I work using a Business Licence (Verslo Liudijimas) - I can issue receipts and accept payment in the following forms:
If you pay for a course by bank, please make sure you leave the following details in the information field:
Student name (if different from the person paying)
Course name (with time and month of exam if paying for IELTS - there are a lot of groups!)
e.g. Ana Šipmanaitė, IELTS 15.00 (June exam)
Thank you!
