In our Project packages we always offer a support period of around 1 to 2 weeks once the store has gone live. If any bugs or questions come up during this period will be quick to offer assistance. Once that period comes to an end we recommend you as a merchant sign up for a Support package. The Support package offers quick answers on Shopify matters, speedy bug fixing, but perhaps most importantly, gives you ease of mind knowing that coi will be there if sh*t hits the fan.
