Services · Mobile app development · Procurement apps
Codeeo provides procurement software development in the USA for multi state companies, federal contractors and grant funded organizations. We build purchase to pay platforms covering requisitions, approvals, supplier onboarding, contracts, receiving and invoice matching, plus the federal layer some teams need: SAM.gov records, FAR clause flow down, small business subcontracting and Uniform Guidance procurement rules. Everything is designed around the systems you already run, so control improves without a disruptive replacement.
We are a procurement software development company USA clients reach remotely, with no US office. Our team works with clients across the country, running discovery, design reviews and demos by video call, with recordings and written decisions so stakeholders in different states stay aligned.

Core capabilities
Purchasing at national scale adds problems a single site never sees. Suppliers in one state charge tax differently from those in the next. Privacy duties change with the residents whose data you hold. Federal contracts bring their own clauses, registrations and reporting, and grant money carries procurement standards of its own. A national rollout also means approvers in several time zones and business units with their own habits. The capabilities below are the ones US clients most often ask for. We choose the set and order with you in discovery, and every module draws on the same supplier record and approval engine. Requesters in the field use a mobile app that works with weak signal; buyers, approvers, accounts payable and suppliers use web portals built for their own tasks.
Requests carry entity, state, cost center and project, and approval routes follow your delegation of authority for each combination. Regional managers approve from a phone, and a request waiting too long escalates by rules your finance team edits without code changes. Delegations for vacations and leave are set by the approver, with an end date, so nothing waits on an empty inbox.
One policy applied consistently in every state you operate in.
A self service portal collects W-9 forms, insurance certificates, banking details and diversity certifications. Tax identification numbers are checked against IRS records through TIN matching where you are enrolled, and 1099 reportable vendors are flagged from day one so year end reporting does not become a scramble.
Clean vendor masters and fewer year end corrections.
For federal work, the platform records each subcontractor's Unique Entity ID and registration status in SAM.gov, and checks for exclusions before an award and on a schedule afterward. Expiring registrations raise alerts so a lapse is caught before it affects a contract. Each check is stored with the date and result, giving your compliance team a record to show during a purchasing system review.
No awards to excluded or unregistered parties.
Purchase orders under a federal prime contract attach the clauses that must flow to subcontractors, selected by contract, dollar thresholds and the type of work. Your contracts team maintains the clause library, so updates during the ongoing FAR rewrite are made once and applied everywhere.
Subcontracts carry the right terms without manual copying.
Primes track commitments to small, small disadvantaged, women owned, HUBZone and service disabled veteran owned businesses against actual payments, by contract. Data is structured for the reports your contracting officers request, and subcontractors confirm the payments they received so totals can be reconciled before anything is submitted.
Subcontracting goals evidenced with payment data.
Organizations spending federal awards must follow the procurement standards in 2 CFR 200. The system applies the right method by threshold, records cost or price analysis where required, and keeps the documentation trail auditors look for in a Single Audit.
Grant funded purchases that hold up under audit.
Purchase orders carry the correct tax treatment by ship to state, exemption certificates are stored per supplier and per state, and invoices with unexpected tax are held. Integration with a tax engine is optional where your volume justifies it. Use tax owed on untaxed purchases from out of state suppliers is calculated and reported for your tax team instead of being missed.
Fewer overpayments and fewer use tax surprises.
Goods are received on handhelds at each site, matched against orders and invoices with tolerances by category, and exceptions route to the original buyer. Federal invoices that must be submitted through government portals are tracked to payment, with prompt payment due dates visible so late federal payments can be raised promptly.
Accounts payable works exceptions, not every invoice.
National agreements, regional service contracts and state specific terms are stored with owners, renewal dates and pricing schedules. Orders check against contracted prices, and owners are warned well before an agreement renews automatically. Federal subcontracts keep their modifications in sequence so the current terms are always clear.
Negotiated terms honored in every region.
Spend by supplier, category, state, entity and contract, with diverse supplier spend, off contract buying and cycle times visible. Data flows to Power BI or your own warehouse for deeper analysis. Regional leaders see their own figures, while the national team compares regions on the same definitions.
Leadership sees national spend in one consistent view.
Who this is for
Clients ask for custom procurement software development USA wide for different reasons. These four profiles cover most of them, and each one changes which modules belong in the first release and which can wait for later. In every case the platform is built so a new state, entity or contract type can be added through configuration rather than another development project.
Retailers, healthcare groups, logistics firms and franchisors with sites in many states need one approval policy, one supplier master and tax handling that follows each location. We usually start with requisitions, onboarding and matching, then add contracts and sourcing once the basics are trusted. Regional managers keep the ability to approve local spend, while national categories such as IT, fleet and facilities go through central buyers with negotiated agreements.
One policy, many states.
Defense and civilian contractors need SAM.gov checks, clause flow down, subcontracting plan reporting and controls over who can see technical data. Where contracts carry Defense Department cybersecurity requirements under CMMC, hosting, identity and logging decisions are made with that in mind from the start. Purchasing also links to project charge codes, so costs land on the right contract for billing and incurred cost reporting.
Federal controls built in, not bolted on.
Organizations spending federal awards have to follow the Uniform Guidance procurement standards and show it during a Single Audit. A system that applies the right method by threshold and keeps the file for each purchase reduces findings. Conflict of interest declarations, competition records and suspension and debarment checks sit in the same file, ready for auditors and pass through entities.
Some clients are building a procurement product of their own for public or private buyers. We act as the engineering team, and plan for FedRAMP or state programs such as TX-RAMP early if the product will host government data. You own the code and the roadmap; we build to your product decisions and hand over documentation that lets your own engineers take over whenever you are ready.
How we engage
Most US clients begin with a fixed scope first release, then keep a retainer for integrations and new modules. Organizations with a long roadmap take a dedicated team of procurement software developers USA leadership directs through its own backlog. Codeeo has a team of 80+ across Dubai, Riyadh and Karachi and has delivered 200+ projects across the UAE and the US. We work remotely, and every review ends with written decisions. Whichever model you choose, repositories, documentation and cloud accounts stay with you, so the platform can move in house later without a rebuild.
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
React and Next.js for buyer and supplier portals, React Native or Flutter for mobile approvals and receiving, Node.js or .NET for services, PostgreSQL for data, and AWS, Azure or Google Cloud in your own account, including government regions where your contracts call for them.

State by state differences, federal rules and a phased rollout.
Tax treatment, privacy duties and public sector vendor programs vary by state, so the rules engine has to hold state as a dimension rather than a hard coded assumption. Federal contractors and grant recipients add their own layer of registrations, clauses and documentation. Rollout across regions needs training, data cleanup and support planned in waves. We map all of this in discovery so the first release is built on the right structure.
