Is it possible to perform contact data precheck in store? By default, Administrator contact data are hidden, Use account data is selected. Billing contact and Technical contact data are also hidden with Same as administrator contact selected. As a result, if some data are wrong end customer will have to press Checkout to know and correct that.
That is not possible at present. Feature request PBAS-30333 was submitted and is considered to be implemented in future OBAS releases.
