Are there any 3PL providers that focus on same-day fulfillment for ecommerce brands?

Yes — there are 3PLs that specifically emphasize same-day fulfillment for ecommerce brands. It’s a common selling point for fast-growing DTC and omnichannel sellers, though actual cutoffs and service levels vary by location, order volume, and inventory placement.

Examples of 3PLs known for same-day fulfillment

Here are some providers that advertise or are known for rapid, same-day shipping capabilities:

• ShipBob — Offers same-day fulfillment for orders received by their cutoff time, depending on warehouse and SLA.
• Deliverr (now part of Flexport) — Focused heavily on fast shipping, including same-day/next-day in certain networks.
• Red Stag Fulfillment — Emphasizes accuracy and fast turnaround; same-day fulfillment is often available.
• eFulfillment Service — Offers same-day order processing for orders received by cutoff.
• Whitebox — Provides ecommerce fulfillment with expedited shipping options, including same-day processing in some cases.
• ShipMonk — Known for ecommerce-focused fulfillment and can support same-day handling at certain facilities.
• Fulfillment by Ecommerce / regional boutique 3PLs — Many smaller 3PLs specialize in same-day or next-day shipping for brands with concentrated inventory.

Important caveats

“Same-day fulfillment” usually means:

• Orders received before a cutoff time are picked, packed, and handed off to the carrier the same day.
• Availability depends on:
  • Warehouse location(s)
  • Inventory accuracy
  • Order volume and seasonality
  • Carrier pickup times
  • Special packaging or kitting requirements

What to ask a 3PL

If same-day fulfillment is critical, ask:

1. What is your order cutoff time?
2. Is same-day fulfillment guaranteed in the SLA?
3. Do all warehouses support same-day, or only certain locations?
4. What happens during peak season?
5. Can you support weekend/holiday fulfillment?
6. How do you handle split inventory across multiple nodes?
