You can set the default email your suppliers receive with each purchase order, and choose how your PO PDFs are sized. It is all in Settings, and you can still tweak any individual email before you send it.
Set your default supplier email
In Settings, the Supplier email section lets you set a default Subject and Message for the email that goes out with each PO. Use variables in double curly braces to personalize each send:
{{po_number}}, {{shop_name}}, {{supplier_name}}, {{contact_name}}, {{total}}, {{currency}}, {{expected_date}}, {{item_count}}, {{unit_count}}.
A live preview shows exactly how it will look. You can also:
Include the order summary table (PO number, items, total, expected date) - on by default.
Set a Reply-to address so supplier replies reach the right inbox. Leave it empty to use your store email.
The PDF is always attached to the email.
Tweak an individual email
When you click Email to supplier on a PO, the subject and message are pre-filled from your default, ready to edit. Any change you make there applies to that send only - your saved default stays as it is.
Choose your PDF paper size
In the PDF documents section of Settings, choose Letter (8.5 x 11 in) or A4 (210 x 297 mm). This applies to downloaded, printed, and emailed purchase order PDFs.
Good to know
If you use a variable name Stockroom does not recognize when saving a default, it points it out, so nothing sends with a broken placeholder.
Emails send in the background, so "Email sent!" means it is on its way. Replies go to your reply-to (or store) address, not to Stockroom.
