How fast is 'real-time'?+
Most updates propagate in under 2 seconds, subject to marketplace API rate limits.
Can I hold buffer stock per channel?+
Yes - set per-channel buffers globally or per-SKU.
Does it handle bundles and kits?+
Yes. Component-level inventory decrements with bundle logic.
What about pre-orders and back-orders?+
Supported. Pre-orders show as future stock without blocking current sales.
Does it work with FBA + WFS + own warehouse?+
Yes - all three are tracked separately and netted for available-to-sell.
