Tasks that must be treated as separate projects, not included in the monthly hour budget.

Monthly operational retainer hours are not an endless pit. They are designed to support consistent work: running enough, running correctly, without interruption. When you push a large task into that retainer without separating it out, the entire regular operational schedule will be affected. And usually, no one realizes this until it is too late.

Two types of work with different natures.

The simplest way to differentiate is to ask: does this have a clear starting and ending point, or does it just repeat regularly each month?

• Tasks within operational hours: periodic sales publications, social media content, brand consistency checks, minor edits, cyclical document updates. These tasks have no end point as they need to be done again every month.
• Tasks that must be separated into their own projects: creating a new brand identity or rebranding, producing large-scale films and photos, organizing events, large campaigns with multiple components. These tasks have a clear start and end, and a significant volume that requires a scope, checkpoints, and independent pricing.

The exclusion list is as important as the inclusion list. Disputes often arise over points that are not clearly stated, rather than over things that everyone understands as major or minor.

Gray area: tasks that are unclear about ownership

Not always clear boundaries from the start. Your request for "updating the sales document set" could be a minor edit within the time budget, or it could require a complete redesign.

For gray areas, Sinh Vũ's approach is to ask for clarification and estimate effort before accepting, rather than forcing it into one of two boxes to finish. Avoid both leniency and rigidity, as both can cause harm later.

The change order mechanism: when out of scope arises.

When you request work beyond what was agreed upon in the package, the proper response is not to refuse, nor to quietly do it for free. It is to create a change order (a document detailing the scope, costs, and deadlines for the additional work) for both parties to confirm before proceeding.

When clients request work outside the scope, the standard approach is to create a change order to agree on costs and timelines, rather than silently doing it for free.

This process protects both sides: you know the costs in advance and are not caught off guard, while Sinh Vũ is not drained of resources without a plan. Without a change order, any additional costs will lead to conflicts later because no one has recorded what was agreed upon.

Common errors when there are no clear boundaries

• Customers see retainers as unlimited work: misunderstanding that a monthly package includes all requests regardless of scale. This is the most common and costly misunderstanding if not clarified from the start.
• Partners who take on large projects for the sake of relationships: to maintain relationships, they accept large projects without additional charges, leading to delays in all regular work. The client gains nothing, and the partner becomes exhausted.
• No change request process: Issues arise, and no one knows how to handle them, resulting in inevitable disputes.

The viewpoint of Sinh Vũ

Sinh Vũ's operations package has two flexible mechanisms: transferring up to 20% of unused hours to the next period, and allowing up to 130% of hours during peak seasons. Both mechanisms apply only to regular work, not for large production loads.

The reason is not due to rigidity. The reason is that when Sinh Vũ takes on a large campaign or event setup within operational hours without separating them, your regular tasks will be compressed or delayed. You gain nothing; you only lose the stability that the monthly package is providing.

For major projects, Sinh Vũ separates them into distinct projects with clear scopes, specific checkpoints, and independent pricing. Two tasks run in parallel but do not interfere with each other. This is the only way to ensure both regular operations and large-scale production are executed with the right quality.
