Ramp vs Procurify for a DCAA-Compliant Contractor's Purchasing

Federal Acquisition Regulation cost principles distinguish allowable costs, ones the government will reimburse, from unallowable costs, like certain entertainment or lobbying expenses, and a contractor's accounting system needs to make that distinction cleanly, not reconstruct it after the fact. A purchase order system with cost category coding built into the requisition itself makes that separation a normal part of purchasing; a card charge with no coding structure leaves it to a bookkeeper guessing at categorization weeks later, which is exactly the kind of gap a DCAA audit is built to find.

Getting this wrong isn't just a documentation inconvenience, it can affect what the contractor can actually bill the government for on a cost-reimbursable contract.

Beyond allowable versus unallowable, DCAA-compliant accounting requires costs to be allocated to the correct direct contract or indirect cost pool, general and administrative, overhead, fringe, consistently and defensibly. A requisition tied to a specific contract number or cost pool at the point of purchase produces that allocation as a byproduct of normal purchasing; retroactively allocating a stack of undifferentiated card charges to the right pools is exactly the kind of manual reconstruction that both wastes staff time and introduces allocation errors an auditor will flag.

This is arguably the single strongest argument for a requisition-based system over a card-first approach in this specific industry, more than any other factor in the comparison.

A DCAA accounting system review specifically checks for evidence of internal controls: documented approval before spend, segregation of duties, and consistent application of the contractor's own written purchasing policy. A requisition workflow with approval steps built in generates that evidence automatically; a card program can be configured to require similar documentation, but it takes deliberate setup to make a card-first system produce the same audit trail a requisition system provides by default.

Contractors that treat this as a paperwork exercise rather than a real control tend to discover the gap during their first system review, which is a far more expensive time to discover it than during initial setup, since a failed review can delay the contractor's ability to bill on cost-reimbursable work altogether.

Depending on the contract, vendors and subcontractors may need to be vetted for security clearance requirements, ITAR compliance, or other federal contracting requirements beyond ordinary business due diligence, and a structured vendor onboarding process that captures this vetting once, before a vendor is used, is more defensible than assuming it happened informally. This isn't unique to procurement tool choice, but it reinforces the same conclusion: a structured, documented process beats an informal one in this industry more than in most others, given what's actually being checked during a review.

That vetting step is a one-time cost per vendor, not an ongoing burden, so it shouldn't meaningfully slow down purchasing once a vendor relationship is established and cleared, which makes it a reasonable upfront investment rather than a recurring drag on the procurement process.

Say a contractor wins its first cost-reimbursable contract and needs a DCAA-compliant accounting system in place before billing can begin. If every purchase from day one is routed through a requisition tied to the contract number, with cost category and allowability determined at the point of request, the accounting system review finds a clean, consistent trail matching the contractor's own written policy. If purchasing ran informally on cards for months before anyone thought about DCAA requirements, the same review instead finds undifferentiated charges that have to be reconstructed and re-categorized retroactively, a process that's both expensive in staff time and much more likely to surface findings that delay approval to bill.

Preparing for a first accounting system review comes down to these steps:

1. Route every purchase from day one through a requisition tied to the contract number, before billing on a cost-reimbursable contract begins.
2. Determine cost category and allowability at the point of request, instead of guessing at categorization weeks later.
3. Allocate each cost to the correct direct contract or indirect cost pool, such as general and administrative, overhead or fringe.
4. Build approval steps and segregation of duties into the workflow, so the trail matches the contractor's written purchasing policy.
5. Vet vendors for clearance, ITAR or other federal requirements once at onboarding, before any vendor is used.
