Accretion is one of the most important astrophysical phenomena which is crucial to our understanding of the formation and evolution of young stellar objects, cataclysmic variables, X-ray binaries, or ultraluminous X-ray sources. Cataclysmic variables are particularly important in our understanding of accretion models, as they exist in binaries with a wide range of mass transfer rates. Moreover, currently, there are hundreds of nearby cataclysmic variables that can be studied in detail. Thanks to the high cadence of TESS data we can have a complete look into the variability of these objects that is related to accretion. In this talk, I will discuss observations of few selected objects that are the most interesting for our understanding of accretion out of the hundreds of cataclysmic variables observed with TESS. In particular, I will showcase objects that have tilted accretion discs or changing accretion states.
