LotsInvoice vs Invoice Simple comes down to how you want to be charged and how much you bill. I'm the founder of LotsInvoice, so read this knowing I built one of the two. On LotsInvoice every plan has unlimited invoices, estimates and credit notes, and you pay per business you invoice from, with the whole team included. Invoice Simple's own help articles describe packages that cap invoices per month (3 on Essentials, 10 on Plus) with unlimited on Premium. Below is the side by side, with only facts I could open on their pages today.
The short version
- Pick LotsInvoice if you send invoices regularly and don't want a monthly cap, a per-seat price, or your layout limited to a template. You get a client portal and reminders, nine designs, and sent invoices that lock so the record stays honest.
- Pick Invoice Simple if you mostly invoice from your phone and want its app-first flow. Their help center calls it a "top-rated mobile app" and describes "tap, type and go".

Checked on 13 November 2026. Invoice Simple facts come from Essentials (article dated 14 January 2025), Plus (14 January 2025) and Premium (16 July 2023). Their pricing page returned a 403 to me, so I'm not quoting any Invoice Simple price. Check their pricing page yourself before you decide.
Where LotsInvoice wins
No invoice cap, ever. Inside a business, invoices, estimates, credit notes, customers, items, templates and team members are all unlimited. If a quiet month turns into a busy one, nothing changes on your bill.
The price follows your businesses, not your headcount. Starter is $12 a month or $120 a year for one business. Pro is $29 or $290 a year for five, and Business is $79 or $790 a year for twenty. If you'd rather not pick a plan, pay as you go is $15 per business a month. You can start with free credits and no card. The full breakdown is in LotsInvoice pricing explained.
The invoice looks the way you want. Rename, reorder, hide or add columns, add item codes and custom fields, use several taxes per line, and pick one of nine designs or a custom template. You preview the real PDF before anything goes out.
Sent invoices are locked. Once sent, an invoice is numbered and locked. You fix it with a revision and a reason, a credit note or a void, so the record you hand an accountant never quietly changes.
Clients pay you directly. LotsInvoice never holds or moves your money. Connect your own payment account, switch on online payment, and every sent invoice gets a Pay button for its balance. Your payment provider's usual fees apply and LotsInvoice adds nothing. I wrote up the options in how clients pay you with LotsInvoice.
Estimates that become invoices fast. Your client accepts an estimate by typing their name, and you turn it into an invoice in one click. Recurring invoices repeat every so many weeks, months or years, as drafts you check or sent on schedule. I compared estimate tools in the best estimate and invoice software, so I won't repeat that here.
Where Invoice Simple is strong
Invoice Simple is built around quick invoicing on a phone. Per its help center it offers QR code payments, read receipts that show when a sent invoice was delivered and read, a signature and photos on invoices, and saved clients and line items for repeat customers. If a small monthly volume and a mobile-first flow fit how you work, those are real strengths.
Which one should you choose?
If you bill a handful of times a month from your phone and the plan limits suit you, Invoice Simple is a reasonable fit. If you bill steadily, send estimates, have a team, or want your invoices to match a client's or accountant's format, I'd pick LotsInvoice. For a wider view, my guide to invoice software for freelancers covers free and paid options. You can see current plans on the LotsInvoice pricing page.
