Question 1

Is Simple Invoice Generator really free?

Accepted Answer

Yes. You can create up to three invoices completely free, with no credit card required and no expiry date. The free plan is designed for freelancers who are just getting started or who only send invoices occasionally. On it you can build a complete, professional invoice — your logo, business and client details, itemised line items, taxes, discounts, and payment terms — then export it as a PDF or email it directly to your client. The three-invoice limit applies to your whole account, so once you have created three, you would upgrade to the Pro plan to keep going. Pro costs $9 per month or $79 per year and removes the invoice limit entirely while keeping every feature, including client management, invoice tracking, email sending, and multi-currency support. There is no long-term commitment — you can upgrade, downgrade, or cancel at any time from your account settings.

Question 2

Can I use this as a freelance invoice generator?

Accepted Answer

Absolutely — Simple Invoice Generator is built specifically for freelancers, contractors, consultants, and small businesses. You can create a polished invoice in just a few minutes: add your details and logo, list your services or hours with rates, and the totals calculate automatically. It works well across professions, whether you are a graphic designer billing for design concepts and revision rounds, a photographer charging for sessions and licensing, a web developer invoicing hourly work and project milestones, or a consultant billing retainers and expenses. You can save each client's details once and auto-fill them on future invoices, track whether each invoice is draft, unpaid, paid, or overdue, and email invoices to clients directly from the app with the PDF attached — on both the free and Pro plans. There is no accounting knowledge required and nothing to install, so you can send your first professional invoice in the same sitting.

Question 3

Can I export invoices to PDF?

Accepted Answer

Yes. Every invoice you create can be exported as a professional PDF with a single click, on both the free and Pro plans. The generated PDF includes everything a client expects to see: your logo and business details, the client's information, a clear invoice number, issue and due dates, itemised line items with quantities and rates, any taxes or discounts, and the total amount due. The layout is clean and print-ready, so it looks professional whether your client views it on screen or prints it out. You can download the PDF to keep for your own records or to upload elsewhere, or you can email it to your client directly from the app, with the PDF attached automatically. Because the invoice is generated from your saved company and client details, your branding stays consistent across every invoice you send, without having to reformat anything each time.

Question 4

What currencies are supported?

Accepted Answer

Simple Invoice Generator supports eight currencies: US Dollar (USD), Euro (EUR), British Pound (GBP), Swiss Franc (CHF), Canadian Dollar (CAD), Australian Dollar (AUD), Japanese Yen (JPY), and Serbian Dinar (RSD). You can set a different currency for each individual invoice, which makes it practical if you work with international clients or bill customers in more than one country. The chosen currency symbol and formatting are applied automatically to the line items, subtotal, taxes, and total on both the on-screen invoice and the exported PDF, so everything displays correctly for your client. This is useful for freelancers and small businesses that take on cross-border work — for example, a designer based in Europe billing a client in the United States, or a consultant invoicing across several markets — without needing separate tools or manual currency formatting for each invoice. Multi-currency support is available on every plan.

Question 5

Can I send invoices directly to clients?

Accepted Answer

Yes. You can email invoices to your clients directly from within the app on both the free and Pro plans, with the invoice attached automatically as a PDF, so there is no need to download the file and attach it to a separate email yourself. The email is sent from the app to the client address you enter, which keeps your invoicing workflow in one place and saves a few steps on every invoice you send. On the free plan this works within the three-invoice limit; upgrading to Pro removes that cap so you can send as many as you need. Sending directly from the app is particularly handy once you are invoicing regularly, because it removes the repetitive download-and-attach step and helps your invoices reach clients quickly and consistently. As with the rest of the app, your saved company details and branding are applied automatically, so every invoice looks professional.

Question 6

Is my data safe?

Accepted Answer

Your invoices and client data are stored securely in Google's Firebase infrastructure, the same platform the app is built on. Access is tied to your account, so your invoices, clients, and settings are only available when you are signed in — other users cannot see your data. We do not sell your data to third parties. Because everything is saved to your account in the cloud rather than to a single device, your information stays available when you switch between your desktop, tablet, and phone, and you do not risk losing invoices if a device is lost or replaced. You stay in control of your own records: you can edit or remove invoices and client details at any time from within the app. If you ever stop using the service, your account data remains yours to manage. Keeping your business information private and under your control is a priority for the app.

Question 7

Can I cancel my Pro subscription anytime?

Accepted Answer

Yes. You can cancel your Pro subscription at any time from your account settings — there is no long-term contract and no cancellation fee. When you cancel, your Pro features remain active until the end of the billing period you have already paid for, so you do not lose access immediately; after that, your account simply returns to the free plan. Your existing invoices and client data are not deleted when you downgrade — they remain in your account, and you can continue viewing and exporting them within the limits of the free plan. If you later decide you need to remove the invoice limit again, you can re-subscribe to Pro at any time and pick up where you left off. This flexibility means you can move between the free and Pro plans as your invoicing needs change from month to month, without being locked in.

Question 8

Do I need to install anything?

Accepted Answer

No — Simple Invoice Generator runs entirely in your web browser, so there is nothing to download and nothing to install. It works on desktop, laptop, tablet, and mobile, so you can create or send an invoice from wherever you happen to be, whether that is at your desk or on the go straight after finishing a job. Because it is browser-based, there are no updates to manage and no software taking up space on your device; you simply sign in and your invoices, clients, and settings are there. Your company details, logo, default notes, and payment terms are saved to your account, so they pre-fill automatically on every new invoice and stay consistent across devices. This makes it a lightweight alternative to traditional desktop accounting software — you get professional invoicing without the setup, installation, or learning curve those larger tools usually require.
