16 units still owed
The half-received order.
A supplier ships 24 of 40. The order gets marked received to tidy the screen, and the 16 still owed only come up again when a customer asks for one.
Shopify apps · Custom development
Shopify apps for the work behind the counter.
Purchase orders, partial deliveries, late freight bills and stock counts across locations. Merchavelo builds the apps that keep those records straight, starting with Inventory. If your process needs its own app, we build that too.

The cost of doing it by hand
Where the margin quietly goes.
Three things that happen in most stores that buy from suppliers. None of them shows up on a dashboard until it has already cost money.
$150 freight, two weeks late
The bill that arrives after the stock.
The goods were costed at $20 a unit. Then the freight invoice lands. Unless someone reworks the cost, every margin report keeps using $20.
1 cost field per variant
The number nobody trusts.
Shopify stores one cost per variant across every location. Updated by hand from whatever invoice was nearest, it becomes a guess everyone builds on.
Merchavelo Inventory
One record from the purchase order to the next reorder.
Inventory follows a delivery through every step that changes what it cost or where it sits. Each step is saved with a name and a time, so “what happened here?” already has an answer.
- Partial deliveries on one purchase order
- Several invoices and late freight per order
- Product costs approved by a manager
- Counts and transfers across locations
- Reorder suggestions that show their working
- Stocky history kept as an archive

See how it worksFour rules Inventory keeps
Built so the record still holds up months later.
When a supplier disputes a delivery or your accountant asks where a cost came from, the answer should already be written down.
- 1
Stock moves when a receipt is processed.
Saving a draft or opening a purchase order never changes Shopify quantities. Accepted units reach the destination location when the receipt is processed.
- 2
Posted records stay as posted.
A correction is a new reversal or adjustment with a reason and a name. The original receipt is still there when the supplier asks about it.
- 3
A person approves every cost change.
Inventory previews the new landed unit cost. A manager approves it before Shopify’s cost field changes, and sees that the field applies at every location.
- 4
History never adds stock.
Imported Stocky records go into an archive. They feed your reports and never receive the same units a second time.

Your process doesn’t fit an app? We build one that does.
Internal tools, admin extensions and connections between Shopify and the systems you already use. Every project starts with a written scope and a price.
- A written scope and price before paid work
- Built and tested on a development store

Straight answers.
Can I install Inventory today?
Not yet. Inventory is preparing for release. Request early access and we’ll email you when it can be installed on your store.
Who is Inventory for?
Shopify retailers who buy from suppliers and stock more than one location. Purchase orders, partial deliveries, invoices and landed costs are where it does the most work.
Does it cover what we used Stocky for?
It covers purchasing, receiving, costs, stocktakes, transfers and reorder suggestions, and imports Stocky CSV history as an archive. Each workflow page lists the details and the limits.
Does it print labels?
Labels download as a PDF, and you print them on your own printer.
Do you build apps for other workflows?
Yes. We build custom Shopify apps: internal tools, admin extensions and connections to other systems. See how a project runs.
