InvoiceAgent vs Harvest
Harvest starts with native time, expenses, projects, budgets, and team reporting, then turns that work into invoices. InvoiceAgent starts with the invoice delivery job and imports approved time from WakaTime or Toggl when the team wants to keep its existing tracker.
Choose Harvest
Choose Harvest when the same product should capture team time, monitor projects and budgets, generate invoices, collect supported online payments, and feed accounting.
Choose InvoiceAgent
Teams that already use WakaTime or Toggl and want scheduled PDF delivery, test sends, reminders, processor-independent payment instructions, and send-time FX.
Timing-first invoicing
Schedule the invoice once. Weekend rules, reminders, recurring sends, manual-send overrides, and PDF delivery stay coordinated from one queue.
Live FX at dispatch
Draft early in the source currency. Let the final conversion happen when the invoice actually goes out.
Branding and time-tracking built in
Choose invoice templates, colors, fonts, logo treatment, and import billable hours from WakaTime or Toggl without adding another tool.
What this comparison is for
Freelancers, consultants, agencies, and professional-services teams deciding whether time tracking or invoice delivery should anchor the workflow.
Here is the real tradeoff.
Choose Harvest when time capture, project reporting, invoice generation, online payments, and accounting handoff should stay together. Choose InvoiceAgent when time already lives in WakaTime or Toggl and delivery timing, PDF proof, and send-time FX are the missing layer.
Why teams switch
Your team already tracks work in WakaTime or Toggl and does not need to migrate projects, timers, budgets, and reporting into Harvest.
Why teams switch
You need the latest available exchange rate applied automatically at send time; Harvest supports multiple currencies but documents no currency conversion.
Why teams switch
You want a branded PDF attached to a testable email and one queue for scheduled, sent, failed, and paid invoice states.
Why teams switch
You collect by bank transfer or another chosen provider and do not need Stripe or PayPal to be embedded in the invoicing product.
Side-by-side without the marketing fog.
Core audience
Service businesses that want invoice preparation, delivery, and follow-up while keeping an existing time tracker.
Individuals and teams that want time, expenses, projects, reporting, and invoices in the same system.
Invoice creation
Import approved work, build a service invoice, preview the PDF and email, and choose manual or scheduled delivery.
Create standard invoices from tracked time, expenses, fixed fees, or free-form lines, with detailed or summarized supporting information.
Recurring schedules
Keep repeat sends visible in one queue with weekend-aware timing and a manual-send override.
Free-form recurring invoices can auto-send or save as drafts; time-and-materials recurring invoices generate drafts for review.
Reminder controls
Attach due-date and overdue follow-up to the invoice workflow, then pause or adjust it when a client replies.
Configure automatic late reminders; automatically sent free-form recurring invoices need reminder messages set on each template.
PDF and email delivery
Preview and test-send a branded email with its client-ready PDF attached before the real delivery.
Send a web invoice, share its link, export PDF copies, add a logo, and let clients view open invoices in a secure dashboard.
Payment collection
Add bank instructions or a hosted payment link from your chosen provider; InvoiceAgent does not process payments.
Connect Stripe or PayPal; Stripe can support recurring payments, while gateway and additional Harvest fees depend on the plan and method.
Time tracking
Import approved WakaTime or Toggl entries and group them into client-readable invoice lines.
Track time and expenses natively, apply project rates, monitor uninvoiced amounts, and generate invoices from those records.
Multi-currency behavior
Draft in a source currency, apply the latest available FX rate at send time, and lock it into the PDF.
Set account and client currencies, but Harvest does not convert amounts and supports only one currency per client, project, or invoice.
Accounting scope
Does not replace bookkeeping, reconciliation, tax, project budgets, expenses, profitability, or financial reporting.
Tracks time, expenses, budgets, invoice status, receivables, and profitability, and can copy invoices and payments to QuickBooks Online or Xero.
Setup effort
A seven-day trial focused on invoice rules, delivery, reminders, and one operational queue.
Requires clients, projects, tasks, rates, people, permissions, invoice defaults, gateways, and integrations for the full time-to-cash workflow.
Support and ecosystem
A focused product and help path; validate the complete invoice workflow during the trial.
A mature help center, web and mobile apps, more than 50 listed core integrations, onboarding resources, and enterprise support options.

Evaluation method
We compared the current public products across core audience, invoice creation, recurring schedules, reminder controls, PDF and email delivery, payment collection, time tracking, multi-currency behavior, accounting scope, setup effort, pricing, and support. We reviewed Harvest's official pricing, invoicing, recurring-invoice, payment, and currency documentation; we did not run a hands-on Harvest account test for this update.
Pricing snapshot
Harvest lists Free at $0 for one seat and two projects, Teams from $11 per seat/month or $9 per seat/month billed annually, Enterprise from $17.50 per seat/month or $14 per seat/month billed annually, and Enterprise Plus at custom pricing. Harvest says usage-based charges can apply for additional invoices, projects, clients, and tasks. InvoiceAgent lists $24 monthly, $240 annually, or $12 once for one non-recurring invoice; it does not process client payments.
Check before buying: Harvest plan names and pricing have changed from older documentation, and the current pricing page describes additional usage-based billing. Online-payment eligibility, gateway and Harvest fees, invoice behavior, integrations, and reporting vary by plan and country. Confirm the calculator and checkout total for your usage.

Questions to settle before you switch.
Can Harvest turn tracked time into an invoice?+
Yes. Harvest can create invoices from its native tracked time, expenses, and fixed-fee project data. It is the stronger fit when time capture and project reporting should be the system of record before invoicing.
Can Harvest automatically send recurring time-based invoices?+
Not in the same way as a fixed free-form invoice. Harvest documents that free-form recurring invoices can auto-send or save as drafts, while recurring invoices based on time and materials can only be saved as drafts for review.
Does Harvest convert currencies for international invoices?+
No. Harvest supports account and client currencies but documents that it does not perform currency conversion and allows only one currency per client, project, or invoice. InvoiceAgent is the clearer fit when a current FX rate should be applied automatically at send time.
