Why are two quotes for the same project so different?

Different vendors make different assumptions about scope, quality, testing, and team seniority. A low bid may assume a thinner feature set, less testing, or junior developers, while a higher bid may include design research, automated testing, and senior engineers. Ask each vendor to document their assumptions in writing so you are comparing the same thing.

Is it cheaper to use an off-the-shelf product instead?

Often yes, at least initially. If a SaaS product covers 80 percent or more of your needs, it is usually the smarter first choice. Custom software makes sense when your process is a genuine competitive advantage, when existing tools force expensive workarounds, or when per-seat licensing costs eventually exceed the price of owning your own system.

How long does a typical B2B custom software project take?

A focused tool might take a few weeks to a couple of months, a mid-sized application commonly takes three to six months, and a complex platform can run six months or more. Timeline and cost move together: compressing a schedule usually means adding people, which raises cost and coordination overhead rather than proportionally reducing time.

How can I keep the budget under control?

Start with a tightly scoped first release that delivers real value, then expand based on usage. Insist on regular demos and short feedback cycles so problems surface early, when they are cheap to fix. Keep a prioritized backlog and a change process so new ideas are evaluated against budget rather than absorbed silently.

Should I pay for a discovery phase before committing to a full build?

For anything beyond a simple tool, a paid discovery phase is usually worth it. It produces a clearer scope, a more accurate estimate, and often a prototype, which reduces the risk of expensive surprises later. Think of it as buying certainty before you commit the larger budget.
