Comparison: formulation approaches
The table below summarises common formulation strategies & their trade-offs.
| Approach | Best for | Cost implication | Common pitfall |
|---|---|---|---|
| Standard base | Launch products, test markets | Lower MOQ, faster timeline | Limited differentiation |
| Custom formulation | Brand differentiation, premium positioning | Higher development cost | Longer sampling rounds |
| Modified existing | Line extensions, seasonal variants | Moderate cost, medium timeline | May conflict with core line |
| Private label | Small brands, quick time-to-market | Lowest cost, immediate availability | Limited customisation |
| Contract packaging | Brands with own formula | Packaging cost only | Requires formula documentation |
| Fulfilment only | Established brands, volume production | Lowest per-unit cost | Minimum order quantities apply |
These are comparative ranges, not fixed values. Actual costs & timelines depend on formula complexity, pack specifications, & order volume.
