Oldest cost first (FIFO)
Stock you bought first is treated as the stock you sell first. A good fit for most shops, and for anything that can expire or date.
FIFO and LIFO cost tracking for Shopify.
Every delivery keeps its own cost, and every sale uses the right one. See what your stock is worth and what each sale really cost you.
Trusted by Shopify and Amazon sellers
Same product. Three prices. Which one did you sell?
You paid $10 a unit last month, $12 this month and $15 on the order that just landed. When a unit sells, its cost depends on which delivery it came from. Most stores can't answer that, so their cost of goods and stock value are a guess.
- Supplier prices change between orders, but your product shows one cost
- Month-end stock value gets rebuilt by hand in a spreadsheet
- Stock moves between locations and its cost gets lost on the way
- Returns come back at today's price, not the price they sold at
Every delivery keeps its own cost.
Channel Bay records how many units each delivery brought in and what each one cost. When you sell, it takes the cost from the right delivery, using the rule you choose.
Tee · White / M · 120 units sold
| Delivery | Units | Cost per unit | Sold from it |
|---|---|---|---|
| March | 100 | $10.00 | 1000 |
| April | 50 | $12.00 | 2040 |
| May | 80 | $15.00 | 080 |
Cost of the 120 sold$1,240
Value of the 110 left$1,560
Cost of the 120 sold$1,680
Value of the 110 left$1,120
FIFO sells all 100 March units, then 20 from April. LIFO sells all 80 May units, then 40 from April. Both add up to the $2,800 you paid.
One rule, followed everywhere.
Newest cost first (LIFO)
Stock you bought most recently is treated as the stock you sell first. A good fit when you want costs to follow today's prices.
Change your rule any time. Costs already recorded stay as they are, and the new rule applies to future sales. One rule covers every connected store.
Switch it on and keep working as usual.
The details that keep your costs honest.
Cost of every sale
Each sale draws its cost from the right delivery, so cost of goods reflects what you actually paid.
Stock value by location
Open any product to see units held at each location and what they're worth in total.
See which cost was used
Every delivery, units in, units left and cost, plus which delivery is next and which one each sale used.
Cost travels with transfers
Costs are tracked per location. Move stock to another location and its cost moves with it.
Returns at the original cost
A returned item goes back at the cost it sold at, not at today's price.
Other currencies, converted
Buy in a supplier's currency and costs convert to yours at the rate for the day the PO was opened.
Nothing slips through quietly
Stock changes Channel Bay can't explain are flagged for review, never guessed. Add a short note and the record stays clean.
Pause and keep your history
Switch Cost Tracking off and on any time. Your history stays, and you confirm what changed in between.
Export for your accountant
Download any product's cost history as a spreadsheet for finance or month-end.
Landed cost tells you what arrived. Cost tracking tells you what sold.
Purchase orders work out what each unit cost when it landed, with freight, discounts and currency spread across the lines. Cost tracking keeps those costs delivery by delivery and decides which one each sale uses.
Built for anyone who needs the real number.

Book a demoShould I choose FIFO or LIFO?
Most shops choose oldest cost first (FIFO), because stock usually sells in the order it arrives. Choose newest cost first (LIFO) if you want costs to follow today's prices. Check with your accountant for tax reporting.
Can I change my rule later?
Yes, any time. Costs already recorded stay as they are, and the new rule applies to future sales.
What happens to the stock I already have?
When you switch Cost Tracking on, your current stock is recorded at each product's current cost, so you're covered from day one.
Can I use a different rule for each store?
No. One rule applies across all your connected stores.
Do I need anything else switched on?
Yes. Cost Tracking works with Cost price sync, which keeps your product costs up to date in Shopify. Both need to be on.
