Built for direct materials, not indirect spend

Fast approvals isn't a
supply chain strategy.

Modern spend platforms are great at controlling who can buy what. They weren't built to run complex supply chains.

Trusted by advanced manufacturers building hard things

Six reasons direct procurement teams choose Silkline over spend-control tools

Everything you need to source, buy, and track direct materials. Not a repurposed approvals workflow.

Built for direct materials, not indirect spend

Spend-control platforms were built to manage software subscriptions and service purchases. Silkline runs sourcing, RFQs, and POs for the physical parts and materials that go into what you build.

Engineering data connected to sourcing

Silkline carries multi-level BOMs, part revisions, drawings, and quality requirements directly into sourcing and purchasing, keeping procurement aligned with the latest engineering definition.

Suppliers reply from their inbox

No portal logins, no supplier onboarding. Your manufacturing suppliers work the way they already do. They reply to RFQs and POs by email.

Quality and compliance built in

Approval workflows end at the PO. Silkline carries the part through receipt, inspection, and audit-ready quality documentation.

One system, not another tool next to your ERP

Spend tools add another interface on top of your existing stack. Silkline connects engineering, procurement, quality, and finance around the same live data.

Secure by design, ITAR compliant

Built to the security and export-control standards regulated manufacturers already have to meet. It's not a generic spend tool retrofitted for compliance.

Spend control and supply chain control aren't the same job.

See the difference between a tool that approves purchases and a system that runs your direct materials supply chain.

Questions teams ask before they break free

We already use a spend-management tool for approvals. Do we need Silkline too?

Most teams do. Spend-management tools are built to control indirect purchases like software and services. Silkline runs the sourcing, supplier collaboration, and quality workflows for direct materials: the parts and assemblies that go into what you build. Many of our customers run both, for different parts of the business.

Do you charge per seat?

Never! We believe procurement is a team sport. Add all of your users without thinking twice.

How long does it take to get live?

Most teams are running their first RFQ or PO within days, not months.

How does Silkline use AI?

Silkline embeds AI throughout hundreds of workflows, but we don’t make it the headline. We think AI is most powerful in a supporting role: removing friction, cleaning and organizing data, automating repetitive work, and making complex processes feel simple.

Does Silkline replace our ERP, MES, or PLM?

No. Silkline connects to your existing ERP, MES, and PLM and becomes the system of action for procurement workflows.

Is Silkline secure and ITAR compliant?

Yes. Silkline is built to meet the security and access-control requirements regulated manufacturers and their supply chains require, including ITAR.

Can Silkline handle our compliance and quality documentation?

Yes. Quality traceability for ISO 9001, AS9100, and NQA-1, plus FAR/DFARS documentation, is built into the platform, not a separate module.
