From Hours Tracked to Invoice Sent: The Complete Automation Guide

If you're a freelancer or agency billing by the hour, you've lived this nightmare: it's the end of the month, you have hours spread across 4 clients in 3 projects, and you're manually copying numbers into a spreadsheet to build an invoice. It takes 2 hours and you always miss something.

There's a better way.

The True Cost of Manual Billing

Studies show freelancers lose an average of 5-8 hours per month on administrative billing tasks. At €80/hour, that's €400-640 per month you're giving away — €4,800-7,680 per year.

More critically, manual billing leads to errors: undercharging, missed hours, wrong tax rates. One missed 3-hour session per month costs you €240 in lost revenue.

Arbeitly's Time-to-Invoice Workflow

Step 1: Log Time as You Work

Open any job or project in Arbeitly and start the timer. Work, then stop the timer. That's it. Your hours are logged with the exact start/stop time, which client, which project, and any notes.

Alternatively, log time in bulk at the end of the day — add multiple entries with duration, description, and billable flag.

Step 2: Review Your Billable Hours

At the end of any billing period, navigate to Time → Billable Summary. You'll see a clean breakdown:

• Total hours per client
• Billable vs non-billable split
• Effective rate per project
• Unbilled hours alert (never forget a session again)

Step 3: One-Click Invoice Generation

Select the client, choose your time entries, and click "Generate Invoice." Arbeitly automatically:

• Groups time entries by project and task
• Applies your hourly rate (or fixed rate per project)
• Calculates totals, VAT, and any applicable discounts
• Numbers the invoice sequentially
• Applies your payment terms and bank details

You review, make any edits, and send. The whole process takes under 3 minutes.

Step 4: Track Payment Automatically

Once sent, the invoice lives in your dashboard. You see exactly who owes what. When payment arrives, mark it paid (or connect Stripe for automatic detection). Arbeitly calculates your average payment time per client — useful for spotting slow payers early.

Advanced: Team Billing

Running a small agency? Assign time entries to team members (resources), track utilization rates, and generate consolidated client invoices that detail individual contributor hours. Your clients get full transparency; you get one invoice to manage.
