The e-invoicing market is crowded, and the wrong choice is expensive to reverse. Once your invoice numbering sequences, partner records, and tax authority registrations are tied to a platform, switching costs are high. Choosing a provider is therefore a decision that deserves structured analysis not a rushed sign-up because a deadline is approaching. This guide gives you ten concrete questions to put to any provider before you commit, plus a framework for comparing answers and an honest look at how Docnova measures up on each dimension.
Why Your Choice Matters
E-invoicing is not a commodity. Providers vary significantly across three dimensions that compound over time: regulatory coverage, network reach, and operational reliability.
Regulatory coverage determines whether the platform can legally generate and receive invoices in every country you operate in. Germany requires XRechnung or ZUGFeRD formats. Poland mandates KSeF. Belgium, Malaysia, and a growing list of countries each have their own structured formats and tax authority portals. A provider that covers only one country forces you to operate multiple tools as you expand.
Network reach determines whether your counterparties can receive what you send. The Peppol network is the dominant interoperability layer in Europe, connecting buyers and sellers across Access Points. A provider that is not a certified Peppol Access Point cannot deliver invoices to the millions of businesses and public bodies that require Peppol delivery.
Operational reliability covers uptime, support responsiveness, and data ownership. Tax authority submissions have hard deadlines. A platform outage at month-end is not an acceptable excuse with a VAT inspector.
Getting these three dimensions wrong in your provider selection can mean compliance failures, lost invoices, and a painful migration later.
Questions to Ask
1. Which countries and invoice formats do you support? Ask for a specific list. Vague claims like “EU-ready” are not sufficient. You need to know whether the provider handles the exact formats your tax authorities require today and whether their roadmap covers countries you plan to enter.
2. Are you a certified Peppol Access Point? Peppol connectivity is essential for B2B and B2G transactions across Europe and beyond. Confirm the provider is a certified AP, not merely integrated with one.
3. How do you handle country-specific mandatory fields? Every country has unique required data elements. Ask how the platform enforces these. Does it validate at the point of entry, or do you find out about errors after a rejected submission?
4. What are your invoice volume limits and pricing tiers? Many providers charge per invoice or per user. Understand the pricing at your current volume and what it looks like if you double. Look for transparent tier definitions.
5. How do you manage incoming invoices from suppliers not on Peppol? Not all suppliers are digitally mature. Ask whether you can receive invoices via upload (XML, PDF, image) and whether OCR or extraction is included.
6. What does your subscription plan include? Specifically: is Peppol registration included, or priced separately? Are reporting features in the base plan or an add-on?
7. How are partner/counterparty records managed? Ask whether the platform maintains a partner directory with VAT IDs, Peppol IDs, and addresses. Re-entering buyer details on every invoice is a red flag for operational maturity.
8. What reporting and financial overview features are available? You need more than a list of invoices. Ask whether the platform provides income/expense summaries, VAT reports, AR/AP aging, and cash flow views.
9. What integrations do you support? ERP, accounting software, and banking integrations reduce double-entry. Ask about API availability and existing connectors.
10. What is your data portability and exit policy? If you switch providers in two years, can you export all your invoice data in a machine-readable format? Who owns the data?
Comparison Framework
Use this table to score providers side by side. Rate each criterion 1–3 (1 = not supported, 2 = partial, 3 = fully supported).
| Criterion | Weight | Provider A | Provider B | Docnova |
|---|---|---|---|---|
| Country/format coverage | High | — | — | — |
| Peppol Access Point | High | — | — | — |
| Mandatory field validation | High | — | — | — |
| Volume pricing transparency | Medium | — | — | — |
| Incoming invoice handling | Medium | — | — | — |
| Partner directory | Medium | — | — | — |
| Financial reporting | Medium | — | — | — |
| ERP/API integration | Low | — | — | — |
| Data portability | Low | — | — | — |
Multiply each score by weight and sum to produce a weighted total. Any provider scoring below 2 on a High-weight criterion should be disqualified regardless of total score these are non-negotiable capabilities.
