01 / What we build
What we build
Building a product you will sell rather than software your business runs on? That is a different job: see MVP development for founders.
02 / Who we work with
Who we work with
Established businesses
Whose operation has outgrown its tools: the process is the reason customers choose you, and it currently lives in spreadsheets, side files and four systems that never agree.
Organizations modernizing
A system that works but cannot keep up, where switching it off for a rewrite is not an option.
Teams with an in-house application
That need more engineering capacity, an integration, or someone to take over a project another team started.
03 / When to build
When custom software is the right call, and when it is not
We will say so on the first call. Two guides go deeper: should we build custom software and five situations where you should not.
04 / Engagement
How an engagement works
Three ways to work with us.
They differ in who is accountable for the result, not only in how the invoice is built.
Fixed-scope project
- Accountable for delivery
- Logic Square, against an agreed scope, deliverables and timeline
- Directs the day-to-day work
- Logic Square, with your sign-off at each milestone
- When it fits
- You can describe what you need today and want a price that holds
Dedicated team
- Accountable for delivery
- Shared: we answer for our part against agreed goals; you set priorities
- Directs the day-to-day work
- Our project lead, working to your product owner
- When it fits
- The product will keep changing and you want the same team over months
Staff augmentation
- Accountable for delivery
- You. Our engineers work inside your team and process
- Directs the day-to-day work
- Your engineering lead
- When it fits
- You already run an engineering team and need senior capacity or a specific skill
05 / Cost
What it costs
We publish real numbers rather than a range copied from other agencies. From delivered work: a focused marketplace MVP for an outside client was quoted at $15,000 and finished at $24,000 after the client added features; full products with a backend, web and mobile apps have run $40,000 to $93,000. These are individual projects, not packages and not limits on what a new project costs. Year-one maintenance runs about 20 percent of the build. The projects that stayed on budget settled their changes in design, not in code. The custom software cost guide shows each project, quoted and delivered, and the cost calculator gives a directional range without an email.
What moves the number
How many user roles there are and what each can see; the platforms (web, iOS, Android); payments and anything that touches money; integrations with systems you do not control; data you need to migrate; how much of the old system must keep running during the switch; security or compliance requirements a client, auditor or investor will check; and AI features that need evaluation, not just an API key.
Will the final bill match the estimate?
On a fixed price, the price holds unless you approve a priced change request; on one fixed-price build we delivered 950 hours against an 800-hour estimate at the same price. On time and materials, you get the reporting, budget limits and milestone reviews to keep it honest. Either way you get a ballpark early, after the first conversation, not after a month of discovery.
06 / The team
Who does the work
Senior engineers, with direct access: no account-manager wall between you and the people writing the code. Logic Square is a team of about 20, with US offices in Kokomo, Indiana and San Carlos and San Diego, California, and engineering in Kolkata and Gurugram. Our founder, Vineet Harbhajanka, started as a developer at Epic Systems in 2010 and founded the company in 2012; more on who we are.
07 / Ownership
Ownership, access and continuity
You own the custom software deliverables developed specifically for your project upon full payment, as defined in your agreement. Logic Square retains its pre-existing tools, components and know-how, while third-party and open-source software remains subject to its own licenses. We provide the agreed source code, documentation and handover materials so your team can continue developing and operating the system.
We build so leaving would be easy, because a platform you cannot leave with is not an asset.
08 / Security
Security and data handling
We design business software with role-based permissions, data protection, audit logs, change tracking and reconciliation controls appropriate to the requirements of each project. Where a client has specific regulatory or audit obligations, we work with its security and compliance stakeholders to build in the technical controls they need. That has meant HIPAA-aware handling on a healthcare commerce platform, FERPA- and COPPA-aware design for school networks, and access controls and audit logging on a signing platform where Logic Square built the controls that supported CloseWise’s SOC 2 certification; the client’s internal team completed the audit. We describe these as design discipline, not certifications we hold.
09 / Three builds
Three builds, at the workflow level
CloseWise
A signing company’s order-to-payout system.
For CloseWise we built one backend behind the company, agent, client, admin and white-label experiences. Each order carries its money: the client invoice and the agent payout follow the order’s outcome, including cancellations and partial work, with duplicate billing and duplicate payouts prevented by design. Agent offers go out in timed stages instead of a blast. The platform has been engineered to support more than $21 billion in loan closings.
Read the case study →Sales by Summit
Four systems onto one data model.
Sales by Summit ran CRM, payroll, commissions and scheduling in four systems that never agreed. We put one data model under all four, so reconciliation disappeared structurally rather than being automated. The client reports that the commission run, which took its CFO four to six hours every two weeks, now takes about 30 minutes.
Read the case study →CES Academy
An audit platform, then the client’s own rebuild.
For CES Academy, ten Cognia-accredited Florida campuses, a three-person fixed-cost team built the audit platform in two months; it launched in August 2022 and has run 1,200+ audits, with report preparation down from days to under four hours, as the client reports. In 2026 CES built a new version in Lovable and engaged us to review, test, deploy and manage it.

10 / FAQ
Common questions
What are custom software development services?
Designing, building and maintaining software for one organization’s workflow, rather than licensing a product built for everyone. For us that means web applications, operations platforms, portals, integrations, modernization and takeovers of existing code.
How much does custom software development cost?
In our delivered work, a focused marketplace MVP for an outside client was quoted at $15,000 and finished at $24,000, and full products with web and mobile apps have run $40,000 to $93,000, plus about 20 percent a year for maintenance. Roles, platforms, money, integrations, migration and compliance move the number most; the cost guide shows each project.
How long does it take?
It depends on scope, and we give you a range after the first conversation. Delivery is phased, so working software is in use before the full rollout; one audit platform went from scoping to launch in two months with a three-person team.
Who owns the code and IP?
You own the custom software deliverables developed specifically for your project upon full payment, as defined in your agreement. Logic Square retains its pre-existing tools, components and know-how, while third-party and open-source software remains subject to its own licenses. We provide the agreed source code, documentation and handover materials so your team can continue developing and operating the system.
Who writes the code, and what can we see while it is built?
Senior engineers you can talk to directly. You see the roadmap, the repository and progress as it happens, and you review working software at each milestone rather than status reports.
What will the proposal include, and what will it leave out?
A written scope by feature and role, what is explicitly out of scope, the integrations and data migration included, the environments and deployment, the testing depth, documentation and handover, the warranty period, and how changes are priced. If a line is not in the proposal, ask; the MVP cost guide lists the questions that separate a $8,000 quote from a $60,000 one.
How are milestones and scope changes handled?
Each milestone ends with working software you review against the acceptance criteria agreed in design. A change is written up with its cost and effect on the timeline, and nothing is built until you approve it. On a fixed price the price holds unless you approve a priced change; we have absorbed overruns on fixed-price work. On time and materials, you get reporting, budget limits and milestone reviews.
What if we do not have detailed requirements yet?
That is normal, and it is what the workflow mapping stage is for. A clickable prototype usually settles more questions than a requirements document.
Can you work inside our existing application, or take over a project another team started?
Yes. We start with a review of the code, the hosting and the data, and tell you whether to extend it, repair it or rebuild parts of it before quoting the work. That is how we took over Grouped’s inherited code and launched it on schedule, and took CES’s own Lovable build into production.
How do you protect live data during a modernization?
By not switching everything at once. We move the system slice by slice, so the old one keeps running while each part moves across, and data integrity comes before speed: data is migrated, checked against the source and reconciled before anyone depends on the new version. More in legacy system modernization.
Can you integrate with the systems we already use?
Yes, within what each vendor allows. We start from the vendor’s documented API or export, not the sales page, and design around what is actually available.
What does support after launch cover?
Optional maintenance: dependency and security updates, compatibility, bug fixes, monitoring and small improvements, at about 20 percent of the build a year, or prepaid hour blocks when needs vary. New phases as you need them, or a clean handover to your own team.
How does a US company work with your team in India?
US offices and engineering in India, under one company and one contract.
