Field Service Business Checklist: Before, During, and After Every Job

Most job problems aren't caused by bad technical work — they're caused by a missed step somewhere in the process around the work. A simple checklist, used consistently, catches the small gaps before they become a customer complaint or an unpaid invoice.

Before the job

Confirm the appointment 24 hours ahead. A quick text or call cuts no-shows and last-minute cancellations significantly, and gives you time to fill the slot if the customer needs to reschedule.
Review the scope and any customer notes. Know what was requested, any access instructions (gate codes, pets, parking), and whether this is a first-time or repeat customer before arriving.
Check the truck is stocked for the job type. A quick mental or written inventory check against the expected job avoids a mid-job supply-house run.
Confirm pricing or estimate range with the customer if it hasn't already been sent, so there's no surprise when the invoice arrives.

During the job

Take before photos, especially for anything involving existing damage, so there's a record if a dispute comes up later about what condition things were in beforehand.
Get approval before expanding scope. If the job turns out bigger than quoted, get a quick verbal or text confirmation on the added cost before continuing, not after.
Log materials and time as you go, not from memory at the end of the day. A part grabbed off the truck at 10 a.m. is easy to forget by 4 p.m. when six other jobs have happened in between.
Take after photos, both for your own record and as something you can send the customer showing the completed work.

After the job

Walk the customer through what was done. Even a two-minute explanation — what the problem was, what was fixed, anything to watch for — reduces follow-up confusion calls significantly.
Send the invoice immediately, not days later. Invoices sent same-day get paid faster on average than ones sent even 48 hours after the job, simply because the work is still fresh in the customer's mind.
Note anything for next time in the customer's file — equipment model numbers, access details, preferences — so the next visit starts from more information than the last one did.
Follow up within 48 hours to confirm everything's working as expected. This step alone catches a meaningful share of issues before they become a negative review or a callback.
Ask about recurring service or the next logical job, if relevant, while the experience is still positive in the customer's mind.

Why a written checklist beats "we all know what to do"

Every technician thinks they remember all these steps — and most of the time they do, until a busy day, a difficult customer, or a rushed schedule causes one to slip. A physical or digital checklist attached to each job removes the reliance on memory under pressure, which is exactly when steps get skipped.

Build it into the job record, not a separate piece of paper

A checklist that lives on a clipboard in the truck gets lost, left behind, or ignored once it's inconvenient. Attaching the same before/during/after steps directly to each job in whatever system tracks scheduling and invoicing means the checklist travels with the job automatically — which is part of why job management tools like ServiQ let you build these steps into the job workflow itself rather than trusting a separate paper process to keep up.
