Will this revenue come back next year?

A business can show steady sales because customers renew a contract, reorder when they need more, or approve another project. Those patterns can look similar in a year-end report. They carry different risks when a buyer is asking how much of this year's revenue is likely to be there after close.

So when a teaser or management presentation calls revenue recurring, start with a plain question: what has to happen for the customer to pay again? The answer should point to a contract, a buying habit, or a new decision. The label alone does not tell you which one.

Find the reason the customer pays twice

A service agreement may require a customer to pay each month or year until renewal or cancellation. A distributor may see the same customer place regular orders without any promise to do so. A contractor may return to a customer for separate jobs, each of which needs its own approval. All three businesses can have repeat sales. Only one may have a signed obligation covering the next period, and even a contract can carry cancellation or renewal risk.

This distinction matters at the first screen. A buyer who treats every repeat customer as contracted revenue may give too much weight to sales that still depend on a fresh purchase decision. A buyer who dismisses every uncontracted sale may miss a stable pattern that is supported by customer history. The goal is to describe what is actually known.

Separate contracts, repeat orders, and projects

Contracted revenue has an agreement behind it. Read what is being delivered, how long the term lasts, when renewal comes up, and how either side can end or change the arrangement. A renewal date on the calendar is not the same as a guaranteed renewal. Ask whether pricing can reset and whether the customer can reduce scope.

Repeat orders come from customers who have bought before, but each order may be optional. The useful question is whether customers return on a pattern that can be seen in the records. Look at the same customer group over time, not just this year's total. A large one-time order from an old customer should not quietly become an annual run rate.

Project revenue depends on each new award or approval. A company may have several projects with the same customer, but the next project still has to be won. Keep signed work, work in progress, and early pipeline in separate buckets. Backlog can help show what has been ordered; it does not make later projects automatic.

Read the definition behind the headline number

If the materials include recurring revenue, annual recurring revenue, or a similar measure, ask how the company calculated it. Which customers and services are included? Does the figure include unsigned renewals, implementation work, usage charges, or one-time projects? What period does it cover, and what changed since the prior period?

The label can mean different things from one company to another. In its 2026 filing, public software company Amplitude says it is not aware of a uniform standard for calculating key business metrics. It defines ARR using customer contract terms, says it is not the same as annualized GAAP revenue, and warns that it is not a revenue forecast. The filing does not set a rule for private-company acquisitions. It is a useful example of why a buyer should read the company's own definition before using a headline metric. See Amplitude's 2026 Form 10-Q.

Check the customer list and the renewal calendar

A first pass does not need to rebuild every invoice. Start with a customer-level schedule that shows sales over a few periods, the type of work, and the source for each figure. For contracts, add the end date, renewal terms, cancellation rights, and any known price changes. For repeat orders, show which customers returned and when. For projects, keep awarded work apart from proposals and early conversations.

Then look for the few customers or dates that could change the decision. Several agreements expiring at once may deserve attention even if the annual total looks steady. A customer buying every month may be worth a closer look if one product or location drives most of the volume. Keep confirmed facts separate from the questions that still need an answer.

Ask what profit comes with the repeat sale

Repeatable sales are not automatically repeatable profit. A maintenance agreement may require more technician hours than the price allows. A reorder may depend on materials whose cost has changed. A project can bring revenue but also need new equipment, subcontractors, or working capital. Check what it costs to serve the customer and whether the reported margin holds across periods.

This is where the first-screen question becomes useful to the investment decision. The buyer is not only asking whether a sale could happen again. The buyer is asking what has to be true for it to happen, what it costs to deliver, and whether the answer fits the acquisition plan.
