Estimates and invoices should feel like two stages of the same job.

The estimate explains what the business plans to do and how much it expects the work to cost. The invoice requests payment after the work is completed or a billing milestone is reached.

Yet many small businesses create these documents in completely separate systems.

The owner prepares an estimate in a spreadsheet, saves it as a PDF, emails it to the customer, adds the accepted job to a calendar, and later rebuilds the same line items in an invoicing app.

That disconnected process creates unnecessary work and increases the risk of:

• Charging a different amount from the approved estimate
• Forgetting deposits or previous payments
• Missing approved additional work
• Entering customer information twice
• Delaying the final invoice
• Losing track of unpaid balances
• Using inconsistent service prices

I tested popular software that combines estimating and invoicing in one tool. I used realistic workflows for US contractors, home service companies, consultants, repair businesses, landscapers, cleaners, and other small service providers.

The test covered mobile estimates, customer approvals, deposits, optional services, progress invoices, change orders, online payments, payment reminders, accounting, and estimate-to-invoice conversion.

After comparing the options, Joist was my best overall estimating and invoicing software for solo contractors and very small service businesses.

Jobber was the stronger option when estimates and invoices needed to connect with scheduling and field operations. QuickBooks Online was better for businesses that wanted complete accounting, while Housecall Pro made more sense for growing home service teams with several technicians.

Best Estimating and Invoicing Software at a Glance

Software	Best for	Starting price	Main strength
Joist	Best overall for contractors	$10 per month	Fast estimate-to-invoice workflow
Jobber	Service businesses	From $29 per month annually	Quotes connected to scheduling and jobs
QuickBooks Online	Accounting-focused businesses	Varies by plan	Estimates connected to bookkeeping
Housecall Pro	Growing home service teams	From $59 per month	Field estimates and progress invoicing
FreshBooks	Freelancers and hourly services	Tiered paid plans	Simple time tracking and billing
Zoho Invoice	Businesses wanting free billing tools	Free core product	Affordable estimates and invoices
Wave	New solo businesses	Free and paid options	Basic invoicing and financial organization

Pricing, promotions, included users, document limits, and payment-processing fees can change. Always compare the plan your business would actually use rather than relying only on the advertised starting price.

How I Tested the Software

I ran six realistic jobs through each platform.

A Basic Repair

The first estimate included:

• Service-call fee
• Two hours of labor
• Replacement parts
• Small materials
• Sales tax where applicable
• Estimate expiration date

After customer approval, I converted the estimate into an invoice and recorded payment.

A Job Requiring a Deposit

The second project had a total estimated price of $8,000.

The business required:

• $2,400 deposit
• $2,800 midway through the project
• $2,800 at completion

This tested deposits, milestone invoices, previous-payment tracking, and remaining balances.

A Quote With Optional Services

The third customer received:

• A basic repair
• An upgraded repair option
• A full replacement option
• An optional maintenance service

This tested whether the customer could select additional items without approving unwanted work.

A Change in Scope

The customer requested additional work after approving the original estimate.

I checked whether the software could document the new work and update the final amount without hiding the original agreement.

A Mobile Estimate

The fifth estimate was created from a phone at the customer’s property.

This tested:

• Mobile speed
• Saved products and services
• Markups
• Taxes
• Photos
• Customer approval
• Digital signatures

An Overdue Invoice

The final invoice remained unpaid.

This tested:

• Payment reminders
• Invoice status
• Online payment links
• Customer balances
• Accounts receivable visibility

1. Joist: Best Estimating and Invoicing Software Overall

Joist produced the smoothest estimate-to-invoice workflow for contractors and small service businesses.

The platform is designed around estimates, invoices, approvals, payments, and contractor documentation. Users can create an estimate and convert it into an invoice without entering the same customer and line-item information again.

Joist currently offers:

• Basics: $10 per month
• Pro: $17 per month
• Elite: $32 per month

The Basics plan is limited to five estimates or invoices per month. It includes digital signatures, online payments, deposits, milestone payments, Tap to Pay, and mobile and web access. Joist also offers a 14-day trial without requiring a credit card.

Estimate Creation

Joist made it easy to build an itemized estimate containing:

• Labor
• Materials
• Quantities
• Unit prices
• Taxes
• Discounts
• Markups
• Notes
• Terms
• Photos

A contractor could create the estimate at the job site instead of writing notes and rebuilding the document later.

That is useful for painters, electricians, plumbers, handypersons, remodelers, flooring installers, roofers, and similar contractors who regularly prepare estimates in the field.

Customer Approval

The customer could review and approve the estimate electronically.

This creates a clearer record than a casual text message saying, “That price is fine.”

Approval records are especially important when the scope, price, deposit, or project terms may later be questioned.

Estimate-to-Invoice Conversion

This was Joist’s strongest feature.

Once the customer approved the estimate and the work was completed, I could turn it into an invoice without reentering:

• Customer details
• Service address
• Labor
• Materials
• Taxes
• Discounts
• Project description

The conversion reduced duplicate work and made it less likely that the invoice would accidentally differ from the approved estimate.

Deposits and Milestone Payments

Joist worked well for the $8,000 project.

The customer could pay the initial deposit, while later milestone payments remained connected to the project.

A clear payment schedule might look like this:

Payment stage	Amount
Deposit at approval	$2,400
Mid-project payment	$2,800
Final payment	$2,800
Total	$8,000

The invoice history should clearly show what the customer has already paid and what remains due.

What I liked

Joist was strongest for:

• Fast mobile estimates
• One-click estimate-to-invoice conversion
• Digital signatures
• Deposits
• Milestone payments
• Online payments
• Customer profiles
• Contractor-friendly documents
• Low monthly pricing
• Simple setup

Where Joist falls short

Joist is primarily an estimating and invoicing application.

It does not provide the same dispatching, recurring scheduling, technician tracking, route management, or advanced customer communication found in complete field service platforms.

It is also not a replacement for full accounting software. A business may still need QuickBooks or another bookkeeping system for:

• Bank reconciliation
• Expense categorization
• Vendor bills
• Financial statements
• Tax preparation
• Payroll

The five-document limit on the Basics plan is also restrictive for an active contractor.

Best for

Choose Joist when you are a solo contractor or very small business that mainly needs professional estimates, invoices, approvals, deposits, and payments.

My verdict: Best overall estimating and invoicing tool for contractors.

2. Jobber: Best for Service Businesses

Jobber was the strongest option when the accepted estimate needed to become a scheduled service job.

Its quotes are fully connected to the broader workflow. An approved quote can become a job, be added to the schedule, completed by a technician, and converted into an invoice.

Complete Workflow Test

Jobber handled the entire process:

• Customer requests service.
• Business creates a quote.
• Customer approves the quote.
• Office schedules the job.
• Technician completes the work.
• Business creates the invoice.
• Customer pays online.

That is more useful than estimate-and-invoice software alone when the company also needs to manage appointments and field employees.

Saved Products and Services

Jobber allows businesses to create a default list of products and services with saved names, descriptions, quantities, and unit prices.

Those items can then be added to quotes, jobs, and invoices. Selected plans also support product images and markups.

This helps businesses quote consistently.

For example, a plumbing company could save standard items for:

• Service-call fee
• Drain cleaning
• Toilet installation
• Water-heater inspection
• Faucet replacement

Technicians would not need to type each description and price from the beginning.

Optional Services and Upsells

Jobber can support optional items on quotes, depending on the plan.

A landscaping company might include:

• Required weekly mowing
• Optional hedge trimming
• Optional fertilizer treatment
• Optional seasonal cleanup

The customer can select the extras they want rather than approving an entirely separate estimate.

Deposits and Progress Invoicing

Jobber supports progress invoicing, allowing a business to divide one job into multiple invoices.

A payment schedule can include a deposit followed by fixed-dollar or milestone payments as work progresses.

This makes Jobber more useful for larger repairs, installations, and multi-day service projects.

Automatic Payments

Customers can save payment methods to their Jobber Wallet for future invoices or automatic payments. Payment information can also be saved when a customer pays a required quote deposit.

This can reduce payment delays for recurring services.

What I liked

Jobber was strongest for:

• Quotes connected to scheduling
• Estimate-to-job conversion
• Technician assignments
• Saved price lists
• Markups and margin visibility
• Optional quote items
• Deposits
• Progress invoicing
• Customer portal
• Online and automatic payments

Where Jobber falls short

Jobber costs considerably more than Joist when the business only needs estimates and invoices.

Some useful quoting, markup, job-costing, automation, and progress-billing features may require a higher plan.

Jobber also remains operational software rather than complete accounting software. Many businesses connect it to an accounting platform instead of using it as the only financial system.

Best for

Choose Jobber when your business needs estimates and invoices connected to customer requests, scheduling, technicians, recurring work, and payments.

My verdict: Best for small field service businesses.

3. QuickBooks Online: Best for Accounting

QuickBooks Online made the most sense when estimating and invoicing needed to connect directly to bookkeeping.

QuickBooks allows users to create an estimate and later convert it into an invoice, avoiding the need to enter the customer and service information twice.

Accounting Workflow

QuickBooks can connect customer billing with:

• Bank transactions
• Business expenses
• Vendor bills
• Accounts receivable
• Sales tax
• Financial statements
• Cash-flow reports
• Tax records

This gives QuickBooks a major advantage over dedicated estimate-and-invoice apps.

Joist may create the document more quickly. QuickBooks provides a more complete view of what the transaction means for the business’s finances.

Estimate-to-Invoice Test

The process was straightforward for a basic job.

I created an estimate, received customer approval, and converted the accepted amount into an invoice.

That conversion helps maintain consistency between what was proposed and what was charged.

Progress Billing

QuickBooks can work for businesses that bill an accepted estimate in stages, although the exact functions depend on the plan and account configuration.

It is suitable for straightforward deposits and progress invoices. Contractors requiring detailed retainage, construction payment applications, or sophisticated change-order management may need construction-specific software.

Invoice Follow-Up

QuickBooks offers automated invoicing and payment-reminder features. Its US invoicing product currently promotes AI-assisted reminders intended to help businesses collect payments faster.

What I liked

QuickBooks Online was strongest for:

• Estimates
• Estimate-to-invoice conversion
• Customer balances
• Online payments
• Automated reminders
• Bank connections
• Expenses
• Vendor bills
• Financial statements
• Tax preparation

Where QuickBooks falls short

QuickBooks is accounting software first.

It is not the easiest option for a contractor who wants to create a quick estimate from a phone at the customer’s property.

It also lacks the complete field service workflow available in Jobber and Housecall Pro.

Businesses may still need separate software for:

• Scheduling
• Dispatching
• Technician statuses
• Job photos
• Property histories
• Route planning

Best for

Choose QuickBooks Online when estimates and invoices must become part of the company’s complete accounting record.

My verdict: Best accounting-first option.

4. Housecall Pro: Best for Growing Home Service Teams

Housecall Pro combines estimates and invoices with scheduling, dispatching, customer communication, pricebooks, field documentation, and payments.

It is particularly useful for HVAC, plumbing, electrical, appliance-repair, garage-door, and other residential service companies.

Field Estimate Test

Technicians can create estimates from the field and send them to customers for review.

The platform also allows businesses to customize individual estimates and customer-facing invoice information.

A technician can present the estimate, receive approval, perform the work, and move the customer into invoicing without returning to the office.

Pricebook Test

Housecall Pro can use an established pricebook so technicians select approved services and materials rather than building every estimate manually.

That can reduce inconsistent pricing between employees.

Progress Invoicing

Housecall Pro supports progress invoicing for larger or multi-day jobs.

Businesses can bill customers by a fixed dollar amount or a percentage of the total job price, with milestones and due dates connected to the payment schedule.

For example, a $12,000 installation could be billed as:

• 30% deposit: $3,600
• 40% at installation: $4,800
• 30% after completion: $3,600

Customer Communication

Housecall Pro can connect estimates and invoices with:

• Appointment confirmations
• Reminder messages
• Technician arrival updates
• Estimate emails or texts
• Invoice links
• Payment requests
• Review requests

This makes it more complete than a standalone estimating application.

What I liked

Housecall Pro was strongest for:

• Technician-created estimates
• Standardized pricebooks
• Scheduling and dispatching
• Progress invoices
• Customer notifications
• Mobile payments
• Multi-technician workflows
• Residential service businesses

Where Housecall Pro falls short

The platform may be excessive for a solo contractor who does not need dispatching.

The final cost can also increase as the business adds users, sales proposals, reporting, communication services, financing, and other features.

Best for

Choose Housecall Pro when multiple technicians need to prepare estimates and invoices while the office manages schedules and customer communication.

My verdict: Best for growing home service companies.

5. FreshBooks: Best for Hourly and Professional Services

FreshBooks works well for freelancers, consultants, and small businesses that create estimates based primarily on time.

It can combine:

• Estimates
• Time tracking
• Invoices
• Deposits
• Expenses
• Recurring billing
• Payment reminders
• Online payments

Time-Based Estimate Test

FreshBooks was useful for a project requiring an estimated number of hours.

For example:

Service	Hours	Rate	Total
Initial consultation	2	$125	$250
Project work	20	$125	$2,500
Final review	3	$125	$375
Estimated total			$3,125

The business can later track actual time and create the invoice.

Where FreshBooks fits

FreshBooks is appropriate for:

• Consultants
• Designers
• Photographers
• Marketing professionals
• Inspectors
• Project managers
• Maintenance specialists
• Small agencies

Where FreshBooks falls short

FreshBooks is not built specifically for contractors or field service teams.

It lacks:

• Dispatch boards
• Technician assignments
• Trade pricebooks
• Property histories
• Advanced job costing
• Construction change orders

Best for

Choose FreshBooks when estimates and invoices are based mainly on labor hours or professional-service fees.

My verdict: Best for time-based services.

6. Zoho Invoice: Best Free Option

Zoho Invoice is a practical choice for businesses that want estimates and invoices in one system without paying for a full field service platform.

It can help manage:

• Customer records
• Estimates
• Invoices
• Taxes
• Discounts
• Recurring invoices
• Payment reminders
• Customer portals
• Online payment integrations

What I liked

Zoho Invoice offers enough core functionality for a new business that has outgrown editable templates.

An accepted estimate can move into invoicing without creating an entirely new customer record and document.

Where Zoho Invoice falls short

It is not complete field service or accounting software.

The business may still need separate tools for:

• Scheduling
• Technician dispatching
• Full bookkeeping
• Job costing
• Change orders
• Inventory
• Project management

Best for

Choose Zoho Invoice when budget is the main concern and the business needs straightforward estimates, invoices, and reminders.

My verdict: Best free estimating and invoicing option.

7. Wave: Best for New Solo Businesses

Wave can work for a new solo business with simple estimating and invoicing needs.

It provides basic customer billing and financial organization through free and paid products.

What I liked

Wave can help a business:

• Create customer invoices
• Record payments
• Track unpaid balances
• Organize basic income
• Record simple expenses
• Accept online payments

Where Wave falls short

Wave is not designed around field service or contractor estimating.

It lacks the stronger estimate approval, change-order, scheduling, technician, pricebook, and job-costing workflows offered by the leading platforms.

Best for

Choose Wave when you have a very small number of customers and need basic billing at a low cost.

My verdict: Best basic starting option.

My Final Rankings

Best overall: Joist

Joist offered the fastest and simplest workflow from estimate to approval, invoice, and payment.

Best for service businesses: Jobber

Jobber was stronger when estimates needed to become scheduled jobs managed by employees in the field.

Best for accounting: QuickBooks Online

QuickBooks provided the strongest bookkeeping, expense, tax, and financial-reporting foundation.

Best for growing home service teams: Housecall Pro

Housecall Pro connected technician estimates and invoices with scheduling, dispatching, pricebooks, and customer updates.

Best for time-based services: FreshBooks

FreshBooks worked well for consultants and businesses that bill mainly by the hour.

Best free option: Zoho Invoice

Zoho Invoice provided strong basic estimates and invoices without requiring a full software subscription.

Best for new solo businesses: Wave

Wave offered a simple introduction to customer billing and payment tracking.

Features to Test Before Choosing

Before subscribing, run a real job through the software.

Create an Itemized Estimate

Include:

• Labor
• Materials
• Equipment
• Taxes
• Discounts
• Optional services
• Expiration date
• Payment terms

Add a Markup

Enter an internal material cost and calculate the selling price.

Make sure the customer cannot see your private cost or margin.

Request a Deposit

Create a $10,000 estimate requiring a $3,000 deposit.

The system should clearly show:

Description	Amount
Approved estimate	$10,000
Deposit received	$3,000
Remaining balance	$7,000

Add Optional Work

Create one required service and two optional upgrades.

Confirm that the customer can approve only the items they want.

Convert the Estimate

Turn the accepted estimate into an invoice.

Check whether the following carry over correctly:

• Customer information
• Service address
• Line items
• Taxes
• Discounts
• Deposit
• Terms
• Final total

Create a Progress Invoice

Divide one project into several payment stages.

Confirm that each invoice shows earlier payments and the remaining job balance.

Send a Reminder

Leave one invoice unpaid and test the automatic follow-up process.

Review the message from the customer’s perspective.

Common Estimating and Invoicing Mistakes

Reentering the Same Information

The main reason to use one tool is to avoid recreating customer, service, and pricing details.

Choose software that converts estimates directly into invoices.

Changing the Price Without Explaining It

The final invoice could be different from the estimate when the customer requests more work or hidden conditions are discovered.

Document every change clearly.

Forgetting Deposits

The final invoice should show all previous payments.

Otherwise, the customer may believe they are being charged twice.

Sending Vague Line Items

Avoid descriptions such as “repair,” “labor,” or “project work.”

Explain exactly what is included.

Starting Work Without Approval

Use a digital approval or signature for significant jobs.

The accepted estimate should establish the approved scope, price, and terms.

Ignoring Payment Fees

Card and ACH processing may cost extra even when the software subscription is inexpensive.

Include processing costs when setting prices.

Confusing Invoicing With Accounting

Estimating and invoicing software tracks what customers owe.

It may not provide complete bookkeeping, bank reconciliation, tax reports, or financial statements.

Conclusion

After testing estimating and invoicing software in one tool, Joist was the best overall option for solo contractors and very small service businesses.

It made it easy to prepare estimates from a phone, capture customer approval, request deposits, convert approved work into invoices, and collect payment without entering everything again.

Jobber was the better choice when estimates needed to become scheduled jobs managed by field employees. QuickBooks Online made more sense when invoicing had to connect with complete accounting and financial reporting. Housecall Pro was stronger for growing home service businesses with several technicians.

FreshBooks worked well for hourly and professional services, while Zoho Invoice provided the strongest free option. Wave remained useful for new solo businesses with basic billing needs.

Before choosing a platform, test the complete workflow.

Create an estimate. Add labor and materials. Apply a markup. Include an optional service. Request a deposit. Collect customer approval. Convert the estimate into an invoice. Record the payment. Then review the remaining balance.

The best estimating and invoicing software is not simply the tool that creates both documents.

It is the platform that keeps the approved price, completed work, previous payments, and final amount connected from the beginning of the job to the end.
