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.

See it in 15 minutesThe language bridge
Your engineer works in Polish. Your books stay Dutch.
This is what sets us apart from every other package. Everyone in your company picks their own language, and still there is only one set of books: the Dutch one. Amounts, VAT rates, article codes, units and dates never change because of a translation.

The engineer on site
Working in your own language. Your customer never notices.
On site only one thing counts: that the work is recorded properly. That works better in the language someone actually speaks. The job sheet that comes out is Dutch, with the hours, the materials and the VAT you can rely on.
Next job and navigation
The app opens on the next job, with the address, the contact and navigation one tap away.
Hours, materials and photos
Log the time worked, pick materials from the van stock and record the situation with photos.
The customer's signature
The customer signs on the screen. The job sheet is done and sits with the job right away.
Offline with sync
In a crawl space or a basement the app simply keeps working. As soon as there is a signal, everything follows.
The same job sheet, three languages
These are real screens from the app, not mock-ups.

Customers speak
Businesses that work with it every day
From web agency to roofer: this is what business owners say who moved their planning, invoices and bookkeeping into TelMaar.
On a renovation, hours, material and extra work get mixed up. Now everything sits on the job and I see my margin before I invoice. The customer signs on the phone and the invoice is right the first time.
A veranda goes from quote to installation to invoice, and every step used to cost us separate work. Now the quote becomes the job and the job becomes the invoice. My fitters see their day on the phone and I see what comes in.
In maternity care you want to be busy with families, not paperwork. Hours are logged on the phone, the invoice follows by itself and reminders go out without me chasing them. That gives peace of mind.
We lay floors and work with a lot of quotes. In TelMaar the customer accepts the quote digitally in the portal, the job is scheduled immediately and after handover the invoice is there with one click. It really saves evenings.
For security installations the history belongs with the object. Every panel of ours has a QR sticker: scan it and the engineer sees what was done before. Service contracts renew themselves and the SLA sets the priority.
Emergency roof work cannot be planned, but the admin afterwards can. The roofer takes photos, the customer signs on the roof on the phone and the invoice goes out the same afternoon. Offline in a crawl space or on the roof: it just keeps working.
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.

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.
