Before buying back-office support, list the tasks, monthly volume, expected hours and approvals that remain in-house. A low hourly price does not ensure less work if briefing and corrections take substantial internal time. Customer-facing service fees are not individual assistants’ pay. For the worker perspective, see the virtual assistant guide.
Separate execution from decisions
Task | Inputs to provide | Decision retained |
|---|---|---|
Invoice preparation | Approved amounts, recipient and template | Billing and sending approval |
Data entry or bookkeeping support | Records and defined processing rules | Unclear transactions and tax judgment |
Recruitment scheduling | Availability, messages and owners | Selection and employment terms |
Document or enquiry organization | Storage, categories and response examples | Exceptions and commercial commitments |
The NTA explains reserved tax-professional services in Japan. Do not confuse routine input assistance with individual tax advice, tax representation or preparation of tax documents requiring an appropriately qualified provider.

Service / plan | Hours per month | Monthly fee, tax included | Term |
|---|---|---|---|
30 | ¥145,200 | 6 months | |
BASIC annual term | 30 | ¥132,000 | 12 months |
20 | ¥68,640 | 1 month, automatic renewal | |
PLAN30 | 30 | ¥101,970 | 1 month, automatic renewal |
Compare whether your tasks are accepted, overages, unused hours, setup, tools and cancellation notice. A year-long commitment and a one-month arrangement should not be judged on monthly price alone.

Start with one recurring process. Have the internal owner review a small completed batch, clarify the procedure and only then expand the work.
A first-month handover
Stage | Action | Check |
|---|---|---|
Inventory | Separate execution and approval | Sensitive data and required access |
Pilot | Run a small batch end to end | Acceptance and actual time |
Routine work | Increase planned volume | Escalation and verification |
Review | Assess time and corrections | Adjust scope and purchased capacity |
Control access and assess value
- Separate preparation from final payment authorization.
- Use appropriate individual access and records rather than shared personal credentials.
- Ask about subcontracting, AI tools, storage and overseas handling.
- Measure completed volume, timeliness, rework and internal review time consistently.
- Agree return of records and procedures and removal of access on exit.
Outsourcing is not automatically cheaper than employment. Compare total fees and retained management time alongside quality, continuity and the commitment you are making.
