Lead times
Tell buyers 'when' before they have to ask.
The buyer enters their piece, dimensions, and quantity. They get a ships-by date in real time, computed against your workshop's actual backlog. The schedule comes from a sheet you already keep.

The problem
Custom work doesn't have a fixed lead time. Your buyer still wants one.
Lead time is the question every buyer asks first and the question every workshop dreads answering. The honest answer is 'it depends': on your backlog, on the piece's complexity, on the size, on whether someone else booked the slot last Friday. So the answer comes a week later, after a few internal emails. By then the buyer has lost interest, or worse, has booked someone else's piece. We compute the date instead. The buyer enters what they want, the calculator reads your workshop schedule from a sheet you already keep, and outputs a defendable ships-by date in seconds. Honest, current, and never out of sync with what the workshop is actually doing.
Situations this fits
You’ll recognise these.
“A buyer asks 'when can I have it?' before they've even confirmed dimensions.”
They get a date in real time, before the conversation even starts.
“A designer has to commit a delivery date for a hotel handover.”
Plug in quantity and complexity, get a defendable date you can both build the project around.
“You're at capacity for the next 6 weeks but still want to take orders.”
The calculator shows realistic slots, sets expectations honestly, no awkward 'we should have said' emails three weeks later.
How it works
Three steps. No human in the loop until the price.
The schedule lives in a sheet
Your workshop already tracks who's making what and when, even if it's just a column of dates. The calculator reads that sheet and knows your real backlog.
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.
Honest date out
Based on the next genuinely available slot, plus base time for the piece, plus shipping. Updates whenever the sheet does, so the date the buyer saw on Tuesday is still good on Friday.
Fits these industries
Same plumbing. Different field set.
What you get
The first answer is the right answer.
No more 'let me check with the workshop and get back to you'. The buyer leaves the conversation with a date in their hand and the workshop schedule that produced it. Built first for Forma Strata's custom rug timeline, the same logic adapts to any workshop where the schedule lives in a sheet.
