DealHub vs Salesforce CPQ for Engineering Fee Proposals

When a fee is quoted as a percentage of an estimated construction cost, the total professional fee needs to be split across phases, often front-loaded toward design and lighter during construction administration, and that split needs to update if the construction cost estimate itself changes during design development. DealHub's formula pricing can tie a fee to a project-cost input field and recalculate the phase breakdown when that input changes. Salesforce CPQ can do the same through formula fields, but percent-of-cost fee structures aren't a common Salesforce CPQ use case, so an admin is usually building this from scratch rather than adapting an existing template.

A structural firm might bring in a geotechnical or MEP subconsultant and mark up their fee by a standard percentage before passing it through to the client. Some clients want that markup itemized transparently; others just want a single blended professional-services number. DealHub can show subconsultant costs as their own line with a visible markup, or roll them into the total, depending on what the client relationship calls for. Salesforce CPQ handles markup pricing well through its cost-plus pricing method, which is a closer match to how engineering fee markups actually work than the percent-of-construction-cost calculation is.

Travel, printing, and other reimbursable expenses are typically billed separately from the professional fee, often at cost or cost-plus a small handling percentage, and tracked against a not-to-exceed estimate stated in the proposal. Neither DealHub nor Salesforce CPQ tracks actual expense receipts, that's a function for your accounting or expense system, but both can hold a reimbursables line with an estimated cap on the proposal itself, which is the part that actually needs to be visible to the client before work starts.

Say a structural retrofit project has an estimated construction cost of $4 million, a professional fee at 8% of that, split 30% schematic design, 30% design development, 30% construction documents, and 10% construction administration, plus a geotechnical subconsultant fee of $35,000 marked up 10%, and a reimbursables estimate capped at $6,000. Building that as one coherent proposal means combining a percent-of-cost formula, a phase-based schedule, a marked-up pass-through line, and a capped expense estimate, four different pricing mechanics in a single document. This is the scenario worth testing directly in a demo with either vendor, since a feature list won't tell you how smoothly those four pieces actually combine.

To build a proposal like this, work through the steps in order:

1. Start from the estimated construction cost and the fee percentage, then calculate the total professional fee.
2. Split that fee across schematic design, design development, construction documents and construction administration, weighting the design phases more heavily.
3. Add each subconsultant fee as its own line with the standard markup, shown or blended depending on what the client prefers.
4. Enter reimbursable expenses as a separate category with a not-to-exceed estimate stated in the proposal.
5. Update the cost estimate field whenever it changes so the remaining phase fees recalculate instead of staying frozen.

Construction cost estimates almost always move between schematic design and construction documents, usually upward as the design gets more detailed, and if the fee is genuinely tied to a percentage of that cost, the remaining phase fees should recalculate rather than stay frozen at the original estimate. Firms that quote a flat dollar fee up front and never revisit it, even when the underlying construction cost estimate moves significantly, are effectively giving away the fee increase their own contract terms would justify. DealHub's formula-linked fee can be recalculated against an updated cost estimate at each phase gate, showing the client exactly why the remaining fee moved. Salesforce CPQ can support the same recalculation, but only if the original quote was actually built on a live formula field tied to project value rather than a static number typed in once at signing.

Once a project moves into construction administration, scope frequently expands: additional site visits, RFI reviews, or change-order evaluations beyond what the original phase fee covered. That additional services work should be quoted as its own incremental line tied back to the original proposal, not folded quietly into the construction administration phase at no extra charge. A CPQ tool that makes it easy to add an additional-services line to an existing project record, rather than requiring a whole new proposal, removes the friction that usually causes firms to absorb that extra scope for free.
