There is no single correct answer for everyone, but there is a right approach for each business.
Sufficient retainer hours align with the actual output rhythm of the business, plus a contingency for reviews and incidents. The safest approach is to count the brand workload from the last three months, then add a buffer for peak times and urgent tasks. Starting at a reasonable level and adjusting based on reality is better than purchasing an excess of unused retainer hours.
There is no standard number that applies to all businesses. The sufficient hour fund is the one that aligns with your actual operational rhythm: the number of publications needed, the number of touchpoints that need to be maintained, plus a buffer for reviews and incidents. Choosing based on budget intuition often leads to one of two wasteful outcomes: over-purchasing and having excess hours every month, or under-purchasing and not having enough hands during peak times.
Before choosing a rate, you need to answer these five questions:
These five questions provide a true picture of the volume. If you cannot answer them, any number of hours chosen will just be a guess.
The simplest method is to look back at the last three months. Count the actual publications released, the number of times corrections or folding issues had to be addressed, and the number of review sessions for identity. Convert this into estimated hours, then add about 15 to 20 percent for unforeseen tasks like adjustments after customer feedback or sudden message changes.
DesignOps (design operations management) considers prioritization and workload management as a separate function. The time budget needs to be sufficient for both coordination and maintaining standards, not just for pure production of deliverables. If you only account for production hours, you will always feel a lack without understanding the reason.
A retainer (maintenance contract) locks in service capacity for clients. Both parties should size it according to actual volume to avoid wasting empty slots or being short-handed during peak times.

Small level is appropriate when: the volume is consistent and stable, with few product lines, and the internal team handles most of the work, while the studio mainly maintains standards and supports when needed. Sinh Vũ refers to this as the Essential level in the O1 structure, corresponding to about 80 hours per month.
Moderate level is suitable when: the business is growing rapidly, has multiple product lines or markets that need synchronization, and requires more frequent identity reviews. This is the level Sinh Vũ often recommends for clients in the expansion phase.
Large level is appropriate when: it is a multi-brand corporation, requiring management of the entire system, demanding high-priority responses, and involving many stakeholders that need coordination. Sinh Vũ refers to this as the large enterprise level, corresponding to about 180 hours per month. The specific number is always through consultation and quotation as the operational rhythm of each enterprise varies.
The first three months of any O1 contract are foundational: reviewing existing brand assets, building the brand portal (a repository for storing and retrieving identity assets), and accurately measuring the actual workload. This phase provides Sinh Vũ and you with data to adjust the fund size starting from the fourth month.
Practical advice: start at a moderate level, measure actual usage over three months, then adjust up or down. Avoid locking in a large number right from the start without data on your actual operational rhythm with the studio.

Look back at the last three months: count the number of actual publications released, the number of times you had to revise or handle urgent matters, and the number of brand identity review sessions. Summarize that into estimated hours and add about 15 to 20 percent for unforeseen tasks. That is the basis for Sinh Vũ to advise on an appropriate hour budget.
Consistently not using up hours is a sign that the hour budget is too large compared to the actual pace, or the internal team has managed to handle more than initially expected. Sinh Vũ recommends reviewing after the first three months to adjust to a suitable level, rather than coming up with tasks to use up hours.
