FreshBooks vs Keel: flat price, no client cap

You picked an invoicing app when you had two clients, and it was cheap. Then you landed a sixth, and the app asked you to upgrade — not because you needed a new feature, but because you crossed a line in a pricing table. That is the quiet math of per-client software: the bill goes up exactly when the work is going well. If you have been comparing FreshBooks and Keel to escape that, the difference is not a feature list. It is how each one decides what to charge you.

Why does FreshBooks get more expensive as I grow?

FreshBooks prices by billable clients. The entry-level Lite plan caps you at five. Add a sixth active client and you are moved up to Plus, which runs several times the Lite price. Nothing about the sixth invoice is harder to produce than the first — the cap exists to sort customers into tiers, not to reflect the cost of the work.

This is the pattern across account-based cloud tools: your price tracks a number the vendor meters — clients, invoices, seats, sometimes all three. The result is a bill that scales with your success rather than the value the tool delivers. A good month, where you sign three new clients, is also the month your software cost jumps. You are paying a small penalty for growing.

What is the “cancel lock-out” risk?

There is a second cost that never shows up on the pricing page. When your invoices, client list, and payment history live on a vendor’s servers, your continued access is a subscription, not a possession. Stop paying and your records can drop into a read-only state, sit behind an export window, or become hard to reach at exactly the moment you need them — tax season, an audit, a dispute with a client over what was billed.

The books describe your own business, but you rent the ability to open them. That is single-vendor dependence: a price change, a plan sunset, or a lapsed card can stand between you and your numbers. For a company of one, that is a real operational risk hiding inside a convenience.

How does on-device pricing change the math?

An app that runs entirely on your phone has no per-client server cost to recover, so there is nothing to meter against. No client count. No invoice quota. No per-seat fee. You send one invoice or two hundred; you bill three clients or thirty; the price does not move.

That is the whole point of flat pricing done honestly: it is flat because the architecture makes it flat, not because a plan happens to be generous this year. Your bookkeeping cost stops being a variable that grows with your business and becomes a fixed line you can forget about. Compare that to a per-client plan, where every new engagement quietly asks whether it is worth crossing the next pricing threshold.

What happens when you cancel?

Here the two models diverge completely. Cancel a cloud invoicing app and you are negotiating with a server for access to your history. Cancel an on-device app and nothing happens to your books, because they were never on a server to begin with — they are on your phone, where they have been the entire time. A lapsed subscription might turn off future premium features; it cannot reach back and revoke records you already own.

That distinction matters most in the moments that count. Your past invoices, client details, and totals are yours to open whether you are a paying subscriber this month or not.

Where Keel fits

Keel is priced the way an on-device app can afford to be: no client count, no invoice quota, no per-seat metering — one flat price, $7.99/mo or $59.99/yr, because the architecture has no server cost to meter against. Bill five clients or fifty and the number is the same, so growing never costs you extra. And because your books live in a private ledger on your iPhone, cancelling never revokes access to them — a paused subscription can only turn off future features, never the records you already keep.
