Hermes - AP Automation

The number one challenge in AP Invoice processing that we heard from CFOs was a high volume of non-standard invoices in multiple formats received from hundreds of vendors mostly via email round the clock. Other concerns and challenges the Accounts Payable team faced were the need to verify and process these invoices manually, checking for multiple validations for accuracy and validity of the invoice. Apart from the huge manual data entry effort of manually keying the invoice into the AP software, there was also a lot of manual effort to validate the invoice against PO, Contract, Vendor Master, and Tax calculations. Hermes - AP Automation was built keeping this in mind.

Smart Date Auto-Population • Current Date Insertion: Automatically fills in the current billing date upon generating a new invoice. • Accuracy Guarantee: Reduces repetitive typing steps and eliminates backdating mistakes across client statements. 4. Seamless Integration with 400+ Free Excel Templates • Massive Template Library: Integrates directly with Uniform Software’s free online collection of over 400 industry-tailored Excel invoice, estimate, quote, and receipt templates. • Industry-Specific Layouts: Supports formats designed for general sales, professional service billing, trade contracting, commercial sales, VAT/GST compliance, and international currencies. • Custom Template Support: Flexible enough to work with existing custom Excel billing sheets created by the user. 5.

Cross-Platform Office 365 Architecture • Browser & Desktop Support: Operates smoothly across Excel for the Web, Windows desktop Excel, and Mac desktop Excel. • Cloud & Remote Friendly: Ideal for distributed teams or remote contractors working within shared Microsoft 365 web environments. Core Business Benefits • Eliminate Software Subscriptions: Provides essential billing automation at zero cost, removing the need for paid cloud accounting subscriptions for micro-businesses. • Zero Learning Curve: Operates directly within the familiar Microsoft Excel interface, eliminating staff training or software onboarding. • 100% Design Control: Avoid standardized, rigid invoice layouts imposed by traditional accounting SaaS platforms. • Reduced Administrative Overhead: Automates repetitive tasks like numbering, date population, and form wiping to save hours of administrative work each month. • Seamless Scalability: Templates and workflows created in Invoice Manager Lite offer forward compatibility with Uniform Software’s advanced desktop database applications (Invoice Manager for Excel) if business growth requires customer databases, product catalogs, and payment tracking in the future.

InvoiceXML

InvoiceXML is a REST API that lets developers and finance teams generate, validate, convert, render and extract compliant electronic invoices without building or maintaining e-invoicing logic themselves. It is compliance infrastructure that sits inside your existing architecture: send invoice data, receive a compliant document back. All major European e-invoice formats in one API. InvoiceXML supports ZUGFeRD, XRechnung, Factur-X, UBL, CII and Peppol BIS Billing 3.0, so a single integration covers the German e-invoicing mandate, the French e-invoicing reform, and Peppol-based invoicing across Europe. Convert between formats, for example CII to UBL or UBL to Factur-X, without writing mapping code. Keep your invoice design. For hybrid formats such as ZUGFeRD and Factur-X, InvoiceXML embeds the structured XML into your existing PDF and produces a compliant PDF/A-3 document. The invoice your customers see looks exactly as it does today. Every invoice validated before it leaves. Each document is checked against the official Schematron artefacts and the EN 16931 standard before delivery, so an invalid invoice never reaches you or your customers. Validation errors come back with the specific rule, business term and field affected, not a vague pass or fail. Standalone validation and PDF validation reports are also available. Compliance as a service. E-invoicing rule sets change several times a year on binding deadlines. InvoiceXML updates them at the effective date, with no code change or deployment on your side. The build is finite; the maintenance never is, and InvoiceXML takes it off your roadmap. Zero data retention by design. Invoices are processed in memory, never written to disk, never logged and never backed up. Processing takes place exclusively on servers in Frankfurt, Germany, so data never leaves the EU. GDPR compliant, with a Data Processing Agreement available. Built for automation. Integrate directly via REST with code examples in C#, Java, JavaScript and more, or connect through Zapier, Integrately, Power Automate and other automation platforms. AI-powered data extraction from plain PDF invoices returns a confidence score per field, so your pipeline can auto-accept clean documents and flag the rest. Who it is for. ERP and SaaS vendors adding e-invoicing to their product, fintechs and invoice-financing platforms processing inbound invoices, accounting firms serving many clients, and any business with an existing billing system that needs to meet the German B2B mandate, the French mandate, or the EU-wide ViDA requirements by 2030 without replacing the system that already works.
