Getting started

First online shop: one product or a small range?

Start with a single product if your budget cannot support samples, checks and useful sales exposure across a range. Choose a small, related assortment when you need to test buyer preference and can fund each item properly within the same cash cap. Agree the trial brief before supplier searches with Cambridge China Bridge.

Choose what the trial must teach you

For your first eBay or Shopify shop, decide whether you are testing demand for a particular offer or choosing between related products. A single product concentrates stock, listing work and promotion, but leaves you exposed if that choice fails. A small range can reveal preferences, but spreading the budget can leave each listing with too little exposure to judge.

Keep the intended buyer, selling channel and review period consistent. Related products serving the same customer need are easier to compare than unrelated cheap finds. Use the first-order forecast guide to set demand assumptions; here the decision is how widely to spread the trial.

Compare complete plans under the same cash cap

Set the total cash you can commit through the review date, including a reserve for refunds and problems. Prepare alternative plans using that same ceiling. Include samples and sample delivery, checks, goods, import charges, freight, packaging, selling fees, promotion and customer parcels. Mark unquoted costs as unresolved rather than treating them as free.

For example, compare a compact stock product with a related assortment containing a bulky item and an item needing separate checks. The assortment may offer more choice but leave less cash for saleable stock and promotion. Remove candidates until the whole plan fits. Use maximum affordable factory price for the detailed cost calculation.

Count samples and compulsory pack contents

List the sample work needed for every candidate, including delivery and possible revisions. Do not approve an assortment because the catalogue photographs look consistent. Check the actual products, their packaging and the proposed production specification. Ask what sample costs would be credited later, but keep the upfront payment in the cash plan.

Translate each supplier minimum into stock you must actually buy, including fixed size and colour packs. A nominally single product can still create an assortment of variants. Compare unwanted pack contents with the stock you intended to test. Use minimum packs, sizes and colours for the pack worksheet.

Resolve compliance evidence before buying stock

Products should only be sold once compliance with product safety regulations has been appropriately demonstrated. Put the evidence review before the stock commitment in either plan. A cheap purchase price is not a reason to leave this work outside the budget.

For each candidate, record its intended use, materials, model reference, proposed sales territory and available reports. Ask a competent adviser which evidence and further checks are needed, and budget their quoted cost. Ask whether reports actually cover the proposed variants; do not assume related products can share evidence. If the scope or cost remains unresolved, leave the candidate out of the buying plan.

Check the parcel economics and the sales signal

Check packed dimensions, weight and protection for each item, then obtain delivery quotes for individual orders and likely combined baskets. Compare packaging, picking work and returns handling as well as postage. A cheap bulky product can consume the delivery budget; related products only help basket economics if customers actually buy them together.

Record listing visits, promotion spending, orders, refunds, delivery costs and remaining stock by product. Give each candidate planned exposure and record differences in price, availability or promotion. Low sales with little traffic do not establish weak product demand. In a mixed basket, distinguish an item bought alone from an add-on. Use when to scale up before turning the result into a larger order.

Send a bounded brief before supplier searches

Write down the chosen trial structure, intended buyer, sales territory, cash cap, acceptable unsold stock and learning goal. Add candidate specifications, sample acceptance checks, permitted pack contents, evidence questions and parcel assumptions. State which unresolved costs or conditions would stop the purchase.

Use support for ecommerce sellers and small-order sourcing to brief Cambridge China Bridge. Its staff in China can investigate supplier options against those limits. If no workable offer fits, narrow the range, change the specification or postpone buying; keep approval of the final products and quantities with you.

Frequently asked questions

Should I start my eBay or Shopify shop with one product?

Choose a single product when you need to test a defined offer and cannot properly fund a range. Choose related products when preference is the question and each can receive samples, checks and useful sales exposure within your cap.

Are several cheap products safer than a single product?

They spread product-choice risk, but can multiply preparation costs and unwanted stock. Compare the complete cash commitment, compulsory packs and parcel costs before deciding.

Can I use the same test report for the whole range?

Ask a competent adviser to check the report against each model, material and variant. Budget any further evidence work before buying; similarity in catalogue photographs is not enough to decide coverage.

What if none of the products sells?

Check traffic, availability, price, delivery offer and promotion before blaming the products. If exposure was insufficient, the result is inconclusive. Review the remaining cash and stock before funding another test.
