b2b-revenue-forecasting 0.3.4

A Python framework for hierarchical B2B sales quota cascading and pipeline reconciliation.

B2B Revenue Forecasting (b2b_revenue_forecasting)

An open-source Python framework designed mathematically for Enterprise RevOps and Data Strategy teams.

Unlike traditional bottom-up time-series libraries (which are strictly built for B2C retail/inventory forecasting and rely on mathematical averages), this package is explicitly architected to handle the realities of B2B enterprise sales: Hierarchical Quotas, Managerial Cascading, Pipeline Health Analysis, and "Sandbagging" Biases.

🚀 Features

Module	Purpose
SalesHierarchy	Build flexible org charts as DAGs from flat CRM data — supports 3-level startups to 10-level enterprises
QuotaCascader	Distribute macro-targets top-down using rolling N-quarter capacity models with configurable managerial hedges
MetricSpec	Declare which historical metrics (NetNewACV, CloudSeats, DC seats, LTM expansion, …) drive cascading, in what direction (proportional or inverse), and at what weight — with auto-suggested weights from correlation analysis
CommitReconciler	Detect sandbagging and "happy ears" bias via historical Bias Quotients, then auto-correct forecasts
PipelineAdjuster	Diagnose pipeline health with per-region thresholds and redistribute IC quotas using zero-sum logic

What's New in v0.3.x

• Multi-metric cascading via the new MetricSpec API — blend historical NetNewACV with any number of secondary signals (cloud seats, on-prem seats, LTM expansion spend, customer-sat scores, certification flags, anything else the analyst tracks), each marked as proportional or inverse, with per-metric weights and lookbacks
• Direction is always a user input. Domain knowledge ("more cloud seats means more ACV") trumps statistical sign. The package surfaces correlations and warns on mismatch but never overrides the analyst's call
• MetricSpec.suggest_weights(...) suggests weights (magnitude of correlation) for user-declared directions. For exploratory use, MetricSpec.suggest_directions_and_weights(...) infers both
• Normalized-weights view — MetricSpec.normalized_weights(specs) shows the post-normalization share each metric actually contributes; auto-printed before every multi-metric cascade and accessible via cascader.weights_report
• Brand-new IC handling — either-or: flag brand-new ICs in the same CSV the analyst already uploads (brand_new_col='Is_Brand_New' on SalesHierarchy.from_dataframe, then new_ic_attr='_is_brand_new' on cascade_quota), OR pick a rule (new_ic_rule='all_metrics_zero' / 'primary_metric_zero'). Passing both raises ValueError
• Any metric name, any numeric type — including booleans (Has_Active_Cert: True/False). Boolean / 0-1 sparse metrics are auto-detected and excluded from zero-imputation so False isn't mistaken for missing data
• PipelineAdjuster accepts multiple pipeline columns — pipeline_attr=['Open_Pipeline', 'Late_Stage_Commit', 'Best_Case_Adds'] sums them per IC into a combined dollar amount for the coverage ratio
• CSV / SQL / dashboard exports — every output converts to a DataFrame via cascader.quotas_to_dataframe(...), cascader.quotas_diff_to_dataframe(...), or reconciler.reconcile_all(...). From there .to_csv(), .to_sql(), or cascader.to_html_dashboard(...) writes wherever you need
• Hedge audit columns — pass unhedged_quotas= to quotas_to_dataframe for unhedged_quota, hedge_buffer, and overassignment_pct columns showing exactly how much of each quota is hedge buffer
• Fully backward compatible — cascade_quota(...) without metrics= behaves exactly as in v0.2.x

What's New in v0.2.0

• PipelineAdjuster: Post-cascade pipeline health analyzer with diagnose() and adjust() modes
• Flexible quarter support: QuotaCascader now auto-discovers any number of _Attainment columns (4, 8, 12 quarters)
• New IC handling: Partial-history imputation and equal-share allocation for brand-new hires
• CRO overrides: Lock specific IC quotas via new_ic_overrides to bypass the algorithm
• Per-node hedging: Apply different hedge multipliers to different regions/managers
• GitHub Actions CI/CD: Automated testing on Python 3.9–3.12

💻 Quickstart

1. Build the Org Hierarchy

import pandas as pd
from b2b_revenue_forecasting.hierarchy import SalesHierarchy

# ⚠️ Use keep_default_na=False if your data has 'NA' as a region name
df = pd.read_csv('your_crm_data.csv', keep_default_na=False)

# Works with any depth: 3 levels or 10 levels
hierarchy = SalesHierarchy()
hierarchy.from_dataframe(
    df, 
    path_cols=['Global', 'Region', 'RVP', 'Director', 'Manager', 'IC'], 
    metrics_cols=['Q1_Attainment', 'Q2_Attainment', 'Q3_Attainment', 'Q4_Attainment',
                  'Current_Pipeline']
)

print(f"Nodes: {len(hierarchy.graph.nodes)}")
print(f"ICs:   {len(hierarchy.get_leaves('Global_Corp'))}")

2. Cascade Quotas Top-Down

from b2b_revenue_forecasting.quota_cascader import QuotaCascader

cascader = QuotaCascader(hierarchy)

# Basic: distribute $100M evenly by historical capacity
quotas = cascader.cascade_quota('Global_Corp', 100_000_000.0)

# With 5% hedge at every management level (compounds: 1.05^5 ≈ 27.6% overassignment)
quotas = cascader.cascade_quota('Global_Corp', 100_000_000.0, hedge_multiplier=1.05)

# Per-node hedge: NA gets aggressive 10%, others standard 5%
quotas = cascader.cascade_quota('Global_Corp', 100_000_000.0, hedge_multiplier={
    'Global_Corp': 1.05, 'NA': 1.10, 'EMEA': 1.05, 'APAC': 1.05
})

# CRO override: strategic hire gets exactly $500K regardless of history
quotas = cascader.cascade_quota('Global_Corp', 100_000_000.0,
    hedge_multiplier=1.05,
    new_ic_overrides={'IC_Strategic_Hire': 500_000.0}
)

3. Multi-Metric Cascading (v0.3+)

For real B2B planning, the metric you're cascading (e.g., NetNewACV) is rarely the only signal that should drive its allocation. Cloud-seat counts predict more new ACV; on-prem (DC) seat counts predict less; high LTM expansion spend means the account is already saturated. The MetricSpec API lets you mix any number of these into a single cascade.

Direction is always your call. You declare whether each metric is proportional (more → more quota) or inverse (more → less quota) up front. The package surfaces correlations and warns when the data sign disagrees, but never overrides your domain knowledge.

from b2b_revenue_forecasting import MetricSpec

# Declare each metric's role — direction is required, weight is your knob
metrics = [
    MetricSpec('NetNewACV',     direction='proportional', weight=1.0, lookback=4),
    MetricSpec('CloudSeats',    direction='proportional', weight=0.5, lookback=4),
    MetricSpec('DCSeats',       direction='inverse',      weight=0.4, lookback=4),
    MetricSpec('ExpansionSpent',direction='inverse',      weight=0.7,
               columns=['LTM_ExpansionSpent']),  # single LTM column
]

quotas = cascader.cascade_quota(
    'Global_Corp', 100_000_000.0,
    hedge_multiplier=1.05,
    metrics=metrics,
)

Any metric name, any data type works. Customer_Sat_Score, MQLs_Sourced_via_Outbound, Has_Active_Cert (boolean), Renewals_Caught_Up (0/1 counter) — anything numeric, with any column name. Boolean and 0/1 sparse metrics are auto-detected and excluded from zero-imputation so False isn't treated as a missing value.

How the blend works. At every level, each child gets a share of the parent's quota equal to a weighted sum of its per-metric shares-of-siblings. Proportional metrics use raw shares; inverse metrics flip via reciprocal-then-normalize. The final per-child share is Σ_m (weight_m × share_m(child)), which sums to 1 across siblings.

Don't know the weights? Pass direction= on each candidate, let suggest_weights() propose magnitudes via Pearson correlation:

suggestions, report = MetricSpec.suggest_weights(
    df,
    target_column='NetNewACV_4Q_sum',
    candidate_metrics=[
        {'name': 'CloudSeats',     'column': 'CloudSeats_4Q_sum',
         'direction': 'proportional', 'lookback': 4},
        {'name': 'DCSeats',        'column': 'DCSeats_4Q_sum',
         'direction': 'inverse',      'lookback': 4},
        {'name': 'ExpansionSpent', 'column': 'LTM_ExpansionSpent',
         'columns': ['LTM_ExpansionSpent'],
         'direction': 'inverse',      'lookback': 1},
    ],
)
# report['CloudSeats']['weight'] == 0.62, ['rationale'] explains why,
# ['direction_matches_data'] tells you if your call agrees with the sign

quotas = cascader.cascade_quota('Global_Corp', 100_000_000.0, metrics=suggestions)

For pure exploration (you don't yet have a domain opinion), use MetricSpec.suggest_directions_and_weights(...) — it infers both from data. This is a sanity-check helper, not a production-planning API.

Brand-new ICs — either-or, your choice of where they're listed. The cleanest option keeps everything in the same CSV the analyst already uploads:

# CSV has a column Is_Brand_New with True / 1 / "yes" for each new hire
hierarchy = SalesHierarchy()
hierarchy.from_dataframe(
    df, path_cols=[...], metrics_cols=[...],
    brand_new_col='Is_Brand_New',     # ingested as node attribute _is_brand_new
)

quotas = cascader.cascade_quota(
    'Global_Corp', 100_000_000.0,
    metrics=metrics,
    new_ic_attr='_is_brand_new',       # read the flag from the CSV
)

Or, if you don't want a separate column, pick an auto-detection rule:

quotas = cascader.cascade_quota(
    'Global_Corp', 100_000_000.0,
    metrics=metrics,
    new_ic_rule='all_metrics_zero',    # or 'primary_metric_zero'
)

You pick one or the other — passing both an explicit identifier (new_ic_attr or new_ic_ids) AND new_ic_rule in the same call raises ValueError, because the two would silently disagree.

Brand-new ICs get an equal-share carve-out of the team target before the remainder is split proportionally — just like the single-metric path.

4. Detect & Fix Forecasting Bias

from b2b_revenue_forecasting.commit_reconciler import CommitReconciler

historical = pd.DataFrame({
    'Manager_ID':              ['Mgr_A', 'Mgr_A', 'Mgr_B', 'Mgr_B'],
    'Historical_Commit':       [200_000,  250_000, 300_000,  350_000],
    'Historical_Actual_Closed': [300_000,  375_000, 270_000,  280_000],
})

reconciler = CommitReconciler(historical)

# Mgr_A is a sandbagger (bias = 1.5x) — commit inflated automatically
adjusted = reconciler.reconcile_forecast('Mgr_A', current_commit=100_000)
# → $150,000

# Blend with ML baseline (50/50 average)
blended = reconciler.reconcile_forecast('Mgr_A', 100_000, machine_forecast=120_000)
# → $135,000

5. Export to CSV, SQL, or an Interactive Dashboard

Every output is a pandas DataFrame, so the same code writes anywhere:

# CSV — analyst-ready, one row per node at every level
cascaded_df = cascader.quotas_to_dataframe(quotas, level_names=taxonomy)
cascaded_df.to_csv('cascaded_quotas.csv', index=False)

# CSV with hedge audit — also include the unhedged baseline
quotas_unhedged = cascader.cascade_quota(
    'Global_Corp', 100_000_000.0, hedge_multiplier=1.0,
    metrics=cascade_metrics, verbose=False,
)
cascader.quotas_to_dataframe(
    quotas, level_names=taxonomy, unhedged_quotas=quotas_unhedged,
).to_csv('cascaded_quotas_with_audit.csv', index=False)
# → adds unhedged_quota, hedge_buffer, overassignment_pct columns

# SQL — same DataFrames, any SQLAlchemy-compatible database
import sqlite3
with sqlite3.connect('cascade.db') as conn:
    cascaded_df.to_sql('cascaded_quotas', conn, if_exists='replace', index=False)
    cascader.weights_report.to_sql('normalized_weights', conn,
                                    if_exists='replace', index=False)
# Postgres / Snowflake / BigQuery: swap conn for a SQLAlchemy engine

# Interactive HTML dashboard — Chart.js, self-contained, shareable
cascader.to_html_dashboard(
    quotas, output_path='cascade_dashboard.html',
    title='Q1 Cascade — $100M Plan',
    unhedged_quotas=quotas_unhedged,
    adjusted_quotas=adjusted, diagnosis=diagnosis,
)

6. Pipeline Health Diagnosis & Redistribution

from b2b_revenue_forecasting.pipeline_adjuster import PipelineAdjuster

# Single pipeline column (backward compat)
adjuster = PipelineAdjuster(hierarchy, quotas, pipeline_attr='Current_Pipeline')

# Or sum multiple dollar-denominated pipeline columns from the same CSV
adjuster = PipelineAdjuster(hierarchy, quotas, pipeline_attr=[
    'Open_Pipeline', 'Late_Stage_Commit', 'Best_Case_Adds',
])

# Configure per-region coverage thresholds (ICs inherit from ancestors)
thresholds = {
    'NA':       {'healthy': 1.5, 'at_risk': 0.8},
    'EMEA':     {'healthy': 2.5, 'at_risk': 1.2},
    'APAC':     {'healthy': 3.0, 'at_risk': 1.5},
    '_default': {'healthy': 2.0, 'at_risk': 1.0}
}

# Diagnose — returns a DataFrame with risk status for every node
diagnosis = adjuster.diagnose(thresholds)
print(diagnosis.groupby('Risk_Status')['Node'].count())

# Flag-only mode — returns original quotas unchanged (for pre-approval review)
flagged = adjuster.adjust(mode='flag_only', coverage_thresholds=thresholds)

# Redistribute mode — zero-sum IC adjustment within each manager's team
adjusted = adjuster.adjust(
    mode='redistribute',
    coverage_thresholds=thresholds,
    max_adjustment_pct=0.20,                          # ±20% cap per IC
    locked_nodes={'IC_Protected': 500_000.0}           # CRO-locked ICs excluded
)
# ✅ Manager totals preserved | ✅ Donors give, receivers get | ✅ 20% cap enforced

🧠 Key Concepts

Managerial Hedge (Overassignment Buffer)

A multiplier applied at each management level to create mathematical safety. A 5% hedge across 5 layers compounds to ~27.6% total overassignment (1.05⁵), ensuring the enterprise hits its number even if some ICs miss.

Bias Quotient

Bias Quotient = Σ(Actual Closed) / Σ(Committed)

• > 1.0 = Sandbagger (closes more than committed → inflate their forecast)
• = 1.0 = Neutral
• < 1.0 = Happy Ears (over-promises → deflate their forecast)

Pipeline Coverage Ratio

Coverage = Current Pipeline / Cascaded Quota

Coverage	Status	Action
≥ healthy threshold	🟢 Healthy	May receive quota
≥ at_risk threshold	🟡 Moderate	No action
≥ 1.0	🟠 At Risk	May donate quota
< 1.0	🔴 Critical	Urgent — pipeline below target (May donate quota)

New IC Handling

Scenario	Behavior
Full history	Proportional by total capacity
Partial history (e.g., 1 of 4 quarters)	Zero quarters imputed with own non-zero average
Brand new (all zeros)	Equal share of team target
CRO override	Fixed amount, excluded from pool
