Inspirations to Build From

Build a hierarchical project sheet like Smartsheet

Row hierarchies, formulas, and Gantt views for teams who think in spreadsheets but need approvals and cross-sheet reporting.

Modules, workflows, and the page editor

Your container when you outgrow the visual tools

Data model

Build these as modules and custom fields — no schema migration, no code required to add a field or a relationship:

  • Hierarchical rows (parent/child)
  • Formula fields
  • Approval-request records
  • Cross-sheet report definitions

Pages

Compose these in the page editor from data-bound blocks, or start from a template pack and customize from there:

  • Grid with row hierarchy
  • Gantt view
  • Form intake
  • Cross-sheet report dashboard

Automation: a form-driven approval

Model this as a workflow — each bullet is naturally one step, run automatically on the trigger:

  1. A form submission creates a row
  2. An approval request is generated and routed to the right approver
  3. On approval, the row's status updates and dependent rows are notified
  4. The change is recorded in cell-level history

Market and pricing

Read these as directional

Market sizes and competitor prices move constantly, and published figures vary widely by source and methodology. Treat the numbers below as order-of-magnitude orientation for deciding what to build — not as researched inputs for a pitch deck or a pricing page. Verify current figures before either.

Where incumbents priceGrid-based enterprise project tools price at roughly $9–35/seat/mo, with enterprise agreements far above that.
Suggested entry pricing$20–50/seat/mo, with enterprise licenses negotiated annually

Building in more value

Where the margin actually lives — the upgrades and add-ons worth designing in from the start rather than bolting on later:

  • Approval workflows and cell-level history as the compliance tier — regulated buyers pay for provable history
  • Cross-sheet reporting and portfolio rollups gated to management seats
  • Resource management and capacity planning as an add-on
  • Form intake volume tiers for high-submission customers
  • Annual enterprise agreements with implementation services attached

The BuildWithHQ angle

Build this after your grid and formula components are mature — the specialized part of this product is calculation depth, not data modeling, and it's worth getting the formula engine right before promising it.
