Tracking Equipment and Products Alongside Time: A Practical Guide

Ask most businesses what a job cost them and they'll give you a labor number — hours worked times a rate. It's the easiest number to get, and it's usually wrong, because it leaves out everything that isn't a person's time: the excavator running for six hours, the fuel and consumables used up on site, the van that put 80km on the odometer. None of that shows up if time tracking only ever asks "who worked, and for how long."

1. Equipment has its own cost, separate from who's operating it

A piece of equipment costs money to run whether or not you think about it: fuel, maintenance, depreciation, insurance. The two things worth capturing separately are:

Time — how many hours the equipment was in use on this job.
Distance — for anything mobile (a vehicle, a truck), how far it travelled, since a per-km cost is often more accurate than a flat hourly rate for transport-heavy work.

Both figures need their own cost and sale price — what it actually costs you per hour or per kilometer, and what (if anything) you bill the customer for it. A job that uses an excavator for a full day can easily have equipment costs that rival the labor cost, and if that's never captured, the job's true cost is understated every single time equipment shows up.

2. Products and materials need tracking by quantity, not guesswork

Consumables and materials — concrete, fittings, cabling, anything used up rather than operated — need a different kind of record: a quantity, a unit (bags, meters, liters, whatever fits), and a cost/sale price per unit. Multiply the two and you get a real dollar figure for materials on that specific job, not an estimate reconstructed from memory or a receipt pile at the end of the month.

The value of doing this at the point of work — logged by whoever's actually using the material, at the time — is that it's accurate. Reconciling material usage after the fact from purchase orders tells you what you bought, not what a specific job actually consumed.

3. Why "who's using what" should be the same record as "who worked when"

The most common failure mode isn't forgetting to track equipment or materials at all — it's tracking them somewhere separate from time. A spreadsheet for hours, a different one for fuel logs, a third for material pulls from the yard. By the time someone tries to work out what a job actually cost, they're reconciling three disconnected sources that don't share a date, a project reference, or a person.

Capturing equipment and product usage as part of the same time entry — the same clock-in, the same project, the same task — means there's one record per piece of work, and the cost of that work (labor + equipment + materials) can be computed directly from it instead of assembled afterward.

4. What this looks like in a report

Once labor, equipment, and product costs are captured as distinct lines rather than blended into one number, a project report can show exactly where a job's cost actually came from:

Cost line	What it captures
Labor	Hours worked, at each person's rate (including any overtime or premium).
Equipment	Hours and/or kilometers of equipment use, at that equipment's rate.
Product	Quantity of materials/consumables used, at their per-unit rate.

That breakdown is what turns "this job cost $4,200" into something actionable — knowing whether that $4,200 was mostly labor, mostly equipment, or mostly materials changes what you'd actually do differently on the next similar job.

5. Common mistakes worth avoiding

Tracking equipment use but not cost. Knowing a machine ran for 6 hours is useless for costing if there's no rate attached to that time.
Estimating materials instead of logging actual quantity. "About half a pallet" isn't a number you can bill or cost accurately.
Keeping equipment/material records separate from time records. This is the one that causes the most reconciliation pain — different systems, different formats, no shared reference back to the specific job or day.
Not distinguishing cost from sale price. What a product or piece of equipment costs you and what (if anything) you bill for it are two different numbers — conflating them hides your actual margin.

6. What to look for in a system that does this properly

At minimum: the ability to attach equipment and/or a product to the same entry as the hours worked, not a separate log; per-unit rates for products and per-hour/per-km rates for equipment, each with their own cost and sale price; and reporting that breaks a job's total cost down by labor, equipment, and product rather than showing one blended figure.

Chronify captures equipment and product usage as part of the same time entry — with its own cost/sales rates for each, rolled up automatically into project cost and profit reporting.
