About Us

DLI Business Services was built on a simple belief, that every small business owner deserves accurate books and someone who actually cares and explains what the numbers mean.

Why Choose Us

Meet Diana Irving

Diana founded DLI Business Services over 30 years ago with a clear goal: to give small business owners clean, accurate books they can actually rely on. She started by serving a handful of clients in Calgary and built the firm steadily, growing one referral at a time. From the beginning she focused on quality and consistency, making sure each client’s records were organized and correct. That steady approach led to a reputation for being thorough and approachable, and for being genuinely invested in her clients’ success. That reputation allowed the business to expand while keeping the original promise intact. Today Diana leads a team of four and still makes reliable, accurate financial records the top priority for small business owners.

The firm now serves clients across Canada and the US and offers bookkeeping, payroll, GST/HST filing, and year-end preparation. DLI Business Services has kept a deep specialization in working with real estate investors, Airbnb hosts, rental property owners, and trades businesses. The team applies the same careful attention to detail that defined the company’s early days, making sure transactions are recorded properly and financial information is dependable.
