If you are not sure the plugin does what you need, ask. An answer that talks you out of buying is cheaper for both of us than a refund.
Email is the only channel, and that is deliberate. A message stays on record, it can carry a screenshot, and it is answered by the person who wrote the code, not by whoever is on shift.
Name and surname, qualification, address, references and other products that have been running for years. All on one page, including a button that drops the contact straight into your phone. This is the answer to what happens if the vendor disappears: the vendor has an address in Čačak and work that predates this plugin.
This is not a formality. A message with these details gets answered the first time, without three rounds of back and forth.
The most useful message you can send. Describe the business, not the feature you think you need.
The plugin has a Diagnostics page that gathers everything we need. Open it and copy the text from there.
Most of what the plugin has today came out of a message like this. Describe the problem, the solution is our job.
For anything about the key, moving to another site, and upgrading packages.
These are the questions that arrive most often, and all of them have a written answer.
A customer who asked and then bought stays. A customer who bought and then found something missing asks for their money back, and rightly so.
