A strong start prevents problems later on. Make sure you have the following in place⬇️

Active seller account

Ensure you have a fully active and approved business seller account before you start exporting products.

Correct EAN and SKU structure

EANs and SKUs form the basis of your integration.

  • Use unique and valid EANs that are GS1 approved. Most marketplaces match by EAN.
  • Avoid duplicate EANs in your assortment
  • Work with correct SKUs so that your system correctly recognizes and links items. SKUs are the internal basis for your inventory, pricing, and order processing. Varying or deviating SKUs increase the risk of errors in your linking and processing .

➡️An incorrect or invalid EAN often leads to incorrect matching or rejected products.

Detailed product information (content)

The more product information you provide, the easier your products are to find and the easier it is for the customer to make a purchase.

  • Every marketplace has its own rules regarding content. For example, one marketplace requires the brand to be included in the title, while another does not. You can find these rules in their content guidelines.
  • You can supply content to us via attributes from your own webshop/backend, via an additional source , or custom attributes .
  • Fill in the attributes in the content mapping within EffectConnect as completely as possible.

➡️ Incorrect or incomplete content results in disapproval or poor visibility.

Fair prices and margins

A good selling price is more than just generating revenue or being the cheapest.

You actively aim for profit, even after all marketplace costs have been paid. Instead of only looking at competitor prices, you consciously include all costs: commission, shipping, returns, and other fees.


Start with your cost price

First, calculate what a product really costs you.

Consider:

  • Purchase price

  • Shipping costs

  • Pick & pack costs

  • VAT

  • Fulfillment costs

  • Marketplace commission (percentage and/or fixed amount)

    ➡️ Only then should you set your selling price.

     


    Take marketplace commissions into account

    Every marketplace charges a commission per product sold. This varies by category.

    Examples:

    • Bol → often between 4% and 20%, and depending on sales amount + fixed amount

    • Amazon → often 7% to 15%

    • DIY marketplaces → often fixed fee + commission

    ➡️This is how you prevent a low-margin product from becoming unprofitable.

     


    Don't forget shipping costs

    Shipping costs have a significant impact, especially at low selling prices.

    Check:

    • Free shipping yes/no

    • Shipping rates per carrier

    • Surcharges for large or heavy package

    • Foreign allowances

    ➡️Use our storage or custom attributes module to add shipping costs

     


    Determine a minimum margin

    Always work with a minimum margin limit.

    Many sellers focus on:

    • minimum 10–15% net margin

    • or a fixed minimum profit amount per order

    That prevents you from:

    • Revenue generates without profit

    • too aggressive reprice

    • incurs losses during price competition

    ➡️Low revenue with a healthy margin is often better than high revenue without profit.

     


    Don't just look at the lowest price

    The cheapest seller doesn't always win. Marketplaces also look at:

    • delivery time

    • stock

    • seller performance

    • reviews

    • fulfillment type (such as LVB/FBA)

     

    Use the repricer

    Our repricer allows your prices to dynamically and automatically move with the market, based on threshold amounts you set.

    1. Repricer General

    ➡️This is how you stay competitive and get the most margin from your sales.

    Would you like to know if the repricer is suitable for your product range? Contact our Customer Support team for more information.

     

    Monitor your performance

    Analyze:

    • which products are profitable

    • which products have high revenue but low margins

    • which products cause many returns

    • Which products have the buybox, but can you take even more margin?

    • Which products do you have in stock but are offline?

    • Which error messages are returned on the offers (logs)

    ➡️This is how you discover which products truly contribute the most to your marketplace sales.

    We offer various consulting options to gain insight into this: consultations that accelerate your marketplace growth.

Respond to external factors

External factors have a direct impact on your performance.

  Prevent strikes , don't wait, and proactively adjust your delivery times within EffectConnect.

Delays at carriers

  • Busy periods, often around (national) holidays
  • Weather conditions, such as snowfall

Holiday period

  • Can you continue to guarantee quality standards – such as delivery time and response time – during the holiday period?
    • If not, put your account temporarily on vacation mode or adjust your delivery times.

➡️The marketplace expects you to honor your delivery promise.
