How to assess capacity and continuity at a small supplier

A small supplier can offer close attention and specialist knowledge, but buyers should understand how work continues when demand rises or a key person is absent. Ask for the actual delivery plan, not a vague assurance that the team is flexible. The goal is a service that fits your needs and a realistic response to disruption.

Ask who will do the work

Request the proposed roles, availability and expected share of attention. How many projects will the same people support? You do not need access to private staffing details, but you should know whether critical tasks depend on one person and whether a backup has been identified. Ask who can approve decisions if the usual contact is away.

Compare this with the proposed schedule. A supplier can be highly skilled and still lack capacity to meet a specific deadline.

Examine the continuity process

Ask where project documents, decisions and credentials are stored. Would another authorised team member be able to find the current brief, recent changes and next task? What happens during planned leave, illness or a sudden workload increase? A useful answer describes an actual handover routine and a customer communication plan.

If specialist work is subcontracted, clarify who reviews it and who remains accountable. The subcontracting questions provide a practical checklist.

Test with two scenarios

Present a routine scenario: your main contact is away when you need a small change. Then present a serious one: an important service fails during a busy period. Ask who responds, what information that person can access and when you would receive an update. Scenarios reveal the difference between a named backup and a working process.

Match requirements to the risk

For a short, low-impact assignment, a simple backup contact may be enough. For work that affects customers every day, ask for clearer escalation, documentation and response commitments. A larger supplier is not automatically safer; assess its actual account team and continuity arrangements against the same criteria.

Record commitments in the agreement

If continuity is material, include named roles or role types, support hours, escalation and handover obligations in the written terms. Review them as the service grows. A plan that was sufficient for a small project may need updating when more sites or users depend on it.

Ask for an evidence-based backup plan

A named deputy is useful only if that person can find the current work and has authority to act. Ask the supplier to show how project notes, access and unresolved risks are shared internally. For a long engagement, schedule an occasional review with the backup contact so they are not a stranger during an incident. If the business is a sole trader, discuss a practical transfer arrangement and the records your organisation will retain. Match this level of preparation to the cost of an interruption.

Frequently asked questions

Is a one-person supplier too risky?

Not always. Consider the importance of the service and whether the supplier has a workable backup or transition arrangement. Ask what records your organisation would retain if the supplier became unavailable.

Should we ask about other clients?

You can ask how capacity is managed without demanding confidential client information. Focus on availability and contingency for your work.

What if the proposed lead changes?

Ask how the replacement will be introduced, briefed and assessed against the skills required for your project. Confirm how the new lead receives the brief and outstanding decisions before taking responsibility.
