Working without signal: keeping job paperwork going in basements and plant rooms
What a trades team needs from their phone when there is no signal on site, and how to make sure nothing done offline gets lost or recorded twice.
By The Osmuch team · · 5 min read
In short
- Assume there will be no signal somewhere on most jobs: basements, plant rooms, rural sites.
- Have the day's jobs, customers and price list on the phone before you leave.
- Anything recorded offline should be kept on the phone and sent when signal returns.
- You should always be able to see what has not gone through yet.
- A change should arrive once, however many times the phone retries.
Trades work happens in exactly the places phones struggle: under floors, in plant rooms, in concrete basements and at the end of country lanes. An app that needs a connection for every tap pushes the paperwork back to the van, or to the evening, where it gets forgotten or written up from memory.
Take the day with you
Before you leave somewhere with a good connection, the phone should hold what the day needs: the jobs you are booked on, their addresses and line items, the customers you are seeing and your price list. With those on the phone, you can look up a part, check what was quoted and see what is next without a signal.
Record now, send later
The things you do on site are small: mark a job finished, log your hours, record a part used, take a sale, fill in a risk assessment. Each of these should be saved on the phone the moment you do it and sent to the office when the signal comes back, without you having to remember. If the phone loses signal halfway through sending, it should try again rather than give up.
Know what has not gone through
The worry with working offline is not knowing whether something made it. A good system shows you what is still waiting to be sent, and tells you plainly if something could not be accepted, so you can put it right rather than finding out from the office a week later.
Nothing recorded twice
Retrying is only safe if a change cannot be applied twice. A sale that is sent, half-received and sent again should arrive as one sale, not two, and a stock adjustment of minus one should take one off, not two. This is the kind of detail you only notice when it goes wrong, and it is worth asking any software supplier about.
Habits that help
- Open the app on Wi-Fi each morning so the day's jobs are on the phone.
- Record things as you do them rather than at the end of the day.
- Before heading home, check that nothing is still waiting to be sent.
- Keep the app up to date, so it and the office are working from the same version.
Questions
Can I use a job management app without signal?
Some apps can. Look for one that keeps the day's jobs and price list on your phone, saves what you do offline and sends it automatically when you are back in range.
What happens if my phone loses signal while sending?
A well-built app keeps the change on the phone and tries again later, and makes sure the change only arrives once, however many attempts it takes.
Doing this in Osmuch
The Osmuch app can download an offline kit: the next seven days of scheduled projects in full, your product catalogue and your customer list. With no signal you can update a project's status, adjust stock, take a sale, log hours, fill in a form, add an expense or a to-do, and each change is kept on the phone and sent when you are back in range. Every change carries a key so it is only ever applied once. The Offline page shows what is on the phone, how old it is, and anything still waiting to go through.
