Engineering & software · Bangkok, Thailand

We build the systems we wish we’d had.

Business software for small and medium companies, and a version built for engineering firms. Not off-the-shelf software — systems shaped to how your firm already works, by engineers who spent twelve years working around the gaps.

What it does
Practice

Engineering tools

The calculation sheet, the checklist, the document set rebuilt by hand every job — built once, as a tool your team runs.

Each one plugs into YouFlow Eng — or starts a workflow of its own

YouFlow

Business software for small and medium companies. Live in Bangkok and the UAE.

See YouFlow YouFlow EngThe YouFlow wave, continued. One unbroken line writes the w in full, then levels off into a straight run that serves as the crossbar of a lower case e, and curls round to close the bowl of that e.YouFlow Eng

The same product, configured for engineering firms — documents, calculations and approvals in one flow.

What it does Touchstone

The proof piece. Free, no accounts, and it publishes what it cannot claim.

Why one company does both

How the three parts of Zb International fit together One codebase is configured two ways: YouFlow for any business, live with two customers; and YouFlow Eng for engineering firms, live with our own engineering practice and a civil design consultancy. The gaps that surface there decide what gets built next. ONE CODEBASE FOR ANY BUSINESS FOR ENGINEERING FIRMS LIVE LIVE PRACTICE YouFlow YouFlow Eng Engineering practice A vehicle showroom, Bangkok, a procurement firm, UAE Our own engineering practice, a civil design consultancy RUNS THE WORK ON FINDS GAPS

One product, two configurations, and small tools that snap into either — so a firm can start with one job and grow into the whole workflow.

Because the software came out of the engineering.

The sizing spreadsheet on one person’s desktop. Rev C issued while three purchase orders still quote Rev B. The dossier assembled by hand, six weeks late, holding up payment.

Every firm knows about these. Almost nobody fixes them.

The people who understand the problem do not write software. The people who write software have never had a drawing rejected at a hold point. We are both.
