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.

  • A record the plant owns
  • Hours by building and yard
  • One month or more of battery life*

*Under qualifying operating conditions. Battery life varies with reporting frequency, signal conditions, usage, and configuration.

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 more
  • 02

    Workforce management

    See how many outside workers are inside the fence right now, which contractor sent them and who has not arrived.

    Learn more
  • 03

    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 more
  • 04

    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 more
  • 05

    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 more
  • 06

    Field logistics

    Plan how many outside crews the plant can host at once by looking at recorded headcount by building and day.

    Learn more
  • 07

    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.

    Learn more

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.

Overtime rule shown: after 8 hours in a day or 40 regular hours in a week. Overtime cost adds a 0.5× premium on base wage to the loaded hourly rate. Your own payroll rules apply.

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.

Rollout

Start with one contractor on one time-and-materials job.

  1. 01

    Draw the plant

    Draw each building and yard from its address or the site plan. Name them the way your work orders do.

ZeroBadge AI

Ask about outside contractors

ZeroBadge AI answers in plain English from your plant's own badge records, and every number links to the hours it came from.

  • You ask

    How many hours did Summit Mechanical's crew record inside Building 3 last week?

    Eight Summit Mechanical workers recorded 304 hours inside Building 3, with a daily peak of 8 people. Each worker's hours link to their record.

  • You ask

    Which invoice lines bill more hours than the badge records show?

    Two Summit Mechanical lines bill 40 and 36 hours against 34 and 33 recorded. Each line links to the recorded hours it was compared with.

  • You ask

    How many outside contractors were in the plant at once on Thursday?

    At 10:30 AM on Thursday, 23 outside workers from four contractors were recorded in the plant. The list shows each contractor and area.

Answers come only from your company's own records. Every number links to the records behind it. Read-only; admins control access.

How ZeroBadge AI works

Questions

Questions plant owners ask about contractor time.

Can a plant issue badges to another company's workers?
Yes, if the contractor agrees. The plant is the issuing company, each badge is assigned to one named person, and tracking runs only during their paid shift on the plant's badge. Put it in the contractor agreement and tell the workers what it records.
Does it replace our gate log or visitor sign-in?
No. It opens no doors and does not control access. It adds a record of which of your drawn buildings and yards a badge was placed in during each shift, next to the arrival and departure your gate already captures.
Can it show whether the contractor did the work?
No. It records where a person was and for how long, not what they did. Use it to check hours against an invoice and your work orders, not to judge the quality of the work.
How is this different from the industrial contractors and manufacturing pages?
The industrial contractors page is written for the contractor company that sends crews into plants. The manufacturing page is for a plant's own maintenance crews. This page is for the plant owner reviewing outside contractors' hours.
Is it worth it on a fixed-price contract?
Usually not. When hours do not set the price, a badge record adds little to an invoice review. It earns its place on time-and-materials work, shutdowns and long contracts billed by the hour.
