Bookkeeping for London's steady, professional economy.

Numinor keeps the books for London businesses, from medical and dental practices to the insurance, professional services, and established small businesses that anchor the city. Our office is in Waterloo and we serve London clients remotely, so you get a responsive team and clean monthly numbers without a downtown office on the bill.

London has a steady, professional economy. Healthcare is a major employer, the insurance sector runs deep, and the University of Western Ontario feeds a base of professional and knowledge businesses. These are not flashy, fast-burn startups; they are established practices and firms that want their books accurate, their tax handled, and their accountant reachable. That is exactly how we work. Many of these are professional corporations, where keeping the corporation and the owner cleanly separated matters for both compliance and tax.

To be clear about what we are: our office is in Waterloo and London is served remotely. For an established practice or firm, that works well. Cloud books, a reachable team, and no commute for a routine review.

Local notes that affect your books

Professional corporations and healthcare exemptions.

London businesses collect HST, not separate GST and PST, though many healthcare services are exempt, which makes correct treatment important. Professional corporations for doctors, dentists, and other professionals carry specific bookkeeping and tax considerations. With employees you handle WSIB and, above the threshold, Ontario's Employer Health Tax. We keep all of it current.
