Subscription Billing for Online Pharmacies

How to bill prescription refills on subscription: follow the prescription, charge on shipment, stop when refills run out, and pick a tool that fits.

Nick Bonnassies, CMO at Tagada · checked against 12 sources

Article summary

TL;DR

A pharmacy subscription bills each refill the prescriber has authorized, ideally on the day it ships, and stops when refills run out or the prescription expires. Show the terms before the first order, get express consent, and let customers pause, skip, change their card or cancel online. The tool must follow the pharmacy's dispensing, not a fixed calendar date.

Federal law allows a prescription drug to be refilled only "if such refilling is authorized by the prescriber".
Tagada Rx rebills "the day the pharmacy ships", not on a calendar date, with a 30-day default cycle.
Stripe found that 25% of lost subscriptions are lost to failed payments (January 2024).
Shopify Subscriptions works only with listed gateways, and Shopify Payments excludes prescription drugs.

This guide is part of our playbook on the best ecommerce platform for online pharmacies. The general guide, for any business: subscription payments. When to sell on subscription and how to keep subscribers is in subscriptions and churn for online pharmacies.

What makes pharmacy subscriptions different

A regular subscription ships the same product until the customer cancels. A pharmacy subscription depends on a prescription that has its own limits.

	Regular subscription	Pharmacy refill subscription
What allows the next order	The customer's consent	The consent, plus an authorized refill1
When it ends	When the customer cancels	When the customer cancels, refills run out or the prescription expires
Quantity	Chosen by the customer	Set by the prescription
Renewal	Automatic	Needs the prescriber when refills run out
Data involved	Order and payment	Order and payment; prescription data stays in the pharmacy system

Billing ends with the prescription, not only with a cancel button.

Illustrative example.

Your subscription tool needs one input from the pharmacy system: can this refill ship? If not, no charge.

Bill on shipment, not on a date

Charging on a fixed date creates orders that are paid but can't ship: a refill not yet authorized, a prescription that expired, a pharmacist question. Billing when the pharmacy ships avoids that.

Refill due. The tool flags the subscription a few days before the cycle date.
Pharmacy check. The pharmacy confirms a refill is authorized and the order can be filled.
Reminder. The customer gets a notice with the amount and the ship date.
Ship and charge. The card is charged when the order ships.
No refill left. The tool pauses the subscription and the customer is told to renew the prescription.

No authorized refill, no charge.

Tagada Rx, the stack Tagada runs for prescription brands, works this way: recurring orders rebill "the day the pharmacy ships" and the default cycle is 30 days2.

Watch out

A subscription that keeps charging after the last authorized refill leads straight to refund requests and disputes. Tie the end of billing to the prescription, not only to a cancel button.

The billing rules

A refill subscription is a recurring charge. US law and card network rules apply to it like any other.

Rule	What it requires
ROSCA (US law)	Material terms before billing, express consent, a simple way to stop recurring charges3
Visa	Express consent; trial terms shown separately; reminder before a trial ends; online cancellation4
Mastercard	Confirmation with terms and cancellation instructions after sign-up; online cancellation; notice before billing on cycles of six months or less5

Tagada follows Visa and Mastercard rules and the laws that apply to payments.

Let customers manage their refills

Let patients skip, pause or change an order themselves. Make each change a click, not a support ticket.

Skip
One refill without cancelling.
Pause
When the customer has supply left.
Change frequency
Within what the prescription allows.
Update the card
Before a charge fails.
Change the address
For the next shipment.
Cancel online
As Visa and Mastercard require4 5, with a retention offer if you have one.

Failed renewals have their own guide: failed payment recovery for online pharmacies. Stripe ties a quarter of lost subscriptions to failed payments6.

Frequently asked questions

How do automatic prescription refills work online?

The pharmacy keeps the prescription on file and ships each refill the prescriber authorized, on a set cycle. The customer agrees to recurring charges at sign-up and is charged for each refill, ideally when it ships. When refills run out, the pharmacy asks the prescriber for a renewal or the subscription pauses.

Can I charge a subscription before the refill ships?

You can, but it creates problems. If the refill isn't authorized or can't be filled, the customer has paid for nothing and will ask for a refund or dispute the charge. Charging on shipment avoids this; Tagada Rx rebills "the day the pharmacy ships".

Do customers need to opt in to automatic refills?

Yes, for the recurring charge. ROSCA requires the terms before billing and the customer's express consent, and Visa requires express consent for subscriptions. Use a separate, unticked choice at checkout and confirm the terms by email.

Can I use Shopify Subscriptions for an online pharmacy?

Only on a supported gateway. Shopify Subscriptions works with a listed set of gateways, and Shopify Payments does not support prescription drugs. Check that the processor that approved your pharmacy is on that list, or use a subscription layer that runs on your processor.
