# Online Shops and Marketplace Integration for Small Businesses

**Summary:** Rubra Digital sets up and runs online shops for small businesses in Portugal, such as furniture makers, clothing labels and local retailers, and connects them to marketplaces such as Worten, KuantoKusta, Fnac and Leroy Merlin. The shop takes the payments Portuguese customers expect, issues proper invoices through your invoicing software, and keeps stock and orders from every channel in one place.

A small business does not need to become an online retailer to sell online. It
needs a shop that shows the products properly, takes payment the way customers
expect, and does not create a second job in the back office.

## Built for the Portuguese market

- **Payments**: MB WAY, Multibanco references and cards, the methods Portuguese
  shoppers look for at checkout.
- **Invoices** issued automatically through your certified invoicing software,
  with the ATCUD and QR code.
- **Delivery** priced for what you actually sell, including bulky items, local
  delivery and installation, and click and collect.
- **Consumer law**: withdrawal rights, clear total prices with VAT, and the
  complaints book link.

## Marketplaces without the extra admin

Selling on Worten, KuantoKusta, Fnac or Leroy Merlin brings in buyers you would
not reach on your own. What usually stops a small business is keeping prices,
stock and orders right on several sites at once. We connect the marketplaces to
the shop, or to a simple stock list if you do not have a shop yet, so a sale
anywhere updates the stock everywhere and every order lands in one list.

## Who it suits

Furniture makers and shops, clothing labels and small textile firms launching
their own brand, and local retailers who already sell in store, usually with
fewer than 20 people. [Martibela](/work/martibela), a furniture and mattress
retailer in Agualva-Cacém, runs its online shop on PrestaShop with click and
collect and free delivery and installation in the Lisbon district above a
minimum order value.

## What you get

- An online shop on PrestaShop, WooCommerce or Shopify, chosen for your catalogue
- MB WAY, Multibanco references and card payments
- Invoices issued through your certified invoicing software, such as Moloni or InvoiceXpress
- Delivery options and rates for your products, including bulky items and installation
- A product feed for Google Shopping and listings on the marketplaces that fit your category
- Stock and order sync between the shop and each marketplace

## Outcomes

- Sales from customers who would never have found the shop or workshop
- One catalogue, one stock count and one order list for every channel
- Payments, invoices and delivery that work the way Portuguese customers expect

## Frequently asked questions

### Can I sell on Worten as a small business?

Yes. Worten accepts companies and sole traders as marketplace sellers after registration and approval. You list your products, Worten shows them on its site, and you ship the orders and issue the invoices. It charges a commission per sale that depends on the category, so confirm the current conditions with Worten before you start.

### Which marketplaces make sense in Portugal?

It depends on what you sell. Worten has the widest reach and sells home products as well as electronics. Leroy Merlin suits furniture, home and DIY. KuantoKusta, which started as a price comparison site, and Fnac reach shoppers comparing prices. Most small businesses do best starting with one marketplace, not all of them at once.

### Do I need my own shop if I sell on marketplaces?

Usually, yes. A marketplace owns the customer, takes a commission on every sale and can change its rules. Your own shop keeps the margin and the customer relationship, and it is where your product data lives before it goes out to each marketplace. The two work best together.

### What about invoices?

Every order needs a Portuguese invoice with the ATCUD and QR code, and on a marketplace it is usually the seller who issues it. Connecting the shop and the marketplaces to your certified invoicing software means the invoice is created and sent automatically instead of by hand.
