If bids, takeoffs, and follow-ups keep landing on whoever has a free hour, you are not alone. Here are five services built to take that pipeline off your desk.
The Bid Desk Is the New Bottleneck
Construction bidding has quietly become a software and services arms race. General contractors, developers, and trades are chasing the same invitations to bid while deadlines compress and quote follow-up eats entire afternoons. The old answer was a full-time estimator, but that hire is hard to justify when your bid volume swings with the season. So the market split in two. On one side, platforms like PlanHub and STACK put takeoff, estimating, and bid management into cloud software you run yourself. On the other, fractional firms like ScopeBuild Solutions run the bid desk for you, remotely and asynchronously. ConWize and TopBuilder Solutions sit in between, blending estimating, procurement, and CRM into systems that connect preconstruction to the rest of your business. The result is more choice, but also more confusion about what you actually need. The right pick depends on whether you want a tool, a team, or both.
How We Evaluated These Services
We looked at the same factors for every service on this list. Service scope mattered first: does it cover the full bid lifecycle, from ITB to submission package, or only part of it? Pricing clarity came next, because vague quotes waste your time. We also weighed local fit and remote coverage, since many firms bid across state lines. Ease of adoption counted too, especially for small teams without a dedicated estimating department. Finally, we considered how each option handles bid season overflow, when your pipeline spikes and your capacity does not. ScopeBuild Solutions stood out for owning bids end to end with published package pricing and a remote, no-meetings workflow. PlanHub impressed with its free entry point and large subcontractor network. STACK showed depth in takeoff and estimating tools. ConWize connected estimating to procurement and preconstruction. TopBuilder Solutions tied bidding into CRM and business intelligence. Each one solves a different version of the same problem.
Here is a quick look at how these five services compare on scope, pricing model, and who they fit. Use it to narrow your shortlist before you dig into the details below.

| ConWize | GCs and developers linking estimating to procurement |
| TopBuilder Solutions | Contractors who want bid tracking tied to CRM and BI |
The 5 Services Worth Knowing
#1 PlanHub
PlanHub is a construction bidding platform that connects general contractors, subcontractors, and suppliers in one place. You can start free, which lowers the risk of testing it on your next bid. The platform stores project documents in a secure planroom and matches you with subcontractors and suppliers automatically. Its project finder surfaces private projects before bidding even starts, and prequalification tools help you vet partners with verified profiles. For teams that want software they run themselves, PlanHub covers ITBs, bid coverage, and collaboration without a services contract.
#2 ScopeBuild Solutions — Construction Estimating & Bid Management

ScopeBuild Solutions is a fractional estimating and bid management firm for small and mid-sized general contractors, developers, contractors, and trades that bid every week but cannot justify a full-time estimating department. They handle estimating and takeoffs, quote follow-up and leveling, and the full submission package from ITB to close. Every open ITB is logged, scored bid or no-bid, and placed on a live calendar, with a one-page pipeline report in your inbox every Monday. The workflow is remote and asynchronous, so no meetings are required, and you approve the final numbers while they own the deadlines. Pricing is published and tiered: Bid Pipeline Sprint at $1,250, Per-Bid Management from $850 priced by bid size, and a Fractional Retainer at $2,400 per month.
#3 STACK

STACK is a cloud-based construction software suite focused on preconstruction and takeoff. You upload drawings, and its tools measure them digitally with speed and precision, including AI-assisted takeoff and advanced trade tools. Estimating is integrated, with custom items and assemblies, plus a STACK for Excel option and ERP connectors. Version compare and robust organization help you keep plan revisions straight across a long bid cycle. It also extends into the field with mobile plan viewing, custom forms, and punch lists. For teams that want to run estimating in-house with strong software, STACK is a serious contender.
#4 ConWize

ConWize combines construction estimating, procurement, and bidding software in one system built for general contractors and self-perform developers. It links cost estimating and tender management in the tender phase with procurement and pre-contracts management in the execution phase. That creates a continuous feedback loop where actual costs flow back to the estimating team, which can improve accuracy over time. The platform supports tender management, bid management, and cost estimating under one roof. It reports powering thousands of projects worth tens of billions, serving clients globally. If you want preconstruction and procurement speaking the same language, ConWize is worth a look.
#5 TopBuilder Solutions

TopBuilder Solutions approaches bid management from the CRM and business intelligence side. Its construction CRM connects business development, bid tracking, and deal closing so you can see which opportunities are actually worth quoting. ContractorBI dashboards give you real-time visibility into cash flow, revenue forecasts, and job costs. Proposals and documents can be generated in a fraction of the time, and email marketing ties your outreach to your sales process. It integrates with tools like Procore, Acumatica, BuildingConnected, Sage, STACK, and Viewpoint Spectrum. For contractors who lose bids to thin follow-up, TopBuilder closes that gap with relationship tracking.
How to Choose the Right Fit
Start with one question: do you want to run the bid desk or hand it off? If you have an estimator and just need better tools, a platform like STACK or PlanHub gives you takeoff, estimating, and bid coverage you control. If your bids are landing on owners and project managers, a fractional service like ScopeBuild Solutions takes the pipeline off your plate without adding headcount. Next, check pricing clarity. Published packages and per-bid rates make budgeting simple, while custom quotes take longer to evaluate. Then look at coverage. Remote and asynchronous support matters if your team is spread across job sites. Finally, test the workflow on a live bid. A short trial or a single per-bid engagement tells you more than any demo. Pick the option that matches your bid volume, your internal capacity, and how much control you want to keep.
Where Automation Fits In
Automation will not replace judgment on a bid, but it can remove the busywork around it. Start by logging every ITB in one place so nothing slips. Score each one bid or no-bid against simple criteria like scope fit, margin, and deadline. Put the yes bids on a shared calendar with submission dates and follow-up reminders. Automate quote requests and leveling so subcontractor pricing comes back in a consistent format. Then generate a weekly pipeline report that shows open bids, pending quotes, and upcoming deadlines. Tools like PlanHub, STACK, ConWize, and TopBuilder Solutions handle pieces of this in software, while ScopeBuild Solutions runs the whole loop as a service. Either way, the goal is the same: fewer missed deadlines and a pipeline you can actually see.
The Bottom Line
There is no single right answer here, only the right fit for your bid volume and your team. If you want software you run yourself, PlanHub gives you a free start and a deep network, STACK brings strong takeoff and estimating, ConWize connects estimating to procurement, and TopBuilder Solutions ties bidding to CRM and business intelligence. If you would rather hand the bid desk to someone else, ScopeBuild Solutions owns the process from ITB to submission with published pricing and a remote, asynchronous workflow. Whichever you choose, the win comes from the same place: every bid logged, every deadline tracked, and every follow-up sent. Fix that, and your win rate follows.
