Switching from QuickBooks Invoicing to Corinthian: What to Expect

Switching from QuickBooks Invoicing to Corinthian: What to Expect

QuickBooks is the default invoicing tool for millions of businesses. If you're reading this, you're probably using it right now, and something about it isn't working for you. Maybe it's the pricing. The invoicing features may feel like an afterthought bolted onto accounting software. Maybe you need dunning workflows and QuickBooks's payment reminders are too basic.

Whatever the reason, this guide gives you an honest comparison of QuickBooks invoicing versus Corinthian, walks through the migration process, and tells you upfront where each platform is stronger.

The Fundamental Difference

QuickBooks is accounting software that includes invoicing. Corinthian is invoicing and revenue operations software.

That distinction shapes everything. QuickBooks optimizes for the accounting workflow: record the transaction, categorize the expense, generate the tax report. Invoicing is one feature among many, and it's designed to feed data into the accounting engine.

Corinthian optimizes for the revenue collection workflow: create the invoice, deliver it reliably, track whether it was received and opened, follow up when it's overdue, collaborate as a team on exceptions, and collect the payment. Revenue operations is the entire product.

Neither approach is wrong. They serve different priorities. If your primary need is accounting with basic invoicing, QuickBooks is built for that. If your primary need is getting invoices paid reliably and managing the collection process at scale, Corinthian is built for that.

Feature-by-Feature Comparison

Here's an honest breakdown of how the two platforms compare on specific features:

Invoice Creation

QuickBooks: Solid invoice builder with customizable templates. Supports multiple line items, tax calculations, and discount codes. Template customization is limited -- you can change colors and add a logo, but the layout options are constrained. Creating an invoice is straightforward but involves navigating through QuickBooks's general-purpose UI.

Corinthian: Purpose-built invoice editor with more layout flexibility. Supports the same line item, tax, and discount features. The UI is designed exclusively for invoicing, so there's less navigational overhead. Template customization is deeper -- you control layout, typography, and branding elements.

Verdict: Comparable on basics. Corinthian offers more customization. QuickBooks has the advantage of being already set up if you're an existing user.

Invoice Delivery

QuickBooks: Sends invoices by email. Provides basic delivery confirmation. Limited visibility into whether the customer actually opened the email. No bounce handling or retry logic.

Corinthian: Full delivery lifecycle tracking: sent, delivered, bounced, opened, clicked. Automatic bounce handling with retry. Alternate delivery channel support. Delivery status feeds into dunning workflows so follow-up adapts to delivery outcomes.

Verdict: Corinthian is significantly stronger here. Delivery tracking alone justifies the switch for businesses that struggle with invoice visibility.

Payment Reminders

QuickBooks: Basic automated reminders. You can schedule reminders before and after the due date. Limited customization of reminder content and timing. One-size-fits-all approach -- the same reminder goes to every customer.

Corinthian: Full dunning workflow engine. Visual workflow builder for defining escalation sequences. Support for branching based on customer segment, invoice amount, delivery status, and payment history. Tone progression across the sequence. Wait states, conditions, and multiple action types (email, SMS, team assignment, late fees).

Verdict: Corinthian's workflow engine is in a different category. If you need anything beyond basic "send a reminder on day 7" functionality, Corinthian is the clear choice.

Team Collaboration

QuickBooks: Multi-user access with role-based permissions. Users can see invoices and customer records. No built-in communication collaboration -- if a customer responds to an invoice email, the reply goes to whoever's email was in the "from" field. No internal notes on invoices, no thread assignments, no shared inbox.

Corinthian: Inbox-based collaboration with thread assignments, internal notes, canned responses, and team-wide visibility. Every customer interaction about an invoice is captured in a shared thread. Handoffs between team members preserve full context.

Verdict: Corinthian wins decisively for teams. QuickBooks works fine for single-user invoicing but breaks down when multiple people need to coordinate on billing.

Payment Processing

QuickBooks: QuickBooks Payments (built-in) with credit card and ACH support. Competitive processing rates. Deep integration with the accounting side -- payments automatically reconcile to invoices and update your books.

Corinthian: Stripe integration for payment processing. Supports whatever payment methods you've enabled in Stripe. Payment data syncs to invoice records automatically. No built-in accounting reconciliation (Corinthian isn't accounting software).

Verdict: QuickBooks has the edge if you want payments to flow directly into your accounting. Corinthian has the edge if you already use Stripe or want more flexibility in payment methods.

Accounting and Reporting

QuickBooks: This is QuickBooks's home turf. Full double-entry accounting, chart of accounts, P&L statements, balance sheets, tax reports, bank reconciliation. Invoicing data feeds directly into financial statements.

Corinthian: Not accounting software. Provides AR-focused reporting: DSO, aging reports, collection rates, delivery metrics, dunning performance. For accounting, you'd export data or integrate with your accounting system.

Verdict: QuickBooks wins on accounting. Corinthian wins on AR operations reporting. If you need both, you can use them together.

Pricing

QuickBooks pricing changes with promotions and may vary by region. As of 2026-03-28, Intuit's U.S. pricing page listed:

QuickBooks Online Simple Start: $38/month before promos. Includes invoicing plus full accounting. Invoice customization is basic at this tier.

QuickBooks Online Essentials: $75/month before promos. Adds multi-user access (3 users) and bill management.

QuickBooks Online Plus: $115/month before promos. Adds inventory tracking, project profitability, and 5 users.

Corinthian: Free tier with core invoicing features. Paid plans for team collaboration, dunning workflows, and API access. Pricing is per-team, not per-feature-unlock.

Verdict: Depends on what you need. If you're paying for QuickBooks primarily for invoicing (not accounting), you're likely overpaying. If you need both invoicing and accounting, QuickBooks's bundled pricing may be more economical than paying for two separate tools.

When to Switch (And When Not To)

Switch to Corinthian if:

• Your main pain is collections. QuickBooks's reminders are too basic, and you need structured dunning workflows with escalation, branching, and tone progression.

• You need delivery tracking. You don't know whether your invoices are being received, and you suspect some overdue invoices are actually delivery failures.

• Multiple people handle invoicing. You need shared inbox, thread assignments, and internal notes. QuickBooks's multi-user access isn't built for collaborative billing workflows.

• You're developer-oriented. You want to automate invoice creation, integrate with other systems via API, and build custom workflows. Corinthian's API-first architecture supports this. QuickBooks has an API, but it's designed for accounting integrations, not invoicing automation.

• You're paying for QuickBooks primarily for invoicing. If you don't use the accounting features, you're paying $30-90/month for an invoicing tool that doesn't excel at collections.

Stay with QuickBooks if:

• You heavily use the accounting features. P&L, balance sheet, tax reports, bank reconciliation, expense categorization. Corinthian doesn't replace any of this.

• You need payroll integration. QuickBooks handles payroll as part of the same platform. Corinthian doesn't.

• Your invoicing is simple and low-volume. If you send 10-20 invoices a month, all get paid on time, and you don't need dunning or team collaboration, QuickBooks's invoicing is perfectly adequate.

• Your accountant expects QuickBooks. Many accountants are trained on QuickBooks and prefer working with its reports. Switching to a different invoicing system means exporting data for your accountant, which adds friction.

Use Both

Many Corinthian users keep QuickBooks for accounting and use Corinthian for invoicing and collections. The workflow looks like:

1. Create and send invoices through Corinthian
2. Track delivery and manage dunning in Corinthian
3. Export payment data to QuickBooks for accounting reconciliation
4. Run financial reports in QuickBooks

This gives you the best of both worlds: Corinthian's strengths in revenue operations, QuickBooks's strengths in accounting.

The Migration Process

Step 1: Export Customer Data from QuickBooks

In QuickBooks, go to Reports > Customers & Receivables > Customer Contact List. Export as CSV.

The export includes:

• Customer name
• Email address
• Billing address
• Phone number
• Outstanding balance
• Terms

Step 2: Import Customers into Corinthian

In Corinthian, go to Settings > Import > Customers. Upload the CSV file.

Corinthian maps the columns automatically. Review the mapping, correct any mismatches, and confirm the import. Customer records are created immediately.

What to watch for:

• Duplicate customers (same company, different contacts) -- decide whether to merge or keep separate
• Inactive customers -- consider whether to import them or start fresh
• Missing email addresses -- you'll need these for invoice delivery

Step 3: Export Open Invoices

In QuickBooks, go to Reports > Customers & Receivables > Open Invoices. Export as CSV.

For each open invoice, you'll get:

• Invoice number
• Customer name
• Amount
• Due date
• Status (open, overdue)

Step 4: Recreate Open Invoices in Corinthian

You have two options:

Manual recreation: For small numbers of open invoices (under 50), create them manually in Corinthian. This gives you the cleanest data.

CSV import: For larger volumes, use Corinthian's invoice import. Upload the CSV, map the fields, and confirm. Imported invoices are created in "draft" status so you can review before sending.

Important: Don't send imported invoices to customers who already received them through QuickBooks. Mark them as "sent" manually or use them only for tracking purposes.

Step 5: Configure Stripe (If Applicable)

If you're switching from QuickBooks Payments to Stripe:

1. Set up your Stripe account if you don't have one
2. Connect Stripe to Corinthian (see our Stripe integration guide)
3. Enable payment links on new invoices

Timing note: Don't disconnect QuickBooks Payments until all outstanding QuickBooks invoices are paid. Customers who received invoices through QuickBooks should be able to pay through the same channel.

Step 6: Set Up Dunning Workflows

This is the feature most people are switching for. Before creating workflows:

1. Review your current follow-up process (even if it's informal)
2. Define your escalation timeline: how many days between each contact?
3. Write or customize your dunning email templates
4. Decide on segmentation: do different customer types get different treatment?

Start with a simple three-step workflow and refine based on results.

Step 7: Run in Parallel

For the first 30 days, run both systems. Create new invoices in Corinthian. Continue monitoring outstanding QuickBooks invoices in QuickBooks. This overlap period lets you verify that Corinthian handles your workflows correctly before fully committing.

After 30 days, once you're confident in the Corinthian setup:

• Stop creating new invoices in QuickBooks
• Continue monitoring QuickBooks for any remaining outstanding invoices
• Once all QuickBooks invoices are resolved, you can reduce your QuickBooks subscription or cancel if you don't need the accounting features

What You'll Gain

Delivery visibility. For the first time, you'll know whether customers actually received your invoices. This alone changes how you think about overdue invoices.

Structured collections. Instead of ad hoc reminders, you'll have automated workflows that escalate predictably and adapt to customer behavior.

Team coordination. Everyone involved in billing can see the same information, communicate in shared threads, and hand off work without losing context.

Faster payments. The combination of reliable delivery, pre-due reminders, and structured dunning often helps teams reduce DSO over time.

What You'll Miss

Integrated accounting. QuickBooks's biggest strength is that invoicing data flows directly into your financial statements. With Corinthian, you'll need to export data or set up an integration for accounting purposes.

All-in-one simplicity. QuickBooks does invoicing, accounting, payroll, and expense tracking in one platform. Switching to Corinthian means managing a separate tool for billing, which adds one more login and one more data source.

Accountant familiarity. If your accountant works in QuickBooks, they'll need to adjust their workflow to accommodate data coming from a different source.

These are real tradeoffs. The right choice depends on whether the gains in revenue operations outweigh the added complexity of running a separate invoicing system.

Making the Decision

Ask yourself three questions:

1. What percentage of your invoices go overdue? If it's under 5%, your current system is working fine. If it's over 15%, you have a collections problem that better tooling can solve.

2. How many people touch your billing process? If it's one person, QuickBooks works. If it's three or more, you need collaboration features.

3. Do you know your invoice delivery rate? If you can't answer this question, you have a visibility gap that's costing you money.

If your answers point to Corinthian, start with the parallel run approach. Keep QuickBooks for accounting, add Corinthian for invoicing and collections, and let the results speak for themselves.

Start your migration to Corinthian -- you can run it alongside QuickBooks from day one.
