Customer Portal · Perai Industrial Estate
Give each verified buyer the approved engineering revision and its dispatch evidence without exposing obsolete drawings or internal costing.
Illustrative Perai engineering-supplier collaboration scenario. No pictured customer, tenant, order, drawing or delivered EC TECH portal is real or claimed.
A Perai customer-collaboration starting point
A Customer Portal for an engineering supplier in Perai Industrial Estate can start with one sheet-metal enclosure order. A revised drawing has been approved internally, an older version still appears in a customer-facing request, and a dispatch crate is being prepared. The portal should prove the buyer’s entitlement, identify the effective approved revision, record acknowledgement and connect dispatch proof to that exact version.
InvestPenang lists Perai Industrial Park in Penang’s industrial network. That is useful location context, not evidence about any particular tenant’s document controls or customer contract. Discovery should use approved sample drawings, a withdrawn revision and a customer clarification to test access and correction behaviour.

Where to begin
Start with repeated work that takes time, depends on scattered information or waits for the same decisions again and again.

Mark the withdrawn version and direct the account to the current authorised record.
Enforce organisation, user, order and revision entitlement on every request.
Keep proposal, internal approval and customer acknowledgement as separate states.
Tie shipment evidence to the same order, part and effective drawing version.
Practical delivery process
Test withdrawal of an obsolete drawing and wrong-account access, not only a successful document download.

Confirm account, user role, order and part before exposing a customer document.
Distinguish proposed, approved, superseded and withdrawn drawing states.
Have a named document owner clear customer-safe content and separate internal costing.
Record which approved revision the entitled buyer saw and whether a clarification remains open.
Attach shipment evidence to the exact order, part and effective drawing version.
Notify the right audience when an earlier file must be replaced, without erasing its audit history.
One buyer, one approved revision
The decisive hand-off is which drawing and dispatch record the buyer may see, and what stays internal.

A supplier collaboration room links an enclosure prototype, approved sleeve and dispatch crate.

A macro review catches an older drawing still attached to a customer request.

Six tangible objects test buyer identity, revision, approval, private cost, dispatch and clarification.

Before and After retain the same controller, buyer, enclosure, three sleeves, tablet and crate; only the disclosed record changes.
A pilot should demonstrate correct-document access and correction history, not treat a download as engineering acceptance.

At the same collaboration table, the buyer tablet displays an obsolete amber drawing while internal cost notes sit too close to the customer side.
The same people and objects remain; the buyer sees the blue approved drawing, the obsolete sleeve is withdrawn and cost notes stay internal.
Engineering-supplier customer access in Perai
InvestPenang identifies Perai Industrial Park. The pictured enclosure, supplier room and buyer are fictional; no specific Perai tenant, EC TECH client or delivered project is asserted. Actual drawings, contract terms, customer permissions and retention rules must come from authorised owners.
A customer portal should not flatten draft, proposed, approved, superseded and withdrawn drawings into one file list. It must enforce audience and order scope, keep internal costing on the supplier side and connect any dispatch evidence to the effective revision. Acknowledgement of receipt is not automatically contractual acceptance.
EC TECH can scope a redacted pilot: approve one revised drawing, deny an obsolete link, keep the internal cost binder private, record buyer acknowledgement and attach dispatch proof to the right version. This differs from the Batu Kawan portal example, which centres inspection-report supersession and a return question.
