Qonto and Pennylane: Inside French Fintech’s Odd Couple

Two Paris-based fintechs sit at the centre of Europe’s small business banking race, and their relationship is more tangled than the headlines suggest. Qonto, founded in 2016 to handle SME banking, and Pennylane, founded four years later to handle SME accounting, are deeply integrated with each other: a Qonto account can flow directly into Pennylane’s books, and vice versa. They are also, increasingly, head-to-head rivals, because each has built an “all-in-one” stack that now covers the other’s original ground. The same European small business now has two plausible single-vendor options for banking, invoicing, bookkeeping, expense management, and short-term financing. The wider 2026 fintech landscape, from embedded finance to AI agents handling back-office tasks, makes this stack consolidation contest the year’s defining SME story (Top 5 Fintech Trends to Watch in 2026).

The contest is about to sharpen. France’s mandatory B2B electronic invoicing regime takes effect on 1 September 2026 for large and mid-sized companies, with SMEs and micro-companies following on 1 September 2027, according to the French government’s e-invoicing timetable. Every French business must be able to receive e-invoices from 1 September 2026. Whoever owns the platform that captures those flows owns a permanent seat at the SME’s financial table, and both Qonto and Pennylane know it.

Two Fintechs Sharing the Same Stack

Qonto and Pennylane serve overlapping markets in different shapes. Qonto sells business banking, corporate cards, bookkeeping tools, expense management, and short-term financing directly to small businesses. Pennylane started as accounting software for SMEs and their accountants, then layered on business bank accounts delivered through banking-as-a-service provider Swan. Each now sells itself as an “all-in-one” financial and accounting platform. The Tech.eu interviews with both firms lay out the friendship plainly (how Qonto and Pennylane operate as both partners and rivals).

The integration between them runs deeper than the product overlap. Pennylane’s co-founder and CEO Arthur Waller calls Qonto “probably the bank we are best integrated with.” A customer who wants a single back office can run a Qonto account through Pennylane’s books and have the data flow automatically. Waller’s framing is blunt: Pennylane is both friend and foe to Qonto, because “around three years ago, we also started offering our own bank account to our users.” Philippine Rougevin-Baville, Qonto’s managing director for Western Europe, prefers not to draw the comparison at all, calling Qonto and Pennylane “very, very different players” with different customer acquisition strategies, Qonto direct to SMEs and Pennylane via accountants.

Qonto’s Path to a Full Banking Licence

Qonto is the older and larger of the two by most measures. The company claims more than 600,000 SME and freelance customers across France, Germany, Italy, Spain, the Netherlands, Belgium, Portugal, and Austria. Qonto is full-year profitable, with revenue split roughly half from monthly fees and half from net interest income. Its most recent published valuation stands at $5bn, set during a 2022 funding round of $552m led by Tiger Global and TCV.

The next milestone is regulatory. Qonto applied for a French banking licence in 2025 and currently operates under a Payment Institution licence. The application is “making good progress,” Rougevin-Baville told Tech.eu, with “positive feedback” from the regulator and a hope of approval within six months. A full licence would let Qonto originate its own credit products, including lending, instead of relying on partners, and would deepen the moat against Pennylane’s bank-account offering delivered through Swan.

Qonto has used M&A to widen the moat already. It bought German rival Penta in 2022 and accounting and financial automation platform Regate in 2024. The application was filed with France’s ACPR regulator (Qonto’s ACPR banking licence application details).

Qonto has also publicly targeted 2 million customers by 2030 and says it will invest outside its native France for the rest of the year alongside the licence and e-invoicing work. The expansionist framing fits the 80-20 model Rougevin-Baville describes: 80% of the product is the same in each market Qonto enters, with a 20% local adjustment. Eight EU markets in under a decade is the proof point.

Qonto at a glance:

• 600,000+ SME and freelance customers across 8 EU markets
• $5bn last valuation, set in 2022 ($552m round led by Tiger Global and TCV)
• Full-year profitable, with revenue split ~50% monthly fees and ~50% net interest income
• Banking licence applied in 2025; ACPR decision hoped for within six months
• Two acquisitions completed: Penta (2022) and Regate (2024)

Pennylane’s $4.25bn Bet on Consolidation

Pennylane is younger but growing faster on paper. The company says it has more than 800,000 business customers, with around 90% of them coming via accounting firms rather than direct sales, a channel Qonto does not use at all. Earlier this year, Pennylane raised $4.25bn-valued $200m in a round led by TCV, with Sequoia and CapitalG also participating. The raise nearly doubled Pennylane’s valuation from $2.16bn in April 2025.

“We want to be in a position that we can sit at the table, so that if there is someone we would like to buy, to just be credible. You need to have hundreds of millions in the bank to sit at the table.”

Waller, who described himself as a fan of Qonto, was clear that the company did not need the cash to keep operating. He framed the war chest as a buy-side weapon for a French software market that is consolidating fast. Pennylane sees “super-app” competitors on the rise and US private equity firm Silver Lake making several investments in the same space. Pennylane also launched in Germany last year, its first overseas market, where Waller says it is “still very early days” but where “lots of demand” is showing up.

Why Pennylane raised $200m it did not need:

• To sit at the table for acquisitions in a consolidating French accounting-software market
• To defend against “super-app” competitors rolling up the SME accountant channel
• To match Silver Lake’s capital as the US firm takes multiple positions in the same space
• To fund the slower German rollout and any future country localisation work

The September 2026 E-Invoicing Trigger

The next inflection point is regulatory, not commercial. France’s mandatory B2B electronic invoicing reform opens with a staggered timetable set by the French government.

Large and mid-sized companies will be the first to feel it. SMEs and micro-companies get another year to issue, though they still need to receive from day one.

“There is obviously a battle between banks and accountants to equip their accountants with that operator.”

Both Qonto and Pennylane are chasing the slot. Rougevin-Baville describes e-invoicing as “a key topic for France in particular” that is also coming in other markets. Waller is more explicit about the contest, framing it as a fight between banks and accountants to equip the accountants with the operator role. Whoever becomes the approved platform for an SME’s invoices captures the data layer underneath, and that data layer feeds the lending, expense management, and cash-flow products both companies sell.

The wider cash-flow pain makes the slot commercially critical. The DGFIP’s stated objectives for the reform include cutting VAT fraud and shortening payment periods for French businesses, and the late-payment problem is severe enough that Pennylane’s own CFO has backed an AI receivables startup targeting it (Cleavr’s €1M raise for AI receivables in France). The September rollout opens with France’s largest companies first, which means Qonto and Pennylane are already pushing onboarding for the firms that will feel the obligation earliest.

France’s e-invoicing timetable:

1. 1 September 2026: obligation to receive electronic invoices applies to all companies established in France
2. 1 September 2026: obligation to issue electronic invoices applies to large companies and mid-sized companies (mid-caps)
3. 1 September 2027: obligation to issue electronic invoices applies to SMEs and micro-companies
4. 1 September 2026: e-reporting of transaction data to the tax administration begins on the same staggered calendar

Two Routes to Going European

The two companies take very different routes to expansion, and the difference shows up in how long it takes to add a country. Qonto runs what Rougevin-Baville calls an 80-20 model: 80% of the product is the same in each market it enters, with 20% localised. The model has carried Qonto from a French-only launch to eight EU markets in under a decade, and the German Penta acquisition in 2022 helped with the German rollout. Banking is mostly a regulated, mostly uniform product across the EU, and Qonto treats it that way.

Pennylane’s model is heavier. Waller says localising the accounting part of the tech for a new country can take Pennylane up to three years, because the company rebuilds the local tax and compliance layer from scratch. “Localising for a new country is much, much harder for us, as we are rebuilding the tax, so it is more to localise than just a bank account,” he said. Germany, launched in 2025, is Pennylane’s first overseas market, and Waller describes the country as still in early days. The 80-20 product philosophy and the three-year localisation model both point in the same direction even if they move at very different speeds. Qonto can enter a market and ship a banking product quickly, then add partners; Pennylane has to rebuild the back office before it can sell the front office.

Why Both Eyes Are on the Incumbents, Not Each Other

For all the talk of head-to-head competition, both executives frame the bigger contest as one against France’s incumbent banks and legacy accounting software. Rougevin-Baville points to “fewer threats” from new SaaS fintechs because banking is regulated, and says Qonto’s main job is to take share from the traditional players. Waller, when pressed on the Qonto rivalry, prefers to talk about Pennylane’s place in a market being reshaped by super-apps and Silver Lake.

That framing matters because it explains the cooperation. As long as the traditional banking and accounting incumbents hold most of the SME market, integration makes both companies bigger weapons against the real competitor. Qonto gets more in-product distribution through Pennylane’s accountant channel; Pennylane gets a fully regulated banking back end without the cost of applying for its own licence. As e-invoicing lands and consolidates the market, that cooperation may get harder to justify.

Waller’s clearest summary of the moment is also the simplest: Pennylane did not need the $200m it raised, but it wanted the balance sheet to dictate terms in a market that is consolidating around it. Qonto, meanwhile, is waiting on a banking licence that would let it originate its own credit products and finally match Pennylane’s stack with one of its own. The friend part still works. The foe part is no longer hypothetical.

It was last valued at $4.25bn in a 2026 funding round.

Are Qonto and Pennylane competitors?

Both companies publicly downplay the rivalry. Qonto’s Philippine Rougevin-Baville calls them “very, very different players” with different customer acquisition strategies. Pennylane’s Arthur Waller calls the relationship “friend and foe.” In practice, both now offer an all-in-one stack that overlaps in banking, invoicing, bookkeeping, and expense management, and both are competing for the operator slot under France’s new e-invoicing regime.

When does e-invoicing become mandatory in France?

The obligation to issue electronic invoices takes effect on 1 September 2026 for large and mid-sized companies, and on 1 September 2027 for SMEs and micro-companies. Every French company must be able to receive e-invoices from 1 September 2026 through a state-approved platform.

How are Qonto and Pennylane regulated?

Qonto currently operates under a French Payment Institution licence and has applied for a full banking licence with the ACPR, with a decision expected within six months according to Rougevin-Baville. Pennylane does not hold its own banking licence and offers bank accounts through Swan, a banking-as-a-service provider.
