Beautiful and simple, by default.

Open-source is freedom if you want to run a server and wire up the rest. Most freelancers just want a beautiful invoice that looks right and goes out, without the platform around it.

Left out, on purpose

Not a feature count for its own sake. Drupd wins where billing speed and the finished invoice matter, and steps aside where Invoice Ninja is doing a different, heavier job.

01The honest version

Invoice Ninja is a powerful open-source platform you host and configure, and Drupd is not trying to be. Drupd makes one bet: a beautiful invoice, sent in under three minutes, with nothing to deploy and nothing to set up.

Where Invoice Ninja hands you the parts, a theme editor, and a settings tree to climb, Drupd hands you a hand-typeset, true-A4 document that is already done. The platform Drupd leaves out is the reason there is nothing to configure, nothing to design, and nothing in the way of getting the invoice out.

02Side by side

The same work, two very different tools.

Sending the invoice
Time to first invoice
Drupd
5-step wizard with a live PDF and email preview. First invoice out in under three minutes.
Invoice Ninja
Fast on the hosted plan, but the self-hosted route means standing up a server before you bill anyone.
Invoice document quality
Drupd
Five handcrafted, typeset templates, server-rendered at true A4, with your brand color, logo, and crypto wallet icons set into the artifact. The finished invoice looks like a designer made it.
Invoice Ninja
A dozen templates and a theme editor, but a genuinely polished, professional-looking invoice is design work you do yourself before it looks the part.
Live preview while editing
Drupd
Real-time A4 preview that flips between the PDF and the outgoing email.
Invoice Ninja
Template preview, refreshed as you edit, but the PDF only, not the email your client receives.
Getting paid
Payment methods on the invoice
Drupd
Card link, bank transfer (IBAN, SWIFT, routing, BSB, IFSC), and crypto wallets (BTC, ETH, USDC, USDT, Solana, Tron).
Invoice Ninja
100+ gateways (Stripe, PayPal, Braintree, GoCardless, Mollie), each connected and configured by you.
Crypto wallets
Drupd
Five chains built in (BTC, ETH, USDC, USDT, Solana, Tron). Token and chain icons render in the PDF itself.

Invoice Ninja

Staying on top of it
Automated follow-ups

Up to 5 automated reminders with Friendly, Professional, or Firm tone, plus a real page-view signal, not just an email pixel.

An ember check marks the side that leads; a dash means that tool leaves it to the other, on purpose.

03Where it pulls ahead

Four reasons the switch pays off.

01 / Nothing to deploy

A server you never have to think about

Invoice Ninja is most powerful when you self-host it, which means a box to patch, back up, and keep online. Drupd is hosted and finished the moment you sign in. Your only job is the invoice.

02 / The artifact

Beautiful out of the box, no theming required

Five handcrafted templates, hand-typeset and server-rendered at true A4, carry your brand color, logo, and crypto wallet icons by default. No theme files, no CSS, no fiddling. The PDF a client opens is already a polished, professional document that looks like a designer made it, not a default you have to fix.

03 / Payments

Get paid without standing up a gateway

Paste a payment link, bank details, or a wallet address and you are collecting. Five crypto chains are native, with icons in the PDF, where Invoice Ninja stops at Bitcoin through a separate BTCPay server.

04 / Simplicity

One calm screen, not a platform to administer

No projects, no plugins, no gateway matrix, no settings tree to climb before you bill anyone. Drupd does invoicing, sending, and getting paid, and keeps the screen calm so the work goes out fast. Where Invoice Ninja is powerful because it does everything, Drupd is fast because it does one thing well.

04 · The price

$6/mo
Invoice Ninja$14/mo

Cheaper than Ninja Pro, hosted and finished, with no server bill or ops time hiding behind “free.”

The lowest price hereFree plan, no card
05The artifact

The invoice is the part your client sees.

Every other screen serves this one document, so we treat it as a thing worth crafting. Drupd hand-typesets each template and renders it server-side at true A4 — your brand color, logo, and payment details set with a designer’s care — so the invoice landing in your client’s inbox looks deliberate, polished, and unmistakably professional. Not generated. Made.

06Before you switch

Fair questions.

The honest answers, including the ones where Invoice Ninja is the better fit.

01

Invoice Ninja is free and open-source. Why pay for Drupd?

Free self-hosted means you run the server: deploy it, patch it, back it up, keep it online, then theme the invoice until it looks right. Drupd is $6/mo for the hosted, finished version, with a beautiful true-A4 invoice and a calm one-screen workflow out of the box and nothing to maintain, plus a genuinely free plan for unlimited invoices to three clients. You are paying for the absence of an ops job and a design job, not for the software alone.

02

Can I self-host Drupd like Invoice Ninja?

No, and that is deliberate. Drupd is hosted so it stays fast, secure, and up to date without any work on your side. If owning and running your own instance is a hard requirement, Invoice Ninja is the better fit, that openness is the whole point of it.

03

Does Drupd have an API like Invoice Ninja?

Yes. Drupd ships a Bearer-token REST API with idempotency keys and signed outbound webhooks. It is scoped to invoicing rather than the full self-hosted platform surface, but the building blocks for automation are there.

04

What about crypto? Invoice Ninja supports Bitcoin.

Drupd supports five chains natively, BTC, ETH, USDC, USDT, and Solana and Tron, with token and chain icons rendered right in the PDF. Invoice Ninja handles Bitcoin only, through a separate BTCPay Server integration you set up yourself.
