## How do you switch clothing manufacturers without losing quality?

Switch only when the current factory cannot fix a clear quality, capacity or communication failure. Exit with open purchase orders, fabrics, patterns and tech packs settled in writing, then transfer quality by locking the approved sample (SMS), measurement chart, AQL rules and fabric lot notes before the new factory cuts. Run parallel sampling at the second factory while the first finishes any last-buy, so the season does not depend on a cold start.

This guide covers when to switch versus fix, how to exit cleanly, how to transfer quality, how to sample in parallel, a handover checklist, and the red flags that switching will not fix because the brief itself is broken.

## When should you switch a clothing factory versus fix it?

Not every bad shipment means a new factory. Founder communities repeatedly describe the same quality shock: a sample set from a factory marketed as premium that had no redeemable quality in the pieces, or a bulk run that looked nothing like the sample. Those stories are real. They still do not mean every problem is a factory problem.

| Signal | Fix the current factory | Switch |
|---|---|---|
| One defective lot with a clear root cause | Yes: CAPA, rework or credit, tighter AQL next run | Only if the same fault repeats after a written fix |
| Sample good, bulk bad on the same fabric lot | Fix with locked SMS, lot continuity and in-line checks | Switch if the factory will not hold the SMS as the reference |
| Late replies and missed dates once | Reset the calendar and a single weekly owner | Switch if silence repeats across two production cycles |
| Capacity squeeze from their bigger clients | Negotiate a slot or a staged delivery | Switch if your styles will always sit behind others |
| Wrong product capability (e.g. wash or bonding) | Do not force them | Switch; they were never the right factory |
| Vague brief, missing measurements, no SMS | Fix your brief first | Switching will recreate the same failure |

A brand that left a long-term factory for better quality control was solving a repeated QC gap, not a one-off miss. That is a switch case. A brand that got one weak sample after a thin brief usually has a briefing problem first. Read [why bulk orders do not match the sample](/hub/blog/why-your-bulk-order-doesnt-match-the-sample-and-how-to-prevent-it) before you burn the relationship.

## How do you exit a clothing manufacturer cleanly?

Leave with nothing ambiguous on paper. The goal is a last clean shipment and a transferable pack, not a fight.

**Open purchase orders.** List every open PO by style, colour, quantity, price, deposit paid and remaining balance. Agree what ships, what cancels, and what credit or last-buy covers unfinished units.

**Fabrics and trims.** Who owns mill-reserved fabric, leftover rolls, and unused trims? Get lot numbers, shade references and remaining metres in writing. If you paid for fabric, arrange transfer or a buy-back. If the factory sourced it under full package, negotiate what you can take for continuity at the next factory.

**Patterns, markers and tech packs.** Confirm who owns graded patterns, markers, digital files and construction notes. Your tech pack should already be yours; if the factory developed patterns from a sketch, buy out or license the files before you leave. The [tech pack guide](/hub/blog/what-is-a-tech-pack-and-what-a-portuguese-factory-needs-in-it) lists what that pack must contain.

**Approved samples.** Gather the physical SMS (salesman sample / sealed sample), size set if you have one, and any wash or finish standards. Photograph and label them. The next factory needs the same reference, not a photo of a photo.

**Last-buy.** If you must cover sell-through or wholesale windows, place a last-buy at the current factory under the locked SMS while you sample elsewhere. Do not start a full new season at a factory you are exiting.

**Accounts.** Close invoices, deposits and claims. Keep email trails. Do not ghost the factory mid-PO; factories talk inside clusters, and a messy exit follows you.

## How do you transfer quality to the next factory?

Quality does not travel in a PDF alone. Transfer the artefacts that define "acceptable".

| Artefact | Why it matters | What to hand over |
|---|---|---|
| Measurement chart with tolerances | Fit is the first bulk failure mode | Graded sizes, critical points, tolerance band per point |
| Approved SMS | The bulk must match this, not a mood board | Physical sealed sample plus photos and labels |
| Construction notes | Seam types, stitch density, bonding, wash | Tech pack pages the old factory actually used |
| Fabric lot continuity | Shade and hand-feel shift between lots | Mill, lot number, shade band, leftover metres |
| Shade bands / lab dips | Colour approval across colourways | Approved dips and rejected examples |
| AQL and fault definitions | What fails the lot | Critical / major / minor list and AQL level |
| Packing and labeling | Retail and DTC often refuse on pack | Spec for polybags, stickers, cartons, barcodes |

Use the [garment inspection checklist and AQL guide](/hub/blog/garment-inspection-checklist-and-aql-for-small-brands) to set the same acceptance rule at the new factory that you wish you had enforced at the old one. If the first sample at the old factory "lied" (looked flawless while bulk could not repeat it), demand a size set and a pre-production sample from bulk fabric before you approve cut at the new place.

Ask the new factory to confirm in writing: "Bulk will be inspected against this SMS and this measurement chart; deviations outside tolerance are rejects under AQL [level]."

## How do you run parallel sampling with a second factory?

Do not stop production cold and hope the new factory is ready in two weeks. Overlap.

1. **Shortlist two or three factories** that already make your product at your quantity. Use published product and MOQ pages such as [manufacturers in Portugal](/hub/manufacturers-in-portugal), [low MOQ](/hub/manufacturers-in-portugal/low-moq), [T-shirts](/hub/manufacturers-in-portugal/t-shirts) and [knitwear](/hub/manufacturers-in-portugal/knitwear).
2. **Send the identical brief** (tech pack, quantities by colour, target date, Incoterm, full package or CMT). Compare replies with the [side-by-side quote template](/hub/blog/how-to-compare-factory-quotes-side-by-side).
3. **Pay for samples at the favourite one or two** while the current factory finishes any last-buy.
4. **Approve SMS and size set** at the new factory against the same measurement chart and shade references you used before.
5. **Only then** place the first bulk PO at the new factory. Keep first-run size conservative; see [how many units your first production run should be](/hub/blog/how-many-units-should-your-first-clothing-production-run-be).

Typical production lead time in Portugal is 6 to 10 weeks after sample approval. Sampling sits before that. Plan the overlap so the new factory's first bulk lands after you have a locked SMS, not after you have already promised wholesale delivery dates you cannot hit. The [clothing production timeline](/hub/blog/clothing-production-timeline-how-long-everything-actually-takes) and [samples in Portugal](/hub/blog/clothing-samples-in-portugal-timeline-cost-and-rounds) cover the stages.

If the current factory goes quiet during the exit, use the follow-up pattern in [what is happening when a manufacturer goes quiet](/hub/blog/your-manufacturer-went-quiet-heres-whats-actually-happening).

## Handover checklist (copy this)

| Step | Done? | Notes |

| Patterns, markers and tech pack files in your hands | | |
| Physical SMS and size set collected and labeled | | |
| Measurement chart and tolerances exported | | |
| Shade bands / lab dips exported | | |
| AQL and fault list agreed for the next factory | | |
| Accounts: deposits, balances, claims closed or scheduled | | |
| Identical brief sent to shortlisted factories | | |

## What switching will not fix (bad brief)

Switching factories does not fix:

- A tech pack with missing measurements, no stitch specs and no bill of materials
- No approved SMS, only a sketch or a competitor photo
- Quantity and colourway splits that change every week
- Unrealistic delivery dates against a 6 to 10 week production window
- No AQL or fault definitions, so every shipment becomes an argument
- Payment terms that the brand cannot fund (see [payment terms with a clothing manufacturer](/hub/blog/how-to-structure-payment-terms-with-a-clothing-manufacturer))

If those are true, the next factory will fail the same way. Fix the brief first. Guides on [what a factory needs before it will quote](/hub/blog/what-a-clothing-factory-needs-before-theyll-quote-you) and [finding a Portuguese manufacturer without an agent](/hub/blog/how-to-find-a-portuguese-clothing-manufacturer-without-an-agent) cover the intake side.

## Red flags that you should switch sooner

| Red flag | Why it matters |
|---|---|
| Factory refuses to hold the approved SMS as the bulk reference | Bulk will drift by design |
| Same critical fault across two lots after a written CAPA | Process is not under control |
| Will not share lot numbers or shade references | You cannot transfer colour continuity |
| Patterns and files "belong to the factory" with no buy-out path | You are locked in |
| Full prepayment demanded on every order with no inspection window | You cannot enforce quality |
| Product category they do not actually run (claimed capability only) | Samples will never become reliable bulk |

### When is the right time to switch clothing manufacturers?

Switch when a clear quality, capacity or communication failure repeats after you have tried a written fix, or when the factory lacks the product capability you need. Do not switch only because one shipment was late if the root cause was a thin brief or a date you set inside a 6 to 10 week production window.

### How do you keep quality when changing factories?

Transfer the approved SMS, measurement chart with tolerances, fabric lot and shade references, construction notes and AQL rules. Make the new factory confirm in writing that bulk will be judged against those artefacts. Run parallel sampling before you cut the first bulk.

### Should you sample at a new factory before ending the old one?

Yes. Overlap last-buy or finishing POs at the current factory with sampling at the next one. A cold cutover is how seasons miss delivery.

### Who owns patterns and tech packs when you leave a factory?

Your original tech pack is yours. Patterns the factory developed from your sketch may need a written buy-out or license. Settle that before the last PO closes so you are not locked out of your own styles.

### What is an SMS in clothing production?

SMS usually means the salesman sample or sealed sample: the approved reference garment the bulk order must match. Keep the physical piece labeled; photos alone are a weak transfer.

### Can switching factories fix a bad tech pack?

No. A incomplete brief recreates the same faults and delays at the next factory. Fix measurements, construction, fabric and AQL before you shortlist.
