NERACIA POSITIONING · DONE BY PEOPLE, NOT SOFTWARE
Not accounting software you have to fill in yourself. Done directly by a human operator.
Many business owners already subscribe to accounting software or use spreadsheet templates, yet their reports still fall behind because no one has time to check receipts and reconcile bank statements. Neracia is a human-delivered service—not a self-service app.
Why business owners choose a human-operated service over a software subscription alone
Work Aspect
Self-Service Accounting Software (App Only)
Neracia (Human-Operated + Recorded Self-Check)
Who does the work each month?
You or your internal staff must spend time entering transactions, selecting chart-of-account codes, and matching bank statements inside the app yourself.
Carried out directly by a person (Neracia’s human operator). You supply bank statements and transaction documents; we organize, reconcile and prepare the reports.
When documents are missing or bank balances differ
Software simply adds up whatever was typed. If entries are duplicated, misclassified or missing evidence, charts still render as if everything were accurate.
A human operator checks supporting evidence line by line (recorded self-check), isolates unclear items into an open-action register, and reviews them with your contact.
Readiness for new tax rules (PP 20/2026 & Coretax VAT)
Software only provides form fields; you still have to interpret regulations yourself to check 0.5% Final Tax eligibility or Coretax invoice codes.
We prepare workpapers referenced to official rules (PP 20/2026, PMK 81/2024), track the 20th-of-month e-Faktur deadline, and organize review-ready materials for your authorization.
Relationship with tools you already use
Requires migrating into a specific app and paying recurring subscription fees even during busy months when nobody has time to input data.
No forced software migration. We can work from CSV/Excel exports of your existing tool or raw source documents, and hand over complete files that you own.
What about local tools and AI at Neracia?
We use deterministic calculations for numerical accuracy and use AI only in a limited way to help structure explanations—always with human review before handover, and without uploading confidential client documents to public AI services.
Guides, Schedules, Templates & Services in one connected ecosystem.
Every official regulatory guide, compliance calendar, document checklist, reconciliation workpaper, and business tax package is interconnected for seamless navigation.
2027 Final Tax & Eligibility Checker
PP 20/2026 rules, year-cap elimination for OP & PT Perorangan, corporate transition rules, and 13-case eligibility checker.
Official regulatory references for VAT compliance and DJP Coretax procedures.
All statutory deadlines, document requirements, and drafting mechanisms on this page are verified directly against official Republic of Indonesia legislation accessed via government portals (pajak.go.id, peraturan.go.id, and jdih.kemenkeu.go.id). Neracia acts as a draft preparer (Drafter role); electronic signing, payment, and return submission remain with the Taxpayer or authorized representative under PMK No. 44 of 2026.
