IT SolversAn AI-first IT problem solver
IT Solvers is an IT company that works AI-first, from analysis to testing, and handles software and app development, IT asset supply, and computer, server, and NAS setup. Below are the tools and MVPs we've built AI-first: designed by people who know the work, then developed and tested with AI. Calculator amounts are in U.S. dollars ($), and the guides follow K-IFRS (Korean accounting standards), not U.S. GAAP.
Guides and terminology
Web UI Glossary ↗
99 web UI terms such as hero sections, modals, and toasts, with live examples you can try and copy-ready code.
Lease revenue recognition guide ↗
See how a lessor recognizes revenue and books journal entries for finance and operating leases, with a 36-month example and a vehicle-sale entry. Amounts are in U.S. dollars.
Lease terminology ↗
Residual value, lease payments, the implicit rate, initial direct costs, and more, explained in plain English.
Lease business overview ↗
A short intro to what counts as a lease, lessee accounting, how lessors classify leases, and the common lease types under K-IFRS 1116.
Calculators
Lease cash-flow IRR calculator ↗
Enter the monthly receipts and when insurance and vehicle tax are paid to get an annualized cash-flow IRR.
Find a lease payment from a target IRR ↗
Start from a target cash-flow IRR and work backward to the base monthly lease payment with a bisection search.
Lease payment calculator ↗
Estimate a monthly payment from the vehicle price, term, annual rate, and residual value at the end of the term.
MVP (Minimum Viable Product)
E-Contract ↗
E-signatures without a subscription, for people who'd rather not leave their contracts on someone else's platform. Install it on your own server to keep your contracts for good. The other party just signs on their phone from a single link.
Get a Lease Estimate (in progress) ↗
Build a lease estimate from the vehicle, term, and interest rate. It's still in development and only available in Korean.
Accounting for Developers ↗
A basic accounting tool that helps you get comfortable with account titles through quizzes. The tool itself is in Korean only.
Important: These tools are for illustration and learning only. They aren't an estimate, accounting opinion, or tax advice, and they don't replace the actual contract or the applicable standards. The lease guides are based on K-IFRS 1116 and may differ from U.S. GAAP and U.S. tax rules.
