Looking for Developers to Build an HMRC-Compliant Accounting Platform

I’m looking for a developer or team to build an online accounting and tax platform similar to Capium/Sage/Apari Software/BaseTax Limited /Blueprint Labs/ BTCSoftware by Bright/CalCal Ltd fully compliant with HMRC requirements (Making Tax Digital).

Platform Goals:

• Enable businesses and accountants to submit VAT, Income Tax, and payroll data digitally.
• Support secure digital record-keeping-with audit trails.
• Direct API submission to HMRC (MTD-compliant).
• Role-based accounts (admin, accountant, client).
• Cloud-based document management and dashboards.
• Automated calculations for VAT, payroll, and tax returns.
• Scalable, secure, -compliant web application (mobile-friendly optional).

Technical Requirements:

• Integration with HMRC APIs(sandbox testing first).
• OAuth 2.0 authentication for users.
• Complete audit logs and secure data handling.
• Optional: notifications, reporting, and analytics.

What I’m Looking For:

• Experience with tax/accounting software or HMRC API integration
• Ability to deliver an MVP first, then scale.
• Portfolio of similar projects.
• Suggested tech stack, timeline, and cost estimate.

Think Capium + HMRC MTD compliance but modern, user-friendly, and scalable.

Budget: GBP 363 (Fixed Price)
