Work
Company of One is an operations management platform for one-person companies, developed in-house by this Company. It covers quotations, orders, inventory, e-invoicing and VAT filing, and a test site is available to register and try.
| Item Category | Method of Implementation | Reason for Adoption |
|---|---|---|
| Audit Record Management | A hash chain mechanism is adopted: each record contains the hash of the preceding record | Should any record be altered afterwards, every record after it will fail to match |
| Quotation Confirmation | A login-free link is provided, which may be answered only once within its validity period | The client's decision is retained, together with its time and source IP, for future reference |
| VAT Form 401 Filing | No separate report tables are created; figures are totalled live from invoices and vouchers | The report and the documents will not disagree |
| Inventory Quantity Management | Totalled live from the movement ledger; no cached quantity is stored | Two contradictory figures will not arise |
IMPORTANT NOTICE: This system is currently a test site. The ECPay payment and e-invoice integrations are implemented according to the public documentation and have not yet been verified with real transactions in the sandbox; the audit chain's external witness endpoint is not yet connected; and there is at present no monitoring or alerting mechanism.

Process
-
Step 1: Confirmation of Requirement Scope
Please first describe your present situation. This Company will assist you in clarifying the problem that truly needs solving before deciding the scale of development. Unnecessary features will be proactively recommended for removal and will not be padded into the quotation.
-
Step 2: Quotation after Scope Confirmation
All quotations are calculated according to the actual amount of work. This Company charges no platform commission and adds no layers of sales markup. Please enquire with confidence.
-
Step 3: Direct Contact during Development
Progress and questions during development may be raised directly by email, without passing through a salesperson or project manager. Should requirements change, their effect on scope and cost will be explained first, and adjustments will be made only with your consent. Please feel free to entrust the matter to this Company.
-
Step 4: Delivery Includes Deployment
The method of going live will be confirmed jointly with you before quotation. Whether monitoring and subsequent maintenance are included will also be clearly stated in the quotation, in order to safeguard your rights and interests.
Services
The principal services of this Company are systems and backend development, together with website construction and deployment, covering data model design and backend API development all the way to formal launch.
AI integration, data analysis, GPU compute environments and cloud hosting are also within the scope of enquiry and discussion. However, there are at present no public cases available for reference in these areas. Please first write to describe your requirements, and this Company will reply as to whether they can be undertaken.
Individual creators who have already built a working prototype with AI but are stuck before launch may entrust this Company with only the missing part, such as database design, deployment work or a security check. Where a small or medium business's workflow still moves between spreadsheets, paper and LINE messages, this Company will first understand how you actually work at present; sometimes adjusting the workflow is sufficient and no programming is required.
