If you're ready to launch or relaunch your business for sale it's imperative you have prepared the relevant business information for any prospective buyers. One of the key reasons businesses fail to sell is due to the lack of preparation, many of the best buyers are in the market and ready to transact so when you go live they expect to see a business that's prepared and ready to go into due diligence.
Check and double check everything, even the slightest mistakes or missing information, including delays, are deal killers and should be avoided at all costs.
The bottom line, never go live until you're 100% ready to enter into full due diligence.
