Service 2A
Make-or-buy modeling

One of the most consequential decisions in any product business — and one that most founders get wrong by defaulting to "buy from overseas" without fully understanding their real options, risks, and long-term cost structure.

We work through your specific situation, product category, volume, timeline, and risk tolerance to build a decision framework that's right for you — not a generic matrix.

💰
Cost structure
Fixed vs. variable cost across manufacturing, procurement, and logistics — modeled at your volume
🛡️
Risk & compliance
Tariff exposure, IP protection, labor law, environmental compliance — varies significantly by origin
🔧
Quality control
How much control do you need over design, materials, and production consistency?
📈
Scalability
Can your supply model grow with you — or will you need to re-source at scale?
We work through situations like these
Startup
First-time founder, limited capital
Should you manufacture domestically for quality control, or source overseas for lower unit cost? How does MOQ affect your runway? We model both and tell you the real tradeoff.
Existing business
Tariff impact on current supplier
Your landed cost just jumped 20% due to new tariffs. Do you absorb it, switch suppliers, nearshore, or start manufacturing domestically? We work through the numbers and the options.
Growth stage
Scaling beyond current supplier capacity
Your current supplier can't scale with you. Do you expand with them, find a second source, or vertically integrate? We help you think through the build vs. buy decision at scale.
FAQ
Common questions
How do I know which service (2A, 2B, 2C, 2D) I need? +
Start with where you are. If you haven't decided where or how to make your product yet, start with 2A. If you know you're buying but haven't found a supplier, 2B is your next step. If you've shortlisted suppliers and want to see them in person, 2C is your trip. If you have a deal in hand and need to review the contract, go straight to 2D. Most clients do them in sequence — but if you already have a supplier, you can start at 2C or 2D directly.
What do I need to prepare before starting? +
A product concept and a rough idea of your target price and volume is enough to get started. You don't need a detailed spec — we'll develop that as part of the process. The more you've thought through your cost constraints and risk tolerance, the faster we can move.
Do I need a supplier in mind already? +
No. The make-or-buy analysis comes before supplier selection. We help you decide where and how to source first — then Service 2B takes care of finding and vetting actual suppliers.
What's the difference between domestic and overseas sourcing? +
Domestic sourcing offers faster lead times, lower minimum order quantities, easier quality oversight, no tariff exposure, and simpler compliance — but typically higher unit costs. Overseas sourcing offers lower unit costs and more manufacturing variety, but comes with longer lead times, larger MOQs, currency risk, tariff exposure, and more complex logistics. The right answer depends on your product category, volume, margin targets, and risk tolerance — and it often isn't obvious. That's exactly what the make-or-buy model helps you decide.
What's the difference between "make" and "buy"? +
"Buy" means purchasing a finished or semi-finished product from a supplier — the most common path for e-commerce sellers. "Make" means manufacturing it yourself or with a production partner, giving you full control over specifications and costs. There's also a middle path: buying semi-finished components and doing final assembly or customization locally. Some founders start by buying and transition to making as volume justifies the investment. We help you figure out which path makes sense given your product, capital, and timeline.
Can Three Flows help if I already have a supplier but want alternatives? +
Yes. We often work with clients who have an existing supplier but want to pressure-test it — either because costs have risen, quality has slipped, or tariff exposure has changed. We model the alternatives alongside your current setup so you can make an informed decision on whether to switch, diversify, or stay put.
How is make-or-buy modeling priced? +
It's billed at $200/hour, with most engagements running between 3 and 10 hours depending on complexity. A total hours estimate is provided during your discovery call before you commit. If you're planning to proceed to Service 2B (sourcing playbook), the make-or-buy analysis can be bundled at a reduced rate — and in some cases, if you've already decided to "buy," we can skip straight to supplier identification and save you the cost.
