When I build a document-processing pipeline, AI is one component in the stack — not the entire architecture.

Take bank-statement PDF-to-digital conversion. In the field, I would rather ship a deterministic system: rule-based parsing, fixed output schemas, validation gates, full audit trails, and an LLM or CV model called only as a fallback for edge cases.

The output is deterministic, reviewable, and can be reconciled line-by-line against the original statement. You are not handing a black-box model the whole document and hoping the numbers come back right.

Why this matters in production:

A system like this can be developed cheaply — we are talking around USD2 in AI-assisted development cost — and then reused across thousands of SME deployments. The cumulative savings are massive.

Compare that with an AI-only approach:
Higher per-run cost.
Heavier infrastructure footprint.
No guaranteed accuracy.
Harder to audit and debug.
Harder to scale without drift or failure modes.

AI should not replace solid systems engineering.

AI should help us build cleaner systems — cheaper to deploy, faster to iterate, more accurate in production, and genuinely useful for the operators running the business.

For SMEs, that is the real value. Not the hype cycle. Not FOMO-driven tooling. Just systems that work on real data, in real environments, every day.
