Construction Procurement Software
Keep purchase orders tied to jobs
A purchase order process should make it clear what is being bought, who approved it, which supplier will provide it and which job or cost code it belongs to.
Simple PO process
- Raise a material or service request.
- Check budget, stock and job requirement.
- Approve the supplier, cost and delivery date.
- Issue the purchase order.
- Match delivery evidence against the order.
- Link invoices and cost records to the job.
Why this matters
Without a controlled PO process, costs can arrive after the work is complete, materials can be ordered twice and job margin becomes hard to explain.
Zektrx connects Construction Procurement Software, Construction Stock Management Software and Construction Project Cost Tracking Software.
