# General Contractor Software That Runs the Office While You Run the Job

General contractor software keeps a construction business's leads, estimates, contracts, change orders, subcontractors, draws and job costs in one system. For small remodelers and builders, the most useful tools also answer inquiries when you're on site, keep bids from going cold and make sure every change order and progress bill actually gets invoiced and paid.

## Key takeaways

- A GC's money leaks happen between steps: unbilled change orders, late draws, missing lien waivers and sub paperwork.
- Remodel inquiries are high value but slow to close. Answering fast and following up for weeks both matter.
- BRIX answers calls, follows up bids, turns work into invoices and chases them, tracks 1099 subs and syncs with QuickBooks.
- BRIX isn't a full construction project management suite. If you need Gantt schedules, selections portals or AIA pay apps, a construction PM tool may fit better.
- Plans are month-to-month with no long-term contract.

## Why general contractors outgrow spreadsheets

General contractors outgrow spreadsheets when there are more moving parts than one person can hold in their head. A single kitchen remodel can involve a designer, a plumber, an electrician, a cabinet supplier, a countertop fabricator, a building inspector and a homeowner who changes their mind about the backsplash twice. Run four of those at once and the spreadsheet stops being the truth.

The real cost isn't the chaos itself. It's what slips through: the extra outlet the homeowner asked for that never got written up, the draw you meant to send on Friday, the sub whose insurance certificate expired last month, the bid you forgot to follow up on that went to someone else.

## A remodel from first call to final payment

Here's how a typical residential remodel moves, where it usually goes wrong, and which part of BRIX picks it up. The numbers are illustrative.

1. **The inquiry.** A homeowner calls about a $60,000 kitchen while you're on a job site. Without a system it's a voicemail you return tomorrow. With BRIX, the [AI receptionist](https://www.brix.so/features/ai-receptionist) answers, asks about scope, budget range and timeline, and books the site visit.
2. **The site visit and estimate.** You measure, talk through options and build the estimate. [Quotes and estimates](https://www.brix.so/features/quotes-estimates) helps you build it and keeps it on the customer's record.
3. **The waiting.** The homeowners are getting three bids and talking to the bank. This is where most small GCs lose jobs. [Sales automation](https://www.brix.so/features/sales-automation) follows up by text and email on a schedule so you don't have to remember.
4. **Contract and deposit.** They sign. The deposit invoice goes out and gets chased through [invoicing and payments](https://www.brix.so/features/invoicing-payments). Deposit limits on home improvement contracts vary by state; see [contractor deposit laws](https://www.brix.so/learn/contractor-deposit-laws).
5. **Change orders.** Mid-demo, they want the wall moved. Write it up and get it signed before the work, then invoice it. More on this below.
6. **Progress draws.** Each milestone (rough-in, drywall, cabinets, final) becomes an invoice. BRIX chases unpaid ones politely until the money lands.
7. **Punch list and closeout.** Finish the [punch list](https://www.brix.so/learn/punch-list), collect the final payment, release or collect lien waivers, and ask for a review. [Review requests](https://www.brix.so/features/reviews-reputation) go out automatically after the job.

## Which back-office jobs does BRIX take off a GC's plate?

BRIX handles the calls, follow-up, invoicing, payment chasing, sub payment tracking and QuickBooks sync. It doesn't replace your estimating spreadsheet's construction logic or produce AIA pay applications. Here's the honest breakdown against the work a GC's office actually does:

**General contractor back office vs. BRIX**

| Back-office job | Covered by BRIX? | How |
| --- | --- | --- |
| Job costing | Partly | Invoices and payments sync to QuickBooks and expenses stay categorized, so job costs in QuickBooks stay current. See [job costing](https://www.brix.so/learn/job-costing). |
| Progress billing / AIA | Progress invoices, yes. AIA G702/G703 forms, no | Each draw becomes an invoice that gets chased until paid. See [progress billing](https://www.brix.so/learn/progress-billing) and [AIA billing](https://www.brix.so/learn/aia-billing). |
| Change orders | Invoicing, yes | Approved change work becomes an invoice like any other. Use a written change order form; see [change order](https://www.brix.so/learn/change-order). |
| Retainage | Tracking the open balance | Retained amounts stay on the books as unpaid until released. See [retainage](https://www.brix.so/learn/retainage). |
| Sub 1099s and COIs | 1099 tracking, yes; licenses and documents, yes | Payments to 1099 subs are tracked all year; compliance tracking flags license and document renewals before they lapse. |
| WIP reporting | No | Your accountant or a construction accounting tool builds the [WIP report](https://www.brix.so/learn/wip-report); BRIX keeps the invoice and payment data clean for it. |

## What a remodel inquiry call sounds like

This is a sample call written to show how BRIX handles a remodeling inquiry. It isn't a recording of a real customer. The company is a placeholder, and you decide during setup what the AI asks, including whether it asks about budget.

**Sample call: bathroom remodel inquiry**



**AI receptionist:** Thanks for calling Sample Builders. How can I help?

**Caller:** We want to redo our primary bathroom. Tub out, walk-in shower in. Do you do that?

**AI receptionist:** We do. What's the address, so I can confirm it's in our service area?

**Caller:** 77 Larkspur Lane.

**AI receptionist:** That's in our area. Are you thinking of keeping the layout the same, or moving plumbing around?

**Caller:** Probably moving the toilet. The current layout is awkward.

**AI receptionist:** Got it. Do you have a timeline in mind, and a rough budget range you're working with? It helps our estimator bring the right options.

**Caller:** We'd like it done before the holidays. Budget, maybe 30 to 40 thousand?

**AI receptionist:** Thanks. Our project manager can come out for a walkthrough Tuesday at 5 p.m. or Saturday at 10 a.m. Which works better?

**Caller:** Saturday.

**AI receptionist:** You're booked Saturday at 10 a.m. at 77 Larkspur Lane. I'll text a confirmation. Can I get your name and email for the estimate?

The AI filtered for service area, captured scope, timeline and budget, and booked a walkthrough with someone who's ready for that conversation. More examples, including sub and supplier calls, are on [AI receptionist for general contractors](https://www.brix.so/for/general-contractor/ai-receptionist).

## How should a GC handle change orders?

Handle every change order the same way: write it, price it, get it signed and invoice it, before the work starts. Verbal changes are the single most common way GCs give away margin, because "while you're in there" work gets done in good faith and argued about at the final payment.

1. **Write it down the same day,** even if it's small. Scope, price, schedule impact.
2. **Get a signature or written approval** before the crew touches it.
3. **Invoice it** on the next draw or as its own invoice, so it doesn't vanish into the final.
4. **Keep it on the customer record** with the original contract, so the final reconciliation is easy.

Our [change order](https://www.brix.so/learn/change-order) and [scope of work](https://www.brix.so/learn/scope-of-work) guides cover what to include. A change order template is coming to the templates section.

## Subs, 1099s, insurance certificates and lien waivers

A GC's sub paperwork protects you from three expensive surprises: a tax mess at year-end, an uninsured sub getting hurt on your job, and a lien on the homeowner's house from a supplier you already paid through the sub.

- **W-9 before the first payment.** For payments made after Dec. 31, 2025, the IRS 1099-NEC threshold is $2,000 per payee per year (it was $600 for 2025 payments). See [1099 for subcontractors](https://www.brix.so/learn/1099-for-subcontractors) and [W-9 for subcontractors](https://www.brix.so/learn/w9-for-subcontractors).
- **Certificates of insurance on file and current.** See [certificate of insurance](https://www.brix.so/learn/certificate-of-insurance) and [general liability insurance](https://www.brix.so/learn/general-liability-insurance).
- **Lien waivers with every payment.** Conditional when you pay, unconditional once the money clears. Forms and rules vary by state; see [lien waiver](https://www.brix.so/learn/lien-waiver) and [mechanic's lien](https://www.brix.so/learn/mechanics-lien).
- **Licenses current.** See [contractor license](https://www.brix.so/learn/contractor-license).

BRIX tracks payments to 1099 subcontractors through the year and its compliance tracking watches licenses, safety documents and permits and flags renewals before they lapse.

## The general contractor's year

General contracting runs year-round, but demand isn't flat. Many homeowners start planning remodels in late winter and want work started in spring, which makes early spring the busiest time for inquiries and estimates in a lot of markets.

**Seasonal rhythm for a residential GC (varies by climate)**

| When | What's happening | What to automate |
| --- | --- | --- |
| January–March | Planning season; inquiries and estimate requests climb | Answer every inquiry, book walkthroughs, follow up every bid |
| April–June | Spring booking surge; exterior work and additions start | Deposit and draw invoices, crew scheduling, sub payment tracking |
| July–September | Peak production; homeowners want projects done before the holidays | Change order invoicing, payment chasing, review requests at closeout |
| October–December | Interior projects, holiday deadlines, year-end | 1099 prep, final draws, quarterly tax reminders |

## BRIX vs. Buildertrend and JobTread

Buildertrend and JobTread are construction management platforms built for builders and remodelers. They're strong on things BRIX doesn't try to do: detailed construction schedules, budgets, selections, client portals and project documentation. If your main need is project management on complex builds, they may be the better fit.

**GC software at a glance**

|  | BRIX | Buildertrend | JobTread |
| --- | --- | --- | --- |
| Built for | Blue collar businesses that need the office handled | Builders and remodelers (construction PM) | Contractors including builders and remodelers |
| Pricing | Month-to-month, no long-term contract | Custom quote | $199/month plus $20 per internal user (monthly plan); no contract |
| Answers your phone | Yes, AI receptionist | No | No |
| Estimate follow-up | Automatic text and email | See vendor | See vendor |
| QuickBooks | Sync with QuickBooks | QuickBooks, Xero, Gusto | QuickBooks Online integration |
| Construction schedules and selections | No | Yes | Yes |

_Buildertrend from its pricing page as of 2026-10-12; JobTread from its pricing page as of 2026-10-19. Check current pricing before you decide._

Some GCs run both: a construction PM tool for the build, and BRIX for the phones, follow-up, invoicing and books. If you're a smaller remodeler whose real problem is missed calls and unbilled work, BRIX alone may cover it.

## Is BRIX a fit for your contracting business?

- **Good fit:** residential remodelers and small builders running a handful of projects at once, where the owner is on site, inquiries go to voicemail, bids go cold and draws go out late.
- **Good fit:** GCs who already like QuickBooks and want invoices, payments and sub payments landing there without retyping.
- **Maybe pair with a PM tool:** builders managing detailed schedules, selections and client portals across many jobs.
- **Not the right tool alone:** commercial GCs whose owners require AIA pay applications as the core billing workflow.

BRIX answers remodel inquiries 24/7 and books walkthroughs, follows up every open bid, turns deposits, draws and change orders into invoices and chases them, tracks 1099 subs and license renewals, and keeps QuickBooks in sync. Month-to-month, set up for your business.

- [AI receptionist](https://www.brix.so/features/ai-receptionist): Answers every call 24/7, qualifies the caller, books the job and texts back anyone it misses.
- [Sales automation](https://www.brix.so/features/sales-automation): Follows up every lead and open estimate automatically by text and email, and asks every customer for a review after the job.
- [Invoicing and payments](https://www.brix.so/features/invoicing-payments): Turns finished jobs into invoices and politely chases unpaid ones until the money is in your account.
- [Bookkeeping and tax help](https://www.brix.so/features/bookkeeping-taxes): Keeps expenses categorized, tracks 1099 subcontractors and sales tax, and reminds you of quarterly estimated tax dates. BRIX does not file taxes or give tax advice.
- [Compliance and permit tracking](https://www.brix.so/#use-cases): Tracks licenses, safety documents and permits and flags renewals before they lapse.
- [QuickBooks sync](https://www.brix.so/integrations/quickbooks): Syncs customers, invoices and payments with QuickBooks so the books match the jobs.

## Frequently asked questions

### What is the best software for a small general contractor?

Pick for your biggest bottleneck. If it's managing complex builds (schedules, selections, budgets), construction PM tools like Buildertrend or JobTread are built for that. If it's missed inquiries, cold bids and unbilled change orders, a system like BRIX that answers calls, follows up and invoices may matter more.

### Do general contractors need a CRM?

Most do once they're bidding more than a few jobs a month. Remodel sales cycles are long, and without a CRM, follow-ups depend on memory. A CRM keeps every inquiry, estimate, call and invoice on one customer record.

### Does BRIX do AIA billing?

BRIX turns each progress draw into an invoice and chases it until paid. It doesn't generate AIA G702/G703 pay application forms. If your commercial clients require AIA pay apps, you'll need a tool or accountant that produces them.

### Can BRIX track subcontractor insurance and licenses?

BRIX's compliance tracking watches licenses, safety documents and permits and flags renewals before they lapse, and it tracks payments to 1099 subs. Confirm on your setup call how you want sub certificates of insurance handled.

### Does BRIX replace Buildertrend or JobTread?

Not for detailed construction project management. BRIX covers the office side: calls, follow-up, invoicing, payment chasing, 1099 tracking and QuickBooks. Some GCs use both; smaller remodelers often only need the office side.

### How much does general contractor software cost?

It ranges widely. JobTread lists $199 a month plus $20 per internal user on its monthly plan (checked 2026-10-19), while Buildertrend quotes custom pricing. BRIX is month-to-month with no long-term contract and is priced after a short call because it's set up per business.

### Can the AI receptionist screen out tire-kickers?

It can ask the qualifying questions you choose, like service area, scope, timeline and budget range, before booking a walkthrough. You decide during setup which answers get a visit and which get a polite follow-up instead.
