Try buy orders to get the moon materials more cheaply, but you should make profit even with having to buy materials from scratch. Use buy orders for the raw ore too and refine it down (assuming you have refining skills) to cut costs

As with anything in EveO, skills matter. With invention, you need to be sure you have at least L4 in all of the related skills necessary for invention. When possible, use a high-meta base item to increase your chance of success. And don't use decryptors on anything other than ships. It's a waste. BPCs should be max run for modules, single runs for ships.

With production, you need to minimize your waste at all costs. This means (for example) Refinery Efficiency 5 for reproc (in my case) L4 mission loot into minerals use in the build process. Also means Production Efficiency to L5. I have a zero-waste also that I use to reproc all of my L4 mission junk to minimize mineral loss there.

If you're not at Prod Eff 5, you're losing money. If you're not at at least L4 on all invention required skills, you're losing money. I buy from sell orders in all four empires, wherever I get the lowest price, and I build all my own components (like Thermo Triggers, for example). Gotta reduce costs wherever possible.

All of this is documented in detail. If you are interested in proceeding, you need to take the time to learn how to do it right, what to build, and where to sell them. Selling at Jita (for example) if you haven't absolutely maximized your production chain is just a waste: don't even continue. I NEVER sell at Jita; been in the Industry game for years, and survived quite nicely in all this time. PI was god for a while, but I've since stopped because of all the POCO changes: just not worth the hassle in high. I still have some select items being produced at low-cost low sec system, but that's only for a couple items with very nice markups on them.

The key to finding profitable items to invent is their movement rate. As a rule of thumb, low volume goods are harder to invent profitably. This category includes ships that don't die very often and modules that see limited use.

Jita is my preferred source of moon mats.



Not worth it in many cases, the decryptor is expensive and for modules the mats that use moon goo are extra materials, not affected by waste, so not reduced by decryptors



I think my record is 20. It happens



Or there's this thing called the market which has large quantities of minerals. I can use in a day more minerals than I could mine in a week

i buy all my moon mats etc from market and make most of my isk from manufacturing.
I also run null combat sigs for pin money.
It isn't eve it is you.
run the numbers. buy the mats. build the stuff. sell the stuff.
as with all the posts of this nature you missed step one and are now confused as to why your project failed.

No. Decryptors are one-time use and alter the attributes of the resulting BPC (amount of runs, ME & PE levels) und the success chance of invention.
They can be acquired via Exploration.
See also here : Invention Wiki., though the names of the decryptors seem to have changed.

I wonder why this rtarded attitude still persists over 10 years that you should mine your minerals by yourself.
It completely doesnt matter how you get to your minerals, mined or purchased in jita, their value will be still the same.

Same for moon mins - whether you buy them in jita or you mine them yourself, they are just a cost position to be
accounted at market (Jita) price for whatever you do with it.

In case you really mine yourself, its ADDITIONAL GAIN from mining and shouldnt be taken into calculation
of manufactoring profits.

I disagree with this. There are some items which at ME -6 have the same waste as at 0 ME so a 'Cryptic Augmentation' for example will lead to a 19 run, 'same waste' BPC as no decryptor and really enhance profits. These t2 items tend to be built using 1-4 of each component.

if you have a so called

(and the only good source is an idiot who sells to you under market price)

you are much better off just producing the already most profitable item instead of something that is only profitable when calculated with your special price in mind.

the above is true for anyone producing for an anonymous mass market without any special interests in mind, that's probably 99% of all T1 and T2 manufacturing.
