Zoho Invoice vs Invoice Ninja: Two Free Tools, Two Opposite Limits
Disclosure: Neither tool pays us anything. We have no affiliate relationship with Zoho or with Invoice Ninja and have applied to neither. Both are genuinely free products, which means there is very little money anywhere in this comparison — including for us.
These are the two most genuinely free invoicing tools we have costed. Neither has a plan fee, neither takes a percentage of your money, and both will run a small business indefinitely at $0. They are limited in exactly opposite ways, and the difference between them is not a feature list. It is which limit you will hit first.
The short answer
Many clients → Zoho. Few clients, many invoices → Invoice Ninja. And if invoices go unpaid, Zoho, by a distance.
- 👥Invoice Ninja caps you at 5 clients, unlimited invoices. Zoho has no client limit but caps invoices per year.
- ❔Zoho will not publish its invoice cap. You can only see the number from inside your own account, under Settings > Usage Stats.
- ⏰Automated payment reminders: free on Zoho, $140 a year on Invoice Ninja. That is the feature that decides whether “free” is actually free.
- 🏷️Invoice Ninja prints its own name on your invoice until you pay. Zoho does not.

The two limits are mirror images
| Zoho Invoice | Invoice Ninja Free | |
|---|---|---|
| Plan fee | $0 | $0 |
| Cut of your payments | 0% — it does not process payments | 0% — you connect your own gateway |
| Clients | No limit | 5 |
| Invoices | Capped per year — number not published | Unlimited |
| Automated payment reminders | Included | Pro only — $140/yr |
| Recurring invoices | Included | Included |
| Custom templates and your branding | Included | Included |
| Vendor’s name on your invoice | No | Yes, until you pay |
| Self-hosting | No | Yes — Elastic License 2.0 |
Put the two constraints side by side and the choice becomes arithmetic rather than taste.
Count two things about your business.
How many separate people will you invoice this year? Over five → Invoice Ninja’s free plan is out.
How many invoices will you send? Into the hundreds → Zoho’s unpublished cap becomes a risk.
A consultant with three retainers billing monthly — 36 invoices, 3 clients — fits comfortably inside both. A tutor with forty students fits only Zoho. A designer with two clients and two hundred small invoices fits only Invoice Ninja.
Zoho’s refusal to publish the cap deserves naming. Its own FAQ says the number of invoices is “subject to usage limits that are updated every year” and directs you to Settings > Usage Stats inside your account to see it. Third-party comparison sites variously claim 500, 1,000 and 1,500 a year; none of them can be sourced to Zoho. That is a genuine mark against an otherwise excellent free plan: you cannot plan around a number you are not allowed to see until after you have committed.
Invoice Ninja’s five is published, hard and easy to plan around. A worse limit, honestly stated, is easier to work with than a generous one kept secret.
Only one of them chases a late payer
This is the line that decides it for most people, and it is easy to miss because both tools list “reminders” somewhere.
Zoho Invoice includes automated payment reminders at $0. Invoice Ninja puts them behind Pro at $140 a year. And in our own breakdown of Invoice Ninja we concluded that reminders are the single strongest argument for paying for that product — one rescued invoice covers the subscription.
Which means: Zoho gives away, at zero, the feature that justifies Invoice Ninja’s entire subscription.
Whose name is on your invoice
Invoice Ninja’s free plan prints “Created by Invoice Ninja” on the documents you send clients. You can add your own logo; you cannot remove theirs without Pro.
Zoho does not do this. Custom templates and your own branding are included on the free plan, with no vendor mark to remove.
How much that matters depends entirely on who receives the invoice. To a regular client who knows you, invisible. To a procurement department at a company three times your size, it says something about you that you may not have chosen to say. That is the honest trade: Invoice Ninja’s free tier is partly funded by advertising on your paperwork, and Zoho’s is not.
What Invoice Ninja offers in return is breadth. Its free plan lists projects, billable time tracking, Kanban boards, expenses, vendors, inventory and deposits — a wider product than invoicing alone. If you would otherwise pay for a separate time-tracking tool, that changes the sum.
Which one are you?
Which one are you?
👥 I invoice more than five different people
Zoho Invoice. Invoice Ninja’s free plan is out at client six and the fix is $140 a year. Zoho has no client limit at all.
⏰ Clients pay me late and I hate asking twice
Zoho Invoice, decisively. Automated reminders are included at $0 and cost $140 a year at Invoice Ninja. This is the feature that gets you paid; do not pay for it if you do not have to.
🧾 Two or three clients, but hundreds of small invoices
Invoice Ninja. Unlimited invoices to five clients, and Zoho’s unpublished annual cap is exactly the risk you would be running. You will want Pro for the reminders eventually — budget $140.
🏢 My clients are large companies
Zoho, on branding alone. An invoice that says “Created by Invoice Ninja” is a small thing that lands badly in a procurement inbox. Or budget Invoice Ninja Pro at $140 from the start rather than sending fifty branded invoices first.
🖥️ I want to run it on my own server
Invoice Ninja — free to self-host under the Elastic License 2.0, no client cap. Zoho does not offer this. Get the white-label licence price in writing first; it is a separate recurring charge and is not published.
What we could not verify
Zoho’s invoice cap. Zoho does not publish it. We are not going to repeat the 500 / 1,000 / 1,500 figures circulating on comparison sites as though they were sourced, because they are not. If you expect high invoice volume, open Settings > Usage Stats on day one and find out before you build on it.
Feature-by-feature parity. We compared what each vendor publishes. Invoice Ninja lists projects, time tracking and inventory on its free plan; we did not establish whether Zoho’s free plan matches each of those, so the table above does not claim either way.
Invoice Ninja’s white-label licence. It exists, it is annual and recurring, and its price is not published on the self-hosting terms page.
The thing that actually decides it
Not which is more generous. Both are unusually generous, both are genuinely $0, and both take nothing from the money your clients send you — which, after costing a dozen tools that do, is worth saying plainly.
What decides it is which of two numbers you know about your own business: how many people you bill, and how many times you bill them. Over five people, Zoho. Hundreds of invoices to a handful of people, Invoice Ninja.
And if you are genuinely on the fence, the reminders settle it. One tool chases your money for free and the other charges $140 a year to do it. On a page about two free products, that is the only $140 in the room.
