Service Call Dispatch Board with Technician Day Sheets

Service Call Dispatch Board is an offline app (one HTML file in a zip) for the person who answers the phone at a small repair or maintenance company. Every call becomes a job with a customer, an address, a problem and a priority. You assign it to a technician for a date and time, and the app checks that the technician is free and not over their limit for the day. A board shows what is new, assigned, on the way, in progress and done, and each technician gets a printable day sheet.

The problem it removes: Jobs are sent to technicians by chat. Two jobs land on the same technician at the same hour, an urgent call sits unassigned, yesterday's job is never closed, and customers phone to ask where the technician is. This app gives every call a status and an owner, and refuses a double booking.

What is inside:

• Dispatch page: calls to assign, urgent calls still open, jobs left open from earlier days, return visits, and each technician's load today
• A call needs a technician and a date before it can move past New, and a technician cannot be booked for overlapping times on the same day
• A daily job limit per technician: the app refuses the job that would go over it
• Board with seven columns from New to Done, and a calendar of booked jobs
• Call notes with date and time: customer phoned, part ordered, customer not home
• Day sheets generated for today or tomorrow, with the jobs, estimated minutes and the cash the technician should hand in
• Printable day sheet per technician and a job slip for the customer to sign
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: small AC, plumbing, electrical and general repair companies, facility service teams and dispatchers who take calls by phone or WhatsApp and send two to ten technicians out each day.

What it is NOT: It does not track vehicles on a map, work out routes, send messages by itself or take payments. It does not keep stock or spare parts. Technicians use their own phones or the printed sheet: there is no technician login and no sync between devices. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (172 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1008 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
