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
Est. acquisition value
A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay. The range spans more than 10x because wp.org publishes install counts as broad bands, and conversion and price compound on top. Read the midpoint as an order of magnitude, not a valuation.
How we estimate this
Assumptions
- Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product.
- Annual price per customer. $79–$199 a year, typical for Booking & Events plugins rather than this plugin's own pricing.
- Acquisition multiple. 1.5x–2.5x annual revenue, the going range for small WordPress-plugin businesses, compressed because the install trend is declining.
- Install base. 2K–3K active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

An good plugin that’s constantly evolving; there have been many improvements over the years. The support is amazing – they’re quick to respond and always helpful. They came up with a customised solution for me in quick time.

Ik heb meerdere plugins voor boekingen geprobeerd, maar deze is top. Hun ondersteuning is ook geweldig en reageerde erg snel. Zeker het proberen waard. 14 dagen niet goed geld terug is ook een erg fijn gevoel.

We tried a few other appointment/booking plugins before trying Webba. Honestly, those others were a waste of our time -or- they truly helped us appreciate the difference with Webba. Hands down the most feature rich and out-of-the-box PROFESSIONAL booking plugin we found. It has everything you could possibly need, especially if you have a more professional business with multiple services and caveats to what you provide to your customers. We ended up upgrading all the way to the Lifetime Pro license even though we didn’t need all the features beyond Plus because we love this plugin so much; the price difference for the extra features (in case we ever need them) is totally worth it. We found a bug early on in our testing of the plugin and their Support staff responded lighting fast and was quick to locate and patch the bug, issuing an updated version within mere days! A truly professional plug-in from a truly professional company! Thanks, Webba. We’re going to love working with you for years to come. 🙂

Been playing around with the free version and even though I’m not on the pro version the support has been amazing. I definitely upgrade when I start my business as I know the support will be there. Great job guys!

I tried multiple plugins for bookings but this one has been the best so far. Their support is great as well and was very quick to respond. Definitely worth a try.
