From the person in charge of the General Affairs Division
Until we received support, our sales staff had to handle the application procedures for each customer individually.
Once you have started requesting support from an administrative scrivener corporation, we will send you the basic information and we will then take care of checking the necessary documents and outline for subsidy applications, preparing documents, managing deadlines, etc. Since we are able to advise you of any necessary measures, we are able to focus more on sales activities and customer service than before.
From the sales person in charge
They always respond flexibly to changes and irregularities within the company, which is very helpful.
The Support Administrative Scrivener Corporation handles all communication with the customer, each person in charge at our company, and the applicant, so the application process for each case was smooth and I was glad to receive such support.
You can also check the documents we prepare, so even if there are any deficiencies, you can notice them before applying, and we use this to prevent problems both inside and outside the company.
Thank you for your continued support.
