Square Invoices exists because every service business with a phone and a Square account needs to send invoices sometimes. It's good at that. For a contractor whose work is a $600 repair plus travel, it's plenty.
Estimation Builder exists because contractors writing 10+ line items across mixed charge types (square feet, cubic feet, per hour, flat rate) need more than "enter a description and a price." It's not trying to be a payment processor. It's trying to be the best way to get a real construction bid out the door from your phone.
If you're choosing between them, the question is: how complex are your bids?
Square Invoices in one paragraph
Square Invoices is a free-to-paid invoicing tool from Square (the payments company). The free tier sends basic estimates and invoices with Square Payments built in (standard 2.9% + $0.30 credit card fees). The Plus tier ($20/month) adds saved items, milestone payments, custom fields, and a few polish features. It's aimed at service businesses — cleaners, tutors, small service shops, and basic trades.
Estimation Builder in one paragraph

Six charge types matching how contractors actually bid (square feet, cubic feet, quantity, flat rate, per foot, per hour), first-class change orders, branded PDF estimates, one-tap invoice conversion, QuickBooks Online CSV + Desktop IIF monthly export. $75/month flat.

When Square Invoices is the right call
- You're a handyman, cleaner, tutor, or simple service business. Your bills are mostly "hourly rate × hours" or "flat fee for service."
- Your jobs are one line item or a short list.
- You want credit card payments built in at Square's standard rate.
- Budget matters — free is free, and $20/month for Plus is cheap.
- You don't need change orders, multi-unit pricing, or QuickBooks export.
For these use cases, Square Invoices is genuinely great. We wouldn't pretend to fit better.
When Estimation Builder is the right call
- You're writing construction estimates with 5-20+ line items.
- Pricing happens by different units: some work per square foot, some per cubic foot, some flat rate, some per hour.
- Jobs run long enough that change orders happen.
- You use or want to use QuickBooks for accounting.
- You care that the estimate PDF looks like it came from a real construction business — logo, signature, itemized sections — not a generic invoice.
The fundamental difference
Square Invoices is built for service work: you did a job, here's the bill, pay me.
Estimation Builder is built for project work: here's a detailed estimate of what it'll cost, you accept, we do the work (maybe with change orders), here's the invoice.
A handyman fixing a leak is service work. A concrete contractor pouring a driveway is project work. Use the tool that matches.
What Square has that we don't
- Built-in credit card payments. We don't process payments. Your customers pay you via invoice, ACH, check, or a separate payment tool.
- A free tier. We don't have one. 30-day free trial, no credit card, but after that $75/month.
- Payroll and POS integrations via the rest of the Square ecosystem.
What we have that Square doesn't
- Six charge types built for construction math
- First-class change orders tracked against the original estimate
- Branded contractor PDFs (logo + signature + itemized sections)
- QuickBooks Desktop IIF export
- Reusable item catalog purpose-built for construction line items
The honest verdict
- Service business, simple billing, wants payment processing built in: Square Invoices.
- Construction contractor, multi-line-item bids, wants change orders and QuickBooks: Estimation Builder.
If you're a contractor using Square Invoices because it's free, and you find yourself wishing it had proper charge types or real change orders — try Estimation Builder's 30-day free trial. If not, Square is fine.
Frequently Asked Questions
Can I use Square Invoices for construction estimates?
You can use it for simple bids, but it lacks construction-specific features: six charge types (square feet, cubic feet, per foot, per hour, etc.), change orders tracked against original estimates, and QuickBooks export. For real construction estimating, a purpose-built tool like Estimation Builder is a better fit.
Is Square Invoices cheaper than Estimation Builder?
Yes. Square Invoices has a free tier (with payment processing fees) and a $20/month Plus tier. Estimation Builder is $75/month flat. The price difference covers construction-specific features Square doesn't have.
Does Estimation Builder process credit cards like Square does?
No. Estimation Builder focuses on estimating, change orders, invoicing, and QuickBooks export. Payment processing isn't built in — your customers pay you separately via ACH, check, or a payment processor of your choice.
Can Square Invoices export to QuickBooks?
Not natively. You can connect via third-party integrations or manually export CSVs, but it's not a first-class feature. Estimation Builder has built-in monthly QuickBooks export in both Online CSV and Desktop IIF formats.
