Online appointment booking for trade businesses: refill cancelled on-site slots automatically
Customers book measuring, maintenance or installation themselves on your own company website. When someone cancels, TerminJet offers the free on-site slot to the waitlist via WhatsApp right away, instead of leaving it as idle time in the calendar.
A cancelled on-site appointment on Wednesday
A customer cancels the morning measuring appointment at short notice. Here is how the day looks with and without TerminJet.
- The cancellation lands on voicemail, nobody notices it until the drive out.
- The technician drives to an empty address or is suddenly left without a job.
- The free morning stays unused, the day's utilisation tips over.
- Waiting prospects from the previous week are not actively contacted.
- There is no full online booking at all, everything runs by phone through the office.
- The cancellation immediately triggers a request to the consent-based waitlist.
- Those waiting are offered the slot by WhatsApp or SMS and confirm with one click.
- The free morning is refilled before dispatch even has to step in.
- Address, photos and service type of the new booking come along directly.
- The office no longer coordinates by phone, it sees the confirmed appointment in the calendar.
A lean booking front end, not a second industry software
Full plumbing or trade ERP suites can handle inventory, invoicing and payroll, but online booking and slot refilling are often just a side feature there. TerminJet does exactly this one part right: accepting appointments and refilling cancelled on-site slots. It does not replace your office software, it takes appointment coordination off its hands.
Features that fit field work
Customer intake with photo upload
Address, description, urgency and photos of the damage come along directly in the booking flow. You assess effort and materials before anyone sets off.
Travel zones and travel-time buffers
TerminJet takes your service areas into account and plans in travel time, so appointments in the same area are sensibly bundled and the day's plan stays realistic.
Automatic slot refilling
If an on-site appointment falls through, the engine asks the consent-based waitlist by WhatsApp or SMS and refills the slot without office phone calls.
Appointment types per trade
Measuring, maintenance, installation, repair and on-site consultation are set up as separate appointment types with their own duration and their own buffer.
Reminders against no-shows
Automatic reminders by WhatsApp and SMS reduce short-notice cancellations before the technician drives out in vain.
White-label on your domain
The booking flow runs in your design on your own company website. No third-party portal, no commission, no shared SaaS tenant.
From template to online booking for your on-site visit
- Schritt 01
Adapt the template to your trade
We configure appointment types like measuring, maintenance and installation, your travel zones, buffers and the rebooking rules to fit plumbing, electrical or painting.
- Schritt 02
Build it into your website
The booking flow with photo upload and address request is embedded directly into your website as an intake form in your design and feeds the engine.
- Schritt 03
Book and refill automatically
Customers book themselves around the clock. When someone cancels, TerminJet offers the slot to the waitlist and refills it, without the office making a single call.
A focused booking front end instead of large industry software
A full trade or plumbing suite is built for inventory, invoicing and accounting. TerminJet covers online booking and slot refilling specifically and runs alongside it.

Frequently asked questions
Does TerminJet replace our trade or plumbing software?
No. TerminJet is not an ERP. It handles online appointment booking and the refilling of cancelled on-site slots specifically, and runs alongside your existing office and billing software.
How are cancelled on-site appointments refilled?
When someone cancels or does not show up, the engine automatically offers the freed slot to the consent-based waitlist, by WhatsApp or SMS. Whoever confirms first gets the appointment, without your office having to make any calls.
Is this also suitable for electrical, painting or carpentry, not just plumbing?
Yes. The trade template is designed for on-site service, not for a single trade. We set up appointment types, durations, travel zones and buffers per business, whether plumbing, electrical, painting or carpentry.
Can customers send photos and the address in advance?
Yes. Address, description, urgency and a photo upload are part of the booking flow. That way you assess effort and materials before a technician sets off.
Do customers need a third-party portal?
No. TerminJet runs white-label in your design on your own company website. No intermediary platform, no commission, no shared tenant. It is your own instance.
Who sets this up and where is the data stored?
We, as a digital agency in Germany, configure the template, build the intake form into your website and maintain the system on an ongoing basis. Hosting is in the EU at Hetzner, and personal data is AES-256 encrypted.
How your customers book an on-site appointment
This is the embedded intake form that also runs on your website and feeds the engine directly. Book a test appointment and see which data comes in.
