Seven tools that actually run.
The pages under /flow/v1, /flow/v2 and /flow/v3 are design studies: the figures on them are invented samples. These seven are the real thing. Each one takes a file you already have, reads it inside your own browser, and gives you numbers plus a file to download.
Where they run. The working build is a separate private test site, not part of aevyx.in, so it can be tried on real books before anything is published. If you would like the link, email us or send a DM. Running it yourself from the repository: node serve.mjs inside site-preview/aevyx-tools, then http://localhost:4800/. The one tool that already runs here on the site is the payment cost check.
Bill scan
A photo or PDF of a supplier bill becomes a purchase-register row: party, GSTIN, invoice number, date, line items, taxable value, the GST split and the total. The GSTIN checksum is verified, the totals are recomputed from the parts, and anything misread can be corrected before export. Near-duplicate bills in the same batch are flagged.

A statement PDF or CSV becomes clean transactions, each with a suggested ledger read from its narration, then an import-ready Tally XML file or a CSV. Debits and credits balance per voucher, the running balance is checked row by row, and a PDF password you type is never stored.

Your purchase register against the GSTR-2B you downloaded. Matched lines collapse; what is left is what is missing from 2B, missing from your books, or different in value, each with the reason: an invoice number written two ways, a rounding gap, a wrong GSTIN, a line the vendor never filed. Tolerance is yours to set. Accept, reject and pending stay decisions you take on the portal.

The same files, all at once, through every check: bills paid twice, vendors who have not filed, credit that stops being claimable on 30 November, late fees and interest on returns filed after the due date, refunds with no credit note. Rupees at risk per check, with the method on the row and the figures labelled as estimates.

Every micro or small supplier bill gets its 15 or 45-day clock, a pay-by date one day inside the limit, the days left, and what Sec 43B(h) does to the deduction if it slips. Medium enterprises are left out of the rule, and a supplier you have not classified is shown as unknown rather than assumed either way.

Thirteen weeks of projected cash from your own transactions, with the week the balance dips lowest named and dated, recurring outflows found in the history, DSO, inventory days, DPO, the cash conversion cycle and an indicative health score. Move one receipt or one payment by a week and the strip redraws.

Type the job the way you would message it, or photograph a handwritten slip, and get a tax invoice: item rows, the taxable value, CGST and SGST within a state or IGST across them, the Sec 170 round-off, the total, the amount in words and a PDF. It drafts the invoice for you to issue; it does not produce an IRN, so an e-invoice still comes from the portal.
In: typed lines or a slip photo · Out: a GST invoice PDFThe text-to-invoice and slip reelsAll seven read the files you choose inside your own browser. Nothing is uploaded, no account is involved and no server sees your books. Each one computes, flags and drafts; you or your CA review and file. None of them logs in to the GST portal or asks for a portal password.
