Ubercart

Hmm... you might be able to work it like a second flat rate that shows up as "Call for quote: $0.00" or something on the checkout form. Then you can just authorize their card but not capture any money until you adjust the order to include the actual shipping amount. Not perfect, but it should get you started in the right direction.

I tried, but I'm still puzzled. I did replicate in conditional actions what's been described for workflow-ng. But I don't get the shipping quotes to be calculated. What I'm trying to achieve (in UC2):

For domestic shipping addresses: Calculate flat rate and/or weight quote.

For international: Show a message and send email to the customer informing him that the order will have to be updated by the shop admin with a shipping quote. (And process the order after that is done.) Like Ryan said: just authorize their card but not capture any money until you adjust the order to include the actual shipping amount. Possibly replace this later by a fully automated (but probably rather complicated) set of predicates and modules to calculate international shipping quotes.

Generally I find it tricky now to get the right directions, since forum posts on shipping revolve around various versions and modules: UC1 with workflow-ng, UC2 with conditional actions, uc_worldquote, uc_regions, uc_tablequote, cif files (do I need to import one for every country I ship to?)...

Would be great if someone who solved a similar situation could give some guidance on how the shipping quotes and conditional actions modules should be configured for some example use cases... Or possibly point to some in-depth documentation.

Thanks!
