Labour Hours Sold

Labour hours sold are the labour time units billed or sold to customers for completed work during a stated period. In service businesses, they help compare customer-facing output with available staff time, but they are not the same as clocked hours or cash received.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

A technician might spend three hours on a job billed at two standard labour hours, while another might complete a two-hour billed job in one hour. Sold hours describe the customer charge, not necessarily time on the clock.

Tekmetric reports technician hours and Shopmonkey documents time logs for repair shops, but their report fields can differ, so define the exact measure in the system used. A fictional workshop bills 40 labour hours this week while its staff clock 50 hours at work, including cleaning and training, so the 40 is not an attendance record.

A service quote may use actual time or a fixed labour allowance, and under flat-rate pricing billed hours can exceed or fall below actual task time, so check the contract and invoice method. A fictional mechanic repairs a car in 1.5 hours and invoices 2 standard hours, so the shop records 2 sold hours and 1.5 actual task hours, and both numbers serve different purposes.

Set rules for invoiced, approved but not invoiced, discounted and warranty work, since a rework job may consume time without new customer revenue and counting it as sold hours can distort results. A fictional agency completes 10 project hours but grants a full credit for an error, so it reports productive time and net sold hours separately, because the credited work does not become new customer revenue.

Calculate sold hours from invoice lines or approved billable records consistently, remove duplicates and reversals, and if a job crosses reporting periods, choose a recognition date and disclose it. A fictional repair order closes on Monday after work done Friday, so a Friday work log and Monday invoice report will differ, and the manager does not combine them without reconciliation.

Compare sold hours with paid or available hours only using compatible definitions, since labour utilisation, productivity and efficiency are related but not identical and the numerator and denominator should be defined explicitly. A fictional shop sells 32 hours with 40 paid technician hours, giving a sold-to-paid ratio of 80%, which does not prove workers were idle for the other eight hours.

Non-billable work may be necessary, since training, safety checks, administration and customer communication keep a business operating, and a sold-hours target should not penalise essential tasks. When a fictional service centre spends a morning training staff on a new safety procedure, sold hours fall temporarily, and the manager looks at long-term quality rather than calling the training wasted time.

Revenue per sold hour depends on labour rates and discounts, so two teams can sell the same hours but earn different amounts, as when a fictional shop sells 100 labour hours at an average realised $90 each for $9,000 of labour revenue while another sells 100 at $70, and equal sold hours do not mean equal gross margin. Monitor quality, rework and customer outcomes alongside hours, since pushing more billed time without proper service can create complaints or unfair bills and incentives should support accurate work, and when a fictional manager sees rising sold hours but more warranty returns, the team checks whether work was rushed, because the metric alone does not prove improved performance.

Seasonality and job mix affect comparisons, as diagnostic jobs, installations and routine maintenance may carry different labour allowances, and a fictional shop that assigns complex electrical diagnostics to one technician sees fewer sold hours for that person, so a fair review considers difficulty and rework. Reporting systems may allocate sold hours to technicians, teams or invoices, so clarify who gets credit when several people share a job, avoid counting the same invoice twice and keep parts or material revenue separate if the metric is labour-specific, and treat labour hours sold as a useful operating measure when definitions are stable, paired with actual time, costs, quality and customer revenue for a sound decision.

In practice

Real-world examples.

1

Example

A shop records two billed hours for a repair completed in 1.5 clock hours.

2

Example

An agency separates credited rework from net sold hours.

3

Example

A manager compares sold hours with paid hours using defined periods.

Formula

Calculation

Sold-to-paid ratio (%) = net labour hours sold / paid labour hours x 100, if both use the same period and staffing scope. Labour revenue per sold hour = net labour revenue / net hours sold. Worked example: a shop sells 120 labour hours in a week, of which 8 are credited back for rework, so net sold hours are 120 - 8 = 112. Its technicians are paid for 150 hours. The sold-to-paid ratio is 112 / 150 x 100 = 74.7%. If net labour revenue is $10,080, labour revenue per sold hour is $10,080 / 112 = $90. The 38 hours between sold and paid time (150 - 112) are not automatically lost. Training, safety checks and waiting for parts may explain part of the gap, so the manager reviews them before setting any target.

Case study

Seen in the real world.

In this fictional case, Maple Auto sells 120 labour hours in a week while technicians log 150 paid hours. The simple sold-to-paid ratio is 120 / 150 x 100 = 80%. The owner checks training, rework and rate discounts before treating the 30-hour difference as avoidable loss. The review finds that 12 of the 30 hours were a planned safety training session and 6 were rework on a returned job. The owner records the training as a necessary cost, tracks the rework separately and sets a target only for the remaining time that waiting and scheduling gaps explain.

Watch out

Common mistakes.

  • Equating billed hours with actual task or attendance time.
  • Counting credited rework as new sold hours.
  • Rewarding hours without checking quality and realised revenue.

Questions

People also ask.

Can sold hours exceed actual repair hours?

Yes, especially with standard or flat-rate labour pricing.

Are sold hours the same as paid hours?

No. Paid hours include other work and time.

What else should a manager check?

Rework, job mix, revenue, costs and customer outcomes.
