A Loyalty Program for DoorDash & Grubhub Orders
DoorDash and Grubhub can bring in steady volume without building a reusable customer list. That is the core problem: the order belongs to the marketplace, not the restaurant, so the relationship usually ends when the delivery does.
The missing piece
This is the same structural gap you see with other marketplaces. The restaurant gets the order details needed to cook and deliver, but not a durable way to reach that customer again on its own.
That means a "regular" on DoorDash or Grubhub can still look like a first-time customer every time.
The bag is the channel you still own
The one part of the transaction the restaurant fully controls is the bag itself. A small printed card with a QR code turns that moment into a direct path back to the restaurant, without needing the marketplace's help.
If the code is in the bag, the restaurant owns the touchpoint.
How it works
Ruffus generates single-use QR codes that merchants print in batches and drop into delivery or takeout orders. A customer scans the code on their own phone and immediately lands on that restaurant's loyalty card.
There is no app to download and no account required to start. The card can open in Apple Wallet, Google Wallet, or the browser, depending on the flow the restaurant uses.
Why single-use matters
A reusable QR code can be copied, shared, or screenshotted. Single-use codes close that loophole because each printed code can only be redeemed once.
That keeps the math honest and prevents one code from being spread across orders the restaurant never served — the same discipline a paper punch card never had.
No POS integration needed
Because the code is printed and the customer scans it themselves, the restaurant does not need a terminal, reader, or marketplace integration. It works the same way whether the order came from DoorDash, Grubhub, or takeout.
A restaurant can print a batch before dinner service and start using it the same night.
What the restaurant gets
Once the first scan happens, the restaurant has a direct relationship it can actually use. It can send stamps, bring the customer back with a follow-up, or simply keep the card available for the next order.
That is the real point of the bag insert: turning an anonymous delivery into someone the restaurant can reach again.
Short version
DoorDash and Grubhub give restaurants the order, not the customer. A single-use QR code in the bag changes that by creating a direct loyalty touchpoint the restaurant controls.
