Frequently Asked Questions
What is 3-way matching in accounts payable and why does it matter?
3-way matching compares three documents — the purchase order (what you ordered), the goods receipt (what you received), and the invoice (what you're being charged). This prevents overpayment, catches billing errors, and detects fraud. Acua automates this at the line-item level with configurable tolerance thresholds.
What document types can I upload for matching?
You can upload invoices, purchase orders, and goods receipts as PDF, PNG, JPG, JPEG, WebP, or HEIC files. Each document type has specialized OCR extraction — invoices include VAT and withholding tax fields, POs include receiving status tracking, and GRs include quantity verification.
How does duplicate invoice detection work?
Acua uses two layers of detection: SHA-256 file hashing catches identical files, and canonical key matching (company + vendor Tax ID + normalized invoice number) catches invoices that are logically the same even if the files differ. Detected duplicates are classified as exact duplicates, version conflicts, or suspicious matches — each with clear resolution options.
Can I customize the invoice form fields?
Yes. You can add up to 20 custom fields per organization, choosing from 13 field types including text, number, date, single/multi-select, and master data lookups. Each field supports conditional logic — show or hide based on amount, vendor, PO linkage, or other custom field values. A live preview panel lets you see changes in real time.
What payment methods are supported?
Acua prepares approved invoices with clean vendor, tax, and coding data so your finance team can continue payment and accounting work in the right downstream systems without duplicate entry.
How does Acua handle Thai tax invoices?
Acua natively supports Thai tax invoices (ใบกำกับภาษี) with VAT at 7%, withholding tax rates from 1% to 15%, PP.36 forms, 13-digit Tax ID validation, branch code extraction, and Buddhist Era date conversion. Thai-language OCR accurately reads Thai numerals and addresses.
