03

The quantity price, immediately

In units mode, a customer ordering ten at once clears the ten-unit tier on their own: they instantly get the matching price on their order, without waiting for the collective count. The logic stays best-price-for-all: if the collective price is already lower, that one applies. Everything goes through native specific prices, so the right price shows from the cart.

§ 04

Urgency and social proof driving conversion

On the product page, a widget shows the collective counter, a progress bar to the next tier, the full price ladder and a countdown to the campaign end. It all refreshes live via AJAX, at an interval you choose. The visitor sees the dynamic in real time and understands that buying now, and inviting others to do so, lowers the price.

§ 05

Three counting modes, zero maintenance

Choose to count by number of orders, units sold or distinct customers, and restrict to valid orders if needed. Recalculation triggers automatically on every order and every status change: no CRON to configure. The module is multilingual and multistore, compatible with PrestaShop 8 and 9, and shipped in five languages.
