Entering supplier invoice products without losing your evening

A delivery arrives, the supplier invoice runs three pages, and you need to create forty product listings with the right sizes, colors, prices and photos. This is the moment when most independent shops fall behind and rush the catalog. Here's how to take back control of this step.

The invoice already contains almost everything: references, quantities, sizes, colors, cost prices. The real work is not retyping them by hand.

What a delivery really costs you

  1. A 40-line invoice takes 4 to 8 hours of manual entry on average.
  2. Every day of delay means items sitting in the stockroom that can't be sold online.
  3. Entry mistakes (size, color, price) get paid for later: returns, disputes.

What a supplier invoice actually contains

An invoice or delivery note already contains the essentials of a product listing: supplier reference, EAN when included, product label, variants (sizes, colors), quantities and cost price.

The classic trap

The price on the invoice is a cost price, not a selling price. If it goes straight into the listing as-is, the shop sells at a loss without even noticing.

The four possible methods

Method Time for 40 refs Main limitation
Manual entry 4 to 8 h Fatigue, variant mistakes
Supplier's CSV file 1 to 3 h Few suppliers provide one
Outsourced data entry 24 to 72 h Recurring cost, back-and-forth
Automated invoice reading A few minutes + review Still needs validation

The five-step method

  1. Start from the invoice, not a blank page. One line per reference, without retyping. What isn't written shouldn't be invented.
  2. Match each line to a real product via the EAN or supplier reference, to find name, brand, material and official photos.
  3. Group variants under the right listing. One model in several sizes/colors = one listing, one variant per combination. Check the photo matches the color.
  4. Set the selling price, not the cost price. Apply your markup once, keep the cost price to track your real margin.
  5. Review, publish, sync. Title, photo, variants, stock, price — then send to your online store and register.

Why a sloppy listing costs you for a long time

A listing with no description, brand or specifications sells poorly, but above all it can't be found: search engines and AI assistants rely on structured data. The time invested isn't judged on delivery day — it's judged three months later, when the product does or doesn't resurface in a search.

The takeaway

The supplier invoice already contains 80% of the product listing. Your real value-added work is pricing, review and variant consistency — not retyping. Refect reads the invoice, finds the matching products, and prepares the listings with photos, variants and stock.

FAQ

What if the invoice has no EAN code?

The supplier reference combined with the brand name usually lets you find the product on the manufacturer's website. Our guide to finding an EAN code covers reliable sources.

Should I create one product per size, or one product with variants?

One product with variants, in almost every case. This avoids splitting your sales history and simplifies restocking.

Can the price printed on the invoice be used as the selling price?

No. In the vast majority of cases it's a cost price before tax. Apply your markup and treat any recommended selling price as a mere suggestion.
