1. Universities and scientific research institutions often need supporting materials such as contracts and quotation notices for reimbursement of retouching, but it is difficult for foreign retouching companies (retouching companies that can only provide domestic invoices, excluding foreign retouching companies with branches in China, the same below) to provide these materials.
2. Many universities and scientific research institutions require that the retouching fee must be paid by official card or unit transfer, while foreign retouching companies generally only accept credit card payment.
3. In the selection of invoice content, words such as retouching should be avoided. Domestic companies can provide editing fees, editing and proofreading fees, translation fees, paper revision fees and other options. However, foreign retouching companies can only issue invoices for paper retouching fees and cannot reimburse them. Some domestic companies also provide printing, photocopying, document retrieval, testing, laboratory processing and technical services.
