The Best Software Stack for Subcontractors (2026)

Subcontractors buy software under a constraint general contractors do not have: some of your stack is chosen by your customers.

A GC picks Procore and you are in Procore, as a guest, with a login you did not want and a workflow you did not design. Another GC uses Autodesk Build. A third sends pay applications through Textura. None of it integrates with your accounting system, and all of it is mandatory if you want the work.

So a sub's stack is really two stacks: the tools you chose to run your business, and the tools your customers require you to appear in. Most guides to subcontractor software ignore the second entirely, which is how you end up with a recommendation list that assumes you get to make all the decisions.

This guide goes layer by layer, is honest about which layers you actually control, and names the specific integration gap where the money leaks.

Two disclosures. We build CostCrunch, which audits material invoices, so weigh the last section accordingly. On pricing: where a vendor publishes, prices are below and were current at our last check; where they don't, this guide says so. That is not a formality here — one of the largest vendors in this space stopped publishing tiers entirely in 2026, and third-party figures for another actively contradict each other.

Layer 1: estimating and takeoff — the layer you fully control

This is where a sub's margin is decided, and the only layer where nobody else has a vote.

It is also the most trade-specific layer in the whole stack, which is why it gets covered in the trade guides rather than here: commercial electrical runs Accubid, ConEst IntelliBid, or McCormick against a TRA-SER or NetPricer price file; commercial plumbing and mechanical runs FastEST, Trimble Estimation, QuoteSoft, or WenPipe against Harrison and PHCC labor units; steel framing runs Strucsoft or Vertex BD and prices off a weekly index.

The cross-trade options are STACK for cloud takeoff, which publishes per-seat annual pricing that varies by seat count, Togal.AI for AI takeoff at published per-user monthly rates, and Bluebeam or PlanSwift as the general-purpose measuring tools most estimators already have.

The thing worth knowing across all of them: trade-specific estimating with a maintained price file and labor units beats general-purpose takeoff for a specialty contractor, and the price file is the part people underbudget. Generic takeoff gives you accurate quantities and no opinion about what they cost.

Layer 2: project management — the layer you don't control

Here is the uncomfortable part. You will be in whatever your GCs use.

Procore dominates, and it is worth understanding how it is priced because it explains why your GC behaves the way they do. Procore publishes no dollar figures. Its pricing page states the model verbatim: an upfront annual fee by product, based on Annual Construction Volume — the aggregate dollar value of construction work across your projects — with unlimited users, unlimited data storage, and 24/7 support included at no extra cost.

That model has two consequences for you. First, adding your people costs your GC nothing, which is why you get invited freely. Second, Procore's own filings show 114% net revenue retention, meaning existing customers paid about 14% more year over year — so your GC's costs rise as their volume rises, and renewal pressure is real.

Practitioner criticism of Procore is consistent and worth knowing even as a guest: pricing scales with construction volume and catches teams off guard at renewal, implementation runs months rather than days, and the interface is internally inconsistent — as one review puts it, every Procore tool is different, some auto-save while others require manual saving, and dropdown lists are inconsistent. Firms under roughly $10M to $20M generally find it too heavy to justify buying for themselves.

Autodesk Construction Cloud is the main alternative you will be invited into. We are not publishing a price for it: third-party figures range from a low per-user monthly rate to figures an order of magnitude higher, they contradict each other directly, and some aggregators conflate ACC with Autodesk Forma, a different product. Get a quote.

Fieldwire (Hilti) is the one tool in this layer a sub commonly buys for itself. It publishes pricing, including a free tier, with paid per-user monthly tiers. It handles plans, tasks, and punch in the field without a platform commitment, and it is the sensible answer when you want your own field coordination rather than living in a customer's system.

A note on stale recommendations. If a 2026 guide recommends CoConstruct, stop reading it. Buildertrend acquired CoConstruct in January 2021 and retired it as a standalone product by 2022, migrating customers over. It is now a brand, not a product you can buy. Relatedly, Buildertrend removed its published pricing tiers in 2026 — the Essential, Advanced, and Complete plans are gone, replaced by a custom-quote workflow keyed to 11 annual construction volume brackets. Any figure you find for those tiers is now historical.

Layer 3: accounting and ERP — the decision that constrains everything

This is the layer you control that most determines what else you can buy, because integration availability is a function of your accounting system.

The clearest guidance available maps to revenue bands:

That last row is described in construction accounting circles as the dominant architectural pattern in commercial construction. Sage 300 CRE is variously positioned as suiting $10M to $500M or as really being for $50M-plus firms with multi-entity structures and dedicated IT — which tells you the honest answer depends more on your complexity than your revenue.

QuickBooks Online publishes pricing, and it increased on August 1, 2026: Simple Start $38, Essentials $85, Plus $140, Advanced $340 per month. It is genuinely sufficient below about $5M without prevailing-wage work, and it lacks committed costs, percentage-of-completion, cost-to-complete, AIA progress billing, and certified payroll — the things a commercial sub is measured and paid on.

Sage 100 Contractor, Foundation, Sage 300 CRE, Sage Intacct Construction, Viewpoint Vista, Spectrum, and CMiC are the construction-native options. None publish pricing. Implementation for this tier is commonly quoted in the $10,000 to $50,000 range for setup, migration, and training, and that is a third-party range rather than a vendor figure — get yours in writing.

The integration gap, which is the real finding in this layer

The recurring theme in construction accounting commentary is not that either system is bad. It is the seam between them:

The gap between those two systems is where margin gets lost, with sync delays, missing historical data, hard-coded cost code rules, and workarounds for WIP reporting adding overhead that grows with every new project.

Procore's QuickBooks and Sage integrations have documented limitations, and the practical symptom is the one most finance people in construction will recognize immediately: the finance team is still keying job costs into a separate ledger at the end of the month.

If that describes you, the fix is usually not a new ERP. It is closing the specific seam — which sync fails, which fields do not map, and which report gets rebuilt by hand — before spending six figures on a migration that may reproduce it.

Layer 4: getting paid — the layer subs care about most and guides cover least

Unique to subcontracting, and frequently the largest working-capital lever available.

Siteline is built specifically for trade contractor billing: pay applications, lien waivers, and compliance, with integrations into the Textura and GCPay portals your GCs use. Pricing not published.

GCPay (an Autodesk company) and Oracle Textura are the GC-side platforms you submit into. You generally do not choose these; you comply with them. Neither publishes pricing.

Why this layer matters more than its coverage suggests. A sub's pay application is a document with retainage, stored materials, schedule-of-values line items, and lien waiver requirements attached, submitted into whichever portal each GC mandates, on each GC's calendar. Getting it wrong delays payment by a full billing cycle. There is no equivalent problem on the GC side, which is part of why the software market underserves it.

Layer 5: procurement and material buying

Relevant to self-performing subs with real material spend, which is most of them.

Kojo (strongest in MEP, published trade list of concrete, drywall, electrical, flooring, mechanical, and roofing), Field Materials (deepest ERP integrations, AP-first), SubBase (explicitly targets commercial specialty trades and self-performing GCs above roughly $10M, best where field adoption is the risk), Trimble Materials (the former StructShare, best if you run Viewpoint or Sage 300), DigiBuild and Raiven (sourcing-speed and network-pricing plays respectively). None publish pricing. Full detail in our procurement roundup.

The caution that applies to this entire layer: a procurement platform is a system of record, and its value is proportional to how completely your crews use it. Roughly speaking, technology rollouts stall on employee resistance more than on capability, and field-facing tools carry the most of that risk. If foremen keep calling the supply house directly, the data is partial and most of the projected savings never appear. Weigh field adoption as heavily as the feature list, and ask any reference customer what percentage of their material requests actually originate in the platform six months after go-live.

Layer 6: accounts payable

The requirement for a sub is line-item sync with job, cost code, and phase — not bill-level posting. Generic AP tools give you faster approvals and job costing that stays approximate.

Covered in full in our AP automation guide; the analysis is trade-independent. The short version: Ramp and BILL publish pricing and are not job-cost aware; Stampli, AvidXchange, Field Materials, and MakersHub handle construction coding and are quote-only. The volume threshold where automation pays for itself sits around 200 vendor invoices a month.

Layer 7: workforce and time

Arcoro publishes ExakTime pricing from $9 per employee per month for Time Essential, $11 for Professional, and $19 for Time plus Payroll, billed annually with volume pricing above 200 employees. busybusy runs from a free tier up to a low per-user rate with Gusto-powered payroll. Miter is construction-native workforce and payroll; pricing not published.

Certified payroll is the decider. If you do prevailing-wage public work, this stops being a convenience feature, and it is the main reason Foundation gets bought at the accounting layer.

Layer 8: the layer most subs don't have — price control

Every layer above either produces a number, moves a number, or records a number. None of them ask whether the number was right.

Estimating maintains what material should cost. Procurement records what you ordered. AP confirms the invoice agrees with the order. Accounting posts it. At no point does anything compare a unit price against what that item costs elsewhere in your market this month.

This is not an oversight in any individual product — it is a data problem none of them are positioned to solve, because they all work from your own documents. And it is the layer where the 4-8% sits.

Stacks that actually exist

Small specialty sub, under $5M: Trade estimating tool → QuickBooks Online → Fieldwire → guest logins in customers' Procore → Ramp for AP → Arcoro or busybusy for time

Mid-size commercial sub, $10M-$50M: Trade estimating with a maintained price file → Sage 100 Contractor or Foundation → guest in Procore and ACC → Siteline for pay apps into Textura and GCPay → Kojo or Field Materials for procurement → Stampli or AvidXchange for AP → Arcoro → invoice auditing on material

Large self-performing sub, $50M+: Enterprise trade estimating → Sage 300 CRE, Viewpoint Vista, or Sage Intacct → own Procore instance → Siteline → Kojo plus warehouse and tool tracking → AvidXchange → Miter or Arcoro → invoice auditing on material

How to choose

1. Start at accounting, not at project management. Your accounting system determines what integrates. Choosing a procurement or AP tool before you know whether you are staying on QuickBooks is how firms end up with double entry.

2. Do not buy what your customers will give you. You will get Procore and ACC access as a guest. Buy Fieldwire if you want your own field tool; do not buy a platform to mirror your customers'.

3. Fix the seam before you migrate. If month-end involves rekeying job costs, diagnose which sync fails and which report is rebuilt by hand. That is often a configuration problem masquerading as an ERP problem, and ERP migrations reproduce seams they do not fix.

4. Weight getting paid properly. Pay-app and lien-waiver discipline moves cash faster than most efficiency gains elsewhere in the stack.

5. Separate ordering problems from pricing problems. The single most common expensive mistake: buying a procurement platform because material costs feel high. Platforms impose control on how material is ordered. Whether the price was good is a different question they cannot answer from your own paperwork.

Questions to ask on every demo

• Does this post line-item detail with job, cost code, and phase, or one bill-level entry?
• Which of my GCs' systems does it read from or write to?
• Is pricing published? If not, what is the all-in first-year cost including implementation, in writing?
• What breaks at month-end today, and does this actually close that specific gap?
• What does your price analysis compare against — my own history, or external market data?

Where CostCrunch fits — and where it doesn't

We build CostCrunch, so treat this accordingly.

It is layer 8 and nothing else. Not estimating, not project management, not accounting, not pay applications, not procurement — no requisitions, no purchase orders, no receiving, no inventory. Every other layer above needs a product from that layer's list.

What it does: you forward material and supply invoices to an email address, every line item is extracted at 99% accuracy and checked against your own purchase history and local market rates, and overcharges, duplicate charges, quantity errors, and price creep are flagged before you approve. Verified line-item data syncs to QuickBooks, Sage, or FreshBooks.

The reason it is a separate layer rather than a feature of one above: three-way matching confirms the invoice agrees with the PO and the delivery. That is valuable and it structurally cannot tell you the price on the PO was 11% over market when you agreed to it. Every document matches. You still overpaid. Across $125M+ in audited invoices from 500+ companies, contractors overpay an average of 4-8% on materials — $20,000 to $40,000 a year on $500K of material spend.

It is trade-agnostic on purpose: it reads whatever is on your invoices, so it works the same for a concrete sub and an electrical sub, and it audits the counter pickups and emergency runs that never touched a PO. Setup is about five minutes with no field workflow change, and there is a free tier.

Frequently asked questions

What software does a subcontractor actually need?

Eight layers, though not all at once: trade-specific estimating and takeoff, project management (usually access to whatever your general contractors use rather than something you buy), construction accounting appropriate to your revenue and complexity, pay application and lien waiver management, material procurement if you self-perform, accounts payable with line-item job costing, time tracking and payroll with certified payroll if you do public work, and price verification on material spend. Start with accounting, because it determines what integrates with everything else.

How much does a subcontractor software stack cost?

It depends heavily on size, and much of the category does not publish pricing. Published figures at our last check: QuickBooks Online $38 to $340 per month, Arcoro time tracking from $9 per employee monthly, and Fieldwire from a free tier through paid per-user tiers. Procore publishes an annual-construction-volume formula with no dollar figures. Buildertrend stopped publishing tiers in 2026. Sage, Foundation, Viewpoint, CMiC, Siteline, GCPay, Kojo, Field Materials, and SubBase all quote after a demo, and construction ERP implementation is commonly cited at $10,000 to $50,000 as a third-party range.

Do subcontractors have to pay for Procore?

Usually not as a guest. Procore charges an annual fee by product based on the general contractor's Annual Construction Volume, with unlimited users included, so adding your team to a GC's project costs the GC nothing extra and you are typically invited at no cost to you. Subcontractors who buy their own Procore instance are generally larger self-performing firms managing their own projects. Below roughly $10M to $20M in revenue, most subs find buying Procore themselves hard to justify.

Is Buildertrend or CoConstruct better for subcontractors?

That comparison is out of date: CoConstruct no longer exists as a product. Buildertrend acquired it in January 2021 and retired it as a standalone by 2022, migrating customers to Buildertrend. Any 2026 guide still recommending CoConstruct has not been updated. Buildertrend itself also removed its published pricing tiers in 2026, replacing Essential, Advanced, and Complete with a custom-quote process keyed to 11 annual construction volume brackets — so published figures for those tiers are now historical. Both are also more oriented toward residential builders than commercial specialty trades.

Where do subcontractors lose money in their software stack?

Most commonly at the seam between project management and accounting. Construction accounting commentary consistently identifies sync delays, missing historical data, hard-coded cost code rules, and manual workarounds for WIP reporting as the place margin disappears, and the recognizable symptom is a finance team rekeying job costs into a separate ledger at month-end. The second common leak is material pricing: every layer of the stack works from your own documents, so nothing verifies that a unit price was competitive in your market.

What is the best accounting software for a subcontractor?

By revenue and complexity rather than by preference. Under about $5M without prevailing-wage work, QuickBooks Online is generally sufficient. From roughly $5M to $25M, Sage 100 Contractor or Foundation become appropriate once you need AIA progress billing, retainage, and certified payroll. Above about $20M in commercial work, Procore paired with Sage 300 CRE or Sage Intacct is the common pattern. Foundation is specifically strong on certified payroll, which is often the deciding requirement for public work.

Do subcontractors need procurement software?

Only if material ordering is genuinely disorganized — no purchase orders, no records, no visibility between order and delivery. Procurement platforms are systems of record whose value depends on consistent use, and field-facing rollouts fail on adoption more than on capability. If ordering already works and the real question is whether prices are competitive, a procurement rollout is a slow and expensive way to answer it. Ask any reference customer what share of their material requests originate in the platform six months after go-live.

What software helps subcontractors get paid faster?

Pay application and lien waiver tooling, which is the most underrated layer in a sub's stack. Siteline is purpose-built for trade contractor billing and integrates with the Textura and GCPay portals general contractors use for submission. Because pay applications carry retainage, stored materials, schedule-of-values detail, and waiver requirements, and because each GC mandates its own portal and calendar, an error typically costs a full billing cycle. Pricing is not published for Siteline, GCPay, or Textura.

---

The two structural facts about buying software as a subcontractor are that you do not control your whole stack, and that the layers you do control are joined by seams nobody sells a product for. Most of the wasted spend in this category comes from buying a new system to fix a seam.

Start at accounting, close the month-end gap before migrating anything, get the pay applications right, and treat material pricing as its own question rather than a byproduct of ordering.
