Interesting, so they weren't earning their keep, not moving fast enough, or? I'm curious if you don't mind sharing (or send me a PM if you prefer).
No, I don't mind sharing. To be specific, my first trilogy was picked up by Malachite Quills, and by their spin-off imprint Chimera Tales. They are a small publisher that started with fantasy and sci-fi.
They did some good things for me right off the bat: got a me an editor I really like, and from whom I learned a ton, and got me cover art. They got the books posted to Amazon and Barnes & Noble. But that's about where things came to rest, and where I started having some issues.
First of all, they only did ebooks at first. I wanted to be able to sell paperbacks at events, and many of my relatives don't use ereaders, given their ages. When they finally did come out with the paperbacks, the formatting was crummy (I could, and did, do better on my first try) and it was frankly embarrassing. Then, they couldn't figure out their distribution system, and at this point, I'm unable to obtain my own books from them due to this failure! They could only distribute in lots of 50, and had to have the books shipped to them first, then to me - which made no sense and increased the cost.
Second, their publicity efforts were lousy. I never was able to find any publicity they did on my behalf, although they claimed they had taken out "Google Ads". I did all the rest of the publicity myself: set up book signings, took out ads, printed posters and flyers, etc. I began to think, if I'm doing all this myself anyway, why not do it ALL myself? I also never got them to supply me with a large-scale hi-def version of my covers for publicity.
Then, of course, I had no control over the pace of publication, or whether they were going to publish the sequels to the first book at all. I felt like I was twisting their arm. I finally requested, and received, rights to the third book. They gave me verbal permission, and I had to specifically request that they write it down! They retain rights to the first two, but aren't doing any publicity.
Because I don't own the first two books, I can't do giveaways or adjust the prices myself. The only way for me to give one away is to buy it myself, then send it to someone.
Yes, there's the 'prestige' of being with a publisher, and the validation of having your book picked up by someone else. But at this point, I'm interested in trying things for myself. This has a few advantages:
1) Full control of publication dates, formatting, distribution, and publicity
2) Cheaper prices on paperbacks, and I can buy the specific number of copies I want instead of a lot of fifty
3) Not doing any more work than I was, anyway, except the formatting
4) My own choice of cover artists (and I bear the cost) & editors/alpha/beta readers
5) My formatting is frankly better and more professional looking.
6) I can take advantage of the growing number of support groups and opportunities offered to Indies but not to large publishing houses (contests, etc.)
Anyway - there's probably more - but that's my take on it at this point in time. Subject to change.
