Hourly Workforce Time Tracking & Scheduling3 min readUpdated September 2026

Tracking Timesheets Across Every Client Site Your Temps Cover

A staffing agency tracks temp timesheets across client sites by capturing one verified record that serves both payroll and client billing. Workers often sit at a different client's site each week, and their approved hours become a payroll obligation to the worker and an invoice to the client, so a wrong timesheet becomes a dispute over marked-up hours.

Buddy Punch and Deputy both support distributed, multi-site hourly tracking, and for a staffing agency specifically, the deciding factor usually comes down to how the agency structures client approval on top of the raw hours.

Why a staffing agency's timesheet has to satisfy two audiences

Every hour a placed worker logs has to work for both the agency's own payroll and the client's invoice approval, and those two processes don't always move at the same pace. A worker might complete a shift on Friday, but if the client's site supervisor doesn't sign off on the hours until the following Tuesday, the agency is stuck choosing between running payroll on unconfirmed hours or delaying pay until approval comes through, neither of which is a great option for the worker waiting to get paid.

Deputy's fit: scheduling placements across multiple sites

Deputy's shift-based structure maps naturally onto how a staffing agency actually works: a temp worker gets assigned to a defined placement, a shift or block of shifts at a specific client site, and that assignment can change from one placement to the next without rebuilding a schedule from scratch. For an agency juggling dozens of active placements across different clients simultaneously, being able to see at a glance who's assigned where, and swap coverage when a worker can't make a shift, is close to the core of the job.

Buddy Punch's fit: a verified record for client-site hours

Because a placed worker's hours directly become a client invoice, having a verified, timestamped punch record matters more here than in almost any other hourly business. Buddy Punch's GPS geofencing can confirm a worker actually clocked in at the client's address, not somewhere else, which becomes valuable evidence if a client ever disputes hours on an invoice. For an agency that's had a client push back on a timesheet before, that verification pays for itself quickly.

Building a client sign-off step into the workflow

Neither tool automatically gets a client supervisor's approval on a worker's hours, but both can be set up with an approval step before hours are finalized. The agencies that avoid billing disputes tend to build this in deliberately: a client-side contact reviews and approves hours within a set window, and the agency's own payroll and invoicing only proceed once that approval is in. Skipping this step to move faster usually costs more time later untangling a disputed invoice than it saves upfront.

A client sign-off step can be built in this way:

  1. Confirm with the vendor whether your plan lets an external reviewer see and approve hours, since client-facing approval is not universal across tiers.
  2. Set an approval step before hours are finalized, so nothing moves to payroll or invoicing while a timesheet is still open.
  3. Give a client-side contact a set window to review and approve each worker's hours.
  4. Proceed with payroll and client invoicing only once that approval is recorded, so disputes surface before the invoice goes out.

Handling a worker who covers shifts at two different clients in one week

It's common for a placed worker to split a week between two client sites, especially in a light industrial or administrative staffing book. Tag hours by client and placement, not just by worker, so each client's invoice reflects only the hours actually worked at their site. A single undifferentiated weekly total forces someone to manually split it after the fact, usually from memory, which is exactly the kind of reconstruction that leads to billing errors and client disputes.

What changes once the agency scales past a handful of clients

A staffing agency running five or ten active client placements can manage scheduling and approvals fairly informally, a shared spreadsheet, a few phone calls. Past that point, the coordination overhead of tracking who's placed where, whose hours need approval from which client contact, and which invoices are still pending, grows faster than headcount does. That's usually the trigger to move from an informal process onto one of these tools rather than trying to scale the spreadsheet further.

Reconciling a disputed invoice without losing the client

Even with a solid process, a client will occasionally push back on a specific worker's billed hours, and how the agency responds matters as much as who's right. Having the verified punch record ready, timestamped, geofenced, with the client site attached, turns a potential argument into a quick documentation check instead of a drawn-out back-and-forth built on competing recollections. Agencies that can resolve a dispute within a day or two by simply pulling the record tend to keep client relationships intact far better than ones that have to promise to look into it and follow up next week.

Build the habit of pulling that documentation proactively whenever a client's site supervisor seems even mildly uncertain about a specific week's hours, rather than waiting for a formal dispute to escalate before checking the record.

Executive Capability Standard

What Good Looks Like

Good workforce management for a staffing agency means every placed worker's hours are recorded accurately at the client site where they were actually worked, client sign-off happens on a predictable timeline, and payroll and invoicing both run off the same approved, undisputed hours.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Review recent client invoice disputes and trace each one back to where the hours were recorded or approved incorrectly.
2. Do Manually:Have placed workers submit paper timesheets that a site supervisor signs before they're passed to the agency for payroll.
3. Delegate:Put a placement coordinator in charge of collecting and confirming hours from each client site every week.
4. Automate:Move to a shift-scheduling tool like Deputy and pair it with verified clock-ins through Buddy Punch so hours are recorded and confirmed as they happen.
5. Buy:Add a client-facing approval workflow so site supervisors sign off on hours directly in the system before payroll and invoicing run.

Frequently Asked Questions

Can either tool send a timesheet directly to a client for approval?

Some plans support sharing hours with an external reviewer for sign-off, but confirm this specifically with the vendor rather than assuming it's included, since client-facing approval workflows aren't universal across every tier of either product.

How do we handle a worker placed at a client site with no reliable cell signal?

Confirm with the vendor whether punches queue locally and sync once a connection returns. For a placement in a warehouse or industrial site with poor coverage, this matters more than almost any other feature, since a lost punch becomes a dispute over hours that were actually worked.

What happens to overtime when a worker is placed at two different clients in the same week?

Overtime is calculated on the worker's total hours across all placements, not per client, when the agency is the employer of record. The agency therefore needs visibility into a worker's combined weekly hours regardless of how many different sites they covered.
