  • Format: DD/MM/YYYY

Step 2c: Add Reference Number (Optional)

  • Reference Number: Your internal PO number or reference

Supplier: [Scientific Supplies Ltd ▼]
Order Date: 29/01/2025
Reference Number: PO-2025-BIO-001
Expected Delivery: 05/02/2025
Notes: Lab equipment for Spring semester

Step 3: Add Items to the Order

Two Ways to Add Items

You can add items that: 1. Already exist in inventory (link to existing items) 2. Don’t exist yet (create new items while ordering)

Method A: Adding Existing Items

When to use: Reordering items already in your inventory

  1. Click “Add Existing Item” button

  2. Search for item by name or SKU

  3. Select item from search results

  4. Fill in order details:

    Quantity:
    • How many units you’re ordering

    • Example: 10 pieces, 25.5 meters

    Unit Cost:
    • Price per unit (excluding VAT)

    • Example: £12.50 per piece

    • Currency: GBP (£)

    VAT Rate (optional):
    • Defaults to 20% (standard UK VAT)

    • Can be changed to 5% (reduced rate) or 0% (zero-rated)

    • System calculates total automatically

  5. Click “Add to Order”

Example:

Item: Laboratory Microscope (SKU: LAB-MICRO-001)
Quantity: 5 pieces
Unit Cost: £450.00
VAT Rate: 20%
---
Subtotal: £2,250.00
VAT: £450.00
Total: £2,700.00

Method B: Creating New Items While Ordering

When to use: Ordering items not yet in your inventory

  1. Click “Create New Item” button

  2. Fill in item details:

    Required Fields:
    • Name: Item description (e.g., “Pipette Tips 10-200µL”)

    • SKU: Unique stock-keeping unit (e.g., “LAB-TIPS-200”)

    • Category: Select from dropdown (e.g., “Laboratory Supplies”)

    Recommended Fields:
    • Location: Where it will be stored (e.g., “Lab Store, Shelf 3A”)

    • Unit: Measurement type (pieces, kg, meters, liters)

    • Minimum Stock: Low-stock alert threshold

    Pricing:
    • Price: Sale price (can differ from order cost)

    • VAT Included: Yes/No (affects price calculation)

  3. Fill in order details (quantity, unit cost, VAT rate)

  4. Click “Add to Order”

What Happens:
  • Item is created in inventory with initial stock of 0

  • Item added to current order

  • When order is received, stock will be updated

Important

New items start with 0 stock: Stock is only added when the order is marked as received.

Adding Multiple Items

Repeat Step 3 (Method A or B) for each item in your order:

  1. Add first item

  2. Item appears in order items list

  3. Click “Add Existing Item” or “Create New Item” again

  4. Add next item

  5. Continue until all items added

You’ll see:
  • List of all order items

  • Quantities and prices

  • Individual subtotals

  • Running order total (updates automatically)

Example Order Items List:

Items in Order:
┌────────────────────────────┬─────────┬───────────┬────────────┐
│ Item                       │ Qty     │ Unit Cost │ Total      │
├────────────────────────────┼─────────┼───────────┼────────────┤
│ Laboratory Microscope      │ 5       │ £450.00   │ £2,250.00  │
│ Pipette Tips 10-200µL      │ 10 box  │ £15.50    │ £155.00    │
│ Safety Goggles             │ 25      │ £8.00     │ £200.00    │
└────────────────────────────┴─────────┴───────────┴────────────┘

Subtotal: £2,605.00
VAT (20%): £521.00
Order Total: £3,126.00

Step 4: Handle Delivery Charges

Adding Delivery Costs

If the supplier charges for delivery:

  1. Scroll to “Delivery Charge” field

  2. Enter delivery cost (excluding VAT): £25.00

  3. System automatically: - Adds VAT to delivery charge - Distributes delivery cost across order items proportionally - Updates item costs

Why Distribute Delivery Charges?:
  • True cost per item includes delivery

  • Accurate inventory valuation

  • Better profitability calculations

Example:

BEFORE delivery charge:
- Item A: £100.00 (50% of subtotal)
- Item B: £100.00 (50% of subtotal)
- Delivery: £0.00
- Total: £200.00 + VAT

AFTER £20.00 delivery charge added:
- Item A: £110.00 (£100 + £10 allocated delivery)
- Item B: £110.00 (£100 + £10 allocated delivery)
- Delivery: £20.00 (distributed to items)
- Total: £220.00 + VAT

Note

Proportional Allocation: Delivery charge is split based on each item’s percentage of the subtotal.

Step 5: Upload Invoice PDF (Optional)

Attaching Invoice Documents

If you have the supplier’s invoice as a PDF:

  1. Scroll to “Upload Invoice” section

  2. Click “Choose File” button

  3. Select PDF from your computer

  4. File uploads automatically

Supported Formats:
  • PDF files only (.pdf)

  • Maximum size: 10MB

Benefits:
  • Keeps invoice with order for reference

  • Audit trail for accounting

  • Easy retrieval for disputes or returns

What Gets Stored:
  • Original PDF filename

  • Upload date and user

  • Link to download invoice later

Tip

Best Practice: Always upload invoices when available. Makes reconciliation and audits much easier.

Step 6: Add Order Notes (Optional)

Internal Notes

Use the “Notes” field for:

  • Special instructions (e.g., “Deliver to Lab 204, not main office”)

  • Urgency (e.g., “Urgent - needed for class on 05/02”)

  • Payment details (e.g., “Paid via university purchase card #1234”)

  • Contact person (e.g., “Contact Dr. Smith for delivery”)

Example Notes:

URGENT: Needed for Biology 101 lab on 05/02/2025
Deliver to: Chemistry Building, Lab 204
Contact: Dr. Smith (ext. 5678)
Payment: University PO #UC-2025-00123

Step 7: Review and Create Order

Final Review

Before submitting:

  1. Double-check all items: - Quantities correct? - Prices match supplier quote? - Unit costs exclude VAT (VAT added separately)?

  2. Verify totals: - Subtotal matches your calculations - VAT calculated correctly - Delivery charge (if any) is correct

  3. Confirm supplier (if selected): - Correct supplier selected - Contact details accurate

Common Scenarios and Tips

Scenario 1: Partial Deliveries

Situation: Supplier delivers some items now, rest later

Solution:
  1. Receive order with actual quantities received

  2. Add note: “Partial delivery - 2 items on backorder ETA 12/02”

  3. For backordered items: - Option A: Create new order for remaining items (recommended) - Option B: Wait and manually adjust stock when backorder arrives

Best Practice: Create a new order for backordered items with reference to original order

Scenario 2: Wrong Items Received

Situation: Supplier sent wrong item or wrong quantity

Solution:
  1. Do NOT receive the order yet

  2. Contact supplier to resolve

  3. Once corrected items arrive, then receive order with actual quantities

  4. Add notes explaining the situation

If Already Received:
  • Use stock adjustments (Inventory page) to correct

  • Add detailed notes explaining the correction

Scenario 3: Recurring Orders

Situation: You order the same items regularly (e.g., monthly lab supplies)

Tip: Use reference numbers consistently:
  • Format: “MONTHLY-LAB-JAN2025”, “MONTHLY-LAB-FEB2025”

  • Easy to find historical orders

  • Compare pricing over time

Future Feature: Order templates (coming soon - see roadmap)

Scenario 4: Emergency/Urgent Orders

Best Practice:
  1. Use reference number prefix: “URGENT-” or “PRIORITY-”

  2. Add clear notes with deadline and reason

  3. Include contact person for delivery

  4. Flag expected delivery date

Example:

Reference: URGENT-LAB-SAFETY-2025-02
Notes: URGENT - Safety equipment for inspection on 08/02
       Contact: Dr. Smith (ext. 5678) for immediate delivery

Troubleshooting

Common Issues

“Cannot find item in search”
  • Item may not exist yet

  • Check spelling and try SKU instead of name

“Delivery charge not calculating correctly”
  • Ensure delivery charge entered BEFORE reviewing totals

  • Refresh page if amount doesn’t update

  • Check that items have subtotals (prices entered)

“Cannot receive order”
  • Check you have permission (Manager or Admin role)

  • Order must be in “Pending” status

  • Already received orders cannot be re-received

“Stock didn’t update after receiving”
  • Check order status is “Received” (not “Pending”)

  • Verify received quantities were entered

  • Check stock movements (click “View Audit Trail” on item)

  • Contact admin if issue persists

“Invoice won’t upload”
  • Check file is PDF format

  • File size must be under 10MB
