Services · Ecommerce development · POS subscription sites
Codeeo delivers POS subscription website development USA software companies need when their merchants sit in dozens of states. We build the plan pages, business sign-up, recurring card and ACH billing, state-by-state sales tax on SaaS and hardware, renewal and cancellation flows that follow federal and state rules, and the self-serve account where merchants manage locations and registers. Every paid sign-up opens the merchant's account in your POS platform without manual steps.
Your register app, payment terminals and offline mode stay with your product team. Our work is the national commercial layer: one site and one billing setup that can sell to a cafe in Ohio and a retail chain in Florida under the right rules for each. Your finance team changes prices and plans itself after launch.

National platform features
Selling POS plans nationally means one product and fifty sets of rules. Since the Supreme Court's 2018 decision in South Dakota v. Wayfair, a software vendor can owe sales tax in a state where it has no office, simply by selling enough there. States disagree on whether SaaS is taxable at all, and they treat bundled hardware differently again. Renewal and cancellation law is split between the FTC and a growing number of state statutes, and privacy laws differ in whether they cover business contacts.
A POS subscription platform development USA project turns that patchwork into configuration. Rules sit in the billing and tax setup, keyed to each merchant location, so expanding into a new state is a settings change and not a rebuild. The features below are the ones national vendors most often need, and we scope them to the states you actually sell in.
A tax engine watches sales by state against economic nexus thresholds and applies each state's treatment of SaaS and hardware. Some states tax remotely accessed software, some do not, and some tax only part of the charge. Product tax codes keep each line correct as you register in new states.
You learn about a new filing duty before it becomes a back tax bill.
Merchants that hold resale or exemption certificates upload them at sign-up, and the certificate is validated, stored and applied to the right locations. Expiry reminders prompt renewal before invoices start charging tax again.
Audit-ready certificate records without a shared drive.
Card entry runs in the payment provider's hosted fields or hosted page, so card numbers never touch your servers. Scripts on payment pages are inventoried and controlled, as PCI DSS 4.0.1 expects, and admin access uses multi-factor sign-in.
A simpler compliance assessment and less risk if something goes wrong.
The FTC's 2024 click to cancel amendments were vacated in July 2025, but ROSCA still requires clear terms, express consent and a simple way to stop recurring charges online. State laws in California, New York and elsewhere add reminders and cancellation duties. We build one flow and switch state rules on by the buyer's location.
One compliant flow instead of a different site for each state.
Recurring card charges with network account updater support, plus ACH debit with Nacha-compliant authorization and account validation for web entries. Retries follow decline and return codes rather than a fixed schedule.
More renewals collected without manual chasing.
National POS sales run through direct sales, ISOs, value-added resellers and franchisors. Each sign-up records its channel and partner, and recurring revenue reports by partner feed your commission or residual calculations.
Partners get paid accurately and disputes drop.
Franchisors can set approved plans and hardware for their network while each franchisee pays for their own locations. Enterprise chains get consolidated invoices, purchase order fields, net terms and per-region reporting across many states.
Large networks buy through the platform instead of around it.
Pricing, sign-up, payment and account screens built to WCAG 2.2 AA. Website accessibility lawsuits under ADA Title III are filed in federal courts across the country, and an accessible checkout also loses fewer buyers on small phone screens.
Less legal exposure and a wider pool of buyers.
A growing number of states now have comprehensive privacy laws. Most exclude people acting in a business capacity, California does not. We build a privacy notice, consent handling that honors Global Privacy Control where required, and a request workflow keyed to the requester's state.
Privacy duties handled by state without over or under complying.
Billing events reach your POS platform through its API, opening, changing, limiting or closing merchant accounts. Events are queued, retried and logged, so a network blip on either side never leaves a merchant billed without access.
Billing and product access stay in step across every account.
Who this is for
The scope of POS SaaS website development USA vendors need depends on how they sell and how far they reach. A regional platform crossing its first state lines has different priorities from a franchise POS covering several hundred locations. These four situations cover most of the conversations we have, and each one starts from a different first release.
You built your customer base in one or two states and are now selling further afield. We set up nexus monitoring, state tax rules and a renewal flow that adapts by location, so growth into a new state does not wait on legal and finance rework. State registrations and filing calendars stay visible in the admin so nothing slips as you grow.
Register for tax before you cross a threshold, not after.
Your POS is required or recommended across a franchise network. We build franchisor controls, franchisee self-serve billing and network reporting, so head office sets the standard and each owner pays for their own stores without paper forms. Franchisees who leave the network are offboarded cleanly, with their data exported and billing closed on a set date.
You sell a white-label POS next to merchant processing through agents across the country. We track agent attribution, report recurring revenue for residuals and keep software billing separate from processing so finance sees each line clearly. Agents can share a sign-up link that carries their code, so attribution does not depend on someone typing it in.
Thousands of merchants are billed through an aging system or several disconnected tools. We plan a staged move to one billing platform, clean up plan and price data, and migrate merchants in waves with clear communication at each step. Old invoices and payment history come across too, so support can answer questions about last year's charges.
A pilot wave catches data problems early.
Working with us
Codeeo has delivered 200+ projects across the UAE and the US, with a team of 80+ across Dubai, Riyadh and Karachi, and a 4.7 rating from 23 Google reviews. We work with US clients remotely, from Seattle to Miami. Discovery, reviews and sprint demos run by video call, and every decision on tax, renewal wording or billing logic is recorded in writing so your counsel and finance team can check it against the rules matrix. One project lead coordinates design, billing, tax and integration work, so your team always knows who to ask and what happens next.
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
Most national builds use a Next.js front end and headless CMS, with Stripe Billing, Chargebee or Recurly for subscriptions, Avalara or Stripe Tax for multi-state tax, a consent platform, and your CRM and ERP. We build on your current tools where they already do the job. Hosting runs on your own cloud account, with monitoring on checkout, webhooks and tax calls.

A sales site, a billing engine and the state rules that sit between them.
A national build usually includes plan and pricing pages, business sign-up, card and ACH billing, proration and plan changes, a merchant account area, a renewal and cancellation flow, a multi-state tax setup with certificate handling, partner attribution and provisioning to your POS. The rules matrix agreed in discovery decides which state-specific steps are switched on for which buyers. Scope then follows the states and channels you sell through. Where you plan to offer trials or introductory plans as part of your own sales model, the rules matrix also covers how those convert to paid billing in each state.
