It is probably less work if you avoid perspective distortion from the outset. Make sure that your camera is pointing squarely towards the face of the painting. (the back of your camera and the canvas should be parallel surfaces).
This assumes that you do paintings on canvas, paper or other "loose material". With e.g. wall or pavement paintings I understand that this may be difficult, perhaps impossible in some cases. Tilt/shift lenses may help, but they are rather expensive and take a bit of learning to use them properly.
