v6.2.0 — 8 January 2026

Type: Minor release
Breaking changes: None

Highlights

Batch and lot tracking

Products can now be tracked at the batch (lot) level — essential for food, pharmaceuticals, chemicals, and any industry with traceability requirements.

How to enable per product:

1. Open the product → Stock Settings tab
2. Toggle Batch Tracking to ON
3. Save

Once enabled:

• Every stock addition requires a batch/lot number
• An optional expiry date can be entered per batch
• The Inventory table shows a batch breakdown for each product
• Sales orders can specify which batch to pick from
• Movement log records the batch number on every transaction
• Expiry report: Go to Reports → Inventory → Expiring Stock to see all batches expiring within a configurable window (e.g. next 30 days)

Unit conversions

You can now sell a product in a different unit than you purchase it.

Example: Buy in Carton of 24, sell by Piece.

Setup:

1. Open the product → click Unit Conversion
2. Set purchase unit: Carton / Quantity per unit: 24
3. Set sales unit: Piece
4. Save

When receiving a PO of 10 cartons, StockFlow adds 240 pieces. When selling 6 pieces, it deducts 6 pieces. Reports show both units depending on context.

FIFO inventory valuation

In addition to Weighted Average Cost (WAC), StockFlow now supports FIFO (First In, First Out) as a valuation method.

Set per warehouse in Settings → Warehouses → [Warehouse] → Valuation Method.

With FIFO enabled:

• The cost of goods sold is calculated using the cost of the oldest stock first
• The inventory value report shows which cost layers exist and how many units remain at each cost
• This is required for GAAP compliance in many jurisdictions

Migration note: Switching from WAC to FIFO on an existing warehouse requires a full recalculation of historical cost layers. This is done automatically when you make the change, but may take a few minutes for warehouses with large movement histories.

Improvements

• Stocktake workflow — stocktake sheets now show the last known quantity, making the count faster (previously this was hidden to avoid biasing the count; now optionally shown as a reference)
• Goods List — new Date added column (hidden by default — enable in column settings)
• Client records — added Industry custom field type to the custom fields builder
• Transfer receipts — you can now print a transfer receipt PDF when confirming a warehouse transfer
• API — batch/lot number fields added to stock movement endpoints
• Notifications — new notification type: “Batch expiring in X days” (configurable threshold)

Bug fixes

• Fixed: Creating a product with an emoji in the name caused the CSV export to fail with an encoding error
• Fixed: WAC cost price not updating correctly after a negative stock adjustment
• Fixed: Report scheduler sending duplicate emails when daylight saving time changed
• Fixed: Goods List image thumbnails not displaying for images with uppercase file extensions (.JPG, .PNG)
• Fixed: Sales orders showing “Insufficient stock” warning even when “Allow backorders” was enabled on the product
• Fixed: Searching for a client by phone number with spaces or dashes not returning results
