A couple of months ago, my daughter’s school sent me an estimate of her fall tuition. When I looked online just now, I was surprised to see it was $2,800 more than estimated. All the charges and credits looked correct, except one scholarship had been removed. D’s grades were good so I knew that wasn’t the issue. When I called the school, the student aid office said the scholarship WAS showing up on their screen! Somehow, it didn’t get added to the online payment system. So I guess it would have turned out OK eventually, but it is still a little unnerving.
I always review item by item. Things can get easily slipped in…
DS’s school is showing school insurance charges on the statements since waiver requests are still be processed. Details definitely matter when you are dealing with college money.
Check all statements carefully. I was executor for an estate and discovered that the family had paid bills for doctors visits which allegedly occurred AFTER the patient was deceased, and pharmacy bills for prescriptions delivered AFTER death. Family paid them without reading carefully (grief will do that to you).
Auto-billing can render some scary results. YMMV.
Once I was charged for a music lessons when the fee should have been waived. And I’m embarrassed to admit it took me three semesters to catch a room overcharge. But it was nice once I got the refund, and with minimal hassle.
Always check carefully! One of my scholarships my freshmen year didn’t come in for months because a glitch in the system was preventing it to going to me. Turns out that the glitch was because of the apostrophe in my last name.
To follow up romani’s post, 44 yrs ago I lost ALL my merit aid because a student with the same name as me flunked out of my college!
Got all the aid back (double, to compensate) for the spring semester, but lesson learned, I have ALWAYS used my middle initial since!
My husband has a very common first and last name (not John Smith, but similar). When we put our first house on the market, a man by the same name came to look at it! We all agreed it probably wouldn’t be a good idea for the buyer and seller to have the same name.
For some reason my step daughters GSLs and her merit scholarship always posts really late (like after the first payment is due and the semester has started) and I have to keep figuring out what the real amount is we owe-- it is kind of annoying. 
I’ve learned not to look at the bill during July. The school post things, then backs them off, then posts them EXACTLY the same way again. It really drives me crazy so I don’t look until the school has had the month of July to have its fun.
She’s going into her 7th semester and there hasn’t been one that hasn’t had at least 10 ‘corrections’ to the bill. I can’t figure out why they like to post and repost and then make more adjustments. Not so much fun for me at tax time when I’m trying to figure out the actual charges for tuition and fees and the actual grants and scholarships and the billing is a mess.
