BizBloqs × Slimstock (Slim4)

FORECASTING IS ONLY AS GOOD AS THE COUNT

Slim4 will tell you exactly what to order. It calculates that advice from your current stock position — and if that position is a guess, so is the purchase order.

BizBloqs supplies the counted position: physical, reserved, available, per location, with corrections booked as they are found.

IS THIS YOU?

Who this Slimstock (Slim4) integration is for

You bought forecasting software and your buyers still add a margin because they do not trust the stock figure.

You run Slim4 or are implementing it and stock accuracy is a known weak point.
Buyers override the advice routinely rather than occasionally.
Stock corrections are found at year-end instead of continuously.

WHAT IS SLIMSTOCK?

SLIM4 — INVENTORY OPTIMISATION AND FORECASTING

Slimstock's Slim4 forecasts demand, sets safety stock and generates replenishment advice for wholesalers, retailers and manufacturers.

Its models are strong. Their input — what you have and what is genuinely available — comes from the warehouse.

THE PURCHASE ADVICE STOPS BEING ARGUED WITH

When buyers trust the position behind the advice, they stop adding a personal safety margin on top of Slim4's safety stock.

Expected receipts, open purchase orders and returns in progress are all visible, so the advice reflects goods already on their way.

WHAT CHANGES ONCE SLIMSTOCK AND BIZBLOQS ARE CONNECTED

Stock positions, movements, receipts and corrections move between BizBloqs and Slim4 on the agreed rhythm.

Counted position per location

Slim4 receives stock per article and location as counted, not as derived from a sequence of bookings.

Physical, reserved and available split

Physical, reserved and available are reported separately, so safety stock is set against what can genuinely be sold.

Expected receipts included

Expected receipts and open purchase orders are included, which stops the advice from ordering goods that are already inbound.

Cycle-count corrections booked

Cycle counts run continuously in BizBloqs and corrections are booked immediately rather than saved up for a year-end exercise.

Receipts confirmed against PO

Goods receipts are confirmed line by line against the purchase order, so supplier reliability data is based on facts.

Advice buyers actually follow

Because the numbers hold up, buyers follow the advice instead of quietly adding their own buffer to it.

Replenishment integration

How the Slimstock (Slim4) integration works

Slim4 forecasts demand and tells you what to buy. Its advice is only as good as the stock position it is given — and in most companies that position is an ERP number that has not been counted in months. BizBloqs supplies the counted one.

Slimstock Slim4 — planning integration

Scheduled API or file exchange of stock, demand and purchase advice

BizBloqs sends the real position on the agreed rhythm: physical, reserved and available stock per location, outbound movements as demand signal, open backorders and every correction with its reason code. Slim4 returns purchase advice and confirmed purchase orders, which land in the warehouse as expected receipts — so the dock knows what is coming and when. Multi-warehouse customers get advice per location instead of one aggregated number that hides a shortage in one site behind a surplus in another.

What you need

An active Slim4 environment with your item and supplier data
Agreed exchange method (API or scheduled file) and frequency
Cycle counting running in the warehouse, so the position is trustworthy
Agreement on which system owns supplier lead times and order rules

Which messages are exchanged

This is the standard message set between BizBloqs and Slimstock (Slim4). Empty fields mean that message is not exchanged in that direction by default; optional rows depend on your modules, licence and process.

How we roll it out

1. Discovery
We walk through your current Slimstock (Slim4) setup and agree which objects are in scope and which system is leading per object.
2. Connection
The technical connection is established on a test environment first, so you can see real data moving before anything touches your live operation.
3. Mapping and testing
Fields, codes and exceptions are mapped and tested with your own orders — including the ones that normally go wrong.
4. Go live
We go live with your team on the floor, monitor the first days closely and hand over a connection your people can read themselves.

Integration FAQ

Does Slim4 replace our ERP purchasing?

No. Slim4 advises, your ERP places the order, and BizBloqs receives it against the purchase order at the dock — three roles, no overlap.

How often should stock be sent?

Daily is enough for most forecasts; faster is possible. What matters more than frequency is that the number has been counted.

What happens if the Slimstock (Slim4) connection drops?

Messages are queued and replayed. Warehouse work continues in BizBloqs during an outage; the queue drains once the connection is restored, and failed messages stay visible instead of disappearing silently.

Can we change the standard message set?

The table above is our standard integration with Slimstock (Slim4). Extra messages, different field mappings or customer-specific rules are handled through workflows in BizBloqs — we tell you upfront what is standard and what is custom work.

How long does connecting Slimstock (Slim4) take?

The connection itself is a matter of days. The realistic timeline is set by mapping and testing, and by how clean your product data and process agreements already are.

We needed a better, more transparent and practical system for our incoming and outgoing product flow. A direct overview in our stock and all our logistics movements was really a must. BizBloqs helped us from the start!

In addition to a scan procedure with EDI integration, BizBloqs has set up an entire production system for us. Production planning can provide direct instructions and as soon as they are ready, it all arrives in the OMS. This gives us a larger production capacity and a drastic reduction of the picking mistakes in dispatching.
