# What RUIT is: one inventory for seven marketplaces

One product, seven marketplaces, a single inventory with price and stock in sync. What RUIT connects, what it does on each one and what is free.

RUIT is for **selling the same thing in several places at once without keeping seven
inventories**. You create the product once, choose where to publish it, and RUIT keeps the price
and the stock where they belong on every marketplace. Today it connects **seven**: Wallapop,
Vinted, eBay, WooCommerce, Shopify, PrestaShop and Todocolección, and it has **IberLibro** in beta.

## One inventory at the center

Each product lives **once only** in your RUIT inventory, with its photos, its price and its stock.
That is where its listings come from: the same product can be published on Wallapop, on Vinted and
in your Shopify store, and it is still a single product page. When you change the price or the
stock, RUIT carries the change to every marketplace where it is published. When you sell it on one
of them, RUIT deducts the stock and, if you have set it up that way, takes the listing down on the
others so you do not sell it twice.

It works the other way round too: the listings you already have live are **imported** into the
inventory, so you do not start from scratch.

## Three ways of connecting a marketplace

Each marketplace connects in one of these three ways, and that explains almost everything else:

| Marketplace                            | How it connects                                                                  |
| -------------------------------------- | -------------------------------------------------------------------------------- |
| Wallapop and Vinted                    | Through the **Chrome extension**, because they have no public API                 |
| eBay                                   | By granting permission on its own site, without typing any password               |
| Shopify, PrestaShop and Todocolección  | With keys you paste into RUIT                                                     |
| WooCommerce                            | Accepts both ways: grant permission from the store, or paste its keys in by hand  |
| IberLibro, in beta                     | With keys from your bookseller account                                            |

> **Tip:** If you are going to sell on Wallapop or Vinted, the Chrome extension is not an extra: it is the
> only way RUIT has of talking to them. It uses the session you already have open in your browser,
> which is why RUIT never asks you for the password to either of them.

The three routes are explained in
[how connecting an account works](https://ruit.es/en/docs/how-account-linking-works/).

## What RUIT does on each marketplace

Not everything reaches all seven. This is what there is today:

- **Publish and import**, on all seven. You can bring over the listings you already have live.
- **Keep price and stock in sync** on all seven, so you do not have to edit the same
  product five times.
- **Read and answer messages** from a single inbox, but only on **Wallapop and Vinted**.
  Conversations from eBay can reach the inbox, but you cannot answer them from RUIT.
- **Search and compare** products for sale, on **Wallapop, Vinted and eBay**. You can save a
  search on **Wallapop and Vinted**; having it alert you as well when something new appears is
  a paid feature.

On top of that sits the inventory, which belongs to RUIT. You will see your orders there too, but
those are brought in from the marketplace, so they depend on the connected account, and today they
only come from **Wallapop, Vinted and Shopify**.

## What is free and what is paid

With the free account you have **search**, the **product page**, **saved searches**, connected
**marketplace accounts** and the **inventory**, with no time limit.

What you pay for is what saves you work: **publishing** from RUIT, keeping **price and stock in
sync**, the **message inbox**, the **alerts** from your searches and the **automations**. You try
all of that free for **14 days** on the Pro plan, with no card and no automatic renewal: the trial
starts when you finish the welcome, right after creating the account.

> **Warning:** One practical figure before you dive in: bulk publishing runs in batches of **50 listings per
> job**, counting each product for each account you publish it on. Ten products on five accounts
> make up a whole job.

## Where to start

The route is the same for everyone, and it is the one the app's own first-steps list sets out for
you: create the account, install the extension if you are going to sell on Wallapop or Vinted,
connect the first account, import what you already sell and publish.

**Next step:** [creating your account](https://ruit.es/en/docs/create-your-account/). If you already have one,
carry on with [installing the extension](https://ruit.es/en/docs/install-the-extension/).
