Referral cards for business: what to print, what to write, how to track them
A referral card is a printed card a happy customer hands to someone else, carrying an offer for both sides. It still works where the ask happens face to face — trades, salons, clinics, gyms. What decides whether the print run pays for itself is the wording, the offer structure and whether you can track redemptions.
- A referral card is for businesses whose best moments happen face to face — print for the moment, not the mailbox.
- Lead the card with the friend's reward; the referrer's side goes second, in smaller type.
- Design to Vistaprint's published specs — 3.5"×2" trim, 3.61"×2.11" bleed, 3.36"×1.86" safe area — and the run will not need reprinting.
- Per-customer codes or QR links are what turn a stack of cards into a measurable channel.
- The card is only half the mechanism; the logged redemption and the thank-you to the referrer are the other half.
Do referral cards still work?
For businesses whose best moments happen in person, yes. An HVAC tech standing in a kitchen that finally cools, a colourist at the mirror reveal — that is the referral moment, and a card is the only referral mechanism that fits in it. Nielsen has measured recommendations from people we know as the most trusted form of advertising for over a decade; the card just gives the recommendation something to travel on.
Where cards do not work: businesses that never meet their customers. If your product is software and your customer relationship lives in email, the referral link belongs in the product and the inbox, not in an envelope.
What should a referral card actually say?
Three things, in this order: what the new customer gets, what the referrer gets, and how to claim it — a code or QR plus a phone number. Write it in the voice you use in person. The examples below are ready to adapt; every one leads with the friend's side of the deal.
This card is worth $50. If [customer name] gave it to you, they think we're worth calling — that means a lot. $50 off your first service call; they get $50 off their next tune-up once yours is done. [Company] · [phone] · code on the back
Bring this card, meet [stylist name]. 20% off your first appointment — and the friend who handed you this gets 20% off their next colour. We'll know who to thank from the code below. [Salon name] · [address] · [booking link or phone]
A recommendation from a patient is the nicest review we get. New patients with this card: [offer — e.g. $50 off your first visit, or whitening with your first exam]. And we'll say a proper thank-you to whoever gave it to you. [Practice name] · [phone] · quote code [___] when booking
Most of my work comes from people like you. If someone you know is buying or selling, hand them this card — I'll take care of them the way I took care of you, and there's a [gift — e.g. $100 gift card] with your name on it at closing. [Agent name] · [phone] · [email]
Workouts are better with an accomplice. This card gets a friend their first week free. If they join, next month's membership is on us — that's our thank-you to you. [Gym name] · scan the code to claim · [address]
Which print specs avoid a reprint?
Design at business-card size unless you have a reason not to: 3.5 by 2 inches, with artwork extended to a 3.61 by 2.11 inch bleed and everything that matters kept inside the 3.36 by 1.86 inch safe area — 1050 by 600 pixels at print resolution. Those are Vistaprint's published specs, and most reprints happen because a border or a code sat outside the safe area.
- Trim size 3.5" × 2" — it fits wallets, card holders and till counters
- Bleed 3.61" × 2.11": background colour and imagery must reach this line
- Safe area 3.36" × 1.86": keep text, codes and logos inside it
- 1050 × 600 px artwork at print resolution; heavier stock reads as a more valuable card
- Put the offer on the front and the code, terms and expiry on the back
Should the offer be one-sided or two-sided?
Two-sided, almost always. The card's carrier has to make a small social claim on a friend's attention, and "you get $50" is a far easier sentence to say than "I get $50 if you call these people". Fund the friend's side more generously than the referrer's if the budget forces a choice.
Match the reward's form to the relationship. Service trades do well with dollar amounts off real invoices; appointment businesses do better with percentage or add-on offers that fill the calendar; membership businesses can give time. What matters is that both sides can be honoured without a manager's discretion — a card that gets argued about at the till costs more than the discount.
How do you track a paper card?
Give every customer their own code — printed, written on the card, or carried in a QR that opens their personal referral link. When the new customer redeems, the code tells you whom to thank and pay. Without per-customer codes you can count redemptions but never attribute them, and the referrer side of the offer silently breaks.
- Per-customer code on each card — a batch of generic cards can be counted, not attributed
- QR to the customer's personal referral link, so the same code works online and in person
- A write-in "referred by ______" line as the fallback when someone loses the card but remembers the person
- Log redemptions the day they happen; the thank-you to the referrer is half the mechanism
- Watch for stacks redeemed by one person — cards left on counters produce redemptions with no relationship behind them
What wastes a print run?
Five repeat offenders: no expiry date, an offer that needs a manager to interpret, a reward only the business cares about, no way to attribute the card to a customer, and handing cards out at random instead of at the moment someone is visibly delighted. All five are fixable before the file goes to print.
What size should a referral card be?
Standard business-card size: 3.5 by 2 inches, designed with a 3.61 by 2.11 inch bleed and all text inside the 3.36 by 1.86 inch safe area. It is the size that survives in wallets, which is where a referral card needs to live.
How do you track paper referral cards?
Print or write a unique code per customer, or use a QR that opens that customer's personal referral link. The redemption then attributes itself. A generic batch code tells you the cards worked but never who to thank.
What should a referral card offer?
Something for both sides, with the new customer's side stated first and funded at least as generously. Dollar amounts suit trades and invoices; percentages and add-ons suit appointments; free time suits memberships.
