We watch your contracts. You run your business.
Too many signed agreements, and nobody paying attention. summie® keeps track of them, warns you before every deadline, and lets you know if you are overpaying.
CONTRACT INTELLIGENCE
Contract management that also audits your invoices.
As an entrepreneur, you sign contract after contract. Purchasing, maintenance, cleaning, suppliers. Before you know it, one of them is tacitly renewed for another year, a price creeps up, or you pay an invoice that is incorrect. Nobody notices.
That is what we are here for. summie keeps an eye on your contracts, so you don't have to.

TEAM
Meet the founders
We are a brother-sister team with a strong entrepreneurial mindset. Nathalie worked in hospitality for years before moving into finance. She knows both sides: the fast-paced operational side of hospitality and the administrative processes behind it. Martijn worked as a technical consultant at the Dutch Tax Authority and at various ERP companies, and saw up close where systems get stuck. And negotiating is in his blood: he gets a better deal out of every contract. Together, we combine domain knowledge, technology, and hands-on experience.
