Build a target account list sales can use.

Start with the unit your team sells to. A legal entity, parent group, operating site and buying team can represent different decisions. A wholesaler serving branches may need site records beneath the parent company. A staffing firm may have separate relationships with several hiring teams at one employer.

Choose that structure before collecting contacts. Otherwise three branches can look like three unrelated companies, or a single group record can hide local buying responsibility. Give each record a stable identifier, retain the parent relationship and connect people to the appropriate account.

Consider a group with one registered office and three plants. If only two plants use supported equipment, the group name alone is insufficient for selection. The account record needs the operating site, relevant requirement and buying relationship. A company contact directory answers who appears to work there; the account list must explain why the specific unit belongs.

Write down the counting unit too. If research starts with legal entities and ends with sites, keep both totals rather than presenting the larger count as market growth. An account-research brief helps resolve the relationships when a directory or shared domain leaves them unclear.

An ideal customer profile describes the companies you can serve well. Convert it into checkable rules: relevant work, delivery geography, operational requirements and exclusions. Separate requirements from preferences. If employee count is used, explain what it indicates and what it cannot confirm.

An industrial supplier targets plants in its delivery area using supported equipment. Relevant maintenance work is required. A dated expansion announcement may increase review priority. A plant outside the service area is excluded; an unknown equipment model goes into research. Unknown and unsuitable need different next steps.

Attach a reason to each decision. “Research: model unconfirmed; check the maintenance specification” gives the next person something to do. A blank suitability score does not. Keep a rule version so the team can reproduce why an account entered a campaign batch.

Avoid loosening the rules merely to reach a desired list size. If too few accounts have evidence, investigate coverage or reconsider the commercial scope openly. Quietly treating missing values as matches creates a larger list by lowering its meaning.

Assemble records from sources suited to the rules: customer systems, company websites, relevant registers and specialist directories. Record the source, access date and what it actually establishes. The UK’s Companies House service supplies registered company information, including addresses and incorporation dates. That does not establish an operating site’s equipment or demand for your offer.

Keep original source values alongside the checked record. A directory may use a trading name; the company site may list operating locations; the CRM may contain a parent account. Decide whether those records refer to the same entity, related sites or different businesses before merging them.

HubSpot’s data-sync matching documentation shows how selected identifiers can change which records match and when duplicates appear. The practical lesson is to test your identifiers on actual examples, rather than assume a shared website or similar name means one buying decision.

Separate coverage from certainty. A directory may omit small operators or a source may be inaccessible. Record the uncovered part of the market. Keep eligible-account counts apart from revenue estimates, which need a period and assumptions about relevant spend. A raw list is neither a market share calculation nor a forecast.

If additional fields would improve a specific decision, use the enrichment evaluation to check matching, freshness and conflicts before applying them widely. More populated cells are useful only when the values are correct enough for the intended task.

If the usual database misses suitable businesses, change the entry point. Investigate the locations where relevant work takes place, specialist industry listings or public project information. Record what each source covers and misses. Two lists drawing on the same source do not necessarily improve coverage.

Example. A maintenance provider finds a suitable production site under a trading name. Its location page names an operator; a group website lists several sites. Keep the site, operator and group as separate related records until the buying relationship is confirmed. The useful next step may be a question to the operating organisation, rather than a message to the first executive found in a database.

For a difficult account, name the unresolved question and decide how much effort it warrants. The next source or contact route should have a reasonable chance of changing the decision. Keep “not found”, “not yet confirmed” and “not suitable” distinct. Some questions can be resolved through research; others need a conversation. Agree the next step and who takes it.

Match the market map against current customers, former customers, open opportunities and recorded exclusions. Preserve the relationship owner and the relevant dates. An unfamiliar branch may belong to a known group, or an apparently new account may already have a proposal under discussion.

Keep new prospects and existing-customer opportunities distinct. A customer may buy from one branch while another suitable branch remains unserved. Ask the account owner to review that gap alongside the relationship history before choosing an approach.

Check why the gap exists. A territory agreement, unsupported requirement, unresolved service issue or existing conversation can change the next action. A missing product purchase is a question to investigate, not evidence of demand. The customer whitespace guide develops the order-history and false-gap checks.

Exclusions should travel with the working list. A suppression or account-owner instruction cannot protect the relationship if it exists only in a spreadsheet that the campaign operator never sees. Name which record is authoritative and when the list must be checked again before use.

1. Choose a mixed sample. Include clear fits, exclusions, uncertain prospects and existing customers. Ask two colleagues to apply the written rules independently. Give them the same source set and ask them to record the buying unit as well as include, exclude or research.

2. Compare the disagreements. Check whether the rule is ambiguous, the evidence is missing or the account structure is wrong. If one reviewer counted a parent and another counted two sites, fix the unit before discussing list size. Keep the reason for the corrected decision.

3. Hand over the list. Give every included account an owner, reason for inclusion, evidence and next review date. Ask the recipient to choose a next action without repeating the whole search. Note where they need another source, relationship check or explanation of the rule.

Use those findings to refine the next batch. A technically deduplicated file can still fail if the owner cannot tell which site to approach or whether another colleague is already involved. Review the usefulness of the record, not only its formatting.

Capacity comes after fit. If one person can only investigate a small set, do not delete the rest of the suitable market to make the workload look complete. The territory coverage guide keeps serviceability, named ownership and available capacity visible as separate questions.

Keep ownership, exclusions, duplicates and customer relationships up to date. Record why an account enters or leaves a working batch. Carry forward promises to wait and questions colleagues are already resolving when you create the next list version.

Fit determines which companies belong. Buying signals may inform when to review a suitable account, but an observed change does not automatically establish need or contact permission. A campaign can also begin with a defined audience and proposition without a new event at every account.

We can deliver the research and a usable account list as an independent assignment through Plan. For a complete campaign, Build includes planning, setup, operation and optimisation within the agreed scope. A useful list or existing research is a starting point; a paid Plan is not required when the campaign can already be scoped. See our research approach for accounts that need further investigation.
