Start
Know the outcome.
Run a 60-day referral test with a clear qualifying event, a reward the math supports, written terms, working attribution, and a human review.
Audience, time, and cost
Businesses with happy repeat customers and capacity to spare, not owners hoping a reward will paper over inconsistent delivery.
Time and costSetup takes several hours. Cap the test’s reward budget and count reward cost inside your job economics.
Before you start
Know your customer acquisition cost, service margin, capacity, existing discounts, and the exact event that proves a referral became a real customer.
Tools and materials
- referral code or source field
- reward ledger
- program terms
- invitation copy
- fraud and dispute rules
Steps
Do the work in order.
-
Step 1 Set the program objective
Pick one goal: new first jobs, a specific underused service, or partner introductions. Don’t mash unrelated objectives together.
-
Step 2 Define qualification
Write down who counts as new, which services qualify, any minimum completed purchase, payment status, the attribution window, and how cancellations, refunds, and duplicate claims play out.
-
Step 3 Choose a sustainable reward
Model the reward against discounts, direct cost, normal margin, and fraud loss. Favor a simple credit or fixed benefit that doesn’t force work nobody needs.
-
Step 4 Write plain terms and disclosure
Spell out the steps, timing, limits, how rewards arrive, expiration where it’s lawful, privacy, changes, who to contact in a dispute, and the disclosure expectation.
-
Step 5 Build traceable attribution
Use a code or link plus a “Who referred you?” field. Keep the first piece of evidence and set a manual rule for conflicts.
-
Step 6 Invite appropriate customers
Ask after a great result or a good follow-up. Never chain the invite to a positive public review, and never send without allowed consent.
-
Step 7 Run and review the test
For 60 days, track invites, referred leads, completed jobs, reward cost, margin, disputes, repeat visits, and fraud before you expand anything.
Reference
Use the detail when you need it.
How it works
A referral program pays for an introduction only after a defined, legitimate outcome. Keep it simple enough to explain in one paragraph and controlled enough to block self-referrals, duplicate credit, margin erosion, and rewards that expire on people by surprise.
Terms used in this guide
- Qualified referralA new, eligible customer who completes the program’s stated event, like a paid first job.
- Attribution windowThe stated stretch of time in which an introduction can still earn referral credit.
Common mistakes
- Paying for raw contact lists.
- Letting rewards stack with unlimited discounts.
- Changing the terms after a referral happens.
- Bundling a referral ask with a five-star review ask.
- Paying out with no documented qualification.
Troubleshooting
- Two customers claim the same referralApply your written evidence-and-timing rule the same way every time, and document any goodwill exception separately.
- Rewards are eating the marginAdjust qualification, the reward, service eligibility, or stacking rules instead of hoping upsells cover it.
- Plenty of referrals, mostly bad fitsHand referrers a one-sentence picture of your ideal customer, and qualify referred leads like any others.
Finish
Check the result and close the loop.
What good looks like
- The rules fit in one paragraph.
- Rewards follow completed, eligible work.
- You can audit every attribution.
- Material rewards are easy to disclose.
- The referred friend gets normal honest pricing and care.
- Fraud gets reviewed without accusing customers.
Final checklist
- Objective and qualified event set
- Economics modeled
- Terms reviewed
- Attribution tested
- Reward ledger running
- Invites kept separate from reviews
- 60-day review scheduled
What to do next
- Build outreach for specific partners.
- Watch how long referred customers stick.
- Refresh the terms before any change.

Should both people receive a reward?
It can work if the combined cost holds up and the terms are clear. Model both sides before you launch.
When should the reward be issued?
After the disclosed qualifying event and any payment or refund condition clears, not the moment someone submits contact info.
Can I combine referrals and reviews?
Keep them separate. A referral reward should never hinge on a positive review or be used to nudge review sentiment.
