DBPR is an interesting animal. Here is how my day played out . . .
When I initially filed for my HI contractors license, I found that Florida offered a fee waiver for military veterans. Filing fee was $180, and the waiver would take care of that. I remember thinking, “With that savings, I (almost) buy my mold pump.” 
Then today I get an letter in the mail, stating my HI license cannot move forward because I have an application discrepancy: Lack of Licensing Fee Payment.
So here is where I messed. I filled out all hard copies of the application, both licensing and fee waiver, and hand delivered it into DBPR.
SO I call them, and when you get them on the phone, they’re actually pleassent to speak with and seem helpful. I explain the situation, they look at the file, and find both the application and fee waiver are actually there. Cool- we move forward . . . . No!!!
My fee waiver is only a partial waiver because the full waiver is only for people fresh out of the military.
Following conversation goes as follows:
Okay, I get it. So I get a $50 discount.
So can I pay the $130?
Sure can, we take card payment over the phone. Cool can I do that with you now?
No you need to call XYZ.
Call XYZ and pay the fee. Don’t a get a receipt with payments over the phone.
Call DBPR, tell them I paid my fee.
Told to show proof via a payment receipt. 
How do I show you a receipt if you do not provide me one. I paid over the phone . . .
Her response, “I don’t know, I’ll call my supervisor and have to call you back.”
Hindsight 20/20, I should have applied online. She seem so dependent on that system that they don’t seem to know what to do without it. . .
