Online Accountant for SASU Founders
Digital accounting for SASU founders: bookkeeping, VAT, expense claims, founder pay, dividends, payroll, cloud tools and clear support for solo company management.
Loading…
The need for an online accountant for a SASU when you want a firm that can manage the company remotely without turning the relationship into a faceless platform. Behind that search, the same expectations usually appear: simple tools, fast answers, clean bookkeeping, a clear view of the founder's compensation and confidence that nothing important will be missed.
SASU is popular with solo founders because it is flexible. That same flexibility creates recurring questions: should the president take a salary right away or wait, how should expenses be documented, when does payroll become necessary, how should VAT work, what about shareholder current accounts, dividends or the first hire? A good online firm needs to answer those questions clearly, without jargon and without sending the founder to ten different contacts.
The focus here is a specific transactional need: finding a digital accounting firm built for SASU operations, not just a low-cost bookkeeping interface. The right setup combines automation, reliable compliance and real advice on founder-level trade-offs.
What a SASU founder really expects from an online firm#
Simplicity in day-to-day operations#
Bank feeds, sales invoices, expense claims, purchase documents, VAT follow-up, dashboards and reminders should feel smooth. If the founder still has to rebuild everything manually, the digital promise has failed.
Clear answers on founder compensation#
In a SASU, the most sensitive topics often revolve around the president: salary or no salary, dividends, reimbursed expenses, shareholder current account use, cash trade-offs and social protection. Those topics need advice, not just software.
A setup that can keep up with growth#
Many SASUs start with limited flows and then evolve quickly: higher revenue, more expenses, a first hire, financing needs, a move toward a multi-shareholder SAS or a broader wealth-structuring question. The right online firm should be able to support that transition.
The issues that most often create problems in SASU#
No salary at first, then late regularization#
Many founders start without paying themselves and then try to adjust later. Without scenario work and a calendar, compensation choices become reactive instead of deliberate.
Expenses that are weakly documented#
Meals, equipment, software subscriptions, travel, coworking, phone bills and computers all need to be properly justified and linked to the business. This is a classic source of disorder in poorly managed SASUs.
VAT, invoicing and legal formalities handled too late#
A SASU does not only need annual accounts. VAT has to be monitored, invoicing has to be organized, documents need to be stored, annual decisions have to be prepared and the next months need a clean accounting base. With e-invoicing on the horizon, that structure matters even more.
How a good online accountant works for a SASU#
1. Set up the tools and the flow of documents#
We structure the bank connection, invoicing, collection of documents, expense handling and control points. The goal is to reduce admin time without losing accuracy.
2. Keep accounting and tax work reliable#
Bookkeeping, VAT, annual accounts, founder obligations and administration exchanges need a solid base. A digital firm only adds value if that base stays robust.
3. Help with founder trade-offs#
We work on the real SASU decisions: salary, dividends, expense claims, shareholder current account, first hire, social protection and cash projections under different scenarios.
4. Provide a useful management reading#
Even for a small company, it helps to track revenue, margin, available cash, what needs to be reserved for taxes and contributions, and the impact of compensation changes. That is often the difference between a well-run SASU and a stressful one.
Who this page is for#
This section is useful if you are in one of these situations:
- a freelancer or consultant operating through a SASU with little admin time available;
- a founder who wants a fully digital firm but not a fully standardized one;
- a new SASU owner deciding between salary, dividends or no pay at the start;
- an entrepreneur who wants accounting, invoicing and cash follow-up to work together;
- a growing SASU preparing to hire or bring in another shareholder.
What you should get in the first 90 days#
The beginning of the assignment should already make life easier:
- the right tools and document flows configured;
- a clear calendar of accounting, tax and legal obligations;
- better visibility on expenses and VAT;
- an initial view of founder compensation choices;
- a simple dashboard for cash and profit;
- a roadmap for the next 6 to 12 months.
A good online SASU accountant does not just sell access to a dashboard. The value is a reliable setup, quick answers and clear founder-level decisions when they actually matter.
Founder compensation in a SASU: the three levers#
The SASU president has three main compensation levers, and the optimal mix depends on stage and personal situation:
1. Salary (rémunération de président): classified as "assimilated employee" pay. Subject to ~80% employer-and-employee social charges on gross. Provides full social cover (health, retirement, provident) but no unemployment cover. Useful when the founder needs to validate retirement quarters or qualify for personal credit.
2. Dividends: distributed after IS on retained profit. Subject to the 31.4% flat tax (PFU — 12.8% income tax + 18.6% social charges), with no employer social charges. Generally more efficient than salary in pure net terms, but only available after IS has been paid (15% on the first €42,500, 25% beyond).
3. ARE + no salary: the SASU founder can register for unemployment after a rupture conventionnelle and keep 100% of their ARE benefits as long as they take no director salary. Profits are retained in the SASU and distributed later as dividends. This is a powerful 18-24 month strategy for new founders.
We model the three options every year, factoring in your age, family situation, remaining ARE rights, target take-home and retirement strategy.
Shareholder current accounts and cash circulation#
A SASU founder can lend cash to or draw cash from their own company through the compte courant d'associé (shareholder current account). The rules:
- Cash injections (founder loaning the company) earn deductible interest at the official rate (around 5% in 2026), capped by the taux de référence published by the tax administration.
- Withdrawals (founder taking cash from the company) must be repaid or qualified as dividends, salary or reimbursement of advances. A negative current account is a major audit flag and can trigger requalification as concealed remuneration.
- Annual interest on the current account is a tax-deductible expense, but subject to thin-capitalisation rules above certain thresholds.
We track the shareholder current account monthly and flag any drift early.
VAT, e-invoicing and the 2026 obligations#
A SASU above the franchise-en-base threshold (€37,500 for services, €91,900 for goods in 2026) must register for VAT and file monthly or quarterly returns. The 2026 e-invoicing reform adds new obligations:
- September 2026: all VAT-registered businesses must be able to receive e-invoices via an approved platform (PDP — Plateforme de Dématérialisation Partenaire); the PPF (Portail Public de Facturation) no longer handles invoice exchange.
- September 2026 (large companies first): progressive obligation to issue e-invoices via the same platforms.
- B2C transaction reporting: B2C sales data must be transmitted to the tax authority at the agreed cadence (e-reporting).
We set up the right PDP integration (Pennylane, Sage, QuadraFact) and train the founder before the obligation kicks in.
Common pitfalls in a SASU#
1. Mixing personal and business cash#
The SASU founder who pays personal expenses from the business account creates an abus de biens sociaux risk and complicates the close. We set up a clean split from day one.
2. Not building a dividend track record#
Dividends are only attractive when the SASU has a multi-year history of distributable profit. Founders who pull cash too early through current-account drawings lose the tax efficiency of the dividend route.
3. Missing the décision unique de l'associé (DUA)#
Each year, the SASU founder must adopt an annual decision approving the accounts, the result allocation and any dividends. Skipping this step is a corporate-governance error that can void the dividend distribution.
4. Ignoring the acompte d'IS schedule#
SASUs with significant profit pay IS through four quarterly instalments. Missing an instalment triggers penalties. We embed the schedule in the cash plan.
5. Underestimating the cost of first hire#
The first salaried hire transforms the SASU's cost structure: payroll, DSN, mandatory health and provident schemes, professional liability insurance. We model the full cost (gross + ~42-45% employer charges + ancillary obligations) before the hire decision.
Running a SASU From Abroad as a Non-Resident President#
A SASU works well for foreign founders precisely because nothing in its structure requires you to live in France. The president can be a non-resident, the onboarding can be fully online, and the bookkeeping runs on a collaborative platform (Pennylane) that you reach from anywhere, day or night. Documents are signed electronically through DocuSign, bank feeds and receipt capture (Dext) feed the accounts automatically, and your dedicated chartered accountant answers in English within 24 working hours.
What changes when you are abroad is not the compliance, it is the coordination. The same seven blocks still apply: bookkeeping, the president payroll slip, VAT, the 2065 tax return, the annual accounts, the salary-versus-dividends review and local taxes such as the CFE. Two points deserve early attention:
- where you are tax-resident shapes how your salary and dividends are ultimately taxed, so the compensation review should be run before, not after, the first payment;
- a non-resident president still needs a clean French banking and document flow from day one to keep the file audit-ready.

Sector Ecosystem
SASU is widely used by solo founders, freelancers and consultants who want a corporate structure with digital operations. Online accounting firms attract them with speed and automation, but the real value comes from advice on compensation, VAT, expenses and the digital workflow itself.

FAQ
Frequently Asked Questions
Is an online accounting firm enough for a SASU?
Yes, if it does more than data entry. A SASU also needs advice on founder compensation, VAT, expenses, annual decisions and sometimes payroll. Digital tools should simplify the work, not replace the support.
Can I keep a SASU without paying myself at the beginning?
Yes, but the decision should be reviewed against cash, social protection and your personal-income needs. Scenario modeling helps avoid locking yourself into a weak compensation strategy.
Which tools should be connected first?
Usually the bank, the invoicing tool, document collection and expense tracking. Depending on the business, payroll or approval workflows may also matter. The key is to keep the process simple and controlled.
When does payroll become necessary in a SASU?
As soon as the president is paid as an assimilated employee or the company hires staff. It should be prepared early so cash impact and compliance deadlines are understood.
Can a SASU founder combine ARE unemployment benefits with their company?
Yes. As long as no director salary is taken, the SASU founder can keep 100% of their ARE benefits while invoicing through the company. Profits are retained in the SASU and distributed as dividends after the ARE period. This is one of the most powerful early-stage strategies for new founders after a rupture conventionnelle.
How does the shareholder current account work in a SASU?
The founder can lend cash to the company (and earn deductible interest at the official rate) or draw cash from it (subject to repayment or requalification as dividends/salary). A negative current account is a major audit flag and can be treated as concealed remuneration. We track the current account monthly to prevent drift.
What is the impact of the 2026 e-invoicing reform on a SASU?
From September 2026, every VAT-registered SASU must be able to receive e-invoices via an approved platform (PDP — Plateforme de Dématérialisation Partenaire). The obligation to issue e-invoices follows progressively. We set up the right PDP integration (Pennylane, Sage, QuadraFact) and train the founder before the obligation kicks in.
When should a SASU move to a multi-shareholder SAS?
When the founder wants to bring in a co-shareholder (partner, investor, key employee), or when the business needs equity-style fundraising. The transformation is straightforward: a simple shareholder decision turns the SASU into a SAS. The accounting and tax treatment stay similar, but governance becomes formal — board decisions, shareholders' agreement, possibly stock-option plans.
