# Contractor invoicing software that sends the invoice and chases the money

Contractor invoicing software turns a finished job into an invoice, sends it to the customer and tracks it until it's paid. BRIX creates the invoice from the completed job, politely chases unpaid invoices with automatic reminders until the money is in your account, and syncs invoices and payments to QuickBooks so your books match your jobs.

## Key takeaways

- The fastest way to get paid is to invoice the day the job is done, not at the end of the week.
- Most late invoices aren't disputes. They're forgotten. A polite reminder schedule fixes most of them.
- BRIX turns finished jobs into invoices and follows up on unpaid ones automatically.
- Invoices and payments sync to QuickBooks, so nobody re-enters them and reconciliation is quicker.

## What does contractor invoicing software do?

Contractor invoicing software creates invoices from jobs, sends them by email or text, records payments and shows who still owes you. The better tools also send reminders automatically and push the invoice and payment into your accounting software. That last part matters more than it sounds: an invoice that lives in one app and a payment that lives in another is how books drift out of sync.

For most trades owners, invoicing isn't hard. It's just late. You finish a job at 5 p.m., you're on the next one at 7 a.m., and the invoice waits for Sunday night. Every day it waits is a day the customer hasn't even been asked to pay.

## Why do contractors get paid late?

Contractors usually get paid late for three reasons: the invoice goes out late, nobody follows up when it's past due, and the invoice is unclear enough that the customer sets it aside. Very few late invoices are true disputes. Fix the process and most of the money shows up on its own.

- **Invoicing in batches.** Saving invoices for Friday adds days to every payment before the customer has seen a bill.
- **No reminder schedule.** Owners hate chasing money, so they don't, and the invoice slides to 60 days.
- **Vague invoices.** "Service call, $640" invites a phone call. Line items with what was done get paid.
- **Too few ways to pay.** If the only option is a mailed check, expect to wait for the mail.
- **No deposit on big jobs.** Without a deposit or [progress billing](https://www.brix.so/learn/progress-billing), you're financing the customer's project.

> **Illustrative example: what slow invoicing does to cash**
>
> Say an HVAC shop bills $60,000 a month and customers pay, on average, 40 days after the job.
>
> That's roughly $80,000 sitting in [accounts receivable](https://www.brix.so/learn/accounts-receivable) at any time ($60,000 × 40 ÷ 30).
>
> Cut that to 20 days by invoicing same day and reminding on schedule, and about $40,000 moves from customers' pockets into your bank account. These are example numbers; check your own with the [DSO calculator](https://www.brix.so/tools/dso-calculator).

**Days sales outstanding**

```
DSO = (Accounts receivable ÷ Credit sales for the period) × Days in the period
```

Where:
- Accounts receivable = what customers owe you today
- Credit sales = invoiced sales for the period, not cash paid on the spot

## How BRIX handles invoicing and payments

1. **Job done, invoice ready.** When the crew marks the job finished, BRIX turns it into an invoice with the work and price that were on the job, so nobody retypes it from a clipboard.
2. **Send it the same day.** The invoice goes to the customer while the work is fresh and the customer is still happy, not a week later when they've forgotten the tech's name.
3. **Chase it politely, automatically.** If the invoice isn't paid, BRIX sends friendly reminders on a schedule you approve, and keeps going until the money is in your account. You decide the tone and when a human should step in.
4. **Sync it to the books.** The invoice and the payment sync to QuickBooks along with the customer, so your accounts receivable in QuickBooks matches what BRIX shows.

**Sample reminder sequence (illustrative wording)**



**Day 0:** Thanks for choosing Ridgeline Electric, Sam. Here's your invoice for today's panel upgrade. Reply here with any questions.

**Day 7:** Hi Sam, a friendly reminder that invoice 1042 for $2,430 is due. Thanks again for the work!

**Day 14:** Hi Sam, invoice 1042 is now a week past due. If something on it doesn't look right, just reply and we'll sort it out.

**Day 21:** Hi Sam, we still show $2,430 open on invoice 1042. Can you let us know when to expect payment? The owner will call if we don't hear back.

Notice the reminders never threaten. They make it easy to pay and easy to raise a problem, which is how you get paid and keep the customer. Our guide on [how to collect unpaid invoices](https://www.brix.so/learn/how-to-collect-unpaid-invoices) covers what to do when reminders run out.

## What should a contractor invoice include?

A contractor invoice should include your business name and contact details, the customer and job address, an invoice number and date, the due date, itemized work and materials, any deposit already paid, sales tax where it applies, the balance due and how to pay. Add your license number if your state requires it on invoices. Our [invoice template](https://www.brix.so/templates/invoice-template) has every field laid out.

**Invoice fields that speed up payment**

| Field | Why it helps you get paid |
| --- | --- |
| Clear due date | "Due on receipt" or "Net 15" tells the customer exactly when. "Payable soon" doesn't. |
| Itemized line items | Customers pay what they understand and question what they don't. |
| Job reference | Links the invoice to the visit, the address and the quote, which ends "what's this for?" calls. |
| Deposit and payments applied | Shows the real balance and prevents double-billing disputes. |
| Payment options | More ways to pay means fewer excuses to wait. |
| Late fee terms (if you use them) | Must be agreed up front, usually in the quote or contract, and must follow your state's rules. |

## How do you get paid faster as a contractor?

To get paid faster, invoice the day the job is done, ask for deposits on large jobs, make paying easy, and follow up on a fixed schedule instead of when you remember. Those four habits move most shops' collection times more than any late fee does.

1. **Invoice on completion.** Same day, ideally before the truck leaves.
2. **Take deposits on big work.** For multi-day jobs, bill in stages. See [progress billing](https://www.brix.so/learn/progress-billing) and, on commercial work, [retainage](https://www.brix.so/learn/retainage).
3. **Set terms in the quote.** The customer agrees to the payment schedule before you start, not after.
4. **Remind on a schedule.** Day 7, day 14, day 21, then a phone call. Automate the first three.
5. **Watch your AR weekly.** Know who owes what. The longer an invoice sits, the less likely it gets paid.

## What happens to the invoice in QuickBooks?

When an invoice syncs, it shows up in QuickBooks against the right customer, and when the payment syncs, it closes that invoice. That's what lets your accountant reconcile the bank account without calling you about every deposit. The common mess is the opposite: invoices typed into two systems, payments recorded in one, and a QuickBooks AR report full of invoices you were paid for months ago.

> **One rule that prevents most sync messes**
>
> Pick one system that creates invoices in QuickBooks. If BRIX sends invoices to QuickBooks, don't also create the same invoice by hand in QuickBooks or from a second app. Two writers equals duplicate invoices. More in the [QuickBooks integration](https://www.brix.so/integrations/quickbooks) guide.

## Call to cash: where invoicing fits

Invoicing is the end of a chain that starts with a ringing phone. The [AI receptionist](https://www.brix.so/features/ai-receptionist) books the visit, you [quote on site](https://www.brix.so/features/quotes-estimates), [sales automation](https://www.brix.so/features/sales-automation) chases the open estimate, the crew does the job, and BRIX invoices it and chases the payment. Then the customer, invoice and payment land in QuickBooks, and [bookkeeping help](https://www.brix.so/features/bookkeeping-taxes) keeps expenses categorized around it. One system, no retyping.

## Frequently asked questions

### What is the best invoicing app for contractors?

Look for one that creates invoices from the job instead of from scratch, sends reminders automatically, records payments and syncs cleanly with QuickBooks. If the app makes pretty invoices but leaves chasing to you, the slowest part of getting paid is still on your plate.

### Can I set up automatic invoice reminders?

Yes. BRIX sends polite reminders on unpaid invoices on a schedule you approve during setup and keeps going until the invoice is paid. You choose the wording and when a person should take over with a phone call.

### When should a contractor send an invoice?

The day the job is finished, ideally before leaving the site. For multi-day projects, send invoices at agreed milestones or bill a deposit up front. Waiting to batch invoices at the end of the week adds days to every payment.

### What are normal payment terms for contractors?

Residential service work is usually due on completion or on receipt. Commercial work often runs Net 30, sometimes with retainage held until the project closes. Put your terms on the quote so the customer agrees before you start.

### Can I charge late fees on unpaid invoices?

Often yes, if the customer agreed to the fee in writing before the work and the fee follows your state's rules. Many owners find a steady reminder schedule collects more than late fees, without souring the relationship. Check your state's rules or ask an attorney before adding fees.

### Do invoices and payments sync to QuickBooks?

Yes. BRIX syncs customers, invoices and payments with QuickBooks, so QuickBooks shows the same open and paid invoices that BRIX does. Avoid creating the same invoice in QuickBooks by hand, or you'll end up with duplicates.

### How do I collect an invoice that's 60 days overdue?

Call the customer, confirm they received the invoice and ask if anything is wrong with it. Offer a payment plan if money is tight. If that fails, a final written demand, small claims court or, for construction work, a [mechanics lien](https://www.brix.so/learn/mechanics-lien) may apply, each with deadlines that vary by state.
