Connectbooks founder bio

Nachman Leiser is the CEO and founder of Connectbooks and Bottom Line Management. For over 10 years, he’s been an entrepreneur, financial analyst and profit gamechanger – usually all 3 at once.

After working as CFO in several businesses, growing their revenue by double-digit percentages and more, he founded his own ecommerce bookkeeping & accounting firm that specializes in uncovering ways to reduce cost, eliminate losses and scale profits. He helped online sellers in the red become profitable within a year and exceed the million dollar mark in net profits.

He developed an industry game-changing app, Connectbooks, that partners with Quickbooks and online marketplaces like Amazon, Shopify, Walmart and more. Today, Connectbooks helps hundreds of sellers reconcile every transaction in Connectbooks in a click, and

see itemized & bottom line profit and inventory updates as they happen.

Nachman has been regularly recognized as a pioneer and innovator, changing the role accounting traditionally played for ecommerce sellers, and creating systems that double, triple or even 10x profit margins for his clients.

He has a masters in Science, with a major in accounting from FDU.
