FAQs

Voucherify Referral Software

What is referral marketing software?
It helps brands run customer referrals and affiliate-style programs – create referral links/codes, automate rewards, and track performance. Happy customers share, you get qualified new users.
Is there a limit to how many referrals I can run?
No hard cap. Generate, track, and validate at scale, even millions if needed. Self-service plans support up to 100,000 unique referral codes per campaign; enterprise plans offer custom limits.
Can I combine referrals with other campaigns?
Yes. Mix referrals with coupons, discounts, loyalty, or gift cards. For example, use coupons as referral rewards or give loyalty points for successful invites.
Does Voucherify offer referral templates or widgets?
We don’t ship fixed widgets. Instead, you get APIs, SDKs, and samples to build an on-brand referral UI that fits your stack.
Do you support double-sided referral rewards?
Yep. Reward both the advocate and the friend, e.g., advocate gets store credit or points; friend gets a coupon on first purchase. Rules and amounts are fully configurable.
How are referral rewards delivered and tracked?
Issue coupons, gift cards, points, or store credit automatically once conditions are met. Everything is recorded with statuses and metadata so you can audit and optimize.

How does Voucherify prevent referral fraud?
Use unique links/codes, device/email checks, per-customer limits, velocity and budget caps, and custom rules to flag self-referrals and duplicates. Integrate with analytics/fraud tools for real-time monitoring
