This page covers the integration decisions that usually matter on a Epicor Prophet 21 estate, where the boundary with PIM, OMS and storefront sits, and how iWeb approaches ERP-connected ecommerce with 31 years of integration experience.

01 · Data flows iWeb integrates

Data flows iWeb integrates

Pricing and discounts
Customer-specific pricing, contracted price lists and discount rules held in the ERP and surfaced live to the storefront.
Stock and availability
Real stock by warehouse, depot, branch or yard, with safety thresholds and back-order rules honoured against the OMS.
Account ordering
Trade accounts, credit limits, approvals, statements and account-only catalogues for B2B buyers.
Orders and invoices
Orders, dispatch confirmations, invoices and credit notes flowing both ways between storefront and ERP.
Fulfilment and returns
Warehouse, branch fulfilment and returns wired into the operational systems that actually run the business.
Customers and contacts
Account hierarchies, buyer roles, addresses and contact records kept in step between ecommerce and the ERP.
Real-time vs scheduled sync
Decide what is real-time (stock, price), what is near-real-time (orders, customers) and what is scheduled (catalogue, attributes), and write it down.
Middleware and iPaaS
iPaaS, point-to-point or message-bus patterns chosen against the operation, not against a vendor preference.
Monitoring and error handling
Error budgets, retries, dead-letter queues and alerts so failed messages are seen, not silently lost.
PIM and product data handoff
Clear separation between ERP (commercial data: price, stock, hierarchy) and PIM (enriched product data: copy, attributes, assets).
Integration ownership
Named owners on both sides of the integration so incidents have a route to resolution, not a finger-pointing exercise.
Takeover and rescue
Takeover of inherited integrations: audit, stabilise, document, then improve - not a rebuild on day one.

How this trade ERP fits branch, depot and account operations.

Branch, depot and yard stock
Real stock by branch, depot or yard, with safety thresholds, reservations and held stock honoured against the trade ERP rather than approximated in the storefront.
Trade account credit
Account customers, credit limits, on-stop rules, approver workflows and account-only catalogues reflecting how the ERP actually models trade buyers.
Customer-specific contract pricing
Account price lists, contract rates, special prices and tiered discounts originating in the trade ERP and surfaced live to the storefront through a cached boundary.
Pre-7am ordering peak
The integration sized for the pre-7am trade peak, with cache strategy, queue capacity and ERP load windows tuned to how the merchant actually trades.
Click and collect by branch
Branch selection, branch-level availability, hold-for-collection and counter handoff wired against the operational systems that own them, not bolted on at the storefront.
Delivery slots and yard fulfilment
Delivery windows, vehicle constraints, yard loading and proof of delivery wired into the ERP and TMS that run the operation.
Statements, invoices, credit notes
Statements, invoices, dispatch notes and credit notes available to account customers online, posted through the trade ERP rather than re-keyed.
Reps, quotes and account orders
Reps, branch staff and account customers seeing the same prices, the same stock and the same orders, with quote-to-order flow that respects how the ERP models negotiated trade work.
EDI and merchant integration
EDI with manufacturers, buying groups and downstream merchants honoured through the existing ERP integration patterns rather than rebuilt in the storefront.
PIM and enriched product data
The trade ERP owns commercial data (price, stock, account terms); a PIM owns enriched product copy, technical attributes and assets; commerce reads from both.
Monitoring and runbooks
Queues, retries, dead-letter handling, alerts and a written runbook the on-call team can act on, so failures are seen during the morning peak, not silently lost.
Takeover of inherited integration
Inherited trade ERP integrations audited, stabilised and documented before any larger change. The first month on support is deliberately conservative on change.
04 · Questions we get asked

Questions we get asked.

What gets integrated between this ERP and ecommerce?

Pricing, stock, accounts, orders, invoices, dispatch confirmations, credit notes, customers and contacts. Exact scope is sized to how the operation actually runs the ERP.

Is the integration real-time?

Mixed. Stock and pricing are read on demand and cached at storefront read time. Orders post asynchronously through monitored queues. Reference data refreshes on a defined schedule. Cadence is tuned to ERP load.

Which commerce platforms has iWeb integrated this ERP with?

iWeb has 31 years of ERP integration experience across complex commerce estates. The integration pattern is platform-agnostic and applies wherever the architecture and integration surface support it.

Does iWeb claim a vendor partnership with this ERP?

No. iWeb is a capability provider rather than a vendor partner. The integration is built against the public surface and any agreed connectors, not against a partner badge.

Can a PIM sit alongside this ERP?

Yes. The ERP owns commercial data (price, stock, accounts). A PIM such as Akeneo owns enriched product data and channel rules. Commerce reads from both through their own connectors.

How is the integration monitored in production?

Queues, retries, dead-letter handling, alerts and reconciliation reports across storefront, middleware and ERP, with a written runbook the on-call team can act on.

What happens if the ERP is upgraded or its version changes?

The integration contract is versioned. Upgrades are scoped against the contract first; storefront-side changes follow only where the upgrade actually changes the boundary.

How does iWeb scope an ERP integration?

Discovery against the actual operational data flow, not the brochure. The integration surface, message contract, ownership and failure modes are written down before any build work begins.

Can iWeb take over an existing integration with this ERP?

Yes. The team reads the existing integration, message contracts and incident history first, then writes down what to fix first and what is safe to defer. The first month on support is deliberately conservative on change.

How are failures and dead-letter messages handled?

Every queue has an error budget, retry policy and dead-letter destination. Dead-letter items raise alerts and are triaged against the runbook rather than silently re-queued or dropped.

How is hosting and release governed?

Hosting, monitoring and the release process are tied to live trading. A named senior owner sits on both sides of the boundary so incidents have a route to resolution.

Can iWeb support multi-company or multi-territory estates?

Yes. Multi-company, multi-currency and multi-territory estates are wired against the actual ERP ledger rather than approximated, with the contract written down per company and per territory.
