How accountants can assess lead generation software

What to take away

Compliance is a buying criterion, not a footnote. When assessing lead generation software, professional body ethics and UK data law both shape how you contact prospects.
Public company data beats bought consumer lists. Filing dates and director changes show where advice is needed.
Buy for the tax calendar. Demand builds before the 31 January filing deadline and the 31 July payment on account.
Test integration and exit before price. Ask where contacts, notes and consent records live if you switch suppliers.
Insist on a recorded lawful basis. If the tool cannot show why a contact sits in the system, a complaint is hard to answer.

Where accountancy leads actually come from

Most practices do not win work from a bought list of names. Clients arrive through referrals, through existing contacts whose circumstances change, and through search queries tied to deadlines.

Where accountancy leads come from

Bought list

Source: Purchased names
Example: Cold contacts
Example: Generic outreach
Example: Volume play
Check first: Unclear origin

Trigger signals

Source: Public records
Example: VAT registration
Example: Director changes
Example: Audit threshold
Check first: Companies House

A sole trader registering for VAT, a landlord with rental income, or a company nearing its first audit threshold all create work. Software for accountants should surface those triggers rather than add volume.

Public records carry the strongest signals. Companies House filings show incorporation, accounts status and director changes, and you can search the register yourself through the Companies House service to test a data source before paying.

Companies House can show incorporation, accounts status and director changes, but it will not prove buying intent. When reviewing a vendor's prospecting software data sources, ask for the named source, record-level provenance, when records were last refreshed and how errors are corrected. Test sample company records against the Companies House service before paying.

Five checks when assessing providers

Examples to put through the same checks include Apollo, Cognism, Lusha and LinkedIn Sales Navigator. This is a starting shortlist, not a ranking or endorsement: verify each product's data, channel coverage and fit for your practice before choosing.

Lawful basis. Each contact should carry a record of where the data came from and why you may contact that person. UK GDPR Article 6 requires a lawful basis for processing personal data. Legitimate interests may be relevant to B2B prospecting, but it is not automatic: document the purpose, necessity and balance against the person's interests and rights. Consent is another possible basis.
Sector fit. Filter by company size, SIC code and incorporation date rather than job title alone. Your buyers are businesses, not consumers.
Channel rules. Check the rules for each channel, including PECR for electronic marketing, and ask how the provider handles objections and suppression lists.
Integration. Leads that never reach your practice management or CRM system go cold. Ask how records sync, which fields survive the transfer and whether consent and suppression records are included.
Export and deletion. Confirm you can take your data out in a usable format, and that the supplier deletes it when you leave.

The rules that narrow the shortlist

Two sets of obligations shape the shortlist: your professional body's conduct requirements and data protection and marketing law. Depending on your firm's memberships, check the relevant current guidance from ICAEW, ACCA, AAT, ICAS or CIOT. Marketing should be honest and not misleading, and must protect client confidentiality.

PECR (the Privacy and Electronic Communications Regulations 2003) governs electronic marketing, alongside data protection law. For email and text marketing to individual subscribers, consent is generally required unless the soft opt-in applies. That exception is limited: the contact details must have been obtained directly during a sale or sale negotiations, the marketing must be for your own similar products or services, and the person must have had a chance to opt out when their details were collected and in every message. Every message needs a clear opt-out. The ICO's direct marketing guidance explains how the rules work in practice, including what they mean for bought-in lists.

Confidentiality is the sharper edge here. If a prospect is already a client, or connected to one, your marketing list must not reveal that relationship. Test how the software handles suppressed and related contacts before you buy.

Fit the tool to the tax year

Window	Client concern	What to look for
April to June	New tax year, first VAT returns	Simple segmentation and task reminders
July	31 July payment on account	Date-triggered campaign scheduling
September to December	Year-end planning and capital allowances	Filters on company year-end dates
January	31 January filing and payment deadline	Website enquiry capture and fast follow-up
February to March	Late filing and post-deadline reviews	Reporting on which campaigns produced clients

Seasonality decides what you need. A tool built for one-off list pulls will not carry a repeatable January campaign.

Practices that start prospecting in November, ahead of the HMRC self assessment rush, get more from a licence than those buying in February, when attention has moved to fee collection.

Check the pricing model before you commit

Vendors price in different ways: per seat, per contact credit, or per email sent. Per-seat licences suit steady outreach. Credit-based pricing suits a firm that campaigns hard around deadlines and stays quiet in between.

Ask for a twelve-month quote that itemises data top-ups, onboarding and support; the pricing models alone will not show your total cost. If you already use systems such as Xero, Sage, IRIS or AccountancyManager, ask the supplier which ones it supports and whether the connection is native or uses middleware. Test a sample sync and export before committing. The prospecting software CRM integration comparison can provide further context, but verify compatibility with your own setup.

Common questions

Can accountants use purchased contact lists?

Treat bought consumer lists with caution. For email or text marketing to individual subscribers, a bought list does not by itself establish consent or qualify for the soft opt-in. Ask the supplier for the source and evidence of permissions, then check that the contact's status and any objections are recorded before use.

Does cold email work for accountancy practices?

It works when the trigger is specific. Emailing a director whose company has just missed its filing deadline reads very differently from a generic blast.

Do I need consent to email a limited company?

Corporate subscribers sit outside the individual consent rules for email, but sole traders and some partnerships do not. Check the legal status behind each address, not just the domain.

Who owns the data if I leave the provider?

Your contract decides that. Export formats, exit rights and deletion timelines belong in due diligence, not in a support ticket after you cancel.
