Answers Before You Entrust Your Books
Everything Philippine entrepreneurs, freelancers, and licensed CPAs want to verify before switching to kontadurya.io.
Do I need an accounting background to operate kontadurya.io? +
None whatsoever. Kontadurya replaces complicated accounting terminology with intuitive entry sheets. The double-entry debits, credits, and tax allocations are computed autonomously under the hood.
Does it support both VAT and Non-VAT enterprises? +
Yes. During onboarding, specify your BIR registration status. Kontadurya presets your matrix to Percentage Tax (Non-VAT) or 12% Output/Input VAT. You can transition easily if your annual gross passes the VAT threshold.
Are exports officially acceptable for BIR audit & eFPS filing? +
Yes. Tax returns generate as valid eBIRForms XML files, and validation schedules (SLSP, SAWT, QAP) export as verified .DAT files formatted for the official BIR Relief Validation tools.
Does kontadurya.io replace my retained CPA? +
No, it empowers them. Instead of encoding shoe-boxes of receipts, your accountant accesses pristine, balanced trial balances and pre-compiled tax packs. You can invite your accountant with free dedicated access.
Is the Free plan genuinely free forever? +
100% yes. Free forever for up to 30 transactions every month with full double-entry bookkeeping, BIR compliance XML & DAT exports, and financial statements. There is no trial expiration and no credit card required.
