B2B Software Consulting in Atlanta
Atlanta is card-processing country: Global Payments is headquartered here and moves volume across more than 175 countries, and NCR Voyix runs its global headquarters in the city. PCI DSS scope, not a state statute, decides your architecture. ERPStack is remote-first and builds order-to-cash ERP systems that keep the card number out of PostgreSQL entirely.
Quick Answer
In short: Atlanta is card-processing country. ERPStack builds Atlanta ERP to PCI DSS v4.0.1, including the 51 future-dated requirements live since 31 March 2025, using P2PE and tokenisation to cut audit scope, ISO 20022 messages on Fedwire, and Nacha Same Day ACH limits, in the AWS us-east-1-atl-2a Local Zone.

Security & Compliance Architecture
Atlanta’s binding rule is contractual, not legislative: PCI DSS reaches you through your acquirer and is validated by a QSA. The PCI Security Standards Council retired v3.2.1 on 31 March 2024, published v4.0.1 as a limited revision in June 2024, and switched on 51 of the 64 new requirements on 31 March 2025. Each one below lands somewhere in the schema or the pipeline.
Scope is the whole compliance budget
Every Atlanta assessment is priced by what is in the cardholder data environment. P2PE capture, tokenisation and network segmentation described in Terraform shrink that boundary, so the ERP, the CRM and the analytics warehouse sit outside it. ERPStack designs the boundary first and treats PCI DSS v4.0.1 as an input to the data model.The 51 future-dated requirements are live
Since 31 March 2025 an Atlanta merchant is assessed on payment-page script integrity, documented targeted risk analyses, and far broader logging. In engineering terms that is a content security policy with a nonce on every Next.js route, an inventory of third-party scripts, and log retention that survives a PCI DSS v4.0.1 Report on Compliance review.A QSA asks for evidence your CI already emits
Segmentation diagrams, change management, vulnerability findings and access reviews all exist in the repository before anyone requests them. ERPStack publishes GitHub Actions runs, Semgrep SAST and OWASP ZAP output, Playwright results and the RBAC model as artefacts, so an Atlanta assessment reads CI history instead of interviewing engineers.Disputes need an immutable audit trail
A chargeback is decided on evidence assembled months later, so an Atlanta ERP cannot let a representment overwrite the original capture. ERPStack keeps dispute state as an append-only journal in PostgreSQL with row-level security (RLS) per merchant, and stores compelling evidence in object storage under a retention lock rather than in a shared drive.What ERPStack is not in Atlanta
ERPStack is not a validated PCI DSS service provider and holds no SOC 2 or ISO 27001 attestation of its own — we say so before an Atlanta procurement asks. What we deliver is a system engineered to pass assessment: minimal scope, tokenised storage, RBAC and an immutable audit trail implemented directly in the PostgreSQL schema.
Engineering Blueprint
Software built in Atlanta usually touches a card transaction: Global Payments is headquartered here across more than 175 countries, NCR Voyix runs its global headquarters in the city, and 29 Fortune 500 and Fortune 1000 companies sit in the metro. So the first architectural decision in an Atlanta ERP is not a framework — it is keeping the primary account number out of PostgreSQL.
Atlanta has a real AWS Local Zone
Most city pages invent a region. Atlanta does not need one: AWS runs us-east-1-atl-2a, zone ID use1-atl2-az1, plus us-east-1-atl-1a on request, both parented to us-east-1. ERPStack puts the latency-sensitive tier — Next.js rendering, Redis, the authorisation API — in the Atlanta Local Zone and keeps the PostgreSQL system of record in us-east-1, with Terraform describing which subnet each workload may occupy.
Tokens in the ledger, PAN nowhere
Scope is the entire PCI DSS budget. When capture happens in a P2PE-validated device or the processor’s hosted fields, an Atlanta order-to-cash ledger stores a token, the last four digits and a network reference — not cardholder data. ERPStack enforces that with Zod at the API boundary and Drizzle ORM column types, so a PAN cannot be persisted even by accident.
// Zod + Drizzle ORM — Atlanta payment record, PCI DSS scope-out
export const payment = pgTable('payment', {
id: uuid('id').primaryKey().defaultRandom(),
processorToken: varchar('processor_token', { length: 64 }).notNull(),
last4: char('last4', { length: 4 }).notNull(),
networkRef: varchar('network_ref', { length: 32 }),
});
export const inbound = z.object({
processorToken: z.string().min(16),
pan: z.never(), // reject PAN at the REST boundary — never in PostgreSQL
});Settlement is a reconciliation loop, not a table
Authorisation, capture, settlement, interchange and chargeback arrive days apart and out of order, so an Atlanta payments ERP needs idempotency in API design and an event-driven architecture rather than nightly batch. ERPStack models each stage as an append-only event in PostgreSQL, replays them into balances, and reconciles the processor file against the ledger with a saga pattern that compensates instead of deleting.
Rails change — so make limits data
The Fedwire Funds Service has migrated to ISO 20022, and the Nacha Same Day ACH per-entry limit rises from $1 million to $10 million on 17 September 2027. An Atlanta ERP that hard-codes 1000000 as a constant will reject good payments that morning. ERPStack keeps rail limits and message versions as effective-dated rows in PostgreSQL, with Vitest cases pinned to the date.

Frequently Asked Questions
Of the 64 new requirements introduced in PCI DSS v4.0, 51 were future-dated and became effective on 31 March 2025, per the PCI Security Standards Council. Version 4.0.1 arrived in June 2024 as a limited revision, after v3.2.1 retired on 31 March 2024. For an Atlanta merchant that means script integrity, targeted risk analyses and expanded logging are now assessed, not aspirational.
SAP S/4HANA is the right call when Atlanta finance leadership needs statutory consolidation across many entities and can live inside the vendor's data model. Choose custom ERP development when the differentiator is the money movement itself — interchange decomposition, settlement matching, chargeback state machines. ERPStack builds the second in TypeScript and PostgreSQL, and concedes the first honestly.
Often yes. Odoo covers inventory, purchasing and invoicing for an Atlanta 3PL at that size for a fraction of a custom build. It stops being enough when your customers dictate EDI transaction sets, appointment scheduling at the dock and per-client billing rules that Odoo Enterprise can only express as scripts. ERPStack will tell you which side of that line you are on.
No. ERPStack is remote-first: no Atlanta office, no local staff. What matters is deploying into us-east-1-atl-2a, the Atlanta Local Zone AWS actually operates, and knowing that your acquirer and QSA — not Georgia's legislature — set the controls your ERP has to satisfy. We work in your review cadence and your ticketing.
By removing the primary account number from systems you own. If the card is captured by a P2PE-validated device or the processor's hosted fields, your PostgreSQL tables hold a token, the last four digits and a network reference — none of which is cardholder data. The Atlanta ERP then falls out of scope for most of PCI DSS v4.0.1, and the assessment shrinks to the boundary.
Anything that parsed fixed-width remittance text. Fedwire Funds Service formats now align with the ISO 20022 messages other high-value systems use, which means structured party data and richer remittance. ERPStack stores the message as versioned data in PostgreSQL, maps fields with Zod schemas per version, and keeps the raw payload so an Atlanta reconciliation can be replayed.
The per-entry limit rises from $1 million to $10 million effective 17 September 2027 under the Nacha Operating Rules. Any Atlanta ERP that hard-codes $1,000,000 as a validation constant will reject legitimate payments that day. ERPStack keeps network limits as effective-dated configuration rows, covered by Vitest cases pinned to the change date.
Scope diagrams first, then proof the controls run. A Qualified Security Assessor validating PCI DSS wants segmentation evidence, change management from GitHub Actions, vulnerability output from Semgrep SAST and OWASP ZAP, access reviews from the RBAC model, and log retention. ERPStack emits those as CI artefacts from the Atlanta project repository rather than assembling them at assessment time.
No. ERPStack is a remote-first engineering firm, not a validated PCI DSS service provider, and does not appear on any acquirer's service provider list. We design so that your Atlanta cardholder data environment stays small: tokenised storage, segmented networks in Terraform, an immutable audit trail, and RBAC that a QSA can test directly against the PostgreSQL schema.
