Its up to you honestly. its not mandatory however if they go above and beyond i would tip a little but but not for every single vendor thats a lot. i am also gonna write amazing reviews online for all my vendors
I've been told that if they own the business you do not need to tip as they set the prices. If they are an employee or have staff that don't own the business you should tip.
Honestly it's up to you, if they went above and beyond and you want to thank them with a tip then go for it. Our photographer has been awesome and I intend to give her a thank you gift that is a little more personal than cash.
I also agree with Gloria. The other thing to check is your contract/quote because sometimes they have already added it in. I know the gratuity for our limo and the hair stylists are already included in the contract.
We're tipping limo, DJ, photographers/videographers, hair and make up artists ...and I think thats it?
I'm with Gloria on this. If they are their own company (so like an officiant or DJ) then they set their own prices so tips aren't needed. If it's like a food service then it's nice to tip the servers just like you would a waitress at a restaurant.
We didn't do it by % though, we just tipped servers like $20/each, bartenders $50/each, officiant - even though he set his own prices - tipped him for doing a great job even in the POURING rain outside We just tipped with cash from the presentation we got and tipped according to how we felt they did.
