# [Your Marketing Systems Don’t Need to Speak the Same Language. They Need a Common ID.](https://blog.shopperations.com/your-marketing-systems-dont-need-to-speak-the-same-language.-they-need-a-common-id)

If you work in CPG marketing, this scenario will probably sound familiar. Your team has a marketing plan. Your agency has its own planning system. Finance has an ERP. Sales may have a TPM system. Your retail media partners each have their own platforms and portals. Coupon and incentive programs are tracked by clearinghouses. Invoices, deductions and actual spend live somewhere else. Performance data arrives from yet another collection of sources.

Each system may work perfectly well for the job it was designed to do. The problem starts when you want to connect them.

A campaign that your marketing team calls “Walmart Back to School” might become “WM BTS FY27” at the agency. Finance knows it as PO 450028371. A retail media platform assigns Campaign 9837264. A clearinghouse gives an offer yet another identifier. Eventually someone asks a seemingly simple question: “What did we actually spend on Back to School, and what did we get for it?”

Suddenly, five people are downloading spreadsheets and trying to figure out which records belong together. This is usually where someone says, “We need better integrations.” Maybe. But integration alone doesn’t solve the underlying problem.

 

## **Before you integrate your systems, define your data**

CPG companies have accumulated an impressive collection of specialized technology. ERP systems manage financial transactions. TPM systems manage trade promotion. Agencies have tools for media planning and buying. Retail media networks have campaign platforms. Clearinghouses track coupons and incentives. Data warehouses aggregate information. BI platforms visualize it.

The problem is that each system has its own purpose, its own data structure and its own nomenclature. The retailer sees the world differently from your agency. Your agency sees it differently from Finance. Finance sees it differently from the shopper marketing team.

Trying to make every system speak exactly the same language is an enormous undertaking, and usually an unrealistic one. IT teams already have long queues of higher-priority projects. Custom integrations are expensive to build and maintain. Vendors change. Agencies change. Platforms change. Even your own organizational structure changes.

There is another way to think about the problem.

Before asking, “How do we integrate all these systems?” ask, **“What is our marketing data model?”**

Your company should decide how it wants to describe its own marketing activity. What dimensions matter for planning and decision making? Brand? Customer? Market? Fiscal period? Campaign? Tactic? Channel? Funding source? Product? Objective? Agency? Your nomenclature should reflect the way your business actually plans, manages and analyzes marketing, rather than being dictated by whichever external system happens to be involved in the next step. In other words, **own your nomenclature first,** then give every marketing activity an identity.

 

## **A unique ID is more powerful than it looks**

Unique IDs sound like database plumbing, which may explain why marketers rarely get excited about them. But a persistent unique identifier can become the connective tissue for an otherwise fragmented marketing technology ecosystem. Think of it as a passport for a marketing activity.

When an activity is first created in your marketing system of record, it receives an ID. That ID does not need to replace all the other identifiers that will eventually be associated with the activity. Finance can still assign a PO number. A retail media platform can assign a campaign ID. A clearinghouse can assign a Coupon Offer ID. An agency can use whatever naming convention works for its workflow. The marketing activity's unique ID simply travels with it.

That distinction is important. Your systems do not have to agree on what to call something. They just need a reliable way to know that they are talking about the same thing.

Consider one marketing activity as it moves through its lifecycle. Your planning system might call it “Walmart Back to School Display.” Your agency might call it “WM BTS Display FY27.” Your ERP knows the associated transaction as PO 450028371. A retail media platform assigns its own campaign number. An invoice eventually arrives with another reference.

Names and system-specific identifiers can change without breaking the connection because the persistent marketing activity ID remains the same. Descriptive fields tell you what something is. A unique ID tells you which exact thing it is. That is a small distinction with enormous implications.

 

## **Why can’t we just use the PO number?**

We can, and PO numbers are useful matching fields. So are Coupon Offer IDs, campaign IDs and other identifiers generated by downstream systems. The problem is that they were created to identify something within a particular process, not to identify a marketing activity throughout its entire lifecycle.

There is also a sequencing problem. Marketing activities are planned before they are committed. A marketer may create a tactic weeks or months before it is sufficiently developed and approved to generate a purchase order. The marketing plan therefore exists before the PO exists.

If the PO number becomes the primary way to connect marketing and financial data, someone must create the PO later, then remember to return to the marketing plan and populate the newly created PO number. Some users will do this consistently. Others will not. Some activities may not require a PO at all. The result is inevitable data gaps.

A persistent marketing activity ID works in the opposite direction. It exists from day one. When the marketer is ready to create a PO, the existing activity ID can be copied into the PO creation form. Now the identity established during planning travels downstream into the financial process. Instead of asking the marketing plan to catch up with Finance after the fact, Finance inherits an identifier that already exists. This leads to an important data architecture principle: the best connective identifier is often the one that exists earliest in the process and persists throughout the rest of it.

 

## **Give your data an address to come home to**

Sending an ID downstream is useful. What happens when data starts coming back is where things get really interesting. Imagine that the activity ID travels into a PO, an agency file, a retail media campaign, a coupon offer or another downstream process. Later, those systems generate financial, execution and performance data.

Actual spend comes back from Finance. Coupon redemption results arrive from the clearinghouse. Media results arrive from an agency or retail media platform. Invoices and deductions appear. Campaign KPIs become available. If those records carry the original activity ID, they can be mapped directly back to the marketing plan that created them.

A unique ID gives downstream data an address to come home to.Without that ID, software can still attempt to determine where the data belongs. It can match on PO number, Coupon Offer ID or combinations of fields such as retailer, brand, campaign name and date. Sometimes that works very well.

But those fields are only useful when they exist and are populated consistently. A missing PO number creates a gap. A differently formatted campaign name creates ambiguity. Dates move. Names change. People abbreviate Walmart three different ways. The more fields you need to interpret in order to determine whether two records represent the same activity, the more exception handling you introduce.

A persistent unique ID turns a reconciliation question from “We think these two records belong together” into “We know these two records belong together.” Multiply that difference across thousands of marketing activities, and suddenly something that looked like database housekeeping becomes an important automation strategy.

 

## **This is how a collection of systems becomes an ecosystem**

Once an activity has a persistent identity, that identity can travel wherever the business needs it to go. It can move into accounting and ERP systems when POs are created, into agency planning and media systems, into TPM platforms, into retail media activation platforms, into coupon and incentive clearinghouse databases, into invoice and deduction processes, and ultimately into data warehouses, BI tools and measurement environments.

Not every connection needs to be a sophisticated real-time integration, either. An ID can travel through an API, an automated data feed, a file export or, when necessary, a simple copy and paste by a user.

That is another reason this approach is practical. You don't have to wait for a multimillion-dollar enterprise integration project before you begin creating continuity. Over time, the process starts to look less like a collection of disconnected transactions and more like a closed loop:

**Plan → Approve → Commit → Execute → Pay → Reconcile → Measure → Learn → Plan again**

The marketing system of record provides the business context. Specialized systems perform their jobs along the way. The persistent ID maintains the thread between them.

Now marketers can begin answering questions that are surprisingly difficult in many organizations today. What did we originally plan? What did we commit? What actually executed? How much have we spent? What hasn't been invoiced yet? What was deducted? What results did the activity generate? How did similar tactics perform in the past? Where should we invest next time? Those questions become easier when the underlying data knows how it fits together.

 

## **Want AI-ready marketing data? Start here.**

This becomes even more important as CPG companies begin thinking seriously about AI. There is a lot of discussion about making enterprise data “AI-ready,” but before an AI agent can provide useful answers about your marketing investments, there is a more fundamental problem to solve: **Can a machine reliably determine which records belong together?**

An AI assistant might eventually be asked, “How much did we invest in Walmart retail media last year, which programs performed best, and what should we consider when building next year's plan?” Answering that question could require planned spend, committed spend, purchase orders, invoices, media performance, sales results and historical campaign information from several different systems.

AI does not eliminate the need for data structure, i makes good data structure more valuable. If the same activity exists under six different names in six different systems and there is no reliable relationship among them, an AI model inherits the same reconciliation problem your analysts have today. Give those records a persistent identity, and you have created a foundation on which much more sophisticated automation and analysis can be built. The humble unique ID turns out to be part of your AI infrastructure.

 

## **How Shopperations approaches the problem**

This philosophy is built into Shopperations. Every marketing activity created in Shopperations automatically receives a unique identifier from the beginning of the planning process.

That ID is visible and reportable. It can be extracted through APIs, included in data feeds and reports, or simply copied by a user into another system. This means it can travel with an activity into whatever downstream processes a company chooses without requiring every system to adopt Shopperations' nomenclature.

When data comes back, Shopperations can use that UID to map the information directly to the existing marketing plan. Other matching fields, such as PO numbers and Coupon Offer IDs, can also be used when appropriate, but the UID provides the most reliable connection because it exists for every activity from the moment that activity is created.

The result is continuity between planning and everything that follows. This is ultimately what a marketing system of record should do. It shouldn't try to replace every specialized platform your organization uses. It should establish the company's marketing data model, provide a consistent version of the truth, and give the rest of the ecosystem something reliable to connect to. That idea of maintaining one version of the truth is already central to how Shopperations describes the value of its planning and collaboration platform.

 

## **Own the identity, not every system**

Marketers will probably never have one technology platform that does everything, nor should they. Finance, agencies, retailers, media platforms, clearinghouses and marketing teams have different jobs to do and different technology requirements.

The opportunity is not to force every system into the same language. It is to establish your company's language for marketing first, then give every activity a persistent identity that can survive wherever that activity travels.

Own your data model. Own your nomenclature. Establish the identity at the beginning of the process. Then let your specialized systems do what they do best. Once every system can reliably answer the deceptively simple question, “Which marketing activity is this?”, a surprising number of harder problems become much easier to solve.
