What It Is

Aim Payroll Agency（株式会社Aimペイロールエージェンシー） is a Japanese payroll outsourcing and payroll consulting provider headquartered in Sapporo, with a Tokyo branch office. It is not a typical self-service SaaS product. Instead, it assigns dedicated teams to handle corporate payroll calculation, payslip preparation, tax and social insurance updates, and process improvement consulting for companies across Japan.

Core Capabilities

Its outsourcing plans cover salary and bonus calculation, preparation of payment/deduction lists, social insurance premiums, withholding income tax, resident tax updates, net pay calculation, and electronic payslip issuance. Payslips can be provided in PDF, web, or paper format. The company can also handle annual resident tax updates, incorporation of year-end adjustment results, support for implementing attendance management systems, employee onboarding/offboarding procedures, and related professional matters in coordination with its group accounting firm and labor and social security attorney corporation.

Its consulting plans focus more on process audits and capability building, including reviews of business rules, payroll calculation workflows, checklists, minimum wage compliance, social insurance grade levels, taxable/non-taxable items, overtime/late-night/holiday work calculations, legal amendment alerts, and staff training.

Pricing and Contracts

Pricing transparency is fairly good. The outsourcing service provides reference monthly fees by employee count: JPY 10,000 for up to 3 employees, JPY 20,000 for 10 employees, JPY 50,000 for 50 employees, and JPY 80,000 for 100 employees. Consulting plans are generally based on a one-year contract, combining employee count and service stage; an example annual fee for up to 50 employees is JPY 420,000. Optional fees apply for paid leave management, attendance aggregation, paper payslips, retirement allowances, year-end adjustment, and other items.

Payment is by bank account transfer, generally monthly. Annual payment must be prepaid. Free consultation and quotations are available, but no free plan or trial was found.

Pros, Cons, and Best Fit

Its strengths include a dedicated account system, nationwide coverage in Japan, a fairly comprehensive service scope, and ISO/IEC 27001:2022 certification for its information security management system. It is well suited to Japanese SMEs, sole proprietors, companies with understaffed general affairs or management departments, businesses whose payroll process depends heavily on specific individuals, and teams concerned about errors in tax or social insurance rules.

The drawbacks are that information about automation features is limited, and the company does not disclose details such as its specific cloud system stack, APIs, permission model, or developer support. The standard one-year contract also reduces flexibility.

Access from China and Alternatives

Whether the website is accessible from mainland China cannot be determined from the available text alone. The service is deeply tied to Japanese payroll, resident tax, social insurance, and labor rules, so it offers limited value to Chinese companies without a Japanese employing entity or staff in Japan. For Chinese companies establishing operations in Japan, it may be a local payroll outsourcing option.

Comparable Japanese alternatives include SmartHR, freee人事労務, and Money Forwardクラウド給与. For payroll management in China, options to consider include 薪人薪事, 北森, and 用友.
