SendFlow · Early Access

Print to WhatsApp. Simple.

SendFlow is a Sunflower Technology product that turns any Windows print job into a WhatsApp PDF delivery — so teams stop saving files, hunting folders, and attaching documents by hand.

SendFlow: print, confirm recipient, deliver on WhatsApp
Built for transactional business documents Invoices, quotations, receipts, and job cards — from the apps you already use.
A Sunflower Technology product

Fewer steps than paper — or the save-and-attach dance

SendFlow installs as a Windows virtual printer. Print from Word, Excel, a browser, accounting software, or a legacy app, confirm the WhatsApp recipient, and SendFlow delivers the PDF as a WhatsApp document.

During Free Early Access, delivery uses a shared SendFlow WhatsApp number. Every message identifies the sender and includes a report-abuse link. Temporary document copies are deleted after delivery or within 24 hours.

How it works

From Print to WhatsApp in three steps

1. Print to SendFlow

Choose SendFlow from the normal Windows Print menu in any printable application.

2. Confirm the recipient

Preview the PDF, pick a saved contact or enter a WhatsApp number, then send.

3. Delivered

The PDF arrives as a WhatsApp document. Failures produce an email alert (NDR).
