How we write these. Every comparison page on this site names what the other product does better, in its own section, first. Not as a courtesy — because a comparison page where the competitor loses every round is a page no one believes, and because you are going to find out anyway the moment you download the thing. Prices are taken from the competitor's own pricing page and stamped with the date we checked them.
What Invoice Simple does better than Toolbelt
Android and web
Same story as Joist. Invoice Simple is everywhere; Toolbelt is iPhone-only.
Dead simple for non-trades
It is a general-purpose invoice maker and it is very good at that. If you are a freelancer or a shop owner rather than a contractor, its generic approach is a feature, not a bug.
Longer track record
It has been around a long time with a large user base and the stability that implies.
What Toolbelt does better than Invoice Simple
Built for trades, not for everyone
Invoice Simple is a general invoice app. It has no concept of a quote that becomes an invoice when the job is won, no trade line items, and nothing that understands a job site.
Voice input and AI descriptions
Describe the work in your own words; Toolbelt writes it up properly. Invoice Simple gives you a blank text box.
Offline by design
Toolbelt is built to work with no signal at all.
Flat, published price
$14.99/mo or $99.99/yr, all features. No tier maze.
Invoice Simple pricing
We are not going to print a price for Invoice Simple, and here is why.
Invoice Simple's pricing page blocks automated access, and the third-party sites that quote it disagree with each other — we saw the entry tier listed at both $4.99 and $6.99 a month. Rather than print a number we cannot stand behind, we are linking you to their page. Check it yourself; that is what we would do.
Check it yourself: Invoice Simple pricing. We would rather send you to the source than publish a number we cannot stand behind — a comparison page with a wrong price in it is worth less than no comparison page at all.
Toolbelt pricing
| Toolbelt plan | Price | What you get |
|---|---|---|
| Free | $0 | 3 invoices or quotes per month, every feature on, no card required |
| Monthly | $14.99/mo | Unlimited invoices and quotes, voice input, AI descriptions, offline, custom PDF templates |
| Yearly | $99.99/yr | Same as monthly, cheaper per month |
Platforms: iPhone only. Invoice Simple runs on iOS, Android, web. That is a real gap and it is the first thing on this page you should weigh — if you are on Android, this decision is already made for you.

What neither of us does well
Worth saying plainly, because every comparison page on the internet pretends its two subjects cover the whole world between them. Neither Toolbelt nor Invoice Simple is a substitute for an accountant. Neither will chase a customer who has decided not to pay you. And neither one fixes a pricing problem — if your rates are too low, better invoices will just help you go broke more efficiently. If that is the real issue, start with our hourly rate calculator instead of either app.
Should you switch — and how?
The reason people move from Invoice Simple to Toolbelt is almost always the same: they started as a general small business and became a trade business. Invoice Simple is built to invoice anything. Once your invoices are consistently 'labour, materials, call-out, deposit', a generic tool starts adding friction on every single document.
Switching costs you nothing but setup time. There is no migration — your sent invoices live in your email and your accounting, not in the app. Set up your business profile, save the six or seven line items you actually use, and run one job through Toolbelt end to end before you commit to it.
The honest verdict
Invoice Simple if you need Android or web, or if you are not really a contractor. Toolbelt if you are in a trade, on an iPhone, and want the app to understand what a quote and a job site are.
Common questions
Is Toolbelt cheaper than Invoice Simple?
Toolbelt is $14.99/month or $99.99/year for everything, with a free tier of 3 documents a month. We could not verify Invoice Simple's current pricing from their own site, so we are not going to claim we are cheaper without checking. Their pricing page is linked above.
Can I use Toolbelt if I'm on Android?
No. Toolbelt is iPhone only. If your phone is an Android, Invoice Simple covers you and we do not — that is the end of the decision, and no feature table changes it.
Does Invoice Simple have voice input or AI descriptions?
Not as of 2026-07-12, based on their published feature set. This is the clearest functional difference between the two products: with Toolbelt you speak the work and it gets written up as line items.
Do I have to migrate my old invoices?
No, and you generally should not bother trying. Invoices you have already sent live in your email, your accounting and your customers' inboxes — they are valid documents wherever the app that made them ends up. Set up your business details and your common line items, and start with your next job.
