Whether you have a good savings for your party, or numerous sponsors–the cost of a quinceanera is quite serious. I know from experience how stressful it can be to try to throw an amazing quince on a (super) tight budget. Some of the tips I included below are from experience, and some I wish I had thought of!

Consider having your quince on a day other than Saturday, if possible. Rates for reception halls/venues/ DJs can be significantly cheaper on days other than Saturday.
Does your church have a nice reception room? This can be a very affordable option, and convenient for your guests, too.
Play music from an MP3 player–and you can save alot on the cost of a DJ. There are companies that will come and set up a complete sound system for you to use your MP3 with, and also provide a microphone. Keep in mind you will need someone to make announcements for your event.
If you are buying any party supplies at craft stores like Hobby Lobby, Michaels, or JoAnn Fabrics, make sure to make use of their coupons. You can often find 40-50% off coupons online, or in the store’s mobile phone app.
When shopping for venues, find out what is included. Many reception halls have a stockroom full of goodies that you can use for free. Mirrors, candles, flowers, linens for draping are just some of the things you may have access to.
Balloons, balloons, balloons! Balloons make a huge statement for the price. Even with the cost of renting a helium tank, balloons are a decoration that will make the biggest impact for your money.
DIY favors can be a serious money saver. Homemade treats are not only very affordable, but a big hit with the guests.
Having the quince mass during a time of year when the church already has special decorations is a tip we uncovered on accident. Our quinceanera was held the Saturday following Easter, and the church was still covered in lilies and lilacs. The place was gorgeous with zero effort on our part.
Cupcakes are a more affordable option than a traditional cake. Some grocery store bakeries have better prices than traditional bakeries–and equally delicious goodies.
There is always the question of whether or not to provide alcohol at large parties. One one hand, it is a 15-year old’s party, and serving alcohol adds to your costs. On the other, the guests like to complain if they have to pay for drinks. A compromise is to pay for one type of alcoholic drink–for example, pay for the first keg of beer.
Keep your guest list to those family and friends who matter the most. More guests = more costs. If you are able to reduce your guest list by 10%, that is quite a savings.
A buffet will almost always be cheaper than a sit-down dinner. Buffets can also be a crowd pleaser with the array of options.
Enlist the help of family and friends. Maybe there is a photographer in your family or friend circle, for example, who will cut you a major deal for their services, or may be willing to exchange services with you.
Evaluate what is most important to you. Maybe you have always dreamed of having a chocolate fountain. If money’s tight, look at your plans and see what you can cut in order to be able to afford the fountain. Maybe you will eliminate a videographer, or select less expensive centerpieces.
Don’t hesitate to use something borrowed, if it makes sense. For example, maybe your mom has the perfect shoes to go with your dress. Or your older sister has a tiara from her quinceanera. There is no rule that says everything must be brand new. And of course, it is always eco-friendly to re-use and recycle.
