So, create a spreadsheet of said items. A single table of materials, printer, and also services such as design, etc. It's important to devise a strict naming convention as I've mentioned recently elsewhere in other posts on the forum. Maybe name the spreadsheet "Components."
You will also need to create another spreadsheet of "Products" using a strict naming convention and each product will list its components of make-up. (similar to Stacey K's earlier post of the SignTracker image.) A spreadsheet will immediately become unwieldy for this task but create at least one product.
Create yet another spreadsheet and maybe name it "Line Item Breakdown." This is where you'll enter the print dimensions and quantity but it will also show the product make-up along with the calculated values of components which are determined by the print size and qty.
All three tables of this data which are related, get related further to another table of Quotes. And again, this spreadsheet will immediately become unwieldy for the task in practical use. However, the exercise is useful as a reference and to clearly explain the necessity of a true database along with relationships and the design of layouts.
Unfortunately, I don't know of any current web-based solutions that will display such related data as clearly and compact as we've already had for decades now.
More later.
I have 6 tables,
Calculator | Workflow | Stock list | Fees & Data | Print modes | Printers
(in that order)
It works backwards.
In printers, I have everything to do with costs of running each machine. from maintenance, inks, consumables, electricity, etc.
Printmodes - Every printer listed with every print mode. calculates what it costs to use each print mode from the "printers" table
Fees & data is just extra dropdowns used here and there
Stock list - list of all stock. with pricing, area pricing etc.
Product workflow - A table with every product we have. every column has a dropdown to define what's in that workflow. for example "posters". I'll have a column for Printer, Print mode, Stock, Extra supplies, Waste length and a few others.
They're dropdowns from the other tables so you just pick and select.
The calculator - choose the workflow, enter your size and quantity. It'll take that workflow and calculate the cost.
It'll show what it costs to run the printer, how much the total stock will cost and how much profit is left.
I know the calculator is good. I was more looking for something similar that's already software
