From job to cash
What gets planned, gets invoiced.
Most companies use four systems to handle one job: a calendar, WhatsApp, a work-order app and bookkeeping software. Hours, materials and revenue disappear between them. TELMAAR is those four systems in one chain.
- 1
Scheduling
Plan the job and put it in the right engineer's calendar.
- 2
Work order on site
Log hours, materials and photos on the phone, in the engineer's own language.
- 3
Customer sign-off
The customer signs on screen and sees exactly what for, VAT included.
- 4
Invoice and books
One tap: the finished job becomes a correct Dutch invoice, straight into your administration.
No double entry, no forgotten hours, no receipts in a shoebox. What gets done gets invoiced, and what gets invoiced lands in your books automatically.
See it in 15 minutesPlanning
The job that ties your calendar to your invoice
Between an appointment and an invoice sits the work itself. Record that as a job and everything you put into it in hours, materials and trips comes out again as an invoice line.
- Appointment becomes a job, address and all
- Hours, materials and receipts in one place
- Your margin visible before you invoice
- Planning board and recurring maintenance

Why switch
Sounds familiar? Then TelMaar is for you
The trade business with three subscriptions
A calendar app, something for work orders and a bookkeeping package that knows neither. The same client entered three times, and at the end of the month working out yourself what still has to be invoiced. In TelMaar the job is the link and the invoice rolls out of it.
The freelancer losing evenings to invoices
Loose Word templates, a spreadsheet for VAT, and figuring out every month what's still outstanding. TelMaar creates and sends invoices in seconds and keeps track of VAT for you.
The SMB with two entities and separate tools
One accounting package per entity, nothing talking to each other. In TelMaar you manage every company in one account, strictly separated yet easy to overview.
The business owner invoicing subscriptions by hand
Copying the same invoices every month and hoping you didn't forget anyone. TelMaar lines them up, a colleague approves, and the rest happens on its own.
From 4.99 a month, everything included
No features locked behind a more expensive plan. You pay for your size, and you can cancel monthly.

Frequently asked questions
Still have questions?
Can I try TelMaar for free?
Yes, you start for free and without a credit card. You upgrade only when you choose to.
Does the invoice follow my language or my client's?
The software speaks nine languages, the document does not. An invoice or quote always goes out in Dutch or English, and you set which of the two per customer. That is deliberate: a Dutch business invoices its customer in Dutch, even if the engineer who did the work uses Polish.
Can I manage multiple entities?
Yes, you link multiple companies to one account, each with its own, strictly separated bookkeeping.
