The verdict in three sentences
A B2B auto parts marketplace for independent repair shops costs USD 75,000 to 140,000 as an MVP in 2026, with 5 to 7 months of development and a licensed fitment catalogue. The model relies on a 4 to 8% commission per order, which requires around 300 active shops to cover fixed costs. The real risk is not technical: it is signing enough distributors to guarantee 2-hour delivery.
The business model before the code
Two former automotive distribution executives notice that an independent shop in Miami, Hialeah or Doral calls three distributors on average for each part: brake pads, timing kit, alternator. It loses 10 to 15 minutes per part, more than an hour a day for a 4-technician shop. The marketplace promises a single search by plate or VIN, comparison of net prices from 15 distributors and delivery within 2 hours.
A shop's average basket is around USD 195, with 2 to 4 orders per working day. The marketplace charges its commission to the distributor, not the shop, which eases adoption.
| Assumption | Low value | High value | Comment |
|---|---|---|---|
| Average basket | USD 150 | USD 240 | Wear parts and routine mechanics |
| Orders per shop per month | 30 | 70 | Depending on shop size |
| Marketplace commission | 4% | 8% | Paid by the distributor |
| Revenue per shop per month | USD 180 | USD 1,340 | 2026 order of magnitude |
| Monthly fixed costs | USD 38,000 | USD 60,000 | Team, licence, hosting, logistics |
| Active shops at break-even | 250 | 350 | With a median assumption of USD 165 per shop |
| Time to break-even | 18 months | 30 months | Depending on sales pace |
What the MVP costs
The catalogue is the heart of the product. A fitment database (ACES and PIES data in North America, or a TecDoc-type source) maps vehicles to part numbers; its licence is negotiated, often USD 16,000 to 43,000 per year for a platform of this type. Without it, plate or VIN search is unreliable. You also need a plate or VIN decoding service, billed per request.
| Component | Scope | MVP cost (USD) | Annual recurring |
|---|---|---|---|
| Vehicle search and catalogue | Plate, VIN, fitment data, cross-references | 19,000 to 32,000 | Catalogue licence 16,000 to 43,000 |
| Distributor connectors | Net prices and stock from 15 distributors | 16,000 to 38,000 | Maintenance 10% per year |
| Comparison and multi-vendor cart | Sort by price, lead time, brand | 11,000 to 19,000 | Included |
| Payment and split | Shop payment, distributor payouts, commission | 9,000 to 16,000 | 0.5 to 1.5% per transaction |
| 2-hour logistics | Couriers, tracking, proof of delivery | 9,000 to 16,000 | Courier USD 9 to 16 per run |
| Back office and portals | Shop, distributor, admin | 11,000 to 19,000 | Hosting 6,500 to 13,000 |
| MVP total | 75,000 to 140,000 | 38,000 to 75,000 excl. logistics |
The trickiest part is the distributor connector: some expose an API, others send a price file every night. Budget USD 1,100 to 3,200 per distributor depending on format.
Mini case study
Carlos and Mia launch their marketplace with a USD 115,000 MVP and 15 distributors signed across Miami-Dade and Broward. At month 12, 180 shops are active with 40 orders per month at a USD 185 average basket, USD 1,332,000 of monthly volume. At a 6% commission, revenue reaches USD 79,900 per month.
Caution, this calculation assumes dense activity: at 20 orders per shop per month, revenue drops to USD 40,000, below USD 49,000 of fixed costs. Their realistic threshold is therefore around 300 active shops at average frequency. They plan USD 330,000 of funding to cover 18 months, a 2026 order of magnitude.

FAQ
How much does a B2B auto parts marketplace cost?
An MVP costs USD 75,000 to 140,000 in 2026, excluding the catalogue licence. Add USD 38,000 to 75,000 per year for fitment data, hosting and connector maintenance.
Is a fitment data licence essential?
For reliable plate or VIN search, yes in most cases. Without fitment data, the wrong-part rate can exceed 10%, which destroys shop trust.
What commission should we charge?
A 4 to 8% commission paid by the distributor is the norm observed in 2026. Above 8%, distributors prefer to sell directly to their best shops.
How many shops to be profitable?
Plan for around 300 active shops with 30 to 40 orders per month each. In Miami-Dade alone, that represents roughly 10 to 15% of independent shops.
How long does launch take?
The MVP takes 5 to 7 months, including 6 to 8 weeks for distributor connectors. A 2-month pilot with 30 shops comes before the commercial launch.
