Beating a dead horse here but this is critical for our company as well. We're a life sciences service provider and provide estimate of services before converting estimates to quotes.
We currently use Freshbooks soley for this feature. I'd like to get this all into one platform and spend my money with Square but I simply can't until we have this.
Freshbooks has a very intuitive way that I believe Square could replicate. Effectively, the invoice and estimates are treated in the same fashion with the caveat that estimates cannot be paid upon. Once a client has agreed to an estimate, we simply hit "Convert to Invoice" and we can then take payment. This allows us to restructure estimates as much as we want until we come to an agreement and invoice the customer.
