This is great! Being intentional with your upsells is everything. You sell them something they don’t need, they’ll think you’re just trying to make some extra money. Sell them something they do need, and you’re looking out for their best interest.

I think it's a great idea if the subscription starts now and is paid in full before you ever start their project. A subscription would only be a bad idea if they don't fully pay before the project is completed. The approach I've seen work best is when doing take downs, mention that most of your clients opt in for a subscription plan which is 10% of the amount over the next 10 months. (Most of your clients implies this is the popular option, and people like to stick to the popular option). And then follow that by saying they also have the option of paying half by a certain date like August 31st and half after install, or they could just outright pay in full now to get it out of the way. You could also just do 8.33% every month 12 months out of the year, if you want to keep it a non-stop subscription.

This typically happens, Facebook wants to spend most of the budget on what they think will perform best. This is fine, if you spend enough money to dictate if the ad is performing well or not and its doing poorly, then just shut it off then the budget will start getting allocated to other ads, then repeat the process until you have only winners turned on.

@Jean Felix if it’s eating up a lot of the budget but performing well, let it keep eating up the budget. Hitting your KPI targets is all that matters; and eventually it will get ad fatigue at which point you turn it off, and have your next ads ready to test.
