The 9 steps, start to finish

The 9 steps, start to finish

From first idea to ongoing supply — here’s the whole journey, one step at a time. Each guide shows the common pitfall and how you can self-check, before you commit a dollar.

1

Define your needs

Pitfall: a vague brief lets suppliers steer you toward their stock items. Self-check: pin down form, dose, and target market before you request quotes.

2

Vet suppliers

Pitfall: trading companies often pose as factories. Self-check: ask for the business license and real production photos, then verify the entity behind the quote.

3

Raw materials & extracts

Pitfall: COAs can be edited or backdated. Self-check: request batch-specific test reports from a third-party lab that you name.

4

Formulation & dosage form

Pitfall: a “same as the competitor” formula may be illegal in your market. Self-check: confirm the active form and claims are permitted where you sell.

5

OEM / private label

Pitfall: hidden MOQ and tooling fees appear after you commit. Self-check: get the full cost breakdown and re-order terms in writing, up front.

6

Manufacturing & QC

Pitfall: a “GMP” sticker without a real audit. Self-check: ask for the certificate issuer and a recent, dated inspection record.

7

Compliance & certification

Pitfall: assuming one certificate covers every market. Self-check: list your target markets and confirm exactly which certs each one requires.

8

Inspection, payment & logistics

Pitfall: paying 100% upfront removes your leverage. Self-check: tie payments to inspection milestones and use escrow where possible.

9

After-sales & supply continuity

Pitfall: a single-source supplier can stall your whole business. Self-check: qualify a second source and agree on lead times and buffer stock.
