Pennylane and accountant: a transformed customer relationship

Updated April 4, 2026 - The collaboration between a Pennylane chartered accountant no longer stops at the annual exchange of accounting documents. Since its creation in 2020, Pennylane has become one of the main collaborative accounting software in France, with more than 3,000 partner firms and a fundraising of 175 million euros in January 2026 intended to consolidate its position as European leader in financial OS. This platform concretely transforms the relationship between the manager and his firm: documents circulate in real time, cash flow is visible daily, and exchanges pass from an annual rhythm to continuous monitoring.

In summary: Pennylane is collaborative accounting software that connects clients and firms on a single platform. It enables instant sharing of supporting documents, real-time cash flow monitoring, electronic invoicing preparation and personalized dashboards. For the accountant, it's a service quality lever. For the manager, it's permanent visibility over their numbers.

Pennylane is an accounting and financial management platform designed specifically for small businesses, SMEs and the accounting firms that support them. Unlike traditional accounting software, Pennylane is based on a collaborative architecture: the client and their accountant work in the same environment, with differentiated rights and shared visibility.

The numbers speak for themselves. In January 2026, Pennylane raised 175 million euros, one of the largest fundraisings in French Tech history in the accounting software sector. This valuation reflects a market reality: more than 45,000 companies and 3,000 firms already use the platform according to the publisher's official data.

The reasons for this enthusiasm are multiple:

• Centralization of flows: bank, invoices, expenses, VAT and payroll converge to a single entry point.
• Intelligent automation: automatic matching, OCR invoice recognition and recurring entries reduce manual entry by 70 to 80%.
• Integrated client portal: the manager accesses their accounts, documents and indicators without soliciting their firm by email.
• Electronic invoicing preparation: Pennylane is a certified PDP partner (Partner Dematerialization Platform), which guarantees compliance with the RFE reform planned for September 2026.

When a firm equipped with Pennylane connects its clients to the platform, the very nature of the relationship evolves. The manager no longer waits for their annual report to know the health of their business. They have permanent access to accounting data, which changes their expectations.

Real-time cash visibility#

The cash dashboard is undoubtedly the most appreciated feature by managers. It aggregates bank balances, VAT deadlines, pending invoices and flow forecasts. As a result, the manager can anticipate their management decisions on a daily basis, rather than after the fact.

Simplified document tracking#

No more exchanging documents by email, PDF files lost in inboxes and reminders to obtain a missing invoice. On Pennylane, the client deposits their supporting documents directly from the mobile application or web portal. The firm finds them sorted, ready to be integrated. The time saving is estimated at 3 to 5 hours per month for a standard small business.

Smoother and more fréquent exchanges#

The messaging integrated into the platform allows you to ask an accounting, tax or social question directly in the context of the file. No need to recall the subject or attach documents: everything is already there. This fluidity encourages regular exchanges and transforms the relationship from an annual meeting into continuous support.

Active piloting rather than endured#

Personalized dashboards allow the manager to follow their favorite KPIs: gross margin, customer payment period, expense ratio, turnover evolution. The accountant can configure these indicators in advance and comment on them during regular meetings. Accounting becomes a management tool, not just a legal obligation.

Several factors are converging to accelerate the adoption of collaborative platforms like Pennylane by French accounting firms.

Electronic invoicing reform#

Electronic invoicing between businesses comes into progressive application from September 1, 2026. All companies subject to VAT will have to issue and receive their invoices in electronic format via a dematerialization platform. Pennylane, as a certified PDP, positions firms that use it ahead of this obligation. This is a major commercial argument for accountants who wish to support their clients in this transition.

Growing demand for real-time management#

SME and small business managers are increasingly demanding about the frequency and quality of financial information. According to a 2025 study by the Order of Chartered Accountants, 68% of managers surveyed want real-time access to their accounting data, compared to 42% in 2022. This 26-point gap in three years reflects a profound change in expectations.

Competition from online firms#

Online accounting firms have generalized the use of collaborative tools since their creation. For traditional firms, the adoption of platforms like Pennylane has become a compétitive necessity. Not offering a client portal in 2026 risks appearing outdated compared to competitors who offer a smooth digital experience.

Having the tool is not enough. The quality of the customer relationship depends on how the firm and the manager organize their collaboration on a daily basis.

Define the responsibilities of each party#

This is the most critical point. Who enters the invoices? Who validates the entries? Who declares VAT? These questions must be resolved from the start of the platform implementation and formalized in the engagement letter. Without this clarification, the risk is double: either the firm does the client's work, or the client makes entry errors that the firm will have to correct.

Here is a typical distribution of responsibilities on Pennylane:

Set an adapted monitoring rhythm#

Continuous collaboration does not mean permanent availability. It is essential to define an exchange schedule:

• Weekly: quick check on cash flow and emergencies (ideal for companies in startup phase or in tense situations).
• Monthly: complete accounting review with analysis of variances and trends (standard for most small/medium businesses).
• Quarterly: strategic point with forecasting and adjustments (suitable for stable companies with reliable accounting history).

Do not cumulate communication channels#

The most fréquent mistake is to continue exchanging documents and questions by email when the platform offers a dedicated channel. This duplication creates confusion, loss of information and frustration on both sides. The rule must be simple: everything concerning accounting goes through Pennylane. Emails are reserved for external subjects (legal, complex tax, strategy).

Hayot Expertise advice: the tool only positively transforms customer relations if the rules of collaboration are clear: who submits what, who controls what, and at what pace the information is reviewed. A firm that imposes an organizational framework from the start avoids 80% of future friction.

Some traps recur systematically when implementing collaboration via Pennylane between a client and their accountant.

** Pennylane will accelerate a good process and amplify a bad one. Start by defining who does what before connecting the platform. ** A client who doesn't know how to deposit an invoice or read their cash dashboard will derive no benefit from the platform. Plan a 30-minute training session at startup. ** The coexistence of two channels for the same subjects creates confusion and frustration.

Cut cleanly: accounting lives on Pennylane. ** Having access to real-time numbers is useless if no one looks at them. Schedule a monthly 20-minute meeting to comment on indicators. ** Verify that access rights are properly configured: the client should not be able to modify validated accounting entries, and the firm must have a complete view. ** If your firm uses Pennylane, make sure the RFE module is activated and that your clients are informed of the reform deadlines.

Pennylane is particularly well suited to the following profiles:

• Small businesses with 1 to 20 employees with a service, trade or craft activity.
• Startups and scale-ups who need financial visibility for their investors.
• Freelancers and liberal professions who want simple and automated accounting.
• Growing SMEs who need dashboards and regular cash flow monitoring.

However, the following structures may need complementary tools:

• Holdings and groups with complex consolidations.
• Industrial companies with advanced production management (cost prices, work in progress, bills of materials).
• Very specific activities (construction with work situations, catering with perishable stock management) which require specialized business modules.

In these cases, Pennylane can remain the main accounting base, but will need to be supplemented by specialized tools via its API integrations.

In 2026, the relationship between a client and their Pennylane chartered accountant no longer resembles what it was five years ago. Collaboration has become continuous, data is accessible in real time, and exchanges are smoother. But this transformation only produces its benefits if it is accompanied by rigorous organization: clear responsibilities, defined monitoring rhythm, and exclusive use of the platform for accounting exchanges.

Managers who play the digital collaboration game notice a tangible improvement in service quality: fewer delays, fewer errors, more visibility and a strengthened relationship of trust with their firm. The tool is only a support. It is the quality of human collaboration that makes the difference.
