Automate the 1P journey end-to-end:
- PO ingest → acknowledgement → pick/pack (SSCC) → ASN → invoice → payment advice & deductions.
- Run it in your own DC or 3PL, keep Sage 200/NetSuite/SAP Business One tidy, and cut chargebacks.
Who this page is for
- Brands and manufacturers supplying Vendor Central (1P) in the UK/EU/US
- Ops teams needing ASN + label accuracy, on-time appointments, and clean PO-to-cash
- Finance teams wanting payment advice import, deductions visibility and faster ERP reconciliation
What you’ll get (at a glance)
- Zero re-keying from PO to invoice
- ASN / label compliance (SSCC carton & pallet)
- Chargeback reduction via validation and evidence packs
- Faster despatch with barcode-driven pick/pack
- Cleaner AR with automatic payment advice import & deduction flags
- ERP-first posting to Sage 200 / NetSuite / SAP Business One
Cloud-first & resilient: Modulus keeps running even if your ERP is offline, queuing events and syncing back with an audit trail once it’s online.
How it works (end-to-end 1P flow)
- PO ingest (ORDERS / 850) → Create sales orders with destination FC and pack requirements
- PO acknowledgement (ORDRSP / 855) → Accept, accept with changes, or reject based on ATP/pack rules
- Routing (Collect vs Prepaid) → Submit routing details; capture routing IDs & appointments
- Pick & pack → Wave/cluster picking, cartonisation, SSCC generation, carrier labels
- ASN (DESADV / 856) → Transmit carton contents and SSCCs; validate against booking
- Invoice (INVOIC / 810) → Post invoice in the ERP; transmit to Amazon incl. allowances
- Payment advice & deductions → Import settlements; surface shortages/chargebacks for dispute with evidence
ERP integrations
- Sage 200 — SOP Order → SOP Despatch Receipt → Post to Invoice; analysis codes, VAT & nominal kept intact
- NetSuite — Sales Order → Item Fulfilment → Invoice; Locations/Bins, packages & ASN data aligned
- SAP Business One — Sales Order → Delivery → A/R Invoice; supports UDFs & bin locations

Chargeback prevention baked in
- Validation pre-send — ASN & label checks before transmit
- Window compliance — plan picks to FC window & routing
- Fill-rate tracking — ORDRSP logic for short-ships/substitutions
- Price/allowance checks — highlight mismatches before invoice
- Evidence packs — labels, carrier files, despatch & ASN proof in one place
Always-on resilience (ERP-independent)
- Store-and-forward queue
- Automatic retries & replay
- No warehouse downtime (scanning & labels continue)
- Health status & alerts
- Event-level audit trail
Implementation timeline (typical)
Week 0–1 — Connect & model
- Connector setup, VC endpoint config (EDIFACT/X12)
- Item cross-refs, FC models & label templates
Week 2 — Flows & compliance
- ORDERS → Order creation, ORDRSP policies
- Pick/pack with SSCC; DESADV & labels validated in staging
Week 3 — Reconciliation & edge cases
- Payment Advice import; shortages/chargebacks workflow
- Split shipments, mixed cartons, multi-PO pallets
Go-Live (Week 4)
- Pilot FC → scale, dashboards & hypercare
Results to expect
- 40–60% fewer chargebacks (ASN timing & cartonisation accuracy)
- 2× faster PO-to-despatch with wave/cluster picking
- Cleaner AR via payment advice matching & deduction flags
Case study snapshot
“We consolidated 1P VC on Modulus365 with Sage 200. Chargebacks down 42%, cut-off moved 60 minutes later, and month-end AR reconciliation shortened by two days.”

Amazon Vendor Central — Frequently Asked Questions
Do you support routing requests for Amazon collect?
Yes — we submit routing details, store routing IDs, and tie them to ASN/shipment records.
Can you generate SSCC carton & pallet labels?
Yes — GS1-compliant SSCC labels are generated at pack time and included in the ASN.
What happens if Amazon changes the delivery window?
Modulus re-sequences picks and updates carrier/appointment data; the ASN reflects the new schedule.
How are deductions handled?
We import payment advice, surface shortages and chargebacks, attach evidence for disputes, and post entries back to the ERP.
Do you support EDIFACT and X12?
Yes — EDIFACT (ORDERS/ORDRSP/DESADV/INVOIC) and X12 (850/855/856/810) are supported.
Can a 3PL fulfil Amazon VC for us?
Yes — we can push VC orders to a 3PL; SSCC, labels and ASN still originate from Modulus.
