If you have a deal under LOI, put a weekly recurring hour-long meeting with the seller in the calendar until closing.
This is a best practice to ensure regular communication, remain aligned, stay on track, build the relationship, and avoid back-and-forths on scheduling.
Some weeks you may have nothing to discuss and you’ll wrap it up in 3 minutes. Other weeks you may include your QoE or legal advisors, which is easier to arrange since you don't have to deal with multi-party scheduling.
