Assignment check: is this job worth it?

Clients & sales

Enter price, hours and costs and see what a job leaves you per hour, before you say yes.

Revenue€ 18,420Outstanding€ 4,235Costs€ 2,310
Assignment checkIs a job worth it? Check before you say yes
01

What is it?

Assignment check works a fixed price or hourly rate through to what you realistically keep, allowing for admin hours, extra work and project costs.

02

Who is it for?

For freelancers with a Dutch business who want to assess a new job or quote before committing.

03

What problem does it solve?

A nice number on paper disappoints once you count the hours for emails, revisions and extra requests. Assignment check makes that visible before you start.

What you get

01

What you keep per hour

The result is an amount per hour after costs and a share to set aside, not revenue per hour on paper.

You keep per hour€ 48.70Accepted

Allows for extra work

How it works in SmartWerk

  1. 1

    Pick a starting point

    Start from an example, such as a fixed website project or an hourly rate, and adjust every figure.

  2. 2

    Enter your numbers

    Price, billable hours, admin hours, extra scope and costs. If you use the small-business scheme (KOR), switch it on.

  3. 3

    Read the result

    See what you keep per hour, the project turnover, what is left after costs and what to set aside.

  4. 4

    Turn it into a quote

    If the price works, continue from Assignment check to a quote.

What you can do

Assignment check comes before the quote: you assess the job, make a quote and then record it in a contract.

  • This project tab

    Assess one job: fixed price or hourly rate, hours, buffer and costs.

  • My hourly rate tab

    Work out the minimum hourly rate from what you want to keep per month, your yearly costs, hours per week and weeks off.

  • Suggested price

    See the price from which you avoid a loss on paper and apply it in one click.

  • Comparison with your own figures

    Compare with your average from paid invoices, once there is enough data.

  • Examples to start from

    Ready-made scenarios that you adjust yourself.

Frequently asked questions

Is the result tax advice?

No. The figures are indicative. Talk to your bookkeeper before you decide.

Can I work through both a fixed price and an hourly rate?

Yes. You pick a fixed price or an hourly rate for each calculation.

Can I make a quote from the result?

Yes. From Assignment check you can continue to creating a quote.

Can I have my minimum hourly rate calculated?

Yes. You enter what you want to keep per month, your yearly costs, your hours per week and your holiday weeks; Assignment check calculates the minimum hourly rate.

What it does not do

  • It is a planning aid, not tax advice: the tax set-aside is a simplified estimate.
  • Assignment check is meant for business owners with a Dutch business and is not shown for sellers in Belgium or Germany.
