Onboard a new 3PL or co-manufacturer
without losing track of a single unit

Adding a warehouse partner should take days, not a quarter of manual file uploads and two versions of the truth. DOSS connects the new location, maps your SKUs and lots to it, and reconciles inventory continuously, so your team keeps running on one live number from day one.

What onboarding a 3PL usually looks like

  • Weeks of CSV uploads and re-keyed SKUs before the first order ships.

  • Two inventory numbers for months: the 3PL portal's and your spreadsheet's.

  • Order routing rebuilt by hand, and every exception lands in your inbox.

How it works in DOSS

  1. 01

    Connect the location

    Native connections to ShipHero, ShipBob, Stord, Extensiv, and other 3PL systems, or EDI/API for co-mans, bring the partner online without a custom integration.

  2. 02

    Map SKUs, lots, and costs

    Unified Master Data carries your products, BOMs, and landed costs to the new location, so nothing is re-keyed.

  3. 03

    Set routing rules

    Decide which channels and regions ship from where; DOSS routes orders and re-routes on stockouts automatically. Run both providers side by side during a transition, split volume, or roll back.

  4. 04

    Run on one number

    Inventory reconciles continuously across every location, with exceptions surfaced for review instead of discovered at month-end.

One inventory number across every warehouse, 3PL, and co-man

On-hand, committed, and available by location are live in one view, down to the lot. Counts from the 3PL reconcile against yours automatically, and variances post as adjustments with an audit trail.

Orders route to the right location without a rulebook in your head

Routing rules live in DOSS, not in a spreadsheet. Split shipments, regional fulfillment, and stockout re-routing happen automatically, and every order shows where it shipped from and why.

Co-man production that flows straight into inventory

Send POs to a new co-man, and when the production certificate or BOL comes back as a PDF, Dossbot reads it and creates the lot with its yield and cost data. Storage, pick-and-pack, and freight roll into landed cost per unit per location, so you can compare partners on margin, not the rate card.

Frequently asked questions

Connect the 3PL's system, map your SKUs and locations to it, set routing rules, and reconcile inventory against their counts. DOSS handles each of these as configuration, so a new 3PL gets order routing, inventory sync, and shipment tracking from day one.

Yes. DOSS can split order volume between the old and new provider during a transition and roll back if needed, while keeping one inventory ledger across both.

DOSS pulls each 3PL's inventory snapshot daily, compares it to its own ledger, and flags variances for review and cycle counts.

DOSS sends POs to the co-man, receives production runs with lot numbers, yields, and costs by API or AI-parsed documents, and rolls co-man charges into landed cost.
