New pricing for G Suite Basic and Business Editions is taken from the article written by David Thacker, Vice President of Product Management, G Suite (17 Jan 2019)

Over the last ten years, G Suite has grown to provide more tools, functionality and value to help businesses transform the way they work. The one thing that hasn't changed over this time is price. 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.

For existing G Suite Basic or Business edition customers on the Flexible Plan, the new list prices will go into effect on April 2, 2019. For customers on the Annual Plan, the new prices will go into effect the first time their plan renews on or after April 2, 2019. These changes will not impact current contracts or any renewal events prior to April 2, 2019.

Additionally, for those Basic and Business Edition customers who receive their bill from Google, we’ll send an email with details specific to their domains no later than February 28, 2019.
