When you begin shipping international orders, there is no additional step when it comes to processing orders within the workflow, but there are considerations you need to take into account before doing so, since international orders require information which local shipments don't on the order level (SKUs, etc) and settings on the Billing Accounts depending on the carrier.
These considerations are the following:
1) Make sure you use international services instead of local services
A common mistake is trying to use local services for international shipments, giving errors when processing, for example, trying to ship an order from Canada to the UK using a local-only service, or shipping an order from the USA to Canada using a local Ground service.

2) The Reason for Export needs to be set for the Billing Account on the Client level prior to processing
To ship international orders, you will have to set the Reason for Export (and sometimes additional information related to it depending on the carrier) for Customs purposes. If those values are not complete, you will face errors when processing until you correct them.

3) Make sure your order has the required shipment destination, weight, format and service information
While local orders do not require packaging information other than for calculating shipping charges, enabling you to ship without SKUs information for example, it is required for international shipments that not only the package information is provided properly, but also the SKUs need to be detailed together with the price, country of origin and quantities. Missing that information will prevent you from shipping until you correct it.

- Operation returned an invalid status code (...) Must have at least one shipping content block [Solution]
- Error "SKU Price information is required for international shipments" [Solution]
4) Make sure you're filling out APO, FPO and/or DPO addresses correctly
It is quite usual to see errors when processing orders shipped to APO, FPO and DPO addresses. Since not all the carriers handle this information the same way (for example, some consider US territories as countries instead of regions or territories), there is not a guide appliable to all of the cases, but measures can be taken to prevent these issues.
Depending on the carrier you will use, make sure that the address you're providing complies with the carrier requirements.

5) Verify that the addresses you're shipping to are correct in every sense
Typos and incorrect placing of cities, states and postal codes can prevent you from shipping international orders. Make sure that the information provided is correct, and if doubtful, avoid using public online services to verify addresses (Google or Bing Maps), and resort to the carriers' official validation tools.
