Why us

A specialist practice, not a general engineering firm

Pharma and nutraceutical manufacturing is the whole business. That changes what you get.

About the practice
01Direct GMP Auditor oversight
The work is led by a GMP Auditor, not delegated to a junior engineer. Compliance risk is assessed by someone who has sat on the audit side of the table.
02Hands-on facility and equipment experience
Specification, installation and commissioning are done by people who have physically stood the equipment up - so the design accounts for how it actually gets built.
03One point of contact, setup through maintenance
Facility design, formulation, equipment and ongoing preventive maintenance run through a single relationship. No handoff gaps between vendors.
04Specialist scope, not general engineering
Pharma and nutraceutical manufacturing is the entire practice. There is no general-contracting division that treats cGMP as an edge case.
Industries we serve

Two verticals, two different problems

The manufacturing discipline is shared. The regulatory pressure and the pace are not.

Common questions

Questions we get before the first call

If yours is not here, ask it directly - the first conversation is a technical one, not a sales one.

01

What does a GMP compliance consultant do?

A GMP compliance consultant designs facilities, processes and documentation systems to meet current Good Manufacturing Practice requirements, then verifies they hold up under regulatory inspection. Ztech Consulting & Tech Inc covers facility setup to FDA cGMP guidelines, corporate SOP development, equipment qualification and process validation, led directly by a GMP Auditor.

02

Do you serve both pharmaceutical and nutraceutical manufacturers?

Yes. Ztech Consulting & Tech Inc works with both pharmaceutical and nutraceutical manufacturers. Pharmaceutical engagements focus on FDA audit readiness, equipment validation and documented SOPs; nutraceutical engagements focus on formulation flexibility and scaling from small-batch to full production.

03

What areas does Ztech Consulting & Tech Inc serve?

The practice is based at 240 Ronkonkoma Ave, Ronkonkoma, NY 11779, serving Suffolk and Nassau County and the wider New York, New Jersey and Connecticut region, with project work accepted nationwide.

04

Can you help a startup entering pharmaceutical manufacturing?

Yes. New business development is one of the five service disciplines. It covers product line assessment, tablet, capsule, blending and mixing and coating line planning, and a capital and compliance roadmap - so the cost and regulatory burden are understood before capital is committed.
