Why it matters

Generic coupons break the moment someone shares one.

Most in-store promotions rely on codes that anyone can copy. You can't track who used them, and you can count on some abuse.

The old way

POS integrations take weeks

Connecting coupon logic to your POS means IT involvement, vendor calls, and a timeline measured in weeks or months.

Coupons get reused and shared

Screenshots go into group chats. The same “exclusive” code gets used dozens of times with no way to stop it.

No tracking, no accountability

You know you sent 5,000 coupons. You have no idea how many were actually redeemed by unique people.

With Coupon Carrier

Self-serve setup

No POS changes, no hardware, no IT. Create your offer, generate or import codes, and start distributing.

Every code is unique and single-use

Each customer gets their own code. Once redeemed, it’s locked. A screenshot or forwarded link can’t be redeemed a second time.

Every redemption logged

Staff verify offers in seconds. You see which vouchers were redeemed, when, and by which scanner login. Export it all as CSV.

Two ways to validate

Choose how staff verify offers.

Both methods prevent reuse and track every redemption. Pick whichever fits your workflow.

Mark as Used

Button on customer’s phone

  • No hardware or extra devices needed
  • Staff tap the button, confirm, and the status changes right away
  • One walkthrough is usually all the training staff need
  • Best for small teams, single locations

A simple place to start. For many campaigns, this is all you need.

QR code scanning

Staff scans from their own device

  • Uses the phone’s camera in the browser, no app to download
  • Validates and marks used in one scan
  • The scanner decides, so staff don’t make judgment calls
  • Best for multiple locations, high volume

Add scanning when your campaign scales. You can switch without changing your codes. See how QR code coupon redemption works step by step.

Not sure which validation method to use?

Start with Mark as Used, then add scanning when volume grows.

Common questions

Frequently asked

How is this different from printing a coupon code on a flyer?
A printed code is static. Anyone can copy it, share it, or use it multiple times. With Coupon Carrier, every customer gets their own unique code, and once it’s redeemed it’s locked. People can still share it or take a screenshot, but it can’t be redeemed a second time.
Do staff need training?
Barely. For Mark as Used, the entire script is: “If someone shows a coupon, tap the button.” For QR scanning, staff open a web page on their phone and point the camera. One walkthrough is usually enough.
Can I use both validation methods at the same time?
Yes. You can enable both Mark as Used and QR scanning on the same campaign. Some locations might use one method and others the other, or staff can choose based on the situation.
What email platforms do you integrate with?
Mailchimp, Klaviyo, ActiveCampaign, HubSpot, Brevo, and dozens more through Zapier. If you use a hosted signup form, a print batch, or send voucher links yourself, no email platform is needed at all.
How do we get started?
It's self-serve. Create an account, set up your offer, generate or import codes, and start distributing. There's no onboarding call, integration project, or hardware to ship.
