It's possible to set up your InDesign document so the back and front page are shown as a spread instead of being two separate pages.
When creating the document, set it up with the wanted Number of Pages, enable Facing Pages and set Start Page # to 2.
Now your document only consists of whole spreads:
But the page numbers are wrong which will give you problems if you use automatic page numbering etc.
Right-click the first page (which is supposed to be the last page), enter Numbering & Section Options and set Start Page Numbering at to the last page number. Then right-click the second page (which is supposed to be the first page), enter Numbering & Section Options and set Start Page Numbering at to 1.
Now your document should have the proper page numbering:
Beware that if you export a single page PDF with All pages, it will start with the last page. To get the the front page as the first page you need to specify that you want to export pages 1-[second last page number], [last page number]. (If you have 8 pages it would be 1-7,8.)
If you export a PDF in spreads there is no way you can get the front and back to show as single pages.
