Trial banner for the purpose in reminding you to pay for the product. Contribute the development for the next feature. In a way, prevent you to resale to others. If use for yourself without involving others to use. Then you won’t be feel ‘restricted’.
If pay for it. You have free reign in certain degree to brand it as a part of your service for accounting activities. No link towards manager website.
Think of it you purchase it for OEM.
There is no time limit for trial period.
I’ve been using manager server with trial period for a year learning how to manage a server and explore the possibilities in my country scenario whether manager can be use, and how well compare to other local accounting softwares. Then, I start to subscribe for annual maintenance update and purchase for the license.
In your case jorknor, you the only user using the manager server. Continue using it until the developer decide to change his approach in limiting the manager server or when you decide to have others involved using the manager server edition you hosted, it is wise to purchase the license if you do not wish other to know where you get the software. Else you doing the developer a favour for marketing. lol.
Tips: renewing the license for annual maintenance will give you substantial discount. More than 50% lol
