Plan the sale. Set the dates. Let Kairii handle the prices.
Stop changing WooCommerce sale prices by hand. Kairii puts your promotions on a visual calendar, applies discounts automatically when a sale begins, and restores normal pricing when it ends. Choose the products, set the offer, preview the results, and protect your minimum profit — all from one workspace.
Schedule sales without the last-minute rush
- Plan promotions on a month-by-month calendar, with a sale editor directly beneath it.
- Set start and end dates, choose products or categories, and discount from selling price or margin.
- Preview sale prices, earnings and exclusions before a promotion goes live.
- Fine-tune individual products with their own discount, fixed price or exclusion.
- Display a sale badge and price message on eligible shop products.
- Kairii applies prices dynamically rather than overwriting your products’ stored prices.
Protect your margins automatically
- Set minimum profit safeguards so discounts are capped before they fall below known cost plus your required profit.
- Use WooCommerce product costs or manage category-based costs and margins.
- Keep existing WooCommerce sale prices in control: promotions do not stack.
- Exclude products with unknown costs from Kairii discounts.
- Review the live pricing table to see exactly which products qualify.
Make every occasion an opportunity
- Start with ten familiar retail occasions, including Valentine’s Day, Black Friday and Christmas.
- Add your own occasions, anniversaries and birthdays.
- See upcoming occasions and running promotions from the WordPress dashboard.
- Get optional email reminders and a practical promotional checklist.
- Review sales performance using paid WooCommerce orders.
Free and Pro
Kairii Free includes calendar-based sale planning, automatic sale start and end, margin protection, product selection, previews, and the starter occasions.
Kairii Pro extends your planning with the full library of 1,500+ international and specialist occasions, annual repeating sales, additional fulfilment providers, and advanced price-list features.
Less manual price editing. More time to plan the next promotion.
Uninstall
Deactivating Kairii stops its sales at once and removes nothing.
Deleting Kairii keeps your data by default, so reinstalling picks up where you left off. To remove everything, switch on Settings Data “Remove all Kairii data when the plugin is deleted” before you delete the plugin. Kairii then removes its occasions and sales, all of its settings (including the price list and its rules), the reminder settings kept for each user, the price-list links on products, and the sale notes it adds to order lines.
Your products and prices are never changed by Kairii, so there is nothing to undo. Costs in WooCommerce’s own Cost field stay, as they are your WooCommerce data, and your orders and their totals are untouched.
External services
Occasion date updates (optional). Festivals that follow the moon ship with checked dates for a few years at a time. When you press “Check for updates” in Kairii Settings, or switch on the monthly check, Kairii downloads one signed file of occasion dates from robart-illustration.eu (https://robart-illustration.eu/wp-json/wprobarts/v1/kairii-occasions). Nothing about your site or shop is sent — it is a plain download. Kairii never contacts the server unless you press the button or switch on the monthly check.
