B2B trading, short for business-to-business trading, is the buying and selling of goods or services between companies rather than to individual consumers. A manufacturer sells components to an assembler, a wholesaler sells pallets of stock to a retailer, a distributor supplies a restaurant group. The products may look similar to consumer goods, but the deals work differently: orders are larger, relationships last longer, contracts matter, and payment is rarely handled with a simple card swipe.
This guide walks through how a typical wholesale deal unfolds, from the first enquiry to after-sales follow-up, and highlights where buyers and sellers most often run into trouble. It is general information. Tax, customs and contract rules vary by country and by product, so check official guidance or a qualified adviser for your own situation.
What makes B2B different from B2C
Several features set business trading apart:
- Larger, less frequent purchases. A single order can represent a significant share of a company’s monthly spend or revenue.
- Multiple decision-makers. Purchasing, finance, operations and sometimes legal all have a say.
- Negotiated terms. Prices, minimum quantities, delivery schedules and payment terms are often negotiable rather than fixed.
- Longer relationships. Repeat business and reliability matter more than a one-off bargain.
- More documentation. Quotes, purchase orders, contracts, invoices, packing lists and certificates form the paper trail.
- Rational, specification-driven buying. Buyers compare specifications, total cost and risk, not just appeal.
Understanding these differences helps you set expectations. A buyer who treats a supplier like an online shop will be surprised by lead times and contracts; a seller who treats a buyer like a casual customer may lose trust.
The main players in a wholesale deal
| Role | What they do |
|---|---|
| Manufacturer or producer | Makes the goods |
| Distributor or wholesaler | Buys in bulk and resells to retailers or other businesses |
| Trading company or agent | Connects buyers and sellers, sometimes taking title to goods, sometimes earning a commission |
| Retailer or end-user business | Buys to resell or to use in operations |
| Logistics providers | Freight forwarders, carriers, customs brokers and warehouses |
| Financial providers | Banks and finance firms that offer payment instruments, credit or insurance |
A trading company in the middle can add value by sourcing, consolidating shipments, handling documentation and managing quality checks. It can also add cost and distance, so buyers should understand exactly what they are paying for.
Step-by-step: how a wholesale deal works
1. Identify the need and the specification
The buyer defines what is needed: product type, specification, quantity, quality standard, packaging, delivery window and target price range. Clear written specifications prevent most later disputes. Include tolerances, materials, certifications and any labelling requirements.
2. Find and shortlist suppliers
Buyers source through referrals, trade shows, industry directories, online marketplaces and direct outreach. A shortlist of three to five candidates is usually enough to compare. Our guide on how to find and vet a reliable supplier covers due diligence in detail.
3. Request quotes
A request for quotation, or RFQ, asks suppliers to propose a price and terms for the same specification. Giving every supplier the same information makes quotes comparable. Ask for unit price, minimum order quantity, lead time, validity period of the quote, payment terms, and the trade term for delivery.
4. Evaluate samples
For physical goods, samples reduce risk. Test them against your specification, and keep records. Be clear whether samples are free, paid or credited against a later order, and who pays shipping.
5. Negotiate
Price is only one element. You can also negotiate quantity breaks, delivery schedules, packaging, payment terms, warranty conditions and exclusivity. Aim for an agreement both sides can live with, since a supplier squeezed too hard may cut corners. See our guide to negotiating payment terms with suppliers for tactics.
6. Agree the contract or purchase order
For a first deal, a written agreement or at least a detailed purchase order is essential. It should confirm products, quantities, prices, currency, delivery terms, payment terms, inspection and acceptance, remedies for defects or delay, and governing law. See how to write a purchase order for the elements to include.
7. Arrange payment
Common methods include bank transfer, open account (pay after delivery on credit terms), advance payment, letters of credit and documentary collection. Each shifts risk differently between buyer and seller. New relationships often start with more security (such as a deposit or a letter of credit) and move toward open account as trust builds.
8. Production and quality control
If goods are made to order, the supplier produces them to specification. Buyers often arrange inspections before shipment, either with their own staff or with an independent inspection company. Agree in advance what happens if the goods fail inspection.
9. Shipping and customs
Goods move under agreed trade terms, such as the Incoterms rules published by the International Chamber of Commerce, which define who handles transport, who pays for what, and where risk transfers. Our article on Incoterms explained in plain English shows how to read them. For cross-border trade, someone must also handle export and import clearance, duties and taxes.
10. Receiving and inspecting
On arrival, check quantities and condition against the paperwork, record any damage promptly, and notify the supplier and carrier within the time limits in your contract or the carrier’s terms.
11. Invoicing and payment
The supplier issues an invoice that matches the purchase order. The buyer pays according to the agreed terms. Mismatched invoices are a common cause of delay, so check details carefully.
12. After-sales and review
Review the deal: quality, timing, communication and total cost. Share feedback with the supplier, resolve any claims, and decide whether to reorder or look at alternatives.
Key terms you will meet
- MOQ (minimum order quantity): the smallest order a supplier will accept.
- Lead time: the time between order and delivery.
- Net 30 / Net 60: payment due 30 or 60 days after the invoice date.
- Proforma invoice: a preliminary invoice used to agree on details or request an advance payment.
- Bill of lading: a transport document for sea freight that acts as a receipt and evidence of the contract of carriage.
- HS code: a standardised numerical code used internationally to classify traded products for customs.
- Landed cost: the total cost of getting goods to your door, including freight, duties, taxes and handling.
- Incoterms: standard trade terms that allocate responsibilities and risk between buyer and seller.
Understanding the real cost of a deal
The unit price on a quote is rarely the true cost. Build a simple landed-cost sheet for each option:
- Unit price × quantity
- Packaging and inspection costs
- Freight and insurance
- Customs duties and import taxes
- Port, handling and local delivery charges
- Cost of money, meaning the financing cost of paying early or holding stock
- Allowance for defects, delays and returns
A slightly more expensive supplier with shorter lead times and fewer defects can easily be cheaper overall.
Choosing between buying direct and buying through an intermediary
A question that comes up early is whether to buy straight from the manufacturer or through a distributor, wholesaler or trading company. There is no universal answer, but the trade-offs are fairly predictable.
Buying direct usually means a lower unit price and more control over specifications, but higher minimum order quantities, longer lead times, and more work on your side: shipping, customs, payment risk and quality checks. It tends to suit buyers with enough volume to justify the effort and the staff to manage it.
Buying through an intermediary typically means smaller minimums, quicker delivery from stock, local invoicing and one point of contact for problems. The price per unit is usually higher because the intermediary carries inventory and risk. This route often suits smaller buyers, businesses testing a new product line, and anyone who values convenience over the last few percentage points of margin.
A practical approach is to start with an intermediary while you learn the product and the market, then move volume direct once demand is proven and you can describe exactly what you need. Whichever route you choose, keep the same discipline: written specifications, agreed terms and records of every step.
Managing risk
Common risks in B2B trading and ways to reduce them:
| Risk | Mitigation |
|---|---|
| Supplier fails to deliver | Vet the supplier, start with smaller orders, use staged payments or secure instruments |
| Quality does not match | Written specifications, pre-shipment inspection, clear acceptance criteria |
| Payment default | Credit checks, deposits, credit insurance, clear payment terms |
| Currency movements | Quote in a stable currency or consider hedging tools discussed with your bank |
| Transport damage or loss | Appropriate insurance, good packaging, careful choice of trade terms |
| Compliance problems | Understand product regulations, sanctions and labelling rules in each market |
| Over-reliance on one source | Keep a second supplier qualified |
For high-value deals or complex products, consult a trade lawyer, accountant or customs broker. Nothing in this article is legal or financial advice.
Building lasting trading relationships
The best wholesale deals are rarely the cheapest on a spreadsheet; they are the ones that run smoothly year after year. Habits that help:
- Communicate clearly and early, especially about delays.
- Put agreements in writing, even when you trust each other.
- Pay on time and expect the same.
- Share forecasts so suppliers can plan capacity.
- Review performance regularly with simple metrics: on-time delivery, defect rate, responsiveness.
- Treat disputes professionally; most can be resolved by calm discussion and documents.
Common beginner mistakes
- Ordering without a written specification
- Skipping samples or inspection to save a little money
- Ignoring landed cost and being surprised by duties or freight
- Paying everything upfront to an unverified supplier
- Assuming verbal promises are binding
- Not checking whether the supplier is the manufacturer or a middleman
- Leaving customs and compliance to the last minute

Frequently asked questions
What is the difference between B2B and B2C trading?
B2B involves sales between businesses, with larger orders, negotiated terms and more documentation. B2C sells directly to individual consumers at set prices.
Do I need a contract for a small wholesale order?
At minimum, use a detailed purchase order that the supplier accepts in writing. For larger or repeat business, a framework agreement is wise.
How do I know whether a supplier is a manufacturer or a trader?
Ask for factory details, production capacity and references, and consider an audit or visit. Verify claims through independent sources.
What payment terms are safest for a first order?
It depends on your relationship and risk. Options that share risk, such as staged payments or documentary instruments, are common for new partners. Ask your bank about what is available.
Conclusion
B2B trading rewards preparation. Define what you need in writing, compare suppliers on total cost and reliability, agree terms in a clear document, manage payment and shipping risks, and review each deal honestly. Do that consistently, and wholesale relationships become a stable foundation for growth.
