What we need for a quote
We quote each project based on its feature scope and include a scope table.
AI automation & consulting
- Industry
- The repetitive task (e.g. copying purchase orders from customer emails into an Excel order ledger each day)
- Current tools: Excel / Google Sheets / KakaoTalk / email / internal ERP or POS / other
- Frequency: daily / weekly / monthly
- What you need: review and consulting only / implementation too / decide after discussion
- Does the data include personal information?: yes / no / unsure
Mark undecided items as “unsure” or “decide after discussion.”
Steps that need human review
AI can misread or misclassify information. A person checks before amounts are confirmed, messages are sent externally or records are submitted. Legal, tax, labor and customs decisions remain with the appropriate specialists.

Frequently asked questions
Which AI do you use?
We select an AI such as Claude or ChatGPT for the task. Work that can be handled with rules alone does not use AI.
Can we send company data to an external AI?
During design, we identify the data sent outside and its processing route. Data that must not be sent is handled without AI or excluded. A specialist should review the legal basis for handling personal and confidential data; retention conditions depend on the service terms.
Can it connect to our Excel, ERP or store admin tools?
The method depends on whether the program supports integrations or file downloads. We explain in advance if a separate service account is needed, as with electronic tax invoices or KakaoTalk Alimtalk. Usage fees for AI and automation tools are set by their providers.
What happens to failed items?
Failed items are gathered separately and reported to the person in charge.
