good idea to keep it as a separate account. My office has a problem if it sees transactions during the year apart from t/f 400k to my daily account when it's available and back again when it's due !
I once went under 800k by 49 BAHT for a few MINUTES and had to start the process from new which included a new visa from Malaysia. Very expensive mistake.
Not until I questioned several times did my local office admit it is 2 months prior, even though they had given me an out dated hand-out the first time I questioned it, so be prepared.
Fortunately for you they seem strict on the 800k baht minimum as I once had to do a visa-run and start again over 49 baht shortfall for a couple of minutes !
