8. التعليمات

س1: How do you ensure your network of quarry sites in Lagos actually offers the best price?
We conduct blind RFQs against your exact specifications across our network without disclosing the end buyer initially. This ensures quoted prices are competitive market rates before any negotiation.

Q2: What happens if there is a delivery dispute or substandard material?
As your contracted agent, we assume responsibility for resolution with the supplier on your behalf. This includes coordinating replacements or financial remedies per our agreement terms.

س3: Are your services suitable for a small project requiring only a few truckloads?
For very small volumes (<100 طن), our service model may not be costeffective unless it is part of a larger ongoing relationship.

س 4: How do you handle logistics coordination with my own preferred transporter fleet?
We can operate flexibly—either managing endtoend logistics using our vetted partners or simply providing sourced materials at the quarry gate for pickup by your fleet.

س5:What documentation do you provide?
Standard documentation includes weighbridge tickets/quarry receipts; commercial invoices; transport waybills; plus optional Mill Test Certificates/Lab Reports where applicable.

س6:What is your typical response time once we provide our requirements?
Binding quotations from compliant suppliers are typically presented within two business days.

س7:What are the payment terms when using an agent?
Terms vary but commonly involve direct payment from you to the verified supplier upon proofofdelivery; our service fee is then invoiced separately per our agreement
