Does job software work without a signal?
· Robert McLaggan
"Works offline" gets used loosely by software that mostly means it doesn't crash when it should. On grafter.ly: install it on your phone and the jobs, customers and dashboard you've opened in the last day or so stay visible with no signal — no blank screen, no browser error. Writing a new quote, sending an invoice, or taking a card payment still needs a connection, because none of that can happen without one. Photos you take on site queue on the phone and upload themselves once you're back in range; a half-written quote doesn't, so finish that when the signal's back.
A lot of job software claims to "work offline." Try it in a basement with no bars and it usually turns out to mean "doesn't crash when the signal drops" — not "you can run your day." That gap matters when you're standing in a new-build with one bar and a customer waiting on a quote.
So here's the plain version of what grafter.ly actually does, and doesn't, with no signal.
What stays visible
Install grafter.ly on your phone — it runs as an app, not just a browser tab — and the pages you've opened in the last day or so stay available even when signal drops: your job list, a customer's details, the dashboard. You're not staring at a spinner or a blank screen. You lose signal walking into a basement with a job's address and notes already open, and it's still there when you look.
That covers most of what you need mid-job — but only for pages you've visited recently. It keeps the last few dozen, for about a day. A job you've never opened, or one you last looked at a week ago, won't appear with no connection — there's nothing on your phone to show you.
What needs a connection, and why
Writing a new quote, sending an invoice, marking a job complete, taking a card payment — all of that needs to reach the server, because the record has to exist somewhere both you and the customer can trust it. There's no way to fake that offline. Try one of those with no signal and you'll get a plain screen telling you you're offline, with a way back to what you can still see — not a confusing error. What it won't do is hold a half-written quote for you while you walk back to the van. Finish that one when you're in range.
Photos are the exception, deliberately. Photograph a consumer unit in a basement with no bars and the picture waits on the phone, then uploads itself the next time the app is open with a signal. It's the one thing on a site that genuinely can't wait, so it's the one thing that doesn't have to.
Everything else picks up as normal the moment signal comes back. No syncing to babysit, no "did that actually send" anxiety — you just carry on.
Why we're not calling this "offline mode"
Plenty of software in this category leans hard on "offline" in the marketing and quietly means "read-only, if you're lucky." Here, the pages you need most on a bad site — what the job is, who the customer is, what's next — stay with you for the day, and the photos you take wait for signal. The bits that can't work without a connection, don't, and we'd rather name them than let you find out in a basement. That's not a failure of the product; it's what "runs on your phone, syncs everywhere" actually costs, and it's a fair trade for never wondering which version of a job is the real one.
Where this fits
Mobile is the floor here, not an afterthought — the whole product is built to run from your phone on a job, not from a desk at the end of the day. Try it free for 30 days — no card to start.
If losing a customer's details on a bad-signal job is the actual worry, how to keep every job out of your head covers the booking side of the same problem.
Common questions
- Does grafter.ly work without a signal?
- Partly. Pages you've opened in the last day or so — your jobs, your customers, the dashboard — stay visible with no signal. Anything that needs to reach the server — a new quote, an invoice, a card payment — needs a connection; there's no way round that. Photos are the one exception: they wait on the phone and upload themselves later.
- What can I still see on site if I lose signal?
- The pages you've opened recently — the job list, a customer's details, the dashboard. Install grafter.ly on your phone (it works as an app, not just a website) and those keep loading from what's already on your phone instead of failing. It holds the last day or so of them, so a job you looked at last week may need signal again.
- What happens if I try to do something that needs a connection with no signal?
- You get a plain "you're offline" screen instead of a blank page or a browser error, with a way back to what you can still see. Photos you've taken wait on the phone and upload themselves when signal returns. Anything else — a half-written quote, an invoice you were about to send — isn't held for you, so finish it once you're back in range.
