If upgrading requires contacting sales, you're leaving revenue on the table.
Sales-assisted upgrades cap your expansion revenue potential. The highest-leverage self-serve improvement most B2B SaaS products can make is enabling plan upgrades and add-on purchases without involving the sales team. We build the in-app upgrade flows, Stripe plan change handling, and feature unlock infrastructure.
Subscription upgrades that require contacting sales or support — creating friction in the upgrade path and limiting expansion MRR growth
Expansion MRR — revenue growth from existing customers upgrading or purchasing add-ons — is the highest-margin revenue a SaaS business generates. No sales cost, no acquisition cost, no onboarding cost. The customer is already sold on the product.
Most SaaS products on early billing implementations collect expansion MRR inefficiently: the customer decides they want to upgrade, they contact sales or support, someone processes the upgrade manually, and the feature access is updated. Each step introduces delay and drop-off: some percentage of customers who wanted to upgrade don't complete the process because the friction is too high.
The alternative: the customer hits a feature gate in the product, sees a clear upgrade prompt with the plan that includes the feature, clicks upgrade, confirms with their stored payment method, and immediately gets access. No email, no Intercom message, no sales conversation required.
The implementation requires:
- Stripe plan change handling via the Stripe API — upgrading a subscription mid-cycle with correct proration calculation.
- Webhook handling — the
customer.subscription.updatedwebhook updating the local subscription record and feature gates. - Feature gate checking — every premium feature checking the user's current plan before rendering.
- Upgrade prompt placement — upgrade prompts shown contextually when a user hits a feature gate, not only in the billing settings.
Self-serve in-app upgrade flows with Stripe plan changes, prorated billing, immediate feature unlock, and the analytics to see where in the funnel users upgrade
In-app upgrade flow
Upgrade prompt with plan comparison at the point of feature gate contact. Checkout via Stripe Billing portal or inline card confirmation.
Stripe plan change handling
Mid-cycle plan changes with correct Stripe proration. Immediate feature access on successful plan change. Webhook handler for the `customer.subscription.updated` event.
Feature gate system
Centralized feature flag system tied to the Stripe subscription plan. Every premium feature gated with clear upgrade prompt when accessed on a lower tier.
Usage-based upsell triggers
If the product has usage limits (API calls, seats, storage), in-app notifications when the user approaches their limit with a clear upgrade path before they hit the wall.
Upgrade analytics
Funnel analysis of upgrade path: feature gate contacts → upgrade prompt views → upgrade completions. Identifies where the upgrade funnel drops off.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Self-serve upgrade infrastructure scope is defined by the existing billing model and feature set. Fixed price after the billing audit.
Questions, answered.
If the feature differentiation between plans isn't well-defined, defining it is the first step before building the upgrade infrastructure. This is a product decision (which features are worth paying for) that drives the technical implementation.
Stripe supports both subscription plan changes and one-time charges or add-on subscriptions. Add-on purchases (e.g., "additional 10 seats" or "export credits") can be implemented alongside the plan upgrade flow.
Feature gate system + upgrade flows: from $14k. Full upgrade infrastructure with analytics: from $22k. Fixed-price.
