Oaatz Cosult Ltd helps businesses clean up their accounting, migrate off spreadsheets, and build the websites, web apps and automation that keep everything running. Led by Temidayo Olowoyo — 15 years in accounting, backed by a full development stack.
Oaatz Cosult Ltd was built on a simple observation: businesses hire one specialist to fix their accounting and another to build their systems, and pay for the gap between them. We close that gap.
Fifteen years of hands-on accounting and systems training — Sage, QuickBooks and Zoho expertise, spreadsheet-to-system migrations, and account department re-engineering across logistics, retail, travel, telecom and banking — sit alongside a full web development practice: websites, web apps, POS systems and accounting automation, built in PHP, JavaScript and SQL and deployed on Vercel and cPanel.
One point of contact. No translation gap between the accountant and the developer. Systems handed over clean, with your team trained to run them.

15 years in accounting systems — Sage, QuickBooks & Zoho — paired with a full stack of PHP, JavaScript, PostgreSQL, GitHub and Vercel. Works with businesses anywhere in the world.
Every project draws on both — the accounting knowledge that finds the real problem, and the technical build that solves it for good.
Sage, QuickBooks or Zoho, configured properly or untangled if it's already a mess.
Move off spreadsheets without losing history, formulas, or your sanity.
Workflows redesigned to solve the root problem, not just patch the symptom.
Hands-on training tailored to your industry, so the system stays clean after we leave.
POS systems wired into your accounting backend — no re-entry of sales data.
Business websites and web apps built end to end, deployed on Vercel and GitHub.
Custom automation tools, including systems built for accountants working solo.
Monthly accounting & bookkeeping support only. Website builds, POS implementation and automation projects are quoted separately per project.
