All services
  1. 01

    Product screening

    Tell us the product, market and target price. We screen the factory network and shortlist what actually fits — not every listing that matches a keyword.

  2. 02

    Best price

    We compare quotes and break down material, labour, tooling and freight, then negotiate the best workable price for the volume and specification.

  3. 03

    Samples

    Sample units and test reports before you commit. We manage revisions, approval and the gap between the sample and the production build.

  4. 04

    Factory verification

    We check the factory is real, review its business licence and relevant certifications, verify references and visit or audit the production site.

  5. 05

    Production follow-up

    We follow the schedule, materials, changes and issues on the line, and keep you updated with photos and written reports.

  6. 06

    Inspection

    In-line and pre-shipment inspection against agreed acceptance criteria, with a photo report and corrective actions before dispatch.

  7. 07

    Shipping & logistics

    Consolidation, export documents, freight booking and door-to-door delivery — one shipment and one document set for multiple factories.

  8. 08

    After-sales support

    We stay on the order after delivery: replacements, corrective actions, spare parts and factory follow-up.

  9. 09

    Technical documents

    Datasheets, drawings, test reports, certificates, packing lists and customs documents, prepared for your engineering and compliance teams.

  10. 10

    Product improvement

    Cost-down, material substitution, packaging and design changes to improve the product, the margin or the production yield.

Five steps. No black boxes.

Every stage has an owner, a document and a date. You see the same information we do — specifications, sample results, inspection records and shipping documents.

  1. 01

    Product brief

    Tell us the product, target price, market and volume — stock or custom. A photo, reference link or drawing is enough to start.

  2. 02

    Factory screening

    We shortlist real factories, verify licences and capability, compare quotes and return a cost breakdown with the options.

  3. 03

    Sample & approval

    Samples, test reports and revisions; we confirm the specification and acceptance criteria before production.

  4. 04

    Production & inspection

    We follow the line, inspect against the agreed criteria and prepare the technical file before packing.

  5. 05

    Shipping & after-sales

    Consolidation, export documents, freight and after-sales support — one accountable partner after the container leaves.

Lead times are confirmed in the quotation after the specification and sample stage. We reply within 12 hours.

Real factories. Real documents.

Factory verification, inspection records and technical files stay with the order. Before a deposit we check who the factory is; before shipment we check what is in the box.

How verification works
  • 01

    Factory verification

    Business licence, factory address, references, certifications and on-site capability are checked before a deposit.

  • 02

    In-process follow-up

    Materials, changes and critical assembly steps are tracked against the approved specification while the order is running.

  • 03

    Pre-shipment inspection

    Finished goods are inspected against the agreed acceptance criteria, with a photo report before dispatch.

  • 04

    Technical file

    Datasheets, drawings, inspection records and shipping documents are kept with the order and shared on request.
