TLDR (Summary)
The best invoicing software for freelancers is Plutio ($19/month).
Standalone invoicing tools like FreshBooks ($17-55/month) and Wave (free) create professional invoices but do not connect to where your work actually happens. You track time in Toggl, manage projects in Asana, and create invoices separately... which means line items get estimated from memory and billable work gets missed. Plutio connects invoicing to time tracking, project milestones, and client records, so invoices draft from actual work with a single click.
According to industry research, 85% of freelancers experience late invoice payments. Connected invoicing with automatic reminders and payment links reduces days-to-payment and eliminates the awkward follow-up emails.

What is invoicing software for freelancers?
Invoicing software for freelancers creates, sends, and tracks payment for professional invoices while connecting billing to the actual work delivered.
The distinction matters: basic invoice generators create PDF documents with your logo and payment terms. Accounting software handles the financial records after money moves. Freelancer invoicing software bridges the gap between completing work and collecting payment... tracking which projects have been billed, which invoices are outstanding, which clients pay on time, and automating the reminders that get money into your account faster.
What freelancer invoicing actually does
Core functions include creating branded invoices with your logo and business details, adding line items for services or products, setting payment terms and due dates, sending invoices directly to clients, accepting payments through credit card or bank transfer, tracking invoice status from sent through paid, and sending automatic reminders when payments are overdue. Advanced platforms connect invoicing to time tracking so invoices draft from logged hours.
Invoice generators vs connected invoicing
Free invoice generators create documents but stop there. You download a PDF, email it manually, and track payment in a spreadsheet. Connected invoicing handles the complete payment lifecycle: create the invoice, send it through client portal, track when clients open it, remind them before due dates, accept payment online, and mark it paid automatically when money arrives. The difference shows in payment speed and reduced admin time.
What makes freelancer invoicing different
Freelance billing patterns differ from traditional business invoicing: work happens before payment rather than product delivery at payment, hours vary by project requiring accurate time-to-invoice conversion, milestone billing splits payments across project phases, retainer arrangements need recurring invoices, and client relationships span multiple projects requiring organized billing history. Without invoicing that connects to project delivery, every invoice requires manual calculation and memory-based line item creation.
When invoicing connects to time tracking and project management, invoices create themselves from actual work. No more end-of-month scramble to reconstruct what you did and how long it took.
Why freelancers need invoicing software
Freelancers who handle billing manually face two problems that compound with growth: invoices take longer to create, and payments take longer to collect.
When you have two or three clients, creating invoices from memory works. You remember the projects, estimate the hours reasonably accurately, and send invoices within a few days of completing work. When you have ten or fifteen active clients with overlapping projects, memory fails. Some hours get forgotten. Some work gets billed late. Some invoices get delayed because creating them feels like work itself.
The late payment problem
Research shows 85% of freelancers experience late invoice payments at least some of the time. Late payments create cash flow stress, and the mental overhead of tracking who owes what compounds across multiple clients. Manual follow-up emails feel awkward, so they get postponed, and payment delays stretch further.
The underbilling problem
Disconnected time tracking and invoicing means work falls through the cracks. The extra meeting that ran 45 minutes. The revision round that took three hours. The email thread that consumed an afternoon. When invoices require manual hour calculation, some billable time never gets billed. Across a year of projects, that underbilling adds up to thousands in lost revenue.
The fragmentation problem
Freelancers stack separate tools for time tracking, project management, and invoicing. Toggl logs hours but does not create invoices. FreshBooks creates invoices but does not track projects. The data lives in different places, and you become the integration layer that manually moves information between systems. According to TeamStage research, 36% of freelance time goes to admin tasks that connected tools could automate.
The professionalism problem
Invoices reflect your business. Inconsistent formatting, missing details, or manual payment instructions ("please wire to this account") signal amateur operation. Clients who receive professional invoices with clear payment links and automatic reminders take payment more seriously than those who receive haphazard emails asking for money.
Connected invoicing solves both creation and collection. Invoices draft from tracked time in seconds. Payment links and automatic reminders handle collection. You focus on client work while Plutio handles getting paid for it.
Invoicing features freelancers need
The essential invoicing features for freelancers connect billing to time tracking and project delivery while automating the reminders that speed up payment collection.
Core invoicing features
- Branded templates: Your logo, business details, and payment terms on every invoice. Professional presentation without design work.
- Line item flexibility: Add services, products, hourly rates, flat fees, or custom descriptions. Build invoices that reflect how you actually bill.
- Payment terms: Set due dates, late fees, and payment schedules. Net 15, Net 30, or custom terms per client or project.
- Online payments: Accept credit card and bank transfer directly from invoices through Stripe, PayPal, or Square integration.
- Status tracking: See which invoices are sent, viewed, overdue, and paid at a glance. Know exactly where every dollar stands.
- Automatic reminders: Configure reminder schedules for overdue invoices. Clients get nudged without you sending awkward follow-up emails.
Freelancer-specific features
- Time-to-invoice conversion: Generate invoices directly from tracked time entries. Hours logged against a project become line items automatically. Industry research shows 36% of admin time could be automated.
- Project-based billing: Create invoices linked to specific projects. See which projects have been billed, which are pending, and which are complete.
- Milestone billing: Split payments across project phases. 50% upfront, 25% at draft, 25% on delivery. Invoices trigger at each stage.
- Recurring invoices: Retainer clients get billed automatically on schedule. Monthly, quarterly, or custom intervals without manual creation.
Platform features that multiply value
- Client portals: Clients view and pay invoices through branded portals. Professional self-service that reduces payment friction.
- Payment history: Complete billing record per client showing all invoices, payments, and outstanding balances.
- Multi-currency: Bill international clients in their currency. Invoice in USD, EUR, GBP, or other currencies.
- Accounting integration: Connect to QuickBooks or Xero for financial reporting and tax preparation.
The deciding factor is connection depth. Invoicing that pulls from tracked time eliminates manual calculation. Payment links that work through client portals reduce friction. Automatic reminders handle collection without awkward emails.
Invoicing software pricing for freelancers
Invoicing software for freelancers ranges from free basic tools to $55/month for full-featured platforms, with integrated solutions providing better value than stacking separate subscriptions.
What freelancers typically pay for invoicing tools
- Wave: Free invoicing (limited customization, no time tracking, payment fees on card transactions)
- FreshBooks: $17-55/month (invoicing-focused, time tracking on higher tiers, no project management)
- QuickBooks Self-Employed: $15-25/month (accounting focus, basic invoicing, limited project features)
- PayPal Business: Free invoicing (basic features, 2.9% + $0.30 transaction fees)
These tools handle invoicing but require separate subscriptions for time tracking ($10-20/month) and project management ($10-30/month). Total cost across 3-4 disconnected tools: $40-100/month plus manual data transfer between systems.
Plutio pricing (February 2026)
- Core: $19/month: Unlimited invoicing plus time tracking, proposals, contracts, project management, and client portals.
- Pro: $49/month: Unlimited clients, 30 contributors, advanced permissions, priority support.
- Max: $199/month: Unlimited team, white-label with custom domain, single sign-on.
The ROI calculation for freelancers
- Tool consolidation: Replace FreshBooks ($17-33/month), Toggl ($10/month), and project management ($10-15/month) with one $19/month platform. Saves $18-39/month in subscriptions.
- Faster payments: Automatic reminders and one-click payment links reduce average payment time. Getting paid 10 days faster on a $3,000 invoice improves cash flow significantly.
- Recovered revenue: Connected time-to-invoice eliminates underbilling. Capturing just 2-3 extra hours per month at your rate covers the entire subscription cost.
Invoicing software ROI comes through subscription savings, faster collections, and recovered revenue from billable time that disconnected tools miss. Plutio pays for itself by capturing hours that would otherwise go unbilled.
Why Plutio is the best invoicing software for freelancers
Plutio handles invoicing as part of a complete platform where time tracking, projects, proposals, and client communication work together rather than as separate tools that need manual connection.
Invoices that create themselves
Track time against tasks and projects throughout the month. When billing time arrives, open the project and click to generate an invoice. Plutio pulls tracked hours into line items automatically, with descriptions, rates, and totals calculated. Review, adjust if needed, and send. What used to take 30 minutes of spreadsheet work takes 30 seconds.
Time tracking that feeds billing
Start a timer when you begin work. Stop it when you finish. The time logs against the specific client and project with notes about what you did. Mark entries as billable or non-billable. At invoice time, billable hours are ready to convert. No reconstruction from calendar entries or memory required.
Project-connected invoicing
Every invoice links to the project it covers. See invoice status from project views. See project details from invoice records. When a client asks about a charge, you open the invoice and see exactly which project, which hours, and which deliverables it covers. Complete audit trail without spreadsheet archaeology.
Milestone and recurring billing
Set up milestone billing for larger projects: deposit invoice on signing, progress invoice at drafts, final invoice on delivery. Each milestone triggers the corresponding invoice automatically when marked complete. For retainer clients, recurring invoices send on schedule without manual creation. Monthly retainer on the 1st, automatically, forever.
Payment links that work
Connect Stripe, PayPal, or Square. Invoices include a "Pay Now" button that accepts credit card or bank transfer. Clients click, enter payment details, and money moves. You get notified when payment arrives, and the invoice marks as paid automatically. No more "did they send the check?" uncertainty.
Automatic reminders that handle collection
Configure reminder schedules: friendly nudge 3 days after due date, firmer reminder at 7 days, escalation at 14 days. Clients receive the reminders, you do not send awkward follow-up emails. Reminders handle collection while you focus on current work.
Client portals for self-service payment
Clients log into branded portals and see all their invoices: outstanding, paid, and downloadable for records. Payment happens through the portal with saved payment methods for repeat transactions. Professional experience that reduces payment friction.
Complete billing history
Open any client and see every invoice ever sent: amounts, dates, status, payment dates. Know which clients pay fast and which consistently run late. Information that informs how you handle deposits and payment terms going forward.
Multi-currency support
Work with clients in different countries? Invoice in their currency. Set project currency different from your default. Handle international billing without currency conversion headaches.
Accounting integration
Connect QuickBooks or Xero. Invoice data flows to your accounting software automatically. Tax time becomes simpler with organized financial records that match your invoice history.
Time tracking feeds invoicing, invoicing links to projects, and projects connect to clients, so one system instead of five, with data flowing automatically instead of manually.
How to set up invoicing in Plutio
Setting up invoicing in Plutio takes 1-2 hours for initial configuration, with invoices generating in under a minute once templates and integrations are ready.
Step 1: Configure business details (20 mins)
Add your business name, address, tax ID if applicable, and contact information. These details appear on every invoice automatically. Upload your logo for branded invoicing. Set default payment terms (Net 15, Net 30, or custom).
Step 2: Connect payment processing (15 mins)
Link your Stripe, PayPal, or Square account. Test the connection with a small transaction to yourself. Verify funds deposit correctly before relying on client payments. Configure which payment methods to offer clients.
Step 3: Create invoice templates (30 mins)
Build templates for common billing scenarios:
- Hourly project: Line items that pull from time entries with hourly rate calculations.
- Fixed project: Predefined deliverable line items with flat fees.
- Retainer: Monthly recurring invoice with set amount and service description.
- Milestone: Deposit, progress, and final payment templates for phased projects.
Step 4: Set up automatic reminders (10 mins)
Configure reminder schedule for overdue invoices. Recommended: friendly reminder at 3 days overdue, firmer notice at 7 days, escalation at 14 days. Customize reminder message text to match your communication style.
Step 5: Test complete workflow
Track time on a test project. Generate invoice from tracked time. Send to yourself. Pay through the payment link. Verify the complete cycle works before using with real clients.
Common setup mistakes to avoid
- Skipping payment integration testing: Verify payment processing works before sending your first real invoice. A broken payment link loses money.
- Generic templates: Create specific templates for your common project types rather than one generic template that requires heavy customization each time.
- Forgetting automatic reminders: Configure reminders during setup. Plutio should handle collection from day one.
Most invoicing setup happens once. After templates and integrations are configured, creating and sending invoices takes seconds instead of minutes.
Invoice organization for freelancers
Organizing invoicing creates clarity about cash flow and enables efficient billing across all your client relationships.
Invoice status tracking
- Draft: Invoice created but not yet sent. Review and finalize before sending.
- Sent: Invoice delivered to client. Waiting for payment.
- Viewed: Client opened the invoice. They know payment is due.
- Overdue: Past due date. Automatic reminders active.
- Paid: Payment received. Invoice closed.
Client billing organization
- By client: See all invoices for each client in one view. Understand lifetime billing, payment patterns, and outstanding balances.
- By project: See which projects have been invoiced, which are pending, which have partial payment remaining.
- By status: Filter to see all overdue invoices across clients. Understand total outstanding revenue at a glance.
Information to track
- Invoice amounts and line item breakdowns
- Payment terms and due dates per client
- Payment method preferences (some clients prefer bank transfer, others use cards)
- Average days to payment per client (reveals which clients need deposits)
- Year-to-date billing for tax preparation and business planning
Proven methods
- Invoice promptly after completing work or milestones. Delayed invoicing delays payment.
- Use consistent numbering for easy reference and professional appearance
- Include project references on invoices so clients know what they're paying for
- Save payment receipts automatically for tax records
Organized invoicing enables cash flow visibility. It's easy to see exactly how much is outstanding, how much is overdue, and which clients need follow-up. Structure enables action instead of uncertainty.
Client portals for freelancers: invoicing connection
Client portals connect invoicing to client-facing self-service, creating professional payment experiences that reduce friction and speed up collection.
Portal as payment hub
Clients log into branded portals and see all their invoices in one place. Outstanding invoices show "Pay Now" buttons. Paid invoices stay accessible for records and accounting. Payment happens within the portal experience, not through redirects to unfamiliar payment pages.
Professional payment experience
Portal payments reflect your brand, not a payment processor's generic checkout. Clients see your logo, your colors, and your business name throughout the payment flow. Professional presentation reinforces the value of your work.
Self-service access
Clients download invoices and receipts without emailing you. When their accounting department needs documentation, they access the portal and pull what they need. Reduced admin back-and-forth for both sides.
Saved payment methods
Clients can save payment methods for faster checkout on future invoices. Returning clients pay with a click instead of re-entering card details. Lower friction means faster payment.
Invoice history visibility
Clients see their complete billing history: every invoice, every payment, every receipt. Transparency builds trust and reduces "I thought we already paid for that" confusion.
Portals make invoicing client-friendly. Professional presentation, easy payment, and self-service access combine to reduce payment friction and improve collection speed.
How to migrate invoicing to Plutio
Migration from another invoicing platform typically takes 2-3 hours of active work, with the best time to switch being at the start of a new billing cycle.
Step 1: Export from your current tool
Export your client list and invoice history from your current invoicing software:
- FreshBooks: Settings > Export Data. Download clients and invoice history as CSV.
- Wave: Settings > Data Export. Request full data export including invoices.
- QuickBooks: Reports > Customers > Export. Includes billing history.
Step 2: Set up payment processing in Plutio (20 mins)
Connect your payment processor (Stripe, PayPal, or Square). You can use the same accounts you had with your previous invoicing tool. Payment continuity maintained.
Step 3: Import client data (30 mins)
Import your client list to Plutio via CSV. Map fields appropriately. Historical invoice data can be referenced from exports but does not need to be imported... focus on forward-looking billing.
Step 4: Create invoice templates (1 hour)
Build templates for your common billing scenarios. Reference past invoices from your old tool to make sure consistency in formatting and line item descriptions.
Step 5: Run parallel for transition period
Complete any outstanding invoices in your old system. Start all new invoices in Plutio. Clients receiving their first Plutio invoice see similar branding and terms, minimizing confusion.
Step 6: Phase out old tool
Once all outstanding invoices from the old system are paid (typically 30-60 days), cancel that subscription. Keep exports for records.
Common migration pitfalls to avoid
- Switching mid-invoice cycle: Finish outstanding invoices in the old system. Do not create partial invoices in both places.
- Forgetting to update payment details: make sure your bank account or payment processor connections are active in Plutio before sending invoices.
- Not testing first: Send a test invoice to yourself and pay it before invoicing real clients.
Migration investment pays back immediately. Connected invoicing that pulls from tracked time saves hours monthly compared to manual invoice creation.
