You bind off at the beginning of each row, knit or purl. You can't bind off at the end of a row, so you always do it at the beginning.
In other words, bind off on the knit side, finish the row. Then bind off on the purl side and finish the row.

Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
