In a pure B2B SaaS business walk me through the difference of new/upsell bookings vs new/upsell ARR

In a pure B2B SaaS business, the difference between new/upsell bookings and new/upsell ARR can be subtle but important, even when there is no services/implementation component and you're focusing on annual figures (ACV, not TCV). Here's how to think about it:

1. New/Upsell Bookings:

   • This represents the total value of contracts signed during a specific period (e.g., annually).
   • Bookings include all the revenue committed by the customer for the year, regardless of when the revenue is recognized.
   • If a customer signs a contract for $120,000 ACV, the full $120,000 would be considered as bookings for that year.

2. New/Upsell ARR:

   • ARR (Annual Recurring Revenue) reflects the recurring revenue that a SaaS company expects to recognize annually from its subscription contracts.
   • ARR is a normalized metric that excludes one-time fees or non-recurring components. It focuses purely on the recurring subscription revenue.

Key Differences:

• Timing of Recognition:

  • Bookings are recognized when the contract is signed, while ARR reflects the annualized recurring revenue that will be recognized over time.
  • For example, if a customer signs a contract in December for $120,000 ACV, the full $120,000 would count as bookings for that year, but only $10,000 (1/12th) might be recognized as ARR for that year, depending on the start date of the subscription.

• One-Time Adjustments:

  • If there are any one-time discounts, credits, or adjustments applied to the contract, these might impact bookings but not ARR. ARR focuses on the recurring portion of the revenue.

• Renewals and Upsells:

  • Upsell bookings might include additional features or services added to the contract, which could inflate bookings compared to ARR if those upsells are not fully recurring.

When One Would Be Higher:

• Bookings > ARR:

  • This happens when contracts are signed late in the year, and the full value of the contract is counted as bookings, but only a portion of it contributes to ARR for that year.
  • Example: A $120,000 ACV contract signed in December would count as $120,000 in bookings but only $10,000 in ARR for that year.

• ARR = Bookings:

  • This occurs when contracts are signed at the start of the year, and the full annual value contributes to both bookings and ARR.

Are They the Same?

• In a scenario where all contracts are signed at the beginning of the year and there are no timing differences or non-recurring components, new/upsell bookings and new/upsell ARR could align. However, in most real-world cases, timing differences and adjustments will create a gap between the two metrics.

This distinction is critical for SaaS businesses to understand revenue timing and growth trends accurately.
