What Are Shopping-to-Stock Apps?
Shopping-to-stock apps reward you with fractional shares of stock when you make purchases at participating retailers. You link your credit/debit card, shop as usual, and receive a small amount of stock—typically $0.10 to $5 worth—based on your spending. Over time, these micro-investments can grow into a meaningful portfolio.
Both Bumped and Bits of Stock operate on this model, but they differ in partner brands, reward rates, and—most importantly for this guide—referral programs. By referring friends, you can earn additional stock bonuses, often with no extra spending required.
💡 Why Referral Value Matters:
- One-time bonus: Many apps pay a flat amount per successful referral.
- Spending requirements: Some require the friend to make a purchase to qualify.
- Caps & limits: Annual referral earnings may be capped.
- Stock vs cash: Referral rewards are usually in stock, which can appreciate.
Bumped Deep Dive: How It Works, Rewards & Referrals
Bumped (now part of SoFi) lets you earn stock when you shop at brands like Nike, Uber, Airbnb, and hundreds of others. You choose your favorite brands, and Bumped gives you up to 10% back in stock on every purchase. The stock is held in a brokerage account with SoFi Invest, and you can eventually sell it.
Bumped Referral Program
Bumped’s referral program is straightforward: for each friend who signs up using your link and makes their first purchase, you both get a $10 stock bonus. There’s no cap on the number of referrals, and the bonus stocks are deposited into your SoFi Invest account.
Bumped Referral Details
$10 per referral📊 Real Example:
Sarah referred 10 friends who each made a purchase. She earned $100 in stock, which she held and later sold for $150 after a market uptick.
Bumped Rewards Structure
- Reward rate: 0.5% to 10% back in stock, depending on brand and offers.
- Brands: Over 300 partners including Nike, Uber, Airbnb, Southwest Airlines, and more.
- Minimum spend: No minimum per transaction, but you must make a purchase to earn.
- Stock allocation: Rewards are fractional shares, typically in popular companies like Apple, Google, or the brand’s own stock.
Bits of Stock Deep Dive: How It Works, Rewards & Referrals
Bits of Stock works similarly: you link a payment method and earn fractional shares when you shop at partner merchants. The platform focuses on small, frequent purchases and pays out in “bits” that accumulate into whole shares.
Bits of Stock Referral Program
Bits of Stock offers a tiered referral bonus. When a friend signs up with your link and makes their first purchase, you both get a $5 stock bonus. If they make three purchases within 30 days, you get an additional $10 stock bonus. So the maximum per referred friend is $15.
Bits of Stock Referral Details
Up to $15 per referral📊 Real Example:
Mike referred 5 friends. All signed up and made first purchases: $25 earned. Three of them completed 3 purchases each, adding $30 more. Total: $55 in stock.
Bits of Stock Rewards Structure
- Reward rate: Typically 1% to 5% back in stock, but varies by merchant.
- Brands: Includes Walmart, Target, Starbucks, Uber, DoorDash, and more.
- Minimum spend: Some merchants require a minimum purchase (e.g., $10) to qualify.
- Stock allocation: Rewards are fractional shares of a diversified portfolio; you can choose to invest in specific stocks or ETFs.

Real Earning Potential: How Much Can You Make?
Let’s run the numbers for different referral scenarios. Assume you refer 10 friends who all qualify for the maximum bonus on each platform.
💰 Scenario A: 10 friends, each makes first purchase only
Bumped: 10 × $10 = $100 stock.
Bits of Stock: 10 × $5 = $50 stock.
💰 Scenario B: 10 friends, each makes 3+ purchases
Bumped: $100 (no tiered bonus).
Bits of Stock: 10 × $15 = $150 stock.
If your friends are active shoppers who will use the app regularly, Bits of Stock can yield 50% more per referral. However, if you have a large network where many only try it once, Bumped’s simpler $10 per referral may be more reliable.
Referral Earnings at 10 Active Friends
Bits of Stock can pay up to 50% more if friends become regular users.
Other Factors Affecting Earnings

- Brand availability: Both apps have extensive partner lists, but Bits of Stock includes more everyday retailers like Walmart and Target, making it easier for friends to qualify.
- App integration: Bumped is integrated with SoFi, so if your friends are already SoFi users, onboarding is seamless.
