There are three main thrift store business models: donation-based, buy-outright resale, and consignment. Each one sources inventory differently, requires different staffing, and produces different profit margins — so the right fit depends on your budget, available labor, and mission.
Here’s a quick overview:
This blog breaks down the startup costs of each model, how to staff it, where inventory sourcing gets complicated, what margins to realistically expect, and how to pick the right model for your goals.
Along the way, we’ll point out where ThriftCart’s point of sale (POS) features support each model — since donation-based, buy-outright, and consignment shops each rely on different tools day to day.
Here’s how donation-based, buy-outright resale, and consignment thrift store business models compare.
Quick take: Free inventory, high gross margins, but labor-intensive sorting and volunteer management
Donation-based thrift stores collect donated goods from the community, sort them, and sell what’s usable, with proceeds typically funding a nonprofit’s programs. Goodwill, The Salvation Army, and most local charity shops run this way.
Pricing is based on brand, condition, demand, and store strategy, often with volunteer help. Inventory replenishes continuously through donations, and stores track sales data to spot what’s moving and clear what isn’t.

$5,000–$30,000 |
This is where the donation model diverges hardest from the other two.
Many nonprofit thrift stores run primarily on volunteer labor, but the IRS’s “substantially all” rule matters here — a thrift store can be exempt from unrelated business income tax on its sales only if roughly 85% or more of the labor hours are unpaid.
In practice, most thrift stores pair a small paid core team (store manager, donation coordinator, and sales associates) with a volunteer coordinator role and a rotating volunteer bench for sorting, pricing, and floor support.
Sourcing is the simplest of the three models operationally, but the most labor-intensive per item.
Donations arrive unsorted and unpriced, so someone has to inspect, sort, price, and reject unsellable items continuously. Donation drives, dropoff kiosks, and community partnerships all feed the pipeline, but the sorting bottleneck is usually what limits how fast inventory hits the floor.
This is the model’s biggest financial advantage.
Because cost of goods sold (COGS) is at or near zero, gross margins run 50–70% — well above the 30–50% typical of resale or consignment.
Net margins after rent, payroll, and overhead are more modest, typically landing in the 5–15% range for well-managed stores (with some sources reporting as low as 3% for smaller operations and up to 30% for efficient urban locations).

Quick take: Highest margin ceiling of the three, but requires cash on hand and skilled buyers
Resale stores acquire inventory by purchasing it from individuals, wholesalers, or liquidators rather than accepting donations.
An example of this business model is Plato’s Closet or Buffalo Exchange. A customer brings in items, staff evaluate them on the spot, and the seller gets cash or store credit immediately.
Items are inspected, cleaned, and prepared for sale, with prices set against brand, condition, demand, and comparable market prices.

$20,000–$150,000+ |

Branded franchise (e.g., Plato’s Closet) |
$287,000–$417,000 |
The franchise figure reflects a franchise fee and brand-mandated store size. An independent concept can launch for a fraction of that, with the budget going toward buying power rather than sorting infrastructure.
This model runs almost entirely on paid staff, not volunteers.
Buying inventory requires trained judgment calls — condition grading, brand and trend authentication, and pricing negotiation at the buy counter — which is a paid, skilled role rather than something you hand to rotating volunteers.
Retail labor turnover at the buy counter is a commonly cited operational risk in this model, since it’s more customer-facing and negotiation-heavy than a donation intake desk.
Sourcing is the most complex of the three models to manage well, because every item is a small buy decision with cash risk.
Payout is typically 20–40% of the item’s intended resale value, depending on the source — buy-outright chains like Plato’s Closet and Buffalo Exchange commonly pay around 30–40% of resale price.
Liquidation pallets are another common source, but they carry their own risk (often costing $300–$2,000 per pallet with no guarantee of condition or sellability). Getting the buy price wrong in either direction — overpaying erodes margin, while underpaying drives sellers elsewhere — is the biggest way operators lose money in this model.
Done well, this is the highest-margin model of the three.
Plato’s Closet’s own franchise disclosure reports an average 63.7% gross margin across its stores, but that margin is fragile. Misapplying donation-based thrift store pricing logic to a buy-outright model (such as charging thrift-store prices on inventory you paid cash for) is a commonly cited way operators erode 30–40% of their gross profit.
Quick take: Lowest startup cost of the three, but the most administratively heavy to run day-to-day
Consignment stores sell items on behalf of their original owners (consignors) and take a commission when something sells. The consignor gets paid only after the item sells, letting individuals offload unwanted goods without the hassle of listing them online, and letting the store build inventory without paying for it upfront.

Consignment leans toward a small, paid, detail-oriented staff rather than a volunteer bench.
The work is administratively heavy — tracking who owns what, calculating payouts, and processing consignor statements — which doesn’t distribute well across rotating volunteers the way donation sorting does.
Customer service also skews toward relationship management, since consignors are effectively vendors you need to keep happy and coming back with better inventory.
Sourcing is a negotiation and relationship business.
As you set up consignor agreements, you’re deciding the commission split, how long items sit before being returned or marked down, and how picky you’ll be about what you accept.
Commission rates typically run 25–60% of the sale price, with 40% cited as a common industry average. General everyday consignment often falls at the lower end (15–25%), while designer or luxury consignment commands the higher end (40–60%) because of the added authentication and marketing work involved.
Gross margins after consignor payouts typically land in the 30–50% range before fixed costs like rent, staff, and marketing are factored in, so net margins depend on overhead discipline.
As a reference point, an online consignment operation selling roughly 10 items a week at a $300 average price and a 50/50 split can net around a 40% margin after marketing costs.

There’s no universal “best” model, but here’s an easy way to think about it:
Whatever model you land on, the POS system underneath it should flex to match.
ThriftCart is built to support all three: donation tracking and volunteer permissions for donation-based stores, SKU-level inventory and fast payouts for buy-outright resale, and reporting and bookkeeping integrations for consignment shops keeping close tabs on payouts.
