If you do wind up needing to add shipments manually, you can save each customers’ information in Sendcloud and reuse it when the same person orders from again. This will save you from having to retype everything multiple times.
There are two ways to do this. While editing an order or creating a shipment, simply check the “Save this contact” checkbox. That’s it! Or, if you just want to add contacts without creating a label, go to Settings, Saved contacts, click “Create contact”, and fill out the form. After the first contact is added to the list, a search box will appear in your manual shipment form. Here you’ll be able to search for a customer and add their contact info in just one click.
