Just saw this post on G-Suite’s website:
Today, we are announcing two incremental list price updates to reflect this value. Starting on April 2, 2019*, G Suite Basic Edition will increase by $1 (from $5 to $6 per user/month) and G Suite Business Edition will increase by $2 (from $10 to $12 per user/month), or the local currency equivalent where applicable. These increases will apply globally with local market adjustments for certain regions. Pricing for G Suite Enterprise Edition customers will not change.
