Send B2B invoice emails automatically from Shopify Flow

Email the invoice PDF to wholesale buyers and CC your accounts team the moment a B2B order is paid, from your own domain.

Order paid→Customer tag is wholesale→Send email + invoice PDF
TL;DR
  • Trigger a Flow on Order paid and check the customer is a wholesale (B2B) buyer.
  • FlowSend emails the buyer from [email protected] with the invoice attached and CCs accounts.
  • Pass the invoice file URL from a Flow variable so every email gets the right PDF.

The problem

Wholesale buyers expect an invoice the moment their order is paid. Doing it by hand means downloading a PDF, writing an email and hoping nobody forgets.

The workflow

  1. Trigger: Order paid.
  2. Condition: the customer has the wholesale tag (or the order has a B2B company).
  3. Action: FlowSend → Send email.
    • To: the buyer’s email.
    • CC: [email protected].
    • Attachment: the invoice file URL from your invoice app.
    • Template: your branded invoice email with order number, total and payment terms.

Why send it with FlowSend

  • It comes from your domain, so buyers recognise it and it’s less likely to land in spam.
  • Every send is in your delivery logs, so you can prove the invoice went out.

Questions

Where does the invoice PDF come from?

Any app or service that gives you a file URL per order, for example an invoice generator app that stores the PDF link in an order metafield. FlowSend attaches the file from that URL.

Can I send to a different billing contact?

Yes. Use a Liquid variable such as a company contact email or a metafield for the To address, and CC your accounts inbox.
