GPS time clock for NYC construction crews
Hours proved by where you stood.
One tap at the job site. Location-verified hours, site records and payroll — including certified payroll for public jobs — without chasing your crew.
The card
Safety cards, read the moment they arrive.
A new man photographs his SST card in the app. SHIFT reads the card type, the expiry and the name on it. If all three are clear and the name matches, it approves the card and leaves it at the top of People for a second look. If anything is unclear, it goes to the office with the fields already filled in.
Can’t read a card? Ask him for a new photo: until it arrives he cannot clock in on your sites. Card photos are read by Claude, by Anthropic, and are not used to train it. Shown on an invented card; no real card appears on this page.

The site
Who made it to the site, and his card with him.
Each tap lands in two places at once: On site now for the office, and the site safety training log for the inspector. Men from a subcontractor you invited show up as SUB, with their cards. The QR sign on the fence opens today’s log without a login. Turn on site alerts and the office also hears when a man walks off mid-shift, and when he comes back. Standing at the gate without tapping in? With location set to “Always”, the app reminds him on working-day mornings, and the office sees him as at the site, not clocked in.
Arrival times are real: 200 East 95, Thursday October 8. Names changed.

Friday
The week adds itself up.
A full day is 1. On a site where overtime counts, every hour past eight adds an eighth; on one where it doesn’t, only the foreman’s number can make a day longer. Two sites in one day share it. Every correction keeps its reason, and the office reviews the week before it goes out.
Paid by the hour or by the day. Night, weekend and union premiums apply only to the minutes that match; a night shift stays with the day it started.

Optional tools · included
Switch on what your crew needs.
Nine tools. All included. All off until you switch them on in Settings, so nobody sees buttons they will not use.
01
Equipment
Tag equipment with QR labels or Bluetooth tags. See who has it and which site it’s on.
02
Site forms
The DOB records: pre-shift meeting, orientation, scaffold log, visitors. Signed on the phone and kept with a tamper-evident record.
03
Daily log
The report the GC asks for: crew, photos, extra work — and the day’s weather for the site, recorded with the log.
04
Schedule
Who goes to which site this week and next. Missed scheduled starts are flagged.
05
Time off
Asked for on the phone, approved in the office, kept off the schedule.
06
Signed timesheets
Each worker confirms the week with a signature. A PDF for the file.
07
Mileage
Work trips logged on the phone, approved, and paid at your rate per mile.
08
Job budgets
Hours against the budget, per job and per trade, before the job runs over.
09
Crew clock-in
The foreman clocks in the crew from his phone, at the site, for workers without one.
Also available A tablet at the gate: clock in by name and PIN, with a selfie. Priced separately, on request.
In development AI cameras on site, for contractors who ask for them: heads through the gate against clock-ins, hard hats and vests, someone on site after hours, machines in and out, what work is going on. No face recognition. On request.
AI assistant · ChatGPT or Claude
Ask your timesheets a question.
Connect your company’s own ChatGPT or Claude, then ask in plain words, in that app. It answers from the same numbers as your office pages: who is on the clock, the week’s hours and pay, projected overtime and budgets, the next working day’s headcount, and what looks wrong before payroll.
- Cannot change timesheets or pay. It answers and suggests; fixes come back as text, for the office to make.
- Limited to your company’s SHIFT records. The owner or an admin signs in to SHIFT and approves the connection, and can disconnect it in Settings. What it looks up goes to your AI provider, under your plan’s terms.
- Day checks only with the owner’s permission. A separate switch in Settings lets it start or end a temporary day check: workers only, by default up to 14 days and 10 people at a time, with a reason every time and an email to the owner.
How to connect: Settings → AI assistant gives the address to add as a custom connector in ChatGPT or Claude; you sign in to SHIFT and approve it. Works on plans that allow custom connectors. SHIFT charges nothing extra.

Who goes into overtime this week?
Projected: two men, both on 455 W 34th St. At this week’s pace Luis Ortega passes 40 hours on Thursday afternoon and Tomasz Nowak on Friday morning. The site’s labor budget is projected to run out on November 20.Projection from this week’s hours · an estimate
Anything I should fix before payroll?
One forgotten clock-out: Andre Silva, Tuesday, closed by the server at the end of the day. A site check recorded his phone outside the site at 4:34 pm. Confirm his real finish time with him or the foreman, then correct it in the weekly report.From clock-ins and site checks · the office makes the change
In the crew’s pocket
One screen, one big button.
No account and no password: a company code from the foreman and his name. English, Spanish, Russian, Polish, Portuguese or Chinese, switched whenever he likes.
His month in four colours
A day worked, overtime the foreman set, a forgotten clock-out, an emergency clock-out. He checks his own days before anyone else does.
The photo at clock-out
One picture of the work when he leaves. If the camera won’t open, he can still clock out, and the office sees why.
Extra work from the site
A foreman sends a change order with the hours and up to five photos, without a phone call.
Where it goes
The office already has the tools. SHIFT feeds them.
Payroll exportsExcel, QuickBooks Desktop and Online, ADP, Gusto, Paychex. Names and codes mapped once, then every week.
Construction accountingSpectrum, Sage 300 CRE, Foundation, Vista, Sage 100 Contractor: job, cost code and craft on every line.
Every MondayA CSV copy of every clock-in and clock-out, worker, site and time correction, emailed to the owner and admins.
Office connectionsMorning and afternoon email, notifications on the owner’s phone, a read-only API, and your own ChatGPT or Claude.
A second copy, kept elsewhereEvery two hours the database is copied, encrypted, to a second cloud run by another company; photos and safety cards follow once a day. A copy is restored and checked every day, and monthly copies are kept for seven years.
What it does not do
Location checks, with clear limits.
The phone’s position is checked against the site when a man clocks in and out. Every other check has a fixed window, shown below, and keeps how far he is from a site rather than where he is.
AMBefore clock-inOn by default; the company can switch it off. Working-day mornings, 5 to 11, until he clocks in: how far he is from the nearest site and the site he worked last, so the app can remind him at the gate. Kept 90 days.
INClock inHis position is checked against the site. The minute is recorded.
ONOn the clockSite checks, only if the company turned them on. The office hears that he left and how far, not a trail of where he went.
OUTClock outOne photo of the work, the minute, and the on-shift site checks stop. A day check keeps to its own window.
Day check. Switched on separately for each worker, for a period the office picks (at most three months), shown on his screen with its end date. On his working days, from half an hour before the site’s hours to half an hour after, clocked in or not, the phone reports about every five minutes how far he is from the site, never where he is. The office hears if he is late, at the site without clocking in, or leaves early. While it is on, he clocks in only with location set to “Always”.

Paying for your subcontractors? Turn on “Pay for your subcontractors” for shared sites. You pay for their workers who clock in only on your sites. The subcontractor uses SHIFT free.
What counts as a worker?
Anyone who clocks in at least once during the month counts once, however many days he works. Workers who don’t clock in aren’t counted. Office staff who never clock in are free.
When am I charged?
Your first 30 days are free, with no credit card required. After that you are charged at the end of each billing month for that month’s count, never less than $20, plus applicable sales tax. Your billing month starts the day your free month ends.
What happens if a payment fails?
Your crew can still clock in, and existing records aren’t lost. Office pages are unavailable until the bill is paid.
Can my general contractor pay?
Yes. A general contractor can pay for subcontractor workers who clock in only on its shared sites. Those workers go on the GC’s bill, and the subcontractor uses SHIFT free.
USD. Charged at the end of each month through Stripe — card, Apple Pay and other methods — based on that month’s worker count. Prices exclude applicable sales tax. An optional gate kiosk, and AI site cameras once they are ready, are priced on request. Terms of service
