Go to Settings → General Settings → Company details.
Only an Admin user can change the two fields here.
Company name
Use the name your business goes by. This name is also added to your invoices.
Company summary
This is a brief overview of your products and delivery needs. Drivers read this text while viewing your delivery requests. Two to four sentences are usually enough. We recommend covering the following:
What you deliver and how your items are packaged
The weight and volume of a typical load
Which days and hours you usually post routes
Anything special handling or other requirements worth mentioning
Next: setting your payment method.
