Best case sits between commit and pipeline. Commit is the near-certain floor. Pipeline is the uncommitted universe. Best case is the if-everything-breaks-right number in the middle.
A best case forecast is the optimistic ceiling tier of a sales forecast. It is the number a rep would book if every open deal they are actively working lands in the quarter and nothing breaks the wrong way. RevOps rollups typically weight best case at 50 to 70 percent probability, well above pipeline and well below commit. It is the stretch number, not the committed number.
The six things every operator should know before using the best case tier in a weekly forecast.
A best case forecast is the sum of every open deal that would close if conditions break right across the quarter. It is a stretch number, not a commitment. Reps and managers submit it alongside commit so leadership sees both the floor and the ceiling. The gap between them is the forecast band.
Most revenue teams treat best case deals as 50 to 70 percent likely to land. The weight is lower than commit, which usually sits above 90 percent, and higher than pipeline, which sits below 40. The exact number varies by team maturity and historical conversion, but the band is standard across modern B2B sales orgs.
Every modern forecast splits open revenue into three bands. Commit is the near-certain floor the rep bets the quarter on. Best case is the stretch ceiling if everything breaks right. Pipeline is the broader universe of deals still being worked. Reporting all three separately shows the confidence band instead of a single flat number.
Reps assign each open deal to a category on their weekly submit. Managers review the categorization during the Monday rollup and challenge deals that look mis-sorted. Leaders see the stacked rollup with commit, best case, and pipeline totals side by side. The categorization is the primary editorial act of the forecast cadence.
A deal lands in best case when the signals are strong but a specific risk is open. Common patterns: verbal commitment without signed paper, legal review open, procurement scheduled but not confirmed, or a champion signal without executive sign-off. The deal is real. The timing is not locked. That is the shape of a best case deal.
Mature revenue teams track the rate at which best case deals convert to commit over the course of the quarter. Above 60 percent conversion means the categorization is honest. Below 40 percent means reps are using best case as a parking lot for deals that should sit in pipeline. The conversion rate is a scored metric worth watching.
Best case does not stand alone. It only makes sense inside the three-tier forecast model that modern B2B revenue teams run. Here is how each tier is defined, how the probability weights stack, and how deals move between them across the quarter.
Commit is the number the rep bets the quarter on. These are deals with signed paper, confirmed timelines, or ironclad verbal commitments with no open dependencies. RevOps rollups weight commit above 90 percent and often treat it as 100 percent when summing the forecast. The commit number is what the manager carries to the leader review.
Best case is the stretch tier. These deals are real and active, but a specific risk or dependency is open. The weight band is 50 to 70 percent, giving leadership a view of what the quarter could look like if the open risks resolve. Best case is the if-everything-breaks-right number.
Pipeline is every open deal in the quarter that has not been categorized up to best case or commit. It includes early-stage opportunities, deals with weak signals, and deals whose close date lands in the quarter but whose fundamentals are still being validated. Pipeline is the top of the funnel inside the forecast period.
Omit is the explicit zero. The deal is open in the CRM but the rep is telling the manager it will not close this quarter. Omit matters because the alternative is silence. Without an explicit omit category, deals that are quietly dead stay in pipeline and pollute the rollup. Omit is a positive act of forecasting hygiene.
The spread between the commit floor and the best case ceiling is the forecast band. A tight band means the quarter is predictable. A wide band means the quarter has material upside or material risk depending on which open dependencies resolve. The band is what the leader review focuses on, not the point estimate.
A healthy forecast has deals walking up the tiers as the quarter progresses. Pipeline deals move to best case when risks start resolving. Best case deals move to commit when paper is signed or dependencies clear. Slippage runs the other way. The weekly cadence captures this movement, which is more informative than any single snapshot.
The best case tier breaks when reps use it as a parking lot. The whole point of a three-tier model is that each tier has an honest definition reps and managers agree on. Here are the shapes of deals that belong in best case and the shapes that do not.
The buyer has said yes on a call. The contract is in legal review or sitting in a procurement queue. The timing to signature is reasonable but not confirmed. These are classic best case deals. They are not commit because the signature event is still outstanding. They are not pipeline because the economic decision has been made.
The champion inside the account is fully bought in and has run the internal process. The remaining risk is one executive signature, usually CFO or CEO. If the exec meeting is calendared, the deal belongs in best case. If the exec is unaware the deal exists, the deal belongs in pipeline. The sign-off risk is real but bounded.
The buyer has committed to the deal but is waiting on a specific event, a budget cycle, a quarterly board meeting, or a related procurement decision. The event is calendared inside the quarter. Best case is the right tier because the deal is real and the timing is bounded. Commit requires the event to have cleared.
A deal with weak signals, no verbal commitment, no identified champion, or no close plan does not belong in best case. It belongs in pipeline. Reps often promote these deals to best case to make the number look stronger. The pattern is called sandbagging in reverse, and it degrades the forecast within one or two quarters.
The reverse pattern. A deal the rep has in commit that no longer feels locked should drop to best case, not stay in commit. The best case tier exists precisely to catch deals whose risk profile has shifted. Reps who refuse to move slipping deals down the tiers protect the number this week and torch accuracy next quarter.
If the probable close date is in a future quarter, the deal does not belong in this quarter's best case at any tier. It belongs in future quarter pipeline. Pulling future-quarter deals into current best case to lift the ceiling is the second most common forecasting failure mode. Clean close dates kill the behavior.
The best case total is one of the two anchor numbers in every leader forecast review. Leaders read it as a signal of upside, of risk, and of forecast hygiene. Here are the patterns experienced VPs and CROs look for when the best case line hits the rollup.
When the gap between commit and best case is small, the quarter is predictable. The upside is bounded, the downside is bounded, and leadership can plan hiring, cash, and board updates against a tight range. Narrow bands show up when the pipeline is late-stage heavy and most risks have already resolved.
When the best case ceiling is far above the commit floor, the quarter can swing hard either way. Leadership looks at the specific deals sitting in best case and asks which open risks are blocking the move to commit. The wide band is not bad on its own, but it is the signal to spend review time on the gap deals.
A best case total that rises week over week during the quarter is a healthy signal. It means pipeline deals are being promoted up as risks resolve. The flow should look like a conveyor belt: pipeline to best case to commit. If best case grows but commit is flat, the conveyor is stuck at the final stage.
A best case total that falls week over week during the quarter is the opposite signal. Deals are either slipping out of the quarter entirely or dropping back to pipeline as risks grow. Leaders look at which deals left and why. The pattern often correlates with pipeline coverage problems that will hit the following quarter.
When a rep's best case equals their commit, the rep is telling leadership they see no upside this quarter. Everything they expect to land is already in commit. Sometimes this is honest. Often it is sandbagging and the rep is hiding deals in pipeline or omit to protect themselves. The pattern deserves a direct conversation.
When best case is more than twice commit, the rep is leaning on the upside story to compensate for a weak commit. Leadership pressure tests the specific deals sitting in best case and asks what has to be true for even half of them to convert. The ratio is a tell, not a verdict, but it earns a close look.

Commit is the near-certain floor, deals the rep is betting the quarter on at 90 percent or higher probability. Best case is the optimistic ceiling, deals that would land if conditions break right at 50 to 70 percent probability. Commit is a promise. Best case is a stretch. Leadership reviews both to see the forecast band, not just a single number.
Most B2B revenue teams weight best case deals at 50 to 70 percent probability in rollup math. The exact number varies by team maturity, historical conversion data, and sales cycle length. Below 50 percent, the tier blends into pipeline. Above 70 percent, it blends into commit. The 50 to 70 band is the industry-standard middle ground.
Pipeline is every open deal in the quarter that has not been promoted to best case or commit. It carries 10 to 40 percent probability in most rollups. Best case is the subset of pipeline that the rep has explicitly promoted up because the signals are stronger than typical open pipeline but a specific risk is still open. Pipeline is the universe. Best case is the curated top slice.
A deal moves from pipeline to best case when the economic decision has essentially been made but a bounded risk is still open. Classic triggers: verbal yes with no signed paper, champion locked with executive sign-off pending, or deal gated on a calendared timing event like a budget cycle or board meeting. If the risk is unbounded, the deal stays in pipeline.
A deal moves from best case to commit when the open dependency clears. Paper gets signed, exec sign-off is confirmed, the budget cycle approves, procurement signs off. The event that was blocking the deal from being near-certain has resolved. If the event has not happened, the deal stays in best case regardless of how optimistic the rep feels.
Yes, and healthy forecast hygiene requires it. If a deal in best case loses its champion, hits an unexpected legal objection, or runs into a stakeholder change on the buyer side, the deal drops back to pipeline until the new risk is understood. Reps who refuse to drop deals back down the tiers trade short-term optics for next-quarter accuracy damage.
Mature revenue teams target best case to commit conversion above 60 percent each quarter. Above 60 percent means the categorization is honest and reps are promoting deals up only when the signals warrant. Below 40 percent means best case is being used as a parking lot and the categorization is noise. The conversion rate is worth tracking as a per-rep metric.
Most mature B2B CRMs ship a forecast category field with commit, best case, pipeline, and omit as the default values. Spreadsheet-based forecasting usually models the categories as columns or tabs. The must-have is that the category is a first-class field on the opportunity, editable by the rep, visible in the rollup, and locked by the weekly submit cadence so it cannot be edited retroactively.
