What is Harvest?
Harvest is a time-tracking and invoicing platform that helps professional teams log their hours, bill clients accurately and understand whether their projects are actually profitable. Used by more than 70,000 companies, it pairs simple, flexible time tracking with the reporting and invoicing tools service businesses need to turn logged hours into paid invoices.
What is Harvest?
At its core, Harvest makes it easy to capture time — with a timer, a manual timesheet or straight from your calendar — and attach it to the right client, project and task. From that data it generates invoices, tracks expenses, and produces reports on project profitability and team utilization, so a business can see not just how many hours were worked but whether that work made money.
Who it's for
Harvest is used across advertising, architecture, construction, law, accounting, consulting, design and software development, by teams of all sizes. It suits any business that bills for time or needs to keep projects on budget, from a solo consultant tracking billable hours to a large agency managing many concurrent client projects.
Key features
- Time tracking via timer, timesheet or calendar integration
- Expense logging with receipt attachments
- Invoicing auto-generated from tracked time and expenses
- Project profitability and team utilization reporting
- Budget tracking with alerts before you overrun
- Team capacity planning and timesheet approvals
- Clear project organization by client, project, task and tag
- Forecasting and scheduling via Harvest Forecast
From hours to invoices
Harvest's real payoff is how smoothly tracked time becomes revenue. Once hours and expenses are logged against a project, Harvest can turn them into a professional invoice automatically, and clients can pay online through integrations like Stripe. That removes the tedious, error-prone step of assembling invoices by hand at the end of the month and gets businesses paid faster.
Profitability and budgets
Beyond billing, Harvest is built to protect margins. Budget tracking warns you as a project approaches its limit, while profitability and utilization reports show which projects and people are pulling their weight. Multi-tiered billing rates — by person, project or task type, selected automatically — mean invoices reflect the right rate every time without manual adjustment.
Integrations and apps
Harvest offers more than 40 integrations with tools including Asana, Slack and Stripe, so time can be tracked inside the apps teams already work in and payments flow through familiar gateways. Desktop apps for macOS and Windows and mobile apps for iOS and Android mean time gets captured wherever the work happens.
Pricing
Harvest offers a free 30-day trial with no credit card required, and its paid plans scale with team size, so a solo user and a large agency each pay in proportion to how much they use it. The straightforward model keeps it accessible for freelancers while still serving bigger teams.
Capacity planning and approvals
For teams, Harvest adds the coordination layer that keeps projects on track: managers can plan capacity so no one is over- or under-booked, and timesheet approvals ensure the hours flowing into invoices and reports are accurate. Harvest Forecast extends this into forward scheduling, letting teams map out who will work on what in the weeks ahead and spot resourcing crunches before they happen.
Why choose Harvest
Harvest hits a practical sweet spot: time tracking that's simple enough that people actually do it, tied to invoicing and profitability reporting that turn those hours into paid, well-managed projects. For any business that bills for time or runs to a budget, it's one of the most trusted and approachable tools available.
What is Invoice Ninja?
Invoice Ninja is free, open-source invoicing and billing software built for freelancers, consultants and small businesses that need to look professional and get paid faster. Trusted by more than 200,000 businesses and running since 2014, it bundles invoicing, online payments, quotes, time tracking and expense management into one platform you can use in the cloud or self-host on your own server.
What is Invoice Ninja?
Invoice Ninja lets you create polished, branded invoices in minutes and send them to clients who can pay directly from the invoice in a single click. Around that core it adds the surrounding workflow most small businesses juggle across several tools: quotes and proposals, recurring and auto-billing, a branded client portal, expense and vendor tracking, and project management with Kanban boards.
Who it's for
The platform is a natural fit for freelancers, contractors, designers, developers, consultants and accountants — anyone who bills clients and wants a dependable, low-cost way to manage the money side of the business. The generous free plan makes it especially attractive for solo operators and new businesses watching every expense.
Key features
- Professional invoicing with customizable templates
- One-click online payments from the invoice
- Recurring and automatic billing
- Quotes, proposals and e-signatures
- Time tracking and Kanban-style project management
- Expense and vendor management
- A branded client portal
- Bank and credit-card transaction import
- Multi-factor authentication and PCI-DSS compliance
Payments and integrations
Invoice Ninja accepts payments through a wide range of gateways including Stripe, PayPal, Square and GoCardless, so clients can pay however they prefer. It connects with more than 50 services — QuickBooks, Gmail, Slack, Mailchimp and hundreds more — via Zapier, Make and Pabbly, and its API and self-hosting options make it a favorite among technically minded users who want full control of their data.
Open source and self-hosting
Unlike most billing tools, Invoice Ninja is open source with a public GitHub repository, and it can be self-hosted for teams that want to own their infrastructure and data outright. That transparency is a large part of why developers and privacy-conscious businesses gravitate to it.
Pricing
The Free plan is genuinely free forever and covers the essentials for a small client list, with no credit card required. Paid tiers add more templates, clients and advanced features: Ninja Pro at around $14/month, Enterprise at around $18/month, and a Premium Business tier for larger operations. A 30-day money-back guarantee backs the paid plans.
Getting paid faster
The whole product is oriented around shortening the gap between sending an invoice and receiving the money. Auto-billing charges recurring clients on schedule, payment reminders chase overdue invoices for you, and the one-click pay experience removes the friction that makes clients delay. Because customers can pay by card, PayPal or direct debit straight from the invoice, there are fewer excuses and fewer late payments.
Security and reliability
Invoice Ninja takes the money side seriously, with multi-factor authentication to protect accounts and PCI-DSS compliance for card handling. Self-hosting adds another layer of assurance for businesses that would rather keep financial data entirely on their own infrastructure, and the open-source codebase means the security model is transparent and auditable rather than a black box.
Why choose Invoice Ninja
Invoice Ninja's pitch is simple: professional invoicing and full billing workflow without the subscription bloat. The combination of a real free tier, open-source transparency, self-hosting and one-click payments makes it one of the best-value ways for independent businesses to bill clients and get paid on time. For freelancers and small teams who resent paying a premium just to send an invoice, it is one of the strongest options on the market.
