Recurring Invoice Management
Set flexible billing intervals for repeat clients, and the platform automatically generates and sends invoices on schedule, supporting subscription billing transformation for long-term payment cycles.

A multi-tenant cloud invoicing software platform that helps small and mid-sized B2B businesses automate one-time and recurring invoices, collect signed agreements before payment, and track FluidPay transactions in real time, built on Azure serverless architecture.

Small and mid-sized B2B businesses were struggling with manual invoicing. Payment statuses lagged, due and overdue reminders were sent by hand, and agreements were signed outside the payment process, slowing collections and increasing errors and disputes. Ditstek built a B2B invoicing software platform that brings one-time and recurring invoices, customer management, payment agreements, and billing schedules into one invoice management system. As an Azure serverless transformation of the billing process, it delivers high scalability, lower infrastructure costs, and minimal maintenance, with each business working from its own secure subdomain.
Addressing the critical gaps in automation, integration, and payment workflows to deliver a secure, real-time, and user-centric recurring invoice software platform for modern B2B businesses.
Invoice statuses depended on constant polling, so businesses could not see transactions instantly, which weakened financial planning and slowed down everyday billing and finance operations.
Sync delays between the platform and the FluidPay payment API caused mismatches in customer records, payments, and invoice statuses, making it hard to trust billing data.
Without automated reminders for due or overdue invoices, finance teams chased every payment by hand, and delayed payments made cash flow inconsistent from one month to the next.
Sending customers to external e-signature platforms interrupted the payment journey, adding extra steps between invoice and payment and reducing the number of customers who completed both.
There was no way to generate agreements automatically based on payment preferences, so manual contract handling slowed customer onboarding and created extra work for every new account.
Handling contracts manually and outside the payment flow increased the risk of errors, disputes, and non-compliance, with no reliable link between signed agreements and invoices.
Ditstek delivered a billing platform modernization for B2B businesses, combining Azure serverless architecture, real-time payment sync, automated reminders, and in-platform agreement signing to replace manual invoicing with end-to-end billing workflow automation.
FluidPay webhooks replaced constant polling, so invoice statuses update the moment a payment event happens and businesses can track every transaction in real time from one dashboard.
Bi-directional API synchronization between the platform and FluidPay keeps customer, payment, and invoice data consistent across both systems, removing the mismatches that previously caused confusion.
Azure Functions Timer Triggers send daily due and overdue invoice reminders by email and SMS through SendGrid and Twilio, keeping follow-ups consistent without manual effort.
Businesses build dynamic agreements based on payment type using a drag-and-drop builder, so the right contract is generated automatically for every customer and billing arrangement.
A custom e-signature module lets customers sign the agreement first, then pay through an embedded FluidPay payment form, completing the whole journey without leaving the page.
Every signed agreement is stored securely and linked automatically to its invoice, giving businesses a clear, reliable record of what each customer agreed to before paying.
Built as recurring invoice software for small and mid-sized B2B businesses, the platform covers the full billing cycle, from customer setup and agreements to invoicing, payments, reminders, and real-time reporting across every tenant.
