The Best Construction Invoice Software (2026)

"Construction invoice software" describes two completely different products, and which one you need depends on which direction the invoice is travelling.

If you are a subcontractor trying to bill a general contractor, you need progress billing: a schedule of values, retainage, stored materials, lien waivers, and submission into whichever portal that GC mandates. If you are a contractor drowning in supply-house invoices, you need accounts payable: extraction, job costing, approval, payment, and ideally some check on whether the prices were right.

Almost nothing serves both. Almost every guide to this topic mixes them together.

This one separates them.

Two disclosures. We build CostCrunch, which is on the receiving side, so weigh that section accordingly. On pricing: published prices are stated with the note that they were current at our last check; where a vendor does not publish, this guide says so.

Which half do you need?

If you are both — and most contractors are — you need one product from each half. They do not consolidate, and a tool claiming to do both usually does one properly.

Part one: software for the invoices you send

The billing side, which is where subcontractors feel the most pain and where the software market is thinnest.

What makes construction billing hard

A construction invoice is not an invoice. It is a pay application, and it carries:

• A schedule of values — the job broken into line items, each with a contract value, prior billings, and work completed this period
• Retainage, typically 5-10%, withheld and released on its own schedule
• Stored materials, billed before installation under specific documentation rules
• Lien waivers, conditional and unconditional, from you and frequently from your own suppliers and subs
• Compliance documents — insurance certificates, certified payroll on public work
• A submission format and calendar set by the customer, not by you

And the format is different for every general contractor you work for. One wants AIA G702 and G703 as a PDF by the 25th. One wants it in Textura. One wants it in GCPay. One has a spreadsheet template with its own line numbering.

That variety is the actual problem. The billing arithmetic is straightforward; reproducing it correctly across six different customer formats every month is what consumes a billing person's life.

The options

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

Where it's strong. It is the only significant product designed around the sub's side of this problem rather than the GC's, and portal integration is the specific thing that removes the manual re-entry. It also tracks waiver and compliance status, which is where pay apps actually get rejected.

Where it falls down. Not published pricing, so budget through a sales conversation. It is a billing tool, not an accounting system — it sits alongside your ERP rather than replacing it, which means another integration to maintain. And it only helps with the customers whose portals it supports; a GC with a bespoke spreadsheet template is still a manual job.

GCPay (an Autodesk company) and Oracle Textura are the platforms on the other side of the transaction — GCs use them to collect sub invoices and compliance documents. As a sub you do not choose these, you comply with them. As a GC, they are how you industrialize sub payment and waiver collection. Neither publishes pricing.

Knowify handles AIA billing and change orders alongside job costing for small-to-mid commercial subs, syncing to QuickBooks. It is a reasonable answer when you want progress billing without either a full ERP or a dedicated billing tool. Pricing is not published on the vendor site.

Construction ERPs — Sage 100 Contractor, Foundation, Sage 300 CRE, Viewpoint Vista — all include AIA billing natively. If you already run one, you may not need a separate billing product; what you may still need is portal submission, which is the gap Siteline fills. None publish pricing.

QuickBooks Online publishes pricing at $38 to $340 per month by tier following the August 2026 increase, and does not do AIA progress billing, retainage, or certified payroll. Contractors build these in spreadsheets, which works until it doesn't.

The honest recommendation for the sending side

If you bill fewer than roughly three GCs, spreadsheets plus your accounting system are survivable. If you bill six GCs across four different portals, the billing person is the bottleneck and the software pays for itself in avoided billing-cycle delays rather than in hours saved. A pay application rejected on a technicality costs you 30 days of cash on that amount, which dwarfs any efficiency argument.

Part two: software for the invoices you receive

This half is covered in depth in our construction AP automation guide, so what follows is the shape of the decision rather than a full roundup.

The requirement that separates the market

Line-item coding with job, cost code, and phase, not bill-level posting. A supply-house invoice covering six jobs must split six ways, or your job costing is approximate and cannot be used to bid the next one.

Then, in order: retainage on subcontract invoices, lien waivers collected before payment, subcontractor compliance verified at each payment event, intake of messy documents, and a workable model for the substantial share of invoices that never had a purchase order.

The options in brief

AvidXchange for mid-market firms on Sage 300 CRE or Viewpoint with lien waiver obligations. Stampli where approval delay is the bottleneck. Field Materials if procurement and AP are one problem. MakersHub for construction-native line-item AP without a procurement platform. All quote-only.

Ramp and BILL publish pricing, pay vendors well, and are not job-cost aware — reviewers specifically note BILL syncs at the bill level without committed costs, percentage-of-completion, or cost-to-complete. Dext publishes pricing and captures documents into QuickBooks without approvals or payments.

The volume threshold where automation pays for itself sits around 200 vendor invoices a month, per construction AP buyer guidance, with manual entry consuming 20 to 40 hours monthly per AP clerk.

The question none of them answer

Every product on the receiving side validates the invoice against your own paperwork — the purchase order, the receiving record, the contract. That is three-way matching, and it catches quantity errors, duplicate billing, and substitutions.

It cannot tell you the price was too high. If the PO said $18.40 and the invoice says $18.40, the match is clean regardless of whether $18.40 was competitive in your market that month. Every document agrees. You still overpaid.

That is a separate product category, and it is where we sit.

Where CostCrunch fits — and where it doesn't

We build CostCrunch, so treat this accordingly.

We are entirely on the receiving side. We do not do progress billing, pay applications, schedules of values, retainage, or lien waivers — nothing in Part One of this guide. If your problem is billing your GCs, Siteline or your ERP is the answer and nothing we do helps.

On the receiving side: you forward material and supply invoices to an email address, every line item is extracted at 99% accuracy, and each is checked against your own purchase history and local market rates. Overcharges, duplicate charges, quantity errors, and gradual price creep are flagged before you approve, and verified line-item data syncs to QuickBooks, Sage, or FreshBooks with job and cost-code assignment.

Where it falls down. We do not pay your vendors — no ACH, no checks, no cards — so if payment execution is what you want, run us alongside a tool that does it. We are material-invoice focused rather than a system for all payables including rent and insurance. And our market benchmark is strongest where we have depth of comparable transactions; on unusual or custom material it is thinner.

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.

How to choose

1. Establish which direction your problem points. Sending or receiving. Most guides to this topic will not do this for you, and it is the entire decision.

2. On the sending side, count your customers' portals. That number, not your revenue, determines whether billing software pays for itself.

3. On the receiving side, count your monthly invoices. Under 200, a bookkeeper is often cheaper than software.

4. Check whether your ERP already does it. Construction ERPs include AIA billing. Buying a billing tool when the capability is already licensed is a common waste; the gap is usually portal submission, not the billing itself.

5. Do not expect one product to cover both. Sending and receiving are different problems with different data models, and a product claiming both usually does one properly.

Questions to ask on every demo

• Which of my customers' billing portals do you submit into directly?
• Does it track conditional and unconditional waivers, from me and from my suppliers?
• On the receiving side: line-item detail with job and cost code, or one bill-level entry?
• How does it handle an invoice with no purchase order?
• What does your price checking compare against — my PO, my history, or external market data?

Frequently asked questions

What is construction invoice software?

The term covers two unrelated categories. On the outbound side it means progress billing and pay application software — building an AIA pay application against a schedule of values, handling retainage and stored materials, collecting lien waivers, and submitting into a general contractor's portal. On the inbound side it means accounts payable automation — extracting supply-house and subcontractor invoices, coding them to jobs and cost codes, routing approvals, and paying them. The products are different, and which one you need depends entirely on which direction your invoices travel.

What is the best invoicing software for subcontractors?

For billing general contractors, Siteline is the main product built specifically for trade contractor pay applications, with integrations into the Textura and GCPay portals many GCs require. Construction ERPs including Sage 100 Contractor, Foundation, Sage 300 CRE, and Viewpoint Vista include AIA billing natively, so if you already run one the gap may only be portal submission. Knowify handles AIA billing alongside job costing for smaller commercial subs and syncs to QuickBooks. None of these publish pricing.

Can QuickBooks handle construction progress billing?

Not properly. QuickBooks Online, priced from $38 to $340 per month by tier as of August 2026, does not provide AIA progress billing, retainage tracking, or certified payroll. Contractors commonly build pay applications in spreadsheets alongside QuickBooks, which works at low volume and becomes a liability as the number of general contractors and billing formats grows. The usual upgrade paths are Knowify alongside QuickBooks, or a construction ERP that includes AIA billing natively.

What is the difference between AP automation and invoice auditing?

AP automation reads invoices, codes them, routes approvals, and pays them, verifying each invoice against your purchase order and receiving record. Invoice auditing asks whether the prices themselves were reasonable, comparing them against purchase history and external market rates. They catch different problems: matching finds quantity errors, duplicate billing, and substitutions, while auditing finds unit prices above market and gradual price creep. An invoice can pass matching perfectly while the price on the purchase order was well above market.

Why do pay applications get rejected?

Usually on documentation rather than arithmetic: a missing or incorrectly executed lien waiver, an expired insurance certificate, certified payroll not attached on public work, stored materials billed without the required documentation, a schedule-of-values line that does not match the general contractor's numbering, or submission after the customer's cutoff date. Each rejection typically costs a full billing cycle, which is why compliance tracking matters more than billing speed and why the software case rests on avoided delay rather than hours saved.

Do I need separate software for sending and receiving invoices?

Almost always yes. The two sides have different data models — a pay application is a position against a contract schedule of values, while a payable is a document to be coded and paid — and different failure modes. Products claiming to do both generally do one well. Most contractors end up with a billing solution, either their ERP or a dedicated tool such as Siteline, plus an AP solution appropriate to their invoice volume and accounting system.

How much does construction invoice software cost?

On the sending side, Siteline, GCPay, and Textura do not publish pricing, and construction ERPs that include AIA billing do not either. On the receiving side, Ramp, BILL, and Dext publish pricing, with Ramp offering a free tier, while AvidXchange, Stampli, Field Materials, and MakersHub quote after a demo with implementation on top. QuickBooks Online publishes at $38 to $340 monthly but does not cover construction billing. Compare all-in first-year cost including implementation rather than the advertised seat price.

What should a general contractor use to collect subcontractor invoices?

GCPay, now an Autodesk company, and Oracle Textura are the established platforms for collecting subcontractor pay applications along with lien waivers and compliance documents, industrializing a process that otherwise runs on email and spreadsheets. Neither publishes pricing. On the payables side, AvidXchange is the most construction-verticalized AP incumbent and includes lien waiver management in the payment workflow, which is the requirement horizontal AP tools have no model for.

The reason this category confuses people is that the industry uses one phrase for two jobs, and vendors on both sides have an interest in the ambiguity. A billing product and an AP product are as different as a cash register and a purchasing department.
