In this case it all depends on how much value it will bring as every business is different, so try and estimate how many clients will use this, how much time that will save the business and therefore how much they may be willing to pay for it. One option is to have a meeting with them and without telling them a price, try and gauge how much value they think it will bring the business. If they ask about price, tell them it depends on what features they want to try and get more information out of them. If they pay for online ads then that is a really good sign, because you can discuss how it can increase conversion rates, so it will actually save them money on ad spend. However, if your business is new you may just want to get the clients at whatever cost and there's nothing wrong with that. Perhaps offer them a really affordable 3 month trial (making it clear the pricing is only temporary), then you can reassess pricing based on its success. That can then lead to more business and you could sell the same bot to other similar businesses.
