## What you need to know

### What is ecommerce capacity planning?

Ecommerce capacity planning forecasts demand and ensures people, facilities, systems and providers can meet service objectives at acceptable cost.

### How should businesses prepare operations for growth?

Forecast workload by activity, identify constrained resources, model productivity and lead time, define thresholds and test peak operating plans.

### How do I estimate future fulfillment capacity?

Translate forecast orders and item mix into receiving, picking, packing, dispatch and return work by location, productivity and available hours.

### How do I estimate future customer-support capacity?

Forecast contacts from orders, customer mix and change events, then apply handling time, concurrency, language, hours, shrinkage and service targets.

### How do I estimate infrastructure capacity?

Use traffic and transaction forecasts, resource measurements, reliability targets, load tests, scaling behavior and provider limits with safe headroom.

### How should seasonal peaks affect capacity planning?

Plan peak-specific inventory, staffing, carrier, support and infrastructure capacity plus cutoffs, fallback procedures and post-peak recovery.

### A quick store check

Run a peak tabletop for fulfillment, support and infrastructure using forecast load, trigger points, and fallback capacity.

## Frequently asked questions

### Should capacity equal the average forecast?

No. Model variability, service targets, failure and peak demand with explicit headroom.

### Can a provider limit be treated as guaranteed capacity?

Confirm contract, quota, scaling behavior and failure modes through testing and coordination.
