Perfex CRM Developer for UK Businesses
UK agencies, IT providers and service firms choose Perfex CRM to avoid per-user SaaS fees. To fit UK operations, it usually needs a few things it doesn't have out of the box: VAT invoices that satisfy HMRC, a clean route into Making Tax Digital, Direct Debit for recurring work, and UK GDPR-friendly data handling.
We build Perfex CRM customizations and modules for UK businesses. Our afternoon overlaps with your morning, so feedback you send before lunch is typically turned around the same day.
Perfex CRM Challenges for UK Businesses
HMRC-compliant VAT invoices
A full UK VAT invoice needs your VAT registration number, a tax point, the VAT rate and amount per line, and correct treatment of reduced, zero-rated and exempt items, plus reverse-charge wording where it applies, such as for construction services. We adjust Perfex taxes and PDF templates so every invoice and credit note meets HMRC requirements.
Making Tax Digital
VAT-registered businesses must keep digital records and file VAT returns through MTD-compatible software. MTD for Income Tax applies to sole traders and landlords with qualifying income over £50,000 from April 2026. Perfex is not MTD-recognized software itself, so we sync invoices, payments and expenses into Xero, QuickBooks, FreeAgent or Sage, which then file with HMRC.
Direct Debit for retainers and subscriptions
UK clients expect to pay recurring fees by Direct Debit. We integrate GoCardless with Perfex recurring invoices so mandates are collected once and payments are taken and reconciled automatically.
UK GDPR and data protection
Perfex includes basic GDPR tools. We extend them with retention rules, consent logging on web-to-lead forms, subject access request exports and anonymization, and can host your installation on UK or EU servers.
Integrations UK Clients Ask For
Every integration is built as a standalone Perfex module using official hooks, so it survives Perfex updates. More about our API integration work.

Perfex CRM in UK: FAQs
Is Perfex CRM compatible with Making Tax Digital?
Perfex is not MTD-recognized software on its own. The common approach, which we implement, is to sync Perfex invoices and payments to Xero, QuickBooks, FreeAgent or Sage, which submit VAT returns to HMRC.
Can Perfex CRM take Direct Debit payments?
Yes, with a GoCardless integration. We connect GoCardless to Perfex so mandates are set up once and recurring invoices are collected and marked paid automatically.
Can you make Perfex invoices meet HMRC VAT rules?
Yes. We configure VAT rates and customize the invoice and credit-note templates to include all the details HMRC requires, including reverse-charge wording where needed.
Is Perfex CRM UK GDPR compliant?
Perfex includes GDPR features such as consent and data export. Compliance depends on how you configure and host it. We add retention rules, consent logging and SAR exports, and can host on UK or EU servers.
Do you invoice in GBP?
Yes. We quote and invoice UK clients in GBP, and we work during your morning hours over Teams, Google Meet or Slack.
