At the smaller end, Odoo is raising its head. In medium-sized client accounts, the worst competitor is Monitor, but Roiman Lean is also involved there.
Precisely that consulting slump is the problem. It reflects the number of new projects and thus future continuous invoicing. Conversely: when there are no projects, there are no new customers, no invoicing base. However, it often seems that monthly invoicing only starts at the end of the project or during it. I don’t know.
It is true that Lemonsoft has many customers in industry and wholesale. And in that quantity, individual or even tens do not yet quantitatively make a difference. Generally, however, these industrial companies are large enough that one can easily make a big dent in the invoicing base. Compared to, for example, Finvoicer, where customers’ monthly charges are tens per month, whereas in industrial customers, invoicing can be thousands of euros per month.
And once the reputation is gone and customers start leaving, it’s hard to stop. One must remember that Finland is a small country and entrepreneurs talk a lot among themselves. Through that, when someone switches away and gets good experiences from another software, the stern really starts to leak like a lemming herd.
But as @Atte_Riikola noted, let’s wait and see. I hope I’m wrong for the sake of all investors in the company 
I myself sold my Lemonsoft shares after the IPO at levels above 15€/share, as I anticipated what was to come (And of course, at that level, the company’s valuation was completely overblown).
