A small sewing workshop can operate for years without management software. But no workshop can last long without knowing how much fabric it has in stock.
The problem isn't stolen fabric. The problem is that 50 meters shipped yesterday went unrecorded. It's the roll of fabric imported in March that sat in a corner until September, only to be discovered yellowed. It's the urgent order for 500 shirts, only to find out after a 2-hour inventory check that there isn't enough fabric.
This isn't a technology problem. This is a problem of information.

You're not losing fabric — you're losing information
Most small sewing workshops, when discussing inventory issues, use the phrase “losing fabric.” But in reality, fabric doesn't just disappear. It's dispatched — but no one records it. Or it's recorded incorrectly. Or recorded so late that no one remembers how much was dispatched.
A few familiar scenarios:
Scenario 1: Received an order for 800 polo shirts. Checked the ledger: 350m of white stretch fabric remaining. Enough. On cutting day, the tailor reported only 280m left — 70m had been dispatched last week for another order but wasn't recorded. Fabric shortage, order delayed by 3 days, incurred a penalty.
Scenario 2: The order requested navy blue 'kate' fabric, 'like last time.' The warehouse had 3 rolls of blue 'kate' fabric, but from 3 different import batches. The colors were slightly off-tone. After sewing, the customer discovered 200 shirts were a different color from the remaining 600. Returned the goods.
Scenario 3: During the end-of-quarter inventory check, 15 rolls of fabric were found to have been in stock for over 6 months. Total value: 45 million VND. The cotton had yellowed, the polyester had brittle edges. 45 million VND in dead capital, unnoticed by anyone.
All three scenarios share a common root cause: lack of accurate information at the right time. It's not a human error. It's a system error — or more precisely, the error of not having a system.
The hidden costs no one accounts for
When discussing losses from poor inventory management, people often think of lost fabric. But in reality, the biggest costs lie in places no one notices:
5 Hidden Costs of an Unsystematic Fabric Warehouse
- Capital Tied Up in Long-Term Stock — 15 rolls of fabric in stock for 6 months = 45 million VND not circulating. That money could have bought fabric for 2–3 new orders.
- Inventory Check Time — 2 people × 2 days per month = 4 workdays. A year is nearly 50 workdays just to recount what should have been readily known.
- Urgent Purchases at High Prices — When a fabric shortage is discovered close to the delivery date, you have to buy retail, urgently, accepting prices 10–20% higher than pre-ordered.
- Undetected Damage — Cotton fabric gets moldy, synthetic fabric gets brittle edges. If you don't know when each roll was imported, you won't know which rolls need to be dispatched first.
- Loss of Customer Trust — One late order might be an anomaly. Two or three, and you've lost a customer for good.
“The cost of not knowing what you have in stock is always greater than the cost of any management system.”
How is a fabric warehouse different from a regular warehouse?
If you've ever tried using a generic inventory management file (the kind used for stores, pharmacies, components) to manage fabric, you'll find it's missing many things. Because fabric is not a typical commodity:
| Features | Typical Inventory | Fabric warehouse |
|---|---|---|
| Units of Measure | Pieces, boxes, items | Meters, kilograms, rolls (varies by type) |
| Lot Differentiation | Not necessary | Required (color variation between dye lots) |
| Deterioration Over Time | Ít | Yellowing, mold, brittleness, shrinkage |
| Capacity | By quantity | By shelf length + weight |
A generic inventory management system won't have a “dye lot” column, won't have inventory age alerts, and won't calculate shelf capacity by meters. And these are precisely the things that cause discrepancies in your fabric inventory.
What should a fabric inventory system be able to do?
No need for complexity. A system fabric inventory management can be achieved by answering 4 key questions at any time:
How much do you have?
Current stock of each fabric code, updated instantly after every transaction (in/out). No need to manually count.
Where?
Specific shelf location of each fabric roll. Even new staff can find it immediately.
How long has it been there?
Stock age of each roll — when it was received, how long it has been stored. Prioritize shipping older stock first.
When do I need to reorder?
Automatic alerts when stock falls below minimum level — reorder proactively, avoid reactive purchasing.
If your file can answer the 4 questions above without needing to open the warehouse and count, you already have a functional system. If not — you are relying on memory, and memory is not a system.
Excel or specialized software?
Short Answer: depends on the scale of your operations.
Dedicated WMS (Warehouse Management System) software is designed for large factories: thousands of SKUs, barcode scanners, ERP integration. Fees range from 2–15 million VND/month. For a garment workshop with fewer than 30 employees and under 200 fabric codes, that's overkill.
Excel for Fabric Inventory Management linked formulas can solve 90% of a small workshop's needs: real-time inventory tracking, stock alerts, fabric age tracking, and summary reports. Cost: 0đ (if built yourself) or a one-time fee (if using a template). Share via Zalo. Anyone can open it.
Important NoteExcel is only effective when sheets are linked by formulas: enter an outbound slip → inventory automatically decreases → alert if below threshold. Disjointed spreadsheets are not a system — they're just an electronic notebook.
Start with what you have
You don't need to wait until you're 'free' to reorganize your inventory. You also don't need to buy anything extra. All it takes is one afternoon and a new convention:
- One-time Inventory Count — count each roll, record code, quantity, and location. This is the only reliable starting point.
- Enter into a file with formulas — the file needs to automatically calculate inventory when you record inbound/outbound movements. If you have to add manually, you'll give up after 2 weeks.
- A Single Convention: fabric leaves shelf = record immediately. No exceptions. No 'I'll record it later.' This is the hardest but most important habit.
- Set Alert Thresholds for each fabric code: how much to reorder, how much constitutes a full shelf.
- 15 minutes at the start of each week: check the dashboard — which codes are running low, which codes have been in stock for a long time, what needs to be ordered.
“The best system isn't the most expensive one. It's the system you actually use every day.”
Frequently Asked Questions
My workshop only has 20–30 fabric SKUs, do I need this?
Yes. Inventory discrepancies don't depend on the number of SKUs, but on whether inbound and outbound movements are recorded. Forgetting to record just one roll can throw off your entire inventory.
What if my workers don't know Excel?
Workers don't input data. The warehouse manager does. Workers only need to report the SKU code and the number of meters taken — either by writing it down or sending a Zalo message.
What about fabric from multiple suppliers or different batches?
Add columns for 'import batch' and 'supplier.' The same fabric SKU but from different dye lots needs to be tracked separately to avoid color discrepancies during sewing.
Can I use Google Sheets?
Yes, absolutely. It's highly compatible. Additional advantages include: multiple people can view simultaneously, and data is automatically saved to the cloud.
