What you get in the accounting firm package

Secure client portal (invoice upload, audit log, 2FA, EU hosting)

No more invoices in email (GDPR risk). Clients log in with 2FA and upload PDF/JPG/PNG through an encrypted form. Every access lands in an audit log (timestamp + user + IP). Vercel EU Frankfurt hosting, processor DPA in place, TLS 1.3, at-rest encryption on S3-compatible storage.

Integrations with Xero / QuickBooks / FreeAgent / Sage / KashFlow

REST API connectors to the UK's mainstream accounting systems. Clients see in the portal: current VAT obligations, list of issued invoices, MTD submissions awaiting approval, outstanding balances. Auto-sync every 15 minutes or on demand. On your side: zero manual exports — clients self-serve.

Online pricing calculator (bookkeeping, payroll, VAT returns, year-end)

Clients pick their entity type (sole trader / Ltd / LLP), document volume, and add-ons (payroll, MTD VAT, year-end accounts, P11D). They get an instant quote — your inbox and phone stop being clogged with "how much do you charge?". Every calculation is captured in the CRM for follow-up.

Tax blog with AAT/ACCA-credentialed authors (E-E-A-T)

Article publishing system with authors registered with a professional body (AAT/ACCA/ICAEW membership number, biography). Each article gets AccountingService + Article JSON-LD — Google trusts authors with formal credentials (a critical E-E-A-T signal for YMYL financial content).

How we work with accounting firms

  1. Compliance audit (GDPR + ICO + professional body confidentiality rules)

    We jointly review current processes: how clients deliver invoices (email/Dropbox = high risk), where data is hosted (UK/EU/US?), who has access. GDPR + ICO guidance + AAT/ACCA/ICAEW confidentiality rules = full professional-secrecy requirement that exceeds vanilla GDPR.

  2. Information architecture (services, pricing, team, portal, blog)

    Pages per service type (bookkeeping / payroll / VAT returns / year-end accounts / tax planning / MTD), pricing with an online calculator, team page with professional-body credentials and specialisations, client portal as a separate authenticated path, blog as an expert content marketing surface.

  3. Implementation on Next.js + AccountingService schema + Vercel EU

    Stack: Next.js 16 / Tailwind v4 / Vercel Frankfurt EU. AccountingService JSON-LD for the firm, ProfessionalService for the team (with credentials visible). PageSpeed >95, TLS 1.3, HSTS preload, DPA with every sub-processor (Vercel, SMTP, accounting system).

  4. Monthly support (VAT rates, pricing, tax blog)

    Monthly maintenance: current VAT rates, filing deadlines, MTD thresholds, blog publishing, GSC position monitoring, minor frontend tweaks. Your clients always see up-to-date information without you having to lift a finger.

Common questions from accounting firms

Yes. AAT/ACCA/ICAEW confidentiality codes plus the Anti-Money Laundering rules require: client data accessible only to licensed staff or those with confidentiality clauses, physical/logical data protection (TLS, audit log), data destruction at the end of the engagement. We deliver: EU hosting (Frankfurt), TLS 1.3, audit log for every access, RBAC (role-based access), DPA with sub-processors, GDPR privacy notices, automated account purging after termination.
