Everything in one place

Every tool you need to build, check, and submit a defensible HMRC VAT reclaim — without the spreadsheet headache.

Project VAT Analysis

Answer interactive questions about your project to understand which VAT rules apply and where savings may be available

VAT Opportunity Report

Generate a detailed project-specific report explaining work package VAT treatment, potential savings and HMRC references for contractors and advisers.

Invoice analysis

Upload PDFs, photos, Word docs, or Excel files. VATBuild reads every document, extracts each line item, and checks it against HMRC Notice 708 — automatically.

Supplier correction emails

When a contractor charges the wrong VAT rate, VATBuild flags it and drafts a professional correction request email pre-filled with the invoice details and the correct rate.

Live VAT registration check

Before paying a VAT invoice, instantly verify your supplier is genuinely registered with HMRC. A single click checks the live HMRC database — so you never reclaim VAT a supplier wasn't entitled to charge.

Claim Readiness score

A live score out of 100 tracks invoice quality, document completeness, photo evidence, and HMRC deadline — so you know exactly what to fix before submitting.

VAT Actions

A built-in checklist of everything that needs managing throughout your project — completion certificates, supplier VAT records, claim deadlines, and more. Nothing falls through the cracks before you submit.

HMRC form pre-fill

VAT431NB and VAT431C form fields populated from your project data. Copy them straight to the HMRC form — no re-keying, no errors.

Compliance audit

Before you submit, VATBuild reviews every line item in your claim for overclaiming risks — with specific HMRC rule references for anything flagged.

Live spend tracking

Track total spend by supplier and category in real time as invoices are uploaded. See exactly where the budget is going and what the VAT position looks like at every stage of the project.

Works on any device

Fully responsive — photograph and upload an invoice onsite from your phone, then review and generate reports from your desktop. No separate apps needed.
