Built by someone who closes the books.
RecStack was created by a controller who spent years building reconciliation templates, writing complex Excel formulas, and debugging balance sheet variances at 11 PM on close night. I built this because I was tired of rebuilding the same rollforward schedules every month, tired of tracking down formula errors, and tired of explaining why "AI-powered accounting" solutions made black-box decisions I couldn't defend to auditors.
This tool follows one principle: automation should make accounting more rigorous, not less explainable. Every reconciling item RecStack identifies can be traced back to a specific transaction or rule. No magic, no guessing — just the kind of deterministic logic that passes audit review.
