Automatic invoicing in Vendus.

For Rioko to issue invoices in Vendus, the account needs the Flex or Pro plan, a connection to the Portuguese tax authority (AT) and the API turned on. This guide lists the requirements and shows how to make the connection. After that, every payment received on Shopify, Stripe, Lodgify, Easypay or EuPago becomes a document, and every refund a credit note.

01What you need

Vendus on the Flex or Pro plan, connected to the AT.

02Time

About 10 minutes, if the AT connection is already done.

03Price

€7.50 + VAT per month or €75 + VAT per year, per integration.

BEFORE YOU START

What you need to have

Check these points before opening Rioko's wizard.

One invoice per payment

If the same payments are already invoiced in another program, through Rioko or another system, turn that invoicing off before activating this one. The same payment would end up with two invoices.

01

Choose the integration in Rioko

At rioko.online, signed in.

  1. 1Open Integrações.
  2. 2Under Plataforma de Pagamento / E-commerce, choose your platform. Under Plataforma de Faturação, choose Vendus.
  3. 3Click Configurar Agora.
  4. 4Step 1 connects the payment platform. Each step's Ver como se faz button shows where each value is.
02

Copy the API Key in Vendus

Rioko only needs this key.

  1. 1In Vendus, click your name, in the top right corner, and choose API.
  2. 2Check that Acesso API is Ligado (on).
  3. 3Copy the API Key.

Treat the key like a password

The API Key authorises the creation of tax documents in your account. Do not share it by email, chat or screenshots.

03

Paste the key into Rioko

In the Vendus step of the wizard.

Vendus API Key
The key you copied.
Environment
Produção (production) for real documents. Sandbox issues in test mode, with no tax effect.
04

Invoice settings

Till, VAT, sending to the buyer and exemption.

Till
With a single till, documents are issued on that one. With several, choose one. The till belongs to a shop, and the shop defines the series.
VAT included
Does not change prices. On, it authorises Rioko to recalculate the rate when a tax registration is connected (OSS, regional rates, reverse charge).
Exemption reason
Applied when the invoice has 0% VAT.
No drafts in Vendus

Vendus issues the final document at once. To validate first, choose Sandbox in the credentials and switch to Produção at the end.

05

Activate and test

Check the first document before letting invoicing run on its own.

  1. 1On the same page, activate the integration's subscription (monthly or yearly).
  2. 2In the last step, click Marcar como Ativo (Mark as active).
  3. 3Make a small payment on your platform.
  4. 4On the Dashboard, under Últimos documentos, you see the payment and the document's status. Open the document in Vendus and check totals, VAT and customer.
Tested in Sandbox?

Test documents have no tax effect. When everything is right, switch the environment to Produção.

FREQUENTLY ASKED QUESTIONS

Frequently asked questions

Does the Vendus Base plan work for connecting to Rioko?

No. The Vendus API is included in the Flex and Pro plans, and Rioko connects through the API.

Where do I find the Vendus API Key?

Click your name, in the top right corner of Vendus, and choose API. Check that Acesso API is Ligado.

Do I have to specify the Vendus till?

Only if you have more than one. Rioko reads the account's active tills and, if there are several, asks you to choose one.

How do I test the connection without issuing real documents?

Choose Sandbox in the environment. Vendus issues in test mode, with no tax effect.

Does the document stay as a draft in Vendus?

No. Vendus issues the final document at once. To validate first, use the Sandbox environment.
