How to Organize Your Warehouse in the Trades: Efficient Storage + Digital Tools [2025]

Wasting 2.5 Hours a Week?

Do you know the feeling? An urgent job is waiting, but the necessary material is nowhere to be found. 20 minutes of searching, annoyed customers, deadline pressure. According to IHK studies, craft businesses lose an average of 2-3 hours per week due to inefficient warehousing – that's over 120 hours a year.

This is what it costs you specifically:

• Lost working time: approx. €6,000 per year (at €50/hour)
• Duplicate orders due to lack of overview
• Delayed projects and dissatisfied customers
• Increased risk of accidents due to chaotic storage areas

The good news: With a structured warehouse system and the right digital tools, you not only save time but also increase your productivity by up to 30%.

In this guide, we will show you:

1. How to structure your warehouse in 3 steps
2. Which digital tools are worthwhile for small and medium-sized businesses
3. Field-tested methods from successful craft businesses
4. Concrete costs and expected time savings

Why Structured Warehousing is Essential in the Trades

A professionally organized warehouse is not a luxury; it is the foundation for profitable work. The BG BAU emphasizes in its guidelines that clearly structured storage areas not only increase efficiency but also meet legal requirements for occupational safety.

An organized warehouse solves these 5 problems:

1. Reduce time loss: No more endless searches –> every part has its fixed place
2. Lower costs: Avoid duplicate orders and expired materials
3. Improve project planning: Reliable overview of available materials
4. Increase work safety: Clear walkways, safe stacking, no tripping hazards
5. Leave a more professional impression: Also on customers who visit your workshop

Typical Challenges in Craft Businesses

Small and medium-sized businesses often struggle with:

• Limited storage space with a high variety of materials
• Spontaneous temporary storage on the floor or in corners
• Lack of clear responsibilities ("Everyone puts things away somewhere")
• Confusing duplicate stocks
• No transparency about consumption and minimum quantities

Result: Chaos, frustration, and wasted resources.

The 3 Pillars of Successful Warehouse Organization

A functioning warehouse system is based on three fundamental principles:

1. Clear Spatial Structure

• Define fixed areas for different material groups

2. Uniform Labeling

• Every employee must be able to see at a glance what is where

3. Digital Inventory Management

• Transparency about quantities, consumption, and reorder points

Step-by-Step: How to Organize Your Warehouse in 3 Phases

Phase 1: Inventory and Decluttering (1-2 days)

What you need to do:

1. Conduct a complete inventory
   • Gather all materials from shelves, corners, and temporary storage
   • Sort out damaged, outdated, or duplicate parts
   • Identify remnants and slow-moving items
2. Categorize materials
   • By trade (electrical, plumbing, building materials, etc.)
   • By frequency of use (daily, weekly, rarely)
   • By physical properties (size, weight, storage conditions)
3. Create a consumption analysis
   • Which materials are needed most frequently?
   • Which parts tie up capital unnecessarily?
   • Where do bottlenecks regularly occur?

Practical Tip: Use this moment for an inventory check and reconcile your bookkeeping. This saves double work later.

Phase 2: Define and Set Up Warehouse Zones (2-5 days)

Dividing Warehouse Zones Sensibly

A well-thought-out zoning system is the core of your warehouse organization:

Zone A – High-Frequency Area (Fast Movers):

• Consumables for daily jobs
• Place at grip height and near the door
• Examples: screws, cables, seals, pipes

Zone B – Medium-Frequency Area:

• Materials needed weekly or monthly
• Further inside the warehouse, but easily accessible
• Examples: special tools, seasonal items

Zone C – Slow Movers:

• Rarely needed spare parts and special items
• Can be stored higher up or further back
• Examples: spare parts for machines, custom-made items

Additional Areas:

• Goods Receipt Zone: For receiving and checking new deliveries
• Picking Area: for assembling orders
• Return/Repair Corner: For defective or returning parts
• Tool and Machine Area: Separate zone for expensive equipment

Route Optimization with ABC Analysis

The Goal: Minimal walking distances for maximum productivity

Application Rule:
• A-items (frequent): Grip height (80-160 cm), closest to the workshop
• B-items (medium): Middle shelf levels, central position
• C-items (rare): Upper/lower levels, peripheral areas

Heavy materials: Always store at the bottom (below 60 cm height) Hazardous materials: Separate, lockable area with a drip pan

Selecting Shelving Systems and Storage Technology

Rule of thumb for small parts:

• Drawer systems or open-fronted storage bins
• Transparent containers allow for quick visual checks
• Stackable boxes with label holders

For larger parts:

• Heavy-duty shelves with adjustable shelves
• Pallet racks for building materials
• Hanging systems for pipes and moldings

Practical Material List:

• Heavy-duty shelves (from €150/piece)
• Stacking boxes of various sizes (from €3/piece)
• Drawer cabinets (from €200)
• Open-fronted storage bins with wall mounting (from €50 for a set)
• Label printer or labeling device (from €30)

Phase 3: Implement Labeling System (1 day)

Which Labeling System Suits You?

Level 1 – Basic (for small businesses):

• Simple labels with material description
• Color coding by trade (e.g., Blue = Plumbing, Yellow = Electrical)
• Cost: approx. €50-100

Level 2 – Advanced:

• Numbering system with storage location coding (e.g., R3-F2-P15 = Rack 3, Shelf 2, Position 15)
• Labels for your items
• Cost: approx. €200-400

Level 3 – Digital (recommended):

• Barcodes linked to warehouse management or inventory software
• Mobile app for scanning and booking
• Automatic stock updates
• Cost: approx. €500-1,500 (incl. software)

Digital Warehouse Management: Software and Apps for Craft Businesses

The IHK Nord Westfalen recommends digital systems in its guide to materials management for more transparency and traceability.

Why Digital Warehouse Management?

8 concrete advantages:

1. Real-time stock overview: Always know what is where
2. Automatic reorder levels: Warning of bottlenecks before parts run out
3. Traceable transactions: Who took what and when?
4. Order-related material allocation: Assign costs directly to the project
5. Reduced stockouts: Fewer emergency purchases at higher prices
6. Simplified inventory: Via scanner instead of handwritten lists
7. Mobile access: Viewable even from the construction site vehicle
8. Supplier integration: Direct ordering from the software

Software Comparison: These Tools are Suitable for Craft Businesses

IMPORTANT NOTE: Many warehouse management systems are oversized for small craft businesses. They require extensive setup, training, and offer dozens of functions you will never use. For most small to medium-sized craft businesses, simple, focused solutions are completely sufficient.

Selection criteria:

• Company size and number of users
• Budget (one-time vs. monthly costs)
• Necessary interfaces (accounting, ERP)
• Mobile use required?
• Cloud vs. local installation

Cloud or local installation?

Cloud solution (recommended for most):

Pro:

• No own IT infrastructure needed
• Usable from anywhere (construction site, office, home)
• Automatic updates and backups
• Lower entry costs

Con:

• Dependence on the internet provider
• Monthly costs

Local installation:

• Full data control
• No dependence on the internet
• One-time license costs possible

Con:

• Own server or PC required
• Organize maintenance and updates yourself
• Not usable on mobile

FIFO Principle and Minimum Stock Levels: How to Avoid Bottlenecks

What does FIFO mean?

FIFO = First In, First Out

The principle: Older stock is used before newer stock. Especially important for:

• Materials with an expiration date (sealants, adhesives)
• Seasonal items
• Wear parts

How to implement FIFO:

1. Always store new goods at the back
2. Always take from the front
3. Note the date on packaging
4. Regularly check for expired materials

Establish Training, Responsibilities, and Processes

Why Clear Responsibilities are Crucial

The best warehouse system fails without lived processes. Common mistakes:

• "Everyone does it differently"
• No one feels responsible
• Transactions are forgotten
• Orderliness deteriorates after a few weeks

How to Successfully Introduce it to the Team

Step 1: Appoint a Warehouse Manager

• Define one person as the main responsible person
• Clear tasks: reordering, order, inventories
• Plan a time budget (e.g., 3 hours/week)

Step 2: Conduct Team Training

• A joint tour of the new system
• Practical exercises: material withdrawal, booking, returns
• Document rules in writing (hang a checklist in the warehouse)

Step 3: Document Processes

Example Process Checklist "Material Withdrawal":

1. Withdraw material
2. Enter quantity into the system, via scan or app
3. Assign order number
4. Place the container back in the correct spot

Regular Checks and Inventories

Daily 5-Minute Check:

• A quick tour
• Are walkways clear?
• Are parts in the right place?

Weekly Check:

• Reorders triggered?
• New deliveries put away?
• Returns sorted?

Quarterly Inventory:

• Complete stocktaking
• Comparison of digital vs. physical
• Sort out outdated parts
• Adjust the system if necessary

Annual General Inventory:

• Complete revision
• Cost-benefit analysis
• Identify optimization potentials

FAQ: The Most Frequently Asked Questions about Warehouse Organization

How long does it take to set up a new warehouse system?

The duration depends on the size of the warehouse and the variety of materials. For a business with 5 employees, you should plan for 5-10 working days: 1-2 days for inventory, 2-3 days for setup, 1-2 days for data entry into the software, and 1 day for team training. However, the time invested pays for itself within a few months through efficiency gains.

Is digital warehouse management worthwhile even for small businesses?

Absolutely! Even businesses with 2-3 employees benefit from simple, mobile solutions. Free or inexpensive apps (from a few €/month) already offer basic functions like stock overview, reorder levels, or even automatic reordering. The time savings usually exceed the costs in the first month.

Which materials should I sort first?

Start with consumables and fast-movers, i.e., the materials you use daily or weekly. These are typically 20% of your items but account for 80% of warehouse movements. This is where the efficiency gain is greatest.

How often should I do inventory?

An annual inventory is legally required. However, for efficient warehouse management, we recommend: a full inventory once a year, a sample inventory quarterly, and continuous monitoring of A-items monthly. With digital systems, this is much faster.

What does a complete warehouse system cost?

For a small craft business (3-5 employees), expect an initial investment of €3,000-€5,000 (shelves, containers, software, labor). Larger businesses (10+ employees) invest €8,000-€15,000. The payback period is typically 4-8 months through time and cost savings.

How do I motivate my team for the new order?

Clearly communicate the benefits: less search time = more time for real work, less stress, more satisfied customers. Involve the team in the planning ("What bothers you the most?"). Celebrate small successes. Consider incentives like a team bonus for successful implementation.

Which software is the best for craft businesses?

That depends entirely on your needs and the complexity of your requirements and cannot be answered universally. The simpler the software, the more likely your team is to use the new tool. Make sure that working with it is enjoyable for your team. Nobody wants to attend a training course just to operate a warehouse app.

Can I also organize my warehouse with Excel?

Yes, Excel works for a start. But: Excel is not mobile-friendly, prone to errors with multiple users, offers no automatic warnings or orders, and is time-consuming. For long-term success, we recommend switching to a dedicated solution after 6 months at the latest.

What do I do with materials I only need once or twice a year?

Check if storing them is worthwhile at all. It is often more economical to order such materials on demand (just-in-time). If you do store them: separate C-zone, higher shelves, annual check for usability.

How do I handle hazardous materials in the warehouse?

Hazardous materials (paints, lacquers, solvents, chemicals) must be stored separately in lockable, labeled cabinets. Observe TRGS 510 (Storage of hazardous substances). Drip pans are mandatory. Document safety data sheets digitally.

Is a barcode scanner worth it, or is a smartphone sufficient?

A smartphone is perfectly sufficient for barcodes and QR codes. Modern warehouse apps have integrated scanners. A separate barcode scanner is usually no longer needed.

How do I prevent the system from deteriorating again after a few weeks?

1. Define clear responsibilities
2. Weekly 5-minute checks
3. Consistency: Whoever doesn't put things away gets a reminder
4. Positive reinforcement: Praise for good order
5. Regular team meetings with feedback rounds
6. The system must become a routine.

Are there subsidies for digitization in the warehouse?

Yes! Many German federal states offer digitization subsidies for craft businesses. Check with your local Chamber of Crafts about programs like "Digital Jetzt" (BMWK), "go-digital," or regional funding programs. Often, 50-70% of the costs are covered.

What is the biggest mistake in warehouse organization?

The biggest mistake is starting too complex. Many businesses plan overly detailed systems that are then not followed. Our advice: Start simple, with clear zones and basic functions. Optimize step-by-step based on experience. Perfection is the enemy of "good enough."

Legal Requirements for Warehousing in the Trades

Occupational Safety and Legal Regulations

The BG BAU provides clear guidelines:

Employer's duties:

• Walkways must be at least 1 m wide and clear
• Shelves must be stable and load-bearing (labeling of maximum load)
• Store heavy loads below 60 cm height
• Regular inspection of shelves (document annually)
• Adequate lighting (at least 200 lux)
• Escape routes must not be blocked

Hazardous material storage (TRGS 510):

• Separate, lockable areas
• Drip pans for liquids
• Labeling with hazard symbols
• Keep safety data sheets accessible
• Observe maximum permissible quantities

Documentation obligations:

• Inventory lists for hazardous materials
• Inspection reports for shelves
• Proof of instruction for employees

Conclusion: Your Path to an Efficient Warehouse System

A professionally organized warehouse is not a waste of time, but an investment that pays for itself within a few months. The combination of:

✓ Clear spatial structure (zones, ABC logic) ✓ Uniform labeling (QR codes, labels) ✓ Digital inventory management (mobile apps, real-time data) ✓ Lived processes (responsibilities, training)

...reduces search times by up to 80%, saves several thousand euros per year, and increases the satisfaction of both the team and customers.

Your next steps:

1. This week: Conduct a current state analysis, measure time loss
2. Next week: Set a budget, test software
3. Within a month: Take inventory and set up the first zone
4. After 3 months: The complete system is established, measure initial successes

The effort is worth it! Craft businesses that have structured their warehouses consistently report less stress, higher productivity, and better planning capabilities.
