Another strong month for the industry side of things. My current position:

And here's the graph:
My current net worth is 12.75Bn ISK That's an increase of 4.35Bn ISK/day or 145mil/day.
That's another record. Nearly a billion more profit this month than last month. That's really good, considering I haven't added any characters, I'm just utilising the ones I have better. I had revenues of 39Bn ISK, an extra 10.2Bn ISK more than last month, which means my profit margin has been 11.1%, very similar to last month at 11.8%. If I can keep this margin and expand my revenues then I'll be very pleased.
The main thing I've tried to change this month is to start looking for processes that can scale. Mostly the form that has taken has been to look for things I build regularly and try to get the input materials from buy orders rather than sell orders to increase the profits per run. The issues with this are that you have to have isk to tie up for a few days while those orders fill, and also you are exposed toa changing market.
An example of this is I started getting input materials for Mobile Depots from buy orders, which improved my margins per depot but then the price of Zydrine spiked and now depots are unprofitable, at least if you buy from sell orders.
Buying from sell orders to sell to sell orders is the most common way to assess an items profitability because that demonstrates the value you are adding purely from the manufacturing process. Any extra profit you can get from buying input materials cheaply or selling in an obscure market or whatever are bonuses. If you have to do those things to make a profit but the item itself is unprofitable you'd be better off finding something else that is inherently profitable to build instead.
As a result I've completely stopped building depots, and taken more of a look at the rigs I build regularly. I build a lot of Trimark Armor Pump IIs (in null) and medium/large Capacitor Control Circuits in both high and null. This is good to identify because it means I can spend a few hundred mill getting materials for those rigs, and some materials are used for both those types, and know that I can use them profitably in the short to medium term.
This feels a step or two away from batching, which is where you have defined batches of products you make and you know in advance when you will start and fulfil those batches, and you might have a schedule for what you make. I believe most large scale industrialists like SirSmashALot operate in this fashion. I don't think I quite have the capital to operate in this way yet, but it's something I want to work towards over the next few months.
Target for this month is to up my profits to 5Bn for the month, and try and utilise 20 reaction slots near 100% of the time. This will involve balancing the input reactions with the composites but should be achievable on a small scale.
