Short answer: A safe wholesale purchase starts with a precise stock specification, a supplier and company check, a comparable written quotation, representative sampling and an agreed receiving procedure. Model and unit price alone are not enough to evaluate a used iPhone batch.
Define the stock your market can sell
Start with the customer segment rather than the supplier list. Identify the models, storage capacities, colours, cosmetic grades, battery thresholds and SIM configurations that fit your resale channel. A physical retailer may prioritise consistent appearance; a value marketplace may accept more visible wear if the functional standard and margin are clear.
Write a purchase brief with acceptable substitutions. For example, state whether mixed colours are permitted, whether quantities may move between storage variants and whether regional versions or eSIM-only models are acceptable.
Verify the supplier and offer
- Confirm the legal company name, invoicing entity, business address and payment beneficiary.
- Ask how devices are sourced, identified, tested, graded and recorded.
- Request the grading definition, functional test scope and lock-status policy.
- Check that the quotation identifies model, storage, grade, quantity, price, currency, VAT treatment and Incoterm.
- Clarify stock-reservation time, payment deadline, dispatch estimate and discrepancy process.
Compare the full landed cost
| Cost area | What to include |
|---|---|
| Stock | Unit price multiplied by confirmed quantity |
| Commercial | VAT treatment, payment and currency-conversion costs |
| Logistics | Packaging, freight, insurance and customs handling where applicable |
| Operations | Incoming inspection, cleaning, data processing, accessories and relabelling |
| Risk | Expected downgrade, repair, return and slow-moving inventory allowances |
Use samples and batch evidence
A sample can confirm how a supplier applies its grade, but it does not prove every device in a later batch will look identical. Ask whether the sample comes from the offered stock and how batch tolerance is controlled. For larger orders, agree on stock-list fields and evidence before payment.
Receive and inspect methodically
Record package condition on arrival, reconcile the quantity and IMEI list, and inspect a risk-based sample immediately. Keep device identifiers linked to test results. Report shortages or material differences within the period stated in the commercial agreement, with clear photographs, video and affected IMEIs.
Review the IMEI and lock-status guide, grading guide and shipping guide before confirming a first order.
Frequently asked questions
What information should an iPhone wholesale quotation contain?
It should identify the product specification, quantity, unit price, currency, tax treatment, Incoterm, payment terms, stock validity and expected dispatch timing.
Should a first-time buyer order samples?
Representative samples are useful for aligning grading and testing expectations. They should be combined with a written batch specification because a sample cannot define every unit.
What is more important: price or grade?
Neither can be assessed alone. Compare landed cost, sellable yield and expected resale value for the same written cosmetic and functional specification.
