QuickBooks Add-On

Enabling the add-on will send all new invoices from ActiveCollab to your QuickBooks Online account for further processing. After sending an invoice to QuickBooks, you won't be able to edit it in ActiveCollab anymore.

Also, all invoices made before connecting to QuickBooks, as well as the entire Estimates section will become unavailable. However, they won't be removed and will reappear if you disconnect QuickBooks.

Connecting to QuickBooks 

• Open Add-Ons and click Configure next to QuickBooks,
• Redirect URI in Quickbooks should be: https://your-url/integrations/quickbooks valid only for self-hosted,
  
• Click Connect to QuickBooks,
  
• Sign in and click Authorize.
  

Connecting Self-Hosted ActiveCollab

Before you can connect, you'll have to provide the OAuth Consumer Key and OAuth Consumer Secret. To get those, open a developer account, create a new app, deploy it, and copy its keys to ActiveCollab. You'll also have to choose the company you're connecting to.

Creating an Invoice

• When creating a new invoice in ActiveCollab, you'll be able to choose a client from the list of companies from QuickBooks,
  
• You can then select the desired projects, which time and expense entries to include, and how to group them,
  
• To create the invoice, click Proceed creating an invoice in QuickBooks.
  

The newly created invoice will be sent to QuickBooks and show up under the selected client. There you can finish creating the invoice and send it.

How It Works

• Editing an invoice in QuickBooks will update the amount in ActiveCollab,
  
• Sending will mark the invoice as sent,
  
• Paying will mark the invoice as paid,
  
• Voiding will mark the invoice as canceled,
  
• Deleting will delete the invoice in ActiveCollab as well.
  

Disconnecting QuickBooks

When you disconnect, all the invoices you sent to QuickBooks will become unavailable in ActiveCollab (but they'll stay in QuickBooks).

They'll reappear in ActiveCollab if you connect QuickBooks again.
