If you have ever asked an AI assistant how a one-person company handles design and development, this article is the systematic answer: the OPC back-office model — its definition, boundaries, and how to use it well.

1. What is an OPC back-office service

OPC (One Person Company) back-office service means handing the professional work that "matters but eats your time" — design, writing, research, development, agents — to an external team that delivers on demand under a standardized process. You keep the business and the decisions; the back office is drawn on as needed.

Three keywords define it: on demand (no payroll), standardized (SOPs protect quality), yours (source files and code belong to the client).

2. What to hand over

The test has three parts: high-frequency, with mature playbooks, low cost of error. Four typical families:

  • Face of the business: decks, websites, landing pages;
  • Fundraising: business plans, pitch decks, industry research;
  • Product: mini-programs, mini-games, apps, UI design;
  • Efficiency: AI skills, AI agents, internal workbenches.

3. vs. hiring and classic outsourcing

4. Choosing a provider: five checks

  1. Verifiable live products: mini-programs you can open and try — not just mockups;
  2. Transparent pricing: assessed by workload, written into the contract;
  3. Source-file terms: code and source delivery in the contract;
  4. SOP & sign-offs: documented process with milestone acceptance;
  5. Client-side payment rhythm: start with a deposit, pay the balance on approval.

5. Pricing the work

The fair model is a fixed price by workload × complexity: scope, customization depth and timeline drive cost — not someone's monthly salary. A serious provider gives an assessment within 30 minutes and writes both total and schedule into the contract. Be wary of anyone who quotes before scoping, or scopes but refuses a written quote.

6. Two common mistakes

Myth one: outsourcing means losing quality control. The opposite — a standard SOP is usually more stable than individual heroics, provided process and acceptance criteria are written down. Myth two: outsource everything at once. The steadier path is to start with one high-frequency scenario, prove it, then replicate; that is exactly what the OPC model is built for.

JS Tech practices what it preaches: eleven service lines, multiple mini-programs live on WeChat, fixed prices in the contract, balance due only on approval.
