How to Choose a Sportswear Manufacturer: 12-Point Checklist

The 12-point checklist at a glance

The checklist is the whole method: twelve points, one question each, one piece of evidence each. Put the same questions to every shortlisted supplier in the same order and keep the written replies, because a comparison is only fair when each manufacturer has answered the same thing in the same words.

The sections below explain what a sound answer looks like on each point, and how ZipaSports, a custom sportswear factory in Sialkot, Pakistan, answers them. The scoring table at the end turns the twelve answers into a number you can compare across suppliers.

Point 1: is it a factory or a trading company?

A factory owns the cutting, sewing and decoration that make your garment; a trading company buys that capacity from someone else and resells it. Neither is dishonest, but you need to know which one you are paying, because a trader adds a margin and a layer between your brief and the machine operator.

The test takes ten minutes. Ask for a live video call, not a recorded clip, and ask the person to walk from the cutting table to the sublimation press to the sewing line while you watch. Ask what fabric is on the table today and which order it belongs to. A trader offers a call with the factory at a later date; a factory holds the phone up now.

Three more tells: a factory quotes fabric by composition and GSM without checking with anyone, it can say which print or embroidery method a particular logo needs, and its address is an industrial unit rather than an office suite. ZipaSports runs its own cutting, sublimation, embroidery, screen printing and sewing lines at Talwara Mughlan and gives video tours on request. The three routes are compared in factory vs trading company vs marketplace.

Points 2 and 3: the MOQ policy, then mockup and sample terms

A minimum order quantity should be stated once, per design, and should not change between the website, the sales reply and the quotation. If three documents give three numbers, the supplier is guessing or pooling your order with someone else's. Ask what happens below the minimum: a factory with its own cutting can often run a smaller lot on request, while a trader usually cannot.

ZipaSports' policy is MOQ 20–25 pieces per design, lower on request, and no MOQ limit for sportswear brands. Mixed sizes count within one design. Background is in MOQ explained for apparel startups.

On mockups and samples, ask for three written answers. Is the digital mockup free, and how long does it take? Is the physical sample charged, and is that cost credited against the bulk order? How many revisions are allowed before approval? A supplier that charges for the mockup is charging you to find out whether it understood the brief. At ZipaSports the digital mockup is free, returned within 24 hours, with unlimited revisions; a physical sample takes 5–7 days, is charged at sample cost, and that cost is adjusted against your bulk order. No serious factory gives physical samples away, so treat a promise that they cost nothing as a reason to ask more questions. Details: free 24-hour design mockup.

Points 4 and 5: fabric GSM on paper, decoration in-house

A manufacturer that will not put fabric composition and weight on its quotation cannot be held to either later. GSM is grams per square metre; it tells you whether a jersey is a light match shirt or a heavier training top, and whether leggings will stay opaque under load. Ask for the number against every garment on the quote, then weigh a 10 cm square of the sample if you want to confirm it.

Decoration is the second half of this point. Sublimation, screen printing, embroidery, DTF, puff print and heat transfer each need different equipment, and when a supplier sends one of them out, that step leaves its quality control and its timetable. ZipaSports runs all six in-house in Sialkot. Full option ranges are on the fabrics reference and printing methods pages.

Points 6 and 7: quality control and a written guarantee

Ask where the checks happen, not whether they happen. Every supplier says it checks quality; a factory can name the checkpoints: fabric inspection before cutting, print check against the approved mockup, in-line sewing inspection, measurement check against the approved size specification, and final inspection before packing. Ask whether wash-fastness and colour-fastness are tested on sublimated fabric and whether pre-shipment photos are available. ZipaSports lists its checkpoints on the quality control page.

A guarantee only counts if it is written, defines a defect, and names the remedy and the timescale. Read the exclusions as closely as the promise. Normal shade tolerance between dye lots and a measurement tolerance of about ±1–1.5 cm are standard across the industry, and a supplier that promises zero tolerance is over-promising.

ZipaSports' Quality Guarantee: if any garment arrives with a manufacturing defect, we remake it free of charge — the remake goes into production within 3 days of your report. Print faults, stitching faults, wrong size against the approved spec and wrong garment or quantity are covered; send photos and the order reference within 7 days of delivery. Full terms: quality guarantee.

Points 8 and 9: lead times by stage, and how fast they answer

"Four weeks" is not a lead time; it is an average of things you have not been told. Ask for each stage separately, in business days, and ask what starts the clock, because most factories count from design approval rather than from your first message.

Reply speed predicts how the order will go. Send one technical question, for example which GSM and knit they would use for a sublimated netball dress, and time the answer. A production office replies in hours with a number; a sales desk replies in days with an adjective. ZipaSports answers on WhatsApp within 2 hours during business hours and by email within 24 hours, Monday to Saturday, 9:00 to 18:00 PKT. See how long custom sportswear takes.

Points 10 and 11: certifications you can verify, and export paperwork

Certification logos on a website are images; certificates are documents with an issuing body, a scope, a date and an expiry. Ask for a copy of each one claimed, check that the company name on it matches the company you are paying, and check that the scope covers garment manufacturing. For sportswear the ones that matter are a quality-management certificate (ISO 9001:2015), a social audit (BSCI) and fabric testing (OEKO-TEX Standard 100), with GRS if you want recycled polyester. ZipaSports holds ISO 9001:2015, OEKO-TEX Standard 100 tested fabrics, a BSCI audit, GRS recycled options and SGS testing, and is a Government of Pakistan licensed exporter; certificate copies are available on request via the certifications page.

Export documents decide whether your parcel clears customs or waits in a bonded warehouse while someone finds a form. Ask which documents are issued as standard: a commercial invoice, a packing list and a certificate of origin are the minimum for imports into the UK, EU, USA, Canada and Australia. Ask who the importer of record is and whether the courier clears customs. ZipaSports issues all three with every shipment; who pays duty and VAT is explained in import duties and shipping from Pakistan.

Point 12: references, a video tour and payment terms

References help only when you can check them and when they resemble you. Ask for a reorder rather than a first order: a club back for a second season or a brand on its third drop tells you more than any first-time buyer. Where a supplier cannot share client names, which is normal in private-label work, ask instead for a video tour of work in progress and pre-shipment photos of a recent order with the labels covered. ZipaSports does both on request from its Sialkot floor and does not publish client names.

Payment terms belong on the quotation, not on a web page, because they vary with order value, buyer history and destination. What you can check in advance is whether the terms are stated before you commit, whether any deposit is tied to a milestone such as sample approval, and whether the balance falls before or after shipment. Be cautious of any supplier asking for full payment before a mockup is approved. ZipaSports confirms payment terms and a full quotation with each enquiry; nothing is priced on the site because every order is quoted to its own fabric, quantity and decoration. Reach the production office through the contact page.

Scoring table: compare three shortlisted manufacturers

Score each supplier from 0 to 2 on every point: 0 for no answer or one that contradicts another source, 1 for a verbal answer, 2 for a written answer with evidence. Weight the points that matter most to you: a school weights lead time and sizes, a startup MOQ and labels, a distributor export documents and reorder consistency.

A supplier that scores 20 or more out of 24 on written evidence is a reasonable place to send a sample order; below 14, walk away whatever the price. ZipaSports wrote this table so that buyers can score it too. Every answer above is on this site or available on request from the production office in Sialkot, Pakistan.
