Estimating

A cost built up line by line.

You can only defend a cost if you can see what it is made of. Blake builds it line by line from material, machining, finishing and one-off costs, at the hourly rates of your own machines.

At a glance

  1. Cost build-up

    Material, machining, finishing and one-off costs, each on its own line.

  2. Quantity breaks

    A price per part at every quantity, with the same build-up.

  3. Your own rates

    An hourly rate per machine; you confirm proposals line by line.

Step 1

Every cost on its own line

An estimate is made of lines: stock material, machining, finishing, setup and programming. Each line shows whether it applies per part or per batch, and machining time is priced at the hourly rate of the machine that makes the part.

A proposal stays marked as a proposal until you confirm it, line by line, so everyone knows which figures have been checked. Anodising and other outsourced finishes get their own line, priced from your own supplier list.

Step 2

Why a part costs more at 10 than at 50

Setup and programming are paid once per batch. At 10 parts each part carries a large share of that, at 50 a small one. Blake works out every quantity with the same build-up, so quantity breaks are no longer a spreadsheet job.

Material, machining and finishing stay the same per part; only the one-off share comes down. Want to see another quantity? Add a break.

Only the one-off share per part changes with the batch.

Step 3

From cost to quote

The quote follows from the same estimate, through operations, setups, the estimate and the pricing step. You set margin and selling price at the pricing step, with the cost right beside them, so the two never blur.

Every quote version is kept and goes out as a PDF, with CSV and JSON export. Whoever has to defend a price has the build-up to hand.

Cost and selling price stay two numbers.

Who it is for

One cost for everyone who has to stand behind it.

  • Cost engineers

    Build the cost from lines at your own rates, each marked per part or per batch.

  • Manufacturing engineers

    See which machine and how many setups the cost is based on, and change the route where the shop floor does it differently.

  • Technical sales

    Defend a price with the build-up behind it, and see at every quantity what the one-off share per part does.

  • Inside sales

    Read in one table what 10, 25 or 50 parts cost each, without mixing up cost and selling price.

Frequently asked questions

Is your question not here? Talk to sales

What is a cost in Blake made of?

Lines: material, machining, finishing, and setup and programming. Every line shows its time, rate and quantity, and whether it applies per part or per batch.

Which operations does Blake estimate?

Milling from 3- to 5-axis, turning, mill-turn, drilling and tapping. Outsourced finishing counts as its own line.

Can I change a proposal in the estimate?

Yes, with a reason. That keeps on record which figures were changed, by whom and why.

Is the cost the same as the selling price?

No. You set margin and selling price separately. The quote follows from the same estimate, with the cost beside it.

How does a quote go out?

As a PDF, with CSV and JSON export. Every version is kept.
