Hello! I am looking for consulting services to help me with my Google BigQuery needs for our SaaS app. Specifically, I need external help to generate reports and set up the environment. Each client will have their own data, and we have one table with a few columns for each client. We need to pivot the data by grouping it by year, semester, and quarter. In some cases, we also need to perform simple math with the result of the SUM of two or three columns.

We have an Access Db with a SQL backend which we use as a CRM and customer log that we designed ourselves 17 years ago. This is based on our server and is now reaching its end of life. We therefore want to build a new database using latest tech, probably cloud based, to record our actions with customers, and record time or value for each, with simple easy to use activity and value reporting. The current Db records user, time and date of activity, nature of activity, e.g. sales/ admin etc, client name with details of contacts, records of terms sent, notes, time log (this automatic from start of entry) and so on. Values are not currently linked to invoicing or online accountancy software and having auto invoicing would potentially be an advantage. We are based in Hove, Sussex.
