Goal of this tutorial

In this tutorial, you will:
  1. Sign up for an Invopop account and get your first sandbox workspace working.
  2. Invite your colleagues to join your workspace.
  3. Create a simple workflow to issue an invoice.
  4. Upload the invoice to the workflow and process it.

​
Signing up

Let’s start by signing up for an Invopop account.
  1. Go to https://console.invopop.com and select your sign up method (email or Google).
If you’re using Google, you’ll be redirected to the Google sign up page, otherwise you’ll receive an email with a code to verify your account.
Sign up form
  1. Fill in the form with your name, company, and position. The company will become your organization in Invopop, more on that later.
Sign up form
  1. You’ll be prompted to create a first sandbox workspace. Don’t worry, you can always create more workspaces later.

​
Creating a workflow

Now let’s create your first workflow. We’ll start with a simple workflow that generates a PDF invoice.
  1. Go back to the workspace, by clicking on the Workspaces tab, selecting your workspace and clicking on Go to Console or simply opening a new tab in https://console.invopop.com.
Go to workspace
  1. Click on the Workflows on the left sidebar. You’ll see a list of all the workflows in your workspace.
Workflows
  1. Click on the Create workflow button on the top right corner. You’ll see a list of template workflows that you can use to get started.
  2. Select the “PDF Invoice” template and click on Load template.
  3. Let’s add a step that sets the Document state to Sent after the PDF is generated. Click on the + button below the top right corner and select Set State in the right sidebar.
Add Set State step
  1. You should now see the configuration of the Set State step, otherwise click on the step you’ve just added. Select Sent in the State dropdown.
  2. Click on the Save Draft button save your draft workflow. Now click on Publish so you can start using it in your workspace.

​
Uploading an invoice

Now let’s upload an invoice to your workspace that we’ll later send to the ‘PDF Invoice’ workflow. You can upload document manually from the Console or by using the API.
  1. In the Console, click on Invoices on the left sidebar.
  2. Click on the New invoice button on the top right corner. You’ll be redirected to the document editor.
  3. The document editor has two modes: the visual view and the code view. Switch to the code view by clicking on the toggle below the Save button.
Toggle code view
