Cello

Cello is referral-program software for companies running partner or user-referral campaigns. It is best suited to teams that need attribution, abuse controls, and reward payments together, with a pricing ladder based on campaign, partner, or referral-revenue scale. The right starting plan depends less on referral volume than on how many campaigns and participants the program must support.

Overview

Cello brings referral links and referral codes into one service, alongside fraud controls and reward payouts through PayPal and Venmo. That combination suits businesses that need to track and reward advocates rather than merely publish a referral offer. Unlimited referrals are included in every listed plan, so the practical constraints are campaign count, transacting-partner count, and—on two plans—referral ARR.

The free tier is useful for proving a small partner program, but its one-campaign and five-transacting-partner limits make it unsuitable for a broad network. Paid tiers provide a clear progression, while enterprise options remove the principal scale limits.

Key features

Referral links and codes provide two attribution methods for campaigns. Fraud controls are important for programs exposed to duplicate, abusive, or otherwise invalid activity. PayPal and Venmo payouts cover two familiar payment routes for rewards, although the available facts do not establish other payout methods.

Unlimited referrals mean referral count itself does not force an upgrade. Instead, Free allows one partner campaign and five transacting partners; Plus raises that to three campaigns and 25 partners; Pro raises it again to 10 campaigns and 100 partners. The stated participant limit is five, which reinforces that the entry level is designed for a very small operating group.

Grow and Scale include all integrations and all features, with referral ARR ceilings of $50K and $100K. Partner Referrals Enterprise offers unlimited partner campaigns and unlimited partners. User Referrals Enterprise offers unlimited referral ARR and custom SLAs, making it the more relevant enterprise route for user-referral economics rather than partner-network capacity.

Pricing

Cello uses monthly billing for its listed plans and has a free option. Free costs nothing and includes unlimited referrals, one partner campaign, and five transacting partners. It fits a small pilot or narrowly scoped program; the campaign and partner caps are the trade-off for zero subscription cost.

Plus costs $80 a month, billed monthly. It includes unlimited referrals, three partner campaigns, and 25 transacting partners. This is the sensible step for a growing but still compact partner operation that has outgrown one campaign.

Pro costs $280 a month, billed monthly, and supports 10 partner campaigns and 100 transacting partners with unlimited referrals. It is aimed at organizations managing several campaigns or a substantially larger partner base; the price increase is justified only when those higher limits are needed.

Grow costs $200 a month, billed monthly, and allows up to $50K referral ARR, unlimited referrals, all integrations, and all features. Its ARR-based ceiling makes it a better fit for revenue-led referral programs than Pro when integration and feature access matter more than a stated partner-count quota.

Scale costs $750 a month, billed monthly, and raises the referral ARR allowance to $100K while retaining unlimited referrals, all integrations, and all features. It is for programs already operating at materially higher referral revenue. Partner Referrals Enterprise has custom pricing and removes campaign and partner limits. User Referrals Enterprise also has custom pricing, removes the referral ARR ceiling, and adds custom SLAs.

Platforms

Cello runs on Android, iOS, and the web, allowing referral-program work across mobile and browser environments.

Who it's for

Choose Cello if your business needs links and codes, fraud controls, and PayPal or Venmo rewards in one referral product, and you can map your operation to campaign or ARR thresholds. Free is appropriate for a small experiment; Plus and Pro suit expanding partner programs; Grow and Scale suit teams whose referral revenue and full integration access drive the buying decision. Enterprise plans are the natural choice when partner or user-referral limits must disappear.

Pros and cons

Pros

Unlimited referrals across the listed plans, so raw referral volume is not the main pricing constraint.

Links, codes, fraud controls, and PayPal or Venmo payouts cover core attribution, protection, and reward needs.

Multiple upgrade paths separate campaign-and-partner growth from referral-ARR growth.

Enterprise tiers remove key scale limits and, for user referrals, add custom SLAs.

Cons

Free is limited to one partner campaign and five transacting partners, restricting it to very small programs.

Plus and Pro still cap campaigns and partners, so larger networks must move to custom-priced enterprise plans.

Grow and Scale impose referral ARR ceilings of $50K and $100K, respectively.

Monthly paid pricing can become significant as a program moves from Plus to Pro, Scale, or enterprise.

Alternatives

Referral Marketing Software is the broader category guide for comparing referral tools.

GrowSurf is a better fit when a free plan with up to 1,000,000 participants and five affiliate programs, plus a 3% success fee and no monthly subscription, is preferable.

ReferralHero suits teams wanting a free-forever tier for up to 25 subscribers with PRO features included, or a 199.00 USD PRO plan.

Referrals.com is worth choosing when a free plan supports one brand and 20 participants per campaign, with a 9.00 USD monthly premium-by-brand option.

InviteReferrals fits buyers seeking a 99.00 USD monthly basic plan with 1,000 new referrers per month and three campaigns.

Mention Me is an alternative for businesses seeking paid, multi-channel referral and advocacy programs.

99minds Referral suits a very small program needing a free tier with 50 transactions and one campaign, then a 49.00 USD monthly basic plan.

AppVirality is aimed at buyers prepared for a paid platform whose Growth plan costs $1,999 a year and includes advanced fraud detection.

SaaSquatch is another paid referral-platform alternative.

Verdict

Cello is a strong choice for teams that want referral attribution, fraud controls, and reward payouts together, with a direct path from a tiny free program to uncapped enterprise tiers. Choose it when your campaign, partner, or referral-ARR requirements fit its plan structure. Look elsewhere if the free tier’s five-partner ceiling is too restrictive or if you prefer pricing based on participant volume, transactions, or a success fee.
