Every US business making a software decision is really making two decisions: whether to build or buy, and if they build, who builds it and how.
The first decision gets most of the attention. The second one determines whether the first decision pays off.
This post walks through both — because the build vs. buy question is genuinely nuanced, and the "who builds it" question has become more important as the market for development talent has fragmented significantly over the last decade.
The build vs. buy decision: what the frameworks miss
Most build vs. buy frameworks focus on upfront cost. Buy the SaaS tool: pay the subscription, skip the development investment, be live faster. Build custom: pay for development, wait longer to go live, but own the asset.
That framing is accurate as far as it goes. But it misses a few things that matter enormously to the companies that get this decision wrong.
These aren't hypotheticals. They're patterns that come up consistently among US businesses that have had this conversation.
The US has more software development talent than anywhere else in the world. It also has some of the highest development costs. A senior software engineer in San Francisco costs $180,000–$250,000 per year in fully loaded compensation. For a product that needs a team of four, that's a $700,000–$1,000,000 annual spend before infrastructure, tooling, or management overhead.
This is why a significant portion of US custom software development is built with offshore or nearshore teams — not because US talent isn't excellent, but because the economics of building a full in-house team don't make sense for most companies unless software is the core product.
The offshore development model for US companies has matured considerably. The failure modes that defined the space a decade ago — communication breakdowns, quality problems, misaligned expectations — are largely a function of engagement structure, not geography. A well-structured offshore engagement, with a clear scope, experienced senior developers, proper QA, and an account management layer that keeps the communication functioning, delivers strong results consistently.
The questions worth asking when evaluating a US offshore development partner:
A growing category of custom development work among US clients is building SaaS products — software businesses that are themselves selling a software-as-a-service. This is a different engagement than building internal operational software, and it deserves its own consideration.
Building a SaaS product with an offshore development partner can be an excellent path to a fundable MVP, particularly for non-technical founders who have validated the market but don't have the budget to hire a full engineering team in the US market.
The keys to making this work are a very clear product specification (user stories, wireframes, and defined scope — not a vague brief), an experienced partner who has built SaaS products before and can contribute to architecture decisions rather than just executing instructions, and a realistic timeline. A competent team can build a meaningful MVP in three to six months. Anyone promising a full-featured product in six weeks is either misunderstanding the scope or setting you up for disappointment.
A well-run custom software engagement for a US client follows a recognisable pattern.
It starts with a discovery phase — typically two to four weeks — in which the development partner works with the client to define the scope, the technical architecture, and the delivery plan. This phase produces a specification document and a project plan with milestones. If a partner wants to skip this and go straight to development, that's a warning sign.
Development then proceeds in sprints — typically two-week cycles — with working software demonstrated at the end of each sprint. This gives clients regular visibility into progress and creates natural checkpoints for feedback and course correction.
QA runs in parallel with development, not at the end. The bugs found during a sprint are fixed before the next sprint starts, not accumulated into a final testing phase that always gets compressed when the deadline approaches.
Deployment and handoff are planned, not improvised. The client's team needs to understand what they've received, how to operate it, and who to call when something needs to change.
The bottom line for US businesses
Custom software is not for everyone. If an off-the-shelf tool does what you need, buy it. The total cost of ownership is lower, the implementation risk is lower, and the time to value is shorter.
But if you're consistently fighting your tools, building workarounds, or leaving competitive advantage on the table because your software can't encode your process — custom development is worth a serious evaluation.
The right partner makes an enormous difference. Not just in the quality of the software, but in whether the whole experience is one you'd do again.
