Questions to ask t-shirt and tops manufacturers
Identity and approach
NovaSupplier is infrastructure for direct relationships between independent clothing brands and Portuguese manufacturers.
Use these questions to protect direct brand-factory relationship ownership from the first conversation.
Where brands usually get this wrong
- Relying on intermediaries instead of opening direct conversations with factories.
- Comparing only quoted unit price without validating MOQ per style and timeline realism.
- Treating Portugal sourcing as generic supplier browsing instead of relationship building.
How to use this guide
- Use this guide to structure direct conversations with Portuguese manufacturers.
- Ask identical questions to each shortlisted factory and compare answers line by line.
- Lock ownership of key decisions in writing before moving from sample to bulk.
MOQ and fabric
What is your minimum order quantity per style and per colour?
Jersey MOQs in Europe often start at 50–200 pieces per style. Listen for per-colour vs. total minimums; some factories allow mixed colours to hit one minimum.
Do you source fabric, and what weights and compositions do you stock?
In-house fabric can mean faster lead times. Ask what they stock (e.g. 160–220 gsm cotton jersey, organic, blends) and whether you can supply your own.
Can I get organic or sustainable fabric options at similar MOQ?
Organic and GOTS jersey may have higher minimums or longer lead times. Ask what’s available and at what MOQ.
Do you offer sample or development runs before bulk?
Sample runs (e.g. 20–50 pieces) help test fit and print. Ask minimum for sampling and whether the same factory does bulk.
Print and decoration
Do you do screen print, DTG, or embroidery in-house?
In-house decoration simplifies logistics. Ask what they offer and minimums per placement (e.g. 50 pieces per print).
What file formats and colour specs do you need for print?
Get their art specs (e.g. CMYK, DTF-ready) and lead time for print setup. Misalignment here can delay production.
What is your policy on reprints if print quality is off?
Clarify who bears the cost of reprints and whether they do pre-production print approval.
Lead times and quality
What is your typical lead time from order confirmation to delivery?
Basic jersey often runs 4–8 weeks; add time for custom fabric or print. Get a breakdown: fabric, cut, sew, print, pack.
What quality checks do you do (e.g. measurements, stitch quality)?
Listen for measurement reports, stitch checks, and whether they do inline or final inspection.
How do you handle size grading?
Ask if they grade in-house and whether you need to provide grade rules. Consistency across sizes matters for tops.
