Build vs Buy AI
The commercial decision between commissioning custom AI software (build) and licensing an off-the-shelf AI product (buy), with the right answer depending on workflow specificity, regulatory constraints, integration depth, and total cost of ownership.
How it works
The build vs buy decision is the strategic question UK businesses face once they move past initial AI experimentation. The right answer is not always build. Commodity workflows with standard integration patterns and unregulated data are often well-served by off-the-shelf SaaS. Workflows with specific integration requirements, regulated data, or strategic differentiation usually need build. The total-cost-of-ownership calculation matters: SaaS pricing is per-seat or per-task, scaling badly with volume; custom software is a one-time build plus ongoing engineering, which usually wins on multi-year horizons for high-volume workloads. Ayoob AI engages with this decision honestly and will tell clients when buy is the right answer.
