9 languages in the app, Dutch invoice

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. 1

    Scheduling

    Plan the job and put it in the right engineer's calendar.

  2. 2

    Work order on site

    Log hours, materials and photos on the phone, in the engineer's own language.

  3. 3

    Customer sign-off

    The customer signs on screen and sees exactly what for, VAT included.

  4. 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 minutes

Planning

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

Built for your trade

Recognise your business

TELMAAR is built for companies that work on location. Pick your trade and see exactly what the working day looks like: from first appointment to paid invoice.

Trust & security

Financial data deserves more than a password

Two-factor authentication

Required for everyone with a financial role, no exceptions.

Encrypted bank details

Account details are stored encrypted and never visible in plain text.

Full audit trail

Every change to invoices and bookings is logged, including who and when.

EU data center

Your data lives in Frankfurt, within the European Union.

Rights per company

Anyone without access to an administration does not get that data, not even by a detour.

Four-eyes principle

Above your threshold a second person looks along. Bank details always.

Sessions under control

See where you are logged in and revoke a session. A role change ends them at once.

Access and erasure

Handle GDPR requests. Financial records stay, due to the retention obligation.

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.
