Once complete, the infra team will assign the issue back to the #g-sales board.

+### Proposals sent <30 days 
+Every week, any proposal not sent within 30 days of its creation in Salesforce should be closed lost. The review of these opportunities and exceptions for them of one (1) week or less are the responsibility of the sales manager.  For exceptions of more than one week, escalate to the CEO.

+### Sales retrospectives
+Every week, any closed lost new business or expansion opportunity from the previous week, as well as any opportunity with a closed lost date pushed into subsequent quarters, is discussed in a meeting between the AE or CSM who lost the deal, their manager, the head of marketing, head of digital experience and the CEO.  SC does not attend. This meeting should include any notes regarding the closed lost reason. When no deals are closed lost from the prior week, the meeting is used to discuss the oldest top opportunities and try to get them out of the pipeline.
