STACK Estimating Alternative for Electrical Contractors

The best STACK estimating alternative for an electrical contractor is usually a tool built around electrical assemblies and labor units rather than general multi-trade takeoff. STACK is a popular cloud takeoff and estimating platform used by general contractors and subcontractors across many trades. It's well reviewed, runs in a browser, and has a free version. Electrical contractors who look for an alternative usually want estimating that's built for electrical work, or a lower price for a small team.

Facts about STACK are from STACK's website and review sites, checked September 28, 2026. Sources are listed at the end.

STACK at a glance

What STACK does well

• Easy to learn and quick to get started, according to many reviewers.
• Cloud access from any device, which suits teams and remote estimators.
• Support is highly rated: 4.7/5 for customer service on Capterra, and a G2 support score of 9.3 against PlanSwift's 7.7.
• Beyond takeoff: field tools and integrations with Procore, Dodge, Pantera, ERP systems and an open API.

Reviewers on Capterra and G2 also like the collaboration that comes with a cloud tool, and one Capterra reviewer reports saving about 30% of the time spent on takeoff and estimating.

Why electrical contractors look for alternatives

From reviews on Capterra and G2:

• Cost for small teams. Several reviewers find the subscription expensive, particularly with AI features, and some call the plans inflexible.
• Performance on large projects. Some report slowdowns and freezes on big plan sets, and it needs a reliable internet connection.
• Measurement precision. A few Capterra reviewers mention precision complaints.
• General-purpose estimating. G2 reviewers note that estimate-level customization is limited; electrical labor units and assemblies are yours to build.

STACK vs. SparkQuote

Feature by feature

Takeoff. STACK handles quantity, labor and material takeoff from PDF and TIFF plans, with area and linear measurement and wire length calculations. Autocount "quickly counts most plan symbols" on paid plans. Floor Plan AI automates counts of doors, windows and symbols, linear walls, and gross and room areas; STACK's AI page places it in the Premium and Pro plans, with a 7-day free test. SparkQuote reads the electrical legend and counts every symbol type for review on the plan; see electrical takeoff software for the details.

Items, assemblies and labor. STACK supports custom items and assemblies, and estimates include labor, equipment, overage, profit and tax. Electrical labor units are yours to enter. SparkQuote starts with an electrical library of assemblies and labor units, with conditions by area.

Supplier pricing. We didn't find a named supplier price-service integration for electrical on STACK's pages. SparkQuote imports price lists and supplier quotes.

Proposals. Both produce proposals. STACK's include cost breakdowns; SparkQuote's pull from a library of electrical inclusions, exclusions and clarifications.

Team and integrations. STACK has multi-user permissions (edit or view-only) and integrations with Procore, Dodge, Pantera and ERP systems. SparkQuote exports to Excel.

Price. STACK's plan names differ across its own pages (the pricing page shows Takeoff & Estimate, Build & Operate and Full STACK Platform; the FAQ mentions Start, Grow and Build), so confirm which tier includes the features you need. At the published "as low as" $249 per user per month, one user is $2,988 a year and three users are $8,964.

When STACK is the better choice

• You estimate multiple trades, or you're a GC-adjacent team.
• You want field tools (reports, punch lists) on the same platform.
• You need its integrations with Procore, Dodge or your ERP.
• You want a free tier to try before you commit.

When SparkQuote is the better choice

• You're an electrical or low-voltage contractor who wants estimating built for that work.
• You want AI counting included on the entry plan, not only on higher tiers (Starter includes a set number of AI takeoffs a month; see pricing).
• You're a small team watching per-user cost.

Other alternatives to consider

• PlanSwift: multi-trade takeoff as a Windows install with published annual seat pricing. See our PlanSwift page for a PlanSwift vs. STACK summary.
• Procore Estimating (formerly Esticom): cloud estimating that hands off to Procore budgets and contracts.
• Trimble Accubid: deep electrical databases for larger commercial shops.

A fair side-by-side test

Both products can be tried without a sales call, so test them on the same job:

1. Pick a plan set you've already bid, with a takeoff you trust.
2. Run it through STACK's 7-day AI test (Autocount and export aren't in the free tier) and through the SparkQuote trial.
3. Record the time to an approved count in each, including your review.
4. Enter labor units for your ten most common items in each, and note how long it takes.
5. Build the proposal in each and ask whether you'd send it as-is.
6. Price it both ways and compare with your original bid.

Switching from STACK

1. Export your items and assemblies; paid plans support export, the free tier doesn't.
2. Use STACK for Excel if you have it: the Velixo partnership's Report Sync keeps a spreadsheet updated with your latest quantities, which makes a side-by-side check easy.
3. Import your price list and labor units into SparkQuote. We found no documented importer for other vendors' electrical databases in STACK, so plan to rebuild your most-used assemblies.
4. Re-run a recent STACK takeoff and compare counts and totals.
5. Check your renewal terms before the next billing cycle.

Questions to ask STACK's sales team

• Which plan includes Autocount and Floor Plan AI, and what does it cost per user?
• How does it perform on our largest plan sets?
• Are there electrical templates with labor units, or do we build our own?
• Can we pay monthly, and what are the cancellation terms?

Frequently asked questions

How much does STACK cost?

STACK's pricing page lists Takeoff & Estimate from $249 per user per month and the full platform from $298 per user per month (as of September 2026). A limited free version is available.

Is STACK free?

There's a free version with limits: up to two concurrent projects for seven days and ten takeoffs per project, without Autocount, cost data, API or export.

Is STACK good for electrical estimating?

It's a capable multi-trade takeoff tool with electrical templates. Contractors who want electrical-specific labor units and proposals often add their own assemblies or use an electrical-focused tool.

STACK or PlanSwift?

STACK is cloud-based with a free version; PlanSwift is a Windows desktop tool with published annual seat pricing. See our PlanSwift comparison.

Does STACK have AI takeoff?

Yes. Autocount counts plan symbols, and Floor Plan AI automates counts, linear walls and areas on higher tiers.

How do I log in to STACK?

Through STACK's own website, stackct.com; contact STACK support for account access. SparkQuote isn't connected to STACK accounts.
