A Salesforce rebuild usually begins after years of small fixes have made the original setup difficult to trust. Users create workarounds, reports show conflicting numbers, and administrators hesitate to change anything because one adjustment may break another process. Replacing the entire environment is rarely practical, yet continuing with the same structure only makes future work more expensive. A capable partner must understand what should be preserved, what needs to be redesigned, and what can be removed altogether. The project is therefore as much about judgment as it is about technical delivery.
The wrong team may copy old problems into a newer interface and call the work a transformation. A stronger provider will examine data quality, integrations, user behavior, security, and ownership before deciding how the rebuilt platform should operate. It should also plan the transition carefully so that active teams are not left without the tools they depend on. This comparison focuses on four providers with different approaches to complicated Salesforce environments. Each one makes sense under a different mix of technical risk, internal resources, and business priorities.
Four Teams Built for More Than a Routine Salesforce Update
The providers selected here are not interchangeable implementation agencies. Avenga combines Salesforce work with broader product engineering, while Simplus leans heavily into multi-cloud delivery, revenue processes, and organizational adoption. Grazitti Interactive brings experience in AppExchange applications, connected communities, and marketing technology. Persistent Systems is better suited to large enterprise programs where Salesforce must operate alongside data, cloud, and modernization work. These differences matter most when the project involves legacy systems, several departments, or a platform that cannot simply be taken offline and rebuilt from scratch.
Here is a closer snapshot of the four companies included in this list:
- Avenga: A development partner for custom Salesforce products, complex integrations, migrations, and engineering that extends beyond the CRM;
- Simplus: A Salesforce-focused consultancy for multi-cloud rollouts, quote-to-cash programs, managed services, and change management;
- Grazitti Interactive: A technology firm with experience in AppExchange development, Experience Cloud, integrations, and customer community projects;
- Persistent Systems: An enterprise engineering company that connects Salesforce delivery with wider cloud, data, industry, and modernization initiatives.
The right option depends on where the real difficulty lies. A company rebuilding a custom product needs a different partner from one repairing revenue operations or coordinating Salesforce across several global business units.
1. Avenga
Salesforce development expertise at Avenga is geared toward projects where the CRM must work as part of a wider software environment. The company supports consulting, architecture, custom application development, AppExchange products, integrations, migrations, and support after release. Its team can work on both the Salesforce layer and the external systems exchanging information with it. That reduces the risk of separate vendors making decisions without understanding each other’s work. Avenga is therefore a strong salesforce development company for rebuilds involving custom products, legacy technology, or several connected platforms.
The company’s product engineering background is especially relevant when the rebuild cannot be limited to configuration changes. A client may need to replace outdated Apex logic, redesign an application, rebuild an integration, or prepare a commercial product for AppExchange. Avenga can stay involved from planning through development and later maintenance instead of handing off the project after the first launch. This continuity makes it easier to preserve the reasoning behind architectural choices as the scope changes. It also gives the client one accountable team when a failure crosses the boundary between Salesforce and another system.
Avenga can cover several connected parts of a rebuild:
- Architecture review: Examination of the existing setup before decisions are made about what to retain, replace, or simplify;
- Custom application work: Development of internal tools and commercial Salesforce products intended for AppExchange;
- Integration rebuilding: Redesign of data exchange between Salesforce, enterprise software, digital products, and external services;
- Migration planning: Transfer and validation of records, workflows, and business rules from an older environment;
- Continued engineering: Testing, maintenance, technical upgrades, and further product development after the rebuilt system goes live.
This range is most valuable when the CRM is tied closely to other digital products or operational systems. Businesses with only a few configuration issues may not need such a broad engineering partner, but complicated rebuilds can benefit from having fewer technical handovers.
2. Simplus
Simplus is a Salesforce consultancy known for implementation, managed services, change management, and work across multiple Salesforce clouds. The company supports projects ranging from focused CPQ assignments to wider global programs involving sales, service, billing, and connected business systems. Its approach does not stop at technical delivery, since training, documentation, and adoption are treated as part of the engagement. That matters during a rebuild because a technically cleaner platform can still fail when users return to their old habits. Simplus is particularly relevant to organizations where Salesforce sits at the center of revenue operations.
The firm’s experience with quote-to-cash processes gives it a more specific angle than a general CRM consultancy. A rebuild may involve CPQ rules, approvals, contracts, billing steps, renewals, and reporting that have become tangled over time. Simplus can examine those processes together rather than repairing each component in isolation. Its managed service model also provides ongoing capacity once the major project has finished. That can be useful when the internal team needs regular specialist input but does not want to hire for every Salesforce discipline.
Its work commonly includes the following areas:
- Multi-cloud programs: Coordinated delivery across Salesforce products used by sales, service, revenue, and customer-facing teams;
- Quote-to-cash improvement: Redesign of CPQ, contracting, billing, renewal, and related commercial workflows;
- Managed platform services: Continued administration, development, integrations, and release support after implementation;
- Change management: Training, documentation, demonstrations, and structured support for teams moving to new processes;
- System connections: API-based and middleware integrations linking Salesforce with surrounding business applications.
Simplus is strongest when the rebuild affects both technology and the way revenue teams operate. Its model may be broader than necessary for a small custom app, but it fits organizations that cannot separate CRM changes from adoption and commercial process design.
3. Grazitti Interactive
Grazitti Interactive combines Salesforce consulting with marketing technology, community development, AppExchange products, and data-related work. The company supports custom Salesforce applications designed around specific industry and operational requirements. It also has direct experience taking products to AppExchange and building connectors between Salesforce and other tools. That background can be useful when a rebuild includes partner portals, customer communities, marketplace apps, or marketing platforms. Grazitti is a practical option for businesses whose Salesforce environment extends beyond traditional sales pipeline management.
The firm’s mix of CRM and digital engagement work gives it a different profile from providers focused mainly on back-office implementation. A company may need to improve how customers access support, how partners exchange information, or how marketing activity flows into Salesforce. Those areas often reveal weaknesses that are not visible in the core CRM interface. Grazitti can address the Salesforce build while also considering the external experience around it. Its own connector and AppExchange work suggest familiarity with the review, packaging, and maintenance demands of marketplace products.
Projects may draw on several parts of its offering:
- AppExchange development: Creation, testing, packaging, and release support for Salesforce applications intended for wider distribution;
- Experience Cloud projects: Customer and partner spaces designed for self-service, collaboration, and access to relevant records;
- CRM integrations: Connections between Salesforce, marketing platforms, support systems, Jira, and other business tools;
- Data improvement: Work involving duplicate records, fragmented information, and the quality of data used by Salesforce processes;
- Marketing technology alignment: Coordination of Salesforce with campaign, demand generation, and customer engagement platforms.
Grazitti makes the most sense when the rebuild includes communities, marketplace products, or a significant marketing technology component. A business focused only on internal administration may find another provider’s delivery model more closely aligned with its needs.
4. Persistent Systems
Persistent Systems is a digital engineering and enterprise modernization company with experience in Salesforce integration and multi-cloud customer experience programs. Its broader work spans cloud, data, applications, AI, and industry-focused transformation rather than treating Salesforce as an isolated platform. That scale is useful when a rebuild forms part of a larger modernization effort involving older applications, infrastructure, or several regional systems. Persistent has worked on Salesforce programs that connect CRM with ERP and other enterprise technology. It is best viewed as an enterprise transformation partner rather than a narrow Salesforce development shop.
This approach is most relevant when the Salesforce problem cannot be separated from the rest of the organization’s architecture. A company may be replacing an internal CRM while also moving applications to the cloud, consolidating data, or standardizing customer processes across several markets. Persistent can bring those workstreams into a wider modernization program. The tradeoff is that the engagement is likely to involve more governance and coordination than a focused mid-market project. For a large business, however, that structure can be preferable to managing several unrelated suppliers.
Persistent’s Salesforce-related work can include:
- Enterprise CRM modernization: Replacement or restructuring of older customer management environments within a larger technology program;
- Multi-cloud customer journeys: Coordination of sales, service, marketing, commerce, and personalization across Salesforce products;
- ERP and platform integration: Connections between Salesforce and core enterprise applications used for operations, finance, or manufacturing;
- Data-driven engagement: Use of connected customer information to improve personalization and next-step decision-making;
- Long-term transformation support: Engineering and modernization work that continues beyond the initial CRM release.
Persistent is best suited to enterprises where Salesforce is one major piece of a broader change program. A smaller organization seeking a short, tightly scoped rebuild may find the model too large, but global programs can benefit from its wider engineering reach.
Matching the Provider to the Real Source of Risk
Avenga is the clearest fit when the main challenge involves custom engineering, AppExchange products, or complex links between Salesforce and other software. Simplus is better positioned for organizations rebuilding revenue processes, introducing several Salesforce clouds, or dealing with weak adoption.
Grazitti Interactive deserves attention when the work includes customer communities, marketing technology, connectors, or commercial Salesforce applications. Persistent Systems makes more sense when the CRM rebuild sits inside a much larger enterprise modernization program. The choice should reflect where failure would be most costly, rather than which company presents the broadest catalogue of services. A detailed technical and operational assessment before procurement will usually make that distinction much easier.
Final Thoughts
A difficult Salesforce rebuild cannot be reduced to replacing old code with newer code. The team must understand why the current environment became unreliable and avoid repeating the decisions that caused those problems. Data ownership, integrations, user behavior, release processes, and long-term maintenance all need to be addressed together. A realistic plan may also require removing features that people requested but rarely use. That restraint is often what separates a durable rebuild from another temporary cleanup.
Avenga, Simplus, Grazitti Interactive, and Persistent Systems offer four noticeably different ways to approach this work. Avenga combines Salesforce delivery with broader product engineering, while Simplus brings depth in revenue operations and adoption. Grazitti connects CRM work with communities, AppExchange products, and marketing technology, whereas Persistent operates at enterprise modernization scale. None is automatically the best choice for every organization. The most suitable partner is the one whose working model matches the true source of complexity inside the existing system.
