We redesigned a SaaS company's subscription and billing workflows as separate services for plans, payments, invoices, entitlements and notifications. Processes that affect revenue are now easier to manage and to recover when something fails.

Overview
The challenge
Subscription changes, payments, invoices, account access and notifications had all grown up inside the same backend code.
When one step failed, such as a payment webhook, a customer could end up with the wrong access, and someone had to correct it by hand. The company needed each part separated and a reliable way to recover.
One failed event could leave a customer's account showing the wrong status.
Any change to billing logic also touched account and product-access code.
Support and engineering teams had to investigate failed subscription states one by one.
The solution
We gave plans, subscriptions, payments, invoices, entitlements and notifications a service each, so every part of billing has one clear job.
Payment and subscription events trigger updates in other services, rather than forcing every service into one large transaction.
Retries, safe repeat processing, logs and a live status view make failed events much easier to recover.
Before and after
Before
Mixed together
Payments and account access shared tightly linked code.
After
Focused services
Each revenue task sits in its own service.
Before
Manual fixes
Each failed webhook had to be investigated and corrected.
After
Recoverable
Retries and event tracking make failures far easier to resolve.
Before
High risk
A billing change could break unrelated account workflows.
After
Changed independently
Billing services can be improved with less effect elsewhere.
Key features
Subscriptions, payments, invoices and access rules each live in their own service.
Business impact
Clearer billing logic
Webhooks and billing events are processed with checks that stop duplicates and catch missed updates.
Business impact
More reliable revenue workflows
Teams see failed events, retries and each customer's current state in one live view.
Business impact
Faster issue resolution
Results
More Reliable Subscription Updates
Billing events now have clear recovery paths when something fails.

Faster delivery
With sign-in, events, monitoring and notifications already in place, the team could focus on the company's own billing rules.
Gave every billing service the same sign-in and role checks from the first release.
Provided the event and webhook handling that passes payment updates between services.
Supplied the retries, logs and alerts behind the live billing status view.
Sent customers payment and subscription notices from one service, apart from the billing logic.
Trust and control
Staff see only the billing information and actions their role allows.
Access controlledPayments, invoices and entitlements stay linked to the same customer record instead of being scattered across tools.
ConnectedRetries, duplicate checks and clear error handling keep revenue workflows dependable.
ReliableThe client owns the billing services, workflows, integrations and source code created for the project.
100% ownedSubscriptions, payments, invoices, account access and notifications all lived in the same backend logic. When one step failed, such as a payment webhook, a customer's account could end up in the wrong state. Support and engineering then had to investigate and fix it by hand, and billing changes risked breaking product access.
We split billing into separate services for plans, subscriptions, payments, invoices, entitlements and notifications. Payment and subscription events trigger updates in other services instead of one large transaction. Retries and safe repeat processing handle failed or duplicate webhooks, and a live status view shows failed events and each customer's state.
Support staff can now see payment and subscription state, failed events and retries in one live view, instead of asking engineers to investigate. Failed events retry automatically, so fewer accounts need manual fixes. Engineers can also change billing logic without touching the code that controls account access.
If a failed payment event can leave customers with the wrong access, we can help you separate your billing logic and add clear recovery paths.
