External workforce management: how do you monitor contractor workers and control costs?

Many companies rely on contractors and external workers to carry out work and projects that need large numbers of people, especially in sectors built on field sites, construction projects, operations and maintenance, and services. But as the number of workers outside the company's direct structure grows, a different problem appears: how can management know who turned up, where they are working, how many hours they actually worked, and what the contractor is really owed?

This is where external workforce management matters, as a process that goes beyond recording workers' names or keeping contractor details. The company needs a clear view of attendance and sites, a link between workers and projects, a review of what is owed, a measure of contractor performance, and a way to tell whether the people it is paying for deliver the operational value it needs.

In companies that run more than one project or site, contractor management gets more complex, because the data may be spread across site supervisors, Excel files, email, attendance sheets and contractors' monthly invoices. The more the company relies on manual procedures, the harder it is to get a single, accurate picture of the external workforce.

Dawmt offers a "Subcontractor" module for managing contractors and the external workforce. It covers contractor profiles, site attendance, and daily, weekly or monthly payouts.

The "Subcontractor" module is an optional add-on to a Dawmt plan, not part of any plan itself. You can see the plans and add-ons on Dawmt's HR system plans.

What is external workforce management?

External workforce management is organising and monitoring workers supplied through outside companies or contractors, rather than employees who work directly for the company.

The process usually covers a set of data and procedures, such as contractor details, worker details, the sites they work at, clock-in and clock-out times, working hours, what is owed, productivity, and an assessment of commitment and delivery.

External workforce management is not limited to counting the people on site. It extends to making sure that the workers the company is charged for are the workers who actually turned up and worked at the agreed sites and times.

This point matters especially for companies that deal with many contractors, because the gap between what is recorded on paper and what actually happens on site can turn into a large operating cost that is hard to spot without a central system.

Why has external workforce management become a challenge for companies?

When a company has one contractor and a few workers at one site, following up may look simple.

But what happens when you have several contractors, several sites, hundreds of workers, different shifts and projects running at the same time?

This is where the challenges of contractor management start to appear.

The site supervisor may be responsible for recording attendance, while human resources (HR) keeps the contractor details, finance keeps the invoices, the project manager follows progress, and what is owed is reviewed in separate files.

This way, each department sees part of the picture, while management needs to see all of it.

That is why effective external workforce management needs data brought together and processes linked, instead of handling each part separately.

Through Dawmt's HR system features, companies can see what the platform does to automate HR processes and bring data and analytics into one system.

The main challenges of managing contractors and an external workforce

1. Not knowing how many workers are actually on site

One of the biggest challenges in external workforce management is having a list of workers' names but no accurate, up-to-date view of who actually turned up.

The number of workers on site can change from one day to the next, some workers may move between sites, and new workers may join while others leave.

If the data depends on handwritten sheets, reviewing it gets harder.

When attendance data is linked to the system, management gets a clearer view of the workers who are actually there.

2. Difficulty confirming where a worker is

In multi-site projects, knowing that a worker turned up is not enough.

You also need to know where they turned up.

If the company runs one project in Riyadh, another in Jeddah and further operating sites in other cities, recording attendance without linking it to the site may not be enough to check how the workforce is distributed.

This is where site data becomes an important part of managing contractor workers.

The "Subcontractor" module in Dawmt records contractors' attendance at work sites.

3. Attendance sheets that do not match invoices

This is one of the points that most needs careful review.

The contractor may submit a monthly sheet with a certain number of workers and a set number of working hours, while the company has different data from the site.

Without a clear way to reconcile the two, reviewing the invoice can take a long time.

Here, external workforce management can help by linking attendance data and what is owed, instead of reviewing each item separately.

4. Difficulty assessing the contractor

It is not enough for the company to know that the contractor supplied a certain number of workers.

The more important question is: did the contractor perform to the required standard?

• Do the workers turn up reliably?
• Is the agreed number supplied?
• Are absence rates high?
• Is the work done on time?
• Do the same problems keep coming back?

This data helps turn contractor management from an administrative task into a tool for making decisions.

Why is Excel not enough for external workforce management?

Excel files can be useful when the volume of data is small, but they get more complicated as the number of contractors, sites and workers grows.

Imagine you have ten contractors, each with dozens or hundreds of workers, and every site sends a daily or weekly sheet.

You will need to update the data, review attendance, compare names, check sites, and then match hours against what is owed.

With every manual step, the chance of an error or out-of-date data goes up.

The problem is not Excel itself: it is that external workforce management needs data that changes all the time, linked processes, and users from different departments.

That is why a dedicated system is a better fit once the external workforce becomes a core part of the operating model.

Managing attendance at work sites

Attendance is one of the most important parts of external workforce management.

Attendance is not just proof that the worker was there: it feeds into working hours, what is owed, contractor assessment and workforce planning.

In companies with field sites, it can be hard to apply one attendance method across all sites.

Some sites may have fingerprint-based biometric terminals, some need mobile apps, and some may be temporary or far from the main branches.

This is where a system that can handle more than one way of recording attendance matters.

Dawmt's attendance module offers features such as geofencing, geo-tagging, selfie verification and integration with external biometric terminals, as well as calculating actual working hours.

How does site management help you monitor an external workforce?

Having more than one site means external workforce management needs the data split by site.

Management can ask:

• How many workers are there at each site?
• How many workers turned up today?
• What is the absence rate?
• How many hours were actually worked?
• Which contractor has the highest rate of commitment?
• Which site is short of workers?
• Is there a gap between the planned and the actual headcount?

These questions matter even more in companies built on projects and field sites.

With organised data, management can spot a shortage of workers before it turns into a problem for the project.

Linking external workforce management to projects

In many companies, the external workforce does not work without a defined assignment: it is assigned to a specific project, contract or site.

So it helps the company to know the cost of workers and the working hours at project level.

For example, if you have two similar projects but the labour cost in one is much higher, management may need to know why.

• Are there more workers?
• Are overtime hours higher?
• Are workers poorly distributed?
• Is productivity lower?

This is where external workforce management becomes part of project management, not just HR.

In Dawmt, the "Project Management" add-on lets you assign employees to tasks and log working hours and their cost to each project, while the "Costing" module shows cost centres and each employee's monthly cost.

You can also use the article Smart workload management: how to allocate tasks fairly and sustain team performance when analysing the relationship between the volume of work and the resources available to projects.

Managing the cost of an external workforce

Cost is one of the main reasons external workforce management is a strategic subject and not just an administrative task.

When a company deals with a contractor, it needs to know the real cost of the service it gets.

There may be an agreed daily, weekly or monthly rate, and rates may vary by type of worker, project or number of working hours.

If the attendance data is not accurate, calculating what is owed gets harder.

That is why the "Subcontractor" module in Dawmt keeps contractors' site attendance and their daily, weekly or monthly payouts in one place, so payouts can be checked against the attendance recorded.

How do you prevent errors in what contractors are owed?

You can build a clear review cycle that starts with the worker's data and ends with payment.

Step 1: Record the contractor's details

The company should have a clear database for each contractor, with the contractor's details and the workers who belong to them.

Step 2: Register the workers

Each worker is linked to their contractor and to the site or project where they work.

Step 3: Record attendance

The worker's clock-in and clock-out are recorded and linked to the site.

Step 4: Calculate working hours

Actual working hours are calculated from the recorded data.

Step 5: Review what is owed

What is owed is calculated according to the rules agreed with the contractor.

Step 6: Review performance

The process does not stop at payment: the data is used to assess the contractor.

This cycle makes managing contractor workers more accurate and reduces reliance on separate files.

Assessing contractor performance using data

A common mistake is to assess a contractor on personal impressions or on the problems that came up in the last month.

It is more useful to base the assessment on data built up over time.

You can follow, for example:

• The attendance rate.
• Whether the agreed number of workers is supplied.
• Actual working hours.
• Absence rates.
• Whether workers stay on their assigned site.
• Productivity.
• How quickly replacement workers are supplied.
• The cost of the workers.
• Whether payments are regular.
• The quality of delivery.

Contractor management then becomes a continuous process, not just a review of contracts and invoices.

The attendance and payout data that the "Subcontractor" module collects is the basis for this assessment, and renewal decisions can then be based on actual data.

When does a company need an external workforce management system?

The size of the company is not the only deciding factor.

A mid-sized company may rely on a large number of contractors and sites, and so need a dedicated system more than a larger company with only in-house employees.

Several indicators show that it is time to improve the way you manage your external workforce:

When the number of contractors grows

The more contractors there are, the harder it is to manage the data by hand.

When sites multiply

Multiple sites need attendance data linked to each site.

When invoices become hard to review

If reviewing what contractors are owed takes a long time every month, the data processing may need to be automated.

When attendance discrepancies appear

A recurring gap between the contractor's sheets and the company's data is an important signal.

When contractors are hard to assess

If management cannot tell from the numbers which contractor performs best, it may need more accurate reports.

External workforce management in multi-site companies

Companies that run many sites face a bigger challenge.

The project manager may be at a different site from HR, and the contractor may be in another city, while invoices are processed by finance.

Each party needs a different part of the data.

That is why external workforce management needs a central platform that lets each party reach the information it needs, according to its permissions.

This cuts the time spent sending files and asking sites for data.

It also helps standardise how information is recorded and reviewed.

The role of the kiosk at field sites

Some sites do not have much technical infrastructure, so companies need a practical way to record workers' attendance.

This is where a kiosk can be a useful option.

In the Dawmt Kiosk app, the supervisor's phone becomes an attendance station: it records workers' attendance by scanning each worker's QR ID card, and it is designed for workers without smartphones, such as those on construction sites and in factories.

This makes the kiosk an important feature in external workforce management, especially at sites that need quick attendance recording without relying on traditional fingerprint-based biometric terminals.

External workforce management and self-service

Not every external worker needs access to every function in the system, but suitable self-service can reduce the administrative load in some procedures.

In the Dawmt app, employees clock in, see their attendance history and swap shifts, while managers find their team's requests in one inbox in the app.

You can look at the Dawmt employee self-service app to see the functions available and how self-service helps reduce manual procedures.

How do reports help improve contractor management?

Reports are the stage where data turns into decisions.

A large database of external workers is not enough if management cannot use it.

So contractor management needs clear reports such as:

• Worker attendance by site.
• Working hours.
• Absence.
• Number of workers by contractor.
• What is owed.
• Labour cost.
• Contractor performance.
• Contractor comparison.
• Productivity.
• Workers by project.

With these reports, management can move from manual review to analysis.

Dawmt offers a "Smart Reports" module that turns HR data into dashboards and reports on headcount, turnover and documents nearing expiry.

What is the difference between following up a contractor and managing contractors?

There is an important difference.

Following up a contractor may mean making sure the workers turned up and the project is progressing as planned.

Contractor management is broader than that.

It covers the data, the workers, attendance, sites, what is owed, costs, performance, reports, and decisions about renewing or changing the contract.

This difference matters because companies that only follow attendance may not have the data they need to know the real cost or the performance of each contractor.

External workforce management and reducing operational risk

The larger the external workforce, the greater the need for clear responsibilities and clear data.

If the company does not know who is working on site, when they turned up, which contractor they belong to or how much they are owed, it may face operational and financial problems that are hard to solve later.

Organised data, on the other hand, helps document processes and makes them easy to go back to when needed.

This is one of the things that makes external workforce management part of the company's operational governance, not just a tool for recording attendance.

Is external workforce management suitable for small companies?

It may be, if the company relies heavily on contractors or external workers, even if it has few in-house employees.

What matters most is not the number of in-house employees but how complex the external workforce is.

If the company deals with several contractors, sites or contracts, a system that helps organise the data can save a lot of time for HR, finance and site managers.

How does a company start organising its external workforce?

You can start with five clear steps:

1. List all current contractors.
2. Standardise the data of the workers who belong to each contractor.
3. Set out the sites and projects where each worker works.
4. Adopt a clear way of recording attendance and working hours.
5. Link attendance data to what is owed, to reports and to performance assessment.

After that, the company can improve the process step by step based on the data that comes in.

Why is external workforce management an important opportunity for companies in Saudi Arabia?

Many sectors in the Saudi market are built on projects, sites and a varied workforce, so workforce management does not stop at the employees inside the company's direct structure.

An external workforce means an extra party in the work cycle, and the more parties there are, the greater the need to bring the data together.

That is why external workforce management helps companies get a more accurate view of the people who actually work on their projects and sites.

It also gives management a better basis for reviewing cost, performance and planning.

How Dawmt brings these processes into one system

What matters in Dawmt is that external workforce management is not cut off from the rest of HR.

The platform has 18 modules, including attendance, leave, payroll, shifts, costing, business intelligence, kiosk, "Project Management" and "Subcontractor", the last two of which are available as add-ons to a plan.

This connection matters because external workforce data can be linked to attendance, sites, projects and costs.

Instead of keeping contractor details in one file, attendance in another and invoices in a third, management can build a more connected data cycle.

If your company is looking for one complete solution instead of relying on separate systems, you can see what the platform does on Dawmt's HR system features.

External workforce management is not just recording workers' names or following their attendance on site.

It is an integrated process that starts with building a database of contractors and workers, then follows attendance and sites, calculates working hours, reviews what is owed, analyses cost and measures performance, and ends with more accurate decisions about contractors and projects.

The more contractors and sites there are, the harder it is to rely on spreadsheets and manual files, and the greater the need for central data.

That is why modern contractor management depends on being able to link attendance to the site, workers to the project and working hours to what is owed, and then turn all this data into reports that help management decide.

Dawmt offers the "Subcontractor" module for managing contractors and the external workforce. It covers contractor profiles, site attendance, and daily, weekly or monthly payouts.

Having attendance management, reports, costing, projects and the kiosk in the same platform also lets the company build a more joined-up view of the workforce at its sites.

In the end, the question management should ask is not only:

"How many workers do we have through contractors?"

but:

"Do we know where they work, when they turned up, what they cost us, and how well they perform?"

When a company can answer these questions with accurate data, external workforce management turns from an administrative burden into a real tool for improving operations and controlling cost.
