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, GDPR-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.
