Supply chain software for importers, distributors and factories

Purchase orders, supplier lead times, landed cost and stock on one ledger for Cambodian importers and distributors. We map the buy side to the books: PO to goods receipt to landed cost to the VAT line, in KHR and USD at the NBC daily rate. ERP owns the ledger end to end; this is the buy side that feeds it.

What does supply chain software actually do for a Cambodian importer?

It records the buy side: what you ordered, what arrived, what it cost once duty and freight landed, and what that leaves on the books. The point is not the purchase order. The point is that the cost you sell at is the cost you actually paid, without anyone retyping it into a second system.

For an importer in Phnom Penh that usually means four things happening in one place: a supplier record with real lead times, a purchase order you can match against what turned up, a landed cost that includes duty and freight rather than the invoice line alone, and a stock valuation the monthly return can be built from.

Where does stock actually change hands?

At goods receipt, once. Everything before that is a promise: a quotation, a confirmed order, a container on the water. Treating any of it as stock is how a business ends up selling what it does not have. The receipt is the row your accounts read, and it is the only row that moves the valuation.

How do you calculate landed cost on an import?

Take the supplier invoice, add freight, add insurance, add duty, add any clearance charge, then spread the total across the units received. What you get is the cost that should sit on the stock line and flow into COGS when you sell. Converted at the NBC daily rate on the invoice date, not a period average.

• PO raised against a supplier record that carries a real lead time
• Supplier confirmation, which is when the lead-time clock starts
• Shipment, with freight and insurance accruing against the same PO
• Duty and VAT on import, recorded against the shipment rather than the month
• Goods receipt — custody changes, and stock moves for the first time
• Landed-cost allocation across the units actually received
• Stock valuation, then COGS when the unit sells
• The VAT line on the monthly return, traceable back to the PO

When do I reorder?

On a rule you set: a reorder point per item, a minimum and maximum level, and an alert when stock crosses it. That is what we ship today, and for most Cambodian distributors it is the whole job. A reorder rule reads what already happened. A forecast predicts what has not. We ship the first today; the second is in design.

The distinction matters more than it sounds. A rule you can read and argue with is auditable: someone chose 40 units, and you can ask them why. A model that has never seen your sales history is not a better version of that rule, it is a guess wearing a lab coat. We would rather build the ledger that produces the history first.

Odoo Purchase, SAP Business One, Acumatica, or the spreadsheet you have now

The spreadsheet is not the enemy. It is honest about being a spreadsheet, and for a business under a few hundred SKUs it is often enough. What it cannot do is carry landed cost into a stock valuation your accountant will sign. That is the line worth watching, and it is usually crossed before anyone notices.

We are vendor-independent and take no referral fees, so the answer here is genuinely open. Odoo Purchase is where most single-entity Cambodian SMBs should start. SAP Business One earns its cost when a parent company already runs SAP. Acumatica competes on licensing model rather than features. Where none of them fit the flow, we build it.
