--- title: "Construction Procurement Controls: Approved Materials, Suppliers & Pricing | Punch" description: "How procurement controls work in construction, with approved-materials lists, approved-supplier lists, and pre-negotiated contract pricing enforced before the PO goes out." canonical: https://buildwithpunch.com/construction-procurement-controls --- [](https://buildwithpunch.com/) [See Punch work](https://calendly.com/taylor-punch/30min?hide_event_type_details=1&hide_gdpr_banner=1) GUIDE: PROCUREMENT CONTROLS # Procurement controls that work before the order goes out Most construction companies police purchasing after the fact by reconciling invoices, chasing rogue orders, and discovering the wrong price weeks later. Procurement controls flip that: the rules are enforced at the moment of ordering, so a bad PO never reaches a supplier.

In practice, those rules live in someone’s head. The field orders what’s fastest, each PM runs purchasing their own way, and the negotiated rate sits in a contract PDF nobody opens at ordering time. The result shows up weeks later, on invoices: materials that were never approved, suppliers nobody vetted, and prices that ignore the contract. By then the material is installed and the money is spent. Reconciliation can document the drift, but it can’t undo it. The fix isn’t more policing after the fact. It’s moving the rules into the ordering workflow itself, so the check happens **before** the purchase order is sent, not after the invoice arrives. THE THREE CONTROLS ## Approved materials. Approved suppliers. Pre-negotiated pricing. Punch enforces three hard guardrails on every purchase order. They're checked when the order is created, with no workarounds or after-the-fact surprises. APPROVED MATERIALS ### Off-list orders don’t go out Define which materials can be ordered per project or company-wide. If an order contains something that isn’t on the list, Punch blocks it before it reaches the supplier. The spec stops being a suggestion. APPROVED SUPPLIERS ### Orders only go to vetted vendors Your approved-supplier list travels with every project. Punch will not send a PO to a supplier who isn’t on it. That means no unapproved substitutions or rogue vendor relationships forming in the field. CONTRACT PRICING ### Pre-negotiated rates, automatically applied Upload your negotiated price books per project and Punch applies those rates when the PO is built, so the field benefits from the contracts the office negotiated without looking anything up. Every order runs the guardrails before it goes out — the off-list item is blocked, not quietly sent. Procurement controls are configured by admins, purchasing coordinators, and other approved users. The field keeps ordering the way it always has, inside the guardrails. ## How the controls work in practice The rules are set once by the people who own purchasing policy: admins, purchasing coordinators, and other approved users. Approved-materials lists can be scoped to a single project or applied company-wide. Approved-supplier lists and pre-negotiated price books are loaded per project, typically from the contracts and quotes the office already has. From there, enforcement is automatic. When anyone creates an order [from chat, email, or the field](https://buildwithpunch.com/product/purchase-orders), Punch checks it against the project’s rules. An off-list material or an unapproved supplier stops the order before any supplier sees it. Contract pricing doesn’t need enforcement at all: the negotiated rate is simply what the PO is built with. That’s the difference between a purchasing policy and a purchasing control. A policy depends on everyone remembering it under pressure. A control works even on the busiest day of the job.
