Frequently Asked Questions

How does the bonus bar tab work?

What is the bonus bar tab?
At Partystar we connect you directly to venues for function enquiries without charging any commission on your booking (unlike our competitors). Since venues aren't paying 10-15% of your booking in commission, they can afford to offer you a bonus bar tab. We think that's a win.
How do I qualify for the bonus bar tab?
The bar tab is included automatically if it's listed on the venue's function page. To activate it, simply book your function through Partystar and meet the venue's specified requirements (hire charge, minimum spend, or, minimum guests).
Is the bonus bar tab available for every venue?
Not all venues offer a bonus bar tab, but most do. If the venue offers it, it will be clearly indicated in their listing.
When and how is the bonus bar tab applied?
Once your booking is confirmed, the venue will add the bar tab to your overall bar tab. You can use it for drinks on the night.
What if I don't meet the minimum requirements?
The bar tab is only provided if the venue's specified requirements are fulfilled (paying the hire charge, meeting the minimum spend, and meeting the minimum guest numbers). If not, the booking may still proceed, but without the bonus.
