Operation
If your software has many bugs, the clients will lose trust. An unstable product is bad for business.
So, you'll put extra effort to catch these bugs before the client sees the next version, right? Well, this will increase your costs, slow down your shipment, and masquerade the issue. Soon, your product will be costing so much and taking so long to evolve.
Instead of stabilizing something unstable, a better strategy is to build something stable by hiring an experienced developer that can actually say no for bad ideas. A different point of view can eliminate many risks, but someone that never disagrees with you with arguments will jeopardize your business.
Marketing
Your client may not believe in you if he doesn't know you, and he won't know you if he doesn't believe in you. Kind of a catch 22, right?
You need a wingman, someone that vouch for you. It can be a platform, it can be a supplier that provides an API or infrastructure. This not only reduces the complexity of your enterprise, but also gives you credibility.
Normally the partner will take part of your margin, but it's better to have a smaller margin than no margin at all when you have no credibility.
Finance
Instead of planning the wedding before actually going on a date, go on a date first, ask what your partner wants for dining and split the bill.
That's why the SaaS model has become so popular nowadays. Instead of spending thousands of dollars in R&D to sell off-the-shelf software, the idea is to get the client in the loop and to sell technical hours instead.
The icing on the cake is that you can split the technical hour cost across clients that want something similar. But, for this to work out, the fewer clients you have the better because you need eye to eye communication or hire an entire data analysis department to decipher what they want, so start focusing on high-ticket clients.
