What Belongs in a Tech Pack, and How PolyPM Keeps It Accurate from Sample to Bulk

What Belongs in a Tech Pack, and How PolyPM Keeps It Accurate from Sample to Bulk

Every apparel factory has watched the same thing happen. The sample fits, the buyer signs off, the order moves to bulk, and the garment coming off the line is not the garment that was approved. The tech pack is usually where the trouble started.

Most spec packages are built in a spreadsheet, exported to PDF, emailed to a factory, then revised four times before the first cut. By the time bulk runs, nobody is certain which version the sewing floor is working from. The trim supplier has one revision, the cutting room has another, and the costing sheet still shows the fabric that was swapped out in week three.

We built our fashion apparel PLM software so that stops happening. In PolyPM, the spec is not a document that gets mailed around. It is live data sitting in the same system that runs purchasing, cutting, sewing and shipping, so when a measurement changes, everything downstream changes with it.

We have been writing software for cut-and-sew manufacturers since 1986, and PolyPM has been refined on real factory floors for more than two decades. No add-ons. No workarounds.

What a Tech Pack Actually Has to Do Once It Leaves Design

A finished spec is not a design document. It is a manufacturing contract, and it has to hold up in three rooms at once.

It tells the factory what to make. Construction method, stitch type, seam allowance, trim placement, label position, finishing. If a sewing supervisor has to phone someone to ask a question, the package was incomplete before it shipped.

It tells purchasing what to buy. Every fabric, trim and consumable, with supplier, color, placement and consumption per size. Material planning runs straight off that list. Get it wrong and you either tie up cash in fabric nobody needs or stop a line waiting on 300 yards of twill.

It tells quality control what to measure. Points of measure, tolerances and grade rules. Without those, QC and the factory spend the pre-production meeting arguing about whether half an inch matters.

Those readers rarely sit in the same building. Development might be in New York, cutting in Honduras, screen printing with a subcontractor two hours from the plant. The information has to travel, stay readable in two languages, and survive a dozen revisions without anyone losing track of which one is live.

A spreadsheet cannot do that. It takes a system where the spec, the product lifecycle management record, the purchase order and the cut ticket all read from the same database.

Where Tech Packs Break Down Between Sample and Bulk

The sample stage is forgiving. One pattern maker, one sewer, one person checking the result. Bulk is not, because the number of people touching the style multiplies and every one of them works from a copy.

Version drift

Revision 4 goes to the factory on Tuesday. Revision 5 goes out Thursday with a changed pocket bag. The cutting room already printed revision 4 and taped it to the wall. Nobody did anything wrong, and 1,200 units still come out with the wrong lining.

The bill of materials and the purchase order stop agreeing

The spec is updated when a trim is substituted. The purchase order is not, because it lives in a different system. The variance surfaces at month end when somebody tries to reconcile inventory.

Measurements that were never graded properly

A sample spec covers one size. Bulk covers eight. If grade rules sit in the pattern software and the measurement chart sits in a spreadsheet, the two can disagree for a whole season before anyone notices the 2XL is running short in the sleeve.

Color approvals that live in an inbox

Lab dips and strike-offs get traded over email. Six weeks later nobody can prove which submission was approved, and the factory produces against the one they happened to keep.

Questions answered verbally

A supervisor calls the merchandiser about a topstitch. The answer is correct and never written down. The next order repeats the question and gets a different answer.

Each of these is small. Together they are why a style costs more than it was quoted at, ships late and comes back with a chargeback. Connecting style data to apparel order management and live material positions is what closes the gap.

What Belongs in a Tech Pack: The Nine Sections PolyPM Builds In

These are the components a factory needs in order to produce without asking a question. In PolyPM each one is a structured record attached to the style rather than a page in a document, which is what lets the rest of the system act on it.

1. Style header and identity

Style number, season, brand, category, size range, fit, status, developer, target cost and target delivery. Everything else hangs off this record. When the status moves to approved, the style becomes available to order entry and production planning automatically.

2. Bill of materials

Every fabric, trim, thread, label, hangtag and carton, with supplier, color, placement and consumption per size. Our BOM feeds material requirements planning, so a change to consumption recalculates what needs buying across the open order book.

3. Construction and stitch details

Seam type, stitch class, stitches per inch, seam allowance, interlining, finishing method. Our customers build libraries of standard operations and pull them into new styles instead of retyping them every season.

4. Measurement chart and grade rules

Points of measure, base size values, tolerances and the grade rule applied across the range. This is the section most often wrong, because it is usually kept separately from the pattern. In PolyPM the chart and the graded pattern design data belong to the same style.

5. Colorways and lab dips

Each colorway with its fabric and trim colors, dye lot requirements, lab dip submissions, approval dates and approvers. That history stays attached to the style, so a question in month six takes seconds instead of an afternoon in an email archive.

6. Artwork, decoration and placement

Screen print, embroidery and sublimation specifications, with placement measured from a fixed point, ink and thread colors, screen and stitch counts, and the assigned subcontractor. Decoration ruins garments after the sewing is already paid for, which is why we track it inside apparel production software.

7. Labeling, packing and care

Main label, size label, country of origin, fiber content, care symbols, folding method, polybag size, carton quantities, ratio packs and barcodes. Retail compliance failures are expensive and nearly always come from treating this section as an afterthought.

8. Costing

Material cost from the BOM, labor by operation, decoration, freight, duty and overhead, rolled into a target and an actual. Because our costing pulls from live material prices, the quoted cost and the manufactured cost stay in the same conversation.

9. Sample history and vendor comments

Proto, fit, PP and TOP samples, what was corrected at each round, who signed off and when. Most teams skip this, and it is the section that prevents repeating last season’s mistakes.

All nine connect to live stock through our apparel inventory management software, so a specified fabric is not a line of text. It is a roll with a location and an available quantity.

How PolyPM Keeps Every Tech Pack Accurate from Sample to Bulk

Here is what happens in our system when a style moves from first proto to bulk shipment.

Step 1: One style record, and no copies. There is no file to email. Product development, sourcing, the cutting room, the decoration subcontractor and finance all open the same record. A supervisor in San Pedro Sula sees the revision a merchandiser in Los Angeles is looking at, in Spanish if that is the language they work in.

Step 2: Every change is versioned, attributed and dated. PolyPM records who changed a measurement or swapped a trim, when, and what the previous value was. That answers the question every manufacturer eventually faces in a chargeback dispute: what was approved, by whom, on what date.

Step 3: The BOM drives purchasing. Consumption figures feed material requirements planning. Change a fabric width or yield and our system recalculates requirements against the open order book, nets them against stock at roll level, and shows the shortage before the cut date.

Step 4: Measurements and patterns stay bound together. Grade rules and the measurement chart are not kept in two places by two people. Correct the pattern after a fit session and the chart the factory measures against is corrected with it.

Step 5: The spec travels with the cut ticket. Cut plans, bundles and work in progress are generated from the approved style, not retyped. Operators scan bundles through each operation, so apparel production software systems and the spec stay in agreement all the way to packing.

Step 6: Costing moves when the spec moves. Material prices, standard operation times and decoration charges roll into the costed style. Change the interlining in week two and the margin impact shows immediately, which is what makes the numbers in apparel management software trustworthy.

What Makes PolyPM Different from a Generic ERP with a PLM Module

Most platforms sold to apparel manufacturers started somewhere else. They were built for discrete manufacturing or general business management, and apparel was added later through a module or a consultant’s customization. That history shows up in four places.

A style is not a SKU. An apparel style is a matrix of colors and sizes sharing one spec, one pattern and one BOM, with consumption that varies by size. Systems not designed for that end up with thousands of item records and a spec belonging to none of them.

The spec becomes an attachment. In most adapted platforms the tech pack is a PDF stored against the item. Nothing in the system can read it, so the BOM is keyed in again for purchasing and a third time for costing.

Apparel inventory is missing. Fabric is bought by the yard and consumed by the roll, with width, shade and dye lot mattering on every one. Cut goods move in bundles. Without roll-level and bundle tracking, nothing reconciles what the floor used against what the spec said.

Nothing connects to pattern data. Marker efficiency and fabric utilization are where apparel margin is won or lost, and a generic ERP has no concept of either.

We have never had to adapt PolyPM to apparel, because it has never done anything else. Teams comparing us usually work through which ERP has the best features for apparel efficiency before a detailed comparison such as PolyPM vs Oracle Cloud ERP. The same contrast applies to NetSuite, BlueCherry, ApparelMagic, Odoo, Microsoft Dynamics GP and Acumatica.

How PolyNest Ties Pattern and Marker Data to the PolyPM Spec

A measurement chart is only as good as the pattern behind it. PolyNest is our pattern design system, handling pattern creation, grading, marker making and nesting for the same styles PolyPM manages.

That changes two things. Grade rules applied in PolyNest are the rules the measurement chart reflects, so a fit correction on the base size updates the graded range and the chart the factory measures against. And marker efficiency gives you actual yield per size and fabric width, which feeds the BOM instead of a padded guess carried over from a similar style two seasons ago.

A point or two of marker efficiency on a long program is usually worth more than every other saving on the costing sheet combined, which is why fabric utilization sits so high in any honest look at textile production software cost.

PolyNest imports DXF, drives automatic cutters and plotters, and has been in apparel plants since 1986. Patterns, markers and the tech pack describe the same garment, so they belong in the same place.

Industries PolyPM Builds Specs For

Every tech pack covers the same nine sections, but what sits inside them changes by industry, and so does what our customers configure in PolyPM.

Apparel manufacturing and garment manufacturing. Heavy BOMs, multiple colorways per style, decoration on a large share of orders, and subcontracted operations that need the same spec the main plant is working from.

Fashion manufacturing. Short seasons and constant revision. The value here is version control and sample history, because the same style gets reworked four times before it is approved and fashion calendars do not wait.

Uniform manufacturing. Specs that have to repeat exactly for years, across reorders, size runs and contract renewals. Teams running uniform manufacturing software care less about speed of development and more about an identical garment in year four.

Workwear manufacturing and safetywear manufacturing. Compliance belongs in the spec, not alongside it. Flame-resistant fabric certifications, reflective tape placement, thread type and standards references all need to be traceable to the shipped unit, which is the problem most workwear ERP buyers are actually trying to solve.

Textile manufacturing. Mills supplying cut-and-sew plants need shade, width, roll and dye lot carried through the same records their customers specify against.

Where PolyPM Supports Manufacturers

We are headquartered in Baltimore, Maryland, and we support apparel manufacturers across the United States, Canada and Latin America.

That footprint matters for spec accuracy. A large share of North American apparel production runs across a border, with development in Los Angeles, New York, Miami or Toronto and sewing in Mexico, Guatemala, Honduras, El Salvador or Nicaragua. The tech pack has to be understood identically in both places, by people working in different languages on different shifts.

Discovery calls, demonstrations, implementation and support are all available in English and Spanish. When a plant manager in Managua and a product development lead in Miami open the same style record, each reads it in their own language, with no translation step where meaning gets lost.

→ Running development in one country and production in another? Ask PolyPM how our customers keep both sides working from the same approved style.

Other PolyPM Services That Keep the Spec Honest

The spec is one record in a larger system. These are the parts of PolyPM that act on it.

Apparel Manufacturing ERP. Order management, purchasing, production scheduling, MRP, costing, shipping, vendor management and financials, all running off the approved style data.

Fashion Apparel PLM. Style management, line planning, BOMs, colorways, measurements, lab dips, artwork and sample management. This is where the spec is created and controlled.

Inventory and Materials Management. Roll-level fabric tracking, trim management, warehouse locations, shortage alerts, reconciliation and finished goods.

Production and Order Management. Cut planning, bundle tracking, work in progress, shop floor visibility, subcontractor management and decoration.

PolyNest Pattern Design. Pattern creation, grading, marker making, nesting optimization, DXF import and cutter and plotter integration.

Most manufacturers start with whichever of these hurts most, then implement more, because the value compounds once data stops being retyped between systems.

Tech Pack Accuracy with PolyPM

A complete spec covers style identity, bill of materials, construction, measurements and grading, colorways and lab dips, decoration, packaging, costing and sample history. Getting all nine right in a document is hard. Keeping them right through eight revisions, three factories and two languages is harder, and that is the part spreadsheets have never solved.

PolyPM holds every one of those sections as live data inside the system that also runs purchasing, cutting, sewing and shipping. Nothing is retyped, nothing drifts, and the garment that ships is the garment that was approved.

PolyPM and Tech Packs: FAQs

What does PolyPM include in a tech pack?

PolyPM holds style identity, bill of materials, construction details, measurement charts with grade rules, colorways and lab dip approvals, decoration placement, labeling, costing and sample history. Each is a structured record attached to the style, so purchasing, production and costing act on it without re-entry.

How does PolyPM stop a factory from working off an outdated spec?

There is no copy to go out of date. Everyone opens the same style record, and every change is versioned with the user, the date and the previous value. Months later, our customers can still show which revision was approved and by whom.

Can PolyPM connect the bill of materials to purchasing and inventory?

Yes, and that is the main reason manufacturers move to us. Consumption in the BOM feeds material requirements planning, which nets demand against stock at roll level and raises shortages before the cut date rather than after it.

How does PolyPM handle measurements and grading across a full size range?

The chart and the grade rules belong to the same style record and stay aligned with the graded pattern in PolyNest. A fit correction on the base size flows through the range, which removes the usual cause of fit failures in extended sizes.

Does PolyPM track lab dips and color approvals?

It does. Submissions, strike-offs and bulk approvals are recorded against the colorway with dates and approvers, so the trail stays on the style instead of in somebody’s email. Dye lot and shade information carries through to inventory.

How does PolyPM manage decoration specs such as screen printing and embroidery?

Decoration is a production operation in PolyPM, not an attachment. Placement measurements, ink and thread colors, screen and stitch counts and the assigned subcontractor sit on the style, and the work is scheduled and tracked like any other operation.

Can PolyPM replace both our PLM and our ERP?

That is how PolyPM is built. Product development and manufacturing run on one database, so an approved style reaches order entry, planning and purchasing with no integration between two vendors to maintain.

How long does it take to get our existing specs into PolyPM?

It depends on how your current data is held, and we scope that during the discovery call. Styles usually come across in structured imports, with construction details built into reusable libraries during implementation, so the next tech pack starts from something rather than nothing.
