Project Management & Time Tracking

General-purpose time-tracking and invoicing tool, not architecture-specific, that many small firms use to bill clients and track project profitability.

The most solo-friendly and cheapest entry point, free for one user, but it's just time-and-billing -- you'll outgrow it for true project financials and proposals as you scale.

Cloud accounting and invoicing platform for freelancers and service businesses, with built-in time tracking, retainer billing, and project profitability reports.

Built-in time tracking makes FreshBooks a single-tool billing solution for a sole-prop A/E -- log hours per project and convert to invoices without a separate time-tracking app; the feature set is narrower than Monograph or BQE CORE but covers the core billing use case at a lower price.

Firm management software that combines project budgeting, time tracking, staff planning, and invoicing built specifically for architecture and engineering practices.

Solo-friendly and the most approachable purpose-built option for a firm of one, though at ~$25-45/user/month you're paying for capabilities a single architect may only partially use.

All-in-one freelancer business platform with contracts, invoicing, time tracking, expense management, and a CRM, with an MCP server for AI agent integration.

Solid time tracking included at no extra cost -- Bonsai's timer links hours to projects and converts them directly to invoice line items, covering the core project-time workflow a sole practitioner needs without a separate tool like Harvest.

All-in-one platform for project accounting, billing, time tracking, and resource planning built by and for architecture and engineering firms.

Capable but heavier than a one-person shop needs, and the sales-call-only pricing plus learning curve make it overkill unless you're already scaling past a couple of people.

AI-assisted resource planning and capacity forecasting platform used by project-based firms including A/E practices to allocate people across projects.

Overkill for one person -- resource planning across a team is its whole point, so a solo architect has little to allocate and would pay sales-call pricing for capacity they don't need.

Project-based ERP combining accounting, billing, scheduling, and resource management for small and mid-sized architecture and engineering firms.

Enterprise-grade ERP that is overkill and overpriced for a firm of one -- skip unless you're scaling toward a real back-office with multiple staff and dedicated bookkeeping.

Cloud practice and project management tool for architects and engineers covering scheduling, time tracking, invoicing, and month-by-month financial forecasting.

Solo-friendly in intent and A/E-specific, but its smaller track record and undisclosed pricing mean a firm of one should trial it carefully before committing.
