Distributors choose in layers, and price is rarely the first one. The working order is: evidence first — documents that prove the product is what it claims to be; then the product in hand; then commercial terms, settled in writing; then the relationship over time. A supplier that fails an early layer never reaches the price conversation.
Key Takeaways
- Distributors choose in layers: documents, product in hand, written terms, relationship.
- Layer 1 is nearly free and filters out most weak suppliers — run it first, on every candidate equally.
- Commercial terms matter as written fields, not as values promised in conversation.
- The distributor carries the customer’s risk, so fault handling weighs as much as price.
Layer 1: Documents Before Meetings
Documents are the cheapest evidence a distributor will ever buy, so they come first. The same pack is requested from every candidate, keeping the answers comparable:
| Document | What the distributor is really checking |
|---|---|
| Spec sheet for the exact model | The field set is complete and the figures match the test report — a sheet that disagrees with the report ends the enquiry early |
| Test reports and certificates | The holder named on the file is the company being paid, and the listing body is recognised — in the U.S., under the OSHA NRTL program |
| Warranty terms in writing | Term length, freight on replacements, whether spare parts are sold separately |
| Manuals and labels for your market | The documentation exists in your market’s language and matches the certified configuration |
Score the replies, not the brochures. Complete, consistent documents show a supplier’s internal order; gaps and mismatched names are layer-1 failures — and they cost almost nothing to find.
Layer 2: The Product in Hand
Paper proves a model was tested; only a unit proves what ships. Distributors therefore order samples through the normal sales channel, in the exact configuration they plan to sell, and keep one unopened as the reference unit for later shipments. What gets weighed here is behaviour, not specification: build quality against the price class, the sample’s label against the layer-1 documents, and how the supplier handles the awkward questions the sample raises. Our checklist on choosing a portable EV charger supplier covers the first-order questions in this layer.
Layer 3: Commercial Terms, as Written Fields
Only suppliers that pass the first two layers earn a terms discussion — and the distributor’s job there is to turn promises into written fields:
- Territory and exclusivity: a field to settle explicitly in writing, never an assumption.
- Minimum order per model: the number that decides whether the range fits your warehouse and cash flow.
- Lead time, with its basis: from stock, from production, or from components — three different promises.
- Spare parts: which parts are stocked, for how long, and at what price basis — the field your warranty promises depend on.
- Price-change handling: how a quote holds, and what notice a change requires.
- Branding scope: exactly which surfaces, documents and app elements carry your brand, and which stay the factory’s.
None of these fields has a “right” value in the abstract — the test is that each is answerable in writing before money moves.
Layer 4: The Relationship Tests
The last layer runs the whole time the others do. How are faults handled when they happen — the process in our guide to how suppliers should handle common faults is the standard to compare against. Are component substitutions announced before they ship, or discovered by your customers? Does a hard question reach an engineer, and how fast? Distributors weigh the answers heavily: they, not the factory, face the end customer when a charger fails in year two.
Running the Ladder on EVDANCE
Apply the same ladder to us. EVDANCE is a Shenzhen manufacturer founded in 2011, with its own factory, exports to more than 30 countries, private label from 100 units and a 3-year standard warranty. The resellers and distributors program is the entry point; commercial hardware such as the EV-AC03201T dual-connector AC station (two Type 2 connectors, up to 43 kW shared, OCPP 1.6J, RFID, IP54) sits in the product range. Send the layer-1 document list first, and judge the reply as you would any supplier’s.
Frequently Asked Questions
Should price ever be the first filter?
Only as a rough sanity band. The cheapest quote that later fails on documents, parts or warranty handling is the most expensive supplier a distributor can choose.
What if a supplier will not share full test reports?
Treat it as a layer-1 failure. Certificates alone, or marketing summaries, are not substitutes for the report on the exact model — the basic evidence the whole ladder stands on.
How many suppliers should a distributor end up with?
Commonly one main supplier per product category, with the ladder’s runner-up kept warm. Splitting volume weakens every layer-3 field you negotiated; having no alternative weakens you when a layer-4 problem arrives.
