Mad Jester was very helpful. Now it's working everything fine, we also find some errors and there are few new PR on Github to make the plugin even better.
Now you can use SUMO for buying bios or PBE https://mining-bios.eu/ also I've set 10% discount. (There is bug, if you make order, wait for refresh it will show the right price with 10% discount, after that copy the amount, it's already in PR and will be fixed soon.)
