We compared a single central cross-dock to two regional forward stocking locations. Over a 90-day pilot, we kept the cross-dock in Columbus and opened FSLs in Dallas and Newark, routing orders by nearest inventory. Average transit time dropped from 2.5 days to 1.6 days, and peak-week cutoffs were easier to hit because each site handled smaller, local waves. What we gained was speed and elasticity: fewer split shipments and calmer afternoons because pickups were staggered. What we gave up was simplicity and inventory efficiency — more safety stock, more inter-facility transfers to rebalance, and one more carrier calendar to manage. The single cross-dock still wins when SKUs are tight, demand is steady, or oversized freight makes extra touches expensive. If you’ve run both models, which KPI moved the most for you?
What did your SLA hit rate and cost-per-order look like — did the FSLs actually beat the cross-dock once you account for replenishment and extra safety stock? We ran a similar split (ATL/PHX FSLs) and cut median transit by ~0.8 days, but carrying cost went up ~12% and split shipments got ugly until we limited FSLs to A/B movers; did you segment your catalog?
Curious what the results were: did the FSLs cut your 2- or 4-hour SLAs vs the Columbus cross-dock, and by how much? In our tests, two FSLs dropped median drive time about 38% but bumped touches and shrink; later cutoffs mattered more than anything. Did your Newark site get hammered with end-of-day spikes?
In our two-FSL pilot, 4‑hour SLA hit rate jumped from 78% to 93% and median drive time dropped about 35%, with net cost per order up about $0.40 after replenishment. Keeping only the top about 150 SKUs in FSLs and doing twice‑weekly milk runs kept safety stock lean and made peak cutoffs easier.
In our two-FSL pilot (Dallas/Newark), the 4-hour SLA hit rate moved from 80% to 95% and 2-hour from 58% to 76%, with median drive time down 36% versus a Columbus cross-dock. The trick was limiting each FSL’s same-day radius to about 45 miles and pre-positioning only the top 200 SKUs by velocity, which cut split ships and kept courier variability in check.
