The Info Product Business Tech Stack: Checkout, Subscriptions, Email and Tracking

The 7 layers of an info product tech stack, platform fees compared (November 2026), and the 3 decisions that are hard to undo: cards, access, proof.

Article summary

TL;DR

An info product business (courses, coaching, memberships, ebooks) runs on seven layers: sales pages, checkout and offers, payments, billing, course delivery, email, and tracking. Most tools are easy to swap. Three decisions are not: who processes payments and holds the cards, how a payment turns access on and off, and where proof of access is stored. Settle those first.

Platform fees vary widely: Teachable charges 7.5% per sale on its Starter plan, Podia 5% on Mover, Stan none (November 2026).
Stripe does not name courses or coaching in its restricted list; it prohibits "get rich quick" schemes and "high-pressure upselling" (read November 2, 2026).
To fight a Visa fraud dispute on digital goods, you need 2 or more data points such as IP, device or logins after purchase (Visa rules, October 2026).
Visa forbids charging interest on merchant payment plans and requires a separate consent before storing the card.
Leaving a platform is a project: Kajabi says most subscription and payment plan migrations take "1 to 3 weeks", and "PayPal subscriptions cannot be migrated at this time" (read November 3, 2026).

The 7 layers of an info product stack

Each layer has one job. The third column is what changes when what you sell is access, not a parcel.

Layer	Its job	What info products need	Examples of tools
1. Sales pages	Explain the offer, capture leads	Clear outcome without income promises; refund terms visible	Funnel builders, site builders
2. Checkout and offers	Turn visits into orders	Order bumps, one-click upsells, payment plans	Native checkout, funnel and checkout tools
3. Payments	Take the money	A processor that understands your offer, plus a backup	Stripe, PayPal, platform payments
4. Billing	Renewals and installments	Memberships, fixed payment plans, retries on failure	Platform billing, subscription tools
5. Delivery	Host the course or community	Access granted on payment, removed on failure or refund; login logs	Kajabi, Teachable, Thinkific, Circle
6. Email and SMS	Onboard, remind, recover	Welcome and access emails, payment reminders, failed payment notices	Kit, ActiveCampaign, Klaviyo
7. Tracking	Tell ad platforms what sold	Server-side purchase events, upsells counted	Meta CAPI, Google, TikTok

Your stack, layer by layerWhat changes when you sell access, not a parcel

1. Sales pages: Clear outcome, refund terms visible
2. Checkout and offers: Order bumps, one-click upsells, payment plans
3. Payments: A processor that understands your offer, plus a backup
4. Billing: Retries on failure, then suspend
5. Delivery: Access on payment, login logs as proof
6. Email and SMS: Access emails, failed payment notices
7. Tracking: Server-side purchase events, upsells counted

Highlighted: the links that are hard to undo.

Payment turns access on, failure suspends it, logins prove it.

All-in-one platform or separate tools?

An all-in-one course platform covers layers 1, 4, 5 and 6 with one login. You pay for it with platform fees, and you often accept its checkout and its payment provider.

Platform	Monthly plan (monthly billing)	Platform fee per sale
Kajabi	Basic $179, Growth $249, Pro $499	None with Kajabi Payments ("Kajabi does not take a revenue share as a platform"); 2%, 1% or 0.5% with a third-party processor (Kajabi)1
Teachable	Starter $39, Builder $89, Growth $189	7.5% on Starter, 0% above ("Standard payment processing fees may still apply") (Teachable)2
Podia	Mover $49, Shaker $99, Earthquaker $179	5% on Mover, none above (Podia)3
Stan	Creator $29, Creator Pro $99	"Stan doesn't charge transaction fees" (Stan)4

Prices read November 2, 2026, checked again November 3. Processor fees come on top in every case.

Separate tools make sense when one of these is true:

Fig. 2Three reasons to split the stack

Your offers outgrow the platform checkout
Bumps, upsell sequences, A/B tests, several payment plans.
You need your own processor, or more than one
A platform that forces its payment provider leaves you with no backup.
You sell beyond courses
Coaching, events, physical workbooks, a community.

Watch out

The more tools you connect, the more places access can break. A student who paid and cannot log in becomes a refund request, then a dispute.

How many tools is normal? Vendors give different answers: FitBudd writes that "Most online coaches use 4-6 tools"12; The Coaches Console says the average coach pays for "6-8 different software tools" and "Most could get by with three"13. Count jobs, not logos: one tool can cover several layers.

The 3 decisions that are hard to undo

1. Who processes payments, and who holds the cards. Stripe does not name courses or coaching in its list. It prohibits offers that "promise fast and easy money", "high-pressure upselling" and "fake testimonials"5. If the cards sit with a platform you cannot leave, changing processors means asking every member and plan payer to re-enter a card.

Check what a move actually carries over:

Stripe exports cards, not billing. It transfers card data only "to another PCI DSS Level 1-compliant payment processor", and "doesn't export your account's payment history, subscriptions, or other objects"15.
Platform migrations have gaps. Moving Stripe plans into Kajabi Payments skips paused and past-due subscriptions, doesn't support Link or ACH, and can't move PayPal subscriptions14.
It takes time. "Most migrations are completed within 1 to 3 weeks of the initial request" (Kajabi)14.

1 to 3 weeks

Most migrations into Kajabi Payments

Retries at most by default on Kajabi Payments, then the plan is canceled

Compelling evidence items for a Visa digital goods fraud dispute

Kajabi Help Center, read November 3, 2026; Visa Core Rules, October 24, 2026, Table 11-7.

2. How a payment turns access on and off. Access should follow billing events, not a manual check: grant on payment, suspend on failure, remove on refund. Decide when "failure" starts. On Kajabi Payments, the default waits: Stripe retries "up to 4 times over the course of several weeks", then the plan is canceled, "which revokes product access"; you can switch to revoking after the first failed payment16. The details are in how to cut access when a payment fails.

3. Where proof of access lives. For a Visa fraud dispute on digital goods, the compelling evidence list includes the IP address, device ID, and proof the buyer used your site or app "on or after the Transaction Date"; you need 2 or more6. PayPal accepts "a system of record" showing the item was sent or "accessed by the recipient"7. If your course tool keeps no login history you can export, you have nothing to send.

How the layers connect

The stack works when each billing event triggers the right action everywhere.

Event	Delivery	Email	Tracking
First payment	Grant access, log it	Welcome and login email	Purchase event from the server, deduplicated with the pixel8
Upsell accepted	Add the module or program	Access email for the upsell	Separate purchase event
Installment or renewal fails	Keep access during retries, then suspend	Card update request	None
Plan completed	Keep full access	Confirmation	None
Refund or cancellation	Remove access	Confirmation	Refund recorded

First paymentGrant access, log itWelcome and login email
Upsell acceptedAdd the module or programAccess email for the upsell
Installment or renewal failsKeep access during retries, then suspendCard update request
Plan completedKeep full accessConfirmation
Refund or cancellationRemove accessConfirmation, refund recorded

Event, then delivery, then email.

Payment plans add their own rules. Visa requires the plan terms, total price and schedule to be shown "separately from the general purchase terms" and accepted before you store the card, and no interest6. See payment plans for info products.

The stack by stage

Stage	What you need	What can wait
First launch	One course platform, a checkout, one processor, a welcome email, server-side purchase tracking	Separate funnel tools, SMS
Proven offer	Order bump and upsell, a payment plan, failed payment emails, login logs you can export	Multi-touch attribution
Scale	A backup processor and routing, A/B tests, a membership with retention offers, access driven by webhooks	Anything that duplicates billing or tracking

Frequently asked questions

What tools do I need to sell an online course?

Enough to cover seven jobs: a sales page, a checkout, a payment processor, billing for memberships or payment plans, a place to host the course, email, and tracking. Many creators start with one course platform that covers most of them, and add separate tools only when the checkout or the payment setup limits them.

Should I use an all-in-one platform or separate tools?

Start all-in-one if you sell one course and want few moving parts. Compare the platform fee per sale (from 0% to 7.5% on entry plans as of November 2026). Move to separate tools when you need upsell sequences, payment plans, your own processor or a backup.

Can I use Stripe for online courses and coaching?

Stripe's restricted list, read November 2, 2026, does not name courses or coaching. What it prohibits is the promise: "get rich quick" schemes, outrageous claims, fake testimonials and high-pressure upselling. A course sold on a skill is not the issue; a course sold on income claims is. Details: Does Stripe allow info products?

How do I connect payments to course access?

Through billing events. Your checkout or billing tool sends a webhook when a payment succeeds, fails or is refunded, and your course platform grants, suspends or removes access. Test the failure path before launch, not only the purchase path.

What happens to my members if I leave my course platform?

It depends on who holds the cards and the billing. Stripe can export card data to another PCI DSS Level 1 processor, but not subscriptions or payment history, so plans must be rebuilt on the new side. Platform migrations skip some cases: Kajabi can't move PayPal subscriptions, and most migrations take 1 to 3 weeks. Plan the move before the launch, not during it.

What data should my stack keep for chargebacks?

For digital goods, Visa lists the IP address, device ID, the buyer's name and email linked to their account, and proof they used your site or app on or after the purchase date; you need 2 or more. Keep login and lesson logs with dates. More in info product chargebacks.
