Checkouts

Create the thing you sell, shape the buying flow, and put it on your site.

• Offers overview — Understand Plandalf Offers: hosted checkout pages, embedded checkout flows, products, prices, add-ons, order bumps, upsells, save offers, and purchase context.
• Create your first offer — Create a checkout offer that can be hosted, embedded, tested, and connected to follow-up workflows.
• Templates — Use offer templates to start from a proven checkout structure instead of building every page from scratch.
• Design your checkout — Customize offer pages, blocks, themes, mobile behavior, and brand details without changing your site embed code.
• Products — Attach products and prices to offers so checkout sessions, invoices, and integrations carry clean catalog context.
• Pricing models — Model one-time prices, subscriptions, tiered pricing, volume pricing, trials, discounts, and promo-driven price changes.
• Add-ons and variants — Let customers add related products, variants, upgrades, and optional line items during checkout.
• Multi-page flows — Split longer checkouts into focused pages for plan selection, buyer details, payment, upsells, and confirmation.
• Add to your site — Add Plandalf offers to any site with declarative attributes or programmatic SDK calls.
• Buy buttons — Create buttons and links that open a Plandalf offer in the right frame with the right customer and promo context.
• Returning customers — Use identity and session continuity so returning customers can resume a checkout or buy with the right account context.
• Hosted checkout — Plandalf's hosted checkout — managed URL, theme-able down to fonts and layout, with test and preview sessions.
• Order bumps — Add a one-click companion product inside the same checkout, then test the selected line item, invoice, taxes, coupons, webhooks, and automation context.
• Save offers — Present a discount, plan switch, pause, or deadline-bound offer when a subscriber starts a cancellation path.

Promos

Set up deadlines, countdowns, tiers, and the checkout handoff.

• Timers and promos overview — Use Plandalf timers and promos to coordinate deadline campaigns across pages, emails, CTA links, and checkout prices.
• Countdown timers — Embed countdown timers on pages and in email while keeping the timer connected to the campaign state.
• Create a promo — Create a deadline promo that can drive countdowns, active tiers, redirect targets, and checkout price changes.
• Tiers and timing — Model campaign phases so each deadline window can change copy, CTA targets, and checkout prices.
• CTA links and redirects — Use promo links and participant references so campaign CTAs send each visitor to the right destination.
• Embedded promos — Embed a promo countdown and a Plandalf checkout on the same page so deadline state and pricing stay aligned.
• Hosted landing pages — Use Plandalf-hosted promo pages when you want the campaign URL, deadline state, and checkout handoff in one place.
• Promo reporting — Track promo participants, tier state, CTA clicks, checkout handoff, and paid outcomes for deadline campaigns.
