Where buyers find suppliers
- Manufacturer websites, which often list authorized distributors and resellers by country
- Trade shows and industry associations
- Referrals from other retailers and IT providers
- Search engines, with careful vetting of what you find
Vetting checklist
| Check | What good looks like |
|---|---|
| Business identity | Registered company with a real address, phone and tax numbers on invoices |
| Authorization | Can explain which brands they buy directly or through distributors |
| Paperwork | Commercial invoices, packing lists and serial number lists as standard |
| Grading | Written definitions for new, open box and refurbished |
| Policies | Published warranty, returns and shipping terms |
| Payment | Bank wire to a business account in the company's name; card payments accepted |
| Communication | Named contact, quick written quotes, clear answers |
Red flags
- Prices far below every other source for current models
- Payment only by cryptocurrency, gift cards or to a personal account
- Emails announcing "new bank details" for a pending payment
- No physical address, or an address that is a mail drop
- Refusal to provide serial numbers or invoices with full company details
- Pressure to pay immediately to "secure" stock
Run a test order
Start with a small, representative order. Check delivery time, packaging, paperwork and serial numbers. Register a few units with the manufacturer. If everything matches, scale up.
Questions to ask a new supplier
- Which brands are you authorized for, and through which channel?
- Do you hold stock or order on demand?
- How are condition grades defined?
- What is your DOA and returns process?
- Do you provide serial number lists with every order?
- Which carriers do you use and who covers transit damage?
