After completion, there are some practical steps to finish the deal properly, and some ongoing commitments to your lender and the seller.
Straight after completion
- Stamp duty: pay any stamp duty on a share purchase, or property tax on property. See Is there stamp duty when you buy a business?.
- Companies House: update the directors and people with significant control.
- Security: the lender's charges are registered at Companies House within 21 days, usually by the lender's solicitors.
- VAT: if the deal was a transfer of a going concern, sort out the VAT registration. See Is there VAT on buying a business? Transfer of a going concern.
- Banking and contracts: update bank mandates, insurance, and any contracts or licences that need your details.
Ongoing
- Lender reporting: send the financial information your facility agreement requires, such as management accounts, and stay within its covenants.
- Seller payments: make deferred or vendor loan payments on time, and only as the lender allows. See How do lenders treat a vendor loan?.
- Earn-out tracking: keep clear records of the figures the earn-out is measured on. See How does an earn-out work when buying a business?.
