A range review that ignores maintenance schedule will often produce a confident decision and a disappointing quarter on the Smooth 4.
Seasonality interacts with maintenance schedule more than most forecasts allow for, so a rolling review beats an annual one.
Why maintenance schedule matters on the Smooth 4
Regular cleaning of contacts prevents most intermittent faults.
Freight consolidation changes the answer to maintenance schedule at container scale, which is why small and large buyers reach different conclusions.
Coil replacement intervals depend on liquid sweetness and usage intensity.

Where two suppliers look identical on price, maintenance schedule is usually the variable that separates them over a full year.
Checklist
- Agree in advance who pays for return freight on a defect claim.
- Record the arrival condition with photographs on the day of delivery.

Commercial terms
Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

|---|---|---|
| Carton (152 units) | Tier 1 | 21-30 days |
| Pallet (661 units) | Tier 2 | 14-21 days |
| Container (8877 units) | Tier 3 | 30-45 days |
Frequently asked questions
How often should Smooth 4 be cleaned?

How quickly can a repeat order be produced?

Can several models be mixed in one shipment?
Yes, mixing models and flavours within a carton or pallet is common and usually helps first time buyers test demand.

Final word
A short quarterly review of these points will keep the Smooth 4 range healthy without consuming the week.
