Diary & Job Scheduling

A diary that fills itself — and stops you double-booking Mrs Jenkins on a Tuesday

The Checker diary is where jobs land, engineers get sent and the day runs itself. Drag a job onto tomorrow, pick an engineer, and the customer gets a “we’re on our way” text without you lifting a finger. When you’re done, the invoice and cert file themselves against the booking.

Every trades business lives or dies by the diary. Miss an appointment, double-book two customers on the same Tuesday morning, forget which engineer’s got the van keys — and suddenly you’re stood in a driveway on the phone to head office instead of doing the job.

Checker gives you a proper trades diary: day, week and month views, colour-coded per engineer, drag-and-drop rescheduling, and every appointment tied straight to the customer record. Book from a quote, from an automated service reminder, or straight from the customer’s file. The diary is the single source of truth for the whole team.

Why engineers love it

Book a job in three taps, tell the customer, send the engineer

Pick a slot, pick an engineer, pick the customer. That’s it. Checker sends the “you’re booked in” text, adds it to the engineer’s phone, and shows travel time between jobs so you’re not sending someone from Leeds to Halifax to Leeds and back again.

What’s on a booking

Everything the engineer needs, before they turn the key

Every appointment is a proper job card — not just a name and a postcode — so nobody rings the office asking “what am I actually doing here?”

Customer & property

Full address, gate code, “dog in kitchen”, tap-to-call and tap-to-navigate.

Job type & notes

Annual service, breakdown, new install — with the boiler make and model already on the card.

Time & duration

Slot length per job type so the diary doesn’t cram three boiler swaps into one afternoon.

Assigned engineer

One tap to reassign. The engineer sees it on their phone straight away.

Linked paperwork

Quote, cert template and invoice all wired to the booking — open the job, fill the form, done.

Status

Booked, on the way, on site, complete. Office sees it live, no ring-round needed.

Why engineers switch

Four things you’ll notice in the first week

No more double-bookings

Every engineer’s diary is on the same screen. If Dave’s already got a 10am, you can see it before you offer the slot to a customer — not after.

Customers stop no-showing

Checker fires a booking confirmation the moment you drop them in the diary, and a reminder the night before. “I forgot you were coming” drops off a cliff.

You squeeze another job into the day

Drag jobs around to build a sensible route instead of criss-crossing town. Most engineers find room for one extra callout a week — that’s a boiler service pure profit.

The office knows without ringing

When the engineer taps “on site” the diary updates in real time. Anyone in the office can answer “where’s Dave?” without picking up the phone.

How jobs land in the diary

Four ways — and you don’t have to type any of them out

  1. Customer accepts a quote. When a quote is accepted, Checker offers to book it straight into the diary — no re-keying.
  2. A service reminder gets booked. Automated reminders go out a year after the last service. Customer clicks “book me in” and the slot lands in the diary.
  3. You add it from the customer file. On the customer record, tap “book a job” and it’s in the diary with all their details already filled in.
  4. Straight into the diary. Tap an empty slot, pick a customer, pick a job type — done.

Running a team

Every engineer on one screen, colour-coded

Toggle to the team view and each engineer gets their own colour column. Drag jobs between engineers to balance the day. See who’s flat-out, who’s got a gap, and who’s on holiday next Thursday. Engineers only see their own column on their phone — less clutter, less confusion.

Calendar sync

Plays nicely with Google, Apple and Outlook

Every engineer’s Checker diary can two-way sync with their personal calendar, so their partner’s Sunday roast stays in the diary next to Monday’s boiler service. Book once, it’s on every device.

FAQ

Frequently asked questions

Can I use the diary on my phone as well as a tablet?

Yes. The diary works on iPhone, iPad and Android, plus any web browser. Book on the tablet in the office, and the engineer sees it on their phone in the van instantly.

Does it stop me double-booking an engineer?

Yes. If a slot’s taken you’ll see it before you drop a second job on top. You can override if you know what you’re doing, but Checker will warn you first.

Does the customer get a text when I book them?

Yes. Booking confirmation on the way in, reminder the night before, “on the way” when the engineer sets off. All optional, all editable.

Can I sync it with Google Calendar or Outlook?

Yes. Two-way sync with Google, Apple and Outlook calendars per engineer. Personal appointments show up in Checker so you don’t book on top of them.

What happens when the job’s done?

The engineer marks it complete, the invoice fires (if you want it to), the cert files itself against the customer, and the next service reminder gets queued up a year out. That’s the whole loop, hands-free.
