Cold-chain monitoring for pharma and food distribution
ColdLatch watches every cold room and every truck. When product is at risk it tells QA, and turns their signed decision into a stock block in SAP, minutes after the temperature moved.
Or look around a live demo company, no sign-up.
The same warm Monday morning, twice. What changes is who finds out, and when.
3 days until anyone acts
By then the product is already with customers.
22 minutes until the batch is blocked
Nobody can pick it, and the record shows why.
Both bars are drawn to the same scale.
These are real screens, not mock-ups.
Monitor
One tile per storage unit and per truck on the road, each with its current temperature and its last 24 hours. Out-of-range units and alerts waiting for a decision are sorted to the top.
Decide
The alert shows the excursion on a chart you can read value by value, and says in plain words what approving would block in SAP. Approve or reject with your password and a reason.
Prove
Every reading, decision and SAP posting lands in an audit log with who, when, and what changed. Entries are chained together cryptographically, and one button verifies the whole chain.
Open a demo company with simulated cold rooms, shipments and alerts. Read-only, no sign-up.
Five steps, the same every time, each one recorded.
A logger in a cold room, a freezer or a truck reports a temperature outside the product's profile, for example 2 to 8 °C for vaccines.
A door opened for a minute is not an incident. Once readings stay out for the profile's grace period, ColdLatch alerts QA by email, Slack or your own system.
For a storage unit, ColdLatch looks up the unrestricted stock at that SAP plant and storage location. For a shipment, the batches on board. Each gets a proposed block.
The decision screen says exactly what would be blocked. Approving or rejecting takes the user's password and a reason, every time.
Approved blocks are posted to S/4HANA and the document number comes back. Goods on the road are blocked on receipt. Everything lands in an audit log that cannot be edited.
ColdLatch is designed around what Good Distribution Practice and electronic-records rules ask of a system. It supports your compliance; your validation and your procedures remain yours.
Bring your own loggers and keep your ERP. ColdLatch sits between them.
None of this exists yet. Tell us which one you need and we will write to you when it ships. What gets asked for most gets built first.
Block affected lots by moving them to a quarantine location, for companies that run Odoo instead of SAP.
The same excursion-to-block flow for Business Central inventory.
For smaller SAP shops that are not on S/4HANA.
Reach the on-call person when an excursion is confirmed out of hours.
Alerts in the channel your QA team already uses.
Start and receive shipments from the cab, approve from your phone.
Humidity limits and door-open events alongside temperature.
A signed report per excursion, ready for the batch record.

You pay for what you monitor, never for how many people log in. A monitored point is one storage unit or one truck logger.
Founding price for our first ten customers. Sign as one of them and pay €149 or €449 a month instead of the list price, held for 24 months.
That is the Starter plan with 8 extra points: €245 per month for your whole company at the founding price (list €445), about €14 per monitored point.

Pay only for what costs extra to run or what only some companies need. Everything else goes into the plans.
"Planned" items are on the roadmap and cannot be bought yet; the price is published so you can budget. Microsoft Teams alerts, humidity and door sensors and the mobile app will be part of every plan when they ship.
You bring the loggers. ColdLatch is software: it works with any logger that publishes over MQTT, and your SAP licence stays yours. Neither is part of the price.
Prices are per company and exclude VAT. Pay monthly and cancel any month, or pay yearly and get two months free and no setup fee. List prices are €349 (Starter) and €649 (Growth) a month; the founding price applies to the first ten customers for their first 24 months.

ColdLatch is priced per company, per month, by the number of monitored points. A monitored point is one storage unit or one truck logger. Every plan includes unlimited users, unlimited alerts and unlimited SAP postings, so adding colleagues never changes the price. The first ten customers pay a founding price of €149 (Starter) or €449 (Growth) a month for 24 months; the list prices are €349 and €649. A one-time setup fee of €500 or €1,000 covers connecting SAP and is waived when you pay yearly.
Once a reading has been outside the product's temperature profile for longer than the profile's grace period, ColdLatch confirms an excursion and raises an alert. It looks up the affected stock in SAP, proposes a block for each batch, and notifies QA. A QA user approves or rejects each block with their password and a reason, and approved blocks are posted to SAP S/4HANA.
ColdLatch integrates with SAP S/4HANA through its standard OData APIs for material stock and material documents. It can also send alert notifications by email, to Slack, and to any system that accepts a signed webhook.
Yes, if you choose to. Each organisation picks one of three modes: notify only, suggest blocks for QA to decide (the default), or approve blocks automatically with a system signature. Changing the mode itself requires a signed decision by an administrator.
QA can decide while the shipment is on the road. The approved block is held and posted to SAP as soon as the shipment is marked as received, when the stock exists at the destination storage location.
Every change is written to an append-only log that the database itself prevents from being edited or deleted. Each entry stores a cryptographic hash of its contents and of the previous entry, so altering or removing any entry breaks the chain. An administrator can verify the whole chain with one button.
Any logger that can publish readings over MQTT, directly or through a gateway. In production the broker is AWS IoT Core, where each device has its own certificate and may publish only to its own topic.
In the European Union. Each customer's data is separated by tenant, credentials for connected systems are encrypted at rest, and the database is backed up off-site every night.
