Tiers
Half price for the first hour, early-bird until the date, full price on the day. Each tier has its own price and its own page. First active tier wins; expired tiers fall through to the next.
40 speakers, live and on replayWhat Jane sees, 12 minutes after enrolling
Price locks when the checkout session starts. If a tier expires mid-payment they still get the price they started with.
Countdowns
Pick a style, then edit every colour, font and label. One design renders on the page, at checkout and as a GIF in email.

PostmarkWhat you can do
Set the deadline once. The countdown, the price and the checkout all move together.
One sitewide deadline, the same for everyone. The price and the coupon die at the same second the banner does.
Doors open Monday, close Friday at 9pm. Founding price while they are open, standard price after.
Every subscriber gets their own window from the moment they first visit. A March lead sees what a January lead saw.
One price for the thirty minutes after the welcome email opens. It never comes back, and they know it.
The offer closes 48 hours after the live session. The same countdown ticks in the replay email and on the checkout.
Enrolment shuts on a date. After that the same link lands on the waitlist page, not a dead offer.
The first hundred get the founding price. Seat 101 sees the next tier, with the count on the page.
Same dates every year. It switches itself on, runs, and switches itself off without anyone remembering.
Built into the checkout
A countdown script can only count down. Here the active tier picks the price the checkout charges, and bumps, upsells, coupons and split-pay all still work on top of it.
On top of the tier
The tier only decides the base price. Everything else in the checkout carries on around it, the same as any other order.
Coupons and bumps apply on the tier price. The buyer sees one total, and it is the one they pay.
Using Stripe Checkout, ThriveCart or Shopify? Ask for the tier and pass its price along. Plandalf is the promo brain either way.
Results
Every promo has a live overview, and because the checkout is ours, the revenue is attributed to the promo. Not guessed from a pixel on a thank-you page.
Enrolled, active, converted and revenue for every promo, with the rate between them and the daily trend.
Email open, link click, affiliate, automation, API or CSV. Search it, filter it, export it.

Controls
A live campaign has two switches, and neither one touches the people already enrolled.
Stop enrolling new people while everyone already in keeps their deadline.
Send anonymous traffic to the best price, or hold the early-bird tier for confirmed enrolments.
For developers
You don't need any of this. A buy button and a countdown tag do the whole job. This is for when you want to route the promo yourself.
One attribute on any buy button. The checkout opens at the active tier's price and locks it for the session.
Add ?pf_ref= to any link from email or ads. The first visit starts their clock; every visit after finds the same one.
Enrolment, tier changes and the redirect to the right page all happen on their own. Most sites stop here.
<!-- The whole integration -->
<a data-plandalf-present="summit"
data-plandalf-apply-promo="summit_early_bird">Buy</a>
<div data-plandalf-promo="summit_early_bird"></div>
// Optional: read the answer yourself. Try it: press Skip to deadline below.
const promo = await plandalf.promo("summit_early_bird")
promo.activeTier.label // "early_bird"
promo.activeTier.price_amount // 9900
promo.remaining // 1740 (seconds)
// Tier changes stream as events; your page repaints, no reload
for await (const e of promo.events) {

}Every promo has one. Any ESP, Zapier, n8n or your own backend can enrol with a POST.
$ curl -X POST app.plandalf.com/hooks/catch/… \
-H "Content-Type: application/json" \
-d '{"email":"jane@example.com","ref":"jane@example.com"}'No integration at all: put the ref in the URL and the SDK picks it up on landing. Same person, same clock, every visit.
