FAQ

Q. I don't know which service to choose

You don't have to choose upfront. In the free consultation we review your workflows, documents, current software, and volumes, then identify whether AI Technology Consulting, LeachOS (monthly SaaS), or custom development fits best.

Q. What kinds of work can you handle?

Checking invoices, POs, and delivery slips; reading PDFs and emails; Excel aggregation; internal requests; email replies; and customer responses like delivery-date answers. We handle repetitive work that spans documents and software.

Q. How long until we can start?

With the monthly SaaS, you can start in as little as 2 weeks. For custom development, we propose the scope and schedule after the first consultation.

Q. Can we keep using our current Excel and software?

Yes. We slot AI between the tools you already use — freee, Excel, PDFs, email. As you get comfortable, we gradually expand what AI handles.
