InvoiceFlows

Visit invoiceflows.com

In short

Small and growing businesses still type invoice data into spreadsheets by hand. InvoiceFlows reads, organizes and manages every invoice, from upload to the accountant.

The problem

Every invoice means copying the same fields by hand: supplier, date, amounts, VAT. The work is slow, mistakes slip in, and at the end of each period the invoices still have to be gathered and sent to the accountant.

How it works

A PDF or a photo of an invoice is uploaded, and the AI reads the supplier, dates, amounts, VAT and description, ready to check and save. Income and expenses are sorted into categories as they arrive.

Every saved invoice updates a live dashboard with revenue, expenses and profit. Reports download as PDF or Excel, and a period's invoices go to the accountant in one click, filtered by type, date or category. Team members can be invited with their own permissions.

The outcome

InvoiceFlows is live at invoiceflows.com, with a free plan and paid plans that add storage, AI credits and users. Aplis AI built it end to end: the interface, AI extraction, analytics, sign-in and subscriptions.
