For tradespeople in Tenerife and the Canary Islands
Inselkontor is your office for quotes, invoices, jobs and working hours. Write the quote on your phone, send it on WhatsApp, your customer signs, and one click turns it into an invoice with IGIC.
No card needed. Then €19 a month, cancel any month.
Built for roofers, electricians, plumbers, tilers, painters, carpenters and anyone working solo or with a small crew on the islands.
How it works
Everything hangs off the job: customer, photos, quote, hours and invoice. You always know where each site stands.
The customer calls, you create the job. Site photos, notes and calls go straight in.
Items from your catalogue, measurements with the calculator, IGIC per line. In English, Spanish or German.
Your customer accepts the quote via the link and signs on their phone. No reply? Inselkontor reminds you to follow up after 7 days.
Start the stopwatch on site. Breaks and hourly rate are built in, and the timesheet fills itself.
One click turns the quote into an invoice, hours included. Money in, status set to Paid.
Features
Everything between the building site and your gestoría. On the office computer and on your phone in the van.
Quotes
Line items with quantity, unit, price and discount, sections with subtotals, free text lines. The measurement calculator puts lengths and areas straight into the line. Pull items from your catalogue or from templates and adjust them.
Sending and signing
Send the quote as a link on WhatsApp or by email. Your customer opens it in the browser, no app needed, and accepts it with name and signature. The job moves to Booked by itself.
Invoices
All lines carry over. Hit “Finalise” and the invoice is locked for good. Mistakes get fixed properly with a corrective invoice (factura rectificativa).
Jobs and customers
Status from Enquiry to Paid, photos, notes, calls and tasks. Each morning you see at a glance who to chase and which invoice is still open.
Time tracking
Start the timer on site or add the time later, for a customer or a job, with breaks and hourly rate. Bill open hours with one click, timesheet included.
Your logo, colour and font on quotes and invoices.
First names with your regulars, formal with the property manager. You set the form of address for each customer.

Quick access on site. Leave your phone lying around and Inselkontor locks itself.
A chat in the bottom right answers your questions about using the tool. Even at eleven at night.

FAQ
You pick the IGIC rate for each line, for example 7% or 3%. Quotes and invoices show the net amount, IGIC and total separately. If you're unsure which rate applies to a job, check with your gestoría.
Invoices get a sequential number and are locked when you finalise them. Each invoice is linked to the previous one through a hash chain, and corrections go through a corrective invoice. That way your invoices are prepared for the Verifactu requirements.
You remain responsible for your own tax obligations. Your gestoría can help with the details.
The trial ends automatically. Nothing gets charged, because you haven't entered any payment details. If you want to carry on, pick monthly or yearly and pay by card or SEPA direct debit.
Cancel the monthly plan for the end of any month, the yearly plan for the end of its year. An email to info@inselkontor.com is enough. Afterwards you can still view and export your data.
Yes, any time, under backup in the settings. That way you always have your own copy, and you take everything with you when your plan ends.
