Hi…you may have tried this so apologies.
Advertise the hosting costs upfront on your website (assuming you have one :)) so it does not come as a surprise to clients.
They should therefore be aware of the cost before they even start dialogue with you.
If they can’t afford it then perhaps these clients are not the ones you want?
What kind of business or business model can’t afford $5 per week ($20 pm CMS) to market their business/services? How much is a Starbucks coffee now a days at least a couple of dollars I imagine, perhaps this is a good camparision to make.
Businesses need to understand the value they are getting if they haven’t the budget then they should look elsewhere we should not compromise.
If their website ultimately brings in paying clients then there is a clear return on investment, it’s not money down the drain. Trouble is everyone wants something for nothing it is not realistic if they want a solid, quality product.
Be upfront early on with monthly costs so you don’t get clients who either don’t want or can afford the hosting cost. It should not be a surprise.
Explain the benefits of hosting with Webflow.
Tell them it’s ONLY $5 per week, and compare that with something like the price of a cup of takeaway coffee.
Just my thoughts
