Step 1: Define Your Referral System Goals

Before setting up, you must determine:

✔ What are you offering? (e.g., discount, cashback, free credits, perks)
✔ Who gets the reward? (Referrer, new user, or both?)
✔ How will you track referrals? (Unique codes, referral links, or both?)
✔ Which tools will manage referrals? (Airtable, Zapier, Google Sheets, etc.)

A crystal-clear structure will ensure your system runs smoothly and is scalable from day one.
