Find your bottleneck first
Almost every bad tooling decision in this category comes from buying for a bottleneck you do not have. A one-person brand buys a PLM system and gains a permissions model it will never use. A twelve-person product team keeps working in a shared spreadsheet and loses a week a season to version conflicts.
Four bottlenecks, and they arrive roughly in this order as a brand grows:
- Structure — you do not know what sections a pack needs. Cheapest to fix.
- Production — you know the structure, and drawing the flat and building the graded table takes a day per style.
- Version — several people edit, and nobody is certain which pack the factory has.
- Library — the same materials, colours and suppliers get re-entered every season, inconsistently.
1. Templates
A spreadsheet or document with the sections laid out, filled in by hand, usually paired with a separate drawing file.
- Removes
- The structure problem
- Leaves you
- All of the production work
- Fits
- First few styles, one person
- Breaks at
- Two people, or ten styles
Templates are genuinely the right answer at the start, and their weakness is specific rather than general: the drawing lives in a different file from the specification, so the two drift. The flat gets updated, the measurement table does not, and the pack goes out internally inconsistent with no mechanism that would have caught it.
The second weakness is that a template is shaped like the category it was written for. Move from apparel into plush or hardgoods and the missing rows are invisible — see tech packs by product category. If a template is where you are, the section-by-section structure is the thing to check yours against.
2. Dedicated tech pack tools
Purpose-built web applications: the sections are the data model rather than a layout, drawings and specification live in one record, and export is a single document.
- Removes
- Structure and version problems
- Leaves you
- Drawing flats, building tables
- Fits
- A small product team, many styles
- Breaks at
- Cross-season library management
This is the sweet spot for most growing brands, and the reason is version control rather than speed: one record means the flat and the table cannot disagree, and one export means the factory cannot be holding a different combination than you think.
What it does not do is fill the pack in. You are still drawing the flat, still deciding the grade rule, still typing the bill of materials. The tool has made the work reliable, not shorter.
3. PLM (product lifecycle management)
Enterprise systems where the tech pack is one artefact in a much larger model covering materials, suppliers, costing, calendars, approvals and sourcing.
- Removes
- The library problem, at scale
- Leaves you
- Implementation and process cost
- Fits
- Full-time product teams, many seasons
- Breaks at
- Small teams — it adds process
PLM is correct at the scale it is built for and expensive at every other. The value is that a material entered once is the same material everywhere, forever, with its cost and supplier attached — which is genuinely transformative when fifty styles a season share components, and pure overhead when six do.
The honest test: is your material library actually a problem yet? If you can name every fabric you use from memory, PLM will not pay for itself.
4. CAD and 3D
Pattern-making and 3D garment simulation systems, some of which can derive specification data from the digital pattern or the 3D model.
- Removes
- Fit iteration in physical samples
- Leaves you
- A real learning curve
- Fits
- Teams with pattern expertise in-house
- Breaks at
- Brands with no pattern cutter
The strength is upstream of the tech pack: if you are simulating fit before cutting cloth, you are removing sample rounds, which is the most expensive thing in the whole process. Measurements derived from a pattern are also more internally consistent than measurements typed into a table.
The cost is skill. These are professional tools that assume pattern-making knowledge, and a brand without a pattern cutter usually cannot convert them into output. They are also apparel-shaped, so they transfer poorly to categories that are not sewn garments.
5. AI tech pack generators
Tools that produce the pack from a description of the product or an uploaded design — drawing the technical flat, structuring the measurement table, populating the bill of materials, and writing the standard construction, labelling and safety copy.
- Removes
- The production bottleneck
- Leaves you
- Reviewing the specification
- Fits
- Anyone whose problem is time, not process
- Breaks at
- Anything you do not check
This is the newest of the five and the one where the claims vary most, so it is worth being precise about what moves. Producing a first complete draft is the part that compresses hardest — the flat, the table structure, the BOM skeleton, the boilerplate that is the same on every pack in a category.
What does not move is the judgement. Your size range, your fit intent, your grade rule, your material choices and your compliance obligations are decisions about your business, and a generated draft is a starting document you own, review and are accountable for. Any tool in this category that implies otherwise is describing something it cannot deliver.
The second thing worth checking is category coverage. A generator trained and built around garments will produce a garment-shaped pack for a plush toy, complete with a grading table it does not need and without the fill weight it does.
Side by side
| Approach | Structure | Production | Version | Library | Best for |
|---|---|---|---|---|---|
| Template | Yes | No | No | No | First styles, one person |
| Dedicated tool | Yes | Partly | Yes | Partly | Small product team |
| PLM | Yes | No | Yes | Yes | Full-time team, many seasons |
| CAD / 3D | Partly | Partly | No | No | In-house pattern expertise |
| AI generator | Yes | Yes | Depends | Depends | Time-constrained teams |
The two columns marked "depends" are the ones to actually test in a trial, because generators differ enormously on whether they are a document producer or a system of record.
What to check before you buy
- Does the export look like a tech pack? Ask for a real output PDF for a product like yours, and read it as if you were the factory. This single check settles most comparisons.
- Does it cover your category? Not "does it support" — does the output contain the sections your category needs, and omit the ones it does not.
- Is there a revision number on the cover? A tool that exports an unversioned document has not understood the problem.
- How does the factory receive it? A portal they will not log into is worse than an email attachment they will.
- Can you get your data out? Your specification library is the asset. If leaving means retyping, you have not bought a tool, you have rented a hostage.
- Does the measurement table carry method and tolerance columns? Both are omitted often enough to be worth checking explicitly.
Where DreamPack Studio sits
In the fifth group, and built around the production bottleneck. You describe a product — or bring your own artwork — and the pack comes back written from your design, inside your brand's approved colours and rules: the technical flat, the measurements, the materials, the labels and the safety copy.
It is not apparel-only, which is the part most relevant to the comparison above. Apparel, plush, pet, headwear, accessories and hardgoods today, and the list keeps growing — so the pack carries the sections the product actually needs rather than the sections a garment template happened to have.
Common questions
What is the best tech pack software?
There is no single best one — the five approaches solve different bottlenecks. Not knowing the structure, redrawing flats, losing versions and rebuilding the library are four different problems, and buying for one you do not have is the usual mistake.
Do I need PLM for tech packs?
Only when the library is genuinely the problem — many people, many styles, many seasons. Below a full-time product team, PLM tends to add process without removing work.
Can AI generate a tech pack?
It can produce the flat, the table structure, the bill of materials and the standard copy from a description or an uploaded design. It does not remove the judgement: your size range, fit intent, grade rule and compliance obligations remain yours to decide and to check.
Is Illustrator tech pack software?
Not on its own. It draws the technical flat, which is one of eleven sections, and it holds no graded table, no bill of materials and no revision control — so an Illustrator workflow is nearly always Illustrator plus a spreadsheet plus a naming convention.
