Apparel production runs on documentation. Before a single piece of fabric is cut, every detail of a garment must be defined, approved, and communicated.
The tech pack carries those details. It tells the production team what materials to use, how the garment is constructed, what measurements apply, and what quality standards must be met.
The Bill of Materials, or BOM, lists every component needed to produce one unit. Fabric, lining, thread, buttons, labels, packaging all of it is captured in the BOM.
When tech packs and BOMs are managed well, production runs smoothly. When they are not, the consequences spread across the entire supply chain. Wrong materials get ordered. Production teams work from outdated specifications. Rework eats into margins. Deliveries are delayed.
At Accelon Technologies, we built FashionNX to address this problem directly. FashionNX is an ERP for textile manufacturers built on SAP Business One. It brings tech pack creation and BOM management into a single, structured system. This blog explains how it works and why it matters for apparel brands.
Why Tech Pack and BOM Management Is a Critical Challenge in Apparel
The apparel industry has unique documentation demands. A single style can exist in multiple colours, multiple sizes, and multiple fabric compositions. Each variation may have a slightly different BOM. Managing this manually creates compounding risk at every stage of production.
Tech Packs Exist in Scattered Formats
In many apparel businesses, tech packs live across email chains, shared drives, and spreadsheets. Different team members hold different versions. Production teams are not always sure which version is current.
When a buyer makes a last-minute specification change, the update must reach the production team, the sourcing team, and the quality team simultaneously. If it reaches some but not others, the result is a product that does not match what was sold.
BOMs Are Rebuilt for Every New Style
Without a structured system, teams often recreate BOMs from scratch for each new style. This is time-consuming and introduces errors. A team member may reference an older style’s BOM and carry across incorrect quantities or wrong material codes.
In ERP for textile manufacturers, BOM accuracy directly affects procurement. A BOM with incorrect quantities leads to either material shortages that stop production or excess purchases that inflate costs.
Size and Colour Variants Multiply Complexity
An apparel style available in four colours and six sizes generates twenty-four variants. Each variant may need its own BOM if fabric shades, trim colours, or construction details differ by size or colour.
Managing twenty-four BOMs manually for a single style, multiplied across an entire season’s range, is not sustainable. Errors become inevitable as the range grows.
Procurement Cannot Plan Without Accurate BOMs
Sourcing teams depend on BOM data to calculate material requirements. If the BOM is incomplete, estimated, or still in draft, procurement acts on guesswork.
The cost of this shows up in last-minute material purchases at higher prices, production delays waiting for materials that were not ordered on time, and inventory build-up from over-purchasing against inflated estimates.
Quality Control Lacks a Reference Standard
Quality teams need a clear specification to inspect against. If the tech pack is not formally documented and version-controlled, inspectors work from memory or informal notes. Defects that should have been caught in production reach finished goods stage.
What FashionNX Brings to Tech Pack and BOM Management
FashionNX is built natively on SAP Business One. Every style, every tech pack, and every BOM created within FashionNX connects directly to procurement, production, and costing in the same system.
Structured Tech Pack Creation Within the ERP
FashionNX provides a structured template for creating tech packs within SAP Business One. Every garment detail is captured in defined fields. Construction notes, measurement charts, stitch specifications, trims, labels, and quality standards all sit in one record.
There is no separate spreadsheet or design software file to maintain alongside the ERP. The tech pack lives in the system where production orders, material purchases, and costing also live.
When a specification changes, the update is made in one place. Every team member accessing the tech pack sees the current version. There is no risk of production running against an outdated spec.
Variant-Level BOM Management
FashionNX supports BOM creation at the variant level. A master style can have a base BOM. Each size or colour variant can carry its own adjustments without requiring a completely separate BOM to be built from scratch.
Size-wise fabric consumption is calculated within the BOM. Trim and accessory quantities are defined per unit. Colour-specific materials are linked to the relevant colour variant. The system manages the complexity without the team having to track it manually.
BOM Version Control
FashionNX maintains a version history for every BOM. When a BOM is updated, the previous version is retained. Production orders reference the BOM version that was active at the time the order was placed.
This means that a change made to accommodate a new season does not affect production orders already in progress. The version control provides a clear audit trail for both internal review and buyer audits.
Material Requirement Calculation From BOM
Once a BOM is finalised and a production order is raised, FashionNX calculates the total material requirement automatically. Fabric quantities, trim quantities, and accessory quantities are computed based on the BOM and the order quantity.
This calculation feeds directly into the procurement process within SAP Business One. Purchase orders are raised against actual, system-calculated requirements rather than manually estimated figures.
Cost Sheet Generation From BOM Data
FashionNX uses BOM data to generate cost sheets for each style. Material costs, processing costs, and overhead allocations are calculated within the system. This gives brands a clear view of the cost of production before an order is confirmed.
Cost sheets linked to the BOM update automatically when material prices change. The impact of a fabric price increase on a style’s cost is visible immediately, allowing the commercial team to respond before it affects margin.
Integration With Production and Quality
Tech packs in FashionNX are directly referenced in production orders. The production team works from system-generated work orders that carry the relevant specifications from the tech pack.
Quality inspection checklists are derived from the tech pack’s quality parameters. Inspectors follow a structured checklist rather than working from informal notes. Inspection results are recorded within the system and linked to the relevant production batch.
Benefits for Apparel Brands Using FashionNX as Their ERP for Textile Manufacturers
Brands that implement FashionNX for tech pack and BOM management see improvements across the production cycle.
- Specification errors at the production stage decrease because all teams work from the same system-held tech pack.
- BOM accuracy improves because variant-level management replaces manual spreadsheet tracking.
- Material procurement is better aligned to actual requirements, reducing both shortages and excess purchases.
- Cost visibility improves because cost sheets are generated from live BOM data, not manually estimated.
- Time spent rebuilding BOMs for new styles reduces significantly when base BOMs can be copied and adjusted.
- Quality consistency improves because inspection checklists are derived from the formal tech pack rather than informal references.
- Version control ensures that production teams always work against the correct, current specification.
- Buyer and audit readiness improves because tech packs, BOMs, and production records are maintained within a traceable ERP system.
Why Apparel Brands Choose FashionNX Over Generic ERP Tools
Generic ERP systems are not built for the way apparel businesses operate. They handle financials well. They manage inventory adequately. But they do not understand the relationship between a style, its variants, the tech pack that defines it, and the BOM that drives its production.
FashionNX is built specifically for the apparel and textile industry. The data structures, the workflows, and the terminology inside the system reflect how apparel businesses actually work.
A style is not just an item code. It is a combination of a design, a construction method, a set of materials, a size range, and a colour range. FashionNX represents this accurately. Every downstream process, from procurement to costing to production to quality, is built around this structure.
This is what separates a purpose-built ERP for textile manufacturers from a generic system adapted for apparel use.
