Iโm Mark Stay, author of the Witches of Woodville series and The End of Magic trilogy and welcome to the second episode where Iโm sharing what Iโve learned from doing 42 comic cons in 2025โฆ
Letโs talk about costs, sales targets and cashflow. Ooh, exciting! This episode all stems from one very long question fromโฆ
ZOร RICHARDS, author of Tell it to the Bees and Garden of her Heart (not an author of fantasy or science fiction, but she sells at craft markets)
Zoรซ asks: What do you class as a good day/event?
Iโm not after sales figures, rather the formula you use. This is what Iโm using, and Iโd love to know if it aligns with yours.
Zoรซ lists her costs asโฆ
โข cost of stall
โข additional costs (travel, parking, refreshments)
โข depreciation costs (banner, bookmarks, table cloth, display materials)
โข Costs for debit card sales (each sale incurs a small fee)
โข cost of books ordered (like me, she gets author copies from her publisher at 50% RRP)
Then Zoรซ tallies that against her:
โข targeted sales
โข actual sales
โข income from sales
And the final result is:
โข Total income from sales
โข Minus total costs
Zoรซ continues: Is this the right approach? I find myself wondering if Iโm doing well or wasting my time. I donโt have opportunities for comic con events as I write the wrong kind of books so mine are craft markets, which donโt always attract readers.
Thanks Zoรซ and thatโs pretty much the approach that I take: I tot up my costs, then estimate how many books I need to sell to cover those costs and target myself accordingly. You can tell I was a sales rep, canโt you?
I keep a spreadsheet with how much the table costs me and the estimated petrol expenses (I use the RAC calculator).
So I can tell you now that in 2025, I sold 1974 books, with a turnover of just over ยฃ20k, spent nearly ยฃ2.5 on petrol, and nearly ยฃ3k booking the events.
What I donโt track are those depreciative costs: the banners, the tablecloths, the bookmarks (and Iโll talk more about them when I do a tour of my table in the next episode)…
And I donโt track my biggest expense: stock (ยฃ6.4k in 2025),โฆ because itโs the expense that never stops and presents its own issue: cashflow.
Now if youโre just starting out, and only have one or two books to sell, go and fetch the smallest of your violins because this is where I complain about the expense of having to regularly stock up on 9-10 published books. It ainโt cheapโฆ
Like Zoรซ, I get my Witches of Woodville books from my publisher, Simon & Schuster, at a 50% discount. And I get my self-published books from Bookvault and they cost between ยฃ5-6 per copy.
What am I complaining about? That sounds like a good markupโฆ Well, Iโve realised that in order to have the stock arrive in time, I have to place the stock order two weeks ahead of the event.
So if Iโm coming off the back of two smaller, quiet events and then have to order for one of the bigger comic cons, and if Iโm doing this every weekend, then Iโm often out of pocket. Big time.
Yes, thereโs a good chance that Iโll make my money back in a couple of weeks at the bigger event, but it means that I often end up overdrawn and it gets a bit squeaky bum timeโฆ and thatโs why Iโm not doing this for the money. Because, by the time youโve totted up your expenses (Iโm also paying for editors and artists and other expenses through my company, including two salaries) and paid your taxes and your VAT bill every quarter, there sort of isnโt any left.
What I get instead are readers. 1974 books that I personally signed and handed directly to readers. Thatโs a much stronger connection than selling something on Kindle for 99p to someone in Buttmunch, Indianaโฆ Thatโs what I keep telling myself anyway. And no offence to the good people of Buttmunch. Go, Buttmunchers!
But hey, in 2026 the plan is to sell even more books! Iโve got a 5 book series, and now a completed trilogy, and more books on the way. So in the next episode, weโre going to talk about sales, and how to sell, and the tools for selling. Iโll even take you on a tour of my table. Ooh! Exciting, eh?
