Most final offers fall within a 1x-1.5x multiplier of yearly profit. This usually entails an initial payout with the remainder paid out within 2-3 months.
The offer and contract will usually be dependent on agreeing to a payout schedule, sharing financial responsibility of clients who churn shortly after the acquisition, working with us in the transition plan, helping when necessary with any official announcement plan, etc.
Some deals are worth less and some more, but this is most likely what you can expect with regards to a final offer.
Ex: If your business made $20,000 of profit over the last 12 months, you can expect a final offer of $20,000-$30,000 (barring anything that significantly increases or decreases the worth of your business).
