A single shipment may exist simultaneously in ERP, WMS, TMS, customs software, spreadsheets, emails and carrier portals. When each location holds a different version of the cargo description, package count, ETA, cost or clearance status, the company does not lack data; it lacks data that can be trusted. Staff must re-key information, reconcile documents manually and make decisions using stale updates. This article explains how logistics data silos form, the common silo types, how to designate an authoritative source for each field and how to reduce silos without replacing every system at once.

QUICK FACTS

Definition

A data silo is information isolated by department, application or partner, so it is not shared, does not use common semantics or is not synchronised in time.

Clearest signal

The same shipment has different values in ERP, trackers, transport documents and carrier systems, with no agreed authoritative version.

Operational risk

Repeated entry, document mismatch, late declarations, poor visibility, incorrect landed cost and weak accountability.

Correct response

Do not merely centralise files; standardise identifiers, data owners, systems of record, synchronisation rules and audit trails.

SCOPE

This article applies to importers, exporters, cargo owners, forwarders, carriers, warehouses, trucking teams, customs brokers and internal departments working on the same order or shipment flow across ocean, air, road, rail and warehousing.

A silo is not limited to “systems without APIs”. It can remain after integration when parties use different SKU codes, event definitions, status models, time zones or cost semantics.

Not every separated data set is a harmful silo. Deliberate isolation for trade secrets, personal data or least-privilege access is a valid control when the data is catalogued, owned and available to authorised users. It becomes a silo when an authorised function cannot discover, interpret or use the accurate version at the required time.

KEY TERMS

Term	Meaning	Operational role
Data silo	A store of information isolated from other functions or systems.	Breaks the information chain across order, transport, warehouse, customs and finance.
System of Record (SoR)	The designated authoritative source for a data field.	Answers which value is used for declaration, payment or reporting.
Single Source of Truth (SSOT)	A controlled mechanism through which users access one trusted version.	It may combine several linked systems of record rather than one application.
Master data	Relatively stable data such as SKU, party, supplier, port, location and unit codes.	Errors propagate into bookings, documents, declarations and reports.
MDM – Master Data Management	Governance of master-data definitions, identifiers, quality and lifecycle.	Helps ERP, WMS, TMS and filing systems use approved SKU, party and location codes.
Event data	Milestones such as booking confirmed, loaded, discharged, gate-out and POD.	Creates visibility and measures elapsed time between operations.
Data owner	The function accountable for definitions, quality and approved changes.	Not necessarily the person entering data or administering software.
Audit trail	History of who changed what, when, from which source and why.	Supports investigation, controls and compliance evidence.

HOW DO SILOS FORM?

Silos do not necessarily indicate a lack of technology. They arise when each function optimises its own work: sales manages orders, procurement holds contracts, logistics tracks bookings, the warehouse uses WMS, customs staff use declaration software and finance records costs in ERP. Each application is useful, but no common data model spans the shipment lifecycle.

Technical silo: systems are disconnected and rely on files or re-keying.
Semantic silo: the same field has different definitions; for example, ETA may refer to a transshipment port in one tool and the final port in another.
Accountability silo: no one knows who may amend a field or who decides when values conflict.

Control point: an API solves transmission, not meaning or ownership. Without common identifiers and event definitions, it can distribute incorrect data faster.

COMMON LOGISTICS DATA SILOS

Silo type	Typical example	Break point	Impact
Cargo/SKU master silo	Descriptions, models, HS assumptions, weights and dimensions sit in separate files.	No shared SKU key or controlled catalogue version.	Wrong booking, origin document, label, declaration or cost allocation.
Document silo	Invoice, packing list, B/L draft, C/O and permits are held by different people.	No version-controlled shipment document set.	One document is amended while others remain outdated.
Transport-status silo	Forwarder, carrier, warehouse and trucker update separate channels.	No common event code or timestamp.	Stale visibility and late response to delay, rollover or depot change.
Cost silo	Quotation is in email, debit note in files and actual cost in ERP.	Scope, currency and cost codes differ.	Incorrect landed cost, accrual, margin and reconciliation.
Compliance silo	HS, valuation, origin, permits and explanations are personal files.	No shipment/SKU compliance repository or audit trail.	Repeated errors, weak post-clearance evidence and person dependency.
External-partner silo	Every carrier or forwarder uses its own portal, EDI or format.	Bespoke connections without common standards.	High integration cost and poor scalability.

IMPACT ON OPERATIONS AND DECISIONS

Process	Siloed data	Direct impact	Useful indicator
Booking	Cargo profile differs across sales, factory and forwarder.	Re-rating, equipment change, capacity shortfall or rollover.	Booking amendment rate; cargo-detail revisions.
Documentation	Invoice, packing list, B/L and origin documents use different versions.	Late amendments, supplementary declaration or lost preference.	Mismatches per shipment; document-closing time.
Transport visibility	Milestones are copied manually from several portals.	Outdated ETA and slow response to disruption.	Event latency; missing-milestone rate.
Customs clearance	HS, model, value and permit data are not linked.	Inspection, explanation requests and delay.	Supplementary-document rate; clearance time.
Warehouse/delivery	WMS receives late or inconsistent ETA, SKU and packing data.	Poor labour, space and equipment planning.	Truck waiting time; receipt variance.
Finance	Quotation, accrual and invoice use different cost codes.	Budget, margin, allocation and payment errors.	Invoice-dispute rate; estimate-to-actual variance.

DOCUMENTS AND DATA TO SYNCHRONISE

Data object	Source	Fields to lock	Suggested authoritative source
Order/SKU	Contract, PO, catalogue, ERP	SKU ID, model, description, UOM, quantity, specifications	ERP/MDM after procurement and compliance approval.
Cargo profile	Packing list, factory measurements	Packages, gross/net weight, CBM, dimensions, stackability, DG/OOG	Approved packing-list version.
Booking/transport	Carrier, forwarder, TMS	Booking, B/L/AWB, route, vessel/flight, ports, equipment, milestones	TMS or timestamped carrier event feed.
Customs/compliance	Invoice, classification file, permits, C/O, declaration software	HS, value, regime, origin, policy and declaration number	Approved declaration record and filing system.
Warehouse/delivery	WMS, EIR, POD and receiving report	Location, pallet/SSCC (Serial Shipping Container Code), gate events, damage and received quantity	WMS plus event evidence.
Cost	Quotation, tariff, debit note, invoice and ERP	Cost code, scope, currency, tax, accrual, actual and allocation driver	ERP/finance ledger after reconciliation.

AUTHORITATIVE DATA-SOURCE MODEL

A company does not have to replace ERP, WMS and TMS with one platform. A practical approach is to designate a System of Record for each data domain and connect them through controlled rules.

Data domain	Data owner	System of record	Consumers	Control rule
Master SKU/party/location	Procurement or Master Data	ERP/MDM	TMS, WMS, customs, BI (Business Intelligence)	Unique identifiers; approved changes.
Cargo/packing	Logistics and factory	Approved PL/TMS	Carrier, warehouse, broker	No overwrite; version and effective timestamp.
Transport event	Logistics	Carrier/TMS event store	ERP, WMS, customer portal	Common event codes, time zone and actual/estimated flag.
Customs/compliance	Compliance/Trade	Declaration record and repository	ERP, BI (Business Intelligence), audit archive	Lock source evidence and link shipment/SKU.
Financial actual	Finance	ERP/ledger	BI (Business Intelligence), costing, commercial	Mandatory cost code and shipment ID; separate estimate and actual.

SSOT is the controlled outcome of this model: users see one trusted version even though source data remains in specialised systems.

STEP-BY-STEP DE-SILO PROCESS

Step	Input	Action	Output
1. Select one workflow	For example, FCL import from PO to empty return.	Limit scope instead of starting enterprise-wide.	Process map and system list.
2. Build a data inventory	Fields, files, APIs, emails and portals.	Locate creation, copying and amendment points.	Field catalogue and duplication map.
3. Lock identifiers	PO, shipment, container, SKU, party and location.	Create common keys and legacy mapping.	Cross-system identifier set.
4. Assign owners and SoR	Field catalogue.	Assign accountability and authoritative sources.	Data ownership matrix.
5. Standardise semantics	Field names, units, events, time zones and statuses.	Create a dictionary and common code lists.	Common data model.
6. Design integration	API, EDI, files, queues and manual fallback.	Define direction, frequency, validation and exceptions.	Integration and exception map.
7. Measure and scale	Mismatch, latency, completeness and duplicates.	Fix root causes before adding routes or partners.	Quality dashboard and rollout plan.

RISKS AND COMMON MISTAKES

Mistake	Cause	Impact	Control
Buying a data lake before standardisation	Technology-first approach.	One large repository containing conflicting versions.	Define dictionary, owner and SoR first.
Uncontrolled bi-directional sync	Both systems can overwrite each other.	Loops and untraceable changes.	Master–consumer and conflict rules.
Using product name as a key	Names vary by document and language.	Duplicate or wrongly linked SKU records.	Use stable IDs; names are attributes.
No document versioning	New files overwrite old files.	No evidence of what existed at filing time.	Version, timestamp and approval log.
Measuring only API uptime	Interface works although data is late or wrong.	Green IT dashboard but continued re-keying.	Measure completeness, accuracy, latency and exceptions.
Ignoring access control	Broad access is used to break silos.	Commercial-data leakage or unauthorised edits.	Role-based access, least privilege and audit trail.

STANDARDS AND REFERENCE SOURCES

These sources support interoperable design and common data semantics. They do not replace internal procedures, partner contracts or legal requirements applicable to specific data.

Source/standard	Role in breaking silos	Application limit
DCSA Track & Trace	Uses interoperable data models, standardised definitions and APIs to exchange container-shipping events across platforms.	Focuses on container transport; it does not govern internal master data, documents or costs.
DCSA – Portbase interoperability	Illustrates federated sharing in which participants retain control while exchanging data through common standards and governance.	An ecosystem implementation lesson, not a mandatory technical specification.
UN/CEFACT Reference Data Models	Provides common semantics and reference models for Buy–Ship–Pay and multimodal transport processes.	Must be mapped to the company’s fields, code lists and operational processes.
GS1 Standards	Provides a common language to identify, capture and share product, location and logistics-unit data.	Works only when identifiers are governed consistently across parties.
GS1 EPCIS/CBV 2.0.1	Standardises event data and semantics so applications can share status, time, location and business context.	Does not correct inaccurate source data or replace operational systems.

FAQ

Will one shared spreadsheet remove silos?

No. It can reduce dispersion but usually lacks scalable validation, access control, event integration and reliable versioning.

Must ERP always be the only source?

No. ERP may own master and finance data; carrier/TMS may own transport events, while WMS owns warehouse status.

Are a data warehouse and SSOT the same?

Not exactly. A warehouse is storage/analytics architecture; SSOT is the governance principle defining the trusted version.

Will an API remove manual entry?

Only when identifiers, schema, validation and exception processes are agreed. Otherwise staff still repair integrated data.

Where should a company start?

Choose one costly flow, such as PO–booking–customs–delivery, and lock the limited set of fields driving decisions.

Must legacy software be replaced?

Not necessarily. Specialised applications may remain and be connected through master data, integration and event layers.

Which KPIs show improvement?

Re-keying, document mismatch, event latency, supplementary filing, invoice disputes and decision lead time should decline.

APPLICATION NOTE: Data architecture must reflect cargo type, mode, current systems, partner roles and information-security requirements. Do not broaden access or automate sensitive-data exchange without assessing permissions, retention and applicable legal obligations. Vietnamese-law references, where any are added later, should be checked in the official Vietnamese text.
