I’ll develop a custom spreadsheet for you. I can make a spreadsheet for almost any industrial concern with whatever information you desire including comparisons in prices between market hubs, build vs sell cost, variable ME input, etc.
Here’s a screenshot of an example I made for a friend recently: https://i.imgur.com/1OY1pqu.png
I can customize a spreadsheet for extreme detail and advanced calculations or it could be simple and show some basic industrial math. I can also include additional sheets like ledgers.
It will be delivered via google sheets and I can update it as necessary for changes to the game at your request.
I can create you a sheet using ESI or help you rebuild a sheet that no longs works because it was using XML/CREST.
Send me a mail with details of what you require and we can talk about pricing.
