What belongs in the in-house cost column?
Include heat presses, platens, stands, electrical work, extraction or climate needs, maintenance, calibration, tools, worktables, software, training, labor, supervision, utilities, receiving, storage, quality checks, packing, and disposal. Allocate equipment over a realistic useful workload rather than dividing by an optimistic maximum. Count setup and changeover by SKU. If existing employees press during quiet periods, their time still has an opportunity cost when demand grows or other work is delayed.
What belongs in the outsourced cost column?
Use the complete finished-garment quotation: garment, decoration, artwork or setup, samples, size and color handling, packing, freight, duties where applicable, inspection, overage, shortages, replacements, and communication time. Include the cost of sending blank garments if the decorator does not supply them. Model inventory ownership and payment timing. A low unit quote may become expensive when each small replenishment carries setup and freight or when finished size inventory becomes obsolete.
Why is spoilage the swing variable?
A rejected transfer may be inexpensive, but a damaged premium garment includes garment value, transfer, labor, lost capacity, and replacement logistics. Calculate accepted-unit cost by dividing all route costs by units that pass, not units attempted. Model 1%, 3%, and 5% spoilage scenarios as sensitivity checks, then replace them with measured pilot data. The same logic applies to outsourced shortages and defects: credit notes do not always recover the cost of missing stock at a launch.
How should labor and capacity be measured?
Time a complete representative batch from receiving through packed acceptance. Capture artwork lookup, sorting, press warm-up, first-piece approval, alignment, pressing, peeling, cooling, inspection, rework, folding, packing, and cleanup. Measure good units per paid hour across several SKUs, not one simple logo. Then ask whether the press is a constraint. If internal capacity displaces profitable work or requires overtime during peaks, that opportunity cost belongs in the model.
When does a hybrid model make sense?
Keep stable high-volume or urgent replenishment in-house while outsourcing complex, seasonal, or capacity-overflow work. Another hybrid is to buy ready transfers centrally and press near demand, while sending difficult garments to a specialist. The model needs clear qualification rules so local teams do not improvise on unsupported fabrics. Compare scenarios at 100 units, 500 units, and 2,000 units per month; these are planning levels, not supplier minimums, and real break-even depends on local inputs.
How should procurement make the decision?
Collect comparable RFQs, run an in-house pilot, and use ranges for uncertain volume, spoilage, labor, and freight. Include service factors such as control, speed, traceability, intellectual property, change responsiveness, and management attention alongside cost. WowSticker can quote transfer supply and sample production, but buyers should insert their own garment, wage, facility, tax, freight, and quality data. Recalculate when volume, product mix, labor availability, or equipment utilization changes.
Decision table
| Material or substrate route | Cost or price effect | Best-fit use or application scenario | Main risk |
|---|---|---|---|
| In-house pressing | Fixed equipment and space plus variable labor and spoilage | Steady demand, trained team, qualified garments, and frequent replenishment | Hidden labor, underused equipment, inconsistent settings, and damaged garments |
| Outsourced finished garments | Quoted finished-unit cost plus freight and vendor margin | Seasonal or variable demand and limited internal capability | Minimum economics, communication delay, inventory, and less process visibility |
| Central transfers with distributed pressing | Transfer scale with local labor and equipment | Multi-site demand near end users | Operator and press variation across locations |
| Hybrid capacity model | Two supplier paths and added governance | Stable core volume with seasonal overflow or specialist items | Specifications drift between routes |
Execution steps
- Define accepted-unit scope and collect complete in-house and outsourced cost categories for the same garment and artwork.
- Run a representative internal pilot and obtain comparable supplier RFQs with samples, packing, freight, and defect terms.
- Model low, expected, and high volume, labor, spoilage, utilization, freight, and inventory scenarios.
- Add capacity, control, timing, quality, cash, and management-risk scores rather than selecting on unit price alone.
- Choose in-house, outsourced, or hybrid rules, document assumptions, and review the model after measured production.
WowSticker Practical Experience
In cost reviews, our practical recommendation is to measure a complete batch and count accepted garments at the end. Press-cycle time alone omits most labor. Record every damaged blank and repeated application. If the business chooses in-house production, keep approved job cards and samples so savings do not depend on one experienced operator's memory. If it outsources, require the same garment, artwork revision, placement, finish, packing, and inspection scope in every quotation.
Final suitability for Is It Cheaper to Press Heat Transfers In-House or Outsource Garments depends on the submitted artwork, construction, application evidence, quantity, site, and buyer procedure.

Frequently asked questions
What cost should be compared?
Compare total cost per accepted packed garment under the same specification, not transfer price versus a finished-unit quote.
Is existing labor free for the model?
No. Its time has a cost and may displace other work, even when no new employee is hired.
How should spoilage be counted?
Include garment, transfer, labor, capacity, rework, and replacement logistics, then divide total cost by accepted units.
When does outsourcing fit best?
It often fits seasonal, variable, complex, or low-frequency demand where internal equipment and skills would be underused.
Can a business use both routes?
Yes. Define which products stay in-house and which go to specialists or overflow suppliers, using one controlled specification.
How often should the model be refreshed?
Update it when volume, mix, wages, garment cost, spoilage, utilization, freight, equipment, or supplier terms materially change.
