Oktagon Fortnox for Shopify

Thank you for trying out or app, if you have any suggestions for improvements please let us know at [email protected].

The main idea for this app is make automatic Fortnox bookkeeping as easy as possible, the focus is on saving time for you. The app automatically registers: currencies, customers, articles (products) and then optionally also: orders, invoices, booked invoices and vouchers.

How to get started

To get started with this app there are three things you need to do:

1. Activate a billing plan, all plans have a free trial period. If you wish to cancel the trial just uninstall the app from your shop.
2. Connect the app to your Fortnox company, to be able to do this you need to have access to your Fortnox company and have the permissions to connect the company with Fortnox apps.
3. Select preferred settings in the app and save, more information regarding settings below.

Settings

There are two sections of settings, Automation and Bookkeeping accounts. To save settings click the Save button in the top right of the screen.

Automation

Automation settings consists of checkboxes turning features on and off.

• Orders, enabling this will create Orders in Fortnox when Orders are created in Shopify. An Order in Fortnox usually means that it is something that is not yet delivered and therefore not yet invoiced, so an invoice has not yet been created. If you are using Orders and Invoices in the app, the future Invoice in Fortnox will be based on the Order.
• Invoices, when an Order in Shopify has been delivered an Invoice is created in Fortnox. This is something that the customer of the Order is expected to pay for in the future, it has a due date in the future.
• Book Invoices, this means that the generated invoice cannot be edited in Fortnox and it is registered into your companies bookkeeping automatically.
• Create Voucher, when an Order in Shopify is marked as paid, then if you are using Booked Invoices then a invoice payment will be registered in Fortnox marking the Invoice as paid and automatically generating Vouchers in Fortnox. If you are not using Booked Invoices then manual Vouchers will be created.

The recommended workflow is to enable all these settings.
