Thanks for your post - it's not currently possible to map CIS using EZ mapping codes, instead, you'd need to use one of the default custom form templates when raising CIS invoices. As a workaround, you could use one of the custom fields for CIS and map this on the imported invoice, however, you would then need to manually input the amount when raising invoices. We'd recommend leaving feedback through QuickBooks (Cog > Feedback) for further Import Style options as this feedback goes through to our developers who work on this function. 👩💻
