ERP Implementation and Consulting

PS3G provides ERP implementation and consulting for organizations of every size: selecting the right system, configuring and extending it, migrating your data, integrating it with the web, mobile and data platforms around it, and supporting it after go-live. Whether you are a founder outgrowing accounting software and spreadsheets, an operations lead replacing a system the vendor stopped supporting, or an IT director rolling a group standard out to a new division, the risks are the same and so is the method. We are Dynamics 365 and SAP specialists with the software engineering depth to build what the ERP does not do out of the box.

ERP without the horror stories

ERP projects fail in familiar ways: the old process is copied into the new system, the data arrives dirty, nobody on the business side owns the decisions, testing is cut to hit a date, and training is a one-day event. None of those failures is caused by the software. They are caused by how the project is run, which means they are avoidable.

Our ERP consulting starts with your processes and your data, not with a license quote. We help you pick a system that fits the size you are now and the size you plan to be, we keep customization to what the business case justifies, and we rehearse the cutover before it happens.

A small company usually gets Dynamics 365 Business Central with limited extensions, a clean migration of open balances and master data, and a short training plan. A mid-sized company gets a phased rollout across entities or sites with integrations to its CRM, web store and warehouse. A division inside a larger group gets a template rollout under corporate standards and change control. The engineering is the same; the engagement is scoped differently.

What we do

• Selection. Requirements by process, a shortlist, scripted demos with your own scenarios, reference checks, and a written recommendation with total cost of ownership over several years.
• Implementation. Fit-gap analysis, configuration, process design, security roles, workflow and approvals, reporting, and a phased or single-cutover plan with go and no-go criteria.
• Customization and extensions. AL extensions for Business Central, X++ for Dynamics 365 Finance and Supply Chain, ABAP and SAP BTP for S/4HANA, and Power Platform apps and automations around any of them, built by our .NET development team when the requirement is a custom application rather than an extension.
• ERP integration. Connecting the ERP to CRM, e-commerce, warehouse, payroll, banking, EDI partners and your data platform, with monitoring and error handling.
• Data migration. Scoping which history to bring, cleansing and mapping master data, repeated mock loads, and reconciliation of balances, open items and inventory before cutover.
• Training and change. Role-based training, super users in each department, and documentation your team keeps after we leave.
• Support. Hypercare after go-live, then managed support under defined SLAs, including updates, new extensions and reporting changes.

Our deepest expertise is in Microsoft ERP, which sits naturally alongside our Microsoft technology services (Azure, .NET, SQL Server, Power Platform, Microsoft 365). We recommend a platform only after looking at your processes, your other systems and your team.

Integration with web, mobile and data platforms

An ERP earns its keep when it stops being an island. We connect it to the systems around it with native connectors where they exist, APIs and middleware (Azure Logic Apps, Power Automate, SAP Integration Suite) where they do not, and event-based patterns where volume or timing requires it.

• Web and e-commerce: customer portals, order entry and web stores that read prices, stock and order status from the ERP and write orders back, built by our API development and integration team.
• Mobile: field service, warehouse scanning and approvals apps that work offline and sync to the ERP.
• Data and reporting: ERP data landed in a warehouse or Microsoft Fabric and modeled for Power BI, so reporting does not run on the transaction database; see our data analytics and BI services.
• Automation: invoice capture, bank reconciliation, order entry from emailed documents and other repetitive tasks handled by RPA and AI workflows on our AI and RPA page, so the ERP is fed without re-keying.

Our phased ERP implementation approach

1. Assess. Process walkthroughs with the people who do the work, a data health check, and an integration inventory. Output: a written scope, risks and a phased plan.
2. Design. Fit-gap by process, configure-versus-customize decisions, security roles, reporting requirements and the data migration plan.
3. Build. Configuration, extensions, integrations and reports, with a first mock data load early enough to find the surprises.
4. Test. Unit, integration and user acceptance testing against your scenarios, a performance check, and a full cutover rehearsal, run with our testing center of excellence.
5. Train and cut over. Role-based training, a transaction freeze, the final load, reconciliation, and a go or no-go decision on agreed criteria.
6. Hypercare and support. Daily check-ins for the first close, then managed support and a backlog for the next phase.

Ask for a fixed-scope proposal for an assessment or a full implementation.

Engagement models

• Fixed-scope project: an assessment, a selection, or a complete implementation of a defined scope at a written price.
• Dedicated team or staff augmentation: functional consultants and developers working inside your project team on a monthly basis.
• Managed services: post-go-live support, updates, extensions and reporting changes under defined SLAs.
• Advisory: selection, project rescue, independent review of a partner’s proposal, fractional CIO for the program.

How we start: a first conversation, a short assessment, and a written proposal.

Why PS3G

• Over a decade of software and systems work, with a US headquarters in Wilmington, Delaware and a delivery center in India for extended coverage during cutovers and month-end.
• We build and run our own products, including our HIPAA-compliant EHR and telehealth platform, DocVilla, so we know what it means to operate a system other businesses depend on daily.

Frequently asked questions

How long does an ERP implementation take?

It depends on scope: the number of entities and sites, how many processes are in scope, how much customization and integration you need, and how clean your data is. A single-entity Business Central rollout with few extensions is a matter of months; a multi-entity Dynamics 365 Finance or S/4HANA program runs in phases over a longer period. The proposal states the timeline for your scope in writing.

Which is right for us, Business Central or Dynamics 365 Finance and Supply Chain?

Business Central fits most small and mid-sized companies that need finance, inventory, purchasing, sales and light manufacturing in one system with limited complexity. Dynamics 365 Finance and Supply Chain Management fits larger organizations with multi-country operations, advanced manufacturing or warehousing, and the need for deeper configuration. We recommend one after a process walkthrough.

Is PS3G a Microsoft partner or an SAP partner?

We describe ourselves as Dynamics 365 and SAP specialists rather than by partner program status, and we are vendor-neutral in selection. What we bring is implementation experience plus the software engineering, integration and data teams to build what sits around the ERP. Ask us about licensing and partner arrangements for your specific platform on the first call.

Should we migrate all of our historical data?

Usually not. Most organizations migrate master data, open items (open invoices, purchase orders, inventory balances) and opening balances, and keep historical transactions in a reporting database or the old system in read-only mode. Full history migration costs more, slows the project and brings old errors with it. We decide per data category with your finance team.

What is cloud ERP software and should we choose it over on-premises?

Cloud-based ERP is hosted and updated by the vendor and accessed through a browser, with subscription licensing. Dynamics 365 and SAP S/4HANA Cloud are the main examples. For most organizations it removes server, backup and upgrade work and is the default choice today; on-premises or private cloud still makes sense for specific regulatory, connectivity or customization reasons.

Can you rescue an ERP project that has stalled?

Yes. A project rescue starts with an independent review of scope, data, integrations, testing and ownership, followed by a reset plan with clear go-live criteria. Often the system is fine and the project needs decisions, data cleansing and a rehearsal plan. We work alongside your existing partner when that is the best path, or take over delivery when it is not.
