Illinois custom software development company.

• A Chicago or suburban agency

  Incorporated in Illinois, on Central time from open to close, able to sit at your table. You are buying proximity, a domestic invoice and a procurement file with nothing unusual in it. Right for work that needs hands on a trading floor, a dock or a plant line, or a purchasing process that expects a supplier in the state.

• A staffing or contract firm

  Engineers billed by the hour into a process you run. You are buying capacity; architecture, code review, QA and release management stay with your own lead. Right when you already have an engineering manager with the time to direct more people.

• A remote engineering partner

  A small senior team that owns a defined build, works your morning from outside the country and hands over the repository at the end. There is no local entity, so the contract, the tax form and the security questionnaire need doing properly on day one. Right when you know what the system must do and want it built well the first time.

We are the third. When the first or second is the better answer for your project, you hear it on the first call rather than after a deposit.

• A remote partner is right when

  • ✓The system’s job can be written down, and one person on your side can decide without a committee.
  • ✓The work is a defined build, rebuild or extension rather than a programme whose sponsor changes each quarter.
  • ✓Four live hours in the Central morning are enough for decisions, and the afternoon can run on a written handover.
  • ✓You want the repository, the pipeline and the documentation in your own hands rather than held as a reason to keep paying.
  • ✓Regulated data is involved and your compliance or risk lead will set the rules and review the evidence we produce against them.

• Hire in Illinois instead when

  • ✓Your purchasing rules, a grant condition or a flow-down clause from one of your own customers require a supplier incorporated in the United States.
  • ✓Somebody has to be physically present: a cutover on a trading desk, scanners on a dock, a device on a production line.
  • ✓Your security policy forbids production access from outside the country and the work cannot be done against masked data.
  • ✓Your decision-makers are only free after lunch Central time and the build cannot run on a morning-plus-handover rhythm.
  • ✓What you really need is contractors under your own architect, in which case a staffing firm costs you less management than we would.

• 01

  Start with the rows we lose.

  A table one supplier wins outright is a brochure. The rows above where a local agency wins are real, and a buyer who finds them here has been served better by this page than by a pitch.

• 02

  Where the engineers sit and where the system runs are two facts.

  Your platform can live in a US cloud region under your own account, with production access limited to whom you choose, while the people writing it work from Ahmedabad. Most of a risk conversation gets simpler once that distinction is on the table.

• 03

  Capacity is not delivery.

  Contractors add hands to a process you already run. If nobody on your side holds architecture, review and release quality, more hands produce more code, not a working system.

• 04

  US-only clauses are binary, so ask early.

  A federal grant condition, a customer flow-down or a purchasing rule requiring work performed in the United States rules us out, and engineering quality does not change that. Raise it on the first call and the answer comes the same day.

• Desk tooling

  Trading, clearing and back-office tools

  Allocation, reconciliation, position and risk dashboards, approvals and reporting for trading and clearing firms, built with the audit trail and record retention your compliance officer already expects and integrated with the order-management and market-data systems you run.

• Freight

  Transport, yard and intermodal systems

  Dispatch, appointment and dock scheduling, drayage tracking, proof of delivery and exception handling for carriers, 3PLs and shippers working the rail yards, O’Hare cargo and the distribution belt along I-55 and I-80, with EDI and API links to the TMS and WMS around them.

• Plant

  Manufacturing and quality software

  Work orders, bills of materials, lot and serial traceability, job costing and inspection records for plants in Rockford, Peoria, Elgin and the Quad Cities, with mobile capture for the floor and a reporting layer the plant manager reads on a phone.

• Clinic

  Clinic operations and care coordination

  Scheduling, intake, referral tracking and follow-up workflows beside the EHR for physician groups, behavioural-health providers and home-health agencies across Cook County and the collar counties, built to the HIPAA Security Rule safeguards.

• Food

  Food production and traceability

  Lot tracking, supplier records, temperature and sanitation logs, recall drills and preventive-controls documentation for processors and distributors, so the record a food-safety inspector asks for is a query rather than a binder.

• Product

  SaaS products and first versions

  Tenanted products with billing, roles, usage limits and an audit history, for a founding team in Fulton Market or at 1871, or for a company turning an internal tool into something it can sell.

1. Discovery, then a scope on paper

   One call to trace how the work moves today, who touches it and where it breaks, then a written scope with the exclusions named. No estimate leaves here on the strength of a conversation, and the document is yours either way.

   A scope, a price range for phase one and the name of the engineer who would lead it.

   48 hours

2. Prototype and architecture

   Clickable screens in the first week so your operations lead reacts to something real. Alongside them the data model, permission scheme, hosting region and rollback plan, agreed in writing before an editor is opened.

   Approved screens, an architecture note your CTO can read, and a data-handling position your compliance lead has seen.

   1–2 weeks

3. Build in two-week slices

   Working software demonstrated every fortnight in your morning, against your own records rather than sample data. Each slice is checked against the scope with you on the call, so progress is seen rather than reported.

   Modules proven against real cases, and a backlog you have shaped as you went.

   6–14 weeks, by scope

4. Harden, then go live

   Permissions, load, backups, monitoring and a rehearsed rollback signed off before anyone in Illinois logs in. Where a retention rule or an audit trail is required, it is delivered here and not promised for later.

   A release your risk desk can accept, with the evidence attached.

   2–3 weeks

5. Operate and extend

   Monitoring, a support window on Central hours, and the next slice of roadmap chosen from what your users actually do rather than what the plan assumed in month one.

   Software that keeps paying for itself, and a team that can hand it to yours whenever you want.

   Monthly, 30 days notice

• First system

  Retiring the spreadsheet that runs the desk or the dock

  A dispatch grid, an allocation workbook, an approvals inbox and one person who knows the exceptions, replaced by a system with roles, an approval trail and a record of who did what and when. For operations, trading-ops and finance teams.

• Rebuild

  Replacing a system that has aged out

  A desktop tool, an Access database or an early web app rebuilt as something maintainable, without losing fifteen years of records or retraining a whole floor in one weekend. For teams on software nobody supports any more.

• Finding

  Bringing a live system up to its obligations

  Adding biometric consent and deletion schedules, an unalterable audit trail, retention rules or breach-scoping logs to software built before anyone asked. A finding, a demand letter or a deadline is usually what starts it. For teams facing an audit, a claim or a new rule.

• Extension

  Building around the system of record

  Portals, modules, dashboards and interfaces layered over a TMS, an ERP, an order-management system or an EHR, so the record stays where it is and the retyping around it disappears. For companies extending rather than replacing a core.

1. 01

   Trading, clearing and financial services

   The Loop is home to exchanges, proprietary trading firms, clearing houses and the vendors around them, and the tooling they run on tends to be an internal build that has outgrown its author. Allocation, reconciliation, position and risk views, approvals and reporting, built with the retention and audit trail your compliance officer already expects and kept out of the way of the systems that touch the market.

2. 02

   Freight, rail and logistics

   Chicago is where the railroads meet, O’Hare moves cargo around the clock and the intermodal yards around Joliet and Elwood feed a distribution belt along I-55 and I-80. Dispatch, appointment and dock scheduling, drayage tracking, proof of delivery and multi-site inventory, with EDI and API links to the TMS and WMS on either side.

3. 03

   Manufacturing

   Rockford, Peoria, Elgin, the Quad Cities and the industrial suburbs carry machine builders, fabricators, packaging and component plants. Work orders, bills of materials, lot and serial traceability, job costing and inspection records for plants that still run part of the day on paper travellers.

4. 04

   Healthcare networks and physician groups

   Hospital networks in the city and the collar counties, and the physician groups, behavioural-health and home-health providers around them, run scheduling, referral and intake tools never designed for the volume. We build beside the EHR rather than against it, to the HIPAA Security Rule safeguards and the rules your privacy officer sets.

5. 05

   Food production and distribution

   Processors, bakeries, meat and dairy plants and distributors across the city and downstate, whose lot records, temperature logs and supplier files still live in binders. Traceability, sanitation and preventive-controls records that a food-safety inspector can pull as a query, and a recall drill that takes minutes rather than a weekend.

6. 06

   Insurance and professional services

   Underwriting workbenches, claims intake, broker portals and document workflows for the insurers, brokers and firms concentrated in Chicago and Bloomington-Normal. Approval chains, segregation of duties and a complete audit trail are the requirements that shape the build.

7. 07

   Technology companies and research spin-outs

   Data-heavy products, pipeline and instrument integrations, and the first commercial platform a research-led team from Champaign-Urbana or Hyde Park builds when a tool it made for itself turns out to be worth selling. CyberFind, a vendor decision platform for CISOs, is the shape of that work: four years in production without a rewrite.

If your sector is not listed, our first question is the same one anyway: what does a day of this work look like, and where does it break?

1. 01

   Biometric Information Privacy Act (BIPA)

   The Illinois statute. Illinois’s biometric statute is the one most companies have heard of, because private individuals enforce it themselves. The Biometric Information Privacy Act, 740 ILCS 14, requires a private entity to publish a written retention and destruction schedule, to inform a person in writing and obtain a written release before collecting a fingerprint, faceprint, voiceprint or similar identifier, and never to sell or profit from that data. It is enforced through a private right of action, which is why it produces so much litigation: an individual can sue for each violation without proving separate harm. The Act was amended in 2024 so that repeated collection of the same identifier from the same person by the same method counts as a single violation, and to allow the written release to be electronic. Engineering consequence: consent capture, the retention schedule and deletion are part of the data model, not a policy page. A time clock, a visitor kiosk, a face-matching login or a voice feature each need the consent record stored beside the identifier and a destruction job that provably runs. Whether a feature collects a biometric identifier at all, and how the release must be worded, is a question for your counsel. What we build is a system in which the answer is provable: consent stored per person, a schedule the system enforces, and a deletion log that survives an audit. Re-verify the amendment text before relying on this row. Sources: Biometric Information Privacy Act, 740 ILCS 14, as amended in 2024 · Enforced through a private right of action in Illinois courts; Illinois General Assembly for the statute text.

2. 02

   Personal Information Protection Act (PIPA)

   The Illinois Personal Information Protection Act, 815 ILCS 530, requires a data collector that owns or licenses personal information about an Illinois resident to notify that resident of a breach in the most expedient time possible and without unreasonable delay, and to notify the Attorney General when a breach affects more than a resident count the Act sets. It also requires reasonable security measures to protect records from unauthorised access. Enforcement sits with the Office of the Illinois Attorney General. Illinois has no comprehensive consumer data privacy statute of the kind in force in a number of other states as of this writing; bills are introduced in Springfield most sessions, so this row is dated. The consequence today is that privacy obligations come from BIPA, from PIPA, from the federal sector rules below and from the laws of the other states whose residents you serve. The notification decision, its timing and its wording belong to your counsel and your incident plan. What we build is the ability to answer the question accurately: retained access logs, an audit trail that cannot be edited, alerting on unusual access and a rehearsed way of reconstructing which records were reached and by whom. Re-verify the current thresholds before publish. Sources: Personal Information Protection Act, 815 ILCS 530 · Office of the Illinois Attorney General.

   Breach notice

3. 03

   Artificial Intelligence Video Interview Act

   For an Illinois employer using artificial intelligence to analyse recorded video interviews, the Artificial Intelligence Video Interview Act, 820 ILCS 42, requires notice to the applicant, an explanation of how the tool works and what it evaluates, the applicant’s consent, limits on who may share the video, and deletion on request within the period the Act sets. A hiring portal or applicant tracking system with any automated video analysis has to carry those steps in the workflow rather than in a policy. Whether a feature falls under the Act, and how consent and explanation must be presented, is your counsel’s call. We build the consent step, the sharing controls and the provable deletion.

4. 04

   HIPAA Security Rule technical safeguards

   Where a system holds protected health information we build to the technical safeguards in the HIPAA Security Rule: unique user identification, role-scoped access, automatic logoff, encryption in transit and at rest, integrity controls and an audit trail that records who viewed a record, not only who changed it. Minimum necessary is decided in the data model at design time rather than argued about after go-live. A business associate agreement is not something we promise on a web page. Whether one is needed and what it says is your privacy officer’s and your counsel’s decision. We build to the safeguards, work under your compliance team’s rules and give them the engineering evidence to sign off.

   Health data

5. 05

   GLBA Safeguards Rule and financial record-keeping

   A lender, broker, insurer or other financial institution holding customer financial information is expected to maintain an information security programme under the Gramm-Leach-Bliley Act, and the FTC’s Safeguards Rule sets out what a non-bank institution’s programme must include: access controls, encryption, multi-factor authentication, logging and monitoring, change management and a tested incident response plan. Trading and clearing firms carry their own record-retention and supervision obligations under their regulators and exchanges, and a system that touches trade or communication records has to keep them in the form and for the period those rules require. Which supervisor’s or exchange’s rules apply is a question for your compliance officer. What we build is software that satisfies the technical controls whoever is asking: least-privilege access, multi-factor authentication, encryption, complete logging, immutable retention and a change history a reviewer can read. Sources: Gramm-Leach-Bliley Act; FTC Safeguards Rule, 16 CFR Part 314 · Federal Trade Commission, and the relevant prudential or market regulator for the institution.

   Financial data

6. 06

   PCI DSS, kept out of your codebase

   The safest way to handle card data is never to hold it. We tokenise at the processor, so the card number is captured in the processor’s own hosted field or SDK and your system stores a token, a brand and the last four digits. Your application never sees or stores a primary account number, which keeps most of the PCI DSS scope out of the code we write. Plugin, a club management system we built, takes bookings and payments through Stripe. Your PCI obligations remain yours, and which self-assessment questionnaire applies depends on how you take payments. We keep the scope small and say plainly when a requested feature would widen it. Sources: PCI DSS v4.0.1 · PCI Security Standards Council.

   Payments

We build systems that produce this evidence as a by-product of normal use rather than bolting a compliance module onto software that resists it. When a finding, a claim or a deadline is driving your timeline, that date is where the plan starts.

1. 01

   Governing law and contract form

   We sign your master services agreement under Illinois law, with the venue, liability, indemnity and termination terms your counsel wants. We do not ask a client to contract under Indian law, and we do not run projects on an exchange of emails.

   Your paper

2. 02

   Tax form and invoicing

   As a non-US entity we send a completed Form W-8BEN-E to your accounts payable team before the first invoice. Invoices are in US dollars, against the milestones or the monthly rate in the contract, carrying whatever purchase order reference your finance system needs.

   W-8BEN-E

3. 03

   Ownership of the work

   Code, designs, infrastructure definitions and documentation are assigned to you as they are created, not on final payment. Repositories, cloud accounts and domains are opened in your name from the first commit, and every engineer on the account works under the same assignment and confidentiality terms.

   Assignment

4. 04

   Confidentiality

   An NDA is signed before you share anything sensitive, yours or ours, mutual by default. Your name, your product and your project appear nowhere as a reference without written permission.

   NDA

5. 05

   Security review and insurance

   Certificates of insurance are available on request. Vendor risk questionnaires are answered by the engineers who would do the work, describing what we actually operate, with every no written as a no and the compensating control beside it.

   Vendor risk

6. 06

   Background checks

   If your policy requires checks on named engineers, common for trading, healthcare and insurance work, we arrange them and return the results through your process. Raise it at contract stage, because it adds time before anyone can start.

   On request

7. 07

   No entity in the United States, and what that rules out

   QalbIT has no United States entity, no Illinois office and no employee who can be in Chicago on a Tuesday. Where a purchasing rule, a grant condition or a customer flow-down requires a domestic supplier or work performed on US soil, we are not eligible, and you will hear that on the first call rather than after a proposal.

   The limit

None of this argues against a remote partner. It argues for doing the paperwork properly at the start instead of assuming it away, which is why we raise it before the estimate and not after the contract.

• A note on sourcing

  A note on sourcing

  There are no market figures on this page: no Illinois salary bands, no agency rates, no failure-rate statistics that circulate without a primary source. The only numbers are our own and our clients’, each naming where it comes from. The Plugin and Snappy Stats outcomes above are as stated in those case studies. If a figure matters to your decision, ask for the source and we will send it or withdraw the claim.

1. 01

   Eight years of this kind of work

   Custom software since 2018: 120+ engagements delivered for 50+ clients across web, mobile and platform work. Clutch 5.0 from 8 reviews, Google 4.9 from 18 reviews, 100% job success on Upwork. Those are the figures we can evidence and the only ones we quote.

2. 02

   Named proof, not a logo wall

   CyberFind, a B2B vendor review platform for security leaders, has run four years in production without a rewrite and carries 500+ verified CISOs and 2,000+ peer reviews. Plugin, a club management system with Stripe payments, took a tennis club from three tools to one and cut double-booked courts sharply. Snappy Stats, a Laravel scheduler for a shooting academy, cut double bookings by 80% and freed 3–4 hours a week of admin. Each is written up on this site with what went wrong as well as what went right.

3. 03

   Your morning is our commitment

   Four live hours every working day, 07:30 to 11:30 CT, with stand-ups, demos and decisions inside that window and a written handover before our night ends. Nothing waits for a weekly status meeting.

4. 04

   We say exactly what we are

   No Illinois office, no Illinois staff, no United States entity and no implied presence anywhere on this site. The compliance and paperwork sections above exist because we would rather lose a deal at the scoping call than at the risk review.

5. 05

   We will tell you to hire in Illinois

   When a firm in Chicago, Naperville or Peoria is honestly the better answer, you hear it on the first call. It costs us a project and saves you a year, and it is why a fair share of our work arrives by referral.
