Which pricing model should I use for my product?
Subscription, one-time, lifetime, usage-based — the model is not a copy-the-competitor decision, it is a survival one. Each has a different shape: subscription earns recurring revenue but lives or dies on churn; one-time is clean cash with no lock-in but no recurring income; lifetime is a big payment now that becomes a liability if your costs keep running; usage tracks value but swings. Pick the model your product’s cost shape can actually carry — then check it on your numbers.
Don’t pick your model by copying competitors
It is the same mistake as copying their price. "Everyone in my space charges monthly, so I will too" ignores whether recurring billing fits your product and your costs. A tool someone uses once a quarter is a hard sell as a monthly subscription; a product with ongoing server and support cost bleeds on a one-time price. The model has to match your product, not the category’s default.
And if your product is not recurring in some form, it is not a SaaS — that is fine. The model still has to fit your costs.
The four models, and their survival shape
Subscription (recurring): the stronger business if people keep using it — recurring revenue compounds. But it lives on retention: churn is a constant tax, and a product people do not return to monthly churns hard.
One-time: you are paid once, cleanly — no lock-in, nothing to chase. It fits when the value lands once and there is little ongoing cost to serve. The trade: no recurring income, so growth rests entirely on new customers.
Lifetime: a big payment now for forever access. Tempting for the cash, but it is a liability — you owe service and cost for years against a one-off payment. Fine only if your cost to serve is near zero; dangerous otherwise.
Usage-based: the customer pays for what they use, so price tracks value — aligned and fair. But revenue is volatile and harder to forecast, and some buyers dislike the uncertainty ("can I just pay monthly instead of credits?").
Match the model to your cost shape (and the lifetime trap)
The clearest rule: ongoing cost → recurring price; one-off value → one-time price. If serving a customer costs you every month — servers, support, updates — a one-time or cheap lifetime price is a slow bleed: you keep paying to serve someone who paid you once.
That is the "$20 lifetime while everyone charges $13/mo" trap — it looks competitive and fills the bank today, then the hosting and support costs outlive the payment. Whatever you pick, it has to keep you default-alive — reaching profit before your cash runs out — as your costs grow, not just at launch.

FAQ
Is subscription always better than one-time?
No — subscription is the stronger business only if customers keep using and paying. If the value lands once, or usage is occasional, a one-time price can fit better and avoids churn entirely. Match the model to how your product is actually used.
Is a lifetime deal a good idea?
Only if your cost to serve is near zero. A lifetime price trades years of cost and support for a single payment — great for cash today, a liability if the costs keep running. Do the math before you offer it.
How do I choose between models?
Start from your cost shape, not the competitor’s default: ongoing cost points to recurring; one-off value points to one-time. Then check which model stays default-alive on your numbers.
