Construction business accounting software for small and new firms: when to leave spreadsheets, a 30-day setup checklist, real costs and when to upgrade.

If you run a small crew and your books live in a spreadsheet, a shoebox of receipts and your own memory, this guide is for you. Picking construction business accounting software is not about finding the most powerful system on the market. It is about finding the one you will actually keep up with every week, that tells you which jobs make money, and that your bookkeeper and CPA can work in without charging you to clean it up.
I owned three restoration companies over 14 years. The first one ran on a spreadsheet and a checkbook for longer than I like to admit, and I did not know which jobs were profitable until tax time.
This post covers the small and new construction business: how to know you have outgrown spreadsheets, what to set up in your first month, what it really costs, which tools fit a small firm, and the signs it is time to upgrade. If you already run QuickBooks and want the detailed setup, our QuickBooks for contractors setup guide goes deeper on job costing.
KEY TAKEAWAYS
Strip away the marketing and every accounting system does the same core work: it keeps a general ledger, tracks what customers owe you (receivables), tracks what you owe vendors and subs (payables), reconciles your bank and card accounts, and produces a profit and loss statement and balance sheet. Your CPA needs all of that to file your taxes.
What makes it construction business accounting software is the job layer on top. A construction business does not sell one product. It sells hundreds of different jobs, each with its own price, labor, materials, subs and change orders. So the questions you need answered are about jobs:
A spreadsheet can answer those questions for a handful of jobs. It falls apart when you have a dozen open jobs, two people entering data and receipts arriving from three trucks. For more on how receivables work on the construction side, see our guide to construction accounts receivable.
Spreadsheets are fine for your first few jobs. Nobody needs a construction ERP to build one deck. If three or more of these sound familiar, it is time:
| 1 | You find out job profit at tax time. If your CPA is the first person to tell you whether last year was good, you are flying blind on every bid you write. |
| 2 | Receipts pile up in the truck. Materials bought on the company card never get tied to a job, so job costs are always understated. |
| 3 | You cannot answer "who owes us?" in under a minute. If the answer needs a search through email and texts, invoices are already slipping. Our aging report guide explains what that answer should look like. |
| 4 | Two people keep two versions of the truth. The office has one spreadsheet, the owner has another, and neither matches the bank. |
| 5 | Payroll and job hours do not connect. You pay people, but you do not know which job their hours belong to, so labor (usually your biggest cost) never lands on the job. |
For a small or new construction business, the real choice is usually between three paths. The table below sums them up, and the cards after it cover the specific tools I would look at first. Prices are listed only where I could confirm them on the vendor's own site.
| Path | Good fit for | Watch out for |
|---|---|---|
| General ledger with project tracking (for example QuickBooks Online Plus) | Owner-operators and crews of roughly 1 to 15 doing residential, service or small commercial work | Not built for AIA billing, retainage or certified payroll out of the box. Needs discipline to tag every cost to a job. |
| General ledger plus a construction add-on (for example QuickBooks Online with Knowify) | Growing firms that bill in progress, need a schedule of values or want stronger job costing without leaving QuickBooks | Two systems to keep in sync. Decide which one is the source of truth for invoices. |
| Construction-specific accounting (for example Sage 100 Contractor or FOUNDATION) | Firms with bonded work, union or prevailing wage payroll, retainage on most jobs, or a full-time accountant | Higher cost, longer setup and more training. Overkill for most firms under a few people in the office. |
QUICKBOOKS ONLINE
Who it fits: most new and small construction businesses. It is what most bookkeepers and CPAs already know, which matters more than people think.
As listed on Intuit's pricing page in November 2026, QuickBooks Online Simple Start is $38/month (1 user), Essentials $85/month (3 users), Plus $140/month (5 users) and Advanced $340/month (25 users), before any promotional discount. Intuit lists project profitability tracking on Plus and Advanced, and its help articles describe the Projects feature as a Plus and Advanced feature. Progress invoicing (billing part of an estimate as work is completed) is turned on in the sales settings.
My take: if you want job costing, Plus is the floor. Simple Start and Essentials will keep your books, but they will not tell you which jobs make money.
KNOWIFY (ADD-ON FOR QUICKBOOKS)
Who it fits: small contractors who bill in stages or on AIA pay apps and want to keep QuickBooks Online as the ledger.
As listed on Knowify's pricing page in November 2026, the Core plan is $99/month billed yearly or $149/month billed monthly for 1 user, and Advanced is $329/month billed yearly or $399/month billed monthly for 10 users. Knowify lists AIA billing (G702/G703) with retainage tracking and QuickBooks Online sync on all plans, and job costing on Advanced and Enterprise, not Core.
My take: a sensible middle step when QuickBooks alone stops handling your billing. Check which plan includes the features you actually need before signing up.
SAGE 100 CONTRACTOR AND FOUNDATION
Who they fit: small to mid-sized contractors who need true construction accounting: job cost with cost codes, retainage, certified payroll, and the WIP reporting bonding companies ask for. Sage positions Sage 100 Contractor for small to mid-sized contractors, and reviewers note it is traditionally an on-premises product. Foundation Software offers FOUNDATION with a cloud (SaaS) deployment and aims it at trade contractors.
My take: these are where you go when you have outgrown QuickBooks, not where you start. Both quote pricing through sales, so ask for the total first-year cost including setup, training and data conversion.
Tip: Ask your CPA or bookkeeper which system they work in before you pick one. A tool they already know means cheaper cleanups, faster year-end and fewer "what is this account?" emails.
Most of the pain in small contractor books comes from setup, not the software. Skip these steps and you will pay a bookkeeper to undo it later.
| 1 | Separate business and personal money. Open a business checking account and a business card, and run every job expense through them. Mixing personal and business spending is the single fastest way to make your books useless. |
| 2 | Pick a start date and enter opening balances. Choose a clean date (the first of a month or quarter), and enter bank balances, open invoices customers owe you and open bills you owe as of that date. Do not try to re-enter three years of history. |
| 3 | Build a short chart of accounts. Separate cost of goods sold (job costs: materials, subs, direct labor, equipment rental, permits) from overhead (office rent, insurance, trucks, phones). Keep it short. Twenty sensible accounts beat eighty confusing ones. |
| 4 | Set up customers and jobs the same way every time. One customer record, one project or job per contract. Use a consistent name like "Miller, 412 Oak Hollow, Kitchen" so anyone can find it. |
| 5 | Decide your cost codes. Start with five to eight cost types (labor, materials, subs, equipment, permits and fees, other). You can add detail later. You cannot easily go back and recode a year of costs. |
| 6 | Connect bank and card feeds. Let the software pull transactions in daily. Your job becomes reviewing and coding them, not typing them. |
| 7 | Connect payroll and time tracking. Labor is usually the biggest job cost. Make sure hours are logged against jobs so wages land on the right job, not just in a payroll expense account. |
| 8 | Collect a W-9 from every sub before the first payment. Mark subs as 1099 vendors in the software. For payments made in 2026, the 1099-NEC reporting threshold rose from $600 to $2,000 per payee under the One Big Beautiful Bill Act. Your CPA will confirm what applies to your filings. |
| 9 | Set your invoice terms and template. Put the job address, invoice number, due date and payment options on every invoice. Our post on payment terms that get contractors paid covers the wording. |
The subscription is the number everyone looks at. It is rarely the biggest number. Here is what a small construction business should budget for in year one. I have only put dollar figures where the vendor publishes them.
| Cost | What it covers | How to estimate it |
|---|---|---|
| Accounting subscription | The ledger itself | QuickBooks Online Plus is $140/month as listed on Intuit in November 2026. Construction-specific systems quote through sales. |
| Payroll | Paychecks, payroll tax filings, W-2s | Usually a separate add-on or provider, priced per month plus per employee. Get a quote. |
| Payment processing | Card and ACH payments from customers | Per-transaction fees set by your processor. Check the current rates before you set your terms. |
| Add-ons | Time tracking, estimating, progress billing, receipt capture | Each tool has its own subscription. Add only what solves a real problem. |
| Setup and cleanup | Chart of accounts, opening balances, bank feeds, training | A bookkeeper's hours. Ask for a fixed quote for setup, then a monthly rate. |
| Your time | Weekly coding, invoicing, follow-up | Plan on a few hours a week. If nobody owns it, the software will not save you. |
The cost I wish someone had warned me about is the cost of doing nothing. Every month you run without job costing is a month of bids priced on gut feel. And every invoice that sits unpaid is a loan you made to your customer for free. Our post on how to collect unpaid construction invoices covers what to do once that happens.
Software only helps if someone feeds it. For a small firm, this routine takes a few hours a week and keeps the books useful year-round.
| When | Task |
|---|---|
| Every week | Code new bank and card transactions to jobs. Snap and attach receipts. Send invoices for completed work or progress stages. Review who owes you and follow up. |
| Every month | Reconcile every bank and card account to the statement. Review job profitability for open jobs. Pay bills and file sales tax if your state requires it. Send the month's numbers to your bookkeeper or CPA. |
| Every year | Send 1099s to subs, close the year with your CPA, and archive records. |
On record keeping: the IRS says to keep records supporting your tax return generally for at least three years, and employment tax records for at least four years after the tax is due or paid, whichever is later. Storing receipts and documents in your accounting software makes that easy. Good documentation also helps when a customer disputes an invoice, which we cover in bulletproof documentation for contractors.
Bring one overdue invoice.
We'll show you how AR Workflow would follow up on it from QuickBooks Online, and what your customer would see.
The right first system is not the right system forever. I would not move off QuickBooks because of size alone. I would move when the work itself demands features it does not have. These are the triggers I watch for:
| Trigger | Why it matters | What to look for next |
|---|---|---|
| AIA pay apps and schedules of values | GCs and commercial owners want G702/G703-style billing, not a simple invoice | A progress billing add-on or construction-specific system |
| Retainage on most jobs | You need to track retainage receivable per job and bill it at closeout | Retainage tracking on invoices and in aging |
| Bonding or bank requests for a WIP schedule | Sureties and lenders want percent-complete reporting and over/under billing | Built-in WIP and percent-of-completion reporting |
| Certified or prevailing wage payroll | Public work requires certified payroll reports | Construction payroll with certified reporting |
| Union payroll or multiple states | Fringe benefits, multiple rates and multi-state taxes get complicated fast | Construction-specific payroll |
| Committed cost tracking | You need to see subcontracts and POs before the bills arrive | Purchase orders and subcontract management tied to job cost |
Here is something nobody tells you when you buy construction business accounting software: it will record that a customer owes you money, and it will show you an aging report. It will not chase the customer. Someone still has to send the second reminder, text the homeowner, call the property manager and write down what they promised.
In my companies, that someone was usually me, at night, after I was done on job sites. That is the gap AR Workflow was built for. To be clear about what it is and is not: AR Workflow is not accounting software, not a general ledger and not an accounts payable tool. Your accounting system stays the source of truth. AR Workflow is the receivables layer that sits next to QuickBooks Online and handles the follow-up.
If your customers are mostly homeowners and small businesses, see how it works for QuickBooks collections, or read about construction accounts receivable software and contractor payments. For the difference between the two sides of the ledger, see accounts payable vs. accounts receivable.
For most small and new construction businesses, QuickBooks Online Plus is the practical starting point, because it includes project profitability tracking and most bookkeepers already know it. Add a construction tool like Knowify when you need AIA billing or stronger job costing, and move to a construction-specific system like Sage 100 Contractor or FOUNDATION when you need certified payroll, retainage on most jobs or WIP reporting.
General software works for most small residential and service contractors, as long as it supports projects or jobs and you set it up properly. You need construction-specific software when your contracts require progress billing with a schedule of values, retainage, certified payroll or percent-of-completion reporting.
Budget for the subscription plus payroll, payment processing fees, any add-ons and a bookkeeper for setup. As listed on Intuit in November 2026, QuickBooks Online Plus is $140/month before discounts. Construction-specific systems are quoted, so ask for the full first-year cost including setup and training.
Many owners do the weekly coding and invoicing themselves and pay a bookkeeper for monthly reconciliation and cleanup. If you are on job sites all day and the books keep falling behind, hand it off sooner. A bookkeeper who knows construction is worth more than one who does not.
It helps you invoice faster and see who owes you. Getting paid still depends on consistent follow-up. That is why many contractors pair their accounting system with a receivables tool that handles reminders, texts and payment links.
