Inventory management

Inventory management software that's always right.

Tremo keeps your inventory live across all warehouses, locations and channels. Free stock, reservations, incoming inventory and replenishment advice in one view — no import batches, no manual corrections.

Free up to 100 orders a month · No credit card · Your data, exportable

Three balances, one number
Gross
What's physically there
Per location, per warehouse
− Reserved
What's already sold
Pending orders + picks
+ Incoming
What's on its way
Confirmed POs

What your shop shows as 'in stock' is always the right number here — gross, reservations and incoming inventory are all three visible.

Four symptoms of bad inventory management

If one of these patterns sounds familiar, you're structurally lagging behind on the numbers. Not tomorrow, today.

#01
Spreadsheet counts are already stale by 5 PM

Real-time mutations on every pick, receive and correction. The screen you have open now is correct to the second — across staff and warehouses.

#02
Out-of-stock on your shop during every peak

Reservations and free stock are tracked separately. What your shop shows is what's actually available — not gross stock minus a recount.

#03
Purchasing too late, or too much

Replenishment advice computes per-SKU daily velocity, stock-out days and per-supplier advice. With rules, a PO rolls out automatically when the buffer tips.

#04
Stocktaking eats a whole Saturday

Cycle counts via scan: count a location, scan the SKU, the variance is booked and logged instantly. No more annual downtime.

What it solves

Inventory management isn't just 'getting numbers right'. It's: knowing what's there, where it is, whether it's sold, whether it's almost out, and what's coming tomorrow.

  • Multi-warehouse + locations

    Unlimited warehouses, with pick zones, bulk zones and pallet locations. One SKU can live in multiple places.

  • Reservations + incoming

    Free stock = gross − reserved + confirmed PO. Three balances in one view, no spreadsheet corrections.

  • Replenishment advice

    Per-SKU daily velocity and stock-out forecast. Per-supplier batched PO with lead time and MOQ baked in.

  • Expiry + batch registration

    Expiry date and batch number captured at receiving, enforced per product. Batch stock visible per location; the audit log shows which batch ended up where.

  • Cycle counts via scan

    Count a location, scan the SKU, variance straight into audit-log. No annual stocktake downtime.

  • API + webhooks

    Push stock to your shop, ERP or accounting. Real-time webhook on every mutation or a pollable REST endpoint.

Frequently asked questions

What founders and operations managers want to know up front.

How many SKUs can Tremo handle?+
No software cap: from hundreds to tens of thousands of SKUs. Free and Growth cover store volume; Core is for deep warehouse work, Enterprise for 3PLs and multi-region.
Can I import existing inventory?+
Yes, via CSV import: SKU, product name, starting stock per location. We set up the import during onboarding so the first pick can happen the same day. Variances between import and first physical count are logged so you know what you started with.
Does inventory management work offline?+
The scan-flow on phones works briefly offline (queue), but Tremo is a cloud product. For a 100% offline warehouse we recommend a local alternative — we're not built for it.
How do I connect my accounting?+
Moneybird is a direct integration. For Xero, Exact and the rest, Tremo pushes via webhooks and an open REST API you connect with a linking tool or a small script. No secret API.
Can I enforce FIFO or FEFO?+
Not yet automatically in pick order. Available today: batch number and expiry are mandatory at receiving, batch stock is visible per location and every batch movement is in the audit log.
