This could be one of two things - but easily fixed.
Regulr was designed so that you told your regulars about it when they were close by or in your venue. So, you need to be within 30km of your outlet to see it in Regulr and you will see the top 45 venues closest to you.
However if no one at all can find you, near or far...
This is usually caused by the address field not quite being entered properly in the Regulr settings.
Head to the posBoss Management Site and click on the Regulr tab.
Select Your Place.
Scroll down to the Outlet Address.
Start entering your address, making sure that you select the green dropdown that appears when you can see the correct one appear (this ties in your location with maps on the Regulr user's phone)
Once selected, give the Regulr app a refresh your (or customer's) phone and you should be good to go!
Get in touch of you have any further issues from there.
