DKalendar is the engineers-by-days wall planner your office already thinks in — made live. The office plans the week, engineers and drivers work from their phones, and everyone looks at the same board.
Everything a small contractor juggles across a spreadsheet, a group chat and a folder of Word forms — in one place, kept in sync for everyone.
Engineers down the side, days across the top, every visit a chip colour-coded by category, with its important notes and reminders visible straight away. Drag to move, copy to another engineer, filter by team. Every open screen updates within seconds.
Every visit, delivery, photo, checklist, note, update and document for a job on a single card — and it's the same card the engineers open on site. Reached from the calendar, the jobs list or dispatch, always the same record.
Today's jobs with the site address, contacts and related documents. Photo checklists, progress and daily updates from site — and a request to the office when something's missing. Copes with patchy signal.
Deliveries are added by managers straight from the calendar; the Dispatch view arranges the kit: dispatch dates, the driver's run, proof-of-delivery photos and delivery notes — and a warning when a visit is booked with no kit on its way.
Planned preventive maintenance per site with its frequency and an all-sites view of what's due — and a maintenance job card with every update, report, document and photo: call-outs, materials and the full job history in one place.
Quick reports on what's already in the system — job days by category, maintenance and call-out days, holidays and sick days, wasted visits, who was free and when — each number drilling down to the jobs behind it.
The same record travels from the office to the site and back, so nobody re-types anything and nothing gets lost in a chat thread.
A chip lands on the board, on the engineer's phone and in the weekly instruction email. The office attaches the drawings and documents to the job, and kit is ordered against the same job, so dispatch already knows what's going where.
Whoever is booked on the job automatically gets its card on their phone — address, contacts, kit and documents. Photos, the checklist and the day's update go straight onto that card. A missing part becomes a request the office sees immediately.
Overdue updates and unsigned deliveries are chased from one list. Progress, proofs and history are on the card when the client asks — and in the reports at month end.
Teams of ten to fifty engineers running multi-day, phased installs on commercial and construction sites — with a maintenance book on the side. If you plan your jobs in a spreadsheet, this is that spreadsheet — alive, and better.
Most field-service tools are built around hourly appointments and show you availability numbers. DKalendar is built around whole-day site work and shows you the actual work: every engineer's week, the kit behind it, the notes and reminders, and what's on stop — readable in one scroll.
And the job card the office works from is the one the engineer opens on site: every visit, delivery, document, photo and update, with the full history — one record, no re-typing.
Deliberately not included: quoting, invoicing and payments. DKalendar does the planning and the site record, and stays out of the way of the tools you already use for the rest.
