CollectFlows vs InvoiceShelf

CollectFlows manages accounts receivable and collections for businesses pursuing their own overdue B2B invoices. Excel or CSV imports can include invoice statements, daily collections, and branch targets, with automatic column-mapping detection. Due dates recalculate invoices into current, 1–30, 31–60, 61–90, and 90+ day buckets. The system records promised amounts and dates and flags broken promises after their dates pass. Teams can log calls, emails, and WhatsApp touchpoints with timestamps and attribution. An AI assistant answers questions about live receivables, gives daily briefings, accepts voice input, and replies in English or Arabic. Controls include branch and collector scoping, five roles, exportable audit logs, optional TOTP multi-factor authentication, and enterprise IP allowlisting. The browser interface adapts to phones and tablets; Android, iOS, API, and web platforms are listed. Growth costs 145 AED a month and Business 475 AED a month. A 14-day trial requires no credit card. CollectFlows does not contact debtors for customers.

InvoiceShelf is a free, open-source, self-hosted web application for invoices, estimates, payment tracking, and expense management. It supports branded documents, custom fields, tax rules, multiple currencies, and PDF templates. Recurring invoices can be generated for retainers, subscriptions, and repeat customers, while reports cover sales, taxes, overdue balances, and profit. Customers can view invoices, estimates, and payments in a private portal without creating a separate account. Users can record partial and full payments; the homepage lists Stripe checkout for online card payments. The application also supports payment reminders, remote file storage through listed drivers such as Dropbox, Amazon S3, and DigitalOcean Spaces, and backups from its interface. Backups can include everything, only the database, or only files. It advertises a REST API and module system, while webhooks are marked as coming soon. Hosting requires PHP 8.3 or 8.4, Nginx or Apache, and a supported database. The free plan is listed as free and includes unlimited invoices and customers.
