AI drafting
AI drafts your unbillable paperwork
Scope documents, meeting summaries, and cost estimates get drafted from your own project notes and drawings. Every draft waits for your review — nothing goes out without you.

Hours to invoice. No timesheet archaeology.
Log time against phases as you go, then turn the unbilled hours into a numbered, professional invoice — downloaded or emailed to your client from the same place the work lives.

The problem
The month-end séance
It's the last day of the month, and you're reconstructing July from your calendar, your sent folder, and your memory. Was the site visit on the 9th or the 16th? Did the DD revisions take four hours or six?
Every hour you can't place is an hour you round down, because underbilling feels safer than defending a number you can't support. That discount comes straight out of the practice — every month.
The fix is boring and it works: log the time when it happens, against the project and phase it belongs to, and let the invoice assemble itself from hours that were never lost.
How it works
Log it. Bill it. Back it up.
01
Log time as you work
An entry is a date, hours, and the phase it belongs to — your rate fills in automatically from your project or firm defaults, and billable stays separate from non-billable.
- Hours logged by project and phase
- Rates filled in from your defaults
- Billable and non-billable kept apart
02
Turn unbilled hours into an invoice
Pick a period — or everything unbilled — and Arcarrow assembles a numbered invoice: labor grouped by phase, reimbursable expenses alongside, as a professional PDF you download or email to your client.
- Labor grouped by phase, never by timesheet row
- Reimbursable expenses on the same invoice
- Numbered PDF — download it or email it
03
Every line has receipts
The invoice draws from the same record as the project's budget view, so the two always agree. Once billed, the hours behind an invoice are locked — the document your client holds keeps matching your books.
- Time entries stand behind every line
- Budget vs. actuals and the invoice always agree
- Billed hours are locked against silent edits

Labor grouped by phase, expenses alongside — assembled from the hours you already logged.
Bill every hour you earned
Arcarrow handles the billable side of the practice in the same place its AI drafts the unbillable side — so the whole month, paid and unpaid, lives in one record.
