I am currently evaluating express invoice for our small company and it works quite well. However we are located in Thailand and Google Play will not allow us to install the Android App. We are an English Language School and all our employees who would use this app are native English speakers and use up to date Samsung phones. Would it be possible to download the apk file directly (free version) and then after evaluation, if successful, the paid app? Thank you
