Heartly is a flash sale and countdown timer plugin for WooCommerce. Launch a time-limited sale on any product, show a live countdown timer that drives urgency, and apply the discount automatically at checkout — all without touching code. Built for WooCommerce store owners who want more sales from the traffic they already have.
Heartly connects your WooCommerce store to the Heartly platform: you create the flash sale in the Heartly dashboard, install this plugin once, and it handles the storefront countdown, the checkout redirect, and the campaign analytics for you. EU merchants get PAngV / Omnibus reference-price compliance built in.
What this plugin does
- Automatic checkout redirect: Customers who click “Go to Checkout” on a Heartly flash sale land directly on your checkout page with the product in their cart
- Coupon application: Discount codes from flash sale URLs are automatically applied at checkout
- Order tracking: Flash sale ID is saved to each order so you can measure campaign revenue
- Price history sync: Product price changes are forwarded to Heartly for PAngV compliance tracking
- Settings sync: Your checkout and cart URLs are kept in sync with the Heartly platform automatically
Who this is for
WooCommerce store owners who want to run flash sales without touching code. You create the campaign in the Heartly dashboard, install this plugin once, and it handles the storefront logic.
