E-invoicing software, also called electronic invoicing software, sends and receives structured invoices over networks such as Peppol and national tax platforms.
This guide ranks eleven products from European and other vendors on setup effort, the real price at your volume, how archives and identifiers leave, and whether you can buy and run it without an integrator.
Vendor money can buy visibility on this page and nothing else. No entry is softened, criticism is kept, and a click on a vendor link brings us no revenue. How that works.
In short
What e-invoicing software does
E-invoicing software creates, validates, delivers and archives invoices as structured data, so a buyer's system can read them and tax authorities can receive reports where a mandate applies.
Ranking criteria for this e-invoicing tool list, applied top to bottom: effort to get started, cost in practice, data return, ability to leave, buyer fit. One rule sits on top of those tests: places 1 to 3 go to challengers, vendors outside the best-known brands in a category, wherever the category has them; the established names follow from place 4 in their ranked order. Reasons for the choice of tests, and for skipping a score out of ten, can be read on the how we work page.
Spanish e-invoicing portal and API that starts with a free plan
Ranked #1 of 11 in Best E-invoicing Software in 2026.
Free tierPublished pricingEurope
The about page dates the company to 2003, and the terms name B2Brouter Global S.L. as the contracting entity. Prices are listed: Basic is free, Professional is 110 euro a year and Business 300 euro a year, plus tax.
Business adds legal archiving, ten users and other documents over Peppol. VeriFactu and TicketBAI reporting are manual on lower plans. The white-label API suits software vendors, though its price is not on the page.
What stands out
Free plan
Peppol
White-label API
Where it costs you
The free Basic plan stops at 24 transactions a year and 10 contacts, so any real invoice flow needs a paid plan.
Legal invoice archiving and bulk import are limited to the Business plan.
Right for
Small senders and software vendors wanting Peppol and local reporting without a sales cycle
Wrong for
Groups wanting a single global enterprise contract and SLA
SpainFree plan for 24 transactions a year; paid web plans billed annually, prices published
Stockholm Peppol access point sold in monthly message bundles
Ranked #2 of 11 in Best E-invoicing Software in 2026.
Published pricingEurope
Qvalia, based in Stockholm, sells Connect plans at 9 euro a month for 25 messages, 39 euro for 100, 99 euro for 1,000, and up to 899 euro for 30,000.
Large adds archiving and ERP connectors; API access starts at Medium. Plans bill monthly and cancel any time, so the exit is easy. Enterprise adds partner solutions and AI services but carries no listed price.
What stands out

Where it costs you
The Small and Medium plans cannot receive invoices, since receipt starts at Large.

Developer platform that turns billing data into compliant invoices through workflows
Ranked #3 of 11 in Best E-invoicing Software in 2026.
Free tierPublished pricingEurope
Invopop S.L. is registered in Madrid. The Dev plan costs nothing and includes 200 Pops; Pro costs 500 euro a month and adds unlimited users, support priority and an audit log.
Extra Pops are bought in bundles, from 40 euro a month for 1,000. Coverage lists over 30 countries, including Peppol, KSeF, SDI and Veri*Factu. The GOBL data format is published on GitHub under Apache-2.0, which eases leaving.

Peppol access point behind a single e-invoicing and reporting API
Ranked #4 of 11 in Best E-invoicing Software in 2026.
Pricing on requestEurope
Storecove shows a Peppol certified access point badge and presents one API for e-invoicing and e-reporting across 31 countries. A sandbox is offered for 30 days at no charge.
The site publishes no price list and links no pricing page, so budgeting starts with a sales conversation. It supplies the transport layer only, meaning approval workflows and ledger posting remain your own build.

Integration vendor from Bretten whose e-invoicing runs on its BIS platform
Ranked #5 of 11 in Best E-invoicing Software in 2026.
Pricing on requestEurope
SEEBURGER lists four e-invoicing services: the E-Invoicing Service, Invoice Delivery, Invoice Portal and a Peppol Access Point. Its page names Peppol, EESPA, KSeF, Chorus Pro and SDI as connections across over 35 countries.
The imprint places the company in Bretten, Germany. The savings of 60 to 80 percent against paper are the vendor's figure. Pricing is absent from the site.
What stands out

Where it costs you
No price list is published, so cost is known only after scoping.
The e-invoicing service sits within a broad integration platform, which lengthens the first project.

Ranked #6 of 11 in Best E-invoicing Software in 2026.
Self-hostablePricing on requestEurope
Comarch SA lists accounts payable, accounts receivable, multi-level validation, AI fraud prevention and an e-archive in one system. The vendor says SaaS runs in its certified data centres, while on-premise buyers pay a one-time licence plus server and storage.
Subscription pricing follows document volume, countries and integration effort. It is described as a certified Peppol Access Point and OpenPeppol member.

Valencia-rooted EDI group with a certified Peppol access point
Ranked #7 of 11 in Best E-invoicing Software in 2026.
Pricing on requestEurope
EDICOM describes a single SaaS platform and says it is a certified Peppol access point, with country coverage quoted as 80 or 85 and more depending on the page section. Regulatory updates arrive without extra maintenance charges.
The page gives no prices and no trial, only free demos, and its origins in EDI mean the product talks in terms of trading partners and mandates more than of simple invoicing screens.
Invoice network whose old domain now redirects to Thomson Reuters
Ranked #8 of 11 in Best E-invoicing Software in 2026.
Free tierPublished pricingEurope
The pagero.com address now forwards to europe.thomsonreuters.com, where the product is called ONESOURCE Pagero. A free offer exchanges up to 36 documents a year before fees may apply, and some document types may be blocked by local rules.
The network page claims accredited Peppol service provider status wherever Peppol runs. Fees after the allowance are not published, and buyers should read the new owner's contract terms.

Pricing on requestEurope
Esker handles supplier invoices and customer invoices in the same platform and lists EDI, Peppol and interoperability support across more than 60 countries. Capture, validation, status tracking and compliant archiving are part of the stated scope.
The site names no price and no trial, only a demo and a calculator. E-invoicing here is a module of a wider finance automation suite, so a buyer wanting just delivery pays for context.

Invoice network operator with 190-plus countries covered and an enrichment layer

Basware Oy lists an e-Invoicing Network for receiving, sending, enrichment, archiving and interoperability, and says it covers 190+ countries and has processed 2.5B+ invoices.
It does not mention a Peppol access point on its main page, so confirm that by name before relying on it. No prices or trial are stated. The offer is built for procurement-heavy enterprises, which makes a one-person firm an awkward fit.

E-invoicing software creates, validates, delivers and archives invoices as structured data, so a buyer's system can read them and tax authorities can receive reports where a mandate applies. The differences that matter are rarely in the feature list, so this is the order we would work through them.
01
Work out how much a sales call is worth to you
7 vendors on this page sell by quote, while 4 publish a pricing model you can read today: B2Brouter, Qvalia, Invopop, ONESOURCE Pagero (Thomson Reuters).
02
Decide how much the jurisdiction matters
The vendors on this page are based in 8 countries (Europe 10, Elsewhere 1). The country of the contracting company sets which authorities can ask it for your data, whatever the hosting region.
How e-invoicing software differs from invoicing software
Invoicing software creates a document for your customer; e-invoicing software makes sure a structured copy reaches the buyer's system through a network that both sides accept. Storecove, Qvalia and Edicom present themselves as access points, meaning the delivery layer, while Esker and Basware add capture, validation and archiving for payables. Invopop works from the other side, taking data from your billing system and running it through workflows.
Decide first which job you are buying: sending, receiving, reporting to a tax authority, or all three, because few products are strong at every one and the answer shapes the shortlist. Then check whether the vendor names the networks you need, such as Peppol, Chorus Pro, SDI or KSeF, instead of stating a country total, since a headline figure says little about the one country your customers sit in.
List the networks and national platforms your customers require
Ask whether the vendor is itself the access point or resells one
Separate sending, receiving and tax reporting in your requirements
Pricing: published tiers against quoted contracts
Only some vendors show prices. B2Brouter lists a free plan and two annual plans, Qvalia lists monthly bundles by message volume, and Invopop lists credits and a monthly fee per country. SEEBURGER, Comarch e-Invoicing, Edicom, Esker and Basware show none, and Tradeshift's pricing page returned not found.
Volume is the main variable: Pagero's free offer ends after 36 documents a year, B2Brouter's after 24 transactions. Count what you really send and receive in a month, including credit notes and tax reports, then compare the plan ceiling. Ask quoted vendors for a written price at your volume and the cost of every additional country, and ask what happens to the price in a year when your document count has grown.
Count documents per month including credit notes
Check the ceiling of the plan you would start on
Get the per-country fee in writing
Mandates and the effort of switching
Mandates reshape the deadline more than the product. Tradeshift states it is registered as a French PDP, B2Brouter says it is a Plateforme Agréée, and Invopop lists Veri*Factu, KSeF, SDI and ZATCA among its connections. A vendor that is registered with the authority carries the reporting for you; a plain access point may not.
Implementation time differs widely: Comarch quotes about six to eleven weeks for mid-sized firms, while Qvalia and B2Brouter sign up online, so the effort you budget differs by an order of magnitude. Run a test with one customer before the mandate date, because format errors surface only on real documents, and ask who fixes a rejected invoice, you or the vendor.
Confirm registration status for each country with a mandate
Ask for the implementation timeline in writing
Test one live customer before the deadline
Leaving a provider and keeping control
Exit has two parts: your archive and your network identity. Qvalia bills monthly and can be cancelled at any time, B2Brouter keeps invoices for the legal period on paid plans, and Invopop publishes its GOBL format under Apache-2.0. For the others, ask how archived invoices are exported and whether your Peppol identifier can move to another access point.
A vendor owned by a larger group, such as ONESOURCE Pagero under Thomson Reuters, may change contract terms after a sale. Keep a copy of the structured XML for every document, since a PDF alone does not satisfy most tax authorities, and test a full export before you sign a multi-year contract.
Ask for a bulk export of archived structured invoices
Check whether your network identifier can move
Read change-of-control terms in the contract
What goes wrong most often when buying e-invoicing software
Treating a PDF sent by email as e-invoicing in a country where the buyer needs structured data.
Comparing monthly prices without counting credit notes, received invoices and tax reports against the plan ceiling.
Assuming one vendor's country list covers every mandate, when coverage differs by network and by type of document.
Waiting for the mandate month to test a live invoice with a real customer.

Frequently asked questions

What is the best e-invoicing software in 2026?
Our ranking of 11 puts B2Brouter first. B2Brouter Global S.L. runs a web portal, ERP connectors and a white-label API on one platform, and the Basic plan costs nothing but counts sent invoices, received invoices and tax reports against 24 transactions a year.
