Passing information between systems without duplicate entry or conflicting versions

Level: PractitionerTime: 45 minutesOrder used: A (the T-shirt)Tool: Business-system role map
For an agent, or anyone coordinating between a factory's systems and a buyer's systems, who needs to pass information across a company boundary without duplicate entry or conflicting versions. The case uses Order A and only approved master figures, seen from Meridian Sourcing's own side.

This page teaches Meridian Sourcing's own team how to pass order information between Northline Apparel's systems and Delta Garments' systems without duplicate entry or conflicting versions

Meridian Sourcing acts as the agent in Egypt for two European buyers, earning a 5% commission on orders it places with factories such as Delta Garments. Every order Meridian handles crosses a company boundary at least twice: the buyer's specification and commercial approval must reach the factory, and the factory's production status, quality result and shipment information must reach the buyer. Neither side's ERP or PLM system is visible to the other, so Meridian's own hand-off is the connection between them.

If Meridian re-types figures by hand at each hand-off, or keeps its own private spreadsheet as a shadow copy of both sides' data, this course's earlier warnings about duplicate entry and version conflict apply directly to the agent's own desk. This lesson gives you a working rule for passing information across a company boundary without creating a new, uncontrolled copy of a fact that already has an owner on one side or the other.

03Before you start

What you need, and what this lesson does not cover

You need: this course's earlier lessons on what an ERP system, a PLM system and a workflow tool are each meant to control, and where specifications and commercial facts should live.

By the end of this lesson you can:

  • explain why an agent's hand-off is a transmission point, not a new system of record;
  • identify which side owns a given fact before passing it on;
  • avoid retyping a figure by hand when it could be passed through unchanged;
  • recognise when a hand-off has created an unintended second version of a fact;
  • apply the same discipline whether the hand-off is a single email, a shared file or a connected system.

Not covered here: electronic data interchange standards, API integration design, or a specific software product's import/export feature. This lesson stays vendor-neutral and focuses on the business rule.

04Key terms

Words you will meet in this lesson

TermMeaning
Hand-offThe point where information passes from one company's system or person to another's.
Single point of entryEntering a fact into a system only once, at its source, rather than re-keying it at every hand-off.
Shadow copyAn unofficial copy of a fact kept outside the systems that actually own it, usually for convenience.
Company boundaryThe point where information stops being controlled by one company's own systems and passes to another company's.
Pass-throughForwarding a fact unchanged from its source to its destination, without retyping or reinterpreting it.
Two-way traceabilityThe ability to trace a fact back to its original source, and forward to everywhere it was sent, in either direction.
05Teaching
The rule

Pass information across a company boundary as a pass-through from its owning system, not as a retyped or re-estimated copy

A hand-off should move a fact from where it is controlled to where it is needed, unchanged. It should never become an opportunity to create a second, independent version of that fact. If the buyer's approved quantity is confirmed in Northline Apparel's own system, Meridian's job is to carry that exact figure to Delta Garments, not to recall it from memory or re-confirm it informally and then treat its own recollection as equally valid.

The same applies in the other direction: production status, quality results and shipment dates are the factory's own facts, and Meridian's job is to carry them to the buyer accurately, not to summarise them from a partial understanding and let that summary become the buyer's working version.

Buyer's systemAgent pass-throughFactory's systemAgent pass-through
An agent's hand-off carries a fact unchanged in both directions; it is not a second source that may quietly disagree with either side's own system.
What you meet in real life

The hand-off point differs by role and by market, but the pass-through rule stays the same

What can differThe shapes you will meetWhy it matters
Agent between one buyer and one factoryMeridian passes the buyer's confirmed specification and commercial approval to the factory, and the factory's production and shipment facts back to the buyer.Each fact still has one owning side; the agent's role is transmission, not ownership.
Agent coordinating several factories for one buyerThe same buyer specification is passed to more than one factory; production status comes back from each factory separately.Every factory must receive the identical pass-through, and the agent must not merge or average separate factories' own facts into one figure.
Trading company buying and reselling in its own nameA trading company's own purchase order to the factory and its own resale invoice to a retailer are genuinely two separate commercial transactions, not one fact passed through.Unlike a pure pass-through, each of the trading company's own transactions needs its own controlled record in its own ERP system.
Hybrid order combining an export specification with a domestic production slotA factory may produce part of an order against an export buyer's specification and part against a domestic brand's own standing order, on the same production line.Even where two different scenario sides share a production resource, each order's own commercial and technical facts still belong to their own owning side.
Different product familiesTerry towels, home-textiles, socks and hosiery orders passing through an agent or buying office carry different technical fields, but the pass-through discipline is identical.The content of what is passed changes by product family; the rule that a hand-off should not create a new, independent copy does not.
The case we follow

Meridian Sourcing passes Order A's confirmed facts between Northline Apparel and Delta Garments without creating its own competing version

Northline Apparel confirms Order A with Delta Garments through Meridian Sourcing: 15,000 T-shirts, single jersey fabric at 180 GSM and Ne 30/1, agreed price USD 3.20 per piece FOB, with Meridian earning its 5% commission on the transaction. Northline's own commercial approval and Delta Garments' own production status never sit inside the same company's system; Meridian sits at the hand-off between them.

When Northline approves the tech pack, Meridian forwards the approved file to Delta Garments' technical team without retyping the measurements into its own separate specification sheet. When Delta Garments reports a production milestone or a quality result, Meridian forwards that fact to Northline without rounding it off from memory or waiting to batch several updates into one vague summary. Meridian's own systems track which hand-offs have happened and when, but they are not a second, competing copy of either side's specification or commercial figures.

The worked number

Order A's own commission shows why a pass-through fact and a derived fact need different treatment at the hand-off

Meridian's commission is calculated from Order A's confirmed commercial value, which is itself a pass-through fact from Northline Apparel's own approval.

Confirmed quantity (pass-through from the buyer's system): 15,000 pieces
Agreed FOB price (pass-through from the buyer's system): USD 3.20 per piece
Order value: 15,000 × 3.20 = USD 48,000
Meridian's commission at 5%: 48,000 × 0.05 = USD 2,400

The USD 48,000 order value is a pass-through fact: Meridian did not create it and must not adjust it while forwarding it. The USD 2,400 commission is Meridian's own derived fact, calculated from the pass-through value using Meridian's own agreed rate. Confusing the two — for example, letting a rounded or re-estimated order value creep into the commission calculation — would make Meridian's own invoice disagree with the commercial fact both the buyer and the factory already agreed.

GOOD: pass-through, then deriveOrder value forwarded unchangedCommission calculated separatelyBoth figures traceable to their sourceBAD: re-estimated pass-throughOrder value recalled from memoryCommission based on the wrong figureInvoice disagrees with both sides' records
A pass-through fact should reach its destination unchanged, and any figure derived from it should be calculated fresh, not blended with a recollection of the original.
The method

Hand off information across a company boundary in four steps

  1. Identify which side owns the fact — the buyer's confirmed commercial or technical approval, or the factory's own production, quality or shipment result.
  2. Forward the fact as a pass-through, unchanged, rather than retyping it from memory or a partial note.
  3. Calculate any figure the agent itself owns, such as commission, separately and traceably from the pass-through fact it is based on.
  4. Record when each hand-off happened, so both sides and the agent can trace a fact back to its source and forward to where it was sent.
The trap

A common mistake is keeping a personal running summary "to save time" that quietly becomes the version everyone actually uses

An agent handling several orders for several factories and buyers may build a personal summary sheet to keep track of where each order stands. That sheet is convenient, but if a buyer or factory starts reading figures from the agent's summary instead of confirming them against their own system, the summary has quietly become an uncontrolled second version — exactly the shadow copy this course has warned against throughout. The fix is not to stop summarising for personal tracking; it is to make sure nobody treats that summary as the source of truth in place of the system that actually owns the fact.

06In plain words

Think of an agent as a careful messenger standing between two companies that cannot see each other's systems. The messenger's job is to carry each fact across accurately, not to remember it approximately or improve it along the way. A confirmed quantity, price or specification belongs to whichever side approved it; the messenger's job is to deliver it unchanged.

Where the messenger has their own job to do — like calculating a commission — that calculation should be built freshly from the delivered fact, not from a private recollection of it. Keep personal notes for your own tracking if you need them, but never let those notes quietly become the answer other people rely on instead of the real source.

07Quick check
  • A hand-off should carry a fact unchanged from the side that owns it to the side that needs it.
  • An agent's own systems support the hand-off; they should not become a second, competing version of either side's facts.
  • A pass-through fact and a fact the agent derives from it, such as commission, need separate, traceable calculation.
  • A personal summary sheet is a convenience, not a system of record, even when it feels faster to read.
  • The same pass-through discipline applies whether one factory or several factories are involved.
  • Two-way traceability means a fact can be traced back to its source and forward to everywhere it was sent.
08Workplace scenario

Northline Apparel asks Meridian for the current production status of Order A, and Meridian only has a two-week-old note instead of today's factory update

Sara at Northline Apparel asks Meridian for Order A's current production status ahead of a planning call. Meridian's own tracking sheet shows a note from a factory update received two weeks ago, but no confirmed update since then. A team member is tempted to describe that old note as "on track, no issues" so the call can proceed smoothly.

What should Meridian tell Sara before the planning call? Decide before opening the answer.

Show decision

Confirm the current status with Delta Garments before reporting anything to Northline, rather than reusing an old note as if it were current.

1. Meridian contacts Delta Garments' own production team to get today's actual status, since a two-week-old note is not a reliable pass-through of the current fact. 2. Meridian reports the confirmed current status to Sara, clearly dated, rather than an assumption dressed up as an update. 3. If a confirmed current status cannot be obtained before the call, Meridian tells Sara honestly that the last confirmed update is two weeks old and a fresh check is in progress, rather than inventing reassurance. 4. Meridian records when each status update was received, so a future gap like this one is visible rather than hidden inside a vague summary.

Passing along an assumption as if it were a confirmed fact is exactly the kind of uncontrolled version this course has warned against — it just happens to originate from the agent's own convenience rather than from either company's system.

09What it costs

An agent passing along a stale or invented status can cost far more than the commission the order was meant to earn

Order A's agreed value and Meridian's own commission are directly derived from the confirmed figures:

Order value: 15,000 × 3.20 USD = USD 48,000
Meridian's commission at 5%: 48,000 × 0.05 = USD 2,400

If Northline Apparel makes a planning decision based on a status Meridian invented or assumed, and the real situation at Delta Garments turns out to be different, the resulting confusion, delay or corrective action can affect far more than the USD 2,400 commission Meridian earns on the order. An agent's value depends entirely on being a reliable pass-through; a single invented status update, once discovered, can cost the agent future business worth many times one order's commission.

Business-system role map: record which side owns each fact and confirm every hand-off

Use the T17-C02 Business-system role map workbook. For each fact that crosses a company boundary on an order, record which side owns it, the date it was last confirmed, and whether the current hand-off is a fresh pass-through or a stale note being reused. Start with Order A, then repeat the exercise for an order you coordinate between two companies yourself.

11Check yourself

1. When Northline Apparel's approved tech pack for Order A needs to reach Delta Garments through Meridian Sourcing, what should Meridian do with the measurements it contains?

2. Why should Meridian's 5% commission be calculated from the confirmed order value each time, rather than reusing a previously remembered commission figure?

3. Delta Garments is simultaneously producing part of an order against Northline Apparel's export specification and part against Cedar & Co.'s own domestic standing order on the same line. What is true about the two orders' commercial facts?
