Practical answer: Use this guide as a purchasing checklist, then confirm model-specific functions, accessories, packing, documents and support in the signed quotation.

1. Start with customer demand, not supplier catalogues

List the treatments your salons, clinics or resellers request most often. Group them into clear needs such as pigment removal, body contouring, muscle sculpting, facial lifting or LED skin care. A focused range is easier to explain and support than dozens of overlapping machines.

2. Build an entry, core and premium position

For each important category, compare a compact entry model, a core model with the most requested configuration and a premium platform for stronger differentiation. Functions, handles, workflow, training and packing cost should support the price difference.

3. Compare the complete configuration

Ask the manufacturer to connect every model number to a written configuration and packing list. Confirm voltage, frequency, plug, interface language and exact accessory quantities before comparing quotations.

4. Calculate landed cost and service workload

Include packing volume, freight, import charges, spare parts, training time and likely service communication. A lower machine price does not automatically create a better product.

5. Check whether your team can support the technology

Decide who will explain installation, operation, routine care and troubleshooting. Confirm which training media and remote support the supplier provides.

6. Test demand before deeper customization

Start with a standard or lightly customized machine. Once demand and the preferred configuration are clear, deeper OEM or ODM work can create stronger differentiation.
