OPrisma

OPrisma is an accounting practice on Rue de l'Intérieur in Perwez, Walloon Brabant. The office brings together the two qualifications the ITAA distinguishes, certified accountant and certified tax adviser, and is registered under number 53.371.319. It reports more than fifteen years of experience in those fields.

The offering is presented in three numbered strands, which gives a clear reading of its scope. The first is accounting expertise, framed by the firm in terms of outcome rather than task: giving a clear view at every moment. The second is tax advice, with a twofold aim stated plainly, reducing both tax risk and the amount of tax. Distinguishing the two is right: aggressive optimisation can lower the tax while raising the risk, and that trade-off belongs to the informed business owner.

The third strand is financial management, aimed at optimising the company's financial position. That strand goes beyond accounting production and touches the structure of the balance sheet, working capital needs and financing, meaning the questions that decide whether a profitable business nonetheless has the cash it needs.

Digitalisation is put forward from the site's opening line, with an explicit purpose: giving access to clear and precise information at any time, so the owner can decide. That is the useful framing of the promise, linking the tool to the decision rather than presenting technology as a value in itself.

One geographic detail deserves attention: the firm states that it serves clients across both French- and Dutch-speaking Belgium. For an office based in Walloon Brabant, working on both sides of the language border implies mastering both procedural languages in tax matters, which remains uncommon in practices of this size and opens the door to companies whose activity crosses that border.

Working in both national languages implies more than translating documents. The language of tax procedure depends on the company's place of business, and it determines the language in which an audit is conducted, an objection is filed and a dispute is argued. A practice based in Walloon Brabant that says it also serves Flanders therefore commits to running a procedure in Dutch, not merely to answering an email. Few offices of this size do so, and it opens the door in practice to businesses whose activity crosses the language border.

The firm describes its team as dynamic and focused on tailored solutions for each client. The client base brings together self-employed professionals, small companies and companies being formed. For a business in Walloon Brabant or eastern Hainaut, combining both accreditations in one office, accounting and tax, avoids having to consult a second adviser as soon as the question turns technical.
