OMS · Inventory

Inventory & order management built for omnichannel reality

Run every line of demand—from marketplace SLAs to warehouse picks—in one system of record. Support Master OMS ties channels, stock positions, customer promises, and financial expectations together so operations scales without losing control.

At a glance

What teams evaluate first when scoring an enterprise OMS on Support Master.

  • Multi-channel order normalization & lineage
  • ATP, soft reservations, and allocation rules
  • Exception queues, SLA risk, and cancel/replace flows
  • Returns, RTO, and partial fulfillment states
  • Warehouse / 3PL pick, pack, and handoff visibility
  • Audit trails tie actions to users and systems

Foundations

Three pillars operators feel on day one

These capabilities are how brands stop reconciling five sources of truth every Monday morning. Each pillar is configurable to your node structure, channel contracts, and governance rules—not a forced “one size” workflow.

Unified order operations

Give headquarters and hubs one place to see demand as it actually exists: new, confirmed, allocated, shipped, delivered, returned, or disputed. Slice by channel, brand entity, warehouse, carrier lane, payment state, or SLA clock—without exporting five consoles into a spreadsheet. Line-level history shows what changed, who changed it, and which integration or user initiated it, so root-cause conversations after peak weekends take minutes instead of days.

Multi-location inventory truth

Model fulfillment nodes the way you run the business: stores, dark stores, regional DCs, cross-docks, and partner 3PLs. Channel-specific available-to-promise respects buffers, safety stock, and “do not sell” assortments. Transfers, ASN expectations, and cycle-count variance can feed the same stock ledger your listings read from—reducing oversell events and emergency channel shutdowns during promos.

Sync that survives peak

Connect marketplaces, aggregators, D2C storefronts, POS, and ERP through a deliberate sync strategy: webhooks where reliable, polling with backoff where not, and reconciliation jobs that realign drift before it hits customers. Rate-limit awareness and idempotent updates help during traffic spikes so order state and quantity on hand stay directionally correct when everyone is running flash sales at once.

Order lifecycle

From capture to settlement—one thread, many teams

The same order object carries context for merchandising, warehouse, carrier relationships, CX, and finance. Handovers are explicit; nothing is “assumed” in a side email.

  1. 1

    Capture

    Ingest orders from every selling endpoint with normalized addresses, tax hints, fees, and promised dispatch windows mapped to your internal SLA classes.

  2. 2

    Validate & allocate

    Fraud checks, payment authorization alignment, and allocation against ATP—with reservations that respect channel priority and regional commitments.

  3. 3

    Fulfill

    Release picks, wave batches, carrier manifests, and handoffs to 3PL or store fulfilment with status callbacks into the same timeline sales and support see.

  4. 4

    Deliver & support

    Track in-transit milestones, delivery proof, and customer contacts. Surface delay risk early for proactive outreach.

  5. 5

    Settle & reconcile

    Close the loop with marketplace settlements, COD remittance patterns, and return credit expectations so finance does not re-build the month in Excel.

Inventory depth

Stock logic that matches how you merchandise and fulfill

Whether you are shelf-stable retail, high-velocity marketplaces, or hybrid food + ecommerce, the inventory engine must respect how you segment catalog and fulfillment—not flatten everything to one global “qty.”

ATP & reservations

Hard and soft reservations, channel carve-outs, and “ship from” ranking so you protect strategic partners without starving D2C during stock shocks.

Transfers & inbound

Planned movements between nodes with expected availability dates—so merchandising knows when to push stock live on a shelf or a marketplace.

Kits & bundles

Explode bundle demand to components and block sales when any line is constrained—reducing partial picks and CX apologies.

Lot / expiry (where used)

Optional constraints for regulated or fresh categories; FEFO-friendly allocation guidance for teams that need it.

Exceptions

Designed for the 10% of orders that consume 80% of attention

Peak season and promos do not fail on the happy path—they fail on edge cases. OMS workflows here are built so humans intervene with context, not rebuild state from scratch.

Address & contact fixes

Controlled edit paths with rules on when a change is allowed pre-pick vs post-handoff, and automatic notifications to carriers or marketplaces where APIs support it.

Cancellations & replacements

Reason-coded cancellations with inventory release rules; substitute-SKU suggestions grounded in what you actually have allocatable.

Returns & partials

RMA creation linked to original shipments, refund or credit workflows, and restock disposition so stock accuracy recovers after the box is opened.

SLA breach prevention

Queues ordered by dispatch risk, not just FIFO—so ops clears what will miss customer promise first.

Governance

Roles, approvals, and auditability by default

Enterprise operators need to know who can cancel at what margin, who can override inventory, and what happened when finance asks three months later. Support Master separates admin, brand, warehouse, and agent workspaces with permission matrices that tie back to the same order and inventory events—so internal controls and external audits stay tractable.

Integration posture

ERP remains the ledger of record where you want it; Support Master orchestrates operational velocity on top. Webhooks, batch exports, and idempotent APIs align with how your integration team already ships changes—see integrations for typical patterns.

Metrics you can instrument

  • · Dispatch SLA adherence by channel and region
  • · Fill rate, oversell incidents, and allocation latency
  • · Exception aging and first-touch resolution time
  • · Return and RTO rates segmented by cohort (for AI handoff later)

Who it serves

Aligned incentives across the operating org

V

VP / Head of operations

Single health view across regions and channels; confidence that exceptions surface before they hit NPS.

F

Fulfillment lead

Reliable pick lists, batching, and 3PL handoffs—with fewer “why is this still unshipped?” escalations.

M

Marketplace manager

Listings, fees, and SLAs in the same order object the warehouse uses—no parallel spreadsheet truth.

C

Customer support & agents

Full timeline, notes, and guardrailed actions so first-contact resolution and QA reviews are straightforward.

FAQ

Common OMS evaluation questions

Do we have to replace our ERP?

No. Many customers keep the general ledger and financial posting in ERP while Support Master owns high-velocity order and inventory orchestration. The boundary is defined during design so postings and cutoffs stay clean.

How do you handle marketplace-specific rules?

Channel profiles encapsulate SLA classes, cancel windows, shipping label expectations, and fee attributes so operators are not re-learning each console’s quirks inside a generic grid.

What about oversell during extreme spikes?

Buffers, reservation timeouts, and reconciliation jobs reduce drift; combined with alerting, teams can throttle listings or reallocate before a wave of cancellations damages seller health scores.

Can stores and DCs fulfill the same SKU set differently?

Yes. Node-level assortment, ship-from priority, and channel eligibility let you route demand to the right inventory pool without duplicating SKUs in multiple systems.
