Invoice Tools Providers in Europe

SumUp

SumUp is a payments company built for the merchants traditional providers never bothered with. Founded in 2012 and headquartered in London, it sells low-cost card readers and point-of-sale hardware to small businesses — market traders, cafés, hairdressers, tradespeople — who could never justify the monthly fees, multi-year contracts, and cumbersome terminals that legacy processors demanded. The core proposition has barely changed since launch: buy a card reader outright for a modest one-off price, pay a small percentage per transaction, and sign nothing. That model has scaled a long way past its origins. SumUp now serves more than 4 million merchants across roughly 35 markets, employs around 4,000 people, and was valued at about €8 billion in a 2022 round led by Bain Capital. In 2024 it raised a €1.5 billion private credit facility led by Goldman Sachs, and it has been weighing a stock market listing that could value it as high as $15 billion. The more significant shift is that SumUp is no longer a card reader company. Through a run of acquisitions — Payleven, the e-commerce platform Shoplo, the core banking provider Paysolut, POS software firm Tiller, and the US loyalty startup Fivestars — it has assembled a full financial stack for micro-businesses: a business account and card, invoicing, an online store, loyalty tools, self-service kiosks, and SDKs for developers who want to embed card acceptance in their own products. The ambition is to be the only software a small merchant needs to run their business. That leaves SumUp in an unusual competitive position. On hardware and in-person payments it faces Square, Zettle, and Dojo; as a broader business platform it edges toward Stripe, Mollie, and Revolut Business. Its defensibility rests on the segment most of the industry finds too small to serve properly — the micro and nano merchants that make up the long tail of European commerce.

Silvr

Silvr is a digital banking platform built specifically for the self-employed and freelance economy. The company targets creators, gig workers, and independent professionals who fall through the cracks of traditional banking—people running legitimate businesses but operating outside conventional employment structures. Rather than forcing them into generic business bank accounts designed for SMEs, Silvr offers tailored financial tools that actually reflect how modern independent work operates. The platform combines a business current account with integrated financial management features: invoicing, expense tracking, tax planning, and automated bookkeeping. Silvr handles the friction points that plague freelancers—irregular income patterns, complex tax obligations, cash flow volatility—by building visibility and automation directly into the banking layer. It's not a neobank trying to be all things to all people; it's purpose-built around the specific financial rhythm of self-employment. In a market dominated by legacy banks treating freelancers as afterthoughts and generic challenger banks treating them as just another customer segment, Silvr occupies a distinct position. It understands that the self-employed need different banking primitives, not just a prettier interface. The company sits at the intersection of business banking, fintech, and the creator economy—a segment the traditional sector has largely ignored. Silvr represents a broader fintech trend toward hyper-segmentation and behavioral specificity. Rather than chasing scale through mass-market appeal, it's building moat through deep product fit with an underserved but economically significant cohort.

Paysera

Paysera is a Lithuanian fintech company that has quietly built one of Europe's most comprehensive payment and banking platforms, serving millions of users across the continent. Rather than chasing hype, Paysera focuses on practical utility—combining payment processing, digital accounts, currency exchange, and invoicing tools into a single interface that works across borders and languages. The platform powers everything from freelancers managing invoices to SMEs handling payroll, while also offering consumer-facing services like multi-currency wallets and competitive exchange rates. What sets Paysera apart is its unglamorous pragmatism: it solves real friction in how Europeans move, spend, and manage money across different countries, without the startup theatrics. It's the kind of company that doesn't dominate headlines but has become indispensable infrastructure for a significant portion of the continent's digital economy. In the crowded European fintech landscape, where newer players chase consumer attention and legacy banks chase compliance, Paysera operates in the profitable middle—trusted by businesses and individuals who value reliability and cross-border simplicity over brand prestige.

Blackcat

Blackcat is a German fintech platform designed to help freelancers and self-employed professionals manage their finances with minimal friction. Rather than forcing users into complex accounting workflows, Blackcat simplifies the entire money flow—from invoicing to tax filing—with a mobile-first interface that feels more like a consumer app than enterprise software. The platform tackles a real pain point in the European freelance economy: most existing tools are either bloated legacy systems or fragmented point solutions that don't talk to each other. Blackcat bundles invoicing, expense tracking, tax preparation, and business banking into one coherent experience, removing the cognitive load of juggling multiple services. What sets Blackcat apart is its opinionated approach to simplicity. Rather than mirroring traditional accounting software's feature sprawl, it prioritizes the workflows that matter most to freelancers—getting paid faster, documenting expenses, and staying tax-compliant without the headache. The platform's integration with German tax authorities and compliance frameworks positions it as particularly valuable in the DACH region, where self-employed taxation can be notoriously complex. In a market crowded with accounting tools and SME platforms, Blackcat represents a new generation of fintech that starts with the freelancer's actual needs rather than retrofitting legacy processes into a digital wrapper. It's part of a broader shift toward consolidated SME finance platforms that understand that complexity itself is the problem.

Spendesk

Spendesk cuts through the chaos of corporate spending. It's a unified platform where teams manage expenses, issue corporate cards, approve invoices, and reconcile everything in one place—no more spreadsheets shuffled across email chains or finance teams drowning in admin work. The platform sits somewhere between a spend management tool and a modern finance operating system. Companies connect their bank accounts, set spending rules, issue virtual or physical cards to employees, and watch transactions flow into an automated approval workflow. Invoices get coded automatically. Reconciliation happens in real time. The whole thing syncs with accounting software so the numbers always match reality. What makes Spendesk different is that it treats spend management as a team sport, not a back-office chore. It's built for the actual workflows that modern finance teams use: expense reports that don't feel like punishment, card management that doesn't require IT involvement, and visibility that doesn't require a Ph.D. in Excel. Most competitors bolt features together; Spendesk designed the experience first. In a market crowded with point solutions and legacy software masquerading as modern, Spendesk has become the de facto standard for mid-market companies in Europe that want to stop thinking about spending and start optimizing it. It's now a critical piece of infrastructure in how thousands of companies handle money.

SeedLegals

Legal documents are one of the largest hidden costs of running a startup. Founders spend tens of thousands of pounds with law firms producing the term sheets, shareholder agreements, employee option schemes, and funding round paperwork that every growing company needs but few founders understand well enough to procure efficiently. SeedLegals was founded in London in 2016 to bring that legal infrastructure online. Its platform automates the creation of startup legal documents — fundraising agreements, employee equity, board resolutions, EMI option schemes — through a guided interface that produces lawyer-quality documents in hours rather than weeks, at a fraction of the cost. The product is grounded in genuine legal expertise — SeedLegals works with law firms and corporate lawyers to ensure the documents it produces meet the standards of the funds and investors that ultimately need to sign them. SeedLegals has become deeply embedded in the UK startup ecosystem, processing a significant share of EIS and SEIS funding rounds and supporting thousands of UK companies through their early-stage equity events. In the European startup infrastructure landscape, where regulatory and legal complexity varies significantly between markets, SeedLegals' UK depth represents the most mature example of legal automation for early-stage companies — a model that is gradually expanding to other European jurisdictions.

Indy

Indy is a French fintech built for freelancers and self-employed workers who are tired of juggling accounting software, invoicing tools, and bank dashboards across a dozen different apps. The platform consolidates business banking, invoicing, expense tracking, and tax compliance into a single workspace designed specifically for French independent professionals and micro-entrepreneurs. Unlike traditional accounting software that feels built for accountants, Indy puts the solopreneur first—automating routine tasks like categorizing expenses and calculating quarterly tax estimates while keeping the interface clean and approachable. The company has become a go-to solution across France for freelancers managing both the creative and administrative sides of their business, from photographers to consultants to digital agencies. It's one of Europe's clearest examples of how fintech can solve a specific, underserved market by building exactly what that market actually needs rather than trying to be everything to everyone. In a landscape crowded with generic SME finance platforms, Indy's laser focus on French self-employed workers—and their particular regulatory requirements and pain points—has established it as a cultural fixture in the French freelance community.

Tradeshift

Tradeshift runs the operating system for global commerce—a cloud platform that lets businesses transact with each other in real time, from purchase orders to invoices to payments. It's built for a world where finance teams spend less time on manual reconciliation and more time on strategy, where supply chain visibility is instant, and where cash flow stops being a guessing game. The company sits at the intersection of procurement, invoice management, and working capital, connecting enterprises with their supplier networks. Rather than forcing companies to adopt yet another SaaS tool, Tradeshift embeds itself into the workflows that already exist—automating the grunt work of B2B commerce that still happens through email, spreadsheets, and PDF attachments. Trodeshift's positioning is distinctly European: it understands the complexity of multi-regional supply chains, VAT compliance, and the regulatory layers that global companies navigate daily. While American fintech still obsesses over consumer-facing dashboards, Tradeshift has spent years building the unglamorous but essential plumbing that keeps enterprise trading flowing. In an era where digital transformation is finally table stakes for large corporates, Tradeshift has become infrastructure—the kind that companies discover they can't function without. It's not the flashiest story in fintech, but it's one of the most resilient.

bnext

bnext is a Spanish neobank built for the self-employed and small business owners who've outgrown traditional banking but don't need enterprise complexity. It strips away the bloat of legacy banks and focuses on what actually matters: a mobile-first account, competitive forex rates, and transparent fees with no surprise charges. The platform handles invoicing, expense tracking, and basic bookkeeping alongside core banking, positioning itself as a unified workspace rather than just another digital bank. Where established institutions still treat SMEs as afterthoughts, bnext treats them as the primary customer. It's designed for the freelancer checking balances between client calls and the startup founder who wants one dashboard instead of five browser tabs. The company has carved out real traction in Spain and increasingly across Europe, proving there's genuine demand for banking that actually understands how modern small business works.

Tax Free

Tax Free is a B2B SaaS platform that simplifies VAT reclamation for international businesses. Most companies lose thousands annually to complex VAT compliance across borders—Tax Free automates the entire process, from documentation to submission, turning compliance overhead into recovered cash. Built for e-commerce merchants, SaaS platforms, and service providers operating across multiple European jurisdictions, it handles the messy work of tracking eligible expenses, calculating VAT positions, and filing claims with regional tax authorities. Rather than hiring tax consultants or wrestling with spreadsheets, customers connect their accounting systems and let Tax Free's intelligence layer handle jurisdiction-specific rules, deadlines, and documentation requirements. The platform sits quietly in the financial backend but unlocks material capital recovery that most businesses simply abandon. It's part infrastructure, part compliance, part cash management—solving a problem that affects every company doing cross-border business in Europe. In a landscape where VAT complexity remains one of the last major inefficiencies in SME finance, Tax Free turns hidden liabilities into automated revenue recovery.

ANNA Money

Business admin is the part of running a company that nobody starts a business to do. Invoicing, tax filing, expense management, and the general administrative overhead of being a legitimate business entity in the UK are simultaneously essential and relentlessly time-consuming for the freelancers and small business owners who have to deal with them. ANNA Money was founded in London in 2017 — the name stands for Absolutely No Nonsense Admin — with a direct mandate to automate as much of that overhead as possible. Its business account combines a Mastercard, invoicing tools, tax estimation, expense categorisation, and a smart assistant that handles routine admin tasks, targeting the sole traders and micro-businesses who are the most underserved segment of the UK business banking market. The tone is deliberately irreverent — the brand uses a cat as its mascot and communicates in a register that is the opposite of corporate banking language. That positioning is not just aesthetic; it reflects a genuine product philosophy that the administrative burden on small businesses should be reduced, not monetised. In the UK business banking market, where Monzo Business, Tide, and Revolut Business compete for the same customers, ANNA has carved out a distinctive position through product depth in the admin automation layer.

Countingup

Sole traders and micro-businesses in the UK spend a disproportionate share of their working time on financial administration — bookkeeping, invoicing, VAT returns, self-assessment — tasks that add no value to the business but carry real consequences if done incorrectly. Countingup was founded in London in 2017 to eliminate that administrative burden with a business current account that has bookkeeping built directly into the product. Rather than connecting a bank account to a separate accounting app, Countingup combines them from the start — transactions are automatically categorised, VAT is tracked in real time, and tax estimates are updated continuously based on actual income and expenses. The integration removes the synchronisation problems, subscription costs, and manual reconciliation that define the experience of running a separate bank account and accounting product. Countingup targets the UK's five million sole traders and micro-businesses — a segment that has been chronically underserved by both traditional banks and accounting software companies that design for businesses larger than they are. In the UK SME fintech landscape, where Tide, ANNA, and Starling Business compete for the same customers, Countingup's vertical integration of banking and accounting is a product differentiator that is difficult to replicate without rebuilding both layers simultaneously.
