The little things
All the little things, taken care of.
Receipts, invoices, leads, tax, coupons, install. The parts of selling nobody puts on a landing page, all in the same account as the checkout and built to the same standard.
Receipts and invoices
Your brand, all the way through the buying process.
Beautiful invoices and receipts. Set your logo and colours once; the email, the receipt page and the PDF all wear them.
Your logo and colours on everything after the sale
On the email, the receipt page and the PDF, with your address and ABN in the footer. Never a generic receipt with somebody else's name on it.
A receipt page, hosted for you
Every buyer gets one page with all their receipts from you, each downloadable as a PDF. Save it, come back later.

Coupons
Coupons that work in the flow.

Limits, expiry, one per buyer
Set the rules once. The checkout enforces them and tells the buyer why a code did not apply.
Counted against the code
Every use is logged to the coupon, so you know what each one cost and what it brought in.

Install
One script. In and out, replaces nothing.
Paste one tag into your site and every checkout you publish is live on it. Sits beside what you run; comes out as easily as it went in.
Low risk by design
Nothing to migrate, nothing to replace. Try it on one page, then everywhere. WordPress, Webflow, Squarespace, Framer, Shopify, or plain HTML.
Your Stripe or PayPal, as is
Cards go straight to the processor you already have. Plandalf keeps the invoice, line items and status with the sale.
Install the scriptOne tag. Same tag on every platform.

After the sale
Every checkout event triggers the right next step.
Paid, abandoned, failed, refunded, trial started, renewed. Plandalf handles the receipts, recovery emails and offers itself, then pushes the tags, access and deals into whatever you already run.

- Yours missing?We build it.
Every checkout event is a trigger
Not just the sale. Abandons, failed renewals and refunds fire too, so recovery and clean-up run themselves.
The commerce jobs are built in
Receipts, invoices, cart recovery, deadline offers, failed-payment retries, trial reminders. No third-party tool, no setup.
Everything else runs in your tools
Tags, lists, memberships, deals, Slack, a signed webhook, a Zap. If we do not plug into something you use, we build it.
For developers and SaaS teams
No code required.
All the code you want.
Everyone else installs one script and never reads this. This is the loop from "who is this" to "they're in".
- 1
Identify
A short JWT signed with your API key. Same person on both sides.
- 2
Gate
Name the feature and its offer. Your check fails, the checkout opens in place.
- 3
Grant
The gate resolves when they pay. Your webhook hears it too, so your backend stays the truth.
- 4
Manage
Saved cards, customer portal, cancel and win-back flows, failed-payment recovery.
