How three Avyth tools were built
These are Avyth's own products, rather than client projects. Each tackles a different task: processing a file, reconciling records, or calculating an answer with assumptions you can check. Read how they were built, or try them yourself.
Built by Avyth · File processing, and an interface that admits uncertainty
Split one merged invoice PDF into separate named files
Invoice Splitter
Accounting systems and scanners hand you one PDF containing dozens of invoices. Filing them means finding where each invoice starts, splitting there, and naming the result by invoice number — a job that is mechanical, slow, and easy to get subtly wrong.
Built by Avyth · Reconciling two record sets, and making exceptions reviewable
Find inventory losses with no matching reimbursement, before the window closes
FBA Gap Auditor
Amazon publishes inventory adjustments and reimbursements as separate reports. A seller who wants to know which losses were never reimbursed has to match them by hand — and each one has a filing window that quietly expires.
Built by Avyth · Calculation with assumptions the user can inspect
Plan a card payoff that survives the 0% promo expiring
Payoff Lab
Most payoff calculators treat a 0% intro card as free money forever. When the promotional rate ends the real schedule diverges sharply from what the calculator promised — usually at the moment the plan mattered most.
