Custom Financial & Enterprise Software
The hardest thing we build — compliant financial and operational software for retail, construction, hospitals, and institutions.
Financial and enterprise software is the category where most software vendors quietly bow out. It's not a landing page or a CRUD app — it's money moving between accounts, reconciliation against a POS or bank feed, audit trails a regulator can follow, and data models that have to be right the first time because a wrong balance costs someone real dollars. We build this category specifically: retail ledgers, ERP slices, construction job costing, hospital billing, and institutional finance, each with its own compliance shape and its own definition of "done."
Our clients are operators who've outgrown spreadsheets and off-the-shelf software but don't need, or can't afford, a full enterprise suite. A multi-location retailer needs sales reconciliation and vendor settlement tied to their existing POS, not a new POS. A general contractor needs AIA-style progress billing and retention tracking that matches how subs actually get paid, not a generic project management tool bent sideways. A hospital needs claims workflows and HIPAA-aware handling around patient billing, not a rebuilt EHR. We scope to the module that matters and build outward — GL, AP/AR, procurement, treasury — rather than selling a rewrite of everything you already have.
The stack — Next.js, Node.js, TypeScript, PostgreSQL, Stripe, AWS — is chosen for this kind of work specifically: typed code end to end to keep financial logic provable, Postgres for the transactional integrity ledgers require, Stripe where payment processing is actually needed, AWS for the audit logging and access controls institutional buyers expect. A focused module ships in 10-16 weeks; a full multi-module suite runs 5-9 months — timelines we hold because scope is fixed before we write code, not discovered halfway through.
Our process
Ledger & Workflow Mapping
We map your actual money flows first — POS reconciliation, AIA progress billing, insurance claims, or grant ledgers — fixing module scope before any code gets written.
Data Model & Compliance
PostgreSQL schemas get built for audit trails and transactional integrity from day one, with HIPAA-aware handling designed in for hospital and clinical payroll modules.
Modular Typed Build
Next.js and Node.js modules ship one at a time — GL, AP/AR, subcontractor payouts, tuition billing — each wired into your existing POS, Stripe, or payroll systems.
Reconciliation & Handoff
We test against real transaction volume and reconcile every ledger before launch, then deploy on AWS with the access controls and audit-ready reporting your auditors expect.

Custom Financial & Enterprise Software
Custom financial and enterprise software is purpose-built software that handles how an organization records, moves, reconciles, and reports money, in places where off-the-shelf tools do not fit. Prixelo builds it for operators who have outgrown spreadsheets and packaged software but do not need a full enterprise suite: multi-location retailers, construction firms, hospitals and clinics, and schools or other institutions. Rather than replacing everything, we usually deliver one to three focused modules, such as a general ledger, AP/AR, billing and invoicing, payment reconciliation, job costing, or multi-entity reporting, integrated with the accounting, POS, or payment systems you already use. Every module includes role-based access and audit trails on record changes. A focused module typically ships in 10-16 weeks, and a multi-module financial suite in 5-9 months, with the first usable slice live within the first 12 weeks. Scope is fixed before code is written.
Questions buyers ask
What does custom financial and enterprise software include?
It includes the specific financial modules your business needs, not a whole ERP. Typical pieces are a general ledger, accounts payable and receivable, billing and invoicing, payment and bank reconciliation, procurement, treasury, and multi-entity reporting. Each module comes with role-based access, audit trails on every record change, and integrations with the POS, payment, payroll, or accounting systems already in place.
When should a business build custom financial software instead of buying off the shelf?
Build when your money flows do not match what packaged software assumes and workarounds have moved into spreadsheets. Common signs are manual reconciliation between a POS and the books, progress billing and retention handled outside the system, or claims and grant tracking that no standard tool models well. If an existing product fits your process, buying it is usually the better choice.
What is the difference between a custom ERP module and a full ERP system?
A custom module covers one financial area, such as job costing or vendor settlement, and connects to the systems you keep. A full ERP tries to cover finance, inventory, HR, and operations in one product. Prixelo builds the modules that general ERPs handle poorly and leaves the rest of your stack in place, which keeps scope, cost, and risk smaller.
How does construction job costing and progress billing software work?
It tracks costs against each project and bills clients as work progresses. The software records labor, materials, and subcontractor costs per job, produces AIA-style progress invoices, holds back retention until it is due, schedules subcontractor payouts, and reports profit and loss per project, so a contractor can see margin on each job instead of only at year end.
What do hospitals and schools need from financial software?
They need billing and ledgers that follow their own rules. Hospitals and clinics typically need patient billing, insurance claim workflows, and payroll for clinical staff, with HIPAA-aware handling of patient data. Schools and institutions usually need tuition billing, donor and grant ledgers, departmental budgets, and reports that are ready for auditors.
How is financial data kept accurate and auditable?
Accuracy comes from the data model and from testing against real transactions. Ledgers are built on PostgreSQL for transactional integrity, logic is written in typed TypeScript, and every change to a record is logged so an auditor can trace who changed what and when. Before launch, ledgers are reconciled against real transaction volume rather than sample data.
