CODITECT Financial Model — Improvement Recommendations

Executive Summary​

Analysis of the current financial model reveals 23 enhancement opportunities across 6 categories. Implementation of high-priority improvements could increase model accuracy by 30-40% and provide 5-10 additional decision-support scenarios.

CATEGORY 1: MODEL STRUCTURE​

1.1 Add Scenario Switching [HIGH PRIORITY]​

Current State: Single fixed scenario with manual edits required
Recommendation: Add scenario selector with pre-configured cases

Implementation:

Dashboard!A1: Scenario dropdown
- Base Case (current)
- Conservative (50% growth rates)
- Aggressive (150% growth rates)
- Bootstrap ($0 funding)
- Extended Runway (50% OpEx)

Value: Instant scenario comparison for investor meetings

1.2 Separate Inputs from Calculations [HIGH PRIORITY]​

Current State: Assumptions scattered across multiple sheets
Recommendation: Create dedicated "Inputs" sheet with all editable values

Implementation:

  • Move all blue (hardcoded) cells to single Inputs sheet
  • Replace original cells with references: =Inputs!B5
  • Group inputs by category with clear labels

Value: Single location for all sensitivity analysis, reduced error risk

1.3 Add Data Validation [MEDIUM PRIORITY]​

Current State: No input constraints
Recommendation: Add validation rules to prevent illogical inputs

Examples:

  • Growth rates: 0% - 500%
  • Churn rates: 0% - 100%
  • Customer mix: Must sum to 100%
  • Prices: > $0
  • Dates: Valid date format

Value: Prevent model-breaking errors

1.4 Add Named Ranges [MEDIUM PRIORITY]​

Current State: Cell references (B5, C10)
Recommendation: Use descriptive named ranges

Examples:

  • Individual_Price instead of Assumptions!C2
  • M1_Growth_Rate instead of Assumptions!C9
  • Total_Funding instead of Dashboard!B9

Value: Self-documenting formulas, easier auditing

CATEGORY 2: REVENUE MODEL ENHANCEMENTS​

2.1 Add Expansion Revenue [HIGH PRIORITY]​

Current State: Revenue = New customers only
Recommendation: Model seat expansion within accounts

Implementation:

Expansion MRR = Existing_Customers × Expansion_Rate × Avg_Seat_Addition × Price

Suggested Assumptions:

  • Monthly expansion rate: 3-5% of Team/Enterprise accounts
  • Average seat addition: 2-3 seats

Value: More accurate revenue forecasting, NRR calculation

2.2 Model Pricing Changes [MEDIUM PRIORITY]​

Current State: Fixed pricing throughout projection
Recommendation: Allow for planned price increases

Implementation:

  • Add "Price Effective Date" columns
  • Model 5-10% annual price increases
  • Grandfather existing customers option

Value: Realistic long-term revenue projection

2.3 Add Annual Contract Modeling [MEDIUM PRIORITY]​

Current State: Annual discount mentioned but not fully modeled
Recommendation: Separate annual vs. monthly customer cohorts

Implementation:

Annual_Customers = Total × Annual_Percentage
Annual_Revenue = Annual_Customers × Price × 12 × (1 - Discount)
Monthly_Revenue = Monthly_Customers × Price

Value: Better cash flow timing, churn dynamics

2.4 Add Downgrades [LOW PRIORITY]​

Current State: Customers only churn or stay
Recommendation: Model Enterprise → Team → Individual downgrades

Implementation:

  • Monthly downgrade rates by tier
  • Revenue impact calculation
  • Separate from churn in reporting

Value: More accurate revenue retention metrics

CATEGORY 3: EXPENSE MODEL ENHANCEMENTS​

3.1 Dynamic Headcount Planning [HIGH PRIORITY]​

Current State: Fixed hire waves (Month 5, 17, 29)
Recommendation: Revenue-triggered hiring model

Implementation:

Required_Engineers = Revenue / Engineer_Productivity_Target
Hire_Trigger = IF(Current < Required AND Revenue > Threshold)

Suggested Ratios:

  • Engineer per $500K ARR (pre-scale)
  • Engineer per $1M ARR (post-scale)

Value: Headcount aligns with business growth

3.2 Department-Level Expenses [MEDIUM PRIORITY]​

Current State: Single "Salaries" line item
Recommendation: Break down by department

Implementation:

Engineering: X headcount × Avg Eng Salary × Benefits
Sales: Y headcount × Base + Commission structure
Marketing: Z headcount + Programs budget
G&A: Finance, HR, Legal headcount

Value: Better resource allocation planning

3.3 Variable Commission Structure [MEDIUM PRIORITY]​

Current State: No sales compensation modeling
Recommendation: Add commission/quota model

Implementation:

AE Compensation = Base + (New_ARR × Commission_Rate)
Commission_Rate = 10% of Year 1 ACV
OTE = Base × 2 (50/50 split)

Value: Accurate sales cost modeling at scale

3.4 Infrastructure Scaling Curves [LOW PRIORITY]​

Current State: Linear 5% of revenue
Recommendation: Step-function or log curve

Implementation:

Infra_Cost = Base_Cost + (Revenue × Variable_Rate) + Step_Increases
Step_Increases at: $1M, $5M, $20M ARR thresholds

Value: Reflects real infrastructure economies of scale

CATEGORY 4: METRICS & ANALYTICS​

4.1 Add Cohort Analysis [HIGH PRIORITY]​

Current State: Aggregate customer counts only
Recommendation: Track customers by acquisition month

Implementation:

  • New sheet: "Cohorts"
  • Rows: Acquisition month
  • Columns: Months since acquisition
  • Values: Remaining customers, Revenue

Recommendation: Dynamic blended metrics over time

Metrics to Add:

  • Blended CAC (weighted by new customer mix)
  • Blended LTV (weighted by customer mix)
  • LTV/CAC trend over time
  • Payback period trend
  • Magic Number (Net New ARR / S&M Spend)

Value: Track unit economics health over time

4.3 Add SaaS Benchmarks [MEDIUM PRIORITY]​

Current State: No external comparison
Recommendation: Add industry benchmark ranges

Examples:

MetricYour ModelBenchmark
Gross Margin85%70-85% ✓
LTV/CAC4.5x>3x ✓
Payback<1mo<12mo ✓
Churn33%<5% ✗

Value: Quick health check against standards

4.4 Add Quick Ratio [LOW PRIORITY]​

Current State: Not calculated
Recommendation: Add SaaS Quick Ratio

Formula:

Quick_Ratio = (New_MRR + Expansion_MRR) / (Churned_MRR + Contraction_MRR)
Target: > 4.0

Value: Growth efficiency metric

CATEGORY 5: CASH FLOW REFINEMENTS​

5.1 Add Working Capital [HIGH PRIORITY]​

Current State: Cash = Revenue - Expenses
Recommendation: Model AR/AP timing

Implementation:

Days_Sales_Outstanding = 30-60 days
Cash_Received = Revenue[t - DSO_days]
Days_Payable = 30 days
Cash_Paid = Expenses[t - DPO_days]

Value: Accurate cash position, especially for enterprise

5.2 Model Deferred Revenue [MEDIUM PRIORITY]​

Current State: Not tracked
Recommendation: Balance sheet impact of annual contracts

Implementation:

Deferred_Revenue = Annual_Contracts × Remaining_Months / 12
