Pitch Book Version Control: Stop the FINAL_final Deck and Model Spiral

If the filename says FINAL_final_v7, you already know the deck has been turned so many times that quality drift is inevitable.  

Maybe someone pasted a chart from a different pitch book three hours ago, or bullet punctuation is doing its own thing. Somewhere in the Excel model, a hardcoded number is destroying what you thought was a clean formula. 

None of this happens because of a lack of care. It happens because every edit introduces tiny inconsistencies, and after enough turns, drift becomes rework and more rework. 

This is where Macabacus’ Deck Check and Model Check come in. These tools scan decks and models for errors and inconsistencies and allow users to fix them with just a few clicks. 

  • Deck Check scans PowerPoint presentations for formatting, branding, and consistency errors 
  • Model Check audits Excel workbooks with 50+ checks to flag modeling integrity problems like formula errors, hardcoded values, and broken links.

Why Pitch Books Get Messy 

Manual proofing fails for one reason: scale. If you’re working on pitch books, CIMs, or client decks, you’re usually dealing with: 

  • Dozens of slides 
  • Multiple contributors 
  • Multiple rounds of edits 
  • Multiple formatting “styles” sneaking in  

Deck Check is built to catch problems across formatting, branding, and layout, and it can propose fixes to speed correction. By connecting to your shared libraries and customized brand styles (colors, fonts, and other standards), it helps ensure the deck is truly on brand.” It’s Reformat View inventories fonts, fills, borders, paragraph styles, and more, so you can identify inconsistencies and replace undesired formatting across the presentation quickly.

Deck QC Isn’t Enough If the Model Is Drifting 

Here’s the other half of the “final version” spiral: You can have a clean deck built on a questionable model. Model issues are harder to spot, and the cost of being wrong is higher than the cost of a misaligned textbox. 

If you’ve ever had to do a last-minute financial model audit, these probably look familiar: 

  • “Can we confirm there are no broken links?” 
  • “Are there any hardcoded values in formulas?” 
  • “Does this sheet have inconsistent formulas across the range?” 
  • “Why is the model pulling from an external file that no one can find?” 

You don’t need a perfect audit. You need to catch the handful of issues that turn into bad outputs, rework, or awkward client follow-ups. A quick model check during the turn gives you confidence the numbers behind the deck still hold up before anything goes out the door. 

How To Audit an Excel Model Without Spending Your Night Tracing Cells 

Model Check is built for auditing complex Excel models quickly, using 50+ checks, including: 

  • Audit for formula errors 
  • Flag hardcoded values 
  • Catch broken links 
  • Review complex workbooks in seconds, not hours 

And importantly, you can tune it to your tolerance for risk. Built by financial analysts for financial analysts, Model Check is designed around how bankers and investors actually audit models, so severity settings align with real review priorities. Model Check lets you set severity levels for checks (high/medium/low).  

Why This Matters for “Find Hardcoded Values in Excel Model” 

Hardcodes aren’t always wrong, but they’re almost always suspicious. When you’re doing Excel model checks, you’re usually trying to answer: 

  • Did someone override a link by pasting a number? 
  • Did a formula get replaced with a value during a quick fix? 
  • Is the model’s logic consistent across the section?  

Model Check is explicitly built to flag hardcoded values as part of its auditing pass. Instead of checking cell by cell, you can run one check and get a clear list of where hardcodes appear, so you can validate the logic quickly and move on. 

The Combined Workflow: Keep Decks Clean and Models Credible, Every Turn 

Here’s how you stop the “final” spiral: 

1) Treat the deck and model as one deliverable 

If you update numbers, you update the following as part of the turn: 

  • The model logic (and audit it) 
  • The deck outputs (refresh linked Excel content and proof the slides)

2) Run quick checks early, not hero checks late 

Instead of: 

  • 90 minutes of frantic cleanup at the end  

You do: 

  • 10 minutes mid-turn 
  • 10 minutes pre-send

3) Let automation catch what humans miss 

Deck Check helps prevent formatting drift from turning into “pls fix” markups by scanning for presentation issues and inconsistencies.  

Model Check helps make sure your analysis is accurate and client-ready by running 50+ auditing checks to surface model integrity issues.  

PowerPoint Version Control Should Be Baked into the Process 

The FINAL_final spiral doesn’t have to derail your projects or cause more late nights. You just need: 

  • A simple, repeatable turn workflow 
  • Short QC checkpoints 
  • One-click tools that scale with the reality of banking timelines  

Run Deck Check to keep PowerPoint formatting consistent and prevent PowerPoint formatting drift from derailing your deck. Run Model Check to catch formula errors, hardcoded values, and broken links before they make it into your output.
