Best Invoicing Apps for Freelancers (2026)

Invoicing software is the first finance tool most freelancers buy, and it's also where they waste money. You need three things: professional invoices, a way for clients to pay online, and a record of who has paid. Everything beyond that — proposals, contracts, time tracking, full accounting — is optional. This guide ranks six real options by how well they cover those basics for a solo freelancer and what they actually cost.

Quick verdicts

1. Wave — best free invoicing for most US freelancers

Wave's Starter plan is $0 and lets you create unlimited estimates and invoices. Online card payments on Starter are 2.9% + $0.60 per Visa/Mastercard/Discover transaction (3.4% + $0.60 for Amex). The Pro plan ($19/month or $190/year, per Wave's pricing page) adds automation and a discounted rate: 2.9% + $0 for the first ten cumulative transactions each month, then the standard rate. Verdict: if you invoice a handful of clients a month, start here. The free plan is the real product, not a trial.

2. Invoice Ninja — best budget and open-source option

Invoice Ninja's Free plan is "forever free" for up to 5 clients. Ninja Pro is $14/month or $140/year and removes the client limit; Enterprise starts at $18/month for 1–2 users. You can also self-host the open-source version. Verdict: great value and very flexible; the interface is busier than Wave's.

3. Zoho Invoice — free and polished

Zoho markets Zoho Invoice as free. We couldn't extract plan limits from its pricing page automatically, so check the current limits on Zoho's site before committing. Verdict: a strong free choice, especially if you already use Zoho Mail or Zoho Books.

4. FreshBooks — easiest all-in-one, but costs add up

FreshBooks lists Lite at $23/month, Plus at $43/month, and Premium at $70/month, and usually runs steep introductory discounts (on October 13 it showed 80% off for three months). Card payments are 2.9% + $0.30 on most cards; ACH bank transfers are 1%. Extra team members are $11/month each, and Advanced Payments is a $20/month add-on on lower plans. Verdict: the friendliest experience with time tracking and expenses built in. Budget for the full list price after the promo ends.

5. Bonsai — best if you also need proposals and contracts

Bonsai's Basic plan is $15/user/month ($9 billed annually); Essentials is $25 ($19 annually), Premium $39 ($29 annually), and Elite $59 ($49 annually). Verdict: worth it if proposals and e-signed contracts are part of your sales process. Overkill if you only need invoices.

6. HoneyBook — for creatives with client workflows

HoneyBook bundles booking, contracts, and payments for client-heavy creative businesses (photographers, planners). Check its pricing page for current plans. Verdict: excellent for that niche; developers and writers will pay for features they won't use.

How to choose

Start with the cheapest tool that gets you paid online. If you send under ten invoices a month and are in the US or Canada, Wave's free plan is hard to beat. If you need more clients on a free plan or want to self-host, use Invoice Ninja. Upgrade to FreshBooks or Bonsai only when time tracking, proposals, or contracts would save you real hours. Remember that payment processing fees usually cost more than the subscription itself: at 2.9% + $0.30, a $2,000 invoice paid by card costs about $58.30, while ACH is often cheaper.
