# Service and maintenance companies

_Technicians out on the road, job sheets, and clients asking what was done last month._

**Responde a:** technician job sheets · maintenance company documentation · evidencing service delivered to the client · maintenance contracts and visits

A maintenance company sells something hard to show: visits that happened, checks that were carried out, and breakdowns that never occurred. All its documentation exists to evidence work that, done well, is invisible.

## The three moments to record

| Moment | What is recorded | What it is for |
| --- | --- | --- |
| The visit | Who attended, when, what they did | Justifying the contract and invoicing without argument |
| What was found | Condition, readings, photos | Recommending and, if something happens, proving you warned |
| What was recommended | With date and the client's response | It is what protects you when the client did nothing |

> [!IMPORTANT]
> The third saves service companies most often. If you recommended replacing a part and the client chose to wait, that dated recommendation is the difference between their breakdown and your liability.

## How to do it from the road

1. **Job sheet signed on the spot, on a phone** — With the client present. Paper signed and carried in the van gets lost or arrives illegible.
2. **Before and after photos** — Linked to the equipment and the visit, not loose in a gallery.
3. **Recommendations written there and then** — Even one line. A verbal conversation leaves nothing.
4. **And materials used, noted** — It prevents month-end invoice arguments.

> [!WARNING]
> The costliest mistake is the job sheet filled in that evening or the next day "from memory". Readings are lost, recommendations forgotten, and if there is a claim the sheet's date does not match the visit's.

## What the client asks for

**En corto**

- How many visits were made and when.
- What was done at each.
- What is outstanding by their own decision.
- And the history per item of equipment, not per date.

The last is what they value most and what fewest companies can provide: when a client asks about one machine, they want its full story, not the month's visit list.

> [!NOTE]
> It applies equally to facilities maintenance, IT services, grounds care, technical cleaning and community services: the pattern is visit, finding and recommendation, with the equipment or site as the thread.

**What if the client will not sign the sheet?**

Record it anyway, noting the circumstance; better than nothing.

**Does it work without signal on site?**

Fill it in and sync on leaving; what matters is not leaving it for the office.

**Can the client be given access to their history?**

Yes, and it drastically cuts "when were you last here?" calls.

## Ejemplos

**A maintenance company fills in job sheets at night and argues over invoices monthly.**

- Signs the sheet on a phone with the client present
- Notes recommendations and materials on the spot

→ Invoices stop being disputed and a dated recommendation heads off a breakdown claim.

**A technician finishes a job at a client's site and the sheet reaches the office four days later.**

- Captures the sheet at the job itself
- Has the client sign it there and then
- Lets it reach the file on completion

→ The invoice goes out the same day and the client does not dispute what was done.

**The client asks what was done last month.**

- Checks that installation's history

→ You answer without phoning the technician.

**A technician is stopped at the gate over their documentation.**

- Checks per person before assigning the job

→ The job does not go out with a gap.

**Five clients ask for the same documents in five portals.**

- Keeps a single current original

→ All five are answered without redoing the work.

**Equipment goes on site and its documentation sits elsewhere.**

- Stores it with the equipment

→ What travels is found where it is.

**Photos of the work stay on the technician's phone.**

- Uploads them to the file at the moment

→ The evidence outlives the handset.

**A client complains about a job from a year ago.**

- Checks the file with its history

→ You answer from the record.
