Excel, YourValidator, or Enterprise-MMM software?
A Comparison of the Three Approaches to Marketing Budget Planning
Decision-Making Guide · MMM Strategy Software for SMEs, Agencies, and Consultants
Three Ways to Plan Marketing Budgets—and the Answer to Which One Best Fits Your Data, Budget, and Specific Needs.
Level 1
Excel / spreadsheet
Manual budget and channel planning based on your own formulas and assumptions.
For SMBs with simple, static planning needs.
Level 2 · upstream layer
YourValidator
Structured, deterministic strategy and budget validation without your own data history — benchmark- and input-based, with optional AI help for filling in the fields (BYOK).
For SMBs and agencies that need decision-ready budget and channel hypotheses fast.
Level 3
Enterprise MMM
Fully integrated, causal MMM using your own company data, an analytics team and ongoing model refreshes.
From roughly $3–5M media spend, $20M+ revenue and 18–24 months of clean data history.
Important contextYourValidator is an upstream planning and validation layer, not a fully integrated causal MMM built on company data. Its strength is the immediate structuring of budget, channel and scenario hypotheses — not rigorous, historical causal proof. The calculation logic is deterministic and transparent; the optional AI function (with your own API key) helps fill in the input fields, it does not compute the results.
01
A quick reality check
Answer these questions Yes or No before choosing a method.
- Do harmonised marketing, sales and financial data exist — clean and weekly — for at least 18–24 months?
- Do we need rigorous causal proof (incremental effects) based on our own company data?
- Is MMM firmly embedded in P&L, sales, pricing and revenue steering?
- Is an analytics team available for continuous model refreshes?
- Is the MMM budget in the enterprise-SaaS range (typically ~$30,000–80,000/year for mid-market, sometimes more)?
- Is annual media spend in the several-million-euro range?

Head-to-head: YourValidator vs. classic Excel planning
| Criterion | YourValidator (browser tool) | Classic Excel planning |
|---|---|---|
| Accuracy & methodology | Deterministic, parameterisable model logic on a benchmark basis; seasonality, saturation and halo effects structured; reproducible and transparent. | Depends entirely on the assumptions entered; error-prone through manual chaining; no standardised modelling. |
| Type of output | Structured budget and channel hypotheses with visualised forecasts; planning and validation layer. | Free but unstructured assumption planning; no standardised method model. |
| Ease of use | Ready to use immediately; optional AI help can pre-fill channels and assumptions. | Familiar, but heavy manual setup; formulas, pivots and charts built by hand. |
| Data-integration effort | Low – works even without your own data history, benchmark- and input-based. | Medium to high – data collected, cleaned and forced into a table structure by hand. |
| Scenario planning | Fast simulation; budget, seasonality and saturation parameters changeable in seconds. | Possible, but every change means manual adjustment and recalculation. |
| Forecasting | Instant, visualised forecasts; optional AI support (BYOK) when filling in fields — the calculation itself stays deterministic. | Manual; forecasts built by formula or add-in yourself. |
| Transparency | Traceable parameters and visualised outputs. | Fully transparent, but only as good as your own modelling. |
| Data protection | Runs entirely in the browser; no data held on external servers, no IT integration needed. | Local, but no structured collaboration; versions traded by file/email. |
| Cost | Free version with full functionality; commercial use via Pro licence from $170/year. | Seemingly free – hidden costs through time, errors and lack of updates. |
| Scalability | Browser-based, channels freely extendable; embed/white-label option for agencies. | Limited by table structure and manual upkeep. |
| Team capability | Shareable scenarios via backup file; suited to the agency/client conversation. | Version chaos, email attachments, no real collaboration. |
The objective limitNeither Excel nor YourValidator replaces a fully causal MMM on your own data history. Both provide decision inputs and hypotheses, not rigorous historical causal proof.
03
How YourValidator closes the gap
YourValidator positions itself as a bridge between manual Excel strategy and enterprise MMM software — and deliberately starts earlier, in the phase where you plan and pitch, before you have enough first-party data for a data-hungry MMM at all.
- Immediate structure instead of a blank sheet. Rather than starting from an empty Excel file, YourValidator gives you a methodically sound structure for budget, channel and scenario hypotheses right away.
- Validation before the big investment. The business case for a costly MMM platform or a consulting engagement can be modelled before budget is committed.
- Planning and validation layer. Not a replacement for a deeply integrated MMM programme, but an upstream layer for strategy and budget validation.
- Accessibility. SMBs and agencies gain access to methods once reserved for enterprise software or consulting engagements — from a budget of $0 (free version).
04
When YourValidator is the right choice
Applies when at least four of the following are true.
- You need a structured budget and channel hypothesis within hours or days – not historical causal proof.
- Historical data isn't sufficiently harmonised yet, or isn't available weekly across 18–24 months.
- The team wants to discuss seasonality, saturation, halo effects and budget alternatives transparently.
- The business case for an expensive MMM platform or a consulting engagement isn't validated yet.
- Marketing plans largely on its own; sales and finance supply framework assumptions rather than daily integrated data.
- A lean, browser-based solution is preferred over a data-intensive managed-service model.
- You want to start without data-integration effort and without a long implementation.
- The entry point should be $0 (free); commercial use is covered by a Pro licence from $170/year.
05
When Excel is no longer enough
If any of these apply, moving from Excel to YourValidator makes economic and methodological sense.
- Scenarios must be compared in minutes rather than hours.
- Different stakeholders (marketing, agency, client) should work from the same basis.
- Forecasts must be repeatable, traceable and updatable.
- Saturation, halo and seasonal effects should be modelled cleanly.
- A visual, decision-ready presentation for management or investors is needed.
06
When enterprise MMM becomes necessary
- Rigorous, historical causal proof (incremental effects per channel) on your own company data is required.
- Annual media spend reaches several million euros (typical threshold ~$3–5M spend or $20M+ revenue).
- At least 18–24 months of clean weekly data across 3–5+ channels exist.
- MMM is to be firmly embedded in P&L, sales, pricing and revenue steering.
- A dedicated analytics team runs continuous model refreshes.
Price corridor for orientationCommercial SaaS MMM platforms in the mid-market typically run $30,000–80,000/year (simple, digital); with multi-geo or offline channels this rises to $80,000–200,000+/year. Open-source alternatives (Google Meridian, Meta Robyn, PyMC-Marketing) are licence-free but create substantial internal analysis and data effort and require a statistically capable team. Google's earlier LightweightMMM has been unsupported since 2025; its successor is Meridian.

Cost-benefit — start at $0
| Aspect | Excel (manual) | YourValidator |
|---|---|---|
| Licence cost | $0 | $0 (free, full functionality) / Pro licence from $170/year |
| Time to first result | Hours to days | Minutes |
| Error & rework risk | High (manual formulas) | Lower (deterministic, standardised model logic) |
| Decision-readiness of outputs | Medium – depends on the modeller | Higher – visualised, methodically structured forecasts |
| Recurring upkeep | High – manually each quarter | Low – runs in the browser, no formula sheets to maintain |
| Fit as pitch/investor material | Limited | High – professional visualisations |
On the licence modelThe free version offers full functionality for risk-free testing. The Pro licences don't unlock additional features but the commercial usage right for your own business decisions, client reports and commercial pitches: Single $170, Team $350, Embed/Agency $690 per year.
Economic bottom line: The planning time saved on a single workshop typically exceeds the annual cost of the Pro licence. The free version also allows a complete, risk-free evaluation.
08
Recommendation for SMBs
Summary
YourValidator closes the gap between manual Excel strategy and enterprise software by making structured, deterministically calculated budget and channel hypotheses accessible — without data-integration effort and from a budget of $0. It's the right step when SMBs and agencies want to reach decision-ready hypotheses faster, without immediately investing in expensive platforms or consulting engagements.
Where rigorous historical causal proof on your own data and in P&L steering is required, the enterprise-MMM level remains the methodologically apt approach.
