Built around how AEC billing actually works
Phase-based billing
Structure your project into phases -- SD, DD, CDs, CA -- and track time and expenses against each. Generate phase invoices individually or combine into a single bill.
Hourly and fixed-fee on the same project
Some phases are T&M, others are lump-sum. Track both on the same project without splitting into separate tools or spreadsheets.
Reimbursable expense tracking
Log travel, printing, consultant fees, and other reimbursables with amounts and categories. They appear automatically as line items on your invoice.
Invoice builder (no extra subscription)
Turn tracked time and expenses into a client-ready invoice in one click. Customize line items, add notes, and download as PDF. No separate accounting tool needed.
Standard AEC project phases
Frequently asked questions
- What billing phases does Time & Mat support?
- You create custom phases to match your contract structure -- Schematic Design, Design Development, Construction Documents, Construction Administration, or any other breakdown. Time and expenses log to the phase, and invoices pull from the phase total.
- Can I mix hourly and fixed-fee work on the same project?
- Yes. Assign some phases as time-and-materials and others as lump-sum fixed-fee. Both appear on the same project and the same invoice.
- Does it handle consultant pass-through expenses?
- Yes. Log any expense with an amount, category, and reimbursable flag. When you generate an invoice, reimbursable expenses appear as line items automatically.
