Recurring billing that holds up under fifty sets of state rules.

Codeeo offers subscription billing software development USA businesses use to sell plans, renew them on schedule, recover failed payments and collect the right sales tax in every state where they have nexus. We build the billing engine, the customer portal, the mobile account screens and the finance dashboard as one system, connected to your payment processor, your CRM and your general ledger. You get a platform that charges correctly, cancels cleanly and gives your finance team numbers they can close the month on.

American subscription rules sit at three levels at once: federal consumer protection, state auto-renewal and tax law, and card network rules written by Visa and Mastercard. A billing system has to satisfy all three on every single renewal, which is why we plan compliance as product logic rather than a checklist added before launch.

Built for
SaaS companies, membership brands, media publishers, box retailers and service businesses selling recurring plans to customers in many states.
Typical timeline
Timing is settled in discovery once migration volume, tax scope and integrations are known, and the delivery plan is written down before design begins.
What you own
The source code, the billing database, every customer and invoice record, and the processor and tax accounts, all registered to your company.

Inside the platform

What a national subscription business needs from its billing system.

Off the shelf billing tools cover the common case well. They start to strain when your pricing mixes seats, usage and annual commitments, when sales negotiates custom terms, or when you sell to consumers in states with their own renewal statutes. That is usually the point where a company asks for custom subscription billing software development USA finance and product teams can shape themselves. Sometimes the right answer is a custom layer on top of Stripe Billing, Chargebee or Recurly; sometimes it is a billing engine of your own that talks to a processor directly. We make that call with you in discovery, based on your plan structure, transaction volume and how much control your finance team wants over revenue logic. Whatever the architecture, the parts below are where the real work sits. Our team of 80+ across Dubai, Riyadh and Karachi works remotely with American clients, and discovery, design reviews and sprint demos all run by video call.

Explain your project
  • Plan catalog and pricing models

    Flat plans, per seat pricing, tiered and volume usage, hybrid base plus overage, annual prepay with monthly true ups and negotiated enterprise terms, all defined in an admin catalog rather than hard coded. Product managers can launch a new price point or grandfather existing customers on an old one without a developer touching the release. Every price change is versioned, so an invoice from last year can always be explained against the price that applied then.

    Pricing experiments ship in days of admin work, not a code release.

  • Proration and plan changes

    Upgrades, downgrades, seat additions and mid-cycle switches between monthly and annual terms calculate credits and charges to the day, with a preview the customer sees before confirming. Rules for when a downgrade takes effect, immediately or at renewal, are configurable per plan.

    Customers see exactly what a change will cost before they accept it.

  • Usage metering

    An event pipeline that ingests API calls, minutes, gigabytes, messages or any unit you bill on, deduplicates retries, applies rating rules and rolls usage into the invoice at period close. Customers watch a live meter in the portal so overage never arrives as a surprise.

    Usage bills that customers can trace back to their own activity.

  • Dunning and payment recovery

    Retry schedules tuned by decline code, card updater services from the networks, network tokens where your processor supports them, and reminder emails and in-app banners that send the customer to a one-tap card update page. Grace periods and service limits on past due accounts follow rules you set.

    Fewer customers lost to an expired card they forgot to replace.

  • Multistate sales tax

    Since South Dakota v. Wayfair in 2018, states can require remote sellers to collect tax once they pass an economic nexus threshold. Whether a digital subscription is taxable at all differs by state. We connect a tax engine such as Avalara or Stripe Tax, track nexus by state and store the tax decision on every invoice line.

    Tax collected where you owe it, with an audit trail for every charge.

  • Auto-renewal compliance

    Clear disclosure of renewal terms beside the checkout button, separate consent capture with a stored record, confirmation emails, renewal and price change reminders, and online cancellation available through the same channel the customer used to sign up. Rules are applied by the customer's state, so stricter requirements can switch on where they apply.

    Renewal flows built to the strictest state rules you sell into.

  • Customer portal and mobile account screens

    Customers view plans, change seats, download invoices, update cards and cancel from the web or from your iOS and Android app. Where in-app purchase rules apply on Apple and Google stores, we plan the purchase flow with you so app review and billing stay consistent.

    Most billing questions answered without opening a support ticket.

  • Revenue recognition and ledger sync

    Invoices, payments, refunds and credit notes post to QuickBooks, NetSuite or Xero, and deferred revenue schedules follow ASC 606 logic your controller agrees in advance. Monthly recurring revenue, churn and expansion figures come from the same records the ledger uses.

    Finance closes the month from billing data, not spreadsheets.

  • Invoicing, ACH and net terms

    Larger American buyers rarely pay by card. The platform issues invoices with purchase order numbers and net payment terms, accepts ACH debits and credits, and records the recurring debit authorization that Nacha rules expect before you pull funds from a customer's bank account. Payments received by wire or check are matched to open invoices so collections staff see a true aging report rather than a guess.

    Enterprise customers pay the way their accounts payable teams require.

  • Card data security

    Card entry runs through your processor's hosted fields or payment page, so raw card numbers never reach your servers. That design keeps your PCI DSS scope small, usually to a self assessment questionnaire rather than a full on-site assessment, and we document the data flows your assessor will ask about.

    A smaller compliance burden and no stored card numbers to protect.

Who we build for

Four kinds of American subscription business we work with.

The subscription model looks similar from the outside, but billing needs differ sharply between a B2B software firm with annual contracts and a consumer brand renewing monthly boxes in every state. The starting point decides which compliance rules dominate, which processor features matter and how much of the platform has to be custom. Most teams that come to us looking for subscription billing software developers in the USA arrive in one of these four situations.

01

B2B SaaS outgrowing its first billing setup

You launched on a hosted checkout and a simple plan list. Now sales closes deals with ramped pricing, committed usage and custom invoice terms, and finance reconciles by hand every month. We build a contract aware billing layer, connect it to your CRM so a signed quote becomes a live subscription automatically, and keep self serve customers on the same engine.

Usually a custom layer over an existing processor.

02

Consumer subscriptions sold in many states

Meal kits, beauty boxes, streaming, fitness and learning apps renew small amounts for very large customer bases, which puts state auto-renewal statutes and FTC enforcement front and center. The work focuses on disclosure, consent records, reminders and an online cancel path that state laws such as California's expect, plus retention offers that stay on the right side of those laws.

Compliance logic matters as much as payment logic here.

03

Membership and service plans

Gyms, clinics, home maintenance plans, coworking spaces and clubs bill members on a cycle but deliver in person. They need freezes, family add ons, location based pricing and staff tools at the front desk, alongside a member app. We design both sides together so the desk and the app never disagree about a member's status. Members who move between locations in different states keep one account, with tax and renewal rules following the location that bills them.

04

Companies leaving a legacy billing system

Moving thousands of live subscriptions is risky: renewal dates, stored payment methods and price histories must arrive intact. We plan token migration with both processors, run parallel billing on a sample of accounts, compare every invoice and switch over only when the totals match.

Card tokens move processor to processor, never through our hands.

How a billing platform goes from scope to first renewal.

  1. 01Pricing and contract mappingEvery plan, discount, trial, contract term and edge case written down, including the awkward ones finance currently handles by hand, so the data model reflects how you actually sell.
  2. 02Compliance and tax scopingStates where you have nexus, states with auto-renewal statutes that affect your customers, and your PCI DSS scope, reviewed with your counsel and tax adviser before architecture is fixed.
  3. 03Architecture and processor choiceBuild on a billing provider or own the engine, which processor, which tax engine, and how events flow to the ledger and the CRM, agreed and documented.
  4. 04Billing engine and portal buildCatalog, proration, metering, invoicing, dunning and the customer portal built in short sprints, each demonstrated by video call against real pricing scenarios.
  5. 05Parallel runs and migrationInvoices from the new system compared line by line against the old one on live data, tokens migrated, and cutover timed away from your heaviest renewal days.
  6. 06Operating after go liveRecovery rates, failed webhooks, tax exceptions and support tickets tracked, with a release plan for the next pricing models your team wants to test.

Technology

What we build this with.

Usually a TypeScript or Python service layer, PostgreSQL for billing records, an event queue for usage data, and React or Next.js for the portal, with React Native or native code for mobile. Processor and tax engine choices follow your volumes and your existing contracts. Hosting runs on AWS, Azure or Google Cloud in a US region, inside an account your company owns, with backups and access logs your auditors can review.

What US subscription businesses ask us first.

Pricing complexity, migration volume, integrations and compliance scope.

A handful of flat plans on one processor is a far smaller build than hybrid usage pricing with enterprise contracts, a CRM link and an ERP sync. Migrating live subscriptions adds testing time, and selling to consumers in strict auto-renewal states adds consent, reminder and cancellation work. We price after discovery, once those factors are known, and the proposal shows how each one affects the estimate.
