Consumer to Business

Consumer to business (C2B) is a model where individuals sell products, services, data, or attention to firms. It reverses the retail flow: the person is the supplier and the company is the buyer, paying per project, per post, or per survey response.

The model gained traction in the late 1990s alongside the first freelance marketplaces and reverse-auction sites. It has scaled sharply since 2020, as remote work, creator platforms, and paid data panels turned everyday consumers into micro-suppliers.

C2B sits alongside B2B, B2C, and C2C — the four core commerce archetypes. Most large platforms blend C2B mechanics with marketplace software, so a buyer can source labour, media, or intent data at scale.

Key takeaways

• Consumer to business (C2B) reverses the usual sale: the individual supplies, the company buys.
• Common flows include reverse auctions, freelance marketplaces, influencer licensing, affiliate programs, device trade ins, and paid consumer data.
• MBO Partners counted 72.1 million U.S. independent workers in 2024, the talent pool feeding C2B labour platforms.
• Pricing is set by the consumer in a reverse auction or agreed per project on a freelance deal, not fixed by the seller.
• Outsourcing firms use C2B channels to source specialist talent, moderation crowds, and market research panels.

How it works

A C2B transaction starts when a consumer publishes an offer on a platform businesses can search: a rate card, a resume, a listing, a name your price bid, or usable content. The company reviews it and agrees terms.

Payment then goes to the individual directly or into the platform’s escrow account, released on a trigger. That trigger is usually a milestone, a published post, a confirmed sale, or a submitted survey response.

Most C2B platforms fall into one of six structural patterns. Each carries its own discovery mechanism, payment model, and quality control layer, as set out below.

The underlying workflow rarely changes: discovery, agreement, delivery, escrow release.

Platforms compete on the trust layer instead: identity verification, ratings, dispute resolution, and payment protection — the customer experience (CX) side of a marketplace.

Those are the same buyer priorities Zendesk’s CX Trends report flags. The trust layer is what lets a Fortune 500 buyer commission a $500 logo from a stranger in Karachi with no purchase order.

Contact centres and business process outsourcing (BPO) providers touch C2B twice over. First, they run the support queues for the platforms themselves, often a Manila or Cebu team fielding marketplace disputes.

Those queues follow the service patterns Gartner tracks across the sector, staffed by the roles the U.S. Bureau of Labor Statistics counts under customer service occupations.

Second, providers source specialist talent through C2B channels when a client needs a linguist, a niche developer, or a moderation contractor faster than a traditional hire allows.

Pricing is the tell. In a reverse auction the consumer names the number, in a freelance deal both sides agree a rate per project, and in an affiliate program the buyer sets a fixed cut the supplier takes or ignores.

Examples

C2B turns up wherever a company buys from an individual at scale. The clearest cases sit in travel bidding, freelance marketplaces, creator sponsorships, device trade in schemes, and paid research panels, each with its own pricing logic.

Priceline pioneered mainstream C2B in 1998 with Name Your Own Price hotel and airfare bidding. The mechanic is a textbook reverse auction: the consumer sets the price, the supplier accepts or rejects it.

Upwork, formed from the 2013 Elance-oDesk merger, reported $770.7 million in 2024 revenue against marketplace gross services volume above $4 billion. More than 18 million registered freelancers bid on projects posted by firms from Airbnb to Microsoft.

Fiverr, based in Tel Aviv and listed on the NYSE, posted $391 million in 2024 revenue with roughly 3.8 million active buyers. Sellers advertise packaged gigs from $5 — a productised C2B service catalogue.

YouTube’s BrandConnect marketplace lets creators pitch sponsorship packages straight to advertisers, with payment tied to a published post or a cost per thousand views.

A 2024 Influencer Marketing Hub survey put global influencer marketing spend at $24 billion, most of it moving through licensing deals between individual creators and brand buyers.

Trade in programmes are the quiet C2B channel. Apple Trade In asks an owner to grade an old iPhone online, quotes a credit against a new purchase, then takes the handset for resale or recycling.

User research firm dscout pays panellists $25 to $100 per completed diary study, then packages the responses for enterprise teams. The product here is the consumer’s own attention and opinion — priced per response.

FAQ

What is an example of a C2B transaction?

A photographer licensing a stock image to Getty Images, a freelancer taking a $300 copywriting job on Upwork, or a shopper winning a hotel room on Priceline at a self nominated price. Each has an individual supplying and a company buying.

How is C2B different from C2C?

C2B puts a company on the buying side: Upwork clients, brand advertisers, research firms. C2C keeps both sides as individuals, as on eBay, Vinted, or Facebook Marketplace, with the platform taking a listing or transaction fee.

Why do businesses buy from consumers?

Speed, cost, and access to specialist skills. A C2B marketplace opens a global talent pool without the fixed cost of hiring, and pricing is set by the buyer or agreed per project rather than dictated by the seller.

Is influencer marketing a C2B model?

Yes. The creator sells reach, a licensed post, or an endorsement, so the individual is the supplier and the brand is the buyer. Payment usually lands per post, per view, or per conversion.

What role does outsourcing play in C2B?

BPO providers run the support, moderation, and dispute queues for most large C2B platforms, and buyers use those same marketplaces to source niche talent such as linguists, developers, and annotators without a full time hire.
