Once you meet the Arkansas economic nexus threshold, you must register, collect the correct Arkansas sales tax rate on all taxable sales, file regular returns (frequency depends on your sales volume — monthly, quarterly, or annually), and remit the collected tax by each due date. Retroactive liability can apply to sales made after you crossed the threshold but before you registered, so acting quickly after exceeding the threshold limits your exposure.
