Seat-based membership
Invite members up to the purchased seat allowance. Seat quantity is managed through the Business subscription.
GridGap Business
Business includes the full Pro calculation feature set, then adds seats, member invitations, workspace roles, shared projects and organisation branding.
Seats determine how many members can belong to the workspace. The workspace owner controls billing and membership.

A separate working context
Invite members up to the purchased seat allowance. Seat quantity is managed through the Business subscription.
The owner manages billing and retains control of the shared company area.
Authorised members work against the same project and version records rather than maintaining separate copies.
Reports created from workspace projects can carry the organisation's branding.
Member roles
Not every workspace member needs billing control or membership management. Roles keep those responsibilities separate from ordinary project work.
Manages the subscription, seats, members and the highest-level workspace settings.
Supports day-to-day workspace administration without taking ownership of billing.
Creates, edits and calculates shared projects according to the workspace permissions.
Opens shared work for review without the same editing and management permissions.
Shared projects
A business project does not need to live inside one person's account. Authorised workspace members can work from the same project and version records, which makes reviews and handovers cleaner.

Organisation-branded reports
Business reports can use organisation branding rather than personal branding. That makes exported reports more suitable for client discussions, internal review and shared company records.
Prepared in the company workspace with organisation branding.
Who Business is for
Keep preliminary client calculations and report versions available to authorised staff.
Separate shared project work from personal calculations and assign suitable roles.
Manage early planning for several sites from one business workspace.
Build, review and present options without passing files between individual accounts.
The calculation tools are fully available in both. Business adds the workspace, members, roles, shared projects and organisation branding.
