You are picking a referral program software plan ahead of a social push, and the pricing pages look comparable at a glance. They are not. Every vendor prints the word “referral,” and no two bill for the same event. Size a plan by the traffic a giveaway should produce and you are guessing at a unit you have not identified yet.
Why “tracked referral” is the wrong question to ask a vendor
Estimating referral volume and finding the tier that covers it works only if “referral” is one countable thing. Across these three vendors it is three different things.
ReferralCandy has no referral-count cap anywhere in its plan structure, and no click or share counter either. It charges a fixed monthly fee plus a success fee calculated as a percentage of revenue from converted orders. Referral Rock takes the opposite approach and says so explicitly: referrals are unlimited, with no caps and no overage fees at any volume. What it meters instead is a unit it calls “members.” GrowSurf prices on “participants,” and puts the billing trigger earlier than either. Someone becomes a participant on receiving a unique referral link, and links are generated when a logged-in user visits the referral portal. No conversion required. Intent to share is enough.
That lands on the moment you are planning for. A social giveaway is a traffic event first: it produces visits, entries, and shares, and may or may not produce sales in the same month. A plan chosen on expected traffic is priced right under one of these models and wrong under another, depending on the noun in the vendor’s fine print.
ReferralCandy: no referral cap, a percentage of what converts
ReferralCandy publishes four plans, each pairing a flat monthly fee with a success fee percentage that falls as the base fee rises. Basic is $39 per month plus a 10.5% success fee. Grow is $79 plus 3.5%. Scale is $249 plus 1.5%. Enterprise is $799 plus 0.25%. All features are on every plan, so the tier choice is a pricing decision, not a feature decision.
The success fee is where the definition lives. ReferralCandy’s pricing FAQ explains that the fee is a percentage of the purchase subtotal, after discounts and before taxes and shipping, paid only on net-new customers the program brings in. It applies to each new customer’s first three orders only. Repeat orders after that carry no success fee, and the FAQ states there is never a fee on the reward paid to the advocate.
Read that against a giveaway producing shares and clicks and no completed orders. It costs nothing beyond the base fee, because no unit in the pricing can be incremented by a share or a click. The exposure is not volume. It is conversion, from new customers only.
ReferralCandy’s own math: the same revenue, two different bills
The vendor publishes its own worked example, worth reproducing because it is theirs rather than a constructed case. It imagines $12,000 in referred new-customer revenue in June, run through two tiers.
| Plan | Base fee | Success fee on $12,000 | Month total |
|---|---|---|---|
| Grow | $79 | 3.5%, or $420 | $499 |
| Scale | $249 | 1.5%, or $180 | $429 |
The higher tier produces the smaller bill on identical revenue, which is the point ReferralCandy is making with it. Nothing there counts referrals, shares, or clicks: only converted revenue and the bracket you sit in.
Referral Rock: unlimited referrals, a member cap underneath
Referral Rock defines its terms on the pricing page itself, which makes the terms the story. Four things matter here:
- Its definition of a referral. The FAQ states: “A referral is when a member shares your program and someone takes action, such as signing up, making a purchase, or completing a form.” The billable event requires a completed action at the far end.
- The plan and the unlimited claim. The Operator Plan is $250 per month. Asked “Are referrals really unlimited?”, the FAQ answers yes, with no referral caps or overage fees, and says the price stays $250 a month at any referral volume.
- The unit that is actually metered. The plan includes 10,000 base members, which the FAQ describes as covering everyone you bring in yourself through manual imports, CSV uploads, and one-off additions. On top of that sit up to 1,000 rolling members you can add free each month through a connected source such as your checkout or your forms. That allowance resets monthly, does not roll over, and does not draw from the base members. Additional blocks of 10,000 base members are an add-on at $125 per month.
- What that means for a giveaway. The shares and resulting signups fall into the unlimited referral bucket and cost nothing extra. But if the campaign also adds more than 1,000 new members in one month through a connected source, the pressure lands on the member allowance, a separate line from referral volume.
GrowSurf: a portal visit already counts
GrowSurf is the vendor here where generating a shareable link, with no conversion behind it, is already billable. Its pricing FAQ defines the unit directly: “A participant is anyone who either receives a unique referral link (referrer) or signs up through one (referred). We count participants based on unique email addresses.” The same answer adds that referral links are generated in real time only when a logged-in user visits your referral portal, signaling intent to share.
GrowSurf supplies its own illustration of the scale. Its FAQ describes a program with 10,000 users where an announcement goes out, and states that around 20%, or 2,000 users, might show interest in participating. Those users would visit the portal and become participants, each receiving a unique link, and anyone signing up through those links is added as a participant too. The FAQ is explicit that an entire user base does not count, only those who engage. Still, in that scenario 2,000 billable participants exist before one has referred anybody.
On overage, the same FAQ states that exceeding the participant limit automatically upgrades you to the next tier, prorated, so an account scales up rather than being blocked or charged a penalty. That is a different failure mode from a hard cap. One caveat: GrowSurf’s tier prices render through a client-side calculator and the fetched page returns placeholders, so no dollar amount for any tier is stated here.

What to check on a vendor’s own pricing page before setting a plan by expected traffic
Before picking a tier, answer four questions from the vendor’s own pages:
- Find the literal definition of the billed noun. Referral, participant, member, order, conversion. It is usually in the pricing page FAQ. Take it from the vendor, not a third-party roundup, which flattens the distinction you need.
- Establish where the count starts. Does the meter increment on a click or a portal visit, as GrowSurf’s definition does, or only on a completed action such as a signup or purchase, as Referral Rock’s does? That separates traffic risk from conversion risk.
- Find the overage behaviour. Three patterns appear here: no cap paired with a revenue percentage, an uncapped unit beside a capped one, and an automatic prorated upgrade. Each is a different surprise on the invoice.
- Size the campaign as a traffic event first. Estimate visits and shares separately from expected sales, then run both against the vendor’s unit. The gap between those figures is what varies across vendors.
Read the meter before you pick the plan
The same pattern runs across adjacent tooling, where the vendor’s unit rarely matches what the buyer counts. This blog has covered response-metered lead capture tools, what happens when a tracking tool’s cap is exceeded, and what the meter actually counts in link management pricing. For the vendors above, open their pricing pages and read the FAQ rather than the plan cards. In all three, the definition that governs your bill sits below the fold.

FAQ
Does referral software charge per referral or per completed sale?
It depends entirely on the vendor. ReferralCandy charges a percentage of revenue from converted new-customer orders and has no referral-count cap. Referral Rock separates unlimited referrals, defined as a member sharing your program and someone taking action, from a capped count of members. GrowSurf counts a participant the moment someone visits the portal and receives a link, before any sale. Asking how many referrals a plan includes only means something once you know which of those the vendor means.
Can a social giveaway push me over my referral software plan without any completed sales?
On GrowSurf, yes. Visiting the portal to get a share link already makes someone a participant, so traffic alone moves the meter, and exceeding the limit triggers an automatic prorated upgrade. On ReferralCandy, no, because the fee is a percentage of converted revenue and the plans carry no referral or traffic cap. On Referral Rock, referrals are unlimited at any volume, but a giveaway adding more than 1,000 new members in a month through a connected source would exceed the free rolling member allowance, billed separately.
