I’m finalizing the acquisition of a facility management services business through an asset sale and need advice on handling Contract assignments. The seller prefers to wait until the first day of the transition to process these assignments, which makes sense from their risk mitigation perspective in case the deal doesn’t close.

However, I’m concerned about how to manage the transition period before the assignments and corporate approvals are finalized. How can I ensure continuity of service for key accounts during this interim phase?
In some cases, there are no contracts, rather service agreements, but corporate approval is still required for us to be recognized as a vendor.

I’d appreciate any advice.
