Lead times

Tell buyers 'when' before they have to ask.

The buyer enters what they want and gets a ships-by date in real time, computed against your actual backlog. The schedule comes from a spreadsheet you already keep.

How it works

01

The schedule lives in a sheet

You already track who's working on what and when, even if it's just a column of dates. The calculator reads that sheet and knows your real backlog.

02

Buyer enters what they want

Type, dimensions, quantity, complexity, rush or no rush. Each input shifts the date in real time, so the buyer can see the trade-offs as they configure.

03

Honest date out

Based on the next genuinely available slot, plus base time for the work, plus shipping. Updates whenever the sheet does, so the date the buyer saw on Tuesday is still good on Friday.
