About Integration with FGO invoicing

Our integration app is able to automate the process of generating invoices, and registering payments on the invoicing system. FGO is a Romanian online invoicing system which provides the API to for this app.

Each time an order is created, an invoice can be automatically created. Each time a payment is captured, the app can update the linked invoice as paid on the invoicing system.

Multiple options let's you customize the app's behavior.


  • Automatic invoice creation - If checked, each time a new order is created by a customer, the system automatically creates an invoice for the order using FGO service.
  • Automatic action on Order Paid - When an order's payment is captured we can mark the invoice as paid in FGO.
  • Automatic action on Order Cancelled - When an order is cancelled we can automatically cancel or delete the associated invoice from FGO.
  • Invoice Serial - If left empty, FGO will use the default series defined, if there is any. If you set a serial, make sure it is defined in FGO and the API user has the access rights to use it.
  • Invoice Number - The invoice number can either be set by FGO according to the serial registry or you can force the invoice have the same number as the order.
  • Invoice client type - Specify if the invoices are for a company or for individuals.
  • Unit of Measure - This will be used for all items in the invoice.
  • VAT rate - This is the rate used for all generated invoices.
  • Pay VAT at collection time - Special flag - to be checked if the seller company pays VAT when the invoices are collected (TVA la incasare).


  • The monthly price plans above refer only to the Shopify app offered by WebShopAssist, and not to the FGO price plans.
  • The monthly invoice limits are also only for the Shopify app. FGO does not set limits for the number of invoices created.
  • In order to use this app, you need the FGO Premium price plan. Currently, only this plan gives access to the API used by this app.
