Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

N/A

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    This plugin didn’t work for me, sent 2 customer support request to Sprout over 72 hours ago and still no reply (I purchased the business license).

    If you use Formidable than you’ll want to check out this integration with Sprout Invoices. I’m the author/developer so you can’t really take my opinion 100%…so why not just download the plugin and try for yourself.
