He was talking about gross profit margins. Just do the math:
revenues ($2,747,611) divided by gross profit ($1,615,398) = 58.7%.
That's a gross margin figure.
The net profit margin is revenues divided by net income...
Just clarifying.
Most companies have a decent looking gross margin but a FAR LOWER net profit margin. SINO's net profit margin is ENORMOUS! :-)
And that's what we mean by a really impressive bottom line!
