Software Development Services for Atlanta Companies
Atlanta businesses usually come to us for one of these four kinds of work.
ERP Extensions and Migration Support
Custom applications and integrations that sit beside your ERP, so custom logic stays outside the core during an upgrade or migration.
Manufacturing and Supply Chain Software
Quoting, configuration, order tracking and supplier portals for manufacturers and distributors, including engineer-to-order shops.
Web and Mobile App Development
Full-stack web applications and mobile apps for Android and iPhone, from MVP development to a full release.
What Is Custom Software Development?
What Is Custom Software Development?
Custom software development is designing and building software around one company's processes, data and customers, rather than adapting the company to fit off-the-shelf software sold to everyone.
You'll also see it called bespoke software development or tailored software development. The terms mean the same thing: software you commission, built to your requirements, and owned by you.
For Atlanta companies, custom software often shows up next to a large system that already exists, such as an ERP, a warehouse system or a learning platform. It handles the work that the large system does badly or not at all.
For the full service, see custom software development.
What Atlanta Businesses Build
Atlanta's economy is unusually broad, and so is the software its companies commission:
- Supply chain and transportation. Freight, distribution and transportation companies need tracking, scheduling and partner portals.
- Payments and financial technology. The Atlanta area is often called "Transaction Alley" for the number of payment companies based here. See fintech software development.
- Healthcare and health IT. Clinical, billing and patient-facing software for providers and health-tech companies. See healthcare software development.
- Education and training. Learning management software and training portals for schools, universities and corporate learning teams. See education software development.
- Manufacturing. Plants across Georgia, many of them building to order. More on that below.
We work with companies across metro Atlanta, including Alpharetta, Marietta, Sandy Springs, Duluth and Peachtree Corners, and elsewhere in Georgia.
Before SAP ECC Maintenance Ends: What Happens to Your Custom Code
Many Atlanta manufacturers, distributors and retailers run SAP. SAP has said that mainstream maintenance for the core SAP Business Suite 7 applications, which include SAP ECC, runs until the end of 2027. Optional extended maintenance runs until the end of 2030 at a premium of two percentage points on the existing maintenance basis. SAP S/4HANA is committed until the end of 2040.
The hardest part of most of these moves isn't the ERP itself. It's the years of custom code built inside it: reports, approval workflows, pricing rules and integrations that someone wrote into the old system. During a migration, each of those needs a decision:
| Decision | When it fits |
|---|---|
| Retire it | The standard ERP now does the job, or nobody uses it anymore |
| Rebuild it inside the new ERP | It is small, stable and truly ERP logic |
| Rebuild it beside the ERP | It changes often, serves people outside finance and operations, or is what sets your business apart |
"Beside the ERP" means a separate application that connects to the ERP through its APIs. That keeps the ERP core close to standard, so future upgrades are simpler, and keeps your own logic in software you control.
We don't implement SAP. Your SAP partner handles the ERP. We build the custom applications and integrations around it, and we can work alongside your SAP partner on the inventory of what to retire, rebuild or move.
Engineer-to-Order Manufacturing Software
In engineer-to-order (ETO) manufacturing, each order is designed, at least in part, after the customer places it. Custom machinery, industrial equipment, architectural products and specialty vehicles all work this way. Most ERP and manufacturing systems are built for repeat production, so ETO shops end up running their real process in spreadsheets and email.
The software ETO manufacturers ask for usually covers:
- Quoting and configuration that turns a customer's requirements into a priced quote, using your own engineering rules
- A bill of materials for each order, generated from the configuration rather than copied and edited by hand
- Engineering change tracking so a design change after the order is placed reaches purchasing and the shop floor
- Order status that customers and sales can see without calling engineering
The value is in capturing your engineers' rules in software, so a quote that once took days of back-and-forth can come out consistently. For our wider manufacturing work, see manufacturing software development.
The Software Development Life Cycle, and What You Decide at Each Stage
The software development life cycle (SDLC) is the sequence every software project goes through, from idea to support. Most descriptions explain what the developers do at each stage. What matters more to you is what you decide:
| Stage | What happens | What you decide |
|---|---|---|
| Discovery | Goals, users, data and existing systems are mapped | Which problem to solve first, and what success looks like |
| Design | Screens, workflows and system structure are agreed | Whether the design fits how your people actually work |
| Build | Features are developed in short cycles and shown as they're done | What to change while it's still cheap to change |
| Testing | Functions, security and performance are checked | Whether it's ready for real users |
| Release | The software goes live, often to a small group first | When and to whom it rolls out |
| Support | Fixes, updates and new features after launch | What to improve next, based on real use |
Projects go wrong when these decisions get skipped or made by the wrong person, not when code is written slowly. For what predicts failure, see why software projects fail.
Georgia's New Privacy Law and Breach Notice Rules
Georgia now has a comprehensive privacy law. The Georgia Consumer Privacy Protection Act (Senate Bill 111) was signed on May 11, 2026, with an effective date of July 1, 2026. It follows the model used by Virginia and several other states.
- Who it covers: businesses that handle the personal data of a large number of Georgia consumers. The threshold is set by the number of consumers, and lower if a business earns a significant share of revenue from selling data.
- Consumer rights: consumers can access, correct, delete and get a copy of their data. They can also opt out of its sale, targeted advertising and certain profiling.
- Enforcement: by the Georgia Attorney General.
For software, that means you need to find a person's data across your systems, export it, correct it, delete it, and record their opt-out choices so every system respects them. The final text was amended in the House before passage, so have your counsel confirm the exact thresholds and deadlines.
Breach notice. Georgia's breach notification law, O.C.G.A. § 10-1-912, requires notice to affected residents "in the most expedient time possible and without unreasonable delay." If more than 10,000 Georgia residents must be notified at one time, the nationwide consumer reporting agencies must also be told. The statute is written around information brokers and government data collectors, so whether it covers your business depends on what you do with data. Your counsel should decide that.
Either way, the software questions are the same: which records were exposed, whose they were, and how to reach them. Audit logs and a data inventory answer those. We build them. Your counsel decides what the law requires of you.
Working With Our Software Developers From Atlanta
What working with our software developers looks like once an Atlanta project starts.
TIMEZONE
Eastern Time Overlap, Built Into the Schedule
Atlanta runs on Eastern Time. Our schedule includes a daily overlap with your working day, agreed before the project starts. That's when reviews, demos and approvals happen. Outside it, work continues and you get written updates to read on your own time.
- A fixed daily overlap with your team
- Reviews and approvals inside that window
- Written updates for everything else
STAGE GATES
You Approve Each Stage Before the Next Starts
Each life-cycle stage ends with something you can review: a written brief, a clickable design, a working build. The next stage starts only after you approve it, so scope never drifts without anyone noticing.
- A deliverable at the end of every stage
- Your sign-off before the next one begins
- Changes recorded with their cost and timing impact
OWNERSHIP
Your Accounts, From the First Commit
Repositories, cloud accounts and domains are created in your company's name, not ours, before any code is written. If you ever change vendors, everything you need is already yours.
- Code in your repositories
- Cloud and domain accounts in your name
- Documentation that stays with the code

Custom Software Development in Atlanta — FAQs
Do you work with companies across metro Atlanta, including Alpharetta, Marietta and Sandy Springs?
Yes. We work with businesses throughout metro Atlanta, including Atlanta, Alpharetta, Marietta, Sandy Springs, Duluth and Peachtree Corners, and elsewhere in Georgia. All of our work is remote with a daily Eastern Time overlap, so your location doesn't change how the project runs.
Is bespoke software the same as custom software?
Yes. Bespoke software, tailored software and custom software all describe software built to one organization's requirements and owned by that organization, as opposed to off-the-shelf software sold to many customers. "Bespoke" is more common in British English, and "custom" is more common in the US.
Our SAP ECC maintenance ends in 2027. What happens to our custom code?
Each customization needs a decision: retire it, rebuild it inside the new ERP, or rebuild it as a separate application connected through APIs. SAP's mainstream maintenance for core Business Suite 7 applications runs until the end of 2027, with optional extended maintenance to the end of 2030. We build the applications that sit beside the ERP and work alongside your SAP partner.
What is engineer-to-order software, and does our manufacturing business need it?
Engineer-to-order software supports manufacturers that design part of each product after the order is placed. It typically handles quoting and configuration, a bill of materials for each order, and engineering change tracking. If your quotes depend on engineers working through spreadsheets and email, you likely need it. Standard manufacturing systems are built for repeat production instead.
What happens at each stage of the software development life cycle?
A project moves through discovery, design, build, testing, release and support. Discovery decides which problem to solve first. Design confirms the software fits how people work. Build delivers features in short cycles. Testing checks function, security and performance. Release puts it in front of real users, and support improves it based on how they use it.
Does Georgia's new privacy law apply to our business?
It may. Georgia's Consumer Privacy Protection Act was signed on May 11, 2026, with an effective date of July 1, 2026, and applies to businesses that handle personal data of a large number of Georgia consumers. It gives consumers rights to access, correct, delete and opt out. Your counsel should confirm the final thresholds and how they apply to you.
Can you build a learning management system for our organization?
Yes. We build learning management software for training teams, schools and associations, with course delivery, enrollment, progress tracking, certificates and reporting. We usually recommend an existing platform first. Custom LMS work makes sense when your training is tied to your own systems, such as HR records or certifications that determine who can do which job.
