We also needed a custom feature for our company's Quickbooks accounting and I must say it was a welcome treat to have someone listen to our need come up with a solution and develop it at a very fare price.
If I could I would give this component a 10+ rating it really saved us and opened the doors to new opportunities.
Had some problems with layout and getting things to work right Dylan went above and beyond even rewrote some files for me to make everything work.
what was better it wasn't days it was hours and stuck with me responding immediately till all was up and running.
truly top notch highly recommend this extension
