Sure, importing invoices from QuickBooks into Odoo while keeping the origianl invoice date adn ship dates intact is definitely do-able. The main challenge here is gettin' the data mapping right during the import process. In Odoo, you can use the import function in the Invoicing app. When you prepare your CSV or Excel file for import, make sure it includes columns for invoice dates and ship dates that map to the corresponding fields in odoo.

first, ya gotta make sure your Dates are formatted correctly in your CSV to match Odoo's format, usually YYYY-MM-DD. And you’ll want to match the invoice data fields exactly so odoo knows where to place this data. On the import screen in odoo, there’s an option to map each column in your file to a field in Odoo. Do this carefully to avoid mixups. Simple, but it can trip ya up if you're not careful!

One more thing, when you’re dealing with batch invoices, double-check you're importing them with the correct currency and tax details are aligned with Odoo’s settings to avoid mismatches. I'd say, if you hit a snag, you might want to get advice from someone who's worked with both systems to make it smoother.
