You have to be an Individual, HUF or a Partnership Firm (not LLP) to be able to opt for presumptive taxation u/s 44AD. You can also not claim any deduction under Section 10A,10AA, 10B, 10BA which deal with deductions claimed for units in SEZ, FTZ, 100% EOU etc. You also cannot claim deduction under chapter VIA, this includes your 80C investment limit of Rs. 100000/-.
All businesses other than plying, leasing hiring of good carriages, any profession, commission agents, or any other agents, are allowed to opt for 44AD. So coffee curing will also be eligible business.
The extent of your fixed assets will not hamper the option. You can still opt for 44AD.
