Services · Ecommerce development · Billing software subscription sites
Codeeo offers subscription billing subscription website development USA software companies use to sell recurring billing, invoicing and payments products to customers in every state. We build the plan and pricing pages, sign-up and checkout, recurring charges, proration, dunning, invoices and the self-serve account area. The platform calculates tax by customer location after Wayfair, respects a patchwork of state privacy and renewal laws, and takes cards, wallets and ACH the way American businesses pay.
You sell billing software, so your own billing has to be beyond reproach. Our team of 80+ across Dubai, Riyadh and Karachi works with US clients remotely, running discovery, reviews and testing by video call, and is with every decision written down and shared with your staff, and is rated 4.7 from 23 Google reviews.

Core capabilities
Selling software across the United States means meeting rules that change at every state line. Since the Supreme Court's Wayfair decision in 2018, states can require remote sellers to collect sales tax once they pass an economic nexus threshold, and states disagree on whether SaaS is taxable at all. California, for one, begins taxing SaaS and prewritten software on 1 January 2027 under SB 122. A growing number of states now have comprehensive consumer privacy laws with different rights and thresholds. Auto-renewal laws differ too, and the federal click-to-cancel rule was vacated in 2025 while ROSCA still applies.
SaaS website development for a national vendor has to absorb all of that quietly, so a customer in Ohio and a customer in Washington both see a clean checkout and a correct invoice. These are the parts we build, chosen for that national picture rather than for any single city.
A tax engine such as Avalara, Vertex or Stripe Tax calculates tax by customer address, treats SaaS as taxable or exempt state by state, and applies local rates. Nexus tracking shows where you are approaching thresholds so your advisors can decide on registration. Exemption certificates are collected in the account area and stored against each customer.
Correct tax in every state you register in.
Plans, add-ons and usage tiers are defined once in the billing system and rendered on the pricing page, comparison table and checkout from that single source. Your team edits copy and layout in the CMS, while prices change in one place and flow everywhere, including existing quotes where you choose.
Pricing updates without a release.
Cards and Apple Pay or Google Pay through hosted fields that keep your site largely outside PCI DSS scope, plus ACH debit with bank verification for customers who prefer it, following Nacha rules for authorization wording. Larger accounts can be approved for invoice billing with wire or ACH remittance.
Every common US payment method on one checkout.
Customers upgrade, downgrade, add seats or switch to annual billing from the account area. The site previews the prorated charge or credit before they confirm, and your rules decide when reductions take effect. Mid-term additions co-term to the existing renewal date so customers keep one billing cycle.
Expansion happens without a sales call.
If you offer trials, you set the rules: length, card required or not, features included and what happens at the end. The site sends the reminder state laws expect before a trial converts to a paid plan, and records the terms the customer accepted.
Trials convert with disclosures already handled.
Clear renewal terms by the payment button, consent captured and stored, reminders configured per state, and cancellation online in the same channel the customer used to sign up. Rules are kept in configuration, so a change in California, New York or another state means editing a setting rather than rewriting checkout.
One checkout that adapts to state renewal laws.
Automatic retries, card updater services through your processor, ACH return handling, and short reminder emails to the billing contact. Grace periods and access changes follow your rules, and your revenue team sees a live list of accounts in recovery with the reason for each failure.
Involuntary churn is caught before it costs a customer.
A privacy notice that reflects your real data use, a single request route for access, correction, deletion and opt-out, recognition of the Global Privacy Control signal where states require it, and a log of every request. The process works for California, Texas, Virginia, Colorado and the other states with comprehensive laws.
One privacy process covering every state's rules.
Our billing integration services across the USA connect the site to Stripe Billing, Chargebee, Recurly or Maxio, your tax engine, Salesforce or HubSpot, and QuickBooks, NetSuite or Sage Intacct. Each connection has documented error handling and alerts, so a failed sync is noticed the same day.
Customer, invoice and revenue data agree everywhere.
Invoices show your legal entity, remit-to details, tax by jurisdiction and purchase order references. Credit notes handle refunds and downgrades, statements summarize open balances, and a W-9 is available to download for customers onboarding you as a vendor.
Accounts payable teams process your invoices first time.
Who this is for
Billing software companies across the country share one problem: their customers are spread over many states while their team sits in one. Subscription platform development for that situation starts from where your revenue comes from and where it will come from next. These are the four starting points we see most.
You started selling locally and now have customers in a dozen states. Your tax handling was built for one. We introduce a tax engine, map your product's taxability state by state with your advisors, set up exemption collection, and rework invoices so each customer sees the tax their state applies. Registration decisions stay with your accountants, and the site follows them. Customers in states that do not tax your product see no tax line at all, which avoids awkward refund requests later.
Tax readiness usually comes before new marketing spend.
Your customers are contractors, clinics, agencies and shops in every region, and few of them want a sales call. The site has to explain plans in plain American English, take payment on a phone, and get them invoicing their own customers the same day. We focus on a fast pricing page, a short sign-up and an account area they can run without support. Help content and onboarding emails are written for owners who handle their own books, not for accountants.
Larger customers now want security reviews, single sign-on, contract terms and invoices on net terms. We add a procurement section, an order form route that creates subscriptions on signature, role based access in the account area and invoice billing, while keeping self-serve plans for the rest of the market intact. Enterprise and self-serve customers share one price book, so discounts are visible and controlled rather than negotiated in email threads.
Acquisitions left you with separate sites, checkouts and billing systems for different regions or product lines. We bring them onto one platform with one price book and one customer record, migrate subscribers with their terms and payment tokens, and redirect old domains so search rankings and saved logins survive the move. Finance gets one revenue report across every former brand for the first time.
Consolidation is planned region by region, not all at once.
How we work
Most US vendors start with a fixed scope project covering the site, checkout, billing integration and migration. Afterwards, many keep a monthly retainer for new plans, new states and new integrations as they grow. Vendors with a long program of billing work take a dedicated team that joins their sprints and tools. All three are delivered remotely, with a written scope, a shared board and staging access for your staff throughout. Codeeo has delivered 200+ projects across the UAE and the US.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
National builds commonly combine Next.js or a headless CMS for the site, Stripe Billing, Chargebee or Recurly for subscriptions, Avalara, Vertex or Stripe Tax for multistate tax, and a consent tool in front of analytics. We work with the vendors you already have contracts with, and we write down why each tool was chosen so the decision can be revisited as you grow.

It depends on the number of states, payment methods, integrations and subscribers to migrate.
A self-serve site for a vendor collecting tax in a few states with one billing system is quicker than a national platform with enterprise contracts, ledger integration and a large migration. We fix the first release in discovery and write the dates down before design. Tax configuration and migration testing take the most care, so they are planned from the first week rather than left to the end.
