Our Business Central extensions: what we are building for AppSource

Amplio is building a set of Business Central extensions for Microsoft AppSource. Each one solves a problem we kept meeting on client projects, built once so that any Business Central customer can use it. This post sets out where they stand and what they do.

Key PointThese extensions are in development and not yet on AppSource. Submission is planned across Q4 2026.

Where the extensions stand

As our apps page says, the extensions are in active development and are scheduled for Microsoft AppSource submission across Q4 2026. They are not on AppSource yet.

Before an app is listed, it has to pass Microsoft's checks. The technical validation checklist sets out what an extension must meet. Until launch, you can register for early access and evaluate an app in a sandbox.

UK compliance and tax

• UK Group VAT MTD Bridge. Brings VAT entries together across Business Central companies that share one HMRC VAT registration. Our Group VAT article explains the problem it solves.
• Companies House Integration. Fills customer and vendor details from Companies House data and flags dormant or dissolved companies.
• R&D Tax Credit and Patent Box Tracking. Tags ledger entries against qualifying categories as they are posted, ready for the adviser at year-end. HMRC explains R&D relief.

Pro TipIf one of these matches a problem you have now, register for early access and test it in a sandbox before launch.

Finance and accounting

• Bank Statement Importer and Smart Reconciliation. Imports UK bank statements and suggests matches based on past reconciliations.
• Mass Journal Paste and Excel Power-Edit. Pastes rows from Excel straight into Business Central journals, with checks as you go.
• Multi-Entity Allocation and Recharge Journal. Allocates and recharges costs across Business Central companies.
• Smart Recurring Contracts and Renewals Manager. Manages contracts and renewals on top of Business Central subscription billing.

Customer-facing and workforce

• Customer Self-Service Portal. Lets customers see statements, download invoices and pay online.
• Branded Document Delivery and Open Tracking. Sends branded email documents and records when they are opened.
• HR-Lite for Business Central. Handles UK leave and sickness, with absence flowing into project costs.

Watch OutPlan around what is live, not what is planned. Until an app passes Microsoft validation, treat its launch date as a target.

Why we publish as extensions, not bespoke code

Building to AppSource standards means an extension is built for Business Central online from the start. It also means the same tested app reaches every customer, rather than a one-off build for each.

When a problem is specific to one business, we still build custom extensions. Our Business Central extensions page covers that service.
