## How do you add a second garment factory without risking the season?

Add a second factory when you need capacity, a second product capability or risk cover, not when you are already late on a cut. Keep style ownership clear (which factory owns which SKUs), transfer quality with the same approved sample (SMS), measurement chart and AQL rules, and run parallel sampling before you promise wholesale or DTC delivery dates. Typical production lead time in Portugal is 6 to 10 weeks after sample approval, so the calendar has to include overlap, not a cold handoff.

This guide covers when dual-sourcing helps versus when it creates chaos, how to split work without confusing purchase orders, how to keep quality aligned across two factories, a season calendar, and the red flags that mean you are not ready for a second line yet.

## When should you add a second clothing factory?

Founder communities keep describing the same pressure: one factory goes quiet, bigger clients take the slot, or capacity does not match the brand's urgency. A second factory is a capacity and risk tool. It is not a substitute for a broken brief.

| Signal | Keep one factory | Add a second |
|---|---|---|
| Steady reorders, clear SMS, dates hit | Stay; deepen the relationship | Optional risk cover for peak season only |
| Capacity squeeze from their bigger clients | Negotiate a slot or staged delivery | Yes, if your styles will always sit behind others |
| New category they do not actually run (e.g. structured coats vs jersey) | Do not force them | Yes; different capability needs a different factory |
| One late reply in an otherwise clean season | Reset calendar and weekly owner | Not yet |
| You want lower unit cost by splitting every style in half | Usually no | Rarely; split adds setup and shade risk |
| Vague tech pack, no SMS, changing colourways weekly | Fix the brief first | Adding a factory recreates the same failure twice |

Dual-sourcing is different from [switching manufacturers](/hub/blog/how-to-switch-clothing-manufacturers-without-losing-quality). Switching exits one relationship. Adding a second keeps Factory A on its styles while Factory B takes new capacity or a new category. If Factory A is failing quality after a written fix, that is a switch case, not a polite dual-source story.

## How do you split styles and purchase orders across two factories?

Ambiguous POs are how seasons miss. Write ownership down before anyone cuts.

**Style ownership.** Assign each style (or colourway family) to one primary factory. Do not split the same SKU across two factories in the same drop unless you have locked shade bands and identical SMS references at both. Shade drift between lots is a classic bulk failure; see [why bulk orders do not match the sample](/hub/blog/why-your-bulk-order-doesnt-match-the-sample-and-how-to-prevent-it).

**Quantity splits.** Prefer fewer styles with enough units per factory over many micro-runs. Across factories that publish MOQ data on NovaSupplier's [low MOQ manufacturers page](/hub/manufacturers-in-portugal/low-moq) (42 of them as of 5 November 2026), the lowest published minimum is 50 units and the median of each factory's lowest minimum is 100 units. Confirm every minimum in writing for your exact style and colourway split.

**PO hygiene.** Each PO should name one factory, one Incoterm, one delivery window, deposit and balance terms, and the SMS / measurement chart revision it is cut against. Do not recycle a PO number across factories.

**Fabric and trim ownership.** Who buys fabric, who holds mill reservations, and who owns leftover rolls must be explicit. If both factories need the same fabric story, plan lot continuity or accept that colourways may diverge.

**Accounts.** Two factories means two deposit calendars. Fund both before you announce a launch date. Payment structure guidance: [how to structure payment terms with a clothing manufacturer](/hub/blog/how-to-structure-payment-terms-with-a-clothing-manufacturer).

## How do you keep quality aligned at two factories?

Quality does not travel in a PDF alone. Transfer the same artefacts to both lines.

| Artefact | Why dual-sourcing needs it | What both factories get |
|---|---|---|
| Measurement chart with tolerances | Fit drift between factories is visible on the rail | Same graded sizes and tolerance band |
| Approved SMS | Bulk must match one reference, not two moods | Physical sealed sample or a controlled duplicate |
| Construction notes | Seam types and finishes diverge quietly | The tech pack pages actually used in production |
| Fabric lot and shade notes | Two mills or two lots create two colours | Lot numbers, shade band, approved dips |
| AQL and fault list | Arguments multiply with two QC languages | Same critical / major / minor definitions |
| Packing spec | Retail and DTC refuse on pack as often as on stitch | Identical polybag, label and carton rules |

Ask each factory to confirm in writing that bulk will be inspected against the same SMS and chart. Use the [garment inspection checklist and AQL guide](/hub/blog/garment-inspection-checklist-and-aql-for-small-brands). Build the tech pack once with the [tech pack guide](/hub/blog/what-is-a-tech-pack-and-what-a-portuguese-factory-needs-in-it) so you are not maintaining two conflicting briefs.

If Factory B is new, demand a size set and a pre-production sample from bulk-intent fabric before you approve cut. A beautiful first sample is not proof the factory can repeat at 500 units; founder posts often say the first sample "lied".

## How do you run parallel sampling without missing the delivery window?

Do not finish Factory A's season, then hope Factory B is ready in two weeks. Overlap.

1. **Shortlist.** Use 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), [knitwear](/hub/manufacturers-in-portugal/knitwear) and [jackets](/hub/manufacturers-in-portugal/jackets). Pick factories that already list your product at your quantity.
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. **Sample at Factory B** while Factory A runs its current POs. Pay for samples; free-sample hunting starts the relationship badly.
4. **Approve SMS and size set** at Factory B against the same measurement chart and shade references you use at Factory A.
5. **Place the first bulk PO at Factory B** only after that lock. 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. 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 a factory goes quiet mid-onboarding, use the follow-up pattern in [what is happening when a manufacturer goes quiet](/hub/blog/your-manufacturer-went-quiet-heres-whats-actually-happening).

## Season calendar: dual-source without a cold start

Work backwards from the in-store or ship-by date.

| Stage | What must be true |
|---|---|
| T minus 16 to 20 weeks | Brief locked; Factory B shortlisted; identical RFQ sent |
| T minus 12 to 16 weeks | Factory B samples ordered; Factory A continuing current POs |
| T minus 10 to 12 weeks | Factory B SMS and size set approved against shared chart |
| T minus 6 to 10 weeks | Factory B bulk cut starts (6 to 10 week production window) |
| T minus 2 to 4 weeks | In-line / final inspection booked at both factories |
| Ship week | Separate packing lists and invoices; no mixed cartons without a plan |

Portuguese factories often run thin through August. A dual-source plan that assumes full capacity in August is how both lines slip. Start the Factory B conversation early enough that sampling is not competing with holiday shutdowns.

## What dual-sourcing will not fix

Adding a second factory will 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
- A category mismatch (forcing a jersey factory into structured coats)

If those are true, Factory B will fail the same way Factory A did. Fix the brief first.

## Dual-source checklist (copy this)

| Step | Done? | Notes |
|---|---|---|
| Decision: capacity, capability or risk cover (written) | | |
| Style ownership map: which SKU at which factory | | |
| Shared measurement chart and SMS labelled | | |
| Identical brief / RFQ sent to Factory B shortlist | | |
| Quotes compared on the same scope | | |
| Fabric and trim ownership settled for both | | |
| Parallel samples ordered and dated | | |
| Factory B SMS approved against Factory A reference | | |
| AQL and fault list agreed at both | | |
| Separate POs, deposits and delivery windows | | |
| First Factory B bulk sized conservatively | | |
| Inspection booked at both factories | | |
| Packing and labeling identical where SKUs must match | | |

## Red flags that you are not ready for a second factory

| Red flag | Why it matters |
|---|---|
| You cannot name which styles stay at Factory A | POs will collide and shade will drift |
| Factory B will not hold your SMS as the bulk reference | Dual quality languages by design |
| You plan to split every colourway 50/50 for "fairness" | Double setup, double lot risk |
| No funded deposits for both calendars | One line stalls while the other ships |
| Brief still changing weekly | Two factories amplify chaos |
| You are already inside the 6 to 10 week cut window | Sample first; do not dual-cut cold |

### When should a clothing brand add a second factory?

Add a second factory when you need more capacity, a product capability your current factory does not have, or risk cover for a peak season. Do not add one only because one shipment was late if the root cause was a thin brief or a date set inside a 6 to 10 week production window.

### Is dual-sourcing the same as switching factories?

No. Switching exits the current factory. Dual-sourcing keeps Factory A on assigned styles and brings Factory B in for capacity or a second category. Use the switch guide when quality or capability has already failed after a written fix.

### How do you stop quality drifting between two factories?

Give both the same SMS, measurement chart with tolerances, fabric lot and shade notes, construction pages and AQL rules. Confirm in writing that bulk is judged against those artefacts. Sample at Factory B before the first bulk cut.

### Should you split the same SKU across two factories?

Usually no for the same drop. Prefer clear style ownership. Splitting one SKU raises shade and construction drift unless both factories share locked references and lot notes.

### How long does it take to bring a second Portuguese factory online?

Plan sampling first, then 6 to 10 weeks of production after sample approval. Parallel sampling while Factory A finishes current POs is how you avoid a cold start.

### Can a second factory fix a bad tech pack?

No. An incomplete brief recreates the same faults at both factories. Fix measurements, construction, fabric and AQL before you shortlist.

## Post your brief and let factories come to you

If you are ready to shortlist a second factory while your first line keeps running, you can [post a brief on NovaSupplier](https://www.novasupplier.com/onboarding?intent=brand) and compare replies from factories that make your product. Factories engage with a brief in under 30 hours. It is free for brands: NovaSupplier charges brands no fee, and you pay the factory for samples and production as usual. There is no agent in between, and the factory relationship stays with your brand. NovaSupplier lists 73 active manufacturers, all in Portugal; factories pay a 3.5% commission on every order, including reorders.
