"Time Tracking for Construction, by Variation"

The job was priced at $14,000

. It is now $19,000, and the client is asking why. The answer is three variations you priced from memory, two site visits you forgot to bill, and a stack of materials receipts that never made it onto an invoice.

This post is for builders, contractors, and construction small businesses that price fixed-fee jobs, manage variations, and are tired of the gap between what a job costs and what the client sees. If your jobs change mid-job and your quotes are only as good as your memory, this is written for you.

#The variation problem

Construction jobs are not static. The client changes the spec. The site reveals something unexpected. A variation comes in, and you need to price it, and you are pricing it from what the last similar job took, adjusted by gut, because the last job's actual hours are in a spreadsheet you have not opened in six months.

The honest way to price a variation is from what the past work actually took, plus a margin for the unknown. But that requires you to know what the past work actually took, and most tracking systems do not make that easy.

owntime gives you the "what the past work actually took" part. Your history is in the file. You can look up what a past job actually billed, what the hours were per stage, and use that as the basis for the variation estimate. The estimate lives in the estimates view, line by line. When the client accepts, one click converts it to an invoice draft. There is no retyping the scope into a separate document.

#Materials that make the bill

Construction generates materials costs that are easy to lose. Timber. Fixings. A last-minute run to the supplier. These go on your card, and if they are not captured, they are just a loss, or worse, they are a dispute with the client about what was included in the fixed fee.

owntime handles these as expenses with receipts. Photograph the receipt, mark it billable, attach it to the job, and it sits against that client until the next invoice. When you invoice, the materials ride onto the PDF as their own line items, next to the hours, properly labeled. No separate materials schedule. No receipt you forgot to claim.

I will be honest about the capture moment. The expense has to be logged. If you get back from the supplier and do not log the materials that day, the receipt will sit in your wallet until it is gone. The tool does not remind you about expenses. But once they are in, they stay billed.

#Job costing, light

A construction job has hours, a budget, and a burn rate, and the three numbers have to reconcile or the margin disappears. owntime gives you hours against a budget per job, with alerts at 75, 90, and 100 percent. A job lead can see, week by week, whether a job is on track or burning, without running a report.

This is not an ERP. It does not do progress claims, retention tracking, or subcontractor management. It is time and invoicing with a light layer of job costing, and it is the layer most small builders can actually use on a Friday at 4pm, offline, on site.

#The honest limits

owntime does not do live multi-person dashboards. Each person keeps their own file. If your site needs a live view of who is on what job right now, that requires a server, and that is the trade this product avoids.

It also does not do project management, drawing registers, or compliance tracking. If your business runs on a dedicated construction management tool, owntime is a companion for the time-and-invoice layer, not a replacement.

If your jobs change mid-job, if variations are priced from memory, and if materials receipts are disappearing, this workflow will help. The variations get priced from real hours. The materials stay billed. The job costing is light enough to use and honest enough to trust.
