Ramp vs Procurify for Civil Engineering Firms Billing by Milestone

Design and structural analysis software licenses are usually the firm's largest fixed cost after payroll, priced per seat, renewed annually or multi-year, and expensive enough that adding or dropping a seat is a real budget decision, not a routine purchase. Procurify's requisition model fits this category well: a new seat request names the project or practice area driving the need, and the renewal itself becomes a scheduled, reviewed commitment rather than something that quietly auto-charges a saved card every year. Ramp can technically hold the card these renewals bill to, but without a requisition step in front of it, it's easy to keep paying for seats added for a project that wrapped up a year ago. Whichever tool you use, review software seats against active project staffing at least once a year, ideally timed to when a major project closes out, since that's naturally when staffing, and therefore seat needs, actually change.

Structural and civil engineering firms often bring in subconsultants, geotechnical, MEP, surveying, whose payment terms need to track the prime contract's own milestone or draw schedule, not a generic monthly cycle. A subconsultant paid ahead of when the firm itself gets paid on that milestone is financing the project on the firm's own balance sheet. Procurify's purchase order model fits this well: a requisition naming the specific milestone and the subconsultant's scope creates a record that ties payment timing to project progress, rather than to an arbitrary calendar date. This matters more in this industry than in most others, since receivables at engineering and construction firms run notably long: around 100.4 days on average¹, well over three months between invoicing a milestone and collecting on it.

Firms in this category typically pay their own vendors in about 36 days², a fraction of the 100.4 days it usually takes to collect. That gap is the widest of any category covered in this comparison, and it means every subconsultant or material cost paid before a milestone is invoiced is real, extended financing the firm is providing on the project's behalf. Tagging every cost to its milestone at the point of purchase, rather than reconstructing it at billing time, is the single most useful habit a firm in this industry can build regardless of which tool handles the tagging itself.

A stamped drawing carries liability the firm can't fully hand off to a subconsultant, which is a reason to review new subconsultant relationships more carefully than a typical vendor approval would require, confirming licensure and insurance before work begins, not after a project is already underway. Procurify's requisition step is a natural place to attach that confirmation, since the request already has to name who's being engaged and for what scope. A card-only approach doesn't have an obvious place to hang that check, which is one reason firms in this industry often lean toward Procurify's model even at a fairly small size.

The single most useful audit a firm in this industry can run is a project-by-project close-out review: pull every cost tagged to a project, from software time to subconsultant fees to travel, and compare it against what the project actually billed once the final milestone was invoiced and collected. This is where tagging discipline pays off, since a project with good tagging throughout takes minutes to review, while one with untagged costs scattered across card statements and email threads takes hours to reconstruct, if it can be reconstructed accurately at all. Run this review on every project above a certain size, not just the ones that felt like they ran into trouble, since the projects that quietly ran thin on margin are often the ones nobody thought to check.

A firm with a stable roster of subconsultants and predictable software needs can often run lighter on Procurify's requisition overhead and lean more on Ramp's card controls for day-to-day purchases. A firm onboarding new subconsultants project by project, with liability and licensure to confirm each time, gets more value from Procurify's documented approval chain.

Use these checks to decide how much approval structure your firm needs:

• Treat each CAD or analysis seat as a standing commitment, with a request naming the project or practice area that drives the need.
• Time subconsultant payments to the prime contract's milestone or draw schedule so the firm is not financing the project on its own balance sheet.
• Confirm subconsultant licensure and insurance at the requisition step, before work begins rather than after the project is underway.
• Compare payables timing against the long receivables cycle to see how much extended financing each project requires.
• Run a close-out review after the final milestone, comparing every tagged cost against what the project billed and collected.
