How to Bill Clients Based on Task Time

Freelancers and consultants: Stop losing money on unbilled time. Here's how to track every billable minute using TaskRio.

The Freelancer's Dilemma

You work: 6 hours on client project
You bill: 4 hours
You lose: ₹4,000 (or $50)

Why? Because you forgot to track:

  • • That 30-min client call

  • • Email back-and-forth (1 hour)

  • • Small revisions (30 min)
  • Over a month: ₹40,000 lost ($500+)
    Over a year: ₹4.8L lost ($6,000+)

    Time to fix this.

    The WhatsApp Time Tracking System

    Why Track in WhatsApp?

    Traditional time trackers suck because:

  • • Separate app (you forget to open it)

  • • Complex interface (too much friction)

  • • Desktop only (you work on phone too)

  • • Doesn't integrate with communication
  • WhatsApp wins:

  • • Already open all day

  • • Start/stop in 2 seconds

  • • Works everywhere

  • • Tasks + time in one place
  • Setup (5 minutes)

    1. Add TaskRio to WhatsApp
    Message: +91 99250 37581

    2. Create client groups
    One group per client:

  • • "Client A - Projects"

  • • "Client B - Consulting"

  • • "Client C - Design Work"
  • 3. Enable time tracking


    @TaskRio enable time tracking

    Done. You're ready.

    Basic Time Tracking

    Start Timer When You Begin Work

    You: Start working on client's website

    Type:


    @TaskRio start timer: fixing homepage layout

    TaskRio: "Timer started ⏱️"

    That's it. Keep working.

    Stop Timer When You're Done

    You: Finish the work, take break

    Type:


    @TaskRio stop timer

    TaskRio: "Timer stopped. Duration: 2 hours 15 minutes"

    Time automatically logged.

    Manual Time Entry

    Forgot to start timer? No problem.


    @TaskRio log 3 hours for client meeting yesterday
    @TaskRio worked 1.5 hours on logo design this morning
    @TaskRio add 45 minutes to proposal writing

    Advanced Time Tracking

    Billable vs Non-Billable

    Billable work:


    @TaskRio start billable timer: client presentation prep

    Non-billable:


    @TaskRio start non-billable timer: administrative work

    Why separate?

  • • Track total work vs client billing

  • • Know your real hourly rate

  • • Don't overbill clients
  • Task-Based Time Tracking

    Create task, track time:


    @TaskRio Design 3 logo variations by Friday
    T42 start timer
    [work for 2 hours]
    T42 stop timer
    T42 done

    Task shows:

  • • Total time spent: 2 hours

  • • Billable amount: ₹4,000

  • • Status: Complete
  • Multiple Clients Same Day

    Morning - Client A:


    @TaskRio start timer: ClientA website updates
    [work 2 hours]
    @TaskRio stop timer

    Afternoon - Client B:


    @TaskRio start timer: ClientB proposal writing
    [work 3 hours]
    @TaskRio stop timer

    Evening - Client C:


    @TaskRio start timer: ClientC design revisions
    [work 1 hour]
    @TaskRio stop timer

    Each client group tracks separately.

  • Track revisions:

    T25 stop timer

    @TaskRio Revision round 2

  • • Revisions (3 hours): ₹4,500

  • Total: ₹19,500

    Client: Monthly retainer + hourly overage

    Agreement:

  • • ₹50,000/month for 20 hours

  • • ₹3,000/hour beyond that
  • Track monthly:


    Week 1: 6 hours
    Week 2: 8 hours
    Week 3: 4 hours
    Week 4: 7 hours
    Total: 25 hours

    Invoice:

  • • Retainer (20 hours): ₹50,000

  • • Overage (5 hours): ₹15,000

  • Total: ₹65,000
  • Fair to both sides.

    Best Practices

    1. Start Timer Immediately

    Don't wait. When you start work, start timer.

    Bad: "I'll remember to log it later"
    Good: Start timer first, then work

    2. Be Specific with Task Descriptions

    Bad: "working on stuff"
    Good: "Homepage responsive mobile layout"

    Why? Client sees line items on invoice.

    3. Track Everything

  • • Client calls

  • • Emails (if substantial)

  • • Revisions

  • • Meetings

  • • Research
  • If it's for client, it's billable.

    4. Round Up (Within Reason)

    Worked 1 hour 47 minutes?


    @TaskRio log 2 hours

    Fair rounding. Don't nickel-and-dime yourself.

    5. Review Daily

    End of each day:

    Make sure nothing missing.

    Handling Client Objections

    "Why did this take so long?"

    Show task breakdown:


    Homepage design: 4 hours
  • • Initial mockup: 2 hours

  • • Client feedback review: 30 min

  • • Revisions round 1: 1 hour

  • • Final adjustments: 30 min

  • Transparent = trust.

    "Can you give me a discount?"

    Know your numbers:


    @TaskRio time summary

    Shows:

  • • Actual time spent

  • • Your hourly rate

  • • Market rates
  • Stand firm or negotiate from facts.

    "I thought it was included"

    Refer to time logs:

    "Per our agreement, initial design was included. These 3 hours are additional revisions based on new requirements."

    Data wins arguments.
