For some odd reason, most of the cheap to mid priced acoustic share a common "feature".
The end user is assumed to use so high action and lots of relief, so the fretwork is very lousy. Or more precisely, the frets are just installed without any leveling or dressing.
On top of that, the bridge and/or the bridge saddle(s) do not usually offer any adjustability.
On some acoustics, You either have to lose the piezo or route the channel deeper in order to keep the saddle to sit upright. Lousy engineering, but that's what we get.
Your best bet is a full setup, DIY or professional, doesn't really matter which one in the end.
If You choose DIY, get yourself at least a fret file and a few practice pieces of material for both the nut and the saddle(s). Plus of course the final saddle and nut material of Your preferred choice.
For me it's bone for acoustics, GraphTech plastic for electrics.
If low action is wanted, most acoustic instruments require constant tweaking as the seasons change, so out sourcing the bi-annual setups can break the bank very quickly. So I do advice going the DIY route
