Fix the unit and time horizon: When Agency should move to Unlimited
The agency has eight production hostnames today, but client wins, cancellations, and migrations change the count every month. A defensible cost model for when Agency should move to Unlimited fixes the period, currency, denominator, and service scope before combining any numbers.
Eight active production hostnames, two replacements a month, and four additions expected this quarter create a maximum of 12 simultaneous production hostnames even though today's count is only eight. The worked example for when Agency should move to Unlimited should show the arithmetic and the assumption that would change the decision, rather than presenting one precise forecast as certainty.
Calculate the decision-changing case: When Agency should move to Unlimited
Model current sites, three-, six-, and 12-month maximums, monthly replacements, approval labor, delayed onboardings, expected client revenue, and the annual plan difference. Every input to when Agency should move to Unlimited needs a dated source and must distinguish an in-product estimate from a finalized provider charge or an observed business outcome.
Base the threshold on peak active hostnames, expected replacements, and administration time—not only today's count. The operating boundary is explicit: Begin Unlimited evaluation when the fleet may exceed Agency's 10-hostname allowance or when replacement and delay labor exceeds the plan difference. Model when Agency should move to Unlimited as a range, then ask whether the selected action remains reasonable at both the low and high ends.
- Evidence set — Model current sites, three-, six-, and 12-month maximums, monthly replacements, approval labor, delayed onboardings, expected client revenue, and the annual plan difference.
- Decision boundary — Begin Unlimited evaluation when the fleet may exceed Agency's 10-hostname allowance or when replacement and delay labor exceeds the plan difference.
- Completion check — Would the decision about when Agency should move to Unlimited stay the same if the uncertain input moved to the other end of its range?
Include hidden operating cost: When Agency should move to Unlimited
Choosing from the year-end count ignores temporary overlap, migration windows, and sites awaiting cancellation during the busiest month. The common modeling error in when Agency should move to Unlimited is to compare a visible subscription or AI charge while valuing staff work, outage, or false stops at zero.
Count active sites; add known starts and overlaps; calculate maximum simultaneous need; price administration and delayed sales; compare $299 Agency with $499 Unlimited; approve the trigger and review date. Follow the calculation order for when Agency should move to Unlimited without mixing monthly and annual values, and rerun it when the denominator or model price changes.
Choose a review boundary with Agency-to-Unlimited Migration decision sheet: When Agency should move to Unlimited
For when Agency should move to Unlimited, Agency covers up to 10 normalized production hostnames and Unlimited removes the managed production-hostname count ceiling; neither plan makes provider usage unlimited, and current terms for staging, .local, .test, resale, hosting bundles, and client-managed sites still govern the use case.
Use the sheet behind a permanent Unlimited upsell in the Agency dashboard so sales and operations evaluate the same evidence. Use the Agency-to-Unlimited Migration decision sheet with one authoritative dashboard record for company, production URL, owner, contract state, approval, replacement, and verified revocation instead of copying access codes or keeping competing spreadsheets.
Forecast the fleet before the eleventh hostname arrives
Today's count hides signed work that has not launched, likely wins, expected exits, and temporary migration overlap. Build both a probability-weighted forecast and a peak case. The weighted figure supports budgeting; the peak case shows whether the Agency limit of 10 normalized production hostnames could be exceeded even briefly.
In the worked example, eight current sites plus weighted wins, exits, and migration overlaps produce an expected concurrent need of 10.9 hostnames; the full peak case reaches 17. Four replacements at $60 of internal labor also cost $240, which is greater than the current $200 annual difference between Agency at $299 and Unlimited at $499. These are planning assumptions, not product facts, and should be replaced with the agency's pipeline probabilities and loaded labor rate.
Crossing 10 changes the capacity question; reaching a cost crossover changes the economic question. Evaluate Unlimited before the capacity is exhausted when either the probability-weighted need is above 10 or avoidable administration and delay cost exceeds the plan difference. Record the assumption that would reverse the choice and recalculate monthly.
- Evaluate Unlimited now in this example: expected need exceeds 10 and modeled labor exceeds the $200 plan difference.
| Fleet movement | Count | Probability/weight | Weighted contribution |
|---|---|---|---|
| Current active production hostnames | 8 | 100% | +8.0 |
| Likely client wins | 5 | 60% | +3.0 |
| Expected exits | 3 | 70% | −2.1 |
| Temporary migration overlaps | 4 | 50% | +2.0 |
| Probability-weighted concurrent need | 10.9 | ||
| Full peak if all starts and overlaps coincide | 8 + 5 + 4 | 17 | |
| Replacement labor | 4 × $60 | $240 | |
| Annual plan difference | $499 − $299 | $200 |
Use actuals for the next model: When Agency should move to Unlimited
After one operating period, replace the assumptions for when Agency should move to Unlimited with actual volume, labor, outcomes, and the provider invoice, retaining the original forecast for comparison. The completion question is: “Would the decision about when Agency should move to Unlimited stay the same if the uncertain input moved to the other end of its range?” Record the answer, the remaining uncertainty, the owner, and the next review date rather than treating an executed action as a completed outcome.
The Agency-to-Unlimited Migration decision sheet should make when Agency should move to Unlimited an auditable choice: inputs, arithmetic, uncertainty, decision boundary, owner, and next recalculation date. For when Agency should move to Unlimited, that record creates a natural next step: test the chosen boundary on one supported, reversible WordPress path, confirm the customer fallback, and expand only when the evidence still supports the decision.
