Type a single sentence, something like 'Invoice to Acme Inc for $1,500 for website redesign, due in 30 days,' and Aviy turns it into a formatted invoice within seconds. Six kinds of billing paperwork can be produced this way, from invoices and estimates to quotes, credit notes, receipts, and purchase orders, working from a plain-language description instead of a blank form. According to the site, it's free to start, with no credit card required and every core feature available on that free tier. Aviy isn't bookkeeping or accounting software, and it doesn't function as a system for tracking client relationships or an entire invoicing operation; its scope stops at generating and sending one billing document at a time.
Describing what's owed, to whom, and by when is all the input required — the AI reads that intent and drafts the document instead of requiring a form-by-form setup. From there, customization options let you pick from multiple templates, adjust colors, add a logo and signature, and set tax rates and discounts before sending. Once a document is ready, it can be exported and shared; on higher tiers, clients can also pay directly from the invoice link after Aviy is connected to Stripe or PayPal, with payments tracked automatically in the dashboard. An approved estimate can also be converted into an invoice with one click, which matters for anyone who quotes a job before starting it and then has to bill for that same work without retyping the details.
Freelancers, consultants, and small agencies fit the most obvious use case, since project work tends to generate exactly this string of documents: a quote or estimate before work starts, an invoice once it's delivered, and either a receipt confirming payment or a credit note if something needs correcting afterward. Small businesses that don't need a dedicated system for managing client relationships can run that whole sequence inside one tool instead of switching apps for each document. Where the fit gets thinner is for anyone whose process depends on a fuller proposal or client-management workflow, such as tracking leads or building multi-stage proposals, since neither has been confirmed on the site as something Aviy handles. For occasional billing tied to a handful of clients, the six-document set covers most of a project's paper trail without extra setup.
Four named tiers gate different amounts of capability rather than just different volumes. Unlimited document creation is available from the entry tier, though only four documents can stay saved on the dashboard at a time. Removing the Aviy logo, adding client management, and lifting that four-document cap is what the next tier up unlocks. Online payment collection through Stripe, PayPal, or direct bank deposit becomes available a level above that, along with automatic payment reminders and room for up to five team members. At the top sits unlimited team members, no usage limits, and priority support. Anyone starting on the entry tier should plan around the four-document save cap before assuming it covers ongoing use; current pricing for each tier is worth checking directly on Aviy's own site.
The site states that all data is encrypted in transit and at rest, and that it uses industry-standard security practices and does not share data with third parties. Beyond that single statement, the site does not list any compliance certifications, such as SOC 2, GDPR, or PCI, to back up those security practices.
No source confirms accounting, bookkeeping, tax-filing, or expense-tracking capability for Aviy. Its confirmed scope covers generating and sending six billing document types (invoices, estimates, quotes, credit notes, receipts, and purchase orders), which makes it a document generator rather than a system of record for a business's finances.
As of this review, the /docs URL listed among Aviy's official sources returns a 404, so there's no public technical documentation confirming a developer API. The site does state that payments run through Stripe or PayPal and that documents can be sent via WhatsApp and Telegram, but nothing describes those as an open, documented integration for outside tools.
The entry tier allows unlimited document creation but caps the number of documents saved to the dashboard at four at a time — anyone expecting ongoing use beyond a handful of documents should plan on upgrading past that tier rather than assuming the free plan covers a full project history.
