Construction accounting software for job costing and progress billing has no universal winner. QuickBooks Online Plus is the practical starting point for many small US contractors; Foundation or Sage 100 Contractor fit firms that need construction payroll, certified payroll, retainage and a contractor-specific ledger; and Sage Intacct Construction is aimed at multi-entity businesses that need cloud consolidation and WIP reporting. Knowify or Planyard can add pay applications, commitments and field cost control while the accounting ledger remains elsewhere.
The deciding factors are contract type, payroll complexity, retainage, committed costs, WIP and the number of legal entities—not revenue alone. The comparisons and prices below reflect US sources checked in October and November 2026; quote-only products should be priced against the same implementation scope.

What should construction accounting software do?
Construction accounting software must connect the job, cost code, cost type, contract, commitment, payroll entry, bill and general ledger. A general ledger can tell an owner how much the company spent; a construction system must also show whether the Elm Street remodel is profitable before month-end close, which subcontract commitments are still coming, how much retainage is owed in each direction and whether the WIP schedule agrees with the books.
- Job costing: labor, material, equipment, subcontract and other costs posted to a job and phase or cost code, with budget, actual, committed and forecast values.
- Committed costs: approved purchase orders and subcontracts reduce the remaining forecast before an invoice arrives.
- Progress billing: a schedule of values carries work completed and stored, prior billings, change orders, retainage and the amount due this period.
- Retainage: owner-held retainage receivable and subcontractor retainage payable remain separate, age correctly and can be released through a controlled step.
- WIP: the system calculates earned revenue, overbilling liabilities and underbilling assets consistently and posts a journal entry that ties to the ledger.
- Payroll: certified payroll, union locals and fringes, multi-state withholding and burdened labor must flow to the correct job.
- Controls: lien-waiver status, change-order approvals, audit trails and role-based permissions prevent a pay app or payment from bypassing the job record.
How are job costing, progress billing and WIP different?

| Capability | Question it answers | What to verify in a demo |
|---|---|---|
| Job costing | Are costs on this job tracking the estimate? | Job, phase, cost type, budget, actual, committed and forecast reports. |
| Progress billing | What can be billed this month under the contract? | Schedule of values, prior applications, approved changes, retainage and current amount due. |
| WIP | Is revenue ahead of or behind the work performed? | Cost-to-cost percentage complete, over/under billing and a ledger-posted adjustment. |
An AIA-style screen is not automatically an actual AIA G702 application with a G703 continuation sheet. Likewise, QuickBooks project profitability is not a WIP schedule. Confirm the exact output your owner, architect, lender or surety accepts.
Which software is best for each contractor profile?
1. QuickBooks Online Plus: the practical small-contractor start
Planyard describes QuickBooks Online Plus as the practical starting point for many small US contractors. Intuit’s Projects feature can assign estimates, invoices, bills, checks and expenses to a customer project and show income, expenses and profit margin. Projects are available on Plus and Advanced, not Simple Start or Essentials.
Planyard reports Intuit’s regular US prices as $38 per month for Simple Start, $85 for Essentials, $140 for Plus with five users and $340 for Advanced with 25 users. A 30-day trial is commonly offered. Payroll is extra. The lower two plans do not include Projects, so they are poor choices when job costing is the reason for buying accounting software.
QuickBooks works when one company has relatively simple invoices, limited certified or union payroll and a bookkeeper who will code every transaction. It is less suitable when the company needs native committed costs, subcontract change orders, two-sided retainage or automated certified payroll.

Intuit’s August 2026 product announcement says construction financial capabilities are included in Advanced at no additional cost. The announced bundle includes structured budgets by phase, AIA-style progress billing, change-order management and WIP over/underbilling reporting. Intuit also cautions that release dates and availability vary and that the announcement describes product direction rather than a purchase commitment.
That announcement does not confirm the depth of retainage, committed-cost tracking or certified payroll. Agenbord specifically tells buyers to test those three items. SoftwareConnect calls Advanced the only QuickBooks plan with the new construction-financial bundle, while other sources still describe Plus as adequate for basic Projects. The practical distinction is clear: Plus supplies project income, cost and margin; Advanced is the tier to investigate for phase budgets, AIA-style billing, changes and WIP.
QuickBooks Desktop Enterprise remains a Windows-oriented alternative. Planyard, citing Intuit’s October 2026 pricing page, reports Gold from $2,210 per year, Platinum from $2,717 and Diamond from $5,363 on the monthly plan, with up to 40 users on Diamond. Hosting is extra if users need access away from Windows. Desktop Enterprise has job-cost reports but the same reported gaps around committed costs and pay applications.
3. Foundation: strongest fit for certified and union payroll
Foundation is positioned as a contractor-specific accounting system for prevailing-wage, union and public-works work. Sources describe job costing, payroll, purchase orders, subcontracts, accounts receivable, AIA and time-and-materials billing, retainage, WIP and certified-payroll exports. DIR, eMars and LCPtracker formats are cited by Agenbord. It replaces the general ledger rather than sitting beside QuickBooks.

Foundation is modular and quote-only on the vendor-site checks reported by Planyard and Agenbord. SoftwareConnect prints a $400-per-month starting field, SelectHub prints $500 and Construction CFO uses $500 and up as a ballpark. Those are secondary figures, not a confirmed Foundation list price. Ask for a written first-year and renewal quote that includes payroll, mobile time, implementation, data conversion and every required module.
The trade-off is depth and learning curve. SoftwareConnect reports a steeper data-entry experience than QuickBooks, operational complaints and uneven mobile feedback, while still rating Foundation highly for small to midsize contractors with a bookkeeper or controller. The payroll and job-cost architecture is the reason to consider it, not a low headline price.
4. Sage 100 Contractor: an all-in-one installed or hosted ledger
Sage 100 Contractor combines accounting, job costing, payroll and project management for small and midsize contractors. The cited vendor positioning includes certified payroll, AIA billing, lien waivers, estimates that flow into budgets, subcontracts and purchase orders, and an optional construction-management product for field work.
Planyard reports Sage’s site as quote-only in October 2026. SoftwareConnect lists $160 per user per month, while Construction CFO cites review-platform figures of $115 per user and $150 and up. Treat all of those as secondary estimates. Sage 100 is Windows-based and can be installed on a workstation or server; remote access generally requires third-party hosting and extra cost.
This is a migration choice when payroll, pay applications and job cost have outgrown a general ledger. Implementation is heavier than adding a cloud layer, so compare the cost of conversion and training with the cost of maintaining several disconnected add-ons.
5. Sage Intacct Construction: multi-entity cloud finance and WIP
Sage Intacct Construction combines cloud financials with construction functionality for general contractors, specialty contractors, home builders, heavy civil firms and developers. The documented feature set includes actual and committed costs across labor, materials, plant, subcontractors and change orders; project and progress billing; retainage; WIP at job and sub-job level; dashboards; historical comparisons; multi-entity consolidation; and an open API.
RKL eSolutions says payroll is generally supplied through Sage HCM or ADP Workforce Now for Construction rather than being the native construction payroll engine. Agenbord and SoftwareConnect likewise describe a partner or separate license for certified or union payroll and for Sage Estimating. Confirm the payroll architecture before assuming the finance platform solves field payroll.
Pricing is quote-only. FinTruction reports reseller entry points of roughly $9,000–$12,000 per year for one user on core financials, a separate research estimate of $18,000–$32,000 per year plus $35,000–$80,000 implementation for a $10 million–$30 million contractor, and warns readers to treat any single estimate with suspicion. RKL says a basic Sage Intacct project commonly starts near $40,000 including software and implementation, with construction and real estate often higher. The price depends on modules, user levels, entities, implementation help and the client’s staff time.
RKL says focused implementations can take a couple of months, while multi-entity history, integrations and phased rollouts take longer. Suitable day-one data can include vendors, customers, employees, chart of accounts, active jobs, cost codes and types, open payables and receivables, commitments and opening balances.
6. Knowify: QuickBooks add-on for AIA pay applications
Knowify is designed for electrical, mechanical and specialty subcontractors that already use QuickBooks and need construction workflow around it. Planyard reports October 2026 annual-billing prices of $99 per month for Core and $329 for Advanced; month-to-month prices are $149 and $399, with extra users at $29 per month. Advanced includes 10 users and the job-cost and project-management tools.

The product creates G702 and G703 pay applications from a schedule of values, tracks retainage and applies change orders to the correct billing cycle. It integrates with QuickBooks Online, QuickBooks Desktop and Intuit Enterprise Suite. The QuickBooks-centered architecture means a Xero or Sage shop should not assume the same fit. SaaSrat’s May 2026 matrix marked certified payroll as unavailable and WIP percentage-of-completion as manual, so those remain demo questions.
7. Planyard: a cost-control layer, not a general ledger
Planyard publishes its own prices at $105 per project manager per month for Essential, $158 for Professional and $210 for Ultimate; estimating-only access is $52 and supporting staff are $43. A 14-day trial is listed. Essential adds job costing and QuickBooks or Xero synchronization; Professional adds purchase orders, committed costs, change orders and client progress billing; Ultimate adds subcontractor pay applications and bid requests.
Planyard says G702 and G703 forms are coming but are not available yet. Payroll remains in the accounting system. Because Planyard wrote a major October 2026 roundup used in this guide, its product descriptions and recommendations are vendor-originated and should be validated in a common demo.
8. Xero Established: a lighter ledger for a non-QuickBooks shop
Planyard, citing Xero’s US page, reports Early at $27 per month, Growing at $59 and Established at $97. Xero charges per organization rather than per user, and project time and cost tracking is on Established. Early is capped at 20 invoices and five bills per month. Payroll through Gusto is extra, from $36 per month plus $6 per employee.
Xero has no construction billing engine in the cited material. It can be a reasonable ledger when a CPA already works in Xero and a separate job-cost layer handles commitments and pay applications. It is less attractive if the goal is one native system for payroll, WIP, retainage and certified reporting.
9. Acumatica: separate APEX and Construction Edition offers
Do not combine the two offers. Agenbord, citing Acumatica, describes APEX for Construction as under $1,500 per month including implementation and support, with unlimited users and SaaS delivery, aimed at smaller construction companies. SoftwareConnect separately prints about $1,800 per month for the broader Cloud ERP, with partner estimates above $25,000 per year for midsize subscriptions and implementation around $60,000–$100,000 or more.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The broader Construction Edition is described as supporting multiple unions and locals, certified wages, lien-waiver and insurance tracking, AIA applications, WIP automation, mobile time and equipment hours, daily field reports and multi-company accounting. SoftwareConnect also reports a renewal cap of 10% per year on list price, but first-year discounts may not carry forward. Request the exact edition, transaction volume and implementation scope in writing.
What other systems belong on a shortlist?
Trimble Viewpoint Spectrum is positioned as a web-based cloud ERP for mid-to-large contractors, connecting field, service, accounting, payroll and HR, including multiple unions. Vista is aimed at larger contractors with job-cost accounting, financials, HR, service and equipment. Both are quote-only in the cited vendor checks. A SoftwareConnect page also contains a legacy $10,000 perpetual-license note; do not treat that as a current cloud subscription.
Premier Construction Software is a cloud ERP on Microsoft Azure covering accounting, job costing, project management and documents. Sources describe company- and user-based quote pricing, multi-entity consolidation, intercompany transactions, change-order automation and accounts-payable routing with commitment matching and lien-waiver automation.
TimeSuite is listed by SoftwareConnect at a $417-per-month starting price plus setup. It automates over/underbilling and keeps percentage-of-completion projection logs. ComputerEase is aimed at specialty and trade contractors and allocates one worker’s day across jobs, including union payroll. Jonas Construction provides job cost by labor, equipment, materials and subcontractors but does not publish pricing.

Procore belongs in the field-and-project layer, not as the accounting system of record. Construction CFO says its financial tools handle budgets, commitments, change events, change orders, pay applications and retention but lack a general ledger and native WIP schedule, so an ERP remains behind it.
How should you choose between two finalists?
Use the same recent job and the same data set for every finalist. A feature checklist is less useful than watching the transaction flow from field event to ledger.
- Pay application: create a bill with a schedule of values, prior billings, 10% retainage and an approved change order. Confirm the owner receivable, retainage receivable, job cost and general ledger all post together.
- Change orders: approve an owner change and the matching subcontract change without retyping. Verify that pending cost enters the forecast but not the bill until approved.
- Payment controls: submit a subcontractor pay app with a missing lien waiver. The system should block payment or require a named override with an audit trail.
- WIP close: enter the project manager’s cost-to-complete estimate, calculate percentage complete and over/under billing, then tie the journal entry to the ledger.
- Payroll: for public or union work, enter one employee across two jobs and two classifications for one week. Require the weekly certified-payroll and union output from those same timesheets.
Ask each vendor to identify what is native, what is an add-on, what is an integration and what requires manual spreadsheet work. Ask whether the output is an actual G702/G703 or merely an AIA-style report.
How much does construction accounting software cost?
Published prices cover only part of the decision. Construction CFO says 13 of 28 vendors in its comparison publish no price. Quote-only products should be compared on first-year and renewal cost for identical users, entities, payroll modules, integrations, implementation and data conversion.
For a small contractor, the known subscription floor is a general ledger such as QuickBooks Online Plus at $140 per month, possibly combined with Knowify or a cost-control layer. Foundation, Sage 100 and Sage Intacct can cost substantially more, but the sources do not support a single official list price. Sage Intacct estimates range from reseller entry points to implementation-inclusive projects near $40,000 or more; those are not Sage list prices.
Include the cost of a second legal entity, payroll, certified reports, mobile time, estimating, hosting, API connections, training, support and renewal increases. A low monthly fee can become expensive when staff must re-enter commitments, change orders and retainage in multiple systems.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When do you need a construction ERP instead of an accounting add-on?
An add-on is usually sufficient when one company has a familiar ledger, a few active jobs and a bookkeeper who can maintain the sync. Move toward a construction ERP when several companies bill one another, an equipment fleet needs costing, a service division shares resources, purchasing requires approvals, HR covers a large field workforce or a surety requires repeatable WIP across entities.
Construction ERP means project management, field data, equipment, service and document control share a database with finance. Foundation and Sage 100 sit closer to construction accounting; Sage Intacct Construction, Premier and Viewpoint products are sold as broader ERPs. Do not rebuild a general ledger, tax tables or certified payroll in custom software; integrate those functions instead.
How should you handle certified payroll?
For federally funded or assisted construction contracts over $2,000, Agenbord’s summary of US Department of Labor guidance says covered contractors and subcontractors must pay at least locally prevailing wages and fringe benefits and submit payroll information weekly with a signed statement of compliance. The optional WH-347 form does not make the weekly submission optional. State and agency formats can add requirements.
Sources identify Foundation and Sage 100 as strong native choices, with ComputerEase and Acumatica supporting multi-union crews. Sage Intacct Construction generally relies on Sage HCM or a partner for payroll. QuickBooks plus Knowify is marked as lacking certified payroll in SaaSrat’s May 2026 matrix, and nothing in Intuit’s August announcement says certified payroll was added to Advanced. Treat certified payroll as a compliance requirement, not a nice-to-have report.

How do you migrate from QuickBooks?
Cut over at a period end. January 1 is simplest for payroll because year-to-date wages for W-2s do not need to be reconstructed. Before switching, map every open job by cost code and load contract value with approved changes, budget, cost to date, billed to date and the schedule of values with prior billings.
- Rebuild retainage by job and subcontractor if the old system held it in one account.
- Load open subcontracts and purchase orders with original value, changes, invoiced-to-date, retainage and remaining balance.
- Convert receivables and payables by invoice, not as one customer or vendor balance.
- Bring vendor year-to-date payments for 1099 reporting if the switch is mid-year.
- Reconcile job-cost accounts, retainage control accounts and opening WIP to over/underbilling accounts.
- Run one month-end close in both systems and retain read-only access or an export for closed jobs.
A migration is not complete when the trial balance agrees. It is complete when an open job, commitment, pay app, retainage balance and WIP entry all reconcile to the same source data.

What are the most common implementation mistakes?
- Choosing by revenue alone: a $2 million union subcontractor may need deeper payroll than a larger company with simple time-and-materials invoices.
- Confusing AIA-style with G702/G703: ask for the actual form output and continuation-sheet behavior.
- Ignoring commitments: an invoice-only system can show a profitable job until a large subcontract bill arrives.
- Using one retainage account: owner receivable and subcontract payable need separate job-level ledgers.
- Assuming WIP equals project profitability: WIP requires a consistent cost-to-cost method, over/under accounts and a month-end journal.
- Leaving coding unreviewed: an illustrative Construction Cost Accounting example shows a $15,000 unassigned bill changing reported margin from 24.0% to 21.0% on a $500,000 contract. It is arithmetic, not a study, but it demonstrates why unassigned-transaction reports matter.
- Trusting scores as a bake-off: iTechGuides scores Sage Intacct Construction 9.4 and Foundation 8.7, but marks several job-costing, retainage, WIP and payroll cells unchecked and says paid vendors may receive fuller reviews. Those scores are not a substitute for a common demo.
How we picked
The shortlist follows the criteria the sources repeatedly identify: job, cost-code and cost-type structure; committed costs; progress billing and retainage in both directions; change-order linkage; WIP and ledger posting; certified and union payroll; multi-entity consolidation; implementation and renewal cost; and whether the product replaces or supplements the general ledger. Products are ranked by the contractor profile they serve, not by an invented market-share or accuracy score. This research found no independent census of US contractor systems and no peer-reviewed test of pay-application accuracy.
Bottom line
Start with QuickBooks Online Plus when the business is small, single-entity and lightly regulated. Evaluate Advanced if phase budgets, AIA-style billing, changes and WIP are the missing pieces, but verify retainage, commitments and certified payroll. Choose Foundation or Sage 100 when construction payroll and a contractor-native ledger are the core problem. Choose Sage Intacct Construction when a controller needs cloud WIP and multi-entity consolidation. Add Knowify or Planyard when the ledger works but pay applications and commitments do not. In every case, make the final decision from the same live-job demonstration and a written implementation quote.
Frequently Asked Questions
Is there a free construction accounting software plan?
None of the principal products in this comparison has a documented permanent free tier. QuickBooks Online commonly offers a 30-day trial, and Planyard lists a 14-day trial; quote-only systems generally begin with a sales process rather than a self-serve trial. Confirm trial data-export rights before entering real jobs.
Can construction software prepare my tax return?
It can produce job-cost, WIP and general-ledger schedules, but the accounting method used for financial statements and the tax return is a CPA decision. Ask the implementation team how WIP workpapers, retainage and change-order history can be exported for your tax preparer.
Should payroll and accounting be in the same construction system?
Keeping them together reduces duplicate job coding, but a finance platform may rely on a payroll partner for certified or union work. Compare the payroll engine, fringe calculations, state registrations, year-end forms and integration audit trail—not just whether the product has a payroll menu.
What should I demand in a construction software contract?
Request written limits for users, entities, storage, API calls, payroll employees, support response times, renewal increases, data export and termination assistance. Also require the implementation statement of work to name every converted field, open commitment, retainage balance and report your team expects at go-live.
How do I preserve an audit trail after switching systems?
Keep the old company readable or retain a complete export of closed jobs, invoices, pay applications, change orders, payroll records and approvals. Document the opening balances and the reconciliation between systems so a future auditor can trace a WIP or retainage number to its original transaction.
