In-Depth Review TG4G Review ·2026-06-18 · For reference only

What It Is

Fimple決済 is a cloud-based billing and invoice issuance service provided by Quants Co., Ltd. It is positioned as a tool that lets businesses handle billing operations in the cloud. According to the product page, it covers registering and managing billing recipient information, creating invoices, sending billing emails, and managing follow-ups for overdue or uncollected payments. Its core selling point is that it is “completely free.”

Core Features and Collaboration

The product targets three common pain points: the time spent creating invoices in Excel, the cost of printing, enclosing, and mailing paper invoices, and missed billing or collections caused by status information not being synchronized across a team. In terms of features, users can quickly create invoices on the web, insert a company logo, and set a seal imprint. Once created, invoices can be sent directly by email, with support for checking whether they have been delivered and opened. A cloud-based list centrally displays invoice status and next actions; uncollected cases can be flagged, making it easier for teams to share information and follow up on collections.

Pricing and Onboarding

Pricing is the product’s most notable point: there is no initial fee and no monthly usage fee. The page also clearly states that there are no usage-based charges for the number of billing records registered or the number of invoices created and sent. Onboarding is not simply a matter of signing up and using the service immediately. Users must apply through the website, agree to the terms and privacy policy, register company information, undergo a review taking about 1 to 3 business days, then complete a contract before login accounts are issued.

Pros and Cons

The main advantage is its extremely low free-entry barrier, making it a potential replacement for Excel and paper mailing. Delivery/open confirmation and flags for uncollected invoices can improve payment tracking. The UI is said to be designed based on the company’s own extensive experience in outsourced billing operations. The downside is that key information commonly required for enterprise procurement—such as third-party integrations, accounting system connectivity, APIs, role-based permissions, data encryption, and compliance certifications—is not disclosed. The page mentions optional features such as anti-social forces checks, credit screening, accounts receivable guarantees, and accounts receivable purchase, but these are planned features and may be changed or discontinued.

Who It’s For and Access from China

It is better suited to local Japanese SMEs, startups, or finance/operations teams that want to digitize invoicing, send invoices by email, and manage collection status. Mainland Chinese companies issuing invoices to Japanese customers may want to assess language, contract, tax, and compliance fit. If a business mainly operates in China, it should generally prioritize local e-invoicing, tax/accounting, and ERP ecosystems. The page does not provide information about accessibility from mainland China, so this remains unknown. Payment methods are also not disclosed.
