Pier
Alternative to Zoho Inventory
Also replaces Cin7, Katana
Stock, reservations and wholesale orders for small wholesalers.

Pier is stock and wholesale-order software for small finished-goods wholesalers who buy goods and sell to known business customers. It answers what can be promised, what must be bought and why a physical count differs from the record, without an ERP project. It is free, MIT-licensed and open source.
What it does
- Define items with barcodes, units and pack sizes, and warehouse bins
- Keep supplier terms such as price, minimum order and lead time
- Take sales orders and reserve stock, showing backorders for unmet demand
- Draft and approve supplier purchase orders
- Receive purchases in part into named bins
- Transfer stock between locations through a transit location
- Dispatch part of an order and handle returns through quarantine
- Reconcile physical counts, trace any balance, and import opening stock from its own CSV format
What it promises
- A new installation starts empty; you enter or review your real data.
- Stock changes are only ever added as movements; corrections are linked compensating movements, never edits.
- Available stock is sellable stock minus reservations; quarantine, transit and expected receipts are never sellable.
- Pier never reserves the same unit twice or allows negative sellable stock.
- An approval names the exact quantities, supplier, price and promise date, and a change makes it unusable until approved again.
- Retrying a command returns its original result instead of doing it twice.
- A returned item goes to quarantine and becomes sellable only after a separately reviewed restock.
- If stock moves after a count is taken, the old count cannot overwrite it.
- The whole installation can be exported and restored into a fresh one without posting opening stock twice.
Move in from
- Pier's own CSV format (no other tool's export is supported yet)
