For most companies, the answer depends on how many countries you invoice in and whether you have developers. Software companies and platforms that want to add e-invoicing to their own product usually pick an API: Storecove for Peppol and DBNAlliance access from €3,300 a year, or Invopop, which has a free developer tier and paid usage from €40 a month. Multinationals with SAP or Oracle and invoices in many countries choose a global network such as ONESOURCE Pagero, Sovos or Comarch, which handle both Peppol and the national clearance systems in Poland, Italy and Latin America. Fonoa suits digital platforms that need tax determination, e-invoicing and reporting from one API. France's mandate went live on September 1, 2026, Belgium's on January 1, 2026, and Poland's KSeF in February and April 2026.
Storecove, founded in 2014 in Hilversum, Netherlands, is a Peppol and DBNAlliance access point with a single JSON API that also connects to tax authority channels such as Italy's SDI and Spain's FACeB2B, across more than 30 countries. Accounting software vendors and ERP partners use it to give all their customers e-invoicing without joining each network themselves. Pricing is published: Starter annual maintenance is €3,300 for cloud accounting and integrator plans and €3,960 for Enterprise, plus per-document charges. That entry price is too high for a single small business, but cheap for a software vendor serving thousands.
Pricing: Storecove publishes Cloud Accounting, Enterprise and Integrator tiers. Starter annual maintenance is €3,300 for Cloud Accounting and Integrators, and €3,960 for Enterprise, before per-document charges. Add-ons include archiving at €3,000 per 100,000 documents and invoice response at €1,200 per 100,000.
A single REST API abstracts multiple networks, formats and country requirements.
Published pricing includes meaningful volume and entity bands rather than seat-based billing.
The sandbox supports testing across Peppol and selected tax-authority environments.
The lowest published annual fee is substantial before usage charges, making it unsuitable for very small volumes.
Most buyers need developer resources and an existing ERP or accounting system.
Reporting, error detail and self-service invoice creation are less extensive than a full finance suite.
Global e-invoicing and business-document network for enterprises managing tax compliance across countries and ERP systems.
Pagero, founded in Gothenburg in 2000 and acquired by Thomson Reuters in 2024, runs one of the largest e-invoicing networks, with about 90,000 customers, more than 14 million connected businesses and coverage in more than 80 countries. It handles Peppol and the national clearance and reporting systems, and is being folded into ONESOURCE, so indirect tax determination and e-invoicing can come from one vendor. A free tier allows up to 36 documents a year, which is enough for small suppliers that only need to send invoices to a large customer on the network. Paid deployments are quoted.
Pricing: Pagero does not publish standard paid enterprise pricing. ONESOURCE Pagero Free allows up to 36 exchanged documents per year before fees may apply, with some document types restricted by local compliance requirements. Paid deployments are quote-based and typically depend on volume, countries, ERP connectivity, onboarding and optional capture, archiving or payment services.
Broad country and network coverage reduces the need to contract with separate local access points.
Open connectivity supports major ERP platforms, APIs, SFTP, AS2, cXML and manual web workflows.
AP, AR, supplier onboarding, format conversion and compliance functions are available within one network.
Paid pricing is not public, making enterprise cost difficult to compare before a sales process.
Global deployments can require substantial ERP mapping, partner onboarding and country-specific configuration.
The brand transition to ONESOURCE Pagero can complicate comparisons with legacy Pagero documentation.
Sovos, founded in 1979, serves more than 100,000 customers, including half the Fortune 500, and covers almost 200 countries. Its strength is clearance e-invoicing in demanding jurisdictions, especially Latin America and Southern and Eastern Europe, combined with VAT returns, SAF-T and periodic reporting from the same data. It has more than 75 embedded ERP, AP and AR integrations. G2 lists 92 reviews averaging 4.2, and some reviewers describe interfaces and troubleshooting as complex. Pricing is quoted.
Pricing: Sovos does not publish a standard starting price or public tier table for its core platform. Pricing varies with modules, jurisdictions, entities, transaction volume, integrations, and services. AWS Marketplace lists Sovos VAT Filing & Reporting, but the provided listing does not establish a public entry price.
Broad coverage spans indirect tax, e-invoicing, information reporting, and digital trust.
Supports complex multinational programs across nearly 200 countries and 19,000+ tax jurisdictions.
Offers a large integration ecosystem for ERP, AP, AR, accounting, and e-commerce environments.
Core platform pricing is quote-based, with no public starting price or plan comparison.
The broad portfolio can require careful module and product scoping during procurement.
User reviews describe some interfaces and troubleshooting workflows as complex.
Comarch is a Krakow-based software company with more than 6,500 employees, and its e-invoicing platform covers more than 60 countries for both accounts payable and receivable, with validation and archiving. Its home market advantage matters for KSeF, Poland's national e-invoicing system, which became mandatory in 2026. It integrates with SAP, Oracle, Microsoft Dynamics, NetSuite, Sage and Infor. Pricing depends on document volume, countries and integration effort, and there is no public entry price. G2 lists 17 reviews averaging 4.4.
Pricing: Comarch does not publish a standard entry price or self-serve tier. Official guidance says costs depend on document volume, countries and integration complexity. No verifiable public paid benchmark was found.
Covers AP and AR workflows, including OCR capture for suppliers that cannot send structured EDI.
Supports 60+ countries and direct connections to several national e-invoicing platforms.
Works with a wide range of ERP systems and preserves the customer’s existing core systems.
Pricing is custom and there is no publicly verifiable entry price or free trial.
Implementation can require a substantial project, especially across many countries, entities and ERP systems.
The breadth of configuration is better suited to enterprise buyers than small businesses seeking instant setup.
E-invoicing and tax-compliance infrastructure for software companies and platforms operating across multiple countries.
Invopop, founded in Madrid in 2021, gives developers one API to issue, receive and report compliant invoices in more than 30 countries, built on its open source GOBL invoice format. The Dev tier is free for 200 documents in one country with one user, and paid usage starts at €40 a month for 1,000 documents. Government connections are separate monthly apps, and Pro adds €500 a month. It integrates with Stripe, Chargebee and NetSuite, which suits SaaS companies that bill through Stripe and need Spanish, Italian or Portuguese invoices to clear.
Pricing: The Dev tier is free for 200 Pops, one country and one user. Paid usage starts at €40 per month for 1,000 Pops; government apps and integrations add separate monthly fees, while Pro adds €500 per month before Pops and Apps. Annual billing is discounted compared with paying monthly for 12 months.
A single GOBL-based integration supports country-specific formats, authorities and networks.
White-label embedding supports platforms that need compliant invoicing under their own brands.
Paid usage starts at €40 per month for 1,000 Pops, alongside a free 200-Pop Dev tier.
Total cost is difficult to estimate because Pops, countries, integrations and Pro features are billed separately.
The product is API- and developer-oriented rather than a conventional manual invoicing application.
Government apps generally add €300 per month after the first government app on a plan.
Fonoa, founded in 2019 and registered in Ireland, combines tax ID validation in more than 115 countries, tax determination in more than 190 jurisdictions, invoicing, e-invoicing and returns behind one API. Its customers include Uber, Canva, Netflix and Booking.com, which issue invoices to millions of buyers and sellers. It raised a $110 million Series C in May 2026. Pricing is usage-based and quoted, and G2 reviewers note costs grow with transaction volume. G2 lists 43 reviews averaging 4.6.
Pricing: Fonoa does not publish a price list or self-serve tiers; buyers engage sales for a quote. G2 reviewers describe pricing as usage-based and say costs can rise with transaction volume. Contract scope may vary by product, country coverage, transaction volume, and implementation requirements.
Covers validation, calculation, invoicing, reporting, and returns in one indirect-tax platform.
Supports tax determination across more than 190 jurisdictions and tax-ID validation across more than 115 countries.
Combines APIs for product teams with a web interface for tax and finance users.
Pricing is not public and reviewers say usage-based costs can increase with transaction volume.
Country coverage does not remove the need to confirm precise local filing and e-invoicing scope.
Implementation is sales-led rather than self-serve.
For years, e-invoicing in Europe meant sending structured invoices to government buyers. That changed in 2026, when several of the largest EU economies made it compulsory between businesses:
Belgium required B2B e-invoicing for VAT-registered Belgian businesses from January 1, 2026, using Peppol. A three-month tolerance period ended on March 31, 2026, and penalties can now apply.
Poland made its national system, KSeF, mandatory for B2B invoices from February 1, 2026 for the largest taxpayers and April 1, 2026 for most others. The smallest businesses follow on January 1, 2027.
France went live on September 1, 2026. Every VAT-registered business established in France must be able to receive e-invoices, and large and mid-sized companies must issue them. Smaller businesses must issue from September 1, 2027.
Germany has required businesses to be able to receive B2B e-invoices since January 1, 2025. Issuing becomes mandatory in 2027 for businesses with turnover above €800,000 and in 2028 for everyone.
Spain published the order that starts its B2B timeline in October 2026. E-invoicing will apply from October 2027 for businesses with turnover above €8 million and from October 2028 for the rest.
Outside Europe, Saudi Arabia, Malaysia, the UAE and most of Latin America have their own systems, and the UAE's mandate starts on January 1, 2027.
What ViDA means for the next four years
The EU's VAT in the Digital Age package, adopted in 2025, sets the direction for the rest of the decade. It allows member states to introduce domestic mandates without asking Brussels for permission, which is why national rules are arriving so quickly. From July 1, 2030, e-invoicing and near real-time digital reporting become mandatory for B2B transactions between EU member states.
ViDA uses the European standard for e-invoices, EN 16931, and most new national systems are converging on it and on Peppol. That is good news for buyers: a provider that handles Peppol and EN 16931 well will cover much of what is coming, with country add-ons for clearance systems such as KSeF, Italy's SDI and France's approved platforms.
Three models you will run into
Not all mandates work the same way, and the model determines what your software must do:
Model
How it works
Examples
Peppol exchange
Invoices go from the seller's access point to the buyer's access point
Belgium, Nordic public sector, Singapore, Australia
Clearance
The tax authority receives and validates each invoice before or as it is delivered
Poland KSeF, Italy SDI, Saudi Arabia, Mexico
Approved platform plus reporting
Invoices pass through certified private platforms that report data to the authority
France, with a similar five-corner design in the UAE and Slovakia
A provider might be excellent at one model and weak at another. Ask for a list of countries where it is directly connected or certified, not just where it says it is compliant.
How we chose these six
We reviewed the e-invoicing and indirect tax providers in our tax directory and grouped them by buyer: software companies embedding e-invoicing into their own products, startups and SaaS companies issuing invoices from a billing system, and multinationals connecting an ERP to many countries. We weighted country coverage and certifications, Peppol access, published pricing, developer experience, ERP integrations and reviewer feedback. Prices are as of October 2026.
Others to know: Avalara offers e-invoicing as part of its global indirect tax suite, Basware and Tungsten are long-standing AP networks, and many ERP vendors, including SAP and Microsoft, provide e-invoicing add-ons for their own systems. In France, check that any provider you use is, or partners with, a state-approved platform.

Which tool fits which company
Accounting or ERP software vendor. Storecove or Invopop. You need an API that lets each of your customers send and receive through one access point, with pricing that scales by document rather than by customer.
SaaS company billing through Stripe with customers in several EU countries. Invopop for direct integration with Stripe and Chargebee, or Fonoa if you also need tax ID validation and tax determination at scale.
Mid-size company with an ERP in a few EU countries. ONESOURCE Pagero or Comarch. Both connect to common ERPs and handle Peppol and the national systems. Choose Comarch if Poland is a major market.
Multinational with dozens of entities. Sovos or ONESOURCE Pagero, ideally alongside your indirect tax engine so invoice data and VAT returns reconcile. Clearance countries in Latin America and the Middle East are where these networks justify their price.
Small supplier whose large customer requires e-invoices. Use the free tier of the network your customer is on, such as ONESOURCE Pagero Free, or the e-invoicing features of your accounting software if it supports Peppol.
Getting ready for a mandate
Most failed rollouts are data problems rather than software problems. A practical sequence:
List every entity, VAT registration and invoice flow. Include intercompany invoices, credit notes and self-billing, which are often forgotten.
Clean master data. Mandates require correct VAT numbers, legal addresses and, in many countries, registered identifiers for every customer. Tax ID validation tools help.
Map invoice fields to EN 16931. Check payment terms, units of measure, tax categories and exemption codes.
Plan receiving, not just sending. In France and Germany, every business must receive structured invoices. Your AP team needs a process for invoices that arrive as data instead of PDFs.
Test with real trading partners. Run parallel sending before the deadline, and agree a fallback with key customers.
Archive correctly. Storage periods and formats are set by each country. Confirm where the provider stores invoices and for how long.
Questions to ask in a demo
In which countries are you directly certified or connected, and where do you use a partner?
Are you a Peppol access point, and do you support DBNAlliance for the US?
How do you handle rejections and status messages from tax authorities?
What does a new country cost to add, and how long does it take?
How are documents priced: per invoice sent, received, or both?
Where is data stored, and is archiving included?

Frequently asked questions
What is e-invoicing?
E-invoicing is the exchange of invoices as structured data, such as UBL or CII XML, that the buyer's system can process automatically. A PDF sent by email is not an e-invoice under EU mandates. Many countries also require the invoice to pass through a tax authority platform or an approved provider, which lets the authority see transactions in near real time.
When does France's e-invoicing mandate apply?
From September 1, 2026, all VAT-registered businesses established in France must be able to receive e-invoices, and large and mid-sized companies must issue them and send e-reporting data. Small and medium businesses and micro-enterprises must issue e-invoices from September 1, 2027. Invoices must go through a state-approved platform.
What is Peppol?
Peppol is an international network and set of standards for exchanging e-invoices and other procurement documents. Businesses connect through a certified access point, then can exchange invoices with anyone else on the network. Belgium uses Peppol for its B2B mandate, and many other countries use it for public sector invoicing.
What is ViDA?
VAT in the Digital Age is an EU legislative package adopted in 2025. It lets member states introduce domestic e-invoicing mandates without asking for EU approval, and from July 1, 2030 requires e-invoicing and near real-time digital reporting for cross-border B2B transactions within the EU.
Do I need e-invoicing if I am a US company selling into Europe?
Mostly not yet for French or Belgian domestic mandates, which focus on businesses established or VAT-registered in the country, though non-established companies may still have e-reporting duties. Your European customers may ask you to send invoices over Peppol, and Poland, Germany and others are tightening rules each year. Check each country where you hold a VAT registration.
How much does e-invoicing software cost?
Storecove starts at €3,300 a year plus usage and Invopop at €40 a month for 1,000 documents. ONESOURCE Pagero is free for up to 36 documents a year. Enterprise networks such as Sovos and Comarch price by countries, volume and integrations, usually as annual contracts.
Prices and ratings come from each vendor's public pricing pages and review sites as of October 22, 2026. Vendors change pricing often, so confirm with a quote. Nothing here is tax or legal advice.
