Contractor time tracking in manufacturing plants
Contractor time tracking in manufacturing plants, from the plant owner's side.
Contractor time tracking in a manufacturing plant means checking what an outside contractor invoices against the time its crew spent inside the fence. ZeroBadge lets the plant issue a badge to each outside worker for the length of the job. Power on starts the shift, each report lands in the building or yard you drew, power off ends it, and the weekly record sits beside the invoice.

- Hours by building and yard

What ZeroBadge does for you
How ZeroBadge helps contractors in manufacturing plants
One company badge per worker covers safety alerts, timekeeping, labor analytics and ZeroBadge AI. Here is what each part does in your line of work.
01
Worker safety
A plant-issued badge gives an outside worker an alert button, and a restricted-area alert tells the plant when someone enters a zone you draw.
Learn more02
Workforce management
See how many outside workers are inside the fence right now, which contractor sent them and who has not arrived.
Learn more03
Automated timekeeping
Badge on at the plant starts each contractor worker's recorded day, giving the plant its own record to set beside a contractor's sheet.
Learn more04
Workforce productivity
Compare recorded hours with the invoice, line by line on a time-and-materials contract, so the plant pays for hours supported by records.
Learn more05
Location analytics
GPS outdoors and Wi-Fi inside place a worker at a building or yard, never proving work was done and never replacing your access control.
Learn more06
Field logistics
Plan how many outside crews the plant can host at once by looking at recorded headcount by building and day.
Learn more07
AI advisory and analytics
Ask ZeroBadge AI how many contractor hours were recorded at each building against what an invoice bills, from your own records.

Safety alerts support your safety program. They do not replace supervision or training, ZeroBadge does not monitor alerts or contact 911, and in an emergency workers should call 911.
What a plant sees of outside labor
The invoice says 400 hours. The plant has no record of its own to hold it against.
When a contractor works inside your plant or warehouse, you pay for its hours but you do not keep the time. The contractor's sheet is the single account of how those hours were spent.
A gate log counts doors, not areas
A turnstile or visitor sign-in tells you when a person came in and went out. It does not say which building they were in, so a day at the boiler house and a day in the warehouse look the same.
Time-and-materials makes hours the price
On a time-and-materials contract the labor line is what you pay. A few unexplained hours on each of several invoices is real money, and the person approving the invoice has little to check it against.
Several contractors in the same week
A shutdown can bring mechanical, electrical, insulation and scaffolding contractors into the plant at once. Each has its own sheet format, and your contract administrator reconciles them all by hand.
Standing contractors drift
A maintenance contractor on site for months stops being questioned. Its crew size and hours creep, and no one notices because no week looks different from the last.
Questions go back and forth in email
When an invoice looks high, the exchange runs on memories: the foreman's, the plant supervisor's, a gate guard's. A shared set of times would shorten it.
Hours by area
See each contractor's hours by building and yard, week over week.
Draw the buildings, yards and outbuildings that matter to your contracts as locations. Every recorded hour lands in one of them, and hours away from every drawn location show on their own line.
The example company in this view is a construction contractor with several jobsites. A plant's contract administrator would read the same view as hours by area for each outside crew, and would compare it with the work orders issued for each area.

What changed
Riverside Medical Pavilion recorded 375.0 hours, up 129.9 hours (+53%) from the week of Sep 28.
3 workers (Ben C., Mateo G., Rosa D.) recorded time at Riverside from Tue Oct 6 after working at Harbor Yard. Their time accounts for 108.8 of the added hours.
Phone app or kiosk?
How is this different from a phone app or a kiosk at the gate?
Gate hardware records one doorway, and a phone app belongs to someone else's employee. A badge the plant issues records the person across the property, on a device the plant controls.
A kiosk or turnstile at the gate
Records an arrival and a departure at one point. It cannot place a person in a building, and a worker who leaves for a supply run can pass it twice without any record of what happened in between.
A phone app
A plant cannot require a contractor's employee to install software on a personal phone, and many plants keep phones off the floor. The badge needs no phone, no app and no login.
The contractor's own timekeeping
Fine to ask for, and a useful cross-check, but it is the contractor's record. A contractor can also run ZeroBadge on its own crew and share the weekly export; the industrial contractors page covers that side.
The honest tradeoff
Someone at the plant has to hand out badges at check-in, keep them charged and collect them at the end of the job. It is a small recurring task that a gate desk or contractor coordinator takes on.
Setting it up as the plant
What maintenance, purchasing and contract administration will ask.
Who issues the badges
The plant does, at contractor check-in. Each badge is assigned to one named person, and the office can reassign it when the crew changes or mark it lost if it does not come back.
Grouping by contractor
A badge is assigned to a person, not a company. The weekly export lists hours by worker, day and location in CSV, Excel or PDF, so it sorts by contractor in a spreadsheet once you keep your own list of who belongs to whom.
How fine the areas can be
Separate buildings, yards and outbuildings split cleanly. Two rooms inside one building usually do not, so draw the areas your work orders and invoices actually distinguish.
Not access control
The badge opens no doors and does not replace your gate badge or visitor sign-in. Check your own rules for electronic devices in classified areas before issuing one there.
Contract and notice
Put the badge requirement in the contractor agreement and tell each worker what it records: location during their paid shift, nothing when it is powered off. Rules on monitoring differ by state and by agreement. This is general information, not legal advice.
Who sees it
Only users in your own account, set by role. The contractor sees nothing unless you send it an export.
When it is not worth it
On a fixed-price contract, hours do not set what you pay, so a badge record adds little.
The value is greatest where hours are the invoice: time-and-materials work, shutdowns and long-running contractors billed by the hour.
