From job to invoice, hours and materials included
You work on site, not behind a desk. You'd rather build a quote on the spot, and afterwards the hours worked and materials used simply need to end up on the invoice.
A quote straight from the job
Build a quote on your phone or tablet on site, and turn it into an invoice with one click once it's approved.
Bill hours through with one click
Log hours worked against the project and invoice them straight through to your client.
Materials on the invoice
Add material costs and project lines to the invoice, so nothing gets forgotten.
Frequently asked questions
Can I make a quote on site?
Yes, from your phone. Once the client agrees it becomes a job, and that job carries the hours and materials to the invoice.
How does extra work reach the invoice?
By putting it on the job sheet while you are standing there and having the client sign. What is signed goes on the bill without argument.
Does reverse-charge VAT work for business clients?
Yes. Choose the reverse-charge scheme and TelMaar charges no VAT and puts the legally required wording on the invoice.

Work it out yourself
- Calculate your hourly rateStart from what you want to keep and work backwards. The dial that matters most is billable hours: you work more hours than you can invoice, and your rate has to carry the unpaid ones.
- Calculate VATConvert an amount excluding VAT to including, or the other way round. Watch the second direction: 21 percent of an amount that already contains the VAT is not the VAT.
- Invoice templateAn invoice has to carry certain details, otherwise your client cannot deduct the VAT. This template puts all of them in place.
- Calculate collection costsIf an invoice stays unpaid you may claim collection costs. How much is set by decree: fixed percentages over brackets, with a minimum of 40 euro and a maximum of 6.775 euro.
