How should a 2027 sales and marketing team run joint forecasting?
Direct Answer
A 2027 sales and marketing team runs joint forecasting by maintaining a single shared funnel model that connects marketing pipeline (MQL volume) → sales pipeline (SQL and opportunity) → revenue (closed-won), reviewed weekly by CRO + CMO with conversion rates and cycle-time assumptions explicit, and reforecast monthly with documented variance to plan.
Pavilion's 2026 Joint Forecasting Benchmark of 287 GTM teams found that companies running joint forecasts hit revenue plan within 5 percent 78 percent of quarters versus 52 percent for companies running separate marketing and sales forecasts. The 2027 best practice: marketing forecasts MQL volume and quality; sales forecasts pipeline-to-revenue conversion; RevOps maintains the integrated model; the CRO and CMO co-own the forecast number to the CEO and board.
Without joint forecasting, the inevitable misalignment hits at quarter-end with finger-pointing — "marketing missed pipeline" vs "sales missed conversion."
1. The Joint Funnel Model
1.1 The 5-stage forecast
The integrated forecast covers 5 stages:
- MQL volume (marketing forecast).
- MQL-to-SQL conversion rate (joint marketing + BDR).
- SQL-to-pipeline conversion rate (sales forecast).
- Pipeline-to-closed-won conversion rate (sales forecast).
- Average deal size (sales forecast with marketing-segmented contribution).
Each stage has a target, a current rate, and a forecasted rate for the next quarter.
1.2 The math
For a target of US$15M in net-new ARR per quarter:
- Average deal size: US$60K ACV.
- Required closed-won deals: 250 per quarter.
- Pipeline-to-closed-won conversion: 22 percent.
- Required pipeline created: 1,140 opportunities per quarter.
- SQL-to-pipeline conversion: 65 percent.
- Required SQLs: 1,750 per quarter.
- MQL-to-SQL conversion: 30 percent.
- Required MQLs: 5,840 per quarter.
If marketing forecasts 5,000 MQLs, the gap (840 MQLs) requires a plan: outbound BDR can fill 50 percent of the gap; marketing increases campaign investment to fill the rest; or sales adjusts conversion expectations.
1.3 The conversion-rate transparency
Each conversion rate has historical context, current trend, and forecast assumption:
- Historical: trailing 4-quarter average.
- Current: trailing 13-week.
- Forecast assumption: what we believe will happen next quarter (with rationale).
Pavilion's 2026 forecast accuracy data shows that explicit conversion-rate assumptions correlate with 18-percent better forecast accuracy than implicit "we assume rates hold" approaches.
2. The Weekly Cadence
2.1 The 60-minute Monday joint review
CRO + CMO + VP RevOps + heads of demand gen and sales development:
- 10 min — MQL volume vs target by segment and channel.
- 10 min — SQL conversion and pipeline coverage status.
- 10 min — pipeline-to-revenue conversion (forecast call review).
- 15 min — gap analysis and corrective actions.
- 15 min — alignment on next-week priorities.
2.2 The shared dashboard
A single shared dashboard in Clari, BoostUp, Gong Forecast, Tableau, or Looker. Both CRO and CMO consume the same view. No competing dashboards.
The dashboard shows:
- Each funnel stage with target vs actual vs forecast.
- Conversion rates with confidence intervals.
- Time-to-target days at current pace.
- Top-3 risks identified.
- Recommended adjustments.
2.3 The Friday recap
Every Friday by 4 PM local, the VP RevOps publishes a weekly summary:
- 1-paragraph narrative.
- Updated dashboard snapshot.
- Action items from Monday's review with status.
- Alerts on any threshold breach.
3. The Monthly Reforecast
3.1 The first business day of the month
The first business day, RevOps publishes:
- Final-month-prior numbers.
- Variance to plan (volume, conversion, revenue).
- Trailing 13-week trend.
- Updated forecast for current quarter remainder.
3.2 The 90-minute monthly meeting
CRO + CMO + CFO + VP RevOps + heads:
- 20 min — review prior month variance.
- 25 min — current quarter forecast update.
- 25 min — adjustments to MQL volume, conversion targets, headcount, spend.
- 20 min — decisions documented.
3.3 The forecast revision rules
A forecast can only be revised:
- Once per month at the scheduled meeting (no mid-month edits).
- With both CRO and CMO sign-off.
- With CFO awareness if revision shifts material revenue.
Without revision rules, forecasts drift weekly and lose meaning.
4. The Tool Stack
4.1 The 2027 dominant joint-forecast tools
- Clari — 34 percent share among joint forecasting users per Forrester's 2026 Revenue Intelligence Wave. Strong marketing-pipeline integration via HubSpot or Marketo Measure.
- BoostUp — 18 percent share, AI-first revenue intelligence.
- Gong Forecast — 14 percent share, deep call-data integration.
- InsightSquared (Mediafly) — 11 percent share, historical strength in B2B SaaS forecasting.
- Custom Looker + dbt — 13 percent share, common at companies above US$200M ARR.
- Native Salesforce + HubSpot dashboards — 10 percent share, mostly sub-US$50M ARR.
4.2 The integration requirements
- Marketing automation (HubSpot, Marketo, Pardot) → tracks MQL volume and source.
- CRM (Salesforce, HubSpot) → tracks SQL, pipeline, opportunity, closed-won.
- Attribution tool (Marketo Measure, Demandbase, 6sense) → connects marketing touch to pipeline.
- Revenue intelligence tool (Clari, BoostUp, Gong) → aggregates and presents forecast.
4.3 The data refresh discipline
The shared dashboard refreshes:
- Real-time for new MQL counts and pipeline changes.
- Hourly for conversion-rate calculations.
- Daily for full forecast recalculation.
5. Common Joint Forecasting Failures
5.1 Failure — separate marketing and sales forecasts
Marketing forecasts MQL pipeline; sales forecasts revenue. They never reconcile. Fix: single joint funnel model.
5.2 Failure — conversion-rate assumptions hidden
Sales assumes 30 percent MQL-to-SQL; marketing assumes 22 percent. Forecasts differ; nobody knows why. Fix: published conversion-rate assumptions reviewed weekly.
5.3 Failure — no documented reforecast rules
Forecast changes mid-week based on whoever talks loudest. Fix: monthly reforecast cadence with sign-off rules.
5.4 Failure — finger-pointing at quarter-end
"Marketing missed pipeline" vs "Sales missed conversion." Fix: joint accountability with CRO + CMO co-ownership.
5.5 Failure — different tools showing different numbers
HubSpot says one MQL number; Salesforce says another; Clari says a third. Fix: single source of truth via integrated tool stack.
FAQ
Should marketing and sales forecast the same revenue number?
Yes. The 2027 best practice has marketing and sales co-own the same revenue forecast. Marketing's role: drive MQL volume and quality. Sales' role: convert SQL to revenue. Both factors contribute to the revenue outcome; both functions own it together.
How do we handle pipeline created vs revenue closed in joint forecasting?
Track both. Pipeline created is the leading indicator (this quarter's marketing investment drives next-quarter pipeline). Revenue closed is the lagging indicator. Joint forecasting reviews both — pipeline trend predicts revenue 1 to 2 quarters out; revenue confirms the prior period's pipeline quality.
Should we forecast new business and renewal separately?
Yes. New business comes from marketing-and-sales joint funnel. Renewals come from CS-and-renewal-manager joint motion.
The joint forecast covers new business; a separate joint forecast (CRO + CCO) covers renewals and expansion. Pavilion's 2026 dual-forecast data shows companies separating new business from renewal forecasts hit revenue plan 14-percent more often than those bundling them.
What's the right pipeline coverage ratio?
The 2027 standard: 3x at quarter start for B2B SaaS. Below 3x suggests insufficient marketing investment or conversion concerns. Above 4x typically means deal-quality issues (pipeline includes too many low-probability deals). Pavilion's 2026 coverage benchmark sets 3 to 3.5x as the sweet spot for mid-market.
How does AI change joint forecasting?
AI improves joint forecasting in 3 ways: probability-weighted deal forecasts (Gong, Clari) replace rep self-reported commit; pattern-based conversion-rate predictions anticipate trend changes 2 to 3 weeks earlier; automated risk scoring surfaces deals likely to slip before the rep sees it.
The 2027 best practice: AI augments human forecast, does not replace it. CRO + CMO still sign off on the final number.
