Review your expertise product after ninety days

A ninety-day product review should end with a decision: continue, narrow, improve, or retire the offer. Compare the money it brought in, the work it required, and the evidence that readers used your method. Then name what you still do not know.

For a nonfiction author, a paid companion can look promising in a sales report while quietly consuming the time reserved for the next book. It can also produce useful reader work before it earns enough to justify a larger investment. Neither situation becomes clearer by adding the numbers together into one score.

Use the worksheet below to review one offer. Ninety days is a convenient review interval, not proof that a business has succeeded or failed. If readers need six months to complete the task your book teaches, your first review must acknowledge that limitation.

Write down the audience, reader task, price, included help, and access period that buyers saw. Record any changes during the quarter. A product sold with personal feedback is a different offer from the same material sold for independent use.

Keep the product separate from your broader author business. Book royalties, speaking fees, and consulting income may matter to your livelihood, but they cannot demonstrate that this particular companion works. Record a consulting inquiry as an inquiry; count a resulting sale separately if you can substantiate the connection.

For this review, the central question is: Does this offer deserve another bounded investment of my time and money? That gives you permission to keep a small useful product small.

Use actual records where available. Write “unknown” where they are missing, and identify the record you would need. Do not quietly replace missing evidence with an estimate.

Keep expense categories consistent with your bookkeeping. In his SBA article on sales forecasting, Tim Berry recommends matching planning categories to accounting categories so that planned and actual figures can be compared. A review loses usefulness when every quarter rearranges the numbers.

This worksheet is a management aid. Its simple cash remainder is not a complete profit calculation: taxes, shared overhead, earlier development costs, unpaid work, and future obligations may all matter.

Split initial construction from recurring work. Then identify which recurring tasks grew because you added buyers and which happened regardless of buyer count.

In a historical Reddit discussion, creator u/jadekinsjackson described their experience this way:

“It’s doubled and tripled the workload for me, I’ll probably be getting rid of it.”

That is an individual account about a Patreon offer, not a forecast for your product or a claim about the platform today. It is a useful reminder to ask whether additional income came with an acceptable workload. Original comment.

Also count the work of finding buyers. In a separate discussion about hiring marketing help, writer and game developer u/DrakeyFrank said:

“I would seriously prefer to focus on my work rather than doing all the marketing gimmicks.”

The post asks about outsourcing; it does not establish that hiring someone would pay off. Your review should record promotion hours whether you performed the work or paid someone else to do it. Original discussion.

If you did not track hours, reconstruct them from your calendar and label them estimates. For the next period, use the support-time worksheet to separate reader help from product improvements and record the work consistently.

Everything in this example is fictional. Prices, costs, reader accounts, and decisions are illustrative; they are not Skillfully results or fees.

Julian wrote a nonfiction book about sequencing documentary photo essays. His paid companion helps readers arrange a twelve-image narrative and explain the role of each image. It does not include personal editing or a promise of publication.

He reviews its first ninety days:

The $810 is cash remaining after the listed expenses, before author compensation, taxes, and any omitted costs. It is not spendable proof of profit, especially while access remains promised.

The 42 hours also need interpretation. Twenty-four were initial construction; eighteen were support, promotion, and maintenance. Dividing the quarter’s cash remainder by all hours would obscure that distinction. Equally, assuming construction will never recur would ignore future revisions.

Six shared sequences are evidence that six responding buyers produced something. They do not establish that all thirty buyers succeeded, or that the companion caused an improvement. The twenty nonrespondents remain unknown. Julian also has not checked whether readers used the resulting sequence in a real project.

The reported acquisition routes describe what buyers remember. They do not prove that the photography club caused seven incremental sales or that buying advertising would produce similar results.

Julian chooses narrow. Of the ten respondents, four asked for help with projects much longer than twelve images. Three of those four also requested individual critique. His support log connects most of the eight support hours to explaining those boundaries.

For the next thirty days, he will clarify the twelve-image use case before purchase and add one complete example showing the limits of the exercise. Existing buyers retain the access and support already promised. He will spend no more than four additional author hours and $100 on this test.

His decision note reads:

Continue the twelve-image offer for one more review period. Clarify its scope, preserve existing commitments, and collect permission-based accounts of what readers did with their sequences. Do not add personal critique or a new subscription tier.

This is a test of a plausible explanation, not a finding that the narrower offer will sell better. At the next review, Julian will compare new support requests, refunds, relevant purchases, and reader examples with this baseline. Small numbers will remain inconclusive; the purpose is to improve his decision, not manufacture statistical certainty.

Continue when the offer fits your capacity, readers show useful application, and the economics justify maintaining it at its current size. Set the next review date even if you change nothing.

Improve when appropriate readers repeatedly encounter a specific, repairable obstacle. Define the repair and the evidence you expect to inspect afterward. Avoid rebuilding the entire product because two people asked for unrelated features.

Retire when the offer cannot meet its promise within acceptable effort, or when you no longer want to maintain it. Plan what happens to existing access, outstanding help, and any refunds before closing new sales. Stopping new purchases does not itself complete old commitments.

If the evidence is simply too thin, choose a limited extension with an explicit question. “Keep going until it works” is not a review decision. “Spend two hours learning why five suitable buyers have not attempted the exercise” is.

Complete the worksheet before adding another offer. If it points toward helping readers apply one clearly bounded method, bring that method and your review notes to Skillfully and select Book onboarding to discuss the next step.
