Know what your
work costs.

Costline records labour and materials against the cost centres, activities and people that used them — at the rates that applied on the day of the work. Past entries don’t change when rates do.

Rates are versioned.
Logs keep theirs.

These are the two screens that make it work: rate changes are added as dated versions, and every log entry stores the amount that was resolved when it was recorded.

Updating a rate adds a version with an effective date. Earlier versions stay.

This exact amount is permanently stored with the log. Future rate changes will not affect it.

The resolved rate and total are stored on the log itself, permanently.

How it works

Three steps, no ceremony.

01
Set up your operation

Pick your industry, then name your cost centres, people, rate types, activities and materials. Most teams are set up in under 15 minutes.

02
Log the day's work

Record time and materials against the work that used them. Rates and prices resolve automatically, as they stood on the day of the work.

03
Read the reports

Cost per centre, labour against materials, trends over time — built from the amounts stored on each log.

Under the hood
Versioned rates & prices

A rate change is a new version with an effective date, not an edit. Past logs keep the rate that applied on their work date.

Costing at the source

Hours and materials are logged against the cost centre, activity and person that used them — that's where the cost lands.

Your structure, your words

Cost centres, rate types, activities and materials are all defined by you. Works for farms, sites, workshops and project teams.

Reports from stored costs

Reports aggregate the amounts stored on each log — they are never recalculated from today's rates.

Try it on your own operation.

Set up your cost centres and log a day’s work — you’ll know within an afternoon whether it fits.
