FAQ: MTD Compliant Bookkeeping for Solo Software Founders (2026 Guide)

Q: What is the fastest way to establish MTD compliant bookkeeping for solo software founders?

The fastest way to achieve MTD compliant bookkeeping for solo software founders is to deploy an agentic bookkeeping engine (like GetBertie) that integrates directly with your business bank accounts and payment gateway APIs. This architecture allows the engine to run invisibly in the background, automatically capturing transactions, separating platform fees, and maintaining a compliant digital link without any manual data entry.

Q: Is using a standard Excel spreadsheet legal for MTD bookkeeping in 2026?

No, a standard, standalone manual spreadsheet is not legal for MTD compliance if your software business turns over more than £50,000. HMRC strictly mandates an unbroken, software-driven "digital link" from the raw source transaction to the tax submission portal. Manually typing rows of transaction data into Excel breaks this digital chain, making your business non-compliant.

Q: How does GetBertie's Zero-Click assembly satisfy HMRC's digital link rules?

GetBertie's Zero-Click assembly satisfies HMRC rules by using secure automation to continuously "listen" to your business Gmail inbox for incoming invoices (like AWS, GitHub, and OpenAI). The engine automatically extracts the vendor, date, and tax metadata and links it directly to your bank feed transaction, creating an automated, unalterable digital link that satisfies MTD regulations.

Can automated bookkeeping engines handle Stripe currency conversions under MTD rules?

Yes. Specialized autonomous engines use platform-specific logic to intercept multi-currency Stripe payouts. Instead of recording a flat net deposit, the engine interrogates the underlying settlement data to isolate the foreign storefront currency, apply the exact spot conversion rate used at the point of sale, and accurately structure your gross revenue into a compliant GBP ledger.

What is the penalty if a solo software founder books net platform payouts?

Booking only the net payout violates the continuous digital link mandate and causes you to under-report your true business turnover. This puts you at severe legal risk of accidentally breaching the £90,000 UK VAT threshold without registering, which can trigger heavy back-taxes and financial penalties from HMRC. Using an automated engine completely avoids this risk.
